Summary: This study investigates the foraging behavior of the parasitoid Eretmocerus eremicus in relation to the number of hosts and the risk of predation. The results show that the number of hosts has a significant impact on the parasitoid's behavior, while the risk of predation has a relatively smaller effect.

Summary: This field study on a hybrid zone between Mojave rattlesnakes and prairie rattlesnakes found that hybrids had lower body condition but exhibited similar hunting behavior and diet compared to non-hybrids. The study also found that prairie rattlesnakes were more active at night and abandoned ambush sites earlier in the morning compared to Mojave rattlesnakes.

Summary: The use of odours during carrion exploitation by V. germanica wasps depends on whether they are locating or relocating the resource. Experienced wasps are influenced by olfactory stimuli when food is moved from the learnt location, but ignore odours when returning to the foraging site. This suggests a cue hierarchy where local landmarks are more reliable for relocating carrion.

Summary: By perceiving conspecific chemical cues, damselfly larvae are able to recognize the presence of other cannibals, which provides additional benefits for hunting and defense. However, it is unclear whether these cues inform individuals of danger or food availability in cannibalistic interactions. This study aimed to investigate the response of Ischnura elegans larvae to chemical cues from older conspecific larvae, and found that they exhibit anti-predator defense mechanisms in response to these cues, balancing prey-catching with staying safe.

Summary: Many prey species can assess predation risk through different sensory systems, such as visual and chemical cues. It is unclear whether information from multiple sensory systems is redundant or interchangeable when the message is the same.

Summary: The study found that seasonal ecological disturbances can influence predator activity and create predictable patterns of risk for prey. However, the interaction between human recreation and seasonal risk landscapes and antipredator behavior is still not well understood.

Summary: Comprehensive knowledge of wolf ambush strategies for hunting beavers involves understanding the use of olfactory concealment and proximity to habitat features. This study sheds light on how predators anticipate prey movements and behavior, highlighting the importance of sensory abilities in ambush predation.

Summary: Escape maneuvers are crucial for animal survival and their success depends on the interaction of various parameters like response speed and direction. The intersection of predator and prey volumes in the predatory context determines the likelihood of survival.

Summary: The study in northwestern Taiwan found that wild murid rodents exhibited different behavioral responses to predation risk cues based on their body size and species. These responses were influenced by microhabitat characteristics and predator odors, and smaller and faster species showed more boldness.

Summary: In this study, we used Y-tube olfactometer bioassays to investigate the ability of the Asian egg parasitoid T. mitsukurii to exploit odours associated with the global invader H. halys and with non-target stink bugs native to Southern Europe. We found that T. mitsukurii is attracted to plants exposed to feeding and egg deposition of H. halys and N. viridula, but not to physogastric females or eggs alone. Interestingly, T. mitsukurii is repelled by plants bearing eggs of the beneficial A. custos.

Summary: Foraging involves a trade-off between food and safety, which is often associated with predation. However, danger and risk can arise from various causes and cannot be solely assessed based on predators. To provide a more comprehensive assessment of risk management, this study manipulated and measured risks by adding shelter and time-varying supplemental food to a population of meadow voles. The results showed that voles foraged more actively under safety, recognized least risk with access to both food and shelter, and exhibited sex-dependent habitat selection. This study highlights the need for ecologists to consider other dangers and processes that can alter foraging behavior and habitat selection, rather than attributing risk solely to predation.

Summary: Anti-predation strategies are important for animal survival and understanding predator-prey interactions. Limited studies have been conducted on the anti-predation behavior of nocturnal animals, specifically birds. This study shows that nocturnal passerine birds are not able to detect bats using auditory or visual cues, but instead only exhibit evasive flight behavior when bats approach or touch them.

Summary: Anthropogenic noise and predation risk have concurrent influences on free-living small mammals, affecting their foraging behavior and vigilance. Road noise can increase foraging efficiency but reduce food intake.

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: This study investigated the antipredator responses of two herbivore species and one mesopredator to predation risk imposed by lynx and wolf. The results showed that roe deer avoided lynx urine, hares did not significantly avoid predator urine, and red foxes were attracted to lynx urine in sympatric situations. These findings generally supported the hypothesis of predator avoidance by herbivores and attraction combined with increased vigilance of mesopredators.

Summary: Because animal carcasses often serve as reservoirs for pathogens, their location and removal are crucial in controlling the spread of diseases. Recent studies have shown that infrared sensors can be used to locate animal carcasses, but little is known about the factors influencing detection success. In this study, we investigated the potential of infrared technology to locate wild boar carcasses, as they play an important role in the spread of African swine fever. Our results showed that the thermal camera accurately measured carcass temperature and that the probability of finding carcasses was influenced by environmental and carcass conditions such as habitat type, air temperature, canopy openness, and decomposition stage.

Summary: This study provides evidence for the dominant role played by humans (i.e. hunting, land-use activities) relative to large carnivores in reducing red deer density across European human-dominated landscapes. These findings suggest that when we would like large carnivores to exert numeric effects, we should focus on minimizing human impacts to allow the ecological impacts of large carnivores on ecosystem functioning.
