Isn't the place an organism lives its habitat? So what is the difference? 151.188.247.81 20:19, 5 March 2007 (UTC)CS

A habitat is like an organisms address, and a niche is like its occupation. Think of zebras and wildebeests grazing the same plain. They share the same habitat, but their niche is different - e.g. they eat different types of grass. As long as there is niche differentiation they can coexist. If this was not the case, the competitive exclusion principle would drive one to extinction. Richard001 07:05, 11 May 2007 (UTC)

I think relating niche to occupation is confusing. A niche is the range of conditions and resources an organism needs to survive, grow and reproduce. This is what Hutchinson says and it is what the first external link says. —Preceding unsigned comment added by 121.217.42.253 (talk) 07:57, 10 January 2010 (UTC)

Yes, well said. I just used that analogy from Campbell's Biology, but it's not a great one (perhaps forgivable given that it doesn't go into any detail on conditions and resources, unlike say Begon, Harper and Townsend). Richard001 (talk) 11:06, 2 March 2010 (UTC)

The photograph of the lichens and its caption seem to be misleading to me. They suggest that ecological niche is a matter of physical location, whereas it is actually a more abstract concept, which refers to the range of possible circumstances under which a species can thrive.

I was just looking at Britannica's article on this (which is a bit shorter) and they've pulled the same photo and descripiton from here. I check back here and we're still using this photo too, and I had a similar thought. They're occupying a different space on the rock, but how do we know it's a different niche? Perhaps they just arrived in different places and haven't had time to spread much. What is it about the area of the rock where one lichen is that makes it ecologically different from the area where the other one is living? I don't think this image is so great for illustrating this concept so I'm going to take it down, and hope that at least one person does some work on this important article pretty soon.

The opening sentence, "In ecology, a niche (pronounced /ˈniːʃ/ or /ˈnɪtʃ/)[1] is a term describing the relational position of a species or population in its ecosystem to each other; e.g. a dolphin could potentially be in another ecological niche from one that travels in a different pod if the members of these pods utilize significantly different food resources and foraging methods," is so bad that I don't know where to start to correct it. 1) It's atrociously ungrammatical. 2) It introduces a secondary concept (the diet variability among members of a species) instead of what should be the central concept (the species niche). —Preceding unsigned comment added by 132.208.65.106 (talk) 23:46, 3 August 2010 (UTC)

Repeats material, grabs concepts from nowhere and inserts them...looks like an undergraduate essay. Someone please fix it so that it makes sense, and professors please stop assigning wikipedia articles to your students....

 Niche is by its nature limited by its surroundings.  This looks like an attempt by environmentalists to hijack a term to argue that Neanderthals should have won the confrontation with modern humans.Rdbooker1 (talk) 00:26, 29 November 2014 (UTC)

Hello fellow Wikipedians,

I have just modified one external link on Ecological niche. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20160310144027/http://artifex.org/~ecoreaders/lit/Grinnell1917.pdf to http://artifex.org/~ecoreaders/lit/Grinnell1917.pdf

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

Y An editor has reviewed this edit and fixed any errors that were found.

• If you have discovered URLs which were erroneously considered dead by the bot, you can report them with this tool.
• If you found an error with any archives or the URLs themselves, you can fix them with this tool.

Cheers.—InternetArchiveBot (Report bug) 13:55, 22 January 2018 (UTC)

The content at Niche differentiation and Niche segregation overlap heavily with this article and might therefore best be merged here. Note that this proposal arose following discussion at Talk:Niche differentiation, but is now probably best discussed here in the context of a broader merge.

Support merge. Hopefully, the giant wall of text at Niche segregation can be broken up a bit. Joyous! | Talk 19:05, 19 February 2023 (UTC)

In American English, rhymes with "itch." 2601:1C1:8400:49D0:A86A:56C0:3B1:8ACC (talk) 14:00, 19 April 2023 (UTC)

I don't know too much about Wikipedia paragraph or section standards, but as someone who has used Wikipedia quite a lot, I don't think I've ever seen a literal wall of text with no paragraph breaks for one section. Can someone with more skill figure out how to break this down into less intimidating (and easier to read) paragraphs? 66.230.106.35 (talk) 19:55, 27 December 2024 (UTC)

The two paragraphs below seem to have little to do with the sort of resource partitioning being discussed. They certainly are not the best examples. Also, if for some reason this wasn't cut, the full binomial species name should be provided.:

"Research has determined that plants can recognize each other's root systems and differentiate between a clone, a plant grown from the same mother plants seeds, and other species. Based on the root secretions, also called exudates, plants can make this determination. The communication between plants starts with the secretions from plant roots into the rhizosphere. If another plant that is kin is entering this area the plant will take up exudates. The exudate, being several different compounds, will enter the plants root cell and attach to a receptor for that chemical halting growth of the root meristem in that direction, if the interaction is kin. Simonsen discusses how plants accomplish root communication with the addition of beneficial rhizobia and fungal networks and the potential for different genotypes of the kin plants, such as the legume M. Lupulina, and specific strains of nitrogen fixing bacteria and rhizomes can alter relationships between kin and non-kin competition. This means there could be specific subsets of genotypes in kin plants that selects well with specific strains that could outcompete other kin. What might seem like an instance in kin competition could just be different genotypes of organisms at play in the soil that increase the symbiotic efficiency."
