Summary: Prosocial behavior is common among group-living mammals, and Canidae are known for their social organization. This case study focused on social feedback mechanisms in two groups of grey wolves, and found that bold behavior is more likely to receive prosocial responses.

Summary: This study investigates the migratory coupling between grey wolves and migratory caribou in northern Canada. The findings indicate that the movement patterns and space use of wolves are related to the seasonal distribution of caribou, and there is overlap between the home ranges of wolves and the areas used by caribou. The results are important for the conservation and management of both species in the context of declining migratory prey.

Summary: This study compared stable isotope evidence from British fossil wolves, carnivore competitors, and potential prey species from three different time periods. The results showed clear patterns of changing wolf prey choice over time, with the diet of wolves shifting from small and large prey during MIS 7c-a to large prey only during MIS 5a and a broader range of large prey during MIS 3. The study also revealed a lag between changing predatory behavior and morphological response in wolves.

Summary: The demands of raising dependent young can influence the feeding behaviors of social carnivores. In gray wolves, breeding individuals prioritize meeting their own energetic demands over those of their pups. These behavioral patterns adjust according to prey abundance.

Summary: This study focuses on the grey wolf recolonization in Germany and compares the performance of different distribution modelling approaches for predicting habitat suitability in unoccupied areas. It also analyzes the non-stationarity in habitat selection of the grey wolf in newly colonized areas.

Summary: To address the conflict between humans and wolves, a reliable method is needed to identify predators and determine compensation. By analyzing and comparing tooth marks caused by wolves and dogs, it was found that wolves had more modifications but there were also overlaps between the two. Therefore, the interpretation of tooth marks found at crime scenes must consider multiple factors. By utilizing novel image processing and statistical analysis, it is possible to identify morphological and/or morphometric variables for taxonomic differentiation.

Summary: The gray wolf population in Isle Royale National Park has experienced a drastic decline, with only two remaining wolves in 2017. To restore the ecosystem, 19 gray wolves were translocated from different regions, with the majority coming from a single family group from Michipicoten Island. The founders were genetically diverse but may face challenges related to genetic variation and inbreeding in the future.

Summary: This study examines the ecology and behavior of wolves in the Hindukush-Himalayan region and finds that they primarily feed on domestic prey, but also consume wild prey. The study reveals that a majority of respondents perceive wolves as a potential threat to livestock. Using ecological and social information, the study identifies hotspots where conflicts between wolves and humans are most likely to occur. The study suggests that negative perceptions toward wolves can be addressed through a comprehensive conservation action plan and integration with local traditions.

Summary: Studies show that coyotes do not universally avoid wolves, but exhibit season-specific responses to wolf proximity and long-term landscape use by wolves. They avoid wolves in summer but prefer areas with wolves in winter, suggesting that mesopredators employ complex behavioral strategies to mediate apex predator effects.

Summary: In the last few decades, there has been a significant recovery and natural expansion of wolf populations in Europe. This study focused on the movement patterns of rehabilitated wolves in a highly human-dominated landscape in Northern Italy. The results showed that wolves had the ability to segregate from human activities and exhibited different movement patterns based on their settling or dispersing phases.

Summary: Carrion competition among carnivores, dominated by wolves and wolverines. Scavenging animals reduce risk exposure primarily by reducing carrion use, with some evidence of increased vigilance. Intraguild competition strongly affects which species benefit from carrion.

Summary: Chemical signals in wolf feces, including aromatic compounds, steroids, and tocopherol, vary in composition and proportions between sexes and reproductive states. These compounds likely play a role in intraspecific and interspecific communication, and their levels in feces may be indicative of the wolf's sex and physiological and reproductive status.

Summary: The study combined wolf scat data from three different regions within the Greater Yellowstone Ecosystem to examine the summer diet of wolves, finding that neonate cervids, adult elk, and adult deer were the most important prey species. The research revealed dietary variation among wolf packs within the same area, across different years, and between regions, indicating flexibility in summer diet across packs, years, and regions within the ecosystem.

Summary: Gray wolves are recolonizing central Europe but roads may hinder their reestablishment, increasing mortality from wildlife-vehicle collisions. Green bridges could mitigate road impacts and increase landscape connectivity for wolves and prey species. Research shows that both wolves and prey species use green bridges, potentially enhancing their recolonization in rewilding landscapes.
