The Impact Of Covid-19 On Wildlife Strike Rates In The United States, Dan Parsons, Michael Malouf, Wayne Martin Jan 2022

The Impact Of Covid-19 On Wildlife Strike Rates In The United States, Dan Parsons, Michael Malouf, Wayne Martin

Human–Wildlife Interactions

Shortly after the COVID-19 pandemic impacted air traffic, industry bodies warned of the potential increase in wildlife strike risk. Prior to the pandemic, wildlife strikes were already a concern to the industry. We sought to evaluate industry warnings using interrupted time series analysis of wildlife strike trends in the United States. Using pre-pandemic wildlife strike trends, we compared a forecast of the expected monthly strike rates through the COVID-19 impact period (March 2020 to December 2020) to the actual wildlife strike rates for the same period. Our results showed an increase in wildlife strike rates in 5 out of the …


Geographic And Seasonal Variation Of Flying Squirrel Vocalizations In California, Travis A. Farwell Jan 2022

Geographic And Seasonal Variation Of Flying Squirrel Vocalizations In California, Travis A. Farwell

Cal Poly Humboldt theses and projects

Advancements in bioacoustics field studies have further elucidated spatial, temporal, and behavioral aspects of otherwise-cryptic species, as well as offering insights into species communication. The discovery of high-frequency vocalizations in North American flying squirrels in particular has allowed researchers to use ultrasonic acoustic recorders to detect these cryptic species in the wild. Investigations into vocalizations of northern flying squirrels (Glaucomys sabrinus) and southern flying squirrels (G. volans) have highlighted call type variation between species and the potential use of recorders as a tool to examine vocal activity patterns. However, high-frequency vocalizations had yet to be quantitatively …
