Pathogens, Nutritional Deficiency, and Climate Influences on a Declining Moose Population
Analysis of protein content in moose browse and fecal samples indicated that food quality was probably adequate to support moose over winter, but the higher fecal protein among animals that died in the subsequent 18 months could be indicative of protein catabolism associated with malnutrition, which may have contributed to moose mortality.

Development of predictive models of nutritional condition for Rocky Mountain elk
Several indices of condition useful for assessing nutritional condition of live or dead elk are identified, and a number of previously used techniques that correlate poorly with total body fat are indicated. Expand
Estimating low-density snowshoe hare populations using fecal pellet counts
The number of hares occupying intensive study sites was correlated with pellet density on all plot types, but rectangular plots provided a slig... Expand
The data show that the two similarly sized predators differed in their foraging behavior and relative abilities at capturing alternative prey, leading to different patterns in their functional responses to fluctuations in the density of their preferred prey. Expand
Spatial organization and food habits of jaguars (Panthera onca) in a floodplain forest
For most carnivore populations, territoriality is the regulating social system ultimately determined by food abundance and/or strife. However, in some food-based territorial felid species such as theExpand
Effects of Variable Sampling Frequencies on GPS Transmitter Efficiency and Estimated Wolf Home Range Size and Movement Distance
Abstract Global positioning system (GPS) technology has greatly improved the ability to investigate animal ecology at fine spatial and temporal scales but many GPS telemetry-based investigations mayExpand
Infectious disease and the conservation of free‐ranging large carnivores
It is concluded that the threat of disease epidemics in large carnivores may be serious if otherwise lethal infections are endemic in reservoir hosts and transmitted horizontally among taxa. Expand
Assessing differential prey selection patterns between two sympatric large carnivores
It is concluded that the disparity in prey selection and hunting habitat between predators probably was a function of predator-specific hunting behavior and capture success, where the longer prey chases and lower capture success of wolf packs mandated a stronger selection for disadvantaged prey.

On Improving Telemetry-Based Survival Estimation
Telemetry-based survival estimation will benefit from increased emphasis on modeling approaches designed to elucidate survival determinants in complex systems, combined with more rigorous attention to basic assumptions and study design limitations. Expand
Assessment of Canada Lynx Research and Conservation Needs in the Southern Range: Another Kick at the Cat
Abstract The ecology of Canada lynx (Lynx canadensis) and their main prey, snowshoe hares (Lepus americanus), is poorly understood in southern Canada and the contiguous United States compared to theExpand
