Ecological Niche

Postby BiologicalParadox » Sun Jul 31, 2011 4:35 am

Could someone please explain to me what this is, I have found multiple definitions, some conflicting. I would also love to know how to use it in a sentence.
Thanks in advance. :)

Niche is where species or population is in its ecosystem. In lesser term, how they make a living. There are diffrent dimensions of a niche that has a wide variety of aspects of the environment which must be considered.

• 3 sets of parameters:

I.Range of physical factors for survival and reproduction: temperature, humidity, pH, soil, sunlight, etc.

II. Biological factors: predators, prey, parasites, competitors, etc.

III. Behavior: seasonality, diurnal patterns, movement, social organization, etc.

Example: Bristlecone pines - They are only adaptive alone the treeline of snow-cap mountains. Another is the Devils Pud fish in Nevada. Thermophiles too are great example of niche.

Hope this helps.

An ecological niche is the role an organism plays in a community in terms of the habitat it occupies, e.g., both a wolf and the wolf spider are predators. So they occupy the same ecological niche, albeit in a different habitat (even though they can live together in the same area, the habitat of the spider is of course much smaller than that of the wolf). While the lynx and the wolf could occupy the same ecological niche, which means they then would have to compete for the same resources (prey). So there can be ecological niches such as: predator, herbivore, detrivore, etc.

Niche is usually defined as a way organism lives its life.

The definition I like is from http://www.nps.gov/glba/forteachers/marine-environment-instructional-resources.htm
Ecological Niche - The way a species 'makes its living;' where it lives, what it consumes, and how it avoids consumption by predators or displacement by other species.
; however, for completeness I would also include procreate.

while searching for the source of this definition, I came across this http://www.montana.edu/screel/Webpages/Bio%20303/Biol%20303%20niches.pdf

From Mitchell, Paul; Ecology, 101 Key Ideas; NTC Publishing Group; Chicago, IL; 2000; p069
“There is no such thing as the ecological niche, there are at least three current, and quite different, uses of this abstract and enigmatic concept.
