Predation Under Perfect Information [PDF]

In an oligopoly configuration characterized by high barriers to (re-)entry, a finite horizon, perfect information about demand and costs and the presence of three identical firms, we show that two of them (the predators) can choose to charge an initial ...

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Habitat heterogeneity overrides local processes to drive the species–area relationship of benthic macroinvertebrates in shallow floodplain lakes

Ecography, EarlyView.
The species–area relationship (SAR) on islands describes how the numbers of species increase with increasing island size (or island‐like habitat, such as lakes). Despite its conceptual importance, there is considerable uncertainty surrounding its shape in freshwater lakes, as well as the potential mechanisms that underlie the SAR.

Dynamic riskscapes for prey: disentangling the impact of human and cougar presence on deer behavior using GPS smartphone locations

Ecography, EarlyView.
Prey species adjust their behavior along human‐use gradients by balancing risks from predators and humans. During hunting seasons, prey often exhibit strong antipredator responses to humans but may develop tolerance in suburban areas to exploit human‐mediated resources.

Living in the edge: demographic responses driven by density‐dependence and pulsed resources in a hibernating mammal

Ecography, EarlyView.
Populations at the edge of a species' distribution often encounter more challenging environmental conditions than those at the core, requiring unique adaptations and strategies. However, the demographic processes driving these populations remain poorly understood.

Assessing benthos through predator stomach contents: spatiotemporal modeling of abundance and habitat use

Ecography, EarlyView.
In shelf ecosystems, benthic invertebrates facilitate nutrient recycling and the transfer of energy to higher trophic levels. However, large‐scale monitoring through direct sampling (e.g. using benthic grabs or bottom trawls) can be costly in terms of time and labor.
