Summary: The study found that the activity patterns of snowshoe hares and Canada lynx are not necessarily related to predation risk, and lynx can still prey on hares during the daytime when hares are inactive. This suggests that the overlap of predator-prey activity may not always be a reliable proxy for predation risk, highlighting the need to examine the spatio-temporal behavior of predator and prey to improve our understanding of predation risk.

Summary: In this study, we investigated the diet and prey preferences of the Eurasian lynx in southeast Poland. The results showed that the lynx mainly preyed on roe deer and avoided other ungulates. Additionally, surplus and parallel killing behaviors were observed, indicating the flexibility of lynx in utilizing food resources. The high abundance of roe deer in southeast Poland was found to be crucial for the persistence of the lynx population.

Summary: The study found that food availability and long-term predation risk interactively drive the magnitude of reactive antipredator response to acute predation risk. Determining the factors driving the magnitude of antipredator responses would contribute to a better understanding of the indirect effects of predators on prey populations.

Summary: This study compared the risks imposed by humans and lynx on ungulate foraging behavior, and found that the risk effects of human activities outweighed those of a natural large carnivore. The study also measured browsing intensity, diet quality, and tree species selection to test the hypotheses, and confirmed their validity.

Summary: Camera-trapping and capture-recapture models were used to estimate lynx densities and evaluate demographic parameters at three different sites over five consecutive seasons. Fluctuating densities, high turnover rates, and moderate apparent survival rate were observed, indicating potential human-induced mortalities and population constraints in the Carpathian region. Long-term camera-trapping surveys are crucial for monitoring population trends and implementing effective conservation measures.

Summary: The Eurasian lynx is an adaptable predator that takes ungulates according to their availability, rather than specializing in hunting hares. The predation on large prey is influenced by the density of prey populations and the forest environment. In the wild, ungulates, particularly roe deer, are the main food source for Eurasian lynx.

Summary: Artificial feeding of wildlife has positive and negative effects on both target and non-target species, with potential impact on interspecific interactions. This study used GPS telemetry data to investigate the spatiotemporal response of lynx to artificial feeding sites, and found that experience level played a role in site selection. Experienced lynx tended to avoid feeding sites, while inexperienced lynx were attracted to them, indicating a learning process in response to altered interactions.

Summary: This study examines the strategy of red lionfish in pursuing faster prey. The behavior of successfully capturing prey is defined as the "persistent-predation strategy", which includes pure pursuit, uninterrupted motion, and high success rate in strike.

Summary: The endangered status of African wild dogs in Angola necessitates immediate conservation efforts due to the lack of information and accessibility to the population. This study conducted interviews and camera trapping to assess the distribution and population of wild dogs in Bicuar National Park, highlighting the importance of the park for the conservation of this species and the use of local knowledge for surveying rare wildlife in remote areas.

Summary: The presence or absence of the Iberian lynx has significant impacts on the abundance and spatial avoidance mechanisms of two sympatric mesocarnivores, the stone marten and the common genet. The lynx can reduce mesocarnivore abundance by up to 10 times, with the stone marten completely avoiding the apex predator while the genet persists at lower densities within lynx territories by utilizing its preferred prey.

Summary: The conservation of predators, especially those that pose threats to humans, can cause controversy among stakeholders. However, the ecosystem services and disservices provided by predators through consuming herbivores are often overlooked. Further empirical research into the marginal values of wildlife services/disservices is needed to improve conservation and management outcomes.

Summary: A predator's ability to catch prey depends on its navigation skills in response to prey movements. The pursuit behavior of Townsend's big-eared bat varies, as it relies on a slow and agile flight to stealthily approach prey and reacts to prey movements using a combination of pure pursuit and proportional navigation.

Summary: Carrion, especially in the form of gut piles, is an important but overlooked aspect of food web ecology. The Offal Wildlife Watching project aims to understand how scavenger species benefit from offal and interact with each other. Through citizen science efforts, over 230,000 images of scavengers at deer gut piles have been collected and analyzed. The interactions observed, such as owls and bobcats scavenging and preying on rodents attracted to the gut piles, may have implications for predator-prey dynamics.

Summary: The study found that the numerical response of Eurasian lynx is influenced by both roe deer density and lynx density, indicating the importance of resources and intraspecific competition in understanding lynx population dynamics. Through modeling, cyclic dynamics or dampened cycles were observed in the lynx-roe deer population system.

Summary: Lead poisoning from ingestion of spent lead ammunition is a common cause of death for raptors in Europe, with a varying prevalence among countries. The prevalence is positively correlated with the number of hunters, and scavenging species and predators of hunted birds are more at risk of lead poisoning mortality. Small-bodied predators have a lower probability of death from lead poisoning.
