White-nose syndrome (WNS) has caused alarming declines of North American bat populations in the 5 years since its discovery. Affected bats appear to starve during hibernation, possibly because disruption normal cycles torpor and arousal. The importance hydration state evaporative water loss (EWL) for influencing duration bouts hibernating mammals recently led "the dehydration hypothesis," that cutaneous infection wing membranes with fungus Geomyces destructans causes which turn, increases...
Abstract Variation in prey resources influences the diet and behaviour of predators. When become limiting, predators may travel farther to find preferred food or adjust existing local resources. are habitat limited, resource abundance impacts foraging success. We analysed Myotis lucifugus (little brown bats) from Nova Scotia (eastern Canada) Northwest Territories (north‐western Canada). This distribution includes extremes season length temperature encompasses colonies on rural monoculture...
Abstract Characterizing variation in predator behaviour and, specifically, quantifying kill rates is fundamental for parameterizing predator–prey and food web models. Yet, current methods recording of free‐ranging predators, particularly those that consume small‐bodied (<2 kg) prey, present a number associated challenges. In this paper, we deployed custom‐adapted acoustic recorders tri‐axial accelerometers on Canada lynx Lynx canadensis to assess the capacity biologging devices...
Technological miniaturization is driving a biologging revolution that producing detailed and sophisticated techniques of assessing individual behavioral responses to environmental conditions. Among the many advancements this has brought an ability record nocturnal, free-ranging species. Here, we combine captive validations acceleration signatures with acoustic recordings from individuals classify behavior at two resolutions. Combining these classifications ~2 month-long recordings, describe...
Recovery targets fall short of culturally meaningful abundance.
Climate change disproportionately affects Indigenous Peoples because of strong connections between environmental, cultural, and spiritual well-being. While much the global discourse surrounding climate is founded in Western science, holistic, place-based knowledge offers a complementary way understanding mitigating impacts. The goal this research was to elevate Anishinaabe concerns, observations, perspectives about impacts future needs. We organized workshop called “Connecting Guardians...
Abstract The miniaturization and affordability of new technology is driving a biologging revolution in wildlife ecology with use animal‐borne data logging devices. Among many technologies, accelerometers are emerging as key tools for continuously recording animal behavior. Yet critical, but under‐acknowledged consideration the trade‐off between sampling rate duration, created by battery‐ (or memory‐) related constraints. This especially acute among small animals, causing most researchers to...
ABSTRACT Capture and handling of wildlife is often an important component studies where detailed demographic, behavioral, physiological, or health data are required. Yet, capturing sometimes controversial lacking public support because concern about effects on individuals. Investigating potential also to inform data‐censoring protocols when using information obtained from captured animals. We investigated the short‐term effect helicopter‐based capture movements free‐ranging bison ( Bison )...
Abstract Scavenging by vertebrates can have important impacts on food web stability and persistence, alter the distribution of nutrients throughout landscape. However, scavenging communities been understudied in most regions around globe, we lack understanding biotic drivers vertebrate dynamics. In this paper, examined how changes prey density carrion biomass caused population cycles a primary species, snowshoe hare Lepus americanus , influence northern boreal forest. We further impact...
Animal personality or temperament refers to individual differences in behaviour that are repeatable over time and across contexts. Personality has been linked life-history traits, energetic traits fitness, with implications for the evolution of behaviour. quantified a range taxa (e.g., fish, songbirds, small mammals) but, so far, there little work on bats, despite their diversity potential as model taxon comparative studies. We used novel environment test quantify brown bats (Myotis...
Abstract Parasitism is a consequence of complex interactions between host, parasite, and their shared environment, host behavior can influence parasite risk. Animal personality (i.e., consistent behavioral differences that are repeatable across time context) parasitism with more explorative individuals typically hosting greater loads. Host “sociality” known to impact risk social at higher acquiring or transmitting parasites, but other behaviors could also be important. We quantified in least...
Facing the global biodiversity crisis, conservation practitioners and decision-makers seek to catalyze wildlife recoveries in their region. Here we examined social-ecological attributes related threatened species recovery Canada. First, used a retrospective approach compare trajectories of original assessed by Canada’s species-at-risk committee found that only eight 36 now have decreased extinction risk relative past. There were no significant differences human or financial capacity provided...
Spatial confinement to a home range is theorized be more energetically efficient method of acquiring resources than random searching due spatial memory. Intraspecific studies that have compared size at different population densities found ranges shrink as density increases. This negative trend could increased conspecific competition via increase or correlations between resource and density. We use the 10-year cycle snowshoe hares (Lepus americanus) individual-level food-add experiments case...
Abstract Organisms survive environmental variation by combining homeostatic regulation of critical states with allostatic other traits, and species differences in these responses can contribute to coexistence temporally variable environments. In this paper, we simultaneously record three functional traits—body temperature ( T b ), heart rate activity—in relation forms variation—air a photoperiod experimentally manipulated resource levels—in free‐ranging snowshoe hares North American red...
Abstract Unbiased population density estimates are critical for ecological research and wildlife management but often difficult to obtain. Researchers use a variety of sampling statistical methods generate density, few studies have compared across methods. During 2016–2017, we surveyed Canada lynx ( Lynx canadensis ) in southwestern Yukon Territory, Canada, using track transect counts, hair snares, camera traps, live Global Positioning System (GPS) collars. From these data, estimated with...
Abstract Food availability and temporal variation in predation risk are both important determinants of the magnitude antipredator responses, but their effects have rarely been examined simultaneously, particularly wild prey. Here, we determine how food long‐term affect responses to acute by monitoring foraging response free‐ranging snowshoe hares ( Lepus americanus ) an encounter with a Canada lynx Lynx canadensis Yukon, Canada, over four winters (2015–2016 2018–2019). We this was influenced...
The assumption that activity and foraging are risky for prey underlies many predator–prey theories has led to the use of overlap as a proxy predation risk. However, simultaneous measures predator along with timing required test this have not been available. Here, we used accelerometry data on snowshoe hares ( Lepus americanus ) Canada lynx Lynx canadensis determine patterns predators match these precise predation. Surprisingly found kills were likely occur during day when inactive at night...
The strengths of Indigenous Knowledges and need for reconciliation are increasingly recognized within conservation, leading to a rise in collaborative, cross-cultural research initiatives. As both cultural keystone important harvest species, moose value non-Indigenous Peoples, presenting an opportunity pursue monitoring strategies that embrace the Western knowledges. While various frameworks provide theoretical direction on how do so, few resources outline apply them practice. Leaning...
