Summary: This study presents the first evidence of Hepatozoon canis in grey wolf populations in Serbia, highlighting the high prevalence and genetic diversity of the pathogen. Further research is needed to understand the transmission mechanism, potential sources of infection, and the impact of this pathogen on wild carnivores.

Summary: This study aimed to confirm the presence and molecular identification of Echinococcus tapeworms in wolves from south-eastern Poland. The investigation revealed the presence of adult E. ortleppi tapeworms in wolves for the first time, with PCR and sequencing showing high similarity to E. ortleppi (G5) sequences.

Summary: Research on grey wolf dispersal patterns has shown high variability and is influenced by individual, social, and environmental factors, with human-caused mortality, population density, and interactions with humans impacting dispersal. Methodological issues have been identified that hinder obtaining robust estimates of dispersal parameters and patterns. Reporting results and potential factors affecting wolf dispersal more transparently could significantly benefit wolf biology and management understanding.

Summary: Long-term monitoring of wolf population in northwest Portugal showed an average annual population size of 27 individuals, with a growth rate following a decline and recovery pattern. Dispersers accounted for 11% of the population with an average dispersal distance of 24.8 km, while core packs demonstrated higher group persistence, breeding success, and average group size compared to sink packs.

Summary: Coyotes are effective seed dispersers, capable of providing regular long-distance dispersal services and opportunities for secondary seed dispersal, which could aid in climate migration or serve to replace extirpated dispersal mutualists.

Summary: Genetic diversity decreases in populations closer to a species' range edge, but generalist species capable of long-range dispersal can counteract this. However, presence of significant barriers to dispersal may still lead to and exacerbate the edge effect.

Summary: The study aimed to develop an updated distribution model and habitat suitability analysis for the Mexican wolf, with results showing suitable habitat extending from central Arizona and New Mexico to high sierras of Oaxaca, Mexico. Large tracts of high-quality habitat were identified in the southwestern United States and Mexico, indicating potential for recovery within the historical range of the Mexican wolf.

Summary: This study detected the presence of Neospora caninum, the leading cause of reproductive failure in cattle and severe neuromuscular disease in dogs, in wild canids in Slovenia. The prevalence of infection was 7.1% in gray wolves and 2.6% in golden jackals. This is the first molecular detection of the parasite in gray wolves in Slovenia and the first detection in golden jackals. The findings suggest that golden jackals may act as a potential definitive host and influence the spread of N. caninum in livestock.

Summary: This paper presents a case study on estimating the population density of the Iberian wolf using video camera traps and spatially explicit capture-recapture (SCR) analyses. The study estimated a density of 2.88 wolves/100 km² in the study area.

Summary: This study compared the ability of different connectivity approaches, using home range and dispersal data, to predict lion movement. The results showed that all approaches performed well in predicting dispersal, with cost-distance approaches being more sensitive to resistance input. Home range data can be used to generate resistance surfaces for connectivity maps, and independent dispersal data can be used to determine connectivity thresholds for delineating corridors.

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: Larval exchange among marine populations is important for population dynamics and conservation actions. Accurately measuring dispersal remains challenging, but this study shows that indirect methods based on isolation-by-distance (IBD) can produce accurate dispersal estimates in the coral reef fish Elacatinus lori. These estimates were compared to direct measurements from genetic parentage analysis, and the results suggest that the IBD method may be broadly applicable to studying marine larval dispersal.

Summary: This study quantified the triggers and consequences of wolf howling events in Yellowstone National Park. The results supported both theories of animal communication, showing that howling is not only about transmitting detailed information but also about communicating emotional/motivational states. The study also revealed the flexibility and social discrimination in the use of wolf howling.

Summary: The study shows that land use and environmental distance are the most important factors explaining community dissimilarity for most of the different dispersal traits of stream macroinvertebrates. At the local scale, environmental filtering was the most important community assembly mechanism, while land use could constrain dispersal at the regional scale.

Summary: This study reviewed existing literature on barriers to connectivity in European wolf populations. The analysis suggested that anthropogenic features are the main drivers of barrier occurrence, but the lack of standardized data limits our understanding of this issue. Long-term monitoring programs and empirical research are needed to increase the conservation and management relevance of future scientific outcomes on this topic.
