Summary: This study investigated the response of Andean condors to predation risk and found that they searched for carrion in areas where pumas had killed camelids. However, condors avoided exploiting carrion in areas with high vegetation and steep slopes, indicating that they primarily manage risk by identifying safe foraging sites.

Summary: This study demonstrates that fear itself can significantly impact prey population growth rates in free-living wildlife, potentially constituting a considerable part of the total impact of predators.

Summary: This study examines the ability of anuran larvae to detect predation risk through indirect cues from conspecifics exposed to predator stimuli. The results show that larvae can perceive and respond to predation risk based on cues from conspecifics, indicating the importance of cognitive abilities in predator-prey interactions.

Summary: Understanding the ecology of fear in ungulates is crucial for ecosystem conservation. However, there is controversy and bias in the existing literature, with a focus on North American species such as elk and gray wolves. Some studies suggest that utilizing predation risk can be beneficial for conservation, but the population-level fitness consequences and cascading effects of fear-related physiological changes remain unclear and require further research.

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: Early detection plays a crucial role in a prey’s survival when facing ambush predators. While social prey benefit from cues provided by conspecifics, individuals who do not detect a threat are still at risk of attack. Factors such as habitat visibility, scanning behavior, and group spatial cohesion varied in importance depending on the predator species encountered, indicating that the effectiveness of risk-sensitive strategies in social animals is contingent upon the type of threat.

Summary: Chemical information plays a vital role in the sensory ecology of aquatic species, including alarm cues and disturbance cues. This study used wood frog tadpoles to demonstrate that repeated exposure to disturbance cues during the embryonic stage can induce neophobic behavior, while disturbance cues do not serve as associative learning cues.

Summary: During biotic invasions, native prey may struggle with recognizing and responding to novel predators, but mechanisms exist to help prey overcome evolutionary naivety. Studies have shown that different amphibian species exhibit varied behavioral responses to cues associated with an invasive predator, with species that share coevolutionary history with native predators showing more refined responses to the invasive predator.

Summary: The study found that cannibalism by male Macrolophus pygmaeus significantly reduced the number of hatched eggs, posing a greater risk to mirid eggs than intraguild predation. Female M. pygmaeus responded to potential intraguild predators by laying fewer eggs on upper leaves, indicating a strategy to avoid competition. Cannibalism could potentially regulate zoophytophagous predator populations and minimize crop damage risk associated with these biological control agents.

Summary: Predator-prey dynamics play a crucial role in the natural structuring of communities, with our study revealing that predation risk in semi-arid environments is more influenced by seasonality rather than habitat structural complexity. Specifically, the overall attack rate was found to be 19% higher in the dry season.

Summary: In this study, three anuran species were tested for their response to territory songs and alarm calls of Japanese Tits. The results showed that all species did not exhibit any response. Although the findings were negative, the study provides valuable information about the cognitive processes of amphibian species.

Summary: The study on croaking gouramis revealed that fish reduce visual and acoustic signaling in the presence of predators, avoiding escalating fights to lower predation threat. The fish showed approaching behavior towards predators during contests, and contest outcomes were decided during lateral displays rather than escalating to frontal displays.

Summary: Many animal species protect their eggs against predators, and some species take advantage of this by adding their eggs to those of the protecting species. We studied two tiny predatory mite species that share a food source and face intraguild predation, and found that one species acts as a brood parasite by adding its eggs to the eggs of the other species. The brood parasite prefers to add its eggs to the eggs of the protecting host species rather than another non-protecting mite species, and this behavior only occurs in the presence of egg predators.

Summary: Predation is a psychological stressor for prey animals, influencing their behavior, dynamics, and physiology. Using gene expression data from wild yellow-bellied marmots, it was found that female marmots had a higher number of differentially expressed genes in response to predator stress compared to males. Only a small percentage of these genes were shared between the sexes, with most of the differentially expressed genes being expressed in a sex-specific manner.

Summary: This study evaluates the frequency of eHealth use, perceptions of eHealth literacy, and views on patient-provider relationships among undergraduate students. The findings show that students commonly use eHealth but are skeptical of telehealth appointments. While they feel capable of finding and interpreting eHealth sources, they lack strong confidence in their ability to do so. Students desire their physicians to act as counselors or advisors rather than just guardians. Additionally, minority students are more likely to use eHealth and student comfort with their providers varies by race, ethnicity, and gender identity.

Summary: Service-learning is an experiential learning approach that connects course content with community needs. This study incorporated service-learning into a plant biology course and examined the differences in plant biology knowledge, classroom community connections, and self-efficacy for environmental action between service-learning participants and non-participants. The findings showed that service-learning students had a slightly increased sense of community with their peers but did not perceive a higher ability to be agents of social change.

Summary: In this study, the Argument-Driven Inquiry instruction model was implemented in a two-semester sequence of introductory biology laboratories. The results showed that students scored significantly higher on the social aspect of argumentation compared to the cognitive and epistemic aspects. Additionally, the design and implementation of the lab exercises affected the level of argumentation that occurred. These findings contribute to the development and improvement of Argument-Driven Inquiry instructional models, aiming to enhance students' scientific argumentation skills and understanding of science.

Summary: Successful mentoring relationships are important for the success of mentees, especially in underrepresented populations. This study investigated the mentoring experiences of medical students and found that race and household income impacted their access to informal mentors. The strength of the mentees' goals for mentoring was positively associated with the number of formal mentors they had.
