Summary: The study found that honey bees' use of pollen from prairie plants can depend on the season, with colonies collecting more from nonnative plants in June and July, and more from native plants in August and September. This insight could be useful in addressing honey bee nutritional health, especially during times of forage scarcity in late summer.

Summary: A highly transmissible hoof disease has been observed among wild elk in the western United States since 2008, causing severe lameness and hoof damage, and potentially leading to infection and death.

Summary: This case describes a large unilateral mandibular mass in a free-ranging female adult red deer, which upon pathological examination was diagnosed as odontoameloblastoma with secondary chronic purulent osteomyelitis. Odontogenic tumors are rare in domestic and wildlife species, and this case represents a unique differential diagnosis to be considered when inflammatory lesions mask the presence of a neoplasm in the mandible.

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: 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: Studying the large climatic fluctuations of the last 50,000 years can help understand the effects of climate change on species and their niche dynamics. Paleontological modeling over an archaeological database shows that horse, aurochs, red deer, and wild boar all changed their niche between 47,000 and 7500 years ago, with species-specific responses to climate fluctuations. These species survived the climatic turnovers by being flexible and expanding their niche in response to the extinction of competitors and predators.

Summary: Prescribed burns are important for maintaining prairies, as they affect the diversity of flowering forb plants but not the nectar investment of milkweed plants.

Summary: This study found no association between variation in the myostatin gene and muscle and growth traits in red deer. The results suggest that the myostatin gene in red deer is less variable compared to other livestock species, and its activity may be controlled to maintain a size-growth equilibrium.

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 showed that forest management influences the diet composition of both ungulate species. In areas with high wolf-use, red deer experienced significant changes in diet composition compared to bison.

Summary: This article reviews the history, current population status, and (un)sustainable management of red deer in Lithuania. After extinction in the 19th century, the species was reintroduced during the World Wars and through local translocations. In the past 20 years, the population has exponentially increased, requiring an increase in hunting bag size for sustainable management.

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: The study found that TAHD is associated with epigenetic changes in elk, with infected elk showing systemic epigenetic alterations related to the disease. Despite TAHD pathology usually being limited to the feet, the disease may have impacts on the overall health of elk.

Summary: The study examined the impact of grazing pressure and time since fire on patch utilization and production in experimental grassland pastures dominated by the invasive grass tall fescue. It was found that recently burned patches showed greater initial patch-scale utilization, leading to reduced tall fescue production, especially under high grazing pressure. Although increased grazing promoted native grass production in the invaded grassland landscape, the dominance of tall fescue mediated the lack of structural heterogeneity induced by patch-level prescribed fire and grazing.

Summary: Chronic wasting disease (CWD) is an infectious transmissible spongiform encephalopathy that affects cervids. The spread of the misfolded prion protein (PrPCWD) in various tissues of infected elk was investigated, and it was found that the respiratory system may be the initial exposure route and the autonomic nervous system plays a major role in the spread of the disease. The obex score was proposed as a proxy for disease progression, and key peripheral tissues are recommended for confirmation.
