摘要:
Habitat fragmentation can alter the trophic structure of communities and environmental conditions, thus driving changes in biodiversity
Data from: How habitat-modifying organisms structure the food web of two coastal ecosystems

DOI:
doi:10.5061/dryad.22p7r
摘要:
The diversity and structure of ecosystems has been found to depend both on trophic interactions in food webs and on other species interactions suc
Data from: Pyramids of species richness: the determinants and distribution of species diversity across trophic levels

DOI:
doi:10.5061/dryad.ps0f0
摘要:
Generalities of food web structure have been identified for extant ecosystems. However, the trophic organization of ancient ecosystems is unresolved
