Wildlife Biology, EarlyView.Wolf pup Canis lupus survival is a key driver of wolf population dynamics that remains poorly understood, especially in forested systems, because wolf pups are difficult to monitor. We used a combination of pup counts at dens and remote camera observations to estimate annual survival and recruitment of wolf pups in the Greater Voyageurs Ecosystem, MN ...

Wildlife Biology, EarlyView.In fenced protected areas where large carnivore populations persist or have been restored through reintroduction, population monitoring is essential to inform management. Robust density estimates are particularly important given the strong influence of large carnivores on ecosystem processes, yet such data remain scarce for arid systems where ...

Mark-recapture and mark-resight methods for estimating abundance with remote cameras: a carnivore case study. [PDF]
PLoS ONE, 2015 Abundance estimation of carnivore populations is difficult and has prompted the use of non-invasive detection methods, such as remotely-triggered cameras, to collect data.

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer
Wildlife Biology, EarlyView.Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Objective measurement of Akodon budini dorsal coloration: methodological concerns
Anais da Academia Brasileira de Ciências, 2016 The role of color in taxonomic and systematic studies of several taxa is central. Color data are more valuable if they permit comparisons. We aimed to provide pelage objective color measurements of a series of Akodon budini and to use those color data to

Fine‐scale spatial variation in eastern grey squirrel melanism across a complex urban landscape
Journal of Animal Ecology, EarlyView.By sampling 197 parks, the study demonstrates how natural geography creates divergence within cities. The findings reveal that the St. Lawrence River and its tributaries act as barriers, disrupting urban melanism clines in grey squirrels. Ultimately, the research indicates that natural features still dictate evolutionary rules in anthropogenic ...

Extensive population genetic structure in the giraffe
BMC Biology, 2007 Background A central question in the evolutionary diversification of large, widespread, mobile mammals is how substantial differentiation can arise, particularly in the absence of topographic or habitat barriers to dispersal. All extant giraffes (Giraffa

Integrative Zoology, EarlyView.The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
