L’inventaire acoustique constitue la meilleure méthode pour déterminer la présence des différentes espèces de chauves-souris à un site donné. En effet, puisque les chauves-souris émettent des cris d’écholocation lors de leurs déplacements et pour se nourrir, l’utilisation d’enregistreurs d’ultrasons améliore la probabilité de détecter les chauves-s...

Le Québec constitue la limite nord de la répartition des huit espèces de couleuvres retrouvées sur le territoire. Toutes ces espèces, hormis la couleuvre rayée et la couleuvre à ventre rouge, figurent sur la Liste des espèces susceptibles d’être désignées menacées ou vulnérables du gouvernement du Québec. Les couleuvres sont généralement discrètes...

Ce rapport présente une évaluation de la translocation en tant que mesure de mitigation pour la couleuvre brune au Québec. Si une translocation à courte distance dans un contexte d’une perturbation temporaire ou de destruction partielle apparait justifiée sans présenter d’enjeux d’efficacité, de risques associés à la propagation de maladies ou à la...

Genetic diversity within and among populations is frequently used in prioritization processes to rank populations based on their vulnerability or distinctiveness, however, connectivity and gene flow are rarely considered within these frameworks. Using a wood turtle (Glyptemys insculpta) population graph, we introduce BRIDES as a new tool to evaluat...

The wood turtle (Glyptemys insculpta) is a freshwater species endemic to eastern North America and is currently listed as endangered by the International Union for Conservation of Nature. Wood turtle local populations are considered units for the species recovery, and are defined as discrete interbreeding populations in a distinct watershed; howeve...

Boreal Chorus Frogs (Pseudacris maculata) are widely distributed across North America; however, populations in parts of southeastern Canada and northeastern United States have been designated as either vulnerable or threatened because of human land use, and pressures from housing developments continue to jeopardize remnant populations found within...

Most bat species in Québec are at risk owing, among other things, to the human-induced threats facing bat populations. Wind energy development is one of those threats. This document presents a review of the literature, with several objectives. First of all, we document the extent and impacts of bat collisions in wind farms in North America and Québ...

Mating system characteristics are of great importance as they may influence male and female reproductive success and reproductive isolation. The wood turtle (Glyptemys insculpta) is a terrestrial freshwater species listed as endangered by the International Union for Conservation of Nature. Considering its conservation status and the paucity of info...

La plupart des espèces de chauves-souris du Québec sont dans une situation précaire en raison, entre autres, des menaces anthropiques qui pèsent sur les populations. Le développement éolien compte au nombre de ces menaces. Le présent document est une revue de littérature qui vise plusieurs objectifs. D’abord, on documente les impacts et l’ampleur d...

The two species of flying squirrels found in North America are the northern (Glaucomys sabrinus) and the southern (G. volans) flying squirrel. Both species have wide range distributions across North America, yet differences in their preferred habitat result in few areas of sympatry. Climate change however, has shifted the southern flying squirrel’s...

New records of the Southern Flying Squirrel (Glaucomys volans) in Quebec expand its known range in the province 150 km east to the appalachian foothills and farther west than previously assumed. We obtained individuals through live trapping, trapper collaboration, and opportunistic discoveries. Species identification was confirmed with morphologica...

Modification of a species range is one of many consequences of climate change and is driving the emergence of Lyme disease in eastern Canada. The primary reservoir host of the bacteria responsible for Lyme disease, Borrelia burgdorferi, is the white-footed mouse (Peromyscus leucopus), whose range is rapidly shifting north into southern Québec. The...

Lyme borreliosis is rapidly emerging in Canada, and climate change is likely a key driver of the northern spread of the disease in North America. We used field and modeling approaches to predict the risk of occurrence of Borrelia burgdorferi, the bacteria causing Lyme disease in North America. We combined climatic and landscape variables to model t...

This paper presents the results of a long-term study to detect the presence of Puma concolor (Cougar) in eastern Canada. We installed 38 scratching posts to attract wild Cougars and collect hair samples in several national and provincial parks in Quebec, New Brunswick, and Nova Scotia. A set of semi-nested primers was used to discriminate Cougar sa...

The white-footed mouse (Peromyscus leucopus) has expanded its northern limit into southern Qu ebec over the last few decades. P. leucopus is a great disperser and colonizer and is of particular interest because it is considered a primary reservoir for the spirochete bacterium that causes Lyme disease. There is no current information on the gene flo...

Genetic markers play an important role in elucidating taxonomic uncertainties for a wide range of organisms. We present a set of specific primers to distinguish between Canis mitochondrial DNA (mtDNA) of New World (North American) and Old World (Eurasian) origin using the ATP-8 region and gel electrophoresis. We amplified mtDNA from Old World (gray...

Contemporary evolution through human-induced hybridization occurs throughout the taxonomic range. Formerly allopatric species appear especially susceptible to hybridization. Consequently, hybridization is expected to be more common in regions with recent sympatry owing to human activity than in areas of historical range overlap. Coyotes (Canis latr...

Morphometric measurements or biochemical methods are often required to differentiate deer mice, Peromyscus maniculatus (Wagner, 1845), from white-footed mice, Peromyscus leucopus (Rafinesque, 1818), particularly when they are found in sympatry. However, these approaches cannot easily be applied to juveniles, or to degraded or ancient museum specime...

Throughout its range, the long-term persistence of the wood turtle (Glyptemys insculpta Le Conte, 1830) is jeopardized by habitat perturbations and commercial collection. The main objective of this study was to acquire knowledge on the genetic structure of wood turtle populations within Quebec, where the species reaches the northernmost limit of it...

La tortue des bois (Glyptemys insculpta) est une espèce menacée au Canada. Au Québec, la majorité des populations sont menacées ou en voie de disparition. Les plus grandes menaces pour cette espèce sont liées à la perte et à la fragmentation des habitats, aux mortalités routières, à la prédation excessive, à la machinerie agricole ainsi qu’aux acti...

Estimation of effective population sizes (N(e)) and temporal gene flow (N(e)m, m) has many implications for understanding population structure in evolutionary and conservation biology. However, comparative studies that gauge the relative performance of N(e), N(e)m or m methods are few. Using temporal genetic data from two salmonid fish population s...

The myiasis-causing flies Cuterebra grisea (Coquillet) and Cuterebra fontinella (Clark) (Diptera: Oestridae) are normally parasites of mice, predominantly of the genus Peromyscus. The morphological similarities of these species and the existence of intermediate morphotypes bearing characters of both species make the identification of adults problem...

We assessed the genetic relationships among landlocked populations and parapatric anadromous populations of Atlantic salmon (Salmo salar) from the Saguenay River system to infer the alternative scenarios of single versus double origin of salmon in Lake Saint-Jean, Quebec, Canada. We predicted that the hypothesis of double origin would be supported...

It may often be necessary to perform genetic analyses of temporal replicates to estimate the significance of spatial variation independently from that of temporal variation in order to ensure the reliability of estimates of a defined population structure. Nevertheless, temporal studies of genetic diversity remain scarce in the literature relative t...

Four tributaries of Lake St-Jean (Québec, Canada) are used for spawning and juvenile habitat by land-locked Atlantic salmon. Spawning runs have drastically declined since the mid-1980s, and consequently, a supportive-breeding programme was undertaken in 1990. In this study, we analysed seven microsatellite loci and mtDNA, and empirically estimated...

This study investigates the patterns of genetic diversity detected in allozymes, mtDNA, and microsatellites, in order to assess their relative efficacy to differentiate sympatric landlocked salmon populations and to estimate changes in genetic diversity between wild and first-generation hatchery fish. Overall, the three genetic markers indicated a...
