Spatial and seasonal relationships between Pacific harbor seals (Phoca vitulina richardii) and their prey, at multiple scales [PDF]

, 2009
Knowing where pinnipeds forage is vital to managing and protecting their populations, and for assessing potential interactions with fisheries. We assessed the spatial relationship between the seasonal distribution of Pacific harbor seals (Phoca vitulina

THE ART OF WAR: PATTERNS AND MECHANISMS UNDERLYING PREDATOR-INDUCED PLASTICITY OF AMPHIBIANS [PDF]

, 2013
Organisms often employ phenotypic plasticity as a strategy to cope with variable environments. This is particularly true of predation threats, wherein prey induce defenses to reduce detection or capture by predators.

A two-strain ecoepidemic competition model

, 2014
In this paper we consider a competition system in which two diseases spread by contact. We characterize the system behavior, establishing that only some configurations are possible.

Cameras or Camus? Comparing Snow Track Surveys and Camera Traps to Estimate Densities of Unmarked Wildlife Populations

Ecology and Evolution
Population density is a valuable metric used to manage wildlife populations. In the Russian Far East, managers use the Formozov‐ Malyushev‐Pereleshin (FMP) snow tracking method to estimate densities of ungulates for hunting management.

Rice fields as alternative foraging grounds: Rising shorebird diversity and abundance despite declines in natural coastal wintering sites

Ecological Indicators
This study investigates the extent to which shorebirds confront habitat degradation at the natural wetlands (mudflats, mangroves, sand beaches) by shifting to adjacent rice fields for foraging. Our results showed an overall decline in shorebird abundance
