1. The size of an individual is important determinant its trophic position and the type interactions it engages in with other heterospecific conspecific individuals. Consequently individual's ecological role a community changes body over ontogeny, leading to that between individuals are size-dependent ontogenetically variable mixture competition predation. 2. Because differently sized thus experience different biotic environments, invasion success may be determined by invaders. Invasion...
Summary Size‐dependent interactions and habitat complexity have been identified as important factors affecting the persistence of intraguild predation ( IGP ) systems. Habitat has suggested to promote IG prey predator coexistence through weakening trophic particularly link. Here, we experimentally investigate effects on invasion success differently sized ‐predators in a size‐structured system consisting ‐predator P oecilia reticulata resident H eterandria formosa ‐prey population. The...
Abstract Patterns in biomass production are determined by resource input (productivity) and trophic transfer efficiency. At fixed input, variation consumer has been related to food quality, metabolic type diversity among species. In contrast, intraspecific individual body size because of ontogenetic development, which characterizes the overwhelming majority taxa, largely neglected. Here we show experimentally a long-term multigenerational study that reallocating constant two-stage system...
