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: 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: Research on gray wolves found that males are more likely to be adopted into breeding positions outside their group, while females typically inherit breeding positions within their natal groups. Group size does not influence whether a breeding vacancy is filled by an adoptee or inherited by an individual from within the group. Genetic relatedness within groups appears to play a role in whether females are adopted into groups or not.

Summary: Wolves can be domesticated due to their sociality, varied diet, excellent memory, inbreeding tolerance, different personalities, and adaptable lifestyle. However, their fear of humans is a major obstacle to domestication, but collecting young pups and raising them can help in socializing them with humans.

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: The study found that slow freezing better maintained the morphology of cryopreserved testicular tissues compared to needle vitrification, and the combination of DMSO + EG in slow freezing supported cell viability.

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: Research on reproductive variables of wolves in Spain found that the majority of adult females were pregnant, with an average litter size between 5.54 and 6.00; observations indicated that the main mating season was estimated to occur between February and March.

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: 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: Age at first reproduction is a key life-history trait in animals, shaped by fitness benefits and costs of delayed versus early reproduction. Research shows that in Scandinavian wolf populations, female age at first reproduction decreases with increasing population size, while male age at first reproduction increases with population size.

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 aimed to assess the impact of population size changes and migrations on functional immunity genes in grey wolves. High genetic variance in immunity genes and weak population structure were found, suggesting migrations do not cause allele loss in wolves. Selection signatures on codon level indicate the contrasting effects of demography and selection.

Summary: This study provides historic estimates of survival and abundance of common bottle-nose dolphins based on photo-identification surveys in coastal Venezuela. The marked adult dolphin survival rate was estimated at 0.99, with an average population estimate of 31 adults and 41 dolphins overall. The study highlights the threats faced by coastal bottlenose dolphins and the need for ongoing monitoring and conservation efforts for this small population.

Summary: The study found that wolves captured in wilderness areas tend to have a higher survival rate compared to those captured in non-wilderness areas, especially during harvest and post-harvest years. Non-wilderness wolves had higher rates of anthropogenic and illegal mortality. Wilderness wolves were less likely to die, pups were more vulnerable than adults, and males were less likely to die compared to females.

Summary: This study evaluated whether a suite of non-invasive methods could replace aerial radiotelemetry to census resident pack wolves. The results showed that ground snow-tracking and camera-trapping provided the most similar information to radiotelemetry for determining pack counts and territory information. Non-invasive methods allowed for a reduction in trapping, increased the annual wolf-count precision, and increased community involvement.
