Quantifying uncertainty when extrapolating the relationship between snorkel counts and mark-recapture estimates of juvenile salmonids
Matthew Richard Falcy, Ronald J. Constable Jr.
2024, Canadian Journal of Fisheries and Aquatic Sciences (81) 1279-1291
Snorkel surveys are frequently used to monitor stream-dwelling fish. Inferring local abundance from snorkel surveys is complicated by two primary factors: variable fish detection probabilities and the relative abundance of fish in habitat types below the recommended minimum depth for snorkeling. We examine these factors across three salmonid species (Oncorhynchus spp.),...

Devin Johnson, Joseph Michael Eisaguirre, Rebecca L. Taylor, Erik Andersen, Joel Garlich-Miller
2024, Preprint
Harvest sustainability is a primary goal of wildlife management and conservation, and in a changing world it is increasingly important to consider environmental drivers of population dynamics alongside harvest in cohesive management plans. This is particularly pertinent for harvested species that are acutely experiencing effects of climate change. The Pacific...

2024, Book chapter, Amphibian conservation action plan: A status review and roadmap for global amphibian conservation
Amphibian ecology and distribution are strongly correlated with climate. Regional patterns of amphibian biodiversity are intimately linked to temperature, evapotranspiration rate, and clines in humidity. While amphibians are and will continue to be adversely affected by recent and projected changes in climate, research suggests that adaptation may happen more slowly...

2024, Technical Report ERDC-TR-24-12
The curve number method first developed by the US Department of Agriculture Soil Conservation Service (now the Natural Resources Conservation Service) is often used for post-wildfire runoff assessments. These assessments are critical for land and emergency managers making decisions on life and property risks following a wildfire event. Three approaches...
North American bird banding program longevity records
Lauren Emily Walker, Matthew Rogosky, Kyra Harvey
2024, Newsletter
Longevity in wild birds refers to the longest-lived individual of any particular species. This measure of age can reflect important life history traits and identifying differences in longevity patterns between species can reveal unique threats or conservation needs. Because it requires the identification of individual birds, longevity can...

Advancing the understanding of Cyano-HABs in New York State
Tony Prestgiacomo, Jennifer L. Graham, Guy M. Foster
2024, Report
Most harmful algal blooms (HABs) in freshwater lakes, rivers, and streams are caused by cyanobacteria (Cyano-HABs). Under certain environmental conditions, dense concentrations (blooms) can form, which have the potential to cause aesthetic, ecological, and economic damage to afflicted waterbodies. Most importantly, Cyano-HABs can cause physical harm to people, pets, and...
