Abstract:
... A major component of sex‐allocation theory, the Trivers–Willard model (TWM), posits that sons and daughters are differentially affected by variation in the rearing environment. In many species, the amount of parental care received is expected to have differing effects on the fitness of males and females. When this occurs, the TWM predicts that selection should favour adjustment of the offspring se ...

Subject:
parasites; parasitism; animal ecology; invertebrates; predators; Baetis; Asellus aquaticus; predation; fish; invasive species; Gammarus pulex; Simulium; predator-prey relationships; prediction
Abstract:
... Predatory functional responses play integral roles in predator–prey dynamics, and their assessment promises greater understanding and prediction of the predatory impacts of invasive species. Other interspecific interactions, however, such as parasitism and higher‐order predation, have the potential to modify predator–prey interactions and thus the predictive capability of the comparative functiona ...
