Summary: This study used a Bayesian network to predict the habitat suitability of mountain goats in the Canadian Pacific region. The results showed that steep slopes, forest cover characteristics, and snow depth were important drivers of habitat suitability for mountain goats.

Summary: This study examines the patterns of adult survival rates in mountain goats and their relationships with biotic and abiotic factors. Results show that survival is influenced by factors such as winter snow depth, drought index, temperature, and precipitation. These weather effects have contributed to a reduction in mountain goat survival and may pose a challenge to their population stability in the future.

Summary: Anthropogenic activity puts increasing pressure on wildlife populations, affecting habitat and population viability. This study used GPS collar data to develop resource selection function (RSF) models for identifying important habitat for native mountain goats. The models, when combined with aerial survey data and existing methods, improve the accuracy of delineating ungulate winter ranges in similar eco-regions.

Summary: Variation in age of primiparity affects population growth. Through a novel technique, we estimated the age of primiparity for 2274 mountain goats and studied the spatio-temporal variation in primiparity probability. Results suggest that large coastal mountain goat populations may be more resilient to harvest.

Summary: The study investigated the use of thiafentanil as an alternative to carfentanil for chemical immobilization of mountain goats, finding that thiafentanil had faster induction and recovery times compared to carfentanil, but similar immobilization characteristics.

Summary: This study reveals a decline in mountain goat population and habitat use in the Kitasoo Xai'xais (KX) territory in British Columbia. It emphasizes the importance of local knowledge and decentralized management in detecting and addressing threats to wildlife populations.

Summary: Understanding the spatial use patterns and range fidelity of mountain goats in coastal Alaska revealed distinct seasonal and sex-specific variations. Females had larger home ranges than males during summer, but this relationship switched during the mating season. The high degree of range fidelity among individual animals, with 99% of them returning to their previous year's seasonal range, has important conservation implications in landscapes increasingly altered by human activities.

Summary: Obtaining field data and analytical methods for wildlife population conservation and management are significant challenges, especially for species in difficult-to-reach landscapes or small, isolated populations. Integrating genetic and non-genetic data can enhance understanding of population dynamics. Studying a low-density mountain goat population, genetic and morphologic data indicated demographically isolated peninsular subpopulations and influenced sustainable harvest quotas. The importance of using genetic and morphologic data, along with demographic modeling, in delineating population boundaries and dynamics for small, isolated populations was highlighted.

Summary: The potential negative artificial selection on horn size is a concern for hunting mountain goats. This study found that geographical location and artificial selection have little effect on horn size, while climate conditions may play a significant role. Additionally, mountain goats harvested closer to roads tend to have larger horns, possibly due to hunters' increased selectivity.

Summary: The study compared the results of aerial thermal infrared (TIR) and helicopter surveys for estimating bison populations in Grand Canyon National Park, USA. The TIR survey was more expensive and resulted in lower estimates compared to the helicopter survey. Despite the small sample size, it was found that helicopter surveys are currently the best method for estimating bison abundances in dense canopy cover areas.

Summary: This article discusses the challenges of estimating abundance for low-density, unmarked species and introduces a method that combines a probability-based survey design and statistical models. By using an N-mixture model with spatially balanced random sampling and double-observer data collection, the approach directly addresses the problem of approximating statistical assumptions and provides unbiased estimates.

Summary: This study describes human-mountain goat interactions in Cathedral Provincial Park in Canada and examines management and mitigation strategies to reduce these interactions. The results indicate that although most respondents encountered mountain goats in the park and understood the park's messaging, not all took the necessary steps to reduce encounters. Further education efforts, staff training, and improved infrastructure are recommended. The findings can inform management decisions related to human-wildlife interactions in parks and protected areas.

Summary: This study aims to develop a new platform for monitoring marine ecosystems and conducting automated bio census, particularly for birds. Through the use of several hybrid techniques, the platform is able to accurately detect and separate maritime species, specifically birds, to achieve automated censuses in highly dynamic marine ecosystems. The experimental results demonstrate high sensitivities, specificities, and accuracies in the detection and separation of seabirds, and the proposed techniques have been validated by evaluators.

Summary: Waterbirds are important indicators of wetland health, but surveying certain species can be challenging due to their sensitivity to disturbance. This study used drones with dual visible-thermal cameras to accurately count nests of marshbirds in Saskatchewan, Canada. The results showed that drone-based counts were within 5% of ground-based counts, with no significant disturbance detected during drone surveys.
