Summary: Brooding is a reproductive strategy in bivalves that protects larvae from predators and adverse conditions, but recent studies on brooding oysters have shown that larvae in the pallial cavity may be negatively affected by chemical conditions. This study examined how conditions in the pallial cavities of non-brooding O. chilensis females are influenced by environmental conditions and respiration.

Summary: The discovery of a new species of dwarf males of Ostrea jibananandai sp. nov. attached to large females in a facultative monogamous relationship suggests an increase in successful fertilization. This unique phenomenon, named as facultative monogamy, has only been found in these three species of oysters.

Summary: Juvenile oysters from different populations in Chile showed reversible reduction in feeding rates when exposed to paralytic shellfish toxins. Oysters from the estuary accumulated toxins more rapidly but had lower detoxification capacity compared to bay population. Survival rate was significantly higher in estuary oysters.

Summary: Two congeneric species, the Northern lapwing and the Red-wattled lapwing, which inhabit different climate zones, exhibit differences in brooding patterns and efficiency. Higher brooding rates do not have a negative effect on the growth rate of the chicks.

Summary: This study investigates the components, concentrations, distribution characteristics, and sources of low-molecular-weight organic acids (LMWOAs) in the Changjiang Estuary and its adjacent sea area. The results show that terrigenous inputs, especially the Changjiang runoff, are the dominant sources of LMWOAs. The consistency between hypoxia areas, high concentration areas of LMWOAs, and low pH value areas suggests that annual hypoxia could cause long-term seawater acidification by producing LMWOAs.

Summary: The nutrient and carbon dynamics within river-estuary-coastal water systems were analyzed to understand the flux of matter from the terrestrial environment to the ocean. The study revealed that the distribution and variations of nutrients and carbon varied significantly in different water environments, influenced by the travel time of water and nutrient fluxes, thereby affecting the functionality and stability of the aquatic ecosystems.

Summary: The study investigated the gametogenic cycle and spatial variation of Foveaux Strait Ostrea chilensis. The findings suggest that reduced brooding rates may be due to poor condition of oysters and decreased male densities.

Summary: The study conducted by the United States Environmental Protection Agency's National Estuary Program (NEP) in collaboration with partners in seven estuaries along the East Coast, West Coast, and the Gulf of Mexico demonstrated that temperature and pCO(2) covaried across all water bodies, with average pCO(2) being lower in cooler, winter months and higher in warmer, summer months. The research also found that both thermal and non-thermal influences are important drivers of pCO(2) in Tampa Bay and Mission-Aransas Estuary, while non-thermal processes, notably coastal upwelling, are responsible for pCO(2) values in West Coast water bodies. The study highlights the importance of high-quality carbonate chemistry observations in estuarine environments using autonomous sensors originally designed for open-ocean settings.

Summary: This study assessed the performance of Durafet-based sensors in estuarine waters and found dynamic errors in the temperature and salinity responses of the internal and external reference electrodes. The errors were primarily driven by tidal mixing and were corrected using a dynamic sensor response correction method. The results showed that salinity change was the strongest limiting factor for the reference electrode response.

Summary: This study investigates the effects of heat waves on telomere dynamics and parental brooding behavior in zebra finch nestlings. The results suggest that the impact of heat waves on telomere dynamics varies depending on the age and thermoregulatory stage of the offspring, as well as parental brooding behavior.

Summary: Pterosaurs displayed a wide range of body sizes, with some reaching sizes comparable to small airplanes. The growth strategies that allowed these giant pterosaurs to attain their large adult sizes are largely unknown. This study examines the wing development and performance of different pterosaur species, revealing differences in growth patterns and suggesting a shift towards enhanced parental care as a possible factor in allowing the evolution of large body sizes.

Summary: Parental care has been gained and lost evolutionarily multiple times. The loss of parental care is influenced by low egg and adult death rates, quick egg maturation, and high level of care provided. Evolutionary hysteresis makes it challenging to lose parental care, particularly when eggs develop slowly.

Summary: An unprecedented investigation was conducted to study the seasonal variability of carbonate system parameters in the Patos Lagoon Estuary. The study found that the estuary had alkaline conditions throughout the year, with surface waters generally being supersaturated with calcium carbonate. However, during winter and spring, undersaturation conditions were observed. The study also revealed that the dominant processes influencing changes in the carbonate system were salt dilution and concentration. Nonthermal effects had a greater impact on seasonal changes in pCO(2) than thermal effects.

Summary: Parental care behaviors in notothenioid fishes are associated with the diversification into different habitats in the subzero waters around Antarctica and the sub-Antarctic environments. These behaviors include courtship, mate choice, nest construction, and egg guarding until hatching. Antarctic cryonotothenioids display larger egg size and reduced fecundity, indicating a trend towards parental care behaviors.

Summary: Encapsulated development with extraembryonic yolk can lead to competition for nutrients within egg capsules. Research found that more crowded egg capsules resulted in lower survival rates for juveniles, while individuals hatching from less crowded capsules showed better performance initially. However, over time, the largest surviving juveniles became the best performers, regardless of initial embryo density within the capsules.

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 evaluates the effects of bleaching on the oocytes of the Mussismilia harttii coral and investigates the strategies employed by these cells to maintain antioxidant balance and cellular homeostasis. The research finds that bleached coral oocytes experience lipid damage, but are still able to maintain their quality and potentially elongate their lifespan and fertilization capability. This response may be linked to an intensification of heterotrophy in bleached corals.
