Summary The probability of detecting the echolocation calls bats is affected by strength signal as well directionality and frequency response acoustic detectors. Regardless research question, it important to quantify variation in recording system performance its impacts on bat detection results. purpose this study was compare among five commonly used detectors: A na B at SD 2 ( T itley S cientific), visoft U ltra ound G ate 116 CM 16/ CMPA ioacoustics), atcorder 2·0 (ecoObs), atlogger E...
Molecular techniques are increasingly employed to recognize the presence of cryptic species, even among commonly observed taxa. Previous studies have demonstrated that bats using high-duty cycle echolocation may be more likely speciate quickly. Pteronotus parnellii is a widespread Neotropical bat and only New World species use echolocation, trait otherwise restricted Old Here we analyze morphological acoustic variation genetic divergence at mitochondrial COI gene, 7th intron region y-linked...
Summary Omnivory enables animals to fill more than one trophic niche, providing access a wider variety of food resources with potentially higher nutrient value, particularly when become scarce. Animals can achieve omnivory using different strategies, for example opportunistic foraging, or switching between multiple niches. The Neotropical bat Glossophaga soricina (Pallas, 1766) is common and widespread species known nectar feeding, but it also eats fruit insects. Approaching stationary...
Abstract Emerging infectious diseases in wildlife can threaten vulnerable host populations. Actions targeting habitat improvements to aid population resilience and recovery may be beneficial long‐term strategies, yet testing the efficacy of such strategies before major conservation investments are made challenging. The disease white‐nose syndrome (WNS) has caused severe declines several species North American hibernating bats. We tested a novel approach targeted at improving foraging...
As molecular tools for assessing trophic interactions become common, research is increasingly focused on the construction of interaction networks. Here, we demonstrate three key methods incorporating DNA data into network ecology and discuss analytical considerations using a model consisting plants, insects, bats their parasites from Costa Rica dry forest. The simplest method involves use Sanger sequencing to acquire long sequences validate or refine field identifications, example parasites,...
Abstract The world's rich diversity of bats supports healthy ecosystems and important ecosystem services. Maintaining biological systems requires prompt identification threats to biodiversity immediate action protect species, which for wide‐ranging bat species that span geopolitical boundaries warrants international coordination. Anthropogenic forces drive the throughout North America world. We conducted an expert elicitation assess status 153 in Canada, United States, Mexico. used...
Artificial light at night (ALAN) is a rapidly intensifying form of environmental degradation that can impact wildlife by altering light-mediated physiological processes control broad range behaviors. Although nocturnal animals are most vulnerable, ALAN's effects on North American bats have been surprisingly understudied. Most what known based decades-old observations around street lights with traditional lighting technologies increasingly replaced energy-efficient broad-spectrum lighting,...
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...
Abstract Echolocating bats face the challenge of actively sensing their environment through own emissions, while also hearing calls and echoes nearby conspecifics. How mitigate interference is a long-standing question that has both ecological technological implications, as biosonar systems continue to outperform man-made sonar in noisy, cluttered environments. We recently showed perched decreased calling rates groups, displaying behavioral strategy resembling back-off algorithms used...
Bacterial pathogens remain poorly characterized in bats, especially North America. We describe novel (and some cases panmictic) hemoplasmas (10.5% positivity) and bartonellae (25.5% across three colonies of Mexican free-tailed bats (
In southern Ontario, Canada, the range and distribution of bats is well known, but their activity in northeastern part province (north 47°N, east 85°W) poorly documented. Using acoustic sampling, we documented occurrence six species boreal forest Ontario: Eptesicus fuscus (Big Brown Bat), Lasiurus borealis (Eastern Red L. cinereus (Hoary Myotis lucifugus (Little M. septentrionalis (Northern Long-eared Lasionycteris noctivagans (Silver-haired Bat). Hoary Bats were recorded more frequently...
Context Identifying key spatio–temporal periods of an organism’s activity is important focus many ecological studies. Bat activity, as assessed by passive acoustic monitoring, can be extremely variable and currently there exists no agreed-upon method for identifying high activity. Aims We proposed a new application the space–time scan statistic (SaTScan) objective technique peak bat aimed to test validity SaTScan peaks in demonstrate its use assessing species-specific temporal patterns...
Artificial light at night (ALAN) is a global pollutant that disrupts circadian rhythmicity and broad range of physiological processes behaviors in animals. However, ALAN sensitivity can vary greatly even among closely related species urgently needs study for much the world's nocturnal wildlife, including bats. While an increasing number bat have recently been assessed tolerance, spatial extent ALAN's influence on bats has received little attention. This information need barrier to protection...
Bats are facing threats from disease, wind power development, and climate change, which causing populations of many species to decline. The northern range limits temperate not well characterized, but the true distribution threatened bat is critical information for their conservation. We used passive acoustic monitoring false-positive occupancy models estimate distributions six bats in Ontario (north ca. 50.5°N). confirmed presence big brown (Eptesicus fuscus), hoary (Lasiurus cinereus),...
Abstract Millions of bats are killed at wind energy facilities worldwide, yet the behavioural mechanisms underlying why vulnerable to turbines remain unclear. Anthropogenic stimuli that alter perceptions environment, known as sensory pollution, could create ecological traps and cause bat mortality farms. We review abilities evaluate potential associated with farms examine role spatial scale on perceptual pollutants facilities. Audition, vision, somatosensation olfaction modalities use...

Abstract Power line corridors are ubiquitous worldwide and commonly used by bats as habitat. Targeted management of these corridor habitats has the potential to aid bat populations, which is critically important given multifaceted threats facing species, including emerging infectious disease white‐nose syndrome (WNS) in North America. Here, we review known impacts existing power on three behaviours: foraging, roosting commuting. We also identify United States that would benefit from changes...
