Biomonitoring surveys are therefore a key tool for ensuring biosecurity in diversity hotspots and vulnerable habitats. In this study, we use DNA barcoding to provide the first record of the viviparid, Sinotaia cf. quadrata (Benson, 1842) from North America. Reciprocal monophyly and low genetic divergence (uncorrected p-distance: 0.004) with a Bellamya quadrata (Benson, 1842) individual from the type region (China) provides strong support for this identification. The species was recovered as part of a routine biomonitoring survey of the Adirondack region of northern New York. Only three adults were recovered (no populations or juveniles) suggesting that the discovery represents a very recent arrival. Considering the proximity of the sampling site from the massive St. Lawrence River, it is likely that S. cf. quadrata was introduced into the St. Lawrence, probably via the aquarium plant trade, and was able to spread into smaller river system in northern New York and possibly other border states. This record represents the fourth alien viviparid, the third of which is of Asian origin that have made its way to New York waters. Future biomonitoring efforts for the upcoming summer period will involve targeted searches for S. cf. quadrata to determine the extent of its spread in the region.","PeriodicalId":7779,"journal":{"name":"American Malacological Bulletin","volume":"38 1","pages":"124 - 128"},"PeriodicalIF":0.5,"publicationDate":"2021-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42825003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shell characters have long been used for describing species of gastropods, even though these features may be influenced by environmental conditions. To determine the degree of phenotypic plasticity of two North American lymnaeid species, Stagnicola elodes (Say, 1821) and Stagnicola emarginata (Say, 1821), that occur in different habitats and differ in shell morphology, we reared individuals in captivity under similar conditions and compared shell shapes and sizes of wild-caught and captive-reared populations. We also exposed individuals of S. elodes to effluent from a potential predator (crayfish) to gauge the possible impact of the presence of predators on shell morphology. Although the two species remained morphologically distinct, shell shapes of captive-reared individuals of both species differ significantly from those of wild-caught individuals and show similar magnitudes of change among species. Directions of change, however, differed significantly among species. Although shell shapes of individuals of S. elodes that were exposed to crayfish cues were not significantly different from control snails, shell sizes of exposed snails were smaller than unexposed snails. These results suggest that exposure to predators affects growth rates of S. elodes. Nonetheless, given significant associations between shell shape and size that were observed in the captive-rearing and predator-exposure experiments, shell shape changes allometrically during development. These results suggest that morphological differences of other North American Stagnicola species reflect ecophenotypic variation, but more work is necessary to further evaluate this hypothesis.","PeriodicalId":7779,"journal":{"name":"American Malacological Bulletin","volume":"38 1","pages":"89 - 97"},"PeriodicalIF":0.5,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43809052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, distributions of large heteropod species are poorly known. Heteropod collections from two midwater sampling programs conducted after the 2010 Deepwater Horizon oil spill (DWHOS): the Offshore Nekton Sampling and Analysis Program (ONSAP) in 2011 and the Deep Pelagic Nekton Dynamics of the Gulf of Mexico (DEEPEND) in 2015-2018 were used for this study These programs collected over 3,495 heteropods in the two target families from 46 sampling stations in the northern Gulf of Mexico (GOM). The zone along the northeastern GOM continental slope had the greatest species richness and abundances. The family Pterotracheidae (Pterotrachea coronata (Forsskal 1775), Pterotrachea hippocampus(Philippi 1836) and Pterotrachea scutata (Gegenbaur 1855) was the most abundant and contained the largest specimens examined. Common carinariids included Carinaria lamarcki (Péron & Lesuer 1810) and Cardiapoda placenta (Lesson 1830). We found evidence of diel migration in P. coronata and P. scutata but not for C. lamarcki, C. placenta or P. hippocampus. We evaluated body and eye size at capture depth for each species. There was no evidence of eye size increasing relative to body size with depth among the five species and relative eye size is species-specific. However, it was observed that vertical migrators had a different eye-type than the non-migrators. We determined that pterotracheids have smaller eyes relative to their total body size than carinariids. The allometric pattern of eye growth differed in P. scutata from those of the other species which could indicate that a factor other than depth plays a part in heteropod eye development. This is the first comprehensive study of large heteropods in the northern GOM which provides an important baseline for continued study of this pelagic gastropod.","PeriodicalId":7779,"journal":{"name":"American Malacological Bulletin","volume":"38 1","pages":"73 - 82"},"PeriodicalIF":0.5,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45568144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 649 individuals belonging to two genera and six species were collected from nine stations at depths of 15.6 to 22 m in the dry and rainy seasons. The most abundant species were Caecum brasilicum de Folin, 1874 and Caecum floridanum Stimpson, 1851.

Among the 14 species previously recorded for the Abrolhos coral reef area, Caecum metamorphosicum is for the first time registered in the area in this study.
