Summary: Neonatal mortality in white-tailed deer is influenced by landscape and physiological characteristics, with human development reducing predation risk but increasing anthropogenic mortality. Smaller birth mass increases the risk of non-predation natural mortality. The study highlights the interaction between landscape attributes, fawn characteristics, and mortality causes.

Summary: Resource selection in sexually dimorphic ungulates is influenced by sex-specific resource requirements and risk aversion strategies. Female white-tailed deer may be forced to utilize high risk areas during high risk periods due to their smaller body size and increased nutritional demands, while larger males are better able to forgo foraging opportunities during risky periods to mitigate risk.

Summary: Predation risk affects intraspecific temporal partitioning in white-tailed deer, where different activity patterns were observed in safe and risky areas. Predators increase heterogeneity in prey behavior and may be important drivers of behavioral processes that minimize antagonistic intraspecific interactions.

Summary: This study investigated the breeding biology of the white-cheeked bulbul in Margalla Hills National Park, Pakistan. The results showed that the white-cheeked bulbul prefers to nest on garanda plants at a height of 1-2m. The average clutch size is 2.6 eggs, with a maximum of 5 eggs. The hatching success rate is 61.7% and the fledging success rate is 67.6%.

Summary: Prey animals' behaviors are influenced by predation risk, and this influence has been observed in wild red-tailed monkeys. The type of vegetation and the antipredator behaviors exhibited by group members also affect the expressions of these behaviors. Different antipredator behaviors are used in different contexts. Measuring only one antipredator behavior may not provide a complete and accurate measure of the perceived predation risk.

Summary: This study examines the effects of multiple predators on the temporal niche of prey, revealing that white-tailed deer fawns minimize mortality risk by avoiding predators during daytime. The study also finds that fawn predation rates in multi-predator systems are similar to those in single-predator systems, which could be attributed to functional redundancy among predators with shared behaviors.

Summary: The population of critically endangered white-thighed colobus monkeys at Boabeng-Fiema Monkey Sanctuary in Ghana is possibly the only growing population of this species in West Africa. The total population growth rate between 1990 and 2020 was 353.9% in the sanctuary and surrounding forest fragments. The population has the potential to further increase in suitable fragments if habitat destruction and settlement expansion are managed with primate conservation intentions.

Summary: Ammospiza caudacuta (Saltmarsh Sparrow) is a critically endangered salt marsh-nesting obligate species. This study used camera traps to document the predation of Saltmarsh Sparrow nests by White-tailed Deer for the first time. The findings have important implications for the conservation and management of Saltmarsh Sparrows.

Summary: The outcomes of predator-prey encounters can impact predation rates and population dynamics. Research in northern Wisconsin showed that increasing snow depth was associated with higher predation risk for white-tailed deer, highlighting the importance of understanding how environmental factors influence predation. As climate change may alter snowfall patterns, such knowledge will be crucial for conservation and management efforts.

Summary: The study found that the mortality of white-tailed deer during winter affects population growth, with factors like temperature and snow influencing the mortality rate. Mortality varies between farmland and forest areas, and human-related mortality is more prominent in farmland regions.

Summary: Increased group size reduces predation risk for individuals and enhances predator detection at the group level. However, the effect of group size on vigilance behaviors varies depending on factors such as season, sex-age status, group composition, diminishing food returns, and intraspecific competition. Our study on white-tailed deer found that the relationship between group size and vigilance patterns is nonlinear and influenced by several interacting factors.

Summary: This study aimed to evaluate pathogen exposure in adult female white-tailed deer and the subsequent survival rates of fawns. The results showed that most pathogens had minimal impact on the short-term fawn survival, but exposure to bovine herpesvirus 1, causing infectious bovine rhinotracheitis, may lower the survival rate of fawns.

Summary: The recovery of the Baltic White-tailed Eagle population since the 1980s is a conservation success story, but their re-establishment in areas with Great Cormorants seems to impact the breeding success of the latter. White-tailed Eagles have been found to have direct and indirect effects on Cormorant colonies, potentially limiting their breeding population size and distribution in some regions as White-tailed Eagle numbers increase.

Summary: Research shows that Coyotes may negatively impact White-tailed Deer recruitment rates by preying on fawns during the summer months. In the Tensas River National Wildlife Refuge, Coyotes exhibited different prey selection between pre-fawning and fawning seasons, leading to changes in consumption patterns of White-tailed Deer and small mammals.

Summary: Seasonal precipitation and temperature change in tropical regions can influence the evolution of polyphenism in Mycalesina butterflies, leading to different reproductive strategies and wing pattern traits in species across different locations. The predictability of environmental factors plays a crucial role in shaping the phenotypic plasticity of butterflies during evolution.

Summary: Comparative studies on insects have shown that larger moth species tend to live longer in tropical communities, and females have slightly shorter lifespans than males. The average adult lifespans and lifespan relationships in tropical geometrid moths are highly similar to those in their temperate region relatives. This suggests that intrinsic physiological factors dominate over extrinsic ecological factors in determining moth longevities.

Summary: The number and diversity of insects on trees are influenced by leaf growth, tree size, genotype, and surrounding tree species. Leaf development and tree growth are related to parasitism pressure and species diversity. Oak tree genotype and phylogenetic distance from neighboring tree species affect the abundance of leaf-mining casebearers. However, contrary to most studies, oak trees surrounded by distantly related trees tend to have higher densities of parasitic insects. The study reveals the factors affecting insect communities on trees.

Summary: Resource use by consumers is often proportional to the quantity or quality of the resource within patches. However, when host trees are isolated among phylogenetically distant neighbors, this proportional use of resources is reduced. Phylogenetic isolation affects the leaf consumption by ectophages, the host use by parasitoids, and the relative abundances of specialists and wingless females. Phylogenetically distant neighborhoods may result in the selection for larger leaves and greater reliance on induced defenses.

Summary: Insect communities in tropical forests have specific structures and vary over time, which is important for biodiversity surveys and conservation assessment. However, generalization is challenging due to limited systematic sampling. In a study conducted in a tropical forest of the Western Ghats, fruit-feeding butterfly communities were compared among different habitats. The study found that canopy specialists were not significantly more abundant than understory individuals, and species diversity was highest in tree fall gaps. The spatiotemporal community structure depended on biogeography and climate.

Summary: Phylogenetically closely related plant species often share similar trait states, but local assembly may favor dissimilar relatives and thereby decouple the diversity of a trait from the diversity of phylogenetic lineages. Associated fauna might either benefit from or suffer from plant trait diversity. We hypothesize that the decoupling of trait and phylogenetic diversity weakens the relationship between plant-trait diversity and the abundance and diversity of associated fauna.
