Witryna25 lis 2008 · With 3 trophic levels (plants, herbivores, and carnivores), herbivores may be held in check by carnivores and thus inefficiently consume plant biomass. However, with 2 (or 4) levels, herbivore biomass is unconstrained (or less constrained) by predation, possibly leading to higher herbivore production relative to primary … Witryna13 gru 2024 · Herbivores and Trophic Levels .

WitrynaFirst, the relationship between diversity and the variability of trophic level biomass is independent of the degree of herbivore generalization (cf. figs. 1A, 1B and 2A, 2B) when herbivore voracity $$\hat{c}$$ does not depend on diversity, as in an article by Ives et al. .

Witryna23 kwi 2007 · In models with two trophic levels and covarying plant and herbivore diversity, Thébault & Loreau (2003, 2005) showed that the dependence of plant biomass on plant diversity can shift qualitatively from monotonically increasing to hump-shaped depending on the relationship between a plant's resistance to herbivory and its …

Witryna10 lut 2024 · Introduction. The concept of top-down control of communities gained traction with the introduction of the “green world hypothesis,” which proposed that plant abundance is regulated through predator-mediated control of herbivores (Hairston et al. 1960).This process of trophic cascading predicts that a perturbation at one trophic …
