This is a WikiProject, a collaboration area and open group of editors dedicated to improving Wikipedia's coverage of a particular topic, or to organizing some internal Wikipedia process.
Please see the Guide to WikiProjects and the Directory of WikiProjects for more information.
First, an important note for everyone to remember:
A few Wikipedians have got together to make some suggestions about how we might organize data in these articles. These are only suggestions, things to give you focus and to get you going, and you shouldn't feel obligated in the least to follow them. But if you don't know what to write or where to begin, following the below guidelines may be helpful. Mainly, we just want you to write articles!
This WikiProject aims primarily to represent the taxonomy and relationships of living organisms, as well as their extinct relatives, in a tree structure. Since there are millions of species, not all will be included, but we aim to handle as many as information, time, and interest permit.
This WikiProject descends from WikiProject Biology. Various other WikiProjects may be based on it to better treat specific groups. Currently there are:
In cases where there is a formal common name (e.g. birds), or when common names are well-known and reasonably unique (e.g. "Cuvier's dwarf caiman"), they should be used for article titles. Scientific names should be used otherwise.
Note the following guidelines in using scientific names:
Names of genera are always italicized and capitalized–Homo, Rosa, Saccharomyces.
Species epithets are always italicized and preceded by the name of the genus or an abbreviation of it— Homo sapiens or H. sapiens, but never plain sapiens, since such identifiers need not be unique. They are never capitalized.
Names of higher taxa are capitalized but not italicized— Hominidae, Mammalia, Animalia.
In cases where a group only contains a single subgroup, the two should not be separated (unless the higher-ranked group has had multiple circumscriptions, and an article is written to cover them all). If there is no common name, the article should generally go under the scientific name that is most often used when discussing the group, or under the scientific name of lowest rank if there is no clear preference. However, for a genus that contains a single species, the genus name should be used since it is included in the binomial. For instance the order Amphionidacea, which has the single species Amphionides reynaudii, is discussed at Amphionides.
Not all species need have separate articles. The simplest (and probably best) rule is to have no rule: if you have the time and energy to write up some particularly obscure subspecies that most people have never even heard of, go for it! As a general guideline, though, it's best to combine separate species into a single entry whenever it seems likely that there won't be enough text to make more than a short, unsatisfying stub otherwise. If the entry grows large enough to deserve splitting, that can always be done later.
A useful heuristic is to create articles in a "downwards" order, that is, family articles first, then genus, then species. If you find that information is getting thin, or the family/genus is really small, just leave the species info inline in the family or genus article, don't try to force it down any further.
Common name capitalization
Many of the WikiProjects listed above have defined standards for the capitalization of common names, which should be used when discussing the groups they focus on. There is currently no common standard, so no particular system should be enforced overall.
Detailed taxonomic information, including notes on how taxa are defined and how they vary between different systems, belongs in the article proper. Where possible, however, a standard table will be provided to allow easier navigation between related groups and quick identification of what sort of organisms are being discussed. These are called taxoboxes. A typical taxobox is shown at right (it belongs on the top right of the page Cetacea).
There are three main sections to the taxobox:
A header showing the name of the group, sometimes followed by a representative image.
A table showing the placement of the group in a typical classification system.
A footer, whose content varies, showing the binomial name or a species, or a list of subgroups for higher taxa.
Some items that are often included, but are not (necessarily) standardized, include:
Position: The taxobox generally belongs at the top right corner of the article, unless it has been decided otherwise on the relevant talk page - for instance, if the article is not primarily about the biological group.
Major groups should be given their own categories. When possible, these should use the common name in the plural. In general, only articles about major subgroups should be added, and more specific articles should be included in subcategories. However, when there are only a few articles about members of the group, they can all go directly into the main category. Use your judgement on when to split, aiming for an approximate category size of 10-50 articles.
Note that in addition to taxa, categories may also contain informal subgroups. For instance Category:Primates may include an article or subcategory for monkeys, although they are not treated as a formal group. They may also include some other articles that pertain specifically to members of the group, although they are not about them.
Categories related to the biota of a region should should be based on the common grouping of that region used by zoological, botanical, mycological etc. publications. For example, if it is common to separate a region based on political boundaries (as in parts of Europe), categories should be separated by countries. If it is common to separate regions based on geographic features (such as New Guinea), categories should be separated by geographic region.
Taxonomic resources
The taxonomy of many groups is in a state of flux, and it is not always possible to find a single satisfactory classification, and we would be doing a great disservice by pretending otherwise. The best would be to try and find out what the current consensus is, if there is one, and make notes on variant systems. In this, the following resources may be helpful:
General taxonomy
NCBI database − attempts to incorporate phylogenetic and taxonomic knowledge from a variety of sources.
UC Berkeley: History of life through time − phylogenetic cladograms; many well-summarized groups with illustrations; many pages "under construction"; links to other useful sites
Paleobiology Database : taxonomic and distributional information about the entire fossil record of plants and animals.
Systema naturae − usually gives multiple breakdowns for groups, which is sometimes confusing but can be very useful.
www.itis.gov − an automated reference database of scientific and common names for species built within a working hierarchy. ITIS partners with Species 2000 to build the Catalog of Life. Covers a lot of ground, but is often incomplete or idiosyncratic. (Note domain used to be www.itis.usda.gov . Deleting the usda component may restore the link.
Species 2000 − a list of specific taxonomic (current) databases, covering contemporary and fossil organisms.
Animals
Vertebrata - Japanese language, but the structure's fine and the names are in Sciencese!)
FishBase - Huge database giving basic info on thousands of fish.
Avibase - database including all the world's bird species
CephBase - superb information about Cephalopod classification. Permission granted to use their images (see image:Orangeback_Squid.JPG for example
Lepidoptera and other species (mostly related to Lepidoptera, such as popular butterfly plants, etc.). Info collected from other sources, not sure how accurate it all is. Interesting note: he has a (open source) perl script generating range maps automatically from distribution text.
BugGuide.net--extensive resource on taxonomy and identification of North American arthropods. Experts in many fields visit and help with taxonomy.
Mesozoic mammals - Containing much information about Mesozoic mammals and relatives.
Fauna Europaea - Database of all European land and freshwater animals.
Plants
Angiosperm Phylogeny Group (2003). An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG II. Botanical Journal of the Linnean Society, 141, 399-436. available here : Available online. Probably now authoritative source for flowering plants at family level and above but already out of date for some groups; see next reference for more up-to-date information based on research since 2003.
The Missouri Botanical Garden is searchable by species, and where this is available, will give the accepted classification, and the degree to which it is accepted. Also lists authors, synonyms and homonyms. Far from complete.
Vascular Plant Families - a systematic and alphabetical index of the non-flowering and the flowering plant families with the Cronquist sytem and the phylogenetic system of Judd et al. (2002) (i.e. APG)
USDA/NRCS PLANTS Database - Not complete, but nice. Resource for some PD images, although not all are PD. Use Template:PLANTSDB to label images. Common names used are usually only common in the USA and may not be used worldwide.
HortiPlex Plant Database - Searchable by common or scientific name. Submitted by gardeners- may not be in line with current taxonomy.
ILDIS A database of legume taxonomy, includes synonyms and accepted names, common names and detailed bibliographies for many species.
Likewise, the following sites can help find taxonomic authors and abbreviations:
IPNI, authors search Note that the author database is separate from the plant name databases: the author database is authoritative. The plant name databases are "as is" and should be used as a search aid (invaluable as such) rather than as any kind of authority.
Fungi
Index Fungorum - database of fungus species, genus and higher names, with all historical synonyms and indication of current name
Stock.xchng - thousands of photos (e.g. over 9,000 in category 'animals', over 7,600 in category 'plants'), mostly free use ({{PD}}); many un-named, but a good source for those able to identify the pics
Requested photographs
If you wish to have a photo uploaded please add {{Reqphoto|animals}} on the talk page of the article. Category:Wikipedia requested photographs of animals lists these requests - if you can upload a photograph of any of these it would be appreciated.
Ba'Gamnan I am interested in Biology and in Photography.
Belizian I just take nature pictures in the Jungles of Belize, request welcome.
Bibliomaniac15 - I like and research organisms in general. However, why isn't there a WikiProject for Reptiles or Amphibians?
Bob the Wikipedian, a WikiDragon (talk) 03:20, 6 April 2008 (UTC): Going wherever my research takes me. For the record, I am starting with extinct prehistoric fishes. Don't ask me why!
EdWBaker Started WikiProject Phasmatodea. Mainly work with insects and gastropods
Elapied 10:44, 14 February 2007 (UTC) (earthworm taxonomy, mainly from South America, and also different invertebrate groups of marine life).
ElCharismo - I've always had a passion for taxonomy, and I'm very intrigued by this WikiProject. Here's to the proliferation of taxoboxes, untangling of reference roots, and healthy branching of the Tree of Life: Víva Biology!
Gangleri I arrived here because I saw that some Tree of Life articles, categories (maybe also lists) (also from other languages) are not linked to la.Wikipedia. Having Icelandic Sheepdogs I search dog related articles in other Wikipedias and link them together for the dog breeds project.
Iorsh Wild flora of Israel. I'm an amateur - most my contributions are stubs with taxobox and a photo.
Ingoolemo Currently mammals, will probably end up doing a lot of stuff on various organisms. I try to be as scientific as possible, but the problem is that taxonomy and biology aren't exactly the areas I specialise in.
Merovingian: I'm most interested in Bacteria, Archaea, Fungi, Protista, etc.
Miwa Primarily birds, but I'll Wiki-spackle just about anything where necessary.
Monk of The Highest Order I'm a bird man... na na na na na na... oh wait? Oh yeah, I just have a boxload of eastern north america bird books, so I'll be... processing the information onto wikipedia. If you know what I mean.
MPF Main interest in Pinophyta, also trees and other plants more generally
Phlebas Dinosaurs and fishes, mostly. Oh, and ostracods maybe too.
Princess Janay (talk) 21:30, 17 February 2008 (UTC)I already helped out. I created a much-requested biology article on The leaf is affected with Monochaetia fungi, a genus of Amphisphaeriaceae, a family of fungi.
Qwertzy2 Taxonomy of higher plants above all, but some small animals (crustaceans, insects or even birds) from time to time as well. No particular specialist knowledge.
Ram-Man Mostly for fish, but maybe some plants too.
Ravedave I plan on reviewing & helping all life articles that show up on FAC.
Richard Barlow - I've been working on moths for a while. Planning to do some butterfly stuff. Probably will dip into virtually anything! (Strictly layman - do NOT call me an entomologist!)
Sarefo - mostly spiders, also taxon work (genera pages etc., species lists), range maps.
Sabine's Sunbird - Birds, mostly, but I'll contribute to anything I know something about. Seabirds are my speciality.
Sambostock intend to standardise mammal pages. work on birds and everything else.
SB_Johnny I'm an organic farmer and horticulturist, interested in the practical side of plant articles.
Seglea I have some specialist knowledge on birds, rodents and primates (which need a lot of work), but I have ready access to the technical literature and am willing to turn an amateur hand to most taxa.
Sheep81 - Dinosaurs, mostly. Perhaps a few other articles here and there.
Shrumster - Ichthyologist by specialty, but I love animal systematics in general.
Shyamal - fauna and flora of the Indian subcontinent
Singing Badger, the No specialist knowledge but interested in improving stuff especially the prehistoric sections
Soo I seem to have become an accidental contributor to this project, but I thought I'd sign myself in anyway.
Spawn Man 22:48, 9 October 2005 (UTC) Happy to help the tree of life anytime!!
Stan Shebs fish, plants, insects, exotics - ideally material only in print previously, gives WP unique online content
Stanskis: Classification; Standard lists; Taxonomy in the service of Conservation and other uses. Broad background and dirty hands.
Superfo Ducks, primates, marsupials, etc, I'll do whatever I can... I love life!
Svartulfr1 Mostly interested in animals, particularly mammals. However, I am interested in all living creatures and will participate where I find the time and the interest.
Swid Add/clean up taxoboxes, add scholarly references, clean up/expand articles created about newly-described species.
Tannin Mostly birds and mammals, particularly Southern Hemisphere species.
TeunSpaans Mostly plants, perhaps occasional insects. Creating interwiki links, adding a hand at expanding some stubs.
Valich Phylogeny of Miacids (Miacoidae), Carnivora, some dog articles, "origin of life" topics, other articles as well
Visionholder Mostly involved in Primates, with a long-term goal of making all lemur articles GA-class or better. May also contribute to articles on any type of living or extinct creature.
Yummifruitbat Photos (my own) and content edits to pretty much anything; very slow translation of good articles from German wikipedia
Sample articles
A number of articles under this WikiProject and its descendants have been recognized for their excellence by the Wikipedia community as featured articles or featured lists, and may serve as good models. The articles are sorted by WikiProject:
To browse Tree of Life subjects that require articles, see the Requested articles sub-page for biology. If adding to the list of requests, make sure to include scientific names, as it will make it easier for others to track down information. One-sentence stubs are discouraged: try to create a worthwhile start class article, with a taxobox, and sources properly cited. When adding weblinks, look for standard references first, such as the IUCN and its sub-commissions.
Coelenterata currently redirects to Cnidaria, which is wrong, since this group acutally includes comb jellies too. There is a dispute with User:Dalbury, he reverts to redirect regardless arguments that this is a redirect from general concept to its subset. There is an article, but its extremely short, hardly a stub. Can someone with expertise in biology please create at least a 2-paragraph meaningful stub, or at least support my arguments that this redirect is confusing? --Maxxicum 02:00, 11 August 2006 (UTC)
Do you have a reference for that? I've been out of school for a while so I'm not up on the latest cladistics, but last I heard, Cnidaria and Ctenophora were coranked at the phylum level, placed in the subkingdom Radiata. Coelenerate was an outdated synonym. On scholar.google.com I can't find a reference to the infraphylum you suggest, although that's not necessarily gospel, obviously. tolweb.org also ranks them as sibling phyla, and that's how ITIS lists it, too. (see Template:TSN). --Grahamtalk/mail/ 07:37, 25 August 2006 (UTC)
Although it has been claimed on Talk:Coelenterata that Ctenophora was once treated as part of Coelenterata, that has to have been a while back. A 1965 textbook I have (Simpson and Beck. Life: an Introduction to Biology 2nd Ed.) lists 'Coelenterata or Cnidaria' and 'Ctenophora' as separate phyla under 'Metazoa'. Given the inherent conservatism of textbook writers, that is likely to have been the generally accepted classification for a while before 1965. -- ) 13:36, 25 August 2006 (UTC)
Species - This article needs to be reordered, citations added, sectioned and made more readable. I am sure we all agree that it is an important page for all Tree of Life projects. Shyamal 03:35, 14 December 2006 (UTC)
Kaziranga National Park- Can anyone create articles on the animals which have not been created till now in the Fauna part of the article? Pls help. 08:56, 3 April 2007 (UTC)
Ediacaran biota - I've just re-written this page on the 'roots of the tree' and would welcome any constructive criticism or improvements! Verisimilus 11:41, 10 April 2007 (UTC)
