Predation is a pervasive force that structures food webs and directly influences ecosystem
functioning. The relative body sizes of predators and prey may be an important determinant …

Antipredator responses are a key determinant of the successful persistence of prey, and
behavioural modifications are a frequent antipredator strategy. However, conspecific …

Considerable theoretical work predicts that intraspecific trait variation can have profound
ecological consequences by altering species interactions. Because of their high flexibility …

Rapid adaptation of defenses can alter ecological dynamics following introduction of a new
predator. We tested for local adaptation in Wood Frog (Rana sylvatica) populations that face …

Animals must balance the conflicting needs to forage and avoid predation. The optimal
balance of risk and reward should depend on the individual's state, particularly hunger …

The development of diverse capture mechanisms during foraging allows predators to select
their preys and succeed in their capture, with the least energy expenditure possible. In this …

Intraspecific phenotypic variation is a significant component of biodiversity. Body size, for
example, is variable and critical for structuring communities. We need to understand how …

Ecological relationships and processes vary across species' geographic distributions, life
stages and spatial, and temporal scales. Montane landscapes are characterized by low …

Behavioural consistency (ie personality) is an important aspect of behavioural ecology that
has yet to be thoroughly examined in amphibians. Currently published studies often address …

The effects of many pesticides on aquatic ecosystems remain poorly understood, especially
in naturalistic communities in which organisms are connected by a complex array of direct …
