Community Structure and Trophic Level Interactions in the Terrestrial Ecosystems: A Review
Organisms have their own patterns of distribution and biological organizations functioning in the natural system. Community is one of the hierarchies of ecological organizations composed of different species of organisms interacting in space and time. Photosynthesis is the fundamental biological process by which radiant energy is converted to chemical energy and thereby readily becomes availabl...

متن کاملLinking size-based and trophic analyses of benthic community structure
Models of biomass size spectra assume that organisms with higher body mass feed at higher trophic levels, but explicit empirical tests of this pattern are rare. We used nitrogen stable isotopes (δ15N) as an index of the trophic level in a benthic fish and invertebrate size-spectrum, and demonstrated that body mass was positively and significantly related to trophic level. This pattern was consi...
متن کاملTrophic cascades in a complex terrestrial community.
To test for direct and indirect effects of a top predator on three lower trophic levels, we conducted two multiyear predator addition experiments in a tropical wet forest. Periodic additions of a top predator (predatory clerid beetle) to a wet forest understory shrub caused a reduction in the predatory beetle's prey (a predatory ant), increased herbivory, and reduced leaf area of the plant. The...
متن کاملImportance of species interactions to community heritability: a genetic basis to trophic-level interactions.
Recent community genetics studies have shown that specific genotypes of a host plant support distinct arthropod communities. Building upon these findings, we examined the hypothesis that a trophic community consisting of cottonwood trees, a galling herbivore and avian predators could also be related to the genetics of the host tree. We found genetic correlations among phytochemistry of individu...
