Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

Wildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained

Examining inter‐regional and intra‐seasonal differences in wintering waterfowl landscape associations among Pacific and Atlantic flyways

Journal of Avian Biology
The Central Valley of California (CVC) and Mid‐Atlantic (MA) in the U.S. are both critical sites for nationwide food security, and many waterfowl species annually, especially during the winter, providing feeding and roosting locations for a variety of ...

Modeling Waterfowl Damage to Crops Surrounding the Quill lakes in Saskatchewan

Human-Wildlife Interactions, 2017
Waterfowl using the Central Flyway congregate on staging lakes before fall migration. The Quill lakes area of Saskatchewan Province, Canada, contains many staging lakes, which are surrounded by annual cropland.

Wildlife management in the United States – thoughts on evolving to better address species overabundance and disease transmission

Wildlife Society Bulletin, EarlyView.
Management options and actions are important for responsibly working to keep populations of sometimes overabundant species of invasive and native wildlife at levels that keep damage (e.g., agricultural, environmental, human health and safety) and disease (e.g., species specific, shared with livestock, zoonotic) associated with them at acceptable levels.

Decision‐centered systems for the future of wildlife conservation

Wildlife Society Bulletin, EarlyView.
This paper defines decision‐centered systems that align institutions, organizations, and science around explicit wildlife conservation decisions, so knowledge needs are decision‐driven, evidence informs analysis, and success is judged by conservation outcomes.

Prevalence and genetic diversity of haematozoa in South American waterfowl and evidence for intercontinental redistribution of parasites by migratory birds

International Journal for Parasitology: Parasites and Wildlife, 2015
To understand the role of migratory birds in the movement and transmission of haematozoa within and between continental regions, we examined 804 blood samples collected from eleven endemic species of South American waterfowl in Peru and Argentina for ...

When variability is not failure: Rethinking wildlife management in nonstationary systems

Wildlife Society Bulletin, EarlyView.
Departures from historical baselines do not always signal population decline. Under directional environmental change, variability in reproduction, migration, and distribution may instead reflect adaptive responses. Effective conservation requires managers to reinterpret variability, incorporate cognitively and institutionally diverse perspectives, and ...

Are migratory waterfowl vectors of seagrass pathogens?

Ecology and Evolution, 2020
Migratory waterfowl vector plant seeds and other tissues, but little attention has focused on the potential of avian vectoring of plant pathogens.
