Summary: The increasing impacts of wildfire on arid regions due to climate change highlight the necessity of understanding the response of natural communities to fire. A study conducted in northern California investigated the use of and diets within burned and unburned habitats by black-tailed deer before and after a large wildfire. The study found that deer increased their use of unburned sites and reduced use of burn sites immediately after the fire, but started returning to burned sites in subsequent years. The diversity of the deer's diet was lower in burn sites post-fire, dominated by oak, but increased in subsequent years with more herbaceous plants in burn sites.

Summary: This study analyzed the impact of different dung availabilities resulting from varying red deer densities on dung beetle assemblages in Central Europe. Results showed that higher dung availability in forest sites led to greater species richness of dung beetles, independently of season, due to different colonization patterns of beetle species.

Summary: Research has shown that protection and foliar overlap have an impact on shrub height, with high levels of protection reducing the proportion of shrubs exhibiting arrested architecture and taller shrubs being more associated with intermediate levels of foliar overlap.

Summary: This study developed quantitative models to estimate habitat selection by black-tailed deer in the west-central Cascade Mountains. The study found that GPS-collar production year, deer activity, and diel period were associated with fix success. To remove fix success bias, the study used a probability of detection integrated step selection function (PDiSSF) to estimate habitat selection. The summer model predictions were satisfactory, while the winter model was less promising.

Summary: Spatial modeling showed that habitat use by female mule deer was influenced by other ungulate species, but competition did not affect their survival and growth.

Summary: Individual factors such as age, weight, presence of pasture, and season have significant influences on the faecal nutrients in captive red deer. These factors need to be taken into consideration when interpreting results from wild samples.

Summary: In a partially forested fenced game reserve in the Netherlands, accurate estimates of red deer population size were obtained through vantage point counts (VPCs) at duplicated sites and compared with population sizes reconstructed from mortality records and field knowledge. VPCs supplemented with vehicular direct counts provided good matches to the reconstructed population size. Simultaneous VPCs at multiple baited sites in forests can yield precise population estimates for red deer.

Summary: Using cellular cameras can significantly reduce the amount of time animals are restrained and lower the risk of negative health effects. Among the benefits, the use of cellular cameras for trap monitoring resulted in a >7 hour reduction in response time to captured deer compared to daily visual trap checks. However, there were occasional camera failures due to drained batteries, inconsistent cellular signal, and photo-processing issues.

Summary: The study found high temporal overlap in water use among feral horses, cattle, and pronghorn in a management area in the western United States, while mule deer and elk showed lower overlap with horses and cattle. Despite the temporal overlap, there was no evidence of interference competition between feral horses, cattle, and pronghorn.

Summary: The study highlights the importance of sport hunting in managing ungulate populations and the influence of landscape features on hunter space use. Successful hunters have smaller core areas compared to unsuccessful hunters, with cover percentage and distance from open roads being consistent covariates affecting space use.

Summary: This study found a positive relationship between physiological stress and testosterone levels in males, especially in populations with high competition level for mating. These results reinforce the idea that this relationship is mediated by male-male competition for mates under natural conditions.

Summary: This study investigates whether opportunistic captures of neonate ungulates bias estimates of litter size and examines the potential causes of such bias. The results show that estimates derived from opportunistic captures are smaller than those derived from movement-based captures or captures with the aid of vaginal implant transmitters. Age at capture is inversely related to litter size estimates, indicating a detection bias associated with opportunistic captures.

Summary: The pursuit of ungulates as game animals is a dominant activity in North America and much of the world. Strategic regulation of hunting is key for managing game population, but knowledge is lacking about hunter characteristics or behaviors linked with success. A 6-year observational study in northeastern Oregon was conducted to characterize hunter traits associated with success for different hunt types.

Summary: Effective wildlife management relies on accurate estimates of animal density, and this study compared three methods for estimating the persistence time of white-tailed deer dung piles. The results showed that differences between observers and the use of the conventional leaf-off method may affect density estimates. The study suggests incorporating interobserver variation and adopting alternative modeling approaches for density estimation.
