Summary: The Maastrichtian-Danian (K/P) transgression in northern-central extra-Andean Patagonia covered both Mesozoic sedimentary basins and the Northpatagonian Massif, resulting in a regional unconformity/nonconformity between the pre-Cretaceous base and the K/P marine transgressive record. The transgressive stratigraphic record over the basement is mainly composed of isolated carbonate bioclastic deposits and is interpreted as rocky shore associations. The colonization of engineer ecosystems organisms and the presence of a short-lived, transgressive, cool-water carbonate factory enhanced coastal biodiversity.

Summary: More than half of the world's coastlines are rocky, but the dynamics of rip currents on these topographically complex shores have not been studied. Field experiments on a typical rocky shore have revealed that narrow-banded swells generate low-frequency waves that lead to the formation of set-up, run-up, and mass flux on the shore. Rip currents on rocky shores exhibit differences in scale and forcing mechanism compared to sandy beaches.

Summary: Individual traits and population parameters can serve as proxies for processes happening at different scales, enhancing our understanding of species responses to environmental changes. In this study, the effects of intertidal height and shore orientation on mussels were examined to understand individual and population dynamics. The results show significant impacts of these factors on individual traits and population parameters, with spatial variability influencing performance and processes at the population level. The findings suggest the importance of considering heterogeneous within-site conditions in modeling metapopulations with spatially explicit processes.

Summary: Climate change not only affects the average values of environmental parameters, but also changes the pattern of disturbances. Extreme events play a key role in structuring biological communities, and their effects can be strengthened when combined with other pressures. Research indicates that extreme events have a greater impact on species assemblages in areas with higher anthropogenic pressure, and the recovery time is longer. The intertidal zone is more resistant and capable of recovering from extreme events compared to the subtidal zone.

Summary: Groundwater discharge plays a significant role in coastal aquatic ecosystems, but its patterns, importance, and effects on rocky shores communities are largely unknown. This study assessed the importance of groundwater discharge in intertidal ecosystems using benthic macroinvertebrate composition and abundance as indicators. The results showed that groundwater discharge significantly affected the abundance of biological communities across all shores, but did not impact biodiversity patterns. Certain algae, snails, and lichens could be used as bioindicators for shifts in groundwater discharge patterns.

Summary: The impacts of upgrading treated sewage discharge on a rocky shore in southern Australia were studied, revealing an increase in fucoid abundance near the outfall and within the nutrient plume, but no significant changes in distant reefs. Changes in dissolved inorganic nitrogen (DIN) concentration around 2.0-2.5 μM may trigger large-scale ecological changes associated with the loss of a dominant intertidal species.

Summary: This study examines the impacts of ocean acidification on tidepool communities, focusing on the interactions within a three-level food web. The results show that experimental declines in seawater pH suppress the anti-predator behavior of snails, leading to a diminished top-down control of predators on basal resources. These findings suggest that ocean acidification may alter cascading effects within food webs.

Summary: Endolithic cyanobacteria commonly erode mussel shells, affecting mussel physiological conditions like growth and reproduction. Parasitized mussels have increased basal metabolic rates and decreased scope for growth without compensatory increases in feeding or reduced ammonia excretion. Infested mussels expend more energy in repairing the organic component of the shell's inner nacreous layer, leading to decreased scope for growth.

Summary: This study compared the genetic structure of two co-distributed intertidal red algae along the South African coastline, finding that Gelidium pristoides has two evolutionary lineages while Hypnea spicifera is genetically homogeneous throughout its range. Genetic breaks in G. pristoides are associated with contemporary coastal dunefields, possibly reflecting the influence of older dispersal barriers and maintenance of genetic structure by the formation of contemporary coastal dunefields.

Summary: The brachyuran crabs Carcinus maenas and Hemigrapsus sanguineus are successful invaders along coastal areas. They compete for food, with C. maenas better suited for animal food and H. sanguineus better suited for algae food. H. sanguineus can increase its utilization of algae food when animal food is scarce or competition with C. maenas is intense.

Summary: A two-year experiment was conducted to investigate the impact of Pollicipes pollicipes harvest on intertidal community structure and ecological diversity. The study found that intensive exploitation resulted in a decrease in P. pollicipes and Mytilus spp. coverage, while Chthamalus spp. and Corallina spp. increased. The recovery of P. pollicipes aggregations was slow and variable, but their coverage increased under non-extracted conditions.

Summary: This study analyzes the early Pliocene palaeoenvironmental context of the Almeria-Nijar Basin in the Mediterranean, with a special focus on conditions after the Messinian Salinity Crisis (MSC). The research suggests the establishment of well-ventilated marine conditions in the Mediterranean after the MSC, potentially due to a global sea-level drop. Changes in terrestrial organic matter and sediment inputs during the early Pliocene may be linked to variations in river discharge.

Summary: Many temperate ecosystems today are the result of colonization of barren substrates as a result of deglaciation during the Holocene. Direct evidence of post-glacial colonization is rare but can be found in buried subfossil burrows in coastal dunes. Tiger beetles are early successional tracemaking colonists known from open habitats worldwide. The subfossil burrows found in Polish coastal dunes may represent colonization by tiger beetles and other early successional species dating back millennia.

Summary: This study provides a comprehensive overview of the dynamics of the upper branch of the Atlantic Meridional Overturning Circulation (AMOC) in the mid-latitudes of the Northeast Atlantic. It focuses on the European Slope Current (ESC) and its glacial equivalent known as the Glacial Eastern Boundary Current (GEBC). The study reveals significant changes in flow strength and ventilation during the glacial and deglaciation periods, as well as a gradual weakening of the slope current during the Holocene.

Summary: The cause of ice-age cycles is still not fully understood, and studying the timing and magnitude of mountain glaciations can provide valuable insights. This study presents new dating results from the Niqingqu Valley in the Tibetan Plateau, showing multiple glacial activities prior to the Penultimate Glacial Maximum. The findings suggest that low atmospheric CO2 content and reduced summer solar insolation/high summer-monsoon precipitation played a role in these glacial fluctuations.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
