Summary: Experimental results show that human sperm exhibit reduced motility and other kinematic parameters under starvation conditions, while treatment with energy recovery restores hyperactivated motility, rapidly increasing ATP and cAMP levels. This suggests that modulating sperm energy levels through such treatment may positively impact human sperm fertilizing ability in vitro.

Summary: Recreational use of parks and protected areas can have significant impacts on resources, but it is difficult to mitigate these impacts. In this study, we used a novel tool called step selection function (SSF) analysis to identify areas with high probabilities of recreational disturbance. By analyzing the campsite selection of backcountry kayakers in Glacier Bay National Park and Preserve, we found that campers tend to select sites with bare, flat ground, close to freshwater sources, and with good views of glaciers and scenery. Our results provide predictive maps to locate areas with high potential for camping based on site characteristics, which can be used for prioritizing monitoring, restoration efforts, and management actions.

Summary: In this study, we used spatiotemporal analysis to identify the areas in the Russian Federation where an increased density of wild boar population is associated with a higher concentration of African swine fever (ASF) cases. We found areas where the wild boar population density has been continuously rising in recent years, which may be considered high-risk areas requiring enhanced surveillance and population control measures.

Summary: A review of literature and analysis of over 19,000 terrestrial protected areas worldwide found that the differences between strictly protected areas and areas where multiple human uses are permitted are often small and not statistically significant. While the effectiveness of protected areas varies globally, factors beyond their assigned IUCN category are likely influencing this pattern.

Summary: African swine fever (ASF) is a highly contagious disease that has spread to more than 30 countries in Europe and Asia since 2007. The recent outbreak in mainland Italy has had a significant impact on the population of wild boar, leading to a cascade effect in the ecosystem. Camera traps have been shown to be effective in monitoring ASF infection, providing valuable data on movement parameters, population density, recruitment, and human compliance with restrictions. These parameters play a crucial role in optimizing ASF control efforts.

Summary: This study compared the receptor architecture of the primary visual and early extrastriate cortex in macaque and human brains, identifying distinct areas with different receptor patterns. While the 1st principal component separated macaque and human early visual areas, the 2nd principal component revealed area-specific differences within each species correlated with hierarchical processing levels. Subdivisions of V2 and V3 clustered together in both species and were segregated from subdivisions of V1 and V4v, providing valuable insights into how differences in underlying microstructure impact functional processing in the primate brain.

Summary: Effective conservation requires understanding the processes that determine population outcomes. The density of leopards is primarily limited by human impacts, but habitat suitability and management conditions also matter. Protected areas only play a role in large felid conservation when there is effective management of human-wildlife interface and protection from anthropogenic impacts.

Summary: Monitoring human activities in border areas is challenging due to complex geographical environment and diverse population. A human activity intensity index (HAI) was proposed based on land cover, population density, and satellite-based nighttime light for a long-term macroscopic study. The study found that human activity in China's border areas is higher than in neighboring countries, with significant increase in land use intensity since 1992. India had the highest HAI with the fastest growth among China's neighbors. Four regional evolution patterns and three spatial evolution patterns were identified. The changes in HAI not only affect the eco-environment, but also impact geopolitics and geoeconomics. The HAI can be used for decision-making and cooperation in areas such as ecological protection, border security, and border trade between China and neighboring countries.

Summary: This research surveyed 103 marine turtle conservation researchers and practitioners globally to understand how conservation efforts can be better allocated to curb illegal harvest, use and trade. The findings show that despite some progress, illegal activities remain significant threats to marine turtle populations. The challenges in addressing illegal activities are related to fisheries management, enforcement, and legislation. The recommended priority actions include law enforcement, enhancing environmental literacy and stakeholder participation, and improving local conservation leadership and management. Further empirical research is needed to validate these findings and understand the influence of individual experience and perspectives in conservation.

Summary: Shorebirds and seabirds are used as bioindicators of environmental contamination in marine ecosystems. A study in the Bijagós Archipelago found low exposure of these birds to toxic elements, except for mercury. There were differences in trace element concentrations between trophic guilds, with different elements higher in pelagic fish consumers (seabirds) and benthic invertebrate consumers (shorebirds). Although there is currently no toxicological risk to these bird populations, further monitoring of high mercury burdens is recommended.

Summary: Animals often face trade-offs between food acquisition and predation/disturbance avoidance. However, the impact of modulating factors such as thermal risk and foraging opportunities on this trade-off has been largely disregarded. In this study, we investigated the influence of temporal and environmental gradients on the flight initiation distance (FID) and escape mode in shorebirds, and found that heat-stressed shorebirds take greater risks and adjust risk-taking behavior according to tidal and seasonal cycles.

Summary: This study provides the first description of the phylogeographic patterns and historical demography of Bulwer's petrel, as well as insights into the drivers of species diversification in the marine environment. Three highly differentiated groups were identified, including the Western Pacific, Central Pacific, and Atlantic populations. The Isthmus of Panama restricts gene flow between oceans, but the deepest phylogeographic break occurs within the Pacific Ocean, where oceanographic barriers play a key role in driving and maintaining the remarkable structure found in this highly mobile seabird.
