The double life of Bulimus ovoideus Bruguière, 1789: taxonomic implications for Streptaxidae and Camaenidae (Mollusca, Stylommatophora) Molluscan Res. (IF 1.0) Pub Date : 2023-04-29 Frank Köhler, David Herbert, Ben Rowson, Gary Rosenberg
ABSTRACT The name Bulimus ovoideus Bruguière, 1789 is in current use for two different species, one from East Africa and one from the Philippines. The name has also been declared as the type species of both Edentulina Pfeiffer, 1856 (Streptaxidae) and Cochlostyla Férussac, 1821 (Camaenidae). We demonstrate that the use of this name for a Philippine camaenid is based on an early misidentification. To

Uncovering the biodiversity of New Zealand Solenogastres (Mollusca, Aplacophora) with three new species of Proneomeniidae Simroth, 1893 and new data for Dorymenia quincarinata (Ponder, 1970) Molluscan Res. (IF 1.0) Pub Date : 2022-11-25 Madelyn G. McCutcheon, Kevin M. Kocot, M. Carmen Cobo
ABSTRACT Aplacophorans are vermiform marine molluscs found in benthic habitats worldwide. However, there is an extreme lack of knowledge about their true diversity. There are around 440 described species, but the true number is estimated to be at least tenfold higher. Identifying most solenogaster aplacophorans to the species, genus and sometimes even family level requires histology so that internal

ABSTRACT This study determined the seasonality of Magallana bilineata spat settlement in a natural oyster bed and established surface texture preference of competent larvae by comparing the numbers of spat settling on the smooth and rough surfaces of ceramic tiles over a period of 31 months. This will guide farmers when to deploy cultches to maximise spat harvest. Regardless of tile orientation, spat

Resolving the taxonomic ambiguity of Sepia ramani using integrative taxonomy Molluscan Res. (IF 1.0) Pub Date : 2022-05-05 Sneha Vargheese, V. S. Basheer
ABSTRACT Sepia pharaonis Ehrenberg, 1831 is a commercially important cuttlefish species in India and other countries. Researchers have found that Sepia pharaonis populations in different regions show morphological and genetic differences, and some have suggested that Sepia pharaonis should be considered a species complex. Sepia ramani Neethiselvan, 2001 was described from the southeast coast of India

Clearance of Escherichia coli by the freshwater mussel Lamellidens marginalis in laboratory conditions Molluscan Res. (IF 1.0) Pub Date : 2022-05-03 Md. Firoz Shah, Md. Abdullah Al Mamun, Muhammad Tofazzal Hossain, Mohammad Moniruzzaman, Selina Yeasmine, Md. Helal Uddin, M. Jasim Uddin
ABSTRACT Scientists and environmentalists are searching for biological remedies to reduce E. coli concentrations in waterbodies to acceptable levels. The present research was conducted to investigate clearance of E. coli isolated from freshwater mussels (Lamellidens marginalis) in the Old Brahmaputra River, Mymensingh, Bangladesh by conspecific mussels from the same river in aquarium conditions. Mussels

Long-distance dispersal from island to island: colonisation of an oceanic island in the vicinity of the Asian continent by the land snail genus Karaftohelix (Gastropoda: Camaenidae) Molluscan Res. (IF 1.0) Pub Date : 2022-04-29 Kazuki Kimura, Satoshi Chiba, Larisa Prozorova, Jae Hong Pak
ABSTRACT Ullung Island is an oceanic island in the Sea of Japan about 130 km distant from the Korean peninsula. The biota of this oceanic island is thought to be derived from the closest continental region while the importance of long-distance dispersal from other areas for the formation of the Ullung Island biota was considered negligible. In this study, we have examined the origin of the Ullung Island-endemic

Onchidium reevesii may be able to distinguish low-frequency sound to discriminate the state of tides Molluscan Res. (IF 1.0) Pub Date : 2022-04-25 Rongcheng Rao, Heding Shen
ABSTRACT In order to study how Onchidium reevesii predict tides, the cDNA encoding the precursor of the pedal peptide (Pep), a neuropeptide that plays an important role in neuromotor regulation, was cloned by RACE (Rapid Amplification of cDNA Ends) technology. Bioinformatics analysis was carried out on the sequence of the cloned cDNA. The frequency spectra of the intertidal zone were obtained and Quantitative

Phenotypic plasticity of the invasive apple snail, Pomacea canaliculata, in China: a morphological differentiation analysis Molluscan Res. (IF 1.0) Pub Date : 2022-04-21 Mingzhu Luo, Benliang Zhao, Jiaen Zhang, Zhong Qin
ABSTRACT Pomacea canaliculata is listed among the world’s 100 worst invasive species, for threatening rice production and wetland biodiversity. We compared morphological and genetic characteristics of the 14 P. canaliculata geographic populations in mainland China to explore morphological differentiation in relation to geographical isolation and climate effects. The results showed that the average

Subterranean Tateidae (Gastropoda; Caenogastropoda; Truncatelloidea) from the Ngalia Basin, Northern Territory, Australia Molluscan Res. (IF 1.0) Pub Date : 2022-03-28 Winston F. Ponder, William F. Humphreys, Michael E. Shea, Gaynor Dolman, Francesco Criscione
ABSTRACT A new tateid genus, Ngalidrobia n. gen., containing six new species, is described from groundwater sampled from wells in the Ngalia Basin in the Northern Territory, Australia. The new species differ in their shell morphology which ranges from near planispiral to conical. Of these species, two live in sympatry in one location, the remainder being allopatric. Of the named tateid genera, Ngalidrobia
