Elise Irwin, PhD

Biologist - Cooperative Fish and Wildlife Research Unit Headquarters

Research Interests

Elise currently leads the CRU communications team. Previously, Elise led a broad research program at Auburn University in fisheries ecology with emphasis on reduction of uncertainty regarding how anthropomorphic changes in riverine and other aquatic environments affect biological processes of aquatic species. Thematically her research has primarily investigated how management, landscape patterns and disturbance regimes affect biological processes in aquatic systems, with two main areas of focus: 1) effects of spatial and temporal arrangement of riverine habitat on population parameters of fishes and, 2) definition and reduction of uncertainty regarding functional relations between hydrologic and chemical characteristics of riverine environments and fish distribution, abundance and/or growth of fish and invertebrates.

Teaching Interests

Before leading the CRU communications team, Elise taught courses on river systems, structured decision making, and adaptive management at Auburn University and the U.S. Fish and Wildlife Service National Conservation Training Center in Sheperdstown, West Virginia.

Data from: Decision science for management of coastal ecosystems

Coastal management decisions are complex and include challenging tradeoffs. Decision science offers a useful framework to address such complex problems. We illustrate the process with several coastal restoration studies. Our capstone example is based on a recent barrier island restoration assessment project at Dauphin Island, Alabama, which included the development of geomorphological and ecologic

Pollinator conservation and climate science at the U.S. Geological Survey

Introduction Ecosystems—whether agricultural, urban, or natural—depend on pollinators, great and small. Pollinators in the form of bees, birds, butterflies, bats, and even moths provide vital, but often invisible services, from contributing to biodiverse terrestrial wildlife and plant communities to supporting healthy watersheds. Pollinator declines worldwide have been noted as land-use and climat

The loss of ecosystem services due to climate change and coastal development is projected to have significant impacts on local economies and conservation of natural resources. Consequently, there has been an increase in coastal management activities such as living shorelines, oyster reef restoration, marsh restoration, beach and dune nourishment, and revegetation projects.

A review of lethal thermal tolerance among freshwater mussels (Bivalvia: Unionida) within the North American faunal region

Freshwater mussels of the order Unionida are currently one of the most imperiled groups of organisms in the North American faunal region. Accurate risk assessments and development of effective management strategies for remaining populations require knowledge of thermal limits in the face of increasing surface water temperature due to climate change and various anthropogenic factors.

Toward improved prediction of streamflow effects on freshwater fishes

Understanding the effects of hydrology on fish populations is essential to managing for native fish conservation. However, despite decades of research illustrating streamflow influences on fish habitat, reproduction and survival, biologists remain challenged when tasked with predicting how fish populations will respond to changes in flow regimes. This uncertainty stems from insufficient understand
