Summary: Geotechnical field measurements in energetic beach environments are still rare, but a study in Germany's Sylt Island revealed trends of increasing grain size and friction angles in the subaerial and intertidal zones, as well as significant sediment resistance in the swash zone and upper subtidal zone. Pore pressure recordings showed consistent trends with tidal water elevations, with a decoupling of surface water effects and groundwater during low tide, suggesting possible gas content and negative pore pressures in the vadose zone. The 1DV pore pressure model successfully simulated observed pressures at all sediment depths, indicating no liquefaction events but a reduction of effective weight affecting sediment dynamics.

Summary: Studies comparing genetic diversity distribution patterns in marine populations can help reveal connectivity patterns, while considering evolutionary history is important when studying population connectivity in sandy beach populations. Different species of sandy beach macrofauna showed varying levels of genetic homogeneity, with potential impact from factors like dispersal strategies and historical processes.

Summary: Artificial light at night (ALAN) is a global driver of change, but its effects on sandy beach communities and different life stages of species are still unclear. A field experiment in Chile revealed that ALAN significantly altered the community structure, with species showing different responses at different life stages. These findings highlight the potential long-term impacts of ALAN on sandy beach ecosystems.

Summary: This paper proposes a new approach to describe coastal morphodynamics using optimization theory, assuming that a sandy beach profile evolves to minimize a wave-related function based on the driving force behind the coastal morphodynamic processes considered. The derived numerical model uses a gradient descent method and can account for physical constraints such as sand conservation. The ability of the model to simulate cross-shore beach morphodynamics is demonstrated and compared with experimental data and the results from another coastal morphodynamic software.

Summary: Ocypodid crabs on the Amazon coast show marked variations in burrow abundance and distribution due to rainfall and depth, with growth parameters similar to subtropical areas rather than global ecological trends. The large beach width and local climate are key factors influencing the population trends, suggesting that moisture plays a significant role in habitat utilization by these individuals.

Summary: This study selected two temperate sandy beaches located on the coast of different seas with different hydrological states to investigate the variations and drivers of the taxonomic structure and functional traits of free-living marine nematodes. The species composition and functional traits of nematodes were not completely the same in the two locations, with a relatively restricted range of functional traits in fine sands and increased microhabitat heterogeneity supporting species with more diverse functional traits in coarse sands. Chl-a was identified as the most prominent variable significantly related to nematode species composition and functional traits at XB sites, while nematode data at GB sites were closely related to temperature or temperature-related environmental factors such as DO and salinity.

Summary: Atlantic herring has a complex population structure and displays various reproductive strategies. Mixing between spring and autumn spawning herring occurs on the spawning ground, with differences in reproductive traits observed. The high variability in reproductive investment within spring spawners suggests the co-occurrence of groups with different behaviors.

Summary: A study conducted at Cassino Beach in South Brazil found that urban sites had higher amounts of litter, mostly composed of plastic, with beach use-related litter being more common. The highest litter concentration was found during the summer season when beach use increases. Undefined and/or beach use-related sources were dominant in all sites and seasons.

Summary: This study investigates the life cycle, population dynamics, and reproductive biology of the key species Atlantorchestoidea brasiliensis on a Southwestern Atlantic Coast sandy beach. The results show that this species exhibits continuous reproduction and multiple cohorts, and its biological traits are similar to those found for amphipods in South America but differ from those in North Atlantic. Evaluating life history-based biological traits is crucial for management decisions.

Summary: A field study of aeolian transport over a wet bed in the intertidal zone was conducted, showing that transport over wet beds is fundamentally different from that over dry beds. More research is needed to understand the mechanisms driving deviations in flux profiles over wet beds in field environments.

Summary: It is well-known that the coastal zone attracts human populations like no other. Coastal processes and sediment availability play a major role in shaping sandy beaches. This study examines the morphological changes of a sandy beach in Durban, South Africa over a period of nine years. The results show a net loss in volume and area of the beach, with significant differences in response between different parts of the beach. The wave climate and sediment availability are key factors influencing the beach's response. Artificial nourishment may be required in the future to maintain the sandy beach.

Summary: This study investigates the effects of crowding on demographic processes, fecundity, and social structure in European free-tailed bats. The results show that crowding after habitat loss can disrupt population processes, reducing genetic relatedness and apparent survival, but not fecundity.

Summary: Understanding age-specific demography in wild African elephants revealed that survival plays a more significant role in population growth than fecundity, with both factors decreasing in influence with age. Young adults demonstrated the highest elasticity, while the oldest females had the lowest, despite their high fecundity. Human impacts and population size were found to be the strongest correlates of survival across sexes and ages.

Summary: Beach erosion is a complex process influenced by multiple factors at different spatial scales. This study reveals the combined influence of regional and local factors on erosion rates, with the energy dissipation gradient emerging as a critical factor. Climate change also has a tangible impact on beach erosion patterns. Human activities play a significant role in explaining erosion trends. Integrating localized measurements with broader satellite observations is essential for a comprehensive understanding of coastal evolution drivers.

Summary: Sustainable agricultural practices are increasingly important for global and national environmental policies and economy. This study compared the sustainability of grape production under integrated and organic management using multiple indicators. The results showed that organic management was more beneficial for most environmental aspects of the agroecosystem compared to integrated management, without affecting grape yield.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
