Context‐Dependent Effects of Beavers (Castor spp.) on Freshwater Pearl Mussels (Margaritifera margaritifera) in European Rivers 河狸对欧洲河流中的淡水珍珠贝 (Margaritifera margaritifera) 存在情境依赖性影响

Wildlife Letters, EarlyView.
The study explores how beavers (Castor spp.) affect endangered freshwater pearl mussels (Margaritifera margaritifera) in European rivers. Beaver dams can harm small, fragmented mussel populations by reducing flow, increasing sediment, and potentially limiting host fish movement, while larger populations may benefit from improved bed stability and ...

CANINE DISTEMPER VIRUS–ASSOCIATED ENCEPHALITIS IN FREE-LIVING LYNX (LYNX CANADENSIS) AND BOBCATS (LYNX RUFUS) OF EASTERN CANADA [PDF]

Journal of Wildlife Diseases, 2009
Between 1993 and 1999, encephalitis caused by morbillivirus was diagnosed by immunohistochemistry and histology in six lynx (Lynx canadensis) and one bobcat (Lynx rufus) in the eastern Canadian provinces of New Brunswick and Nova Scotia. Five of the six cases in lynx occurred within an 11-mo period in 1996-97.

Salvage logging after an insect outbreak reduces occupancy by snowshoe hares (Lepus americanus) and their primary predators

Global Ecology and Conservation, 2019
Salvage logging after a natural disturbance is controversial because it may disrupt forest succession and reduce the value of wildlife habitat, but few studies have examined consequences on predator-prey systems.

Heightened threats to small woodland caribou populations in Canada and key considerations for their persistence Menaces pesant sur les petites populations de caribou des bois au Canada et considérations essentielles à leur rétablissement

Wildlife Monographs, EarlyView.
Abstract Woodland caribou (Rangifer tarandus) are one of the most iconic wildlife species in Canada. These large ungulates depend on undisturbed, interconnected assemblages of mature and old‐growth conifer forests for survival, and exhibit life‐history traits typical of K‐selected species (i.e., low reproductive rates, long generation times, and slow ...

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Habitat Selection and Risk of Predation: Re-colonization by Lynx had Limited Impact on Habitat Selection by Roe Deer [PDF]

, 2013
Risk of predation is an evolutionary force that affects behaviors of virtually all animals. In this study, we examined how habitat selection by roe deer was affected by risk of predation by Eurasian lynx - the main predator of roe deer in Scandinavia ...

Stabilizing selection and mitochondrial heteroplasmy in the Canada lynx (Lynx canadensis)

Genome
Mitochondrial DNA is commonly used in population genetic studies to investigate spatial structure, intraspecific variation, and phylogenetic relationships. The control region is the most rapidly evolving and largest non-coding region, but its analysis can be complicated by heteroplasmic signals of genome duplication in many mammals, including felids ...

Transfer of radiocaesium (137Cs) to lynx (Lynx lynx) and brown bear (Ursus arctos) in Chernobyl affected areas in Sweden [PDF]

In this study, 137Cs activity concentration was measured in 266 lynxes hunted in early spring during the years 2006-2011 in central and northern Sweden and in 161 bears hunted in the end of August until October during the years 2010 and 2011.

Functional Responses Shape Node and Network Level Properties of a Simplified Boreal Food Web

Frontiers in Ecology and Evolution, 2022
Ecological communities are fundamentally connected through a network of trophic interactions that are often complex and difficult to model. Substantial variation exists in the nature and magnitude of these interactions across various predators and prey ...

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

Animal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...
