ah! any leading space on the left margin converts to ugly-font (whatever the technical term is). What you want are multiple asterisk for different bullets. ---
The new entry on Ecoregions updates the science of this entry. Biome may not be a technical term in ecology any more - or may describe the large ecological zones roughly equivalent to the continents. Source check required.
- If it's WWF ecoregions you are talking about, they tesselate neatly into the superset of WWF biomes (not the same as realms). The map from WWF is just one biome map, but its being used quite widely for global ecological analysis, I suspect because it 'feels' right and because its' freely available. --Flit 22:03, 25 November 2005 (UTC)

Replace climax with steady state
Because climax is an obsolete term, I propose replacing the following:
In ecology, a biome is a major regional group of distinctive plant and animal communities best adapted to the region's physical natural environment, latitude, altitude and terrain factors. A biome is composed of the climax vegetation and all associated subclimax, or degraded, vegetation, fauna and soils, but which can often be identified by association with the climax vegetation type.
In ecology, a biome is a major ... regional group of distinctive plant, and animal communities best adapted to the region's physical natural environment, latitude, altitude and terrain factors. A biome is composed of communities at stable steady state and all associated transitional, disturbed, or degraded, vegetation, fauna and soils, but can often be identified by the steady state vegetation type.
I am assuming here that biome remains a useful, technically valid, term. If not, it is best to revise the current wording differently than I have suggested. -- Paleorthid 13:35, 12 April 2006 (UTC)

Biomes vs. Ecozones
The ecozone page explains it -- biomes are about similar kinds of landscapes and habitats regardless of the specific plant and animal species, while ecozones distinguish between different species and evolutionary history (the study of biogeography). Pfly 23:19, 8 April 2007 (UTC)
Order of Biomes
Now, I'm no oceanographer, but judging from the Riparian zone article, it appears to me that it more properly belongs in the Terrestrial biomes category, rather than Aquatic biomes. Can you explain why you listed it there?
Also, I think it would be useful to list the various biomes in some kind of order. Of course, it's possible that you did and I just don't know enough about it to recognize the order!
I'm interested in hearing your thoughts! Thanks for creating a LOVELY template! ~ Mpwrmnt 08:09, 12 January 2007 (UTC)
- Can someone explain this? It could probably be put in the article, also, the answer. KP Botany 15:01, 12 January 2007 (UTC)
What's a BIOME??
I think the standard answer is:
Ref: Olson, David M. et al. (2001); Terrestrial Ecoregions of the World: A New Map of Life on Earth.
Ref: Ecoregion World Wildlife Fund (Content Partner); Cutler J. Cleveland (Topic Editor). 2008. "Ecoregion." In: Encyclopedia of Earth. Eds. Cutler J. Cleveland (Washington, D.C.: Environmental Information Coalition, National Council for Science and the Environment).
I think this paper and this page should guide the whole link tree of the Ecology portal, 14 Terrestrial Biomes, 8 Biografical Realms and 867 Ecoregions. Riparian zone is not one of the Terrestrial Biomes on this list, it is never dry. The colours of the map should be used as guide for the template as well. I tried a compromise at the portuguese version, not great yet. Flooded Grasslands and Savannas was missing ("Chaco", "Pantanal"). --Chris.urs-o (talk) 13:17, 16 January 2009 (UTC)
The new Biome template got more Terrestrial Biomes:
-. Taiga/boreal forests
-. Montane grasslands and shrublands
-. Temperate coniferous forests
-. Tropical and subtropical coniferous forests
-. Temperate broadleaf and mixed forests
-. Mediterranean forests, woodlands, and shrub
-. Tropical and subtropical moist broadleaf forests
-. Tropical and subtropical dry broadleaf forests
-. Temperate grasslands, savannas, and shrublands
-. Tropical and subtropical grasslands, savannas, and shrublands
-. Deserts and xeric shrublands
-. Flooded grasslands and savannas
-. Littoral/intertidal zone
-. Mangrove forests
-. Kelp forest
-. Coral reef
-. Neritic zone
-. Continental shelf
-. Pelagic zone
-. Benthic zone
-. Hydrothermal vents
-. Cold seeps
-. Pack ice
There is an Hierarchy: Earth - Ecozone/ Biome (Major Habitat Type!!!) - Bioregion - Habitat
Riparian, Wetland, Littoral/intertidal zone, Kelp forest, Pack ice, Pond are Habitats of a Bioregion with its inhomogeneity, and a Bioregion of a Biome and a Ecozone !!! --Chris.urs-o (talk) 22:11, 31 January 2009 (UTC)

WWF "Major Habitat Types"
I can't find anything (in this article or elsewhere) on what criteria are used to define the WWF's "major habitat types" (biomes), or what other classification system it's based on. —Pengo 03:36, 13 March 2007 (UTC)
- The book Terrestrial Ecoregions of North America says on pp. 12-13 that the WWF grouped their ecoregions "into ten major habitat types (MHTs), following a global framework applied in other regional analyses (Dinerstein et al. 1995; Olson and Dinerstein 1998)." And that "MHTs are not geographically defined units; rather, they refer to the dynamics of ecological systems and to the broad vegetative structures and patterns of species diversity that define them. In this way they are roughly equivalent to biomes." The sources cited in full are:
- Olson, D.M., and E. Dinerstein. 1998. The Global 200: A representation approach to conserving the earth's most biologically valuable ecoregions. Conservation Biology 3:502-515.
- Dinerstein, E., D.M. Olson, D.J. Graham, A.L. Webster, S.A. Primm, M.P. Bookbinder, and G. Ledec. 1995. A conservation assessment of the terrestrial ecoregions of Latin America and the Caribbean. Washington, DC: World Bank.

Can we consider revising and reintroducing the biome template that I created some time ago? I think that it would be useful to have some sort of way of navigating through the various biomes. I know that I rather briskly introduced it beforehand, but I feel that with some improvement, it could really work (I know it’s rather massive!) Cheers! Max Naylor 19:39, 2 April 2007 (UTC)
I'm thinking of editing the introduction, but thought I'd post about it here first.
One of the issues is the way the word biome is defined (even in many textbooks) as a large regional grouping based on specific plants and animals (or biota). But biomes are not, strictly speaking, based on biota, as just about any global biome map shows, like this one, a quick find via google. A biome like "temperate deciduous forest" occurs on most continents, as that map shows, but the biota of any given biome is quite different on different continents. Australian forests have Agathis (kauri) trees, for example, while South America has Fitzroya (alerce), and North America has Douglas-fir. Europe has none of these. Terms like biota and "plant community" are based on specific species and groups of species, if I understand it right.
Wouldn't it be useful to point out something about how biomes are not based on specific plants or communities but rather on "ecologically similar" biota that are "not necessarily related taxonomically"? Some definitions do make this point -- like here and here. Others don't, like here, which seems to confuse biomes and ecozones ("biogeographic kingdoms" on that page).
A glossary in a WWF book I have defines biota as "the combined flora, fauna, and microorganisms of a given region"; and, in contrast, guild as "..group of organisms, not necessarily taxomonically related, .. [but] ecologically similar in .. diet, behavior, ... or with regard to their ecological role in general". They use the term "major habitat type" (MHT) instead of biome, saying that MHTs are "roughly equivalent to biomes." The glossary defines MHT as a set of ecoregions that are similar in several ways; 1) similar climate; 2) similar vegetation structure; 3) similar biodiversity patterns; and 4) flora and fauna with similar guild structures and life histories." The use of the term guild in place of biota seems significant.
Anyway, I was thinking of trying to rewrite the introduction to make this kind of stuff clearer. As it is now, it is hard to tell why biomes are not more like ecozones -- which are based on biota, distinguishing Australia from North America.
This brings up another issue with the introduction. If the stuff I wrote above is true, then biomes are not based on regional or geographic patterns. Once defined and mapped, biomes show geographic patterns, but isn't that a effect rather than a cause of defining biomes? And if so, then it is not quite accurate to say that biomes are "subdivided into ecoregions", as I've often seen. Rather, ecoregions are defined by various factors including geographic ones, resulting in a bounded region. Ecoregions are assigned to a biome (or MHT). As a result, you can make a map of biomes, but the geographic boundaries come from the ecoregion definitions and not the biome -- at least in the WWF system, which seems to be the main one used on wikipedia. There are probably other systems that do define biomes geographically and then subdivide them.
My thought is to try to condense this long babble I just wrote into something short and simple to use in the introduction. Perhaps something about the meaning of "biome" in a very general sense, then a mention of example systems, including the WWF's system, which can then be explained in more detail in its own section. Many other pages could use clarification along these lines, it seems to me.
Does this all make sense? Sorry for the lengthy text. Pfly 21:17, 10 April 2007 (UTC)
WWF definitions seems to be: 867 Ecoregions of the Earth are assigned to one of 14 biomes (or "major habitat type", MHT)and one of 8 Biogeografical Realms. --Chris.urs-o (talk) 13:28, 16 January 2009 (UTC)
The first sentence in the intro is incorrect as it is: "A biome is a climatically and geographically defined area of ecologically similar climatic conditions such as communities of plants, animals, and soil organisms,  and are often referred to as ecosystems." This basically equates conditions to communities and animals. Animals are not a condition. I can't think of suitable words at the moment. —Preceding unsigned comment added by Duboshi (talk • contribs) 15:34, 16 February 2009 (UTC)
- Agree that this is a mess. The Campbell quote doesn't help, although I've seen it on multiple sites (what is "that environment"?) What seems to make sense is to distinguish "habitat types" from biomes. HT's are things like "grasslands" and "rain forests". Biomes are the things that live in particular habitats. I.e., not types. I.e., the biome of the Russian steppes is different from the biome of the American prairie. I.e., they are characterized by their inhabitants, not by the environment. The biomes that occupy a particular HT are interestingly comparable, but not the same. It may help to think about the human microbiome. The HT is "human body", but the MB is "things that live on/in Joe's body". This is conceptually crisp, but may not conform to common usage. In any event, an appropriate source is necessary to avoid OR. Lfstevens (talk) 07:03, 14 September 2015 (UTC)
Material moved from "Organism"
The following material on biomes appeared inappropriately in the article on organisms, and I have therefore removed it from there.
Spatial relationships and subdivisions of land
Ecosystems are not isolated from each other, but are interrelated. For example, water may circulate between ecosystems by the means of a river or ocean current. Water itself, as a liquid medium, even defines ecosystems. Some species, such as salmon or freshwater eels move between marine systems and fresh-water systems. These relationships between the ecosystems lead to the concept of a biome.
A biome is a homogeneous ecological formation that exists over a large region as tundra or steppes. The biosphere comprises all of the Earth's biomes -- the entirety of places where life is possible -- from the highest mountains to the depths of the oceans.
Biomes correspond rather well to subdivisions distributed along the latitudes, from the equator towards the poles, with differences based on to the physical environment (for example, oceans or mountain ranges) and to the climate. Their variation is generally related to the distribution of species according to their ability to tolerate temperature and/or dryness. For example, one may find photosynthetic algae only in the photic part of the ocean (where light penetrates), while conifers are mostly found in mountains.
Though this is a simplification of more complicated scheme, latitude and altitude approximate a good representation of the distribution of biodiversity within the biosphere. Very generally, the richness of biodiversity (as well for animal than plant species) is decreasing most rapidly near the equator (as in Brazil) and less rapidly as one approaches the poles.
The biosphere may also be divided into ecozone, which are very well defined today and primarily follow the continental borders. The ecozones are themselves divided into ecoregions, though there is not agreement on their limits. Plantsurfer (talk) 14:31, 29 December 2007 (UTC)
A complete world map of the biomes would be helpfull. WWF has one to share []. But it is on geographic format (file type). I think all colours are present, check at map --Chris.urs-o (talk) 08:15, 5 February 2009 (UTC)

Problems in the lede
As currently written, the lead sentence—
Biomes are climatically and geographically defined as similar climatic conditions on the Earth, such as communities of plants, animals, and soil organisms, and are often referred to as ecosystems
— is nearly incomprehensible. I've taken a stab at simplifying it—
A biome is an area of ecologically similar climatic conditions hosting a community of living organisms
—but am not confident that my somewhat clearer wording isn't misleading in one or more important ways, so I'm not making the change yet.
Grammar and syntax aside, the lede should make clear the difference between a biome and an ecosystem; the "often referred to" wording is weaselly and needs to go. Either they're synonymous or they're not. If they're not, then substituting one term for the other would be inaccurate. (I think that a biome can comprise multiple ecosystems, but it has been a few years since I studied this stuff, so I'm a little fuzzy on the particulars.) If no experts (or cocky know-it-alls) wander by here soon, I'll post something at a relevant WikiProject page or maybe the Reference Desk. Rivertorch (talk) 20:37, 11 January 2011 (UTC)
you need to look after world biomes as they are dying very quickly.

Something strange about this sentence, "The Bailey system, based on climate, is divided into seven domains (polar, humid temperate, dry, humid, and humid tropical), with further divisions based on other climate characteristics (subarctic, warm temperate, hot temperate, and subtropical; marine and continental; lowland and mountain)."
