Species niche |
Specie's place in nature... How do you measure a place in nature? An N dimensional hypervolume defined by a species environmental tolerances and resource requirements Environmental tolerances- temperature, salinity, shade (physical environment) Resource requirements- food items, drinking water, nest site- things environment must provide for organisms to provide |
|
|
niche space |
2 niche axis = area 3 niche axis= volume 4= 4D hypervolume |
|
|

2 species can't occupy same niche- 1 outcompetes. Gause's principle of competitive exclusion when species compete for essential resources that are in short supply, competitive exclusion occurs. |
|
|
Interspecific and Intraspecific |
Interspecific- individuals different species competing with each other (range of intensities) Intraspecific- Individuals of same species competing with each other (intense when resources limited) |
|
|
