Summary: This study examines the impacts of ocean acidification on tidepool communities, focusing on the interactions within a three-level food web. The results show that experimental declines in seawater pH suppress the anti-predator behavior of snails, leading to a diminished top-down control of predators on basal resources. These findings suggest that ocean acidification may alter cascading effects within food webs.

Summary: Predators can impact population and community dynamics through direct predation and nonconsumptive effects, such as changes in prey species traits. However, little is known about how kairomones act on prey across diverse aquatic ecosystems. This study explored how predator and prey identity and species composition influenced the expression of inducible defenses in water fleas.

Summary: The study showed that predation stress reduced the cellular metabolism and increased protein storage in G. paganellus. Additionally, hyperthermia decreased aerobic mitochondrial metabolism, indicating thermal compensation mechanisms. Thermal stress was the dominant stressor overriding responses to predation stress.

Summary: Predation risk leads to various responses in prey, including changes in life history and habitat shifts. Metabolism, being a ubiquitous trait, provides a way to study the effects of predators and generate generalizable outcomes. In this study, we examined the metabolic responses of different functional groups of terrestrial and aquatic prey to predator cues. We found that constitutively defended prey did not show any metabolic responses, while deimatic and freeze-flight prey exhibited cue type and predator hunting mode-dependent metabolic responses. Consistent with previous research on nonconsumptive effects, ambush predators elicited metabolic responses, while active predators did not. We propose that future research should continue to use a metabolic approach as a unified, scalable response variable to study the sensory ecology of nonconsumptive effects and identify additional systems to evaluate predator hunting mode and prey antipredator defenses more comprehensively.

Summary: This paper discusses the solutions of a quasilinear predator-prey model with indirect prey-taxis under specific conditions, proving the existence of a unique global classical solution that remains uniformly bounded in time. Additionally, the asymptotic behavior of globally bounded solutions in the system is derived based on different predation conditions.

Summary: Understanding the factors controlling decomposition is crucial for predicting changes in the carbon cycle with global change. Ants exert significant top-down control on decomposition by preying on termites, leading to increased termite-mediated decomposition at a large scale.

Summary: The assessment of individual costs of anti-predator defense is limited due to the modulation of prey responses by additional factors commonly present in the environment. This study shows that external factors such as conspecifics and darkness can reduce the costs of predator non-consumptive effects compared to laboratory conditions.

Summary: The indirect interactions between a focal and alternative resource mediated by a generalist consumer can be influenced by associational effects, resulting in various dynamics such as apparent competition and apparent mutualism. The inclusion of density-dependence expands the range where alternative resources positively influence the focal resource.

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: The influence of indirect prey-taxis on the dynamics of a predator-prey system with predator functional response is studied. The study analyzes the stability and bifurcations of the system, deriving critical values of the indirect prey-taxis coefficient. The research finds that attractive indirect prey-taxis can destabilize the system and induce the emergence of spatially inhomogeneous periodic solutions. The secretion level of chemoattractant by the prey plays a role in determining the likelihood of spatial patterns.

Summary: Mutation supply can influence evolutionary and ecological dynamics by affecting population size and species interactions, particularly when population size is constrained by external conditions. Controlled experiments show that higher mutation supply enables faster adaptation to low-resource environments and anti-predatory defense mechanisms, leading to increased population size and better access to high-recurrence mutational targets.

Summary: The prevalence of disease-driven mass mortality events is increasing, with poorly resolved understanding of spatial variation in magnitude, timing, and triggers. A study on sea star wasting disease found that it affected the sunflower sea star more severely in the southern half of its range, leading to population declines and a lack of evidence for recovery. Temperature became more important in predicting the sea star distribution post-outbreak, indicating an interaction between disease severity and warmer waters in affecting outbreak severity.

Summary: The study found that the keystone species Pisaster ochraceus suffered from SSWS, but the likelihood of developing symptoms does not have a strong genetic basis. Although there are some genetic differences at the gene level, susceptibility to SSWS appears to be unrelated to genetic factors.

Summary: The incidence of emerging infectious diseases in wildlife populations, especially in marine environments, has been increasing. The management strategies used for terrestrial diseases may not be effective in marine habitats due to fundamental differences between the two systems. This article highlights the challenges and opportunities in wildlife disease management in marine environments, evaluates the application of common disease management strategies in marine and terrestrial systems, and recommends actions for better management of marine wildlife diseases.
