We also see niche differentiation between Homo and Paranthropus-it looks probable that Paranthropus boisei had a relatively restricted diet, while members of the genus Homo were eating a wider variety of things.
The overall goal of the project is to obtain a comprehensive understanding of the diversity and ecophysiology of sulfur bacteria in soda lakes, their niche differentiation, and the molecular mechanisms by which they adapt to extreme halo-alkaline conditions.
Niche differentiation and niche conservatism give different predictions about the congruence of evolutionary relationship (as demonstrated by phylogeny) and ecological relationship (as demonstrated by co-occurrence within a habitat).
If niche differentiation is an important part of the speciation process in plants, we expect to see divergence between sister-species pairs on at least one niche axis (sensu Hutchinson, 1957) if they both continue to occupy the same region.
Using this hypothesis and previous work, we illustrate both niche conservatism and niche differentiation at different temporal and spatial scales within the tribe, and suggest directions for further research integrating ecological and phylogenetic data to study the evolution of diversity.
The Core Carex clade, with many strongly supported branches of closely related species, is used to illustrate the concepts of niche conservatism and niche differentiation.
Niche differentiation or niche segregation along environmental gradients is expected to evolve among closely related species as part of the speciation process (Levin, 2004).
