Summary: Ensuring genetic integrity is crucial in conservation-oriented captive breeding programs, especially for endangered species like freshwater pearl mussels. A study comparing the genetic makeup of captive-bred mussels from different facilities with their original source populations found close resemblance but also signs of inbreeding. Long-term breeding over multiple years can minimize erosion of genetic diversity, while effective breeding strategies and collaboration networks can enhance resilience and effectiveness in conservation efforts.

Summary: The demographics of young-of-year Pondmussels and Giant Floaters in ponds showed variations in size, sex ratios, and gravidity among ponds due to differences in environmental conditions or demographic stochasticity. Size and fecundity were not related to male density, and acquired immunity did not affect YOY performance in both species. The rapid growth, early maturity, efficient fertilization, and high fecundity of YOY contradict traditional views of mussel life history, but may enable them to colonize disturbed, unstable habitats quickly.

Summary: Understanding the drivers behind size variation is important, as body size often predicts energetic requirements and fecundity. Neo-Bergmann's rule states that larger individuals are found at higher latitudes, and this size variation is attributable to temperature gradients.

Summary: Anthropogenic freshwater habitats offer potential for long-term conservation of freshwater mussels, but may also act as ecological traps. These habitats are not a cure-all for conservation problems, and more research is needed to understand the trade-offs between human use and conservation within them.

Summary: Bivalve aquaculture in nearshore sites has expanded worldwide. Mussel farming productivity is commonly assumed to depend on survival and growth performance, which can be highly variable among spat stocks originating from different sites, even at a microgeographical scale. Offshore conditions clearly enhanced overall growth performance independently of stock origin, as shown by the higher condition indexes, higher energy lipids (triacylglycerol), and generally higher glycogen content in mussels at the end of the production cycle. The observed survival (+23%) and growth (+27%) trends support the hypothesis that offshore cultivation represents a valuable strategy for mussel aquaculture development.

Summary: Biogeochemical ecology research typically focuses on C, N, and P elements, with less attention to broader elemental diversity in animal ecology. This study on freshwater mussels demonstrates that interspecific trait variation may influence shell elemental composition, offering new insights into elemental allocation associated with biological traits.

Summary: This study aims to assess the ingestion of microplastics by aquatic organisms in freshwater ecosystems. The findings highlight the influence of body-size and pollution on microplastic ingestion, with fibers being the most prevalent microplastic type across trophic levels. Only fish exhibited fragments within their gastrointestinal tract. There is a substantial correlation between microplastic abundance and mussel size and weight, and a positive link between microplastic count and turbidity, impacting mussel ingestion capacity. Water quality parameters did not show a distinct pattern for fish concerning ingested microplastics.

Summary: This study reveals the impact of hydroelectric dams on the Wolastoq | Saint John River in New Brunswick, Canada, which restricts the habitat of fish and their parasitic mussel larvae. However, despite this restriction, the number of affected fish species has significantly increased. The research provides critical baseline data on symbiotic interactions in this river ecosystem and highlights the complexity of current management plans for river regulation and fish passage.

Summary: The origin of the fauna in Beringia is a biogeographical puzzle. Beringiana mussels offer a model to study the paleobiogeography of Beringia and species exchanges. Limited data on their distribution, morphology, genetics, and taxonomy exist. This study analyzed their genetic sequences and shell morphology, finding variation within populations and identifying all individuals as B. beringiana. The study also evaluated possible dispersal pathways, including through intercontinental migration on fish.

Summary: The sensitivity of forests to near-term warming and precipitation shifts remains uncertain. A 5-year open-air experiment in the southern boreal forest showed that different North American tree species had divergent responses to climate alteration. Warming and reduced rainfall increased the mortality of all species, especially boreal conifers. Different species had different growth responses to warming, with some experiencing enhanced growth while others had severe growth reductions. Treatment-induced changes in photosynthesis and growth explained the changes in survival. Species that experienced conditions warmer or drier than their range margins had the most adverse impacts on growth and survival. Climate change is likely to cause regeneration failure of currently dominant southern boreal species, leading to tree regeneration shortfalls. This will have potential adverse impacts on the health, diversity, and ecosystem services of regional forests.

Summary: This study evaluated the effect of temperature on the embryonic development, growth, and larval survival of the yellow clam Amarilladesma mactroides. The results showed that the embryos of this species are tolerant of temperature variation and the larvae demonstrate better growth and survival at lower temperatures (18℃ and 20℃).

Summary: A pioneering quantitative study conducted in 1966 on freshwater mussel populations in the River Thames, UK, has been extensively cited as evidence of the significant contribution of mussels to global river ecosystems. A recent resurvey of the same site revealed large declines in mussel population density, changes in species composition, growth patterns, and productivity. The study also highlighted the invasion of nonnative mussel species and the detrimental impact on ecosystem services in the River Thames.

Summary: The study investigated the toxic effects of Chlorpyrifos 20 EC, an extensively used agro-pesticide in Bangladesh, on the freshwater mussel Lamellidens marginalis. The mussel was exposed to varying concentrations of Chlorpyrifos 20 EC for 35 days, resulting in detrimental effects on growth, hemocyte counts, and histopathology. The study found that higher concentrations of Chlorpyrifos 20 EC led to decreased growth rates, abnormal hemocyte counts, and severe pathological signs in gill, muscle, and ovary tissues.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
