Summary: The study found that female eastern fence lizards treated with corticosterone (CORT) had lower metabolic rates 3-5 days post-parturition compared to control females, indicating that reducing metabolic rate may be a compensatory mechanism for maintaining energy balance under the influence of CORT. The research suggests that physiological responses to reproduction may be context-dependent and could minimize the costs of reproduction in situations where CORT is elevated, such as during periods of environmental stress.

Summary: Understanding the factors that regulate temporal changes in population size is crucial in ecology for maintaining species interactions, ecosystem stability, and biodiversity conservation. This study examined the population stability of 70 Amazonian floodplain fish species in relation to life-history traits and fishing pressure, finding significant relationships with certain life-history traits but not with fishing pressure. The findings stress the importance of life-history traits in controlling population size variation and can inform fisheries and conservation management strategies.

Summary: The integration of life-history, behavioural and physiological traits into a 'pace-of-life syndrome' is a powerful concept in understanding trait variation in nature. This study investigated the relationship between pace-of-life and thermal performance in damselfly larvae. The results showed a trade-off between a faster pace-of-life and higher thermal performance, suggesting that the energetically costly maintenance of a fast pace-of-life may contribute to the variation in pace-of-life within populations.

Summary: The study found that tolerance to contaminants influences levels of glucocorticoids (cort), with more tolerant populations showing lower baseline cort and higher fitness. Despite variations in cort across populations with different levels of tolerance, cort still represents a viable indicator of condition. Levels of cort were consistent regardless of whether amphibians were reared in contaminated or non-contaminated environments.

Summary: This study examines the effects of acute ultraviolet-B radiation (UVBR) exposure during early life stages on amphibian population dynamics. The results indicate that higher doses of UVBR exposure in tadpoles lead to faster metamorphosis, but result in smaller size and poorer condition in the resulting frogs. Additionally, the study provides empirical evidence of UVBR-induced telomere shortening, which may contribute to life-history trade-offs and post-metamorphic condition.

Summary: Life-history trade-offs are central to evolution, with genes like RLS1 shown to regulate photosynthesis to suppress immediate reproduction and ensure survival in nutrient-limiting environments. This study provides evidence for genetic factors influencing interactions between different traits within an organism.

Summary: In this study, the authors integrated long-term mark-recapture data, focal measurements of reproductive effort, a population matrix model, and inferences on life-history variation to reveal differences in demographic response to disease in a susceptible frog species. They found that a high disease prevalence population compensated through recruitment, leading to positive population growth, while the low disease prevalence population did not compensate and had decreasing population growth. The high prevalence population also had faster generation times and a positive relationship between disease prevalence and the proportion of juveniles, suggesting increased reproductive effort as a pathway for compensatory recruitment.

Summary: This study investigated how increasing salinization and nutritional algae influenced gut bacterial assembly, host physiology, and responses to ranavirus exposure in larval wood frogs. The results showed that elevating salinity and supplementing with algae increased larval growth and ranavirus loads. However, larvae given algae did not exhibit stress responses observed in larvae fed a basic diet, indicating a potentially adaptive stress response reversal. Algal supplementation also reduced gut bacterial diversity, with higher relative abundances of Firmicutes associated with host metabolism and endocrine function regulation.

Summary: This study evaluated the effects of corticosterone and synthetic glucocorticoids on muscle atrophy. The results showed that female mice were more sensitive to corticosterone treatment, while male mice had more pronounced responses to synthetic glucocorticoid treatment. Hormone signaling and androgens may play a role in sex differences in skeletal muscle response to glucocorticoids.

Summary: This study provides a general solution to calculate the cost function for any arbitrary, pairwise asymmetric signaling game at the evolutionary equilibrium. The results demonstrate that the cost of signaling at honest equilibrium has no effect on the stability of communication. Moreover, it shows that honest signals at the equilibrium can have any cost value, even negative, without requiring further constraints.

Summary: Posttraumatic stress disorder (PTSD) is a highly prevalent and disabling psychiatric condition. Glucocorticoids have emerged as a promising option for preventing the development of PTSD. Both clinical and preclinical studies have shown moderate evidence of the efficacy of glucocorticoid-based therapies in preventing PTSD.

Summary: Understanding the origin and evolution of life on Earth, as well as potentially on other planets in our solar system, is fundamental for humanity. Microbial communities have evolved over the longest period in Earth's history. Stromatolites, ancient lithified microbial mats, hold the key to understanding the evolution of microbial life on Earth and provide insights for planetary studies.

Summary: Anthropogenic environmental change, including climate change and urbanization, leads to warmer temperatures in terrestrial and aquatic habitats, affecting community assemblages and introducing invasive species. Changes in environment can have negative effects on anuran species, including reducing fitness and altering physiology and behavior. This study focuses on the response of Gulf Coast toads (Incilius nebulifer) to warmer water, reduced water levels, and invasive species, examining the role of corticosterone in modulating their response. The results show that tadpoles reared in warmer water and reduced water levels had elevated baseline corticosterone release rates, and toadlets exposed to multiple treatments showed an increased stress response. Additionally, exposure to the predatory red imported fire ant led to reduced predator avoidance and altered growth patterns in toadlets. Despite these challenges, Gulf Coast toads were able to persist by adjusting their physiology and behavior.

Summary: Climate change has diverse effects on populations, with variations in response across different populations and life stages. An experimental study on mole salamanders found that a slight increase in temperature during larval development had complex consequences, including density-dependent effects on growth and body mass, density-independent effects on fat storage, and no effects on survival and reproductive investment. Although warming reduced growth rates, size at maturity, and fat storage, it did not significantly impact survival and reproductive investment in the first year. However, smaller body size and lower fat reserves may limit overwintering survival and future reproduction.

Summary: Trade-offs between immune function and reproductive effort were investigated in female wolf spiders, revealing that reproductive effort did not impact immune function in spiders carrying young. Individual differences in resource acquisition may explain the lack of relationship between reproductive effort and immune response in spiders carrying young. Maintaining resources for immune responses across reproductive stages could increase fitness in female wolf spiders, reducing kin competition among spiderlings.
