BIOL 2335 Lecture Notes - Lecture 16: Niche Differentiation
Document Summary
Community (local species pool) biotic factors (species interactions) . Various factors that affect or filter out diversity and the order in which they occur. Factors that affect species diversity in order are: none of the above, abiotic factors, abundance, species interactions, dispersal, abiotic factors, abundance, species interactions, abiotic factors, resource range, dispersal, abiotic factors, niche overlap (should be species interactions) Increasing niche overlap: not increasing niche breadth, not increasing environmental harshness decreases diversity by making it harder for other organisms to survive in the environment. Pool dispersal, abiotic factors interactions in pool. Niche making resources larger (more resources) we can add more species into the environment. If we overlap niches, there can be more species. Birds often eat same thing, but partition resources according to where they forage, particularly how high in canopy and how far out on the branches. You observe large range in bird species diversity.
