Category:Taxa by author diffusion

Are Category:Animal taxa by author (2,036) & Category:Botanical taxa by author (1,065) intended to be mutually exclusive from Category:Taxa by American author (533), etc.?

If so, it's unclear which is the preferred destination. Should an American animal taxa author go into Animal taxa by author or Taxa by American author?

If not, Animal & Botanical will need further diffusion into their own nationality layers, which seems overly redundant, complicated, and bloaty.

Both Category:Animal taxa by author (2,036) & Category:Botanical taxa by author (1,065) were created by now-blocked, problem-producing editors in taxonomy-space, so my guess is that they should be deleted in favor of the national categories. Also, I think that having nationality above group makes more sense than having multiple national layers below Animal/Botanical/etc., since nationality-above-group will naturally result in fewer overall categories. There's only 1 nationality category that might need diffusion in the foreseeable future, Category:Taxa by American author (533), which can be done by simply diffusing into whatever the most popular taxa group is for American authors (Animal, Botanical, etc.).

I am very not equipped to comment on taxonomy generally BUT I think it's weird to have plants vs animals bc we also need to then consider fungi and kelp and slime molds (whatever they even are) and the whole catalogue of cooties (viruses, bacteria, and all their little friends). So. My thought is just...taxa. Full stop. Don't subdivide by types of taxa. If you want to subdivide the NAMERs of the taxa by century or nationality or what have you, sure, whatever. Good luck and bye! :D jengod (talk) 20:49, 29 August 2024 (UTC)

I agree that Animal vs Botanical should be deleted. Some of these namers addressed both plants and animals (and I am sure fungi too) so that split doesn't make sense. I am not convinced we need a nationality split either but that one is at least sensible. Rlendog (talk)

Absolutely - what happens if someone dares to identify both flora and fauna? --Prosperosity (talk) 21:01, 29 August 2024 (UTC)

A possible interpretation here is that the animal/botanical split refers not to the Kingdoms, but to the nomenclatural codes (in which case "fungi and kelp and slime molds" come under botanical). But there are also the bacterial and virological codes, and PhyloCode. (One might argue that PhyloCode isn't used widely enough for Category:PhyloCode taxa by author to be useful.) Lavateraguy (talk) 11:20, 1 September 2024 (UTC)

I'm not fully sold on the need for someone to look up taxa based on the citizenship of the author, but that's pretty standard for Wiki categories so it makes sense. --Prosperosity (talk) 21:01, 29 August 2024 (UTC)

I wasn't aware of the nationality categories before, and I don't think they've been previously discussed anywhere. Category:Taxa named by Carl Linnaeus is in both the the animal category and the botanical category, and I'm sure there are other taxonomists in both categories. The botanical category does specify that it covers "plant and cryptogam taxa (lower plants, fungi, lichens, algae)". I think the animal and botanical categories aren't particularly useful and could be eliminated. I don't think we really need to diffuse Category:Taxa by author at all, and the nationality categories could be eliminated as well. Plantdrew (talk) 21:19, 29 August 2024 (UTC)

Someone being in both Animal & Botanical is ok. I just don't see the point of having (Animal|Botanical) and (nationality) at the same level...unless...(Animal|Botanical) is declared non-diffusing. I'd be ok with that.

There are ~5600 unique "Taxa named by <author>" categories, and always growing, which I think is worthy of diffusion.   ~ Tom.Reding (talk ⋅dgaf)  22:15, 29 August 2024 (UTC)

My intent of beefing up the taxa by nationality was to get those categories out of the FOOian people by nationality categories that they were showing up in. I personally don't find the animal vs botantical distinction to be very helpful, but I assumed that other people who know more about tax do. Mason (talk) 23:16, 29 August 2024 (UTC)

Interesting discussion, thanks for the ping! Not very experienced with categories so hopefully I'm understanding everything correctly. I think the animal/botanical(/additional categories for other eukaryotes, prokaryotes, and virus taxa?) distinction can be valuable, but agree that it definitely should not be mutually exclusive with nationality categories. Ethmostigmus 🌿 (talk | contribs) 06:58, 30 August 2024 (UTC)

Get rid of the nationality part. it's irrelevant. Two prolific authors I can think of, George Albert Boulenger and Albert Günther, were dual nationals, and there will be many more. I also don't think we need anything more than "Taxa named by", so agree with removing the references to animals and plants. Quetzal1964 (talk) 07:19, 30 August 2024 (UTC)

Someone being in 2+ nationality cats is ok. Someone being in both Animal & Botanical is ok. Someone being in any of (American|Australian|...) AND any of (Animal|Botanical|...) is the main question here, and which of these 2 sets, if any, should exist.   ~ Tom.Reding (talk ⋅dgaf)  09:33, 30 August 2024 (UTC)

• When I first proposed these taxa by author categories back in the day, there were no suggestions to specify further than just author. So I wonder if nationality and field are even needed. FunkMonk (talk) 07:31, 30 August 2024 (UTC)

I do not see Animal & Botanical as being mutually exclusive with each other or with the nationality cats. Only having nationality category makes categories difficult to find, especially when one does not know the full name and identity of an author, or when there are spelling variations. Therefore I object to only having nationality-based categories, but I am OK with these otherwise. I see a need for diffusion but the Animal/Botanical split is quite sufficient. To me a bigger problem is propagation of categories with one or few articles, without much prospect of them becoming more populated. When does an author deserve a category? There is no good answer, and this was the reason I was initially quite sceptic to the "Taxa by author" system. Now I kind of like it because it highlights the people behind taxonomy, but the notability issue remains unresolved. Cheers, Micromesistius (talk) 11:55, 31 August 2024 (UTC)

I personally vote to get rid of the field categories. The animal/botanical split is archaic, unrealistic, and completely subjective, so it should not be considered. I have no issue with the nationality categories as it could be an interesting source of demographical data, but I also have no issue with removing them if that is the consensus (also, people can have more than one nationality, and some believe to be better represented by their ethnicity than by their national status). — Snoteleks (talk) 15:28, 31 August 2024 (UTC)

When you say get rid of the field categories, do you mean to do away with taxonomic categorisation for authors entirely, or replacing the animal/botanical author categories with something more comprehensive? I wouldn't consider the animal ("zoological" would be a better term IMO)/botanical split subjective - I interpreted it as referring to to taxa covered by the ICZN vs the ICNafp, and I think distinguishing between authors publishing on animals and authors publishing on plants/fungi/algae can be useful. These two categories obviously fail to address all the organisms outside of those groups, but I would prefer to see more comprehensive categorisation than do away with taxonomic distinctions entirely. Interested to get your thoughts on this given that I know your interests lie with organisms that fall outside of the existing categories. Ethmostigmus 🌿 (talk | contribs) 04:45, 1 September 2024 (UTC)

The ICZN and ICNafp overlap in many protozoan groups, that's my primary concern. Authors that study protists such as Labyrinthulomycetes, Bicosoecida, Euglenida, Katablepharida and Myzozoa could belong to either of those categories, as there is no consensus (and no desire for consensus) on which nomenclatural code has domain over them. In all of those, both zoological and botanical suffixes of taxon ranks have to be used because the codes refuse to collaborate with each other. Ideally we would be able to firmly separate one from the other, but the reality is that it's subjective in the sense that it depends entirely on the author's preference for these ambiregnal groups.

However, even assuming that we collectively decide to maintain these categories, we could not even firmly separate them ourselves in Wikipedia to avoid any overlap. There are groups which, by consensus, have botanical suffixes in some taxon ranks, but zoological suffixes in others. Perhaps it would be better to have "animal", "plant", "fungal", "protist" and "prokaryotic" categories instead. — Snoteleks (talk) 12:19, 1 September 2024 (UTC)

My two cents, as an ICZN Commissioner, is that the plant/animal categorization is definitely artificial, and definitely has a fair-sized "fuzzy area", which argue against the maintenance of those sub-categorizations. I have an even stronger objection to categorization according to nationality of authors, because "nationality" is even MORE artificial, and can also be pretty darn fuzzy; not just authors with multiple citizenships, but authors whose countries have changed (e.g., how does one categorize an author from the former Soviet Union, or pre-Soviet Russia?), or authors born in one country, but who lived and worked elsewhere without citizenship there? If I want to know where an author was born, or their citizenships, I can look up their linked biography. If they are not notable enough to have a linked biography, then I wouldn't care where they were from. Categorizing taxa by their author's name, by their year of description, and by their biogeographic region or continent are all fine, but I have trouble with sub-categories within these (including subdividing biogeographic regions or continents into countries, which are, as noted, artificial boundaries and subject to change). Dyanega (talk) 15:49, 3 September 2024 (UTC)

My thoughts exactly. — Snoteleks (talk) 12:46, 4 September 2024 (UTC)

So it looks like there's consensus to get rid of the nationality layer, as no one finds it useful. @Smasongarrison: is that ok with you?   ~ Tom.Reding (talk ⋅dgaf)  18:24, 9 November 2024 (UTC)

As I said before my problem is that these categories keep showing up in FOOian people by nationality categories, where they're really don't belong. So they might not be directly useful for Taxony, but they're really useful for keeping them isolated from the rest of the people categories. I'd be fine with an alternative categorization that solved this problem or a policy that these categories don't belong in the rest of the tree. But, they serve a basic use of diffusion. ^SMason_Garrison 18:37, 9 November 2024 (UTC)

What's an example of one of the FOOian categories that these keep populating? I'm ok with the taxa by nationality cats if they're part of a larger structure.   ~ Tom.Reding (talk ⋅dgaf)  20:59, 9 November 2024 (UTC)

Here's the example I tidied up today. Category:Taxa named by Carl Borivoj Presl was in Czech botanists, before I cleaned these kinds of categories. They were often placed in all the same categories as the person who named the taxa, such as FOOth-century botanists, FOOth-century Czech scientists etc. It's just really annoying because the contents of the taxa category never apply to these kinds of pages. ^SMason_Garrison 22:13, 9 November 2024 (UTC)

Is the problem that Carl Borivoj Presl is placed in category Category:Taxa named by Carl Borivoj Presl, when of course he isn't a taxon named by himself? The other categories in Category:Taxa by Czech author don't include the author (at least the few I checked).  —  Jts1882 | talk  07:54, 10 November 2024 (UTC)

Partially, but at the heart of it the entire category often gets treated like Carl Borivoj Presl, almost like it's an incorrectly named eponymous category. ^SMason_Garrison 12:20, 10 November 2024 (UTC)

Arachnids by year of formal description

Kodiak Blackjack is creating an Arachnids by year of formal description category tree.

Given the 2018 RfC on limiting the number of branches & layers of the described-in tree, and that several arachnid-related cats were previously CfD'd (ticks & mites), and that I couldn't find any consensus to create an arachnid tree, do we want to crproposed cat deletion: eate an arachnid tree?   ~ Tom.Reding (talk ⋅dgaf)  11:02, 2 October 2024 (UTC)

Slightly off-topic: shouldn't those 1757 dates be 1758?

The zoological code (4th ed) says:

3.1. Works and names published in 1758. Two works are deemed to have been published on 1 January 1758:

- Linnaeus's Systema Naturae, 10th Edition;

- Clerck's Aranei Svecici.

(There's a 1757 beetle too...)
Kweetal nl (talk) 11:26, 2 October 2024 (UTC)

You're correct; there are no available names in zoology that were, formally, published before 1 January 1758. Regardless of the actual date of Clerck's work, it's considered to be dated 1758. If you want to be super-pedantic about it, the citation would appear "Clerck, 1758 ("1757")", following Rec. 22A of the ICZN. As for proliferation of categories, if these changes are being made without consultation or consensus, then there is a significant chance that some of the new categories are going to be extremely underpopulated. If there's only one species in, say, "Echinoderms described in 1795" then that may be oversplitting. Metrics on category constituencies might be persuasive one way or the other. Dyanega (talk) 14:47, 2 October 2024 (UTC)

Have read through the RfC. Was unaware of it before (I did get a couple of notices that some of the categories I was recreating were previously deleted, but the reason given was WP:C1).

My thoughts on creating the arachnid tree: when looking through the categories previously, I saw that a lot of arachnids (mites, scorpions, and ticks especially) would be lumped into "Animals described in XXXX," while spiders got their own category. Which is probably justifiable given the amount of spider species, but having a category tree that encompassed all arachnids at the class level seemed to make more sense than skipping straight to orders.

Re: 1757/58, if we want to put all the 1757-dated species into 1758, I don't have any objections to that. With regards to the beetle, it appears to have been synonymized with Dorcadion crux (Billberg, 1817) judging by the article's reference, so that just limits it to those in Systema Naturae and those in Aranei Svecici. I feel like there should be some categorical distinction between those, but I don't know how we would or if we even should go about that.

Re: categories being underpopulated, this is inevitably going to be true for some years and some taxa. It is also a problem that will eventually solve itself as new articles are created and added to their respective year of description categories. I think that the benefits of having a framework in place for future articles (or poorly-categorized articles) outweigh the downsides of having some be underpopulated... to an extent. If categories at the class level are underpopulated, it doesn't make sense to split it further until there's an actual need for diffusion.

So I'm in favor of an arachnid tree (obviously), neutral on having a spider tree, opposed to anything further (ticks, mites, etc.) for the time being.

@Tom.Reding @Kweetal nl @Dyanega Apologies for the pings, everyone. It's been a little more than a week since the last reply, so I'd just like to keep the ball rolling towards some sort of consensus. Any thoughts on the above (and echinoderms/etc.)?

— Kodiak Blackjack (talk) • (contribs) 18:12, 12 October 2024 (UTC)

The default position should be to stop creating new categories, as described in the RfC that you've read.   ~ Tom.Reding (talk ⋅dgaf)  19:20, 12 October 2024 (UTC)

Myself, I'm a little more ambivalent, and mostly concerned with the overall hierarchy of categories. For example, I agree with Kodiak that if the only echinoderm category is starfish, that this is bad. I would favor replacing the starfish category with a broader echinoderm category; this wouldn't increase the overall number of categories - it's a net zero - but it'd establish a more useful and logical piece within the hierarchy, and get more taxon articles into a more useful categorization. It's a balancing act, and I would think that so long as the end result is not a much greater total number of categories, that re-organization like this is desirable. Dyanega (talk) 16:05, 14 October 2024 (UTC)

(Previously uninvolved editor) I have to say I am with Kodiak and Dyanega here. Given we are talking about categorisation by year of description and therefore information aimed specifically at people interested in taxonomy, the current system which recognises a taxonomically-arbitrary set of groups (spiders but not other arachnids, starfish but not other echinoderms, etc.) seems bizarre. We should give some weight to the six-year-old RfC quoted above, but only about a dozen people commented. I think there should still be room to propose logical improvements to the system. YFB ¿ 17:35, 14 October 2024 (UTC)

Category creation is fine as long as there's vocal consensus (i.e. not WP:SILENT) prior to creation.   ~ Tom.Reding (talk ⋅dgaf)  18:06, 9 November 2024 (UTC)

Echinoderms by year of formal description

Same question for Category:Echinoderms by year of formal description.   ~ Tom.Reding (talk ⋅dgaf)  11:26, 2 October 2024 (UTC)

Same reason for the arachnid tree. We had a few categories for starfish described in <x year>, made more sense to have categories encompassing all echinoderms instead of stranding cukes, crinoids, urchins, etc. in the animals tree.

I would be in favor of deleting the starfish categories for the time being, though - I don't think there's enough volume to justify it at this point.

— Kodiak Blackjack (talk) • (contribs) 12:34, 3 October 2024 (UTC)

Etc. by year of formal description

See Category:Described in year with manual category (23) for more (includes some valid cats, like spiders).   ~ Tom.Reding (talk ⋅dgaf)  14:11, 2 October 2024 (UTC)

There, I just screwed the pooch and manually added categories which I wasn't aware were automatically added by the Category described in year template. Mea culpa. Will clean up the mess there later today.

— Kodiak Blackjack (talk) • (contribs) 12:39, 3 October 2024 (UTC)

Update: Have fixed all the echinoderm, spider, starfish, and arachnid categories in the maintenance category you mentioned, as well as sponges described in 1814. I didn't have a hand in creating all of the spider or starfish categories, but I fixed their manual category errors while I was going down the list for convenience's sake. Everything left, I had no involvement with.

The bee, bug, cockroach, damselfly, fly, grasshopper, sawfly, and wasp categories seem excessive - again, don't think there's enough volume at the moment to justify diffusing insects beyond the already-existing category trees for beetles, butterflies, and moths.

New citation template: Cite NatureServe

A long overdue template for citing NatureServe Explorer has been created. Template:Cite NatureServe. – Elizabeth (Eewilson) (tag or ping me) (talk) 23:49, 8 November 2024 (UTC)

Is it too much original research when the etymology of a taxon is completely obvious but unstated?

Within the king crabs, there is a subfamily Hapalogastrinae and a genus Hapalogaster. Their etymology in their original 1850 descriptions are unstated, but these are extremely clearly derived from the two Ancient Greek words ἁπαλός (hapalós) and γαστήρ (gastḗr) (together meaning "soft-bellied"). This is especially evident because the main defining aspect separating them from the rest of the lithodids is that the abdomen folded against their cephalothorax (basically functioning as their belly) is not calcified and therefore soft. Do Wikipedians generally consider this to be original research, or would this be something more along the lines of WP:TRANSCRIPTION? TheTechnician27 (Talk page) 01:16, 12 November 2024 (UTC)

In my interpretation on this, if you were directly asked Is this THE ACTUAL etymology that the describing author intended? we have to say no, as they never stated it. We have to word any etymology section as neutral and with backing sources, thus if we say the etymology is ἁπαλός (hapalós) and γαστήρ (gastḗr) (together meaning "soft-bellied")" we need to avoid any implication that it was the original authors indent. This is what happens when verifiability runs into older names combined with a crufty need for providing a name translation for all names.

Also as a personal note I truly detest the "(together meaning xxxx") structure used by kids books, rarely do you ever see any describing author use that formatting, and its not actually what its means, its what a very poor English spit-take of the name would be. I only ever discuss the root words/names and what they as single words translate to. We never go around talking about the new three-horned face fossils that were found or the disjunct distribution of "rounded Ypresian ant", "Bartletts Ypresian ant" with "eastern Ypresian ant". We shouldn't continue to normalize a low quality source practice.--Kevmin § 01:39, 12 November 2024 (UTC)

Interesting question! Unless a source discusses the etymology, yes, I would consider it original research and not transcription. I often come across secondary sources that posit theories on the etymology of a name when the original description fails to provide any, and adding this to an article is fully acceptable, but in my opinion etymology information in articles must reference a source that discusses the taxon in question. Ethmostigmus 🌿 (talk | contribs) 01:51, 12 November 2024 (UTC)

It is best practice to only record an etymology if one is clearly stated by a reliable source, and we should beware of creating a folk etymology for a scientific name. That said, I think it can be permissible if the etymology is clearly implied in context; 19th-century authors could generally assume their readership knew Greek and Latin, so they'd say things like "owing to its long tail, I propose to name this species Examplesaurus longicaudus" and leave the actual translation as an exercise for the reader. Does the original description of Hapalogaster clearly imply that it is named for having a soft belly? Ornithopsis (talk) 03:34, 12 November 2024 (UTC)

@Ornithopsis: Unfortunately no, but your example makes a lot of sense. The original description of Hapalogastrinae (subtribe Hapalogastrica -> family Hapalogastridae -> subfamily Hapalogastrinae) exclusively talks about its abdomen, but it unfortunately doesn't directly imply an etymology. JF Brandt, 174 years later, some amateur naturalist is very disappointed in you. TheTechnician27 (Talk page) 01:40, 13 November 2024 (UTC)

You shouldn't be stating the etymology as fact, but in my opinion it's fine to state the meanings of those words as "related facts" and let the reader draw conclusions if they want to. For example:

Myzobdella is a genus of leech. [...] In Greek, μυζω means "I suck" and βδελλα, leech.

But others might complain.

Also, I hate it when taxon authors don't provide etymology, especially, when the etymology is weird or obscure. On the other hand, I also don't like it when they call the species viridis or gigantea or something and just call it day.Cremastra ‹ u — c › 01:33, 28 November 2024 (UTC)

And sometimes a source will speculate for us.[1] Donald Albury 16:57, 28 November 2024 (UTC)

I think the point that Ornithopsis makes is very sound: in the past, etymologies weren't provided when the meaning would have been clear to someone who knew Latin and Greek. I endorse Cremastra's example: state the meaning of the components (with a source of course) and leave it to the reader to join the dots. (Botanists have it a bit easier in this respect, because Stearn's Botanical Latin has long lists of Latin and Greek components, and examples of combinations.) Peter coxhead (talk) 17:20, 28 November 2024 (UTC)

I agree. I have read (and cited) entire academic articles written in Latin (the abstract is often in the vernacular, often not English). Latin scholarly articles are surprisingly easy to read, written in a Latin that favours academic terms with close loanword cognates in many languages, and avoiding elaborate syntax, like the Simple English Wikipedia does. They are much easier to read than Latin texts written by native speakers like Julius Caesar.

Per WP:NONENG and WP:TRANSCRIPTION, sources need not be in English, and it is not WP:Original research to translate information (it's just another way of paraphrasing what the source says). I once wrote an article where almost none of the sources were in English, software package listings excepted. If you are confident that you understand the language, you can write a translation. Frankly, scientific names are assembled out of components, and the meaning of the compound in natural language is pretty much irrelevant, so translating the components is better anyway. I'd favour linking both of them to Wiktionary, alongside a (cited) discussion of the characteristic softbelliedness of the crabs, as you did in your first post. HLHJ (talk) 03:55, 30 November 2024 (UTC)

There's a name for doing this in linguistics: Wiktionary:surface analysis. It is contrasted with diachronic etymology, where you look historically to find out how the word originally formed. HLHJ (talk) 03:13, 2 December 2024 (UTC)

Category:Endangered species by reason they are threatened has been nominated for discussion

Category:Endangered species by reason they are threatened has been nominated for possible deletion, merging, or renaming.

If you would like to participate in the discussion, you are invited to add your comments at the category's entry on the categories for discussion page. Thank you.

About 70 subcategories, the oldest from 2015, are also being proposed for deletion.

These categories are used for extinct species as well as living ones.

There is debate about whether it is possible to list some threats to a species without oversimplification and omissions amounting to misinformation; comments from anyone with an interest in threatened species or extinction would be particularly welcome. HLHJ (talk) 04:47, 17 November 2024 (UTC)

Automated taxonavigation in Commons

Is there any way that we could replicate the automatic taxobox system for the taxonavigations in Wikimedia Commons? It takes excruciatingly long to update the taxonavigation box for every taxon. — Snoteleks (talk) 22:56, 22 November 2024 (UTC)

In principle, yes. Commons could have its own equivalent of our taxonomy templates, and use these to construct taxonavigation boxes, or Commons could use our taxonomy templates. However, that would be a decision to be made over at Commons, not here. (A major problem would be that individual language Wikipedias don't agree on taxonomy, which is why taxonavigation boxes can be inconsistent.) Peter coxhead (talk) 08:27, 23 November 2024 (UTC)

I don't think that the issue is that they don't agree on taxonomy, I believe that the English Wikipedia just happens to be better maintained sourced. If there were automatic taxonavigations boxes at Commons, they would just try to represent the most recent literature and consensus, just like automatic taxoboxes. (Also, Wikidata also gives the same taxonomy for all languages). I don't really know who I should ask about this topic at Commons, though, since I couldn't find anything similar to the ToL WikiProject. — Snoteleks (talk) 10:21, 23 November 2024 (UTC)

Wikidata also gives the same taxonomy for all languages – Wikidata allows multiple values for the parent of a taxon, so doesn't represent a single taxonomy. Wikidata gives the same taxonomies (plural) for all languages. Look at Lemnaceae (Q14293890) – a taxon we don't recognize in the English Wikipedia. For us, the parent of Lemna (Q161207) is Lemnoideae, not Lemnaceae. The equivalent for Commons would be multiple taxonavigation templates. Peter coxhead (talk) 10:33, 23 November 2024 (UTC)

That just means that either Wikidata or English Wikipedia is not accurate and needs to be updated. I do not see that as differing opinions. — Snoteleks (talk) 21:21, 23 November 2024 (UTC)

@Snoteleks: within limits, taxonomy has a subjective component. The rank at which to recognize a group can certainly be a matter of opinion. Some sources, such as PoWO, are known 'lumpers'; regional floras and specialists are more likely to be 'splitters'. If you want to see an extreme example, see Blechnum. We chose to go with PPG I, others could perfectly legitimately choose to go with PoWO. Neither approach is "accurate" or "inaccurate". Peter coxhead (talk) 22:27, 23 November 2024 (UTC)

The scientific consensus is one thing, and at Wikipedia we try to follow it because it is backed by credible sources. The databases (such as PoWO) are a completely different thing, they are subjective because they are maintained by specific individuals who usually don't keep the data completely up to date with the literature. Moreover, databases are based off of the scientific literature, not the other way around. This means that the taxonomy based on the former is by definition accurate, while the taxonomy based on the latter is inaccurate. — Snoteleks (talk) 23:29, 23 November 2024 (UTC)

@Snoteleks: two quick points: don't assume there is always a consensus; we are supposed to use secondary or tertiary sources, not primary ones – we mustn't try to judge consensus from the literature. Anyway, no more from me on this subject. Peter coxhead (talk) 15:45, 24 November 2024 (UTC)

@Snoteleks: Commons does actually have its own TOL WikiProject, but I don't think it's active anymore. (Nor has it been for a few years now I think.) Monster Iestyn (talk) 18:07, 23 November 2024 (UTC)

What actually happened is that a previous edit not by me changed the wikitext of my ping from @[[User:Snoteleks|Snoteleks]] to @[[User:|Snoteleks]] and so breaking it, probably unintentionally? Monster Iestyn (talk) 22:49, 24 November 2024 (UTC)

I'm not sure I understand what you are asking. Commons has Commons:Template:Taxonavigation, which produces the top navigation bar using manually entered parameters, and Commons:Template:Wikidata infobox, which produces the "taxobox" using wikidata. If you want Taxonavigation to automatically fill in the taxa, perhaps you should ask at Commons:Template:Wikidata infobox. They already have code for automating the taxonomy in the taxobox, so someone might be willing to modify that for Commons:Template:Taxonavigation.  —  Jts1882 | talk  12:27, 23 November 2024 (UTC)

Just to note that if you use Commons:Template:Wikidata infobox on a taxon which has multiple parent values set in Wikidata, the template uses the first one. So if there were a Wikidata infobox on Commons with |qid=14293890 (Lemnaceae), it would (currently) show the parent as Arales, as this is the first listed parent. Peter coxhead (talk) 13:46, 23 November 2024 (UTC)

In that particular case there is a preferred parent, which the infobox should be able to select (yet doesn't). But in most cases where there are many they are all left as normal (neither deprecated or preferred). In some cases they include immediate parents and others that skip straight to a higher rank. Unfortunately, as the statements are usually in order they are added, old relationships will be selected over the new ones. There is no solution, as Wikidata is set up, as even if people tried to set preferred values, different wikipedia might want different systems (e.g. POWO v World Ferns).  —  Jts1882 | talk  17:05, 23 November 2024 (UTC)

Sadly we regularly come to the conclusion that nothing can be done because of the way that Wikidata is set up. Peter coxhead (talk) 15:45, 24 November 2024 (UTC)

Discussion about Taxonbar on Wikispecies

I have started a discussion on Wikispecies regarding the Taxonbar template. In the past (in 2020) it was banned for use on Wikispecies mainly due to problems with its design with respect to what Wikispecies actually does as opposed for example Wikipedia. I have made some suggestions that are more in keeping with the function of Wikispecies in the hope we may be able to get it approved for use and would appreciate any feedback from people here who may be interested in this. Thanks. Scott Thomson (Faendalimas) ^talk 15:08, 24 November 2024 (UTC)

Taxobox images and image_alt parameters

While working on other ToL matters, I became aware that in various taxon articles with one or more images in the (manual or automatic) taxobox, these images either entirely lack a |image_alt= parameter, or have it left blank. (Going to be honest: I'm fairly sure I've been guilty of that myself as well!)

To get a rough idea of the scale of these absent/blank image_alt parameters, I spot-checked various articles transcluding the three main taxobox templates—{{Speciesbox}}, {{Automatic taxobox}} and {{Taxobox}}—until I found 20 of each with at least one image using the |image= parameter or a numbered equivalent.

Out of these sixty articles, only seven consistently provided image_alt parameters, and another two did so partially.

Assuming these results are roughly representative of taxon articles as a whole, ~88% of taxon articles with infobox images lack alt text for some or all of these. That is, well, not good, considering that per the MOS and Accessibility guidelines, such images should have one. (I wrote up a quick summary of these guidelines within the context of taxoboxes, which can be found here, if anyone prefers that).

I intend to add this missing alt text where I come across it, but the presumed scale of the issue combined with the size of ToL means I cannot feasibly do it alone. Anyone else willing to help, whether that's by looking for articles with missing alt text or "just" checking whether there's alt text for infobox images on articles you're already working on anyway, would be much appreciated. AddWittyNameHere 09:23, 30 November 2024 (UTC)

We could use |image_caption= to populate |image_alt= when it is absent. Not all taxobox images have captions, but when they do that would be useful. And in the absence of the either, we could put the file name. While sometimes confusing, this would usually be better than nothing. So in {{speciesbox}}, we could change:

• Current (line 79): | image_alt = {{{image alt|{{{image_alt|}}} }}}
• Using caption: | image_alt = {{{image alt|{{{image_alt|{{{image caption|{{{image_caption|}}} }}} }}} }}}
• And using file name: | image_alt = {{{image alt|{{{image_alt|{{{image caption|{{{image_caption|{{{image|}}} }}} }}} }}} }}}

Is there a downside I'm missing? This wouldn't be a substitute for encouraging use of |image_alt=.  —  Jts1882 | talk  10:10, 30 November 2024 (UTC)

On reflection, an obvious downside is wikitext in the caption. This could be stripped with a simple function, but does make the change less trivial.  —  Jts1882 | talk  10:13, 30 November 2024 (UTC)

If stripping the wikitext from the caption is possible, it could be a decent if flawed stop-gap measure in those cases where captions are present and alt text is not. (Which, based on my sampling, would be over half of cases with missing image_alt). I do imagine, though, that the same text getting read out twice by a screen reader, once as alt text and again as caption, might also be rather frustrating (if probably still an improvement over no alt text). Would there be a way for the template to automatically detect if a caption is present, and if so, populate image_alt with "refer to caption"? I could see that being a better solution, if feasible.

As for using the file name, my understanding is that one of the reasons for using alt text is because screen readers will otherwise default to reading out the file name, which is considered unwanted and potentially confusing. Not sure that actively populating image_alt with the file name is an improvement when the behavior is likely to remain identical but with additional steps behind the screens.

(That said, that's based on what little of the technical side of templates and alt text I understand, and I could be wrong there. As far as technical downsides go, I'm not the one to ask, really. I can use templates and follow the documentation of parameters, but creating/editing them beyond the most basic level is beyond me, I'm afraid.)

(edit conflict) [I hadn't read your addition when I posted the following]

On reading MOS:ALT, it seems repeating the caption is discouraged. Instead, adding |image_alt=refer to caption might be more appropriate when there is a caption and no alt text provided. Also it says screen readers will read the file name which can be confusing and is one reason alt text is required  —  Jts1882 | talk  11:17, 30 November 2024 (UTC)

Seems we had practically-identical thoughts at the same time, then. AddWittyNameHere 11:20, 30 November 2024 (UTC)

Something like this might do:

• | image_alt = {{{image alt|{{{image_alt|{{#if:{{{image caption|{{{image_caption}}} }}}|refer to caption| }} }}} }}}

The syntax of the #if statement needs checking. It could be added to {{taxobox/core}} but that tends to need more checking  —  Jts1882 | talk  11:28, 30 November 2024 (UTC)

Okay! Not sure how to best go about checking it, so I'll leave that to you and/or others with actual syntax and syntax checking knowledge. Still, it sounds like it should be feasible then, just checking whether this is the correct syntax to do it? If so, that's good news and would significantly reduce the scale of the problem for the moment. (Would still be good if those image_alts eventually get populated by actual manual alt text, of course, but certainly of lower priority than stuff that has neither caption nor alt text)

I should probably also look into how to get a list of all articles that use a taxobox of some kind, have a non-blank image parameter, and lack an accompanying image_alt or image_caption parameter and/or have a blank one. Guess I'll do that after I get some much-needed sleep, though. AddWittyNameHere 11:43, 30 November 2024 (UTC)

I did a test with {{speciesbox}} in the edit preview and it looks like it worked. It's probably best to put it in a utility template, say {{taxobox/alt_text}}, so it can be added in several places, as {{taxobox/core}} handles six images (2 images and 4 range maps).

My searches suggest the number of taxoboxes with |image_alt= is only a few percent, assuming this search is what I intended it to be. About 1500 uses of |image_alt= in about 140,000 speciesboxes with images and 40,000 with captions.  —  Jts1882 | talk  11:54, 30 November 2024 (UTC)

Would it work as-is in several places? I'd think that as currently written, if added to one of those other places, it'd end up looking for whether the first image--not the one it actually applies to--has a caption, since the caption parameter names aren't the exact same for image2 and the range maps. Could be wrong though, definitely am not a syntax expert. AddWittyNameHere 12:13, 30 November 2024 (UTC)

1624 Speciesboxes have |image_alt= in the Template Parameters report. Plantdrew (talk) 16:36, 30 November 2024 (UTC)

Okay, thank you! Seems fairly close to what Jts1882's search indicated, then. Might be worth eventually figuring out where the difference is, but for now, using Jts1882's search except slapping a - in front of the portion used to look for image alt should get me the majority of speciesboxes with images but without |image_alt=, I think. Can always look for a more exact search to catch the stragglers if we ever get the bulk dealt with, but not super worried over missing a couple hundred or getting a hundred or so show up that do have alt text on a six-digit total...

PetScan question

I'd like to perform PetScan searches using the "categories" of the WikiProject quality/importance table. For example, sorting by size the lichen task force articles that are "stub" & "mid"-importance. Is such a thing possible with PetScan (or any other tools)? If it is, what do I enter in the "Categories" box? Esculenta (talk) 17:13, 13 December 2024 (UTC)

@Esculenta: I don't think you can do exactly what you want. Go to PetScan and put "Stub-Class Lichen task force articles" and "Mid-importance Lichen task force articles", without the quotes, on separate lines in the Categories box, with Combination set to Intersection. Then move to the "Page properties" tab and tick the "Talk" box – this is important because by default PetScan only finds articles in mainspace; without this box ticked you get 0 returned. Then click "Do it!". I got 684 results. BUT this won't tell you the size of the articles, only the size of the talk pages. The problem is that the class/importance categories are on the talk pages, not the articles. Peter coxhead (talk) 19:17, 13 December 2024 (UTC)

Link to the search described above Peter coxhead (talk) 19:19, 13 December 2024 (UTC)

Thanks for trying; looks like I'll have to write a script to get these results. Esculenta (talk) 19:30, 13 December 2024 (UTC)

Yeah, PetScan can be used to search talk page categories, but then you only get properties (e.g. size in bytes) of the talk pages, not of the articles themselves. I guess you could do it in multiple steps; Petscan the talk pages you're interested in, copy those results into a text editor, and do a find/replace to turn the links to the talk pages into links to articles. Then copy the text with the links to the articles onto a Wikipedia page (a sandbox of yours) and do a Petscan for "Linked from" with your sandbox page as the page they are linked from.
