Abstract The development and expansion of wind energy is considered a key global threat to bat populations. Bat carcasses are being found underneath turbines across North South America, Eurasia, Africa, the Austro‐Pacific. However, relatively little known about comparative impacts techniques designed modify turbine operations in ways that reduce fatalities associated with facilities. This study tests novel approach for reducing curtailment time at facility United States, then compares these...
Long Point, Ontario is an important stopover site for a variety of migrating birds and it may also serve bats. While bats often have been caught during mist netting at there no quantitative studies (or resident) this location. We monitored bat activity Point using mist-net captures recordings echolocation calls in June August 2006. Bat was significantly higher than June, suggesting peak coincident with when migration would be expected to occur. Lasionycteris noctivagans the only species...
A scarcity of baseline data is a significant barrier to understanding and mitigating potential impacts offshore development on birds bats. Difficult sometimes unpredictable conditions coupled with high expense make gathering such challenge. The Acoustic Thermographic Offshore Monitoring (ATOM) system combines thermal imaging acoustic ultrasound sensors continuously monitor bird bat abundance, flight height, direction, speed. ATOM's capabilities are discussed, illustrated using onshore test...
Passive acoustic monitoring is a common tool used for bat activity levels. Identifying periods and locations of peak levels provides insight into ecology has important management implications. One limitation passive the relative nature data, often relying on subjective interpretation descriptive terminology such as “higher” or “lower”. We propose use percentile thresholds (PTs) objectively identifying activity. By compiling reference data set, it possible to define percentiles observed these...
We studied spatial variation in echolocation call structure of the little brown bat (Myotis lucifugus (LeConte, 1831)) by analysing calls recorded from free-flying individuals at 1 site Haida Gwaii, British Columbia, Chautaqua, New York, and 20 sites along Hudson River, York. controlled for factors that are often thought to lead interspecific (habitat, ontogeny, presence conspecifics, recording techniques, ambient conditions), which allowed us focus on effect scale structure. As predicted,...
Emerging infectious diseases can have substantial impacts on wildlife health, but also provide an opportunity to understand how populations respond novel selective pressures. White-nose syndrome (WNS) has decimated some of bats in eastern North America, vary among species. We counted 11 hibernacula Ontario, Canada, before and after WNS arrived, compared the relative abundance 5 bat species captured pre-WNS (1966–1968 2007–2009) post-WNS (2017–2019) during swarming at one these hibernacula....
Sediments of the upper Hudson River, New York, USA, contain polychlorinated biphenyls (PCBs). Consequently, elevated levels PCBs have been found in tissues bats and their insect prey along this region. However, it is not clear whether bat activity foraging behaviour affected. To assess possible effects on behaviour, we measured little brown (Myotis lucifugus (LeConte, 1831)) hoary (Lasiurus cinereus (Palisot de Beauvois, 1796)) as well abundance at same locations. We also duration distances...
