Understanding the potential effect apex predators may have on riparian plant communities, via a trophic cascade, represents an important research challenge in Rocky Mountain ecosystems. In the northern ungulate winter range of Yellowstone National Park where grey wolves (Canis lupus) were historically present, absent for seven decades, and recently reintroduced, our objective was to evaluate pa...

We re-evaluated findings from Lenarz et al. (2009) that adult moose (Alces alces) survival in northeastern Minnesota was related to high January temperatures and that predation by wolves (Canis lupus) played a minor role. We found significant inverse relationships between annual wolf numbers in part of the moose range and various moose demographics from 2003 to 2013 that suggested a stronger ro...

Accurate estimates o f kill rates remain a key lim itation to addressing many predator—prey questions. Past approaches for identifying kiU sites o f large predators, such as wolves {Canis lupus), have been lim ited primarily to areas w ith abundant w inter snowfall and have required intensive ground-tracking or aerial monitoring. M ore recently, attem pts have been made to identify clusters o f...

1. Resource selection functions (RSF) have contributed to the conservation of species negatively affected by human activities. Despite these applications, two assumptions frequent many studies: the assumption of independence among groups in social species, and that selection is proportional to resource availability. This latter case is known as a functional response in resource selection, and m...

This paper provides an overview of wolf research in Russia at the beginning 21st century. Wolf covered various directions, including population density estimation, management methods and minimization human-wildlife conflicts, general behavioral ecology, behavior, genetics morphology, paleontology, dog domestication, helminthology wolves’ role rabies transmission. Some studies are performed with...

This paper presents the first prototype of Sheep and Wolves, a system for testing interaction and collaboration paradigms between humans and robots. The paper contributions are twofold: a mixed reality interface for human-robot interaction, and a practical experimental tool for assessing how different robotic behavioral patterns affect interaction and collaboration with users. Sheep and Wolves ...

After centuries of massive decline, the recovery of the wolf (Canis lupus italicus) in Italy is a typical conservation success story. To learn more about the possible role of parasites in the wolves' individual and population health and conservation we used non-invasive molecular approaches on fecal samples to identify individual wolves, pack membership, and the taeniids present, some of which ...

Maned wolves (Chrysocyon brachyurus) are neotropic mammals, listed as a CITES Appendix II species, with a distribution south of the Amazon forest from Bolivia, through northern Argentina and Paraguay and into eastern Brazil and northern Uruguay. Primary threats to the survival of free-ranging maned wolves include habitat loss, road kills, and shooting by farmers. An additional threat to the con...

The grey wolf (Canis lupus) and coyote (C. latrans) are highly mobile carnivores that disperse over great distances in search of territories and mates. Previous genetic studies have shown little geographical structure in either species. However, population genetic structure is also influenced by past isolation events and population fluctuations during glacial periods. In this study, control reg...
