Coexistence Shapes Antipredator Defenses
8 Invasive alien predators can impose strong selection on native prey populations and induce rapid 9 evolutionary change in the invaded communities. However, studies on evolutionary responses to 10 invasive predators are often complicated by the lack of replicate populations differing in 11 coexistence time with the predator, which would allow determining how prey traits change during 12 the in...
متن کاملEcological drivers of antipredator defenses in carnivores.
Mammals have evolved several morphological and behavioral adaptations to reduce the risk of predation, but we know little about the ecological factors that favor their evolution. For example, some mammalian carnivores have the ability to spray noxious anal secretions in defense, whereas other species lack such weaponry but may instead rely on collective vigilance characteristic of cohesive soci...
متن کاملAntipredator behavior promotes diversification of feeding strategies.
Animals often facultatively engage in less risky behavior when predators are present. Few studies, however, have investigated whether, or how, such predator-mediated behavior promotes diversification. Here, we ask whether tadpoles of the spadefoot toad Scaphiopus couchii have a diminished ability to utilize a potentially valuable resource--anostracan fairy shrimp--because of behavioral response...

متن کاملMutuality, Diversification and Deposit Rates
There is an increased sophistication in the provision of financial services by UK financial mutuals. This paper presents evidence of a more complex process of price setting by these firms. From a theoretical model of the determination of deposit rates, the rate setting behaviour of firms is estimated empirically. Controlling for different service provision and firm characteristics heterogeneous...
