A Unified Research Strategy for Disease Management

As wildlife diseases increase globally, an understanding of host-pathogen relationships can elucidate avenues for management and improve conservation efficacy. Amphibians are among the most threatened groups of wildlife, and disease is a major factor in global amphibian declines.

Large-scale Review of Amphibian Species and Community Response to Climate Change

Amphibian species and community richness has been declining in North America and climate change may play a role in these declines. Global climate change has led to a range shift of many wildlife species and thus understanding how these changes in species distribution can be used to predict amphibian community responses that may improve conservation efforts.

The influence of seep habitats on sediment macrofaunal biodiversity and functional traits

Chemosynthetic ecosystems in the Gulf of Mexico (GOM) support dense communities of seep megafaunal invertebrates that rely on endosymbiotic bacteria for nutrition. Distinct infaunal communities are associated with the biogenic habitats created by seep biota, where habitat heterogeneity and sediment geochemistry ...

Expectations of Maurepas Swamp response to a river reintroduction, Louisiana

Mississippi River reintroductions (freshwater diversions) into wetlands previously disconnected from the river have been implemented in southeastern Louisiana as a means to rehabilitate degraded and submerging wetlands. To date, all active Mississippi River reintroductions have targeted marsh habitat. However, a 57 cubic meter per second (2,000...

Stable isotope analysis enhances our understanding of diamondback terrapin Malaclemys terrapin foraging ecology

Dietary studies on generalist predators may provide valuable information on spatial or temporal changes in the structure of ecological communities. We initiated this study to provide baseline data and determine the utility of stable isotope analysis (SIA) to evaluate the foraging strategies of an opportunistic reptilian predator, the diamondback...
