AI Article Synopsis
- Biological invasions, particularly by an invasive mussel, are causing significant declines in native mussel populations in the western Pacific.
- The study compared the intestinal microbiota, metabolomes, and digestive enzyme activities of the two competing mussel species, revealing notable differences in bacterial composition and carbohydrate-related metabolism.
- Findings indicate that the invasive mussel has higher carbohydrate-degrading capabilities and enzyme activity compared to the native species, suggesting these traits may support its survival and competition in the new environment.
Article Abstract
Biological invasion is a primary direct driver of biodiversity loss. Recently, owing to exploitation competition with an invasive mussel, (Hanley, 1843), there has been a drastic decrease in the population of native (Linnaeus, 1758) in several western Pacific regions. In the present study, intestinal microbiota, metabolome, and key digestive enzyme activities were compared between the two competing mussels, and , to elucidate the differences in intestinal microbiota and metabolic points. We observed that , , and were the three predominant bacterial phyla in the two species. The relative abundance of related to carbohydrate-degrading ability was significantly higher in than in . Compared to , different metabolites including maltose and trehalose were enriched in . Lastly, higher carbohydrases activities of alpha-amylase, cellulase, and xylanase were observed in than in . These differences might play an important role in the adaptation process of to the new environment. This study provides important basic knowledge for investigating the competition between and in terms of food resources utilization.

The Gulf of Maine holds significant ecological and economic value for fisheries and communities in north-eastern North America. However, there is apprehension regarding its vulnerability to the effects of increasing atmospheric CO. Substantial recent warming and the inflow of low alkalinity waters into the Gulf of Maine have raised concerns about the impact of ocean acidification on resident marine calcifiers (e.

Marine foundation species are increasingly impacted by anthropogenic stressors, driving a loss of diversity within these critical habitats. Prior studies suggest that species diversity within mussel beds has declined precipitously in southern California, USA, but it is unclear whether a similar loss has occurred farther north. Here, we resurvey a mussel bed community in northern California first sampled in 1941 to evaluate changes in diversity after 78 years.

Catechol-functionalized proteins in mussel holdfasts are essential for underwater adhesion and cohesion and have inspired countless synthetic polymeric materials and devices. However, as catechols are prone to oxidation, long-term performance and stability of these inventions awaits effective antioxidation strategies. In mussels, catechol-mediated interactions are stabilized by 'built-in' homeostatic redox reservoirs that restore catechols oxidized to quinones.

The influence of sex and heredity on DNA methylation in the somatic tissues of mice has been well-documented, with similar hereditary effects reported in honeybees. However, the extent to which these factors affect DNA methylation in molluscan somatic tissues remains poorly understood. In this study, we investigated genomic DNA methylation patterns in the adductor muscle of two genetically distinct oyster strains using whole-genome bisulfite sequencing (WGBS).

Recent studies have unveiled the deep sea as a rich biosphere, populated by species descended from shallow-water ancestors post-mass extinctions. Research on genomic evolution and microbial symbiosis has shed light on how these species thrive in extreme deep-sea conditions. However, early adaptation stages, particularly the roles of conserved genes and symbiotic microbes, remain inadequately understood.
