Synecology – Niche Differentiation
Notes for a Short Course: Studies in Geology, 1980Crinozoans and Blastozoans typically occur in very diverse epifaunal suspension feeding communities. In Lower Mississippian rocks of Indiana, as many of 155 benthonic invertebrate species lived in a single community (Ausich, Kammer, & Lane, 1979; Lane, 1973, Ausich & Lane, 1980). How did so many species co-exist? According to current ecological

The importance of niche differentiation for coexistence on large scales
Journal of Theoretical Biology, 2011It is widely accepted that niche differentiation plays a key role in coexistence on relatively small scales. With regard to a large community scale, the recently propounded neutral theory suggests that species abundances are more influenced by history and chance than they are by interspecies competition.

Niche Differentiation in a Primate Community
1980The six monkey and ape species in the Krau Game Reserve comprise a primate community, in the ecological rather than sociological sense, together filling the diurnal primate niche in this particular rain-forest. Between them they carve up the primate ‘cake’ into uneven slices according to the particular characteristics and requirements of each species ...

Stromal niches, plasma cell differentiation and survival
Current Opinion in Immunology, 2006Contacts made with other cells and stroma have a major impact on proliferation, differentiation, survival, migration and immunoglobulin class switching of plasma cell precursors as well as on the lifespan of the antibody-secreting cells. Induction of tissue-specific chemokine receptors and adhesion molecules directs migratory plasma cell precursors to ...

On testing temporal niche differentiation in carabid beetles
Oecologia, 1989It is first shown that den Boer's (1985) claims that competition should be rejected as a factor explaining community structure are not warranted by his tests on temporal niche differentiation in carabid beetles. The power of these tests is so low that they are unlikely to detect even the most extreme pattern of niche differentiation.

Competition and the niche; limiting similarity and differential niche overlap
1984In the previous chapter, competition was shown to influence both the size of the niche and the degree of niche overlap between species. The ideas discussed there lead to an interesting question. If no two species can occupy the same niche indefinitely when resources are limiting, then how similar can two species be and still coexist?

Competition, facilitation, and niche differentiation in two foliar pathogens
Oecologia, 2005We studied competition between the obligate biotroph Puccinia triticina (designated here as Puccinia) and the facultative saprophyte Pyrenophora tritici-repentis (designated here as Pyrenophora) in older and younger leaves in a set of three host genotypes selected to be resistant to Puccinia only, Pyrenophora only, or neither. Age-related resistance is

Differential Niche Utilization in a Grassland Sparrow
Ecology, 1971Henslow's Sparrow (Ammospiza henslowii) is a secondary sexually monomorphic breeding bird in meadows, hayfields, prairies, grasslands, and some croplands in eastern North America. Foraging behavior during the nestling period involved no intersexual differences in prey selection, and both sexes were opportunistic in food choice.

Competition and Niche Differentiation in Bumblebee Communities
2009Abstract There are about 250 species of bumblebee worldwide, mostly distributed through the temperate, alpine and arctic regions of the northern hemisphere (Williams 1989a).In most communities, several different species of bumblebee occur sympatrically (Ranta and Vepsäläinen 1981; Williams 1989b).
