Summary: The forestry industry is important for providing goods, services, and economic benefits, but timber harvest can have negative impacts on wildlife habitat. This study developed a method to optimize both timber harvest and wildlife habitat suitability, and applied it to Roosevelt elk in Afognak Island, Alaska. The results show that multi-objective optimization can maximize timber harvest yield while minimizing the negative effects on seasonal habitat suitability.

Summary: This study aimed to describe the spatial ecology of red deer in Mediterranean ecosystems of South-Central Spain, showing that red deer exhibited less activity, a shorter daily range, and a smaller home range during the food shortage period. In different land use types, individuals in fenced hunting estates showed the lowest activity and daily range.

Summary: Human-wildlife conflicts, especially with wild ungulates, are a growing problem in the Northern Hemisphere. In order to mitigate these conflicts, preventive measures are necessary to avoid encounters between wildlife and human activities. This study used photo-trapping to evaluate the behavior of red deer when confronted with dissuasive portable deterrents based on changes in light and ultrasound. The results showed that these devices were effective in reducing the frequency of deer use and crossings, but habituation effects were observed.

Summary: The study in Sweden found that red deer exhibit transitional use between arable land and forests, with different crop selection patterns in the North and South areas. In the North, red deer selected arable land while in the South, forest and wetlands were preferred. This highlights the need for regionally-focused knowledge on red deer habitat selection to develop appropriate damage mitigation and wildlife management strategies.

Summary: Research in the Greater Yellowstone Ecosystem has shown a link between elk migration behavior and the risk of brucellosis transmission to livestock. Weather variability impacts the distribution of spillover risk from migrant elk to livestock, with heavier snowfall on private ranchlands increasing the risk of abortions in migrant elk.

Summary: Roads have a significant impact on wildlife connectivity, and the barrier effect of roads is often not fully considered in current assessments. By using Omniscape to model connectivity with and without the presence of roads, this study found that roads have a strong impact on the connectivity of three different wildlife species. The impact is not limited to the roads themselves, but also extends to the surrounding areas.

Summary: Hamartomas are benign tumor-like lesions characterized by disorganized growth of mature mesenchymal or epithelial tissues. They have been sporadically observed in ruminants, with pulmonary and cutaneous forms reported in sheep and vascular, fibrous, nasal, and pulmonary forms reported in calves. This article presents a case of pulmonary hamartoma found in a full-term elk calf, which has not been previously reported in non-domestic ruminants.

Summary: Ungulate-vehicle collisions in Europe are increasing, posing a risk to human safety and causing animal deaths. This study found that the factors influencing collisions varied between species, including land use, cover, water availability, movement corridors, population density, and road topology. The interaction between urbanized and forest areas showed a high-risk for collisions. Mitigation actions should focus on reducing attractiveness and abundance of ungulate populations, and awareness campaigns and species-specific signalling may also help decrease casualties. Further data collection is crucial for assessing local predictors.

Summary: The study analyzed the effects of prescribed burns informed by traditional ecological knowledge on elk winter habitat in Karuk aboriginal territory in Northern California. The results showed that burns closely resembling Karuk traditional practices had positive effects on elk winter habitat suitability, while concentrated burns solely focused on fuel reduction had negative effects. Combining fuel-reduction burns with multiple years of broadcast burns resulted in the highest increase in habitat.

Summary: Anthrax, caused by the spore-forming bacterium Bacillus anthracis, is a global zoonosis affecting animals and humans. In the United States, outbreaks occur in wildlife and livestock in various states, with sex-specific resource selection and habitat use leading to differential anthrax exposure risks for male and female ungulates. Understanding the spatial distributions of potential anthrax exposure for different sexes can improve anthrax and wildlife management, with important implications for public health and economics.

Summary: A new foot disease of unknown origin was discovered in captive European Bison at Berne Animal Park. The disease, diagnosed as dermatitis of the interdigital cleft, was found in all examined animals and was characterized by varying degrees of severity in skin lesions, with the presence of viable spirochaetes identified in all cases.

Summary: This discovery suggests a new parasite in Sierra Nevada National Park, indicating significant changes in climatic conditions which may be better suiting the environmental requirements of this bot fly. Monitoring the presence of this parasite could be helpful in detecting signs of global change.

Summary: Babesia odocoilei is a tick-borne protozoal parasite that infects the erythrocytes of white-tailed deer and bovids, potentially causing hemolytic anemia and death. While the reservoir host is white-tailed deer, cases of overt disease have been documented in reindeer, caribou, and captive elk.

Summary: Success in conserving biodiversity in rangelands depends on effectively managing the systems to achieve positive economic outcomes while preserving biodiversity. This study found that managing grass height can increase forage mass without replacing native vegetation. However, the impact on grassland bird populations remains unclear. The findings suggest that maintaining grassland bird specialists and potentially increasing livestock production is feasible, but longer time frames may be needed to support endangered tall grass specialists.

Summary: This study aimed to analyze the impact of Turkmen pastoralists' participation in rangeland restoration practices in Aqqala County. The results showed that pastoralists' age, annual income, number of animals, and animal husbandry experience had positive relationships with participatory behavior. Pastoralists who were members of rangeland management cooperatives and participated in training courses performed better in implementation. By identifying the consequences of participatory behavior, barriers to participation in restoration practices can be overcome.

Summary: The distribution of Wyoming big sagebrush has decreased due to its interaction with invasive annual grasses and increased wildfire frequency. Traditional seeding methods have low success rates, while transplanting sagebrush has a higher success rate. Planting younger transplants and controlling invasive annual grasses before planting can increase transplant survival and canopy volume.
