Ultrasonic Measurement of Body Fat as a Means of Assessing Body Condition in Free-Ranging Raccoons (Procyon lotor)

International Journal of Zoology, 2010
Assessment of body condition of free-ranging animals is important when evaluating population health and fitness. The following study used body condition scoring, ultrasound, and dissected physical measurement to assess fat stores in free-ranging raccoons

Characterizing Nontarget Species Use at Bait Sites for White-Tailed Deer

Human-Wildlife Interactions, 2017
Baiting white-tailed deer (Odocoileus virginianus) has evolved into a controversial issue of wildlife management. During August–September 2012, we established a grid of 64 cameras in the Upper Peninsula of Michigan at sites baited with corn that ...

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, EarlyView.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

Wildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained

Wild pigs (Sus scrofa) prefer inoculated peanuts over whole‐kernel corn in cafeteria‐style study

Wildlife Society Bulletin, EarlyView.
In this study, we explored bait preference of wild pigs (Sus scrofa), a highly invasive species where primary removal efforts include the use of bait and corral‐style trapping. In addition, we investigated preferences of a common nontarget to identify a bait that is preferred by wild pigs and not by white‐tailed deer (Odocoileus virginianus).

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

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 ...

Sustainable Protection of the Lesser Spotted Eagle in Germany by Purchasing Land and Managing the Reproduction Rate

Пернатые хищники и их охрана, 2018
The Lesser Spotted Eagle (Clanga [Aquila] pomarina) is the most endangered German eagle species, and is close to extirpation in the country. Various factors are responsible for the decline of the population, and the shrinking of its distribution to a ...

Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals

Integrative Zoology, EarlyView.
We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying
