Summary: In this study, the foraging efficiency of long-billed hermit hummingbirds was examined in relation to their exploration, risk avoidance, and arousal behavioral traits. It was found that foraging efficiency was lower in high-risk conditions, but the effects of behavioral traits varied depending on the environmental conditions. More explorative individuals had higher foraging efficiency in low-risk conditions, while the opposite was true in high-risk conditions. Regardless of the conditions, foraging efficiency increased with bird arousal and decreased with risk avoidance. These findings highlight the importance of considering additional behavioral dimensions to better understand individual foraging strategies.

Summary: Despite the sensitivity of amphibians to contamination, fish toxicity data may not accurately predict the effects on all aquatic life stages of amphibians. More research on lethal toxicity for amphibians is needed to reduce uncertainties. This review proposes a test based on spatial avoidance as a more humane alternative to lethal tests for assessing chemical toxicity in amphibians.

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: Exposure to crude oil has been shown to lead to reduced sociability and poor habitat selection in fish, corresponding with increased predation risk. The study suggests that behavioral impairment may be more sensitive than cardiorespiratory injury and could be a more significant driver of ecological risk in marine species following oil exposure.

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: The study found that tadpoles of the Clinotarsus curtipes species do not show behavioral responses to the chemical signals of a predator insect, but they exhibit anti-predator behavioral responses to the water-borne cues released from the predator's excreta after consuming either conspecific or heterogeneric prey tadpoles.

Summary: Birds can adjust their parental activity based on the perceived risk of nest predation. This study investigated the potential sexual differences in the risk assumed by blue tit parents when taking care of nestlings in response to perceived predation risk. The results showed that both females and males did not differ in the risk assumed in response to perceived predation risk. However, females reduced their time devoted to nest sanitation activities when predator chemical cues were detected inside the nest-box, indicating a potential anti-predatory strategy. These findings suggest that birds can detect and respond to olfactory cues of predation risk inside the nest cavity, and this behavioral response is not dependent on sex.

Summary: The study finds that household investments in smog avoidance and medical expenditures do not have substitution effects, and perceptions of pollution intensity, pollution protection knowledge, and future health preferences promote smog avoidance investment and medical expenditures. Additionally, air pollution avoidance investment greatly increases the likelihood that urban residents rate their health as good.

Summary: High scores on Harm Avoidance (HA) on Cloniger's Temperament and Character Inventory (TCI) have been identified as a risk factor for depression. Group cognitive-behavioral therapy (GCBT) has been found effective in preventing depression and improving depressive symptoms among university students with high HA. This study aimed to evaluate the effectiveness of GCBT in reducing HA and preventing depression in this population.

Summary: The study reveals that long-term exposure to different food levels and light conditions significantly influences the antipredator behavior of fire salamander larvae. Individuals exposed to low food levels and 8-hour light conditions were more likely to take risks in response to predation stimuli. This highlights the interactive effects of environmental factors on shaping antipredator responses and emphasizes the complexity of behavioral adaptation to changing environments.

Summary: The study found sharp but leaky transitions between parapatric populations in different geographical locations, indicating gene flow can occur despite selection pressure. Bombina populations exhibit permeability to gene flow, but their species integrity remains intact due to their wide geographical ranges and ecological differentiation.

Summary: Observations on the ontogeny and diversity of salamanders have shed light on the evolution of animal forms, with advances in understanding developmental mechanisms, phylogenetic relationships, and the impact of ecology on development. Molecular phylogenetic analyses support the majority of branches in the Salamander Tree of Life, and the ancestral reconstructions reveal repeated transitions between life cycle modes and ecologies. The colonization of diverse habitats has led to phenotypic diversification and convergence in some cases, while unrelated lineages may follow different developmental pathways to arrive at convergent phenotypes.

Summary: Contemporary climate change has varying effects on population dynamics depending on landscape structure. This study investigates the impacts of warm climates on lizard traits and population dynamics in habitats with different connectivity. The results show that warm climates have different effects on lizard populations depending on the connectivity among thermal habitats, and landscape fragmentation can drastically alter population responses to climate change.

Summary: The introduction of alien predators, such as mosquitofish, poses a global threat to amphibians. However, there is a lack of in situ studies on the trophic interactions between these predators and native amphibians. This study investigates the trophic interactions between Eastern mosquitofish and palmate newts, revealing potential impacts on larvae and eggs but limited overlap with adult newts in terms of trophic niches.

Summary: Two ecological studies on amphibians show that the skin microbiota of hosts plays a key role in resisting pathogens, and the dysbiosis of these microbiota can be caused by various factors including population translocation. By conducting an experiment of yellow-spotted salamander larvae translocations, researchers found that the composition, diversity, and structure of the skin microbiota underwent significant changes over a 15-day period, but were not significantly affected by the translocation event.

Summary: Climate change and invasive species are major factors causing biodiversity loss, and their interaction can further exacerbate this problem. This study focused on the marsh frog, an invasive species in Western Europe, and found that it has a broad thermal tolerance and prefers higher temperatures than its current environment. These traits enable the marsh frog to potentially benefit from a warmer climate, expand its range, and increase its invasion success.

Summary: Introduction of fish into fishless high-altitude lakes negatively impacts biodiversity. Eradicating alien fish through intensive fishing is expensive and challenging in productive lakes. The draining of Lake Sulzkarsee in Austria, combined with sediment treatment, was partially successful in eliminating fish, but the introduced minnows survived and reproduced. The recovery of indicator species was short-lived when minnows returned after the failed eradication attempt. Purse seines were found to be the most efficient gear for catching minnows. These findings highlight the difficulty of draining deep mountain lakes and the need for sediment treatment to ensure complete fish removal.

Summary: Freshwater predators, specifically post-metamorphic anurans, exhibit a diverse trophic spectrum by foraging in both terrestrial and aquatic habitats. This study focused on the foraging habits of introduced marsh frogs and found that they have generalist and opportunistic feeding strategies. The study also highlighted the potential ecological control that these frogs have on pond communities, exerting predation pressure on a wide range of organisms. The results suggest that considering the functional traits and microhabitats of consumed prey can aid in understanding the specific components of pond communities targeted by anuran predation. Furthermore, the study raises concerns about the predatory role of introduced marsh frogs in the context of biological invasions.
