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: 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: Spatial organization plays an important role in disease transmission, genetics, and demography of wildlife populations. Using hierarchical agglomerative clustering of a spatial graph network, researchers partitioned Wind Cave National Park into five regions used by elk, identified different elk groups based on spatial use patterns, and developed models for variation in chronic wasting disease occurrence. The study found differences in disease prevalence among spatial strata, reflecting varying abundance trends of elk populations in different regions.

Summary: This study estimated the population parameters of the tank goby Glossogobius giuris in the Rabnabad Channel and suggested sustainable management measures. The size at first sexual maturity was 8.5 cm TL. The species had a prolonged spawning season with three peaks and recruitment occurred at 8.2 cm TL with three pulses. The growth parameters, mortality rates, and exploitation rate indicated that the stock of G. giuris was not overexploited and could tolerate increased fishing pressure for maximum benefit.

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: 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 investigated hypodermosis in Cervus elaphus in north-western Spain and found that Hypoderma actaeon is widely distributed in the region. The larvae were observed to have an aggregated distribution among infested animals, and there were seasonal variations in the prevalence and intensity of the infection.

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.

Summary: Identifying and quantifying the vulnerability of threatened populations is crucial for conservation prioritization. The Lahille's bottlenose dolphin population in southern Brazil, particularly in the Patos Lagoon estuary, faces threats from by-catch mortality. Demographic analysis and simulations show high probabilities of viability in the next 60 years under current conditions, with potential decline with removal of mature females. Protection areas and increasing survival rates of juveniles/sub-adults can significantly improve population viability and conservation goals.

Summary: This study aimed to assess the impact of Toxoplasma gondii infection on the reproductive performance of primiparous ewes in southern Australia. The results showed a low frequency of detection of T. gondii seroconversion during gestation and a low frequency of seropositivity to T. gondii, suggesting that toxoplasmosis was not a major contributor to reproductive losses in primiparous ewes on farms located over a wide geographical area in southern Australia.

Summary: The study examines the age-specific pregnancy and survival rates of elk populations and their effects on population dynamics. The results show that pregnancy rates increase with age until reaching a plateau among prime ages, while survival rates plateau among prime-aged animals and decline for the oldest ages. Additional mortality from harvest results in a shift in the age structure towards younger animals with lower pregnancy probabilities. Calf survival rates and pregnancy rates are important factors influencing population growth. The findings provide valuable insights for elk population management.

Summary: Migratory waterfowl play a significant role in the dispersal of zoonotic avian influenza viruses, potentially causing outbreaks in poultry populations. Understanding the movement ecology of waterfowl species that transmit AIVs is crucial in reducing economic impacts on the poultry industry and improving disease surveillance strategies. Movement analysis of blue-winged teal indicates variations in spatio-temporal overlap with poultry facilities, providing valuable insights for biosecurity improvements and disease management in poultry production.

Summary: The use of baited '4-Poster' deer treatment stations has an impact on deer movements, with deer getting closer to the feeders and conspecifics when the feeders are filled. Males tend to use the available feeders more frequently. These behavioral changes, although small, may raise concerns regarding the effects on local deer abundance in the context of infectious diseases and '4-Poster' densities.

Summary: Understanding the ecology and behavior of white-tailed deer in urban and suburban areas is crucial for managing conflicts and preventing zoonotic diseases. This study in Howard County, Maryland used GPS collars to track deer movements and found that factors such as sex, time, and year influenced their speed, activity, and proximity to residential areas. Deer were observed moving into residential areas at night, especially in winter, and showed increased speed and activity after sunrise and sunset, with distinct seasonal changes. These findings have important implications for deer population management and preventing tick transmission to residential areas.

Summary: Highly pathogenic avian influenza virus (HPAIV) H5N1 was introduced in North America in late 2021 through migratory birds. This led to an unprecedented outbreak in animals, particularly affecting poultry and wild birds. The spread of H5N1 in North America highlights the need for effective management and scientific prioritization to address the impacts on wildlife, agriculture, and human health.

Summary: We trapped, anesthetized, and fitted female feral swine with GPS collars in Great Smoky Mountains National Park to develop predictive models for population control. We used Step Selection Function and Resource Selection Function models to evaluate resource selection at different levels for summer and winter seasons. The models showed similar selection levels in summer but differed in winter. We created a consensus model to visualize the agreement and constraints of each set of models. The models can help managers focus surveillance and management efforts on specific areas and seasons.

Understanding the dynamics and prevalence of different viral subtypes, such as H5 and H7, is important for preventing outbreaks in domestic poultry. This study examines the spatial, temporal, and taxonomic drivers of H5 and H7 subtypes in wild waterfowl using a surveillance database.

Summary: Women in conservation science in Indonesia face motivations and challenges, with early-career women citing a love of nature and established career women discussing slowly improving gender norms and the importance of mentors. Without long-term career training and support for underrepresented groups, we risk losing out on novel perspectives to solve ecological problems.
