Summary: Frost effects on savanna plant communities are similar to those from fire, altering community structure and species composition. However, the impacts of frost on the ground-layer community are not well-studied. This study in the Cerrado region of Brazil examined the effects of frost on ground-layer plant species along a tree cover gradient. Frost caused immediate dieback of perennial ground-layer, particularly in areas with low tree cover. While frost did not reduce species richness, it increased litter cover and decreased bare soil, potentially hindering crucial processes for plant population recovery.

Summary: Anthropogenic activities can cause changes in animal behavior. The population consequences of these behavioral changes are difficult to predict, especially for long-lived animals like beaked whales. This study reveals that exposure to military sonar may lead to population extinction or slight population increase, depending on various factors.

Summary: As human activities impact animal habitats, it becomes important to identify species at-risk from disturbance. Cetaceans show varying levels of responsiveness to anthropogenic noise, which cannot be fully explained by hearing sensitivity. This study found a high correlation between reduced foraging time during exposure to naval sonar and predatory killer whale sounds across four cetacean species, suggesting that ecoevolutionary factors that increase predation risk may also increase responsiveness to human-made noise.

Summary: Red tide blooms caused by Karenia brevis have significant ecological effects on the prey fish assemblage of common bottlenose dolphins in Sarasota Bay, Florida. The impacts vary based on bloom intensity, season, and frequency, with distinct short-term shifts in prey structure during blooms. High K. brevis density is associated with changes in prey abundance and diversity, with recovery to pre-bloom levels typically occurring within one year.

Summary: Studying the impact of earthquake-induced disturbances on lake microbial communities using sediment DNA analysis revealed significant differences in composition and function, indicating a lack of resilience to large-scale natural pulse disturbances. This research highlights the destabilizing effect that large pulse disturbances, such as increased sediment inputs, can have on lake ecosystem processes.

Summary: Evidence suggests that organisms can adapt their interactions with others in response to declining population sizes, with the proposed 'second-degree rewiring' rule serving as a biologically plausible regulatory mechanism to maintain network stability and promote assortativity. Empirical data confirms the effectiveness of this regulatory mechanism in maintaining network properties in shrinking populations.

Summary: Quantifying the geographic range of a species is crucial for effective conservation management, as seen in the case of the Western Tragopan in Pakistan. The developed model predicted potential breeding habitat, with only 2.6% being highly suitable, indicating the urgent need for protection measures to prevent further habitat deterioration for this globally threatened species.

Summary: This study proposes a satellite-based approach to assess ecosystem resilience to wildfires based on post-fire trajectories of four key functional dimensions of ecosystems related to carbon, water, and energy exchanges. The study used MODIS data for 2000-2018 to analyze trajectories after the 2005 wildfires in NW Iberian Peninsula. The approach successfully depicted key features of post-fire processes of ecosystem functioning at different timeframes and has promising implications for post-fire ecosystem management.

Summary: The study compared the plasma metabolomes of bottlenose dolphins in post-absorptive and 24-hour-fasted states, revealing changes in lipid metabolism, protein catabolism, and synthesis consistent with a diabetic-like fasting state. Pathway analysis predicted increased cytokines and apoptosis in response to fasting. Furthermore, a dynamic network marker indicative of a physiological shift toward a negative energy state was identified, with potential applications for assessing energy balance in wild dolphins at risk.

Summary: Caloric restriction affects the metabolome in a tissue-specific manner, with only a small number of common metabolic features responding in the same way across all tissues. The top modulated pathways were related to biosynthesis and degradation processes, suggesting each tissue has its own unique way of coping with reduced energy intake, supporting the clean cupboards hypothesis over the disposable soma interpretation.

Summary: This study investigated the effects of environmental factors on the average daily milk yield and day-to-day variation in milk yield of barn-housed Scottish dairy cows. The results showed that multiparous cows had higher initial milk yield and total lactation milk yield, while primiparous cows had the greatest incline slope and persistency. The temperature had minimal effect on milk yield, but as the temperature increased, the variation in milk yield decreased for both primiparous and multiparous cows.

Summary: Dairy cows are capable of forming stable social groups and long-lasting relationships with conspecifics. This study found consistent social associations at the AMS, which may impact milk yield and composition. Multiparous cows exhibited stronger social associations compared to primiparous cows, which influenced milk fat and protein percentages.

Summary: Cumulative exposure to anthropogenic stressors can impact the health and reproduction of coastal cetaceans. The concept of health for cetaceans in an ecological context is not well understood. Using a health-monitoring program, this study found that individuals in poor health showed changes in metabolic pathways. Further research is needed to understand the interplay between health and energy metabolism in cetaceans.

Summary: One of the main threats to wild primates is habitat alteration, fragmentation, and destruction. A study on capuchin monkeys in Paraguay found that they exhibit diet plasticity and can adapt to degraded forest conditions by opportunistically taking advantage of crop plants. This ability to adjust their diet in different habitat fragments highlights the importance of small islands of Paraguayan Atlantic Forest for their persistence.

Summary: Human activities at sea are becoming more complex, requiring adaptable management interventions to mitigate their cumulative effects on biodiversity conservation. Coastal cetaceans, particularly harbour porpoises, are threatened by bycatch and the indirect effects of repeated exposure to disturbances such as acoustic disturbances. The prevalence of pingers, used to mitigate bycatch, can affect both bycatch rate and the population consequences of noise disturbance. Understanding the physiological effects on reproductive decisions and behavioural responses to noise is crucial for evaluating the cumulative impacts of bycatch and its mitigations.

The COVID-19 pandemic has highlighted the importance of nature exposure for wellbeing and our study shows that people sought greenspace during mobility restrictions. However, access to greenspace varied depending on neighborhood deprivation, and the preference for greenspace intensified throughout the waves of lockdown.

Summary: Calorie restriction extends life span by modulating aging-related mechanisms. Metabolic pathways such as glycolysis/gluconeogenesis and fatty acid degradation are significantly stimulated, while main signaling pathways and pathways in cancer are not significantly affected. Moreover, the metabolism of xenobiotics is altered by calorie restriction.

Summary: Reliable information on the spatial and temporal distribution of mobile species is essential for effective conservation management in the face of human impacts. Utilizing a maximum entropy model, this study found differences in distribution patterns for odontocete species in Maui, Hawai'i, particularly when calves were present or in different seasons. The overlap between dolphin schools with calves and vessel traffic in the region poses a risk for collision and chronic stress, indicating a need for specific regulations to mitigate anthropogenic influences and conserve endangered populations.
