Abstract Motion‐sensitive cameras are commonly used to monitor wildlife occupancy rates; however, few studies have assessed whether data from correlated with density estimates obtained more traditional labor‐intensive methods such as those based on capture‐mark‐recapture. We a boreal forest community test camera were densities estimated independent monitoring methods. placed 72 covert in the around Lhù'ààn Mân' (Kluane Lake), Yukon, Canada, for 7 years and tracked changes population by hit...
ABSTRACT The potential for interspecific competition food resources is a key consideration when newly introduced ungulates occupy shared range with resident native species. Management plans in Yukon, Canada, reintroduced bison ( Bison ) and elk Cervus canadensis called an assessment of between these species populations caribou Rangifer tarandus ), thinhorn sheep Ovis dalli moose Alces americanus ). To assess among ungulates, we examined dietary overlap 7 ungulate southwestern Canada. We...
The Beringian Coevolution Project (BCP), a field program underway in the high northern latitudes since 1999, has focused on building key scientific infrastructure for integrated specimen-based studies mammals and their associated parasites. BCP contributed new insights across temporal spatial scales into how ancient climate environmental change have shaped faunas, emphasizing processes of assembly, persistence, diversification vast region. collections also represent baseline records biotic...
Understanding parasite diversity and distribution is essential in managing the potential impact of parasitic diseases animals people. Imperfect diagnostic methods, however, may conceal cryptic species. Here, we report discovery phylogeography a previously unrecognized species Trichinella wolverine (Gulo gulo) from northwestern Canada that was indistinguishable T. nativa using standard multiplex PCR assay based on expansion segment 5 (ESV) ribosomal DNA. The novel genotype, designated as T13,...
Recent studies have suggested that old-growth forests may be important habitat for some species of bats, but the proximate factors related to greater bat activity in older are not well understood. To assess relative use by we used ultrasonic detectors and mist nets sample activities among white pine (Pinus strobus) mixed woods, mature boreal-type selectively logged woods central Ontario. We Quantified 15 structural characteristics 21 stands sampled activity. Detection rates Myotis species,...
Abstract Estimating population densities of small mammals (< 100g) has typically been carried out by intensive livetrapping, but this technique may be stressful to animals and the effort required is considerable. Here, we used camera traps detect mammal presence assessed if provided a feasible alternative livetrapping for density estimation. During 2010–2012, trapping in conjunction with mark–recapture estimate northern red-backed voles ( Myodes rutilus ) deer mice Peromyscus...
Wolverines are vulnerable to multiple, widespread, increasing forms of human activity so have become an indicator conservation success or failure for northern ecosystems. Logistically difficult research, the last two decades seen marked changes in technology yielding new insights. We reviewed and synthesized this recent research asked: what known drivers wolverine populations distribution, is there consensus on mechanisms dynamics, how can knowledge inform conservation? From 156...
The boreal forest, the world’s largest terrestrial biome, is undergoing dramatic changes owing to anthropogenic stressors, including those of climate change. To track ecosystem through space and time, robust monitoring programs are needed that survey a variety constituents. We monitored white spruce ( Picea glauca ) cone crops, berry Empetrum nigrum, Shepherdia canadensis production, above-ground mushroom abundance, abundance small mammals Clethrionomys rutilus , Peromyscus maniculatus ),...
From 1988-1992 wood bison (Bison athabascae) were transplanted to the southwest Yukon, inadvertently creating concerns among local First Nations about their impacts on other wildlife, habitat, and members' traditional livelihoods. To understand these we conducted a participatory impact assessment based multistage analysis of existing new qualitative data. We found had since become valued food resource, though there was socially-determined carrying capacity for this population. Study...
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 Reduced food availability is implicated in declines avian aerial insectivores, but the effect of nutritional stress on mammalian insectivores unclear. Unlike birds, insectivorous bats provision their young through lactation, which might protect nursing juveniles when prey low could increase energetic burden lactating females. We analyzed a 15‐year capture–mark–recapture data set from 5312 individual little brown myotis ( Myotis lucifugus ) captured at 11 maternity colonies...
Abstract Globally, ungulate–vehicle collisions (UVCs) are a major human safety concern and may also represent significant source of mortality for some ungulate populations. However, records UVC based on counts roadside carcasses or reports by drivers involved in these incidents assuredly underestimated because not all ungulates struck die immediately at the reported authorities. Here, we provide an observation analysis movements GPS‐collared bison ( Bison ) that was Alaska Highway died thick...
Abstract The Wolverine (Gulo gulo) is a cold-adapted species of conservation interest because it sensitive to human development, disturbance, exploitation, and climate warming. populations have been studied across much their distributional range evaluate patterns genetic diversity, structure, gene flow. Little population structure has detected in northwestern North America with microsatellite loci, but low genomic diversity wolverines may limit detection differences this highly vagile...
Abstract The frequency and severity of extreme weather events such as heat waves are increasing globally, revealing ecological responses that provide valuable insights toward the conservation species in a changing climate. In this study, we utilized data from two populations GPS‐collared female wood bison ( Bison athabascae ) boreal forest northwestern Canada to investigate their movement behaviors response 2021 Western North American Heat Wave. Using generalized additive mixed‐effect models...
Recently, a new generation of global positioning system (GPS) collars has become available that provides limited daily location fixes, relatively long battery life, and are low‐cost, compared to full‐featured GPS collars. However, their performance is untested, assessing these biases needed inform study designs data analysis protocols. We used stationary tests 15 Lotek LifeCycle – an example low‐feature measure the accuracy fixes. In addition, we deployed Lifecycle on 153 caribou Rangifer...
Diurnal roost sites are a critical resource for bats. Despite their importance, we know little about the roosting habits of Little Brown Myotis (Myotis lucifugus) in boreal forest northwestern Canada and Alaska. To locate diurnal determine minimum distances to foraging areas, radio-tagged 10 (7 adult females, 3 males) southwestern Yukon, Canada. All females roosted single building, with 1 using bat house 2 nights. In contrast, males used variety sites, including buildings, rock cliffs,...
Abstract Urban development is detrimental to many wildlife species; however, endangered little brown bats ( Myotis lucifugus ) may be attracted human settlements, making them a synurbic species. Buildings likely provide high‐quality roosting habitat, which limiting factor in the boreal forest where trees are typically small and potentially unsuitable for hosting large maternity colonies. In forest, there relatively few urban developments matrix of wilderness apparently suboptimal natural...
Public support is often instrumental for restoring large mammals to landscapes where they have been extirpated. Effective conservation planning likely hinges on wildlife managers understanding and reflecting the values beliefs of their constituencies. Yet, comparative views public or key interest groups are largely untested. As a prelude developing management plan reintroduced bison (Bison bison) in Yukon, Canada, we compared public, hunters, managers, using pre-tested questionnaire with...
Rabies continues to affect wildlife and domestic animals in northern Canada Alaska, but no cases have been reported the Yukon since 1970s. To better understand presence of rabies territory, a surveillance program began 2009, using opportunistically collected samples from 13 species wild mammals. Samples were trapped through carcass collection programs, that found dead by public, those involved human-wildlife conflict or vehicle collisions. All (n=763) negative for virus antigen. Five (<1%...
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...
