“…Overall, we achieved a complete life cycle culture of the clam in the laboratory and maintained high reproductive performance during artificial breeding. This also confirms the potential of M. lateralis as a model bivalve, which is consistent with previous reports (Calabrese, 1969 ; Rhodes et al., 1975 ). Simultaneously, adaptive advantages in phenotypic traits were observed in subsequent M. lateralis generations, such as gradual increases in fertilization and larval survival, providing evidence of the species' adaptation to laboratory conditions.…”

The dwarf surf clam, Mulinia lateralis, is considered as a model species for bivalves because of its rapid growth and short generation time. Recently, successful breeding of this species for multiple generations in our laboratory revealed its acquisition of adaptive advantages during artificial breeding. In this study, 310 individuals from five different generations were genotyped with 22,196 single nucleotide polymorphisms (SNPs) with the aim of uncovering the genetic basis of their adaptation to laboratory conditions. Results revealed that M. lateralis consistently maintained high genetic diversity across generations, characterized by high observed heterozygosity (Ho: 0.2733–0.2934) and low levels of inbreeding (Fis: −0.0244–0.0261). Population analysis indicated low levels of genetic differentiation among generations of M. lateralis during artificial breeding (Fst <0.05). In total, 316 genomic regions exhibited divergent selection, with 168 regions under positive selection. Furthermore, 227 candidate genes were identified in the positive selection regions, which have functions including growth, stress resistance, and reproduction. Notably, certain selection signatures with significantly higher Fst value were detected in genes associated with male reproduction, such as GAL3ST1, IFT88, and TSSK2, which were significantly upregulated during artificial breeding. This suggests a potential role of sperm‐associated genes in the rapid evolutionary response of M. lateralis to selection in laboratory conditions. Overall, our findings highlight the phenotypic and genetic changes, as well as selection signatures, in M. lateralis during artificial breeding. This contributes to understanding their adaptation to laboratory conditions and underscores the potential for using this species to explore the adaptive evolution of bivalves.

“…The large surf clams (6-12 cm long) used in this study were collected by hand from shallow beds in coastal waters near Point Judith, R.I. The small clams used in this study were obtained from stock reared at NMFS Milford Laboratory (Rhodes et al 1975). All animals were maintained in the laboratory in running seawater at laboratory ambient conditions for at least 2 weeks before experimentation.…”

is a 39,000-km-sector of the Middle Atlantic continental shelf between Montauk Point, N.Y., and Cape May, N.J., approximately 180 km wide from the Hudson-Raritan estuary to the shelf edge. Depths range between 30 and 60 m over much of the Bight, with the inner shelf off New Jersey being somewhat shoaler than that off Long Island. The shelf break generally occurs at a depth of 140 m. The most prominent topographic NOAA PROFESSIONAL PAPER 11 feature of the shelf is the Hudson Shelf Valley, a broad, shallow channel extending from the Bight Apex seaward to the outer shelf and Hudson Canyon (fig. 1-1). The surface of the shelf is a gently rolling plain that gradually increases in depth from the Apex at the mouth of the Hudson River to the edge of the shelf, a gradient of about 60 m in 100 km. North of the Hudson Shelf Valley the surface is veneered with sand. To the south, the surficial sediments are sand and gravel. Within the valley, nutrientrich muds have accumulated since the postglacial sea began to rise. Barrier beaches, bluffs, and estuaries are prominent coastal features of the Bight. Water movements in the Bight are highly variable in space and time. Over the middle and outer portions of the shelf, waters generally move to the southwest, parallel to the bathymetric contours. In the inner (nearshore) portion of the Bight, water movement and structure of the water systems Analysis Program Office. Environmental Research Laboratories, Boulder. Colo., 189 pp

“…Muliniu lateralis (Say) is a small (15-20 mm) euryhaline bivalve (family Mactrididae) commonly found in sandy/ muddy sediments [22,23]. Geographically, it ranges from Prince Edward Island, Canada, to northeastern Mexico and the West Indies [24]. It is an opportunistic species, often exhibiting rapid population fluctuations.…”

Over the last 10 years a great deal of research effort has concentrated on determining the effects of contaminated sediments on aquatic organisms. For marine systems, this effort has emphasized acute sediment toxicity tests using amphipods, although a variety of other end points and species have been used. Another candidate species for marine, solid-phase, sublethal sediment toxicity testing is the bivalve Mulinia lateralis. Useful attributes of this euryhaline bivalve include a wide geographic distribution (along the North American Atlantic coast from Prince Edward Island to the Gulf of Mexico), easy lab culture, and amenability to toxicity testing applications (end points are mortality and growth [milligrams per organism dry weight]). Detailed in this paper are organism selection and culture, establishment of statistical design, and an estimate of organism mortality and sublethal response variability. Results of Mulinia lateralis toxicity tests with 65 contaminated sediments from eight sites are reported, as well as results of comparative toxicity tests using two amphipod species, Ampeliscu abdita and Eohaustorius estuarius. Analysis of statistical power indicates treatment weight and survival responses that are 25% different from the site control responses can be detected with a probability of 95%. Results of comparative toxicity tests illustrate that although Mulinia iateralis and amphipod acute end points are relatively similar in sensitivity, utilization of the Mulinia lateralis sublethal growth end point greatly increases test sensitivity. This paper describes a new marine sediment toxicity test that complements the existing suite of marine sediment toxicity assessment techniques.
