Summary: Island ecosystems provide natural laboratories for studying the impacts of isolation on population persistence. In this study, the genetic variation and population trajectories of moose and gray wolves on Isle Royale are compared. The moose population has thrived and persisted despite low genetic diversity and isolation, while the wolf population nearly went extinct due to severe inbreeding depression. The study highlights the complex relationship between inbreeding, genetic diversity, and population viability in isolated populations.

Summary: Parasitic infections have a negative impact on fecundity and survival of wild ruminants, particularly moose. This study aimed to identify gastrointestinal and liver helminth species of moose in central Europe, finding a variety of parasite taxa with higher diversity and infection intensities in adult moose. The study also revealed that parasite infections can lead to histopathological changes, especially in the livers of infected moose.

Summary: Landscape characteristics, environmental changes, and daylight conditions influence the spatial and temporal patterns of predation risk for prey. Humans have become super-predators in anthropogenic landscapes. This study investigated the influence of environmental and anthropogenic features on the locations of wolf and hunter kills on moose. The results showed contrasting spatial and temporal patterns of risk for wolves and hunters, indicating that moose can minimize risk exposure by utilizing vacant hunting domains.

Summary: The survival of juvenile ungulates has a significant impact on population dynamics in ecosystems. This study analyzed the relationship between the survival of moose calves and factors such as carnivore occurrence, habitat productivity, weather, human harvest, and migratory behavior. The study found that regions with higher bear densities had higher calf mortality rates, and calf survival was lowest in the presence of wolves and deep snow. Calf survival was also negatively correlated with the proportion of clearcuts and young forests within the mother's home range. Additionally, calves of stationary females had higher survival rates compared to migratory individuals.

Summary: In this study, a mechanistic moose population model was developed using hunter observations data in Sweden, estimating the moose population size change trends from 2012 to 2020. The results showed a 15% nationwide decrease in moose abundance during this period, with the northern and northernmost regions having the highest density.

Summary: The study found that the population dynamics and reproductive output of wild forest reindeer were influenced by the abundances of wolves and moose, supporting the alternative prey hypothesis. However, the study also acknowledged that the alternative prey hypothesis and apparent competition hypothesis are not mutually exclusive, and the management of the entire ecosystem is crucial for the recovery of wild forest reindeer.

Summary: In this study, remote sensing and machine learning methods were used to explore the habitat associations and suitability of moose in Northeast China. Results showed that human disturbance and heat stress were the main drivers of moose occurrence, and high suitability areas were mainly distributed in the eastern and northern parts of the Greater Khingan Mountains.

Summary: Forest management can enhance ecosystem services but also alter their capacity. Ecosystem-based management has been implemented to reduce differences between managed and natural forests. Moose browsing could interfere with the objectives of maintaining community composition, stand structure, and ecosystem functions. An experiment in boreal forests of Quebec showed that moose browsing indirectly increased deciduous seedling densities while reducing coniferous sapling densities. This interference could prevent the achievement of ecosystem management objectives.

Summary: Given the recent decline in the abundance of moose, this study reconstructed the population trends and demographics of moose in northeastern Minnesota from 2005 to 2020 using statistical population reconstruction. The analysis confirmed the sharp decline in abundance in 2013 and predicted a modest decline in the next 10 years.

Summary: This article reports the first observation of coprophagy in moose in Norway, using camera collars. It summarizes the current knowledge about coprophagy in deer and discusses potential drivers and implications for disease transmission. Further research is needed to determine the frequency of coprophagy in moose and its impact on nutrition intake and infection risk.

Summary: This study presents a method for estimating landscape carrying capacity of moose by combining remote sensing classification and literature or field-based estimates. The results show that this method can accurately identify forest timber treatments and provide an alternative method for estimating landscape-level ungulate carrying capacity.

Summary: Human-caused landscape disturbance, such as industrial forest harvesting, has led to changes in forest structure and composition, affecting the diet composition and diversity of moose populations in central British Columbia, Canada. The Niche Expansion Hypothesis and the Niche Shrinkage Hypothesis were tested to determine the effects of logging and other disturbances on moose diet.

Summary: Wild moose actively regulate the nutritional composition of their rumen to offset variations in available food sources, with a consistent proportional relationship between protein and nonstructural carbohydrates. Rumen macronutrient balance is closely linked to dietary fiber intake, suggesting moose benefit from a diverse diet for nutritional flexibility.

Summary: A study on Swedish moose populations revealed significant impacts of climate change on calf mass and recruitment. As temperatures rise and extreme weather events increase, moose are becoming more sensitive to heat stress and hot, dry conditions, affecting recruitment.

Summary: By combining aerial surveys and density surface modeling, this study successfully estimated the distribution, abundance, and trend of moose in northern New York. The results showed that moose abundance was positively related to active timber management, elevation, and snow cover, while negatively related to large bodies of water. The density of moose in New York's peripheral population was lower compared to its core range, but approached levels where epizootics of winter tick have been reported in certain areas.

Summary: Habitat-selection analyses and integrated step-selection analyses are useful for linking animals to their environment, commonly used in wildlife management and conservation. However, many users struggle with interpreting parameters in these analyses, and using weighted distribution theory and Poisson point process can facilitate parameter interpretation.

Summary: This study developed an integrated modeling framework to classify states and quantify transition risk in ecosystems exhibiting alternative stable states, helping inform conservation and management strategies. For shallow lakes, it was found that clear lakes were more likely to transition to turbid states as total phosphorus levels increased and submerged vegetation decreased.
