Abstract Light pollution has been increasing around the globe and threatens to disturb natural rhythms of wildlife species. Artificial light impacts behaviour insectivorous bats in numerous ways, including foraging behaviour, which may turn lead altered prey selection. In a manipulative field experiment, we collected faecal samples from six species naturally dark artificially lit conditions, identified items using molecular methods investigate effects on Proportional differences were not...
This study examines mercury exposure in bats across the northeast U.S. from 2005 to 2009. We collected 1,481 fur and 681 blood samples 8 states analyzed them for total Hg. A subset (n = 20) are also methylmercury (MeHg). Ten species of represented this which two protected by Endangered Species Act (ESA 1973) other pending review. There four objectives paper: (1) examine correlates differences fur-Hg levels among all sampling sites, including age, sex, species, presence a Hg point source; (2)...
Little is known about the migration and movements of migratory tree-roosting bat species in North America, though anecdotal observations migrating bats over Atlantic Ocean have been reported since at least 1890s. Aerial surveys boat-based wildlife off Seaboard detected a possible diurnal event eastern red (Lasiurus borealis) September 2012. One was sighted approximately 44 km east Rehoboth Beach, Delaware during survey. Eleven additional were observed between 16.9 41.8 New Jersey, Delaware,...
Sharks have greater risk for bioaccumulation of marine toxins and mercury (Hg), because they are long-lived predators. Shark fins cartilage also contain β-N-methylamino-l-alanine (BMAA), a ubiquitous cyanobacterial toxin linked to neurodegenerative diseases. Today, significant number shark species found their way onto the International Union Conservation Nature (IUCN) Red List Threatened Species. Many large sharks threatened with extinction due in part growing high demand fin soup and,...
Different second-generation sequencing technologies may have taxon-specific biases when DNA metabarcoding prey in predator faeces. Our major objective was to examine differences recovery from bat guano across two different workflows using the same faecal extracts. We compared results between Ion Torrent PGM and Illumina MiSeq with similar library preparations analysis pipeline. focus on repeatability provide an R Notebook effort towards transparency for future methodological improvements....
Abstract Metabarcoding of prey DNA from fecal samples can be used to design behavioral experiments study the foraging behavior and sensory ecology predators. The frog-eating bat, Trachops cirrhosus, eavesdrops on mating calls its anuran prey. We captured wild T. cirrhosus identified remains in bats’ using metabarcoding two gene regions (CO1 16S). Bats were preying frogs previously unknown their diet, such as species genus Pristimantis, which occurred 29% samples. Twenty-three percent also...

Abstract In temperate forests, insectivorous bats need to use variable hunting strategies as prey availability fluctuates during the growing season. At sites with amounts of forested habitat, sympatric bat species may exhibit high dietary overlap, but mechanisms coexistence are unknown. We analyzed diets Myotis septentrionalis and sodalis in two different landscapes central Indiana, USA: a riparian agricultural site managed forest site, aiming assess interspecific overlap. collected fecal...
Economic prosperity and globalization are major drivers for development of international airports, but aviation-oriented businesses residential developments a by-product airport business models. Among the multitude planning considerations is habitat needs endangered wildlife species. Foraging data were analyzed from 57 bats during three time periods (1998–1999: pre-mitigation; 2005–2006: mitigation, 2014–2016: post-mitigation) long-term study Indiana ( Myotis sodalis) near Indianapolis...
