Abstract:

A study of the distribution of the commercial gastropod and bivalve in western Sarawak (Kuching, Bau, Lund and Sematan) was conducted for the purpose of its population distribution mapping. There are seven and four species of commercial gastropods and bivalves identified respectively. Five species of gastropods and two species of bivalves had been found in the mangrove swamp habitat and two species of gastropod and bivalves, respectively, had been identified in freshwater habitat. Distribution of commercial gastropod and bivalve in the mangrove swamp and freshwater habitats were strongly influ

Community composition of the infaunal bivalve fauna of the St. Lucie Estuary and southern Indian River Lagoon, eastern Florida was sampled quarterly for 10 years as part of a long-term benthic monitoring program. A total of 38,514 bivalves of 137 taxa were collected and identified. We utilized this data, along with sediment samples and environmental measurements gathered concurrently, to assess the community composition, distribution, and ecological drivers of the infaunal bivalves of this estuary system.

A year-long survey of Octopus bimaculoides Pickford & McConnaughey (1949) dens in three different subtidal habitats was conducted in Mission Bay, California. Habitat complexity and stability were positively associated with prey species richness, species abundance, and den availability. Collectively, 38 species of bivalves and 22 species of gastropods were recorded from octopi debris fields. Two species of bivalve at each site comprised approximately 60% or greater of the bivalves in the debris fields. Bivalves species represented 85% of the take, the remainder being gastropods.

Abstract:

The frequent late Cenozoic glacial ages were accompanied by sea-level falls of 100–150 m amplitude. These falls stranded the complex inner-reef platforms and lagoons of tropical Pacific islands, while outer-reef-slope habitats persisted, although displaced downslope. The effects of glacial regressions on bivalves were studied by examining the zonation of species across reef systems and species composition on tectonically uplifted islands, islands with, effectively, local low sea stands. I show that qualitative habitat loss (the stranding of inner-reef habitats) was responsible for the local ex

To assess the state of knowledge, the Information Sheet on Ramsar Wetlands (RIS) for marine and coastal Sites was searched for evidence that bivalve-reef habitat is present in the site.

Abstract:

Bivalve molluscs are abundant in marine and freshwater ecosystems and perform important ecological functions. Bivalves have epifaunal or infaunal lifestyles but are largely filter feeders that couple the water column and benthos. Bivalve ecology is a large field of study, but few comparisons among aquatic ecosystems or lifestyles have been conducted. Bivalves impact nutrient cycling, create and modify habitat, and affect food webs directly (i.e., prey) and indirectly (i.e., movement of nutrients and energy). Materials accumulated in soft tissue and shells are used as environmental monitors. Fr

ABSTRACT Introduced species often have negative effects on native species that occupy the same habitats in the area of introduction. Habitat preferences of organisms can therefore play a large role in determining the severity of interactions such as competition or predation. Previous laboratory studies have shown that the introduced mussel species Perna viridis can decrease the settlement and early survival of the native oyster species Crassostrea virginica. Both species can often be found in the same general areas, but it is unknown whether this habitat overlap is complete, or whether there a

Abstract:

The waters of Taman Nasional Bali Barat are one of the waters that have abundant diversity of marine ecosystems. Seagrass is an ecosystem that has many benefits for organisms that live in it, one of which is bivalves. Bivalves can be used as jewelry, food sources, and are often used as bioindicators of pollution. Seagrass and bivalves have the same characteristics related to the type of substrate that serve as habitat and need each other in both growth and reproduction processes. This study aims to determine the condition of seagrass cover, the abundance and diversity of bivalves, and the rela

Abstract Geothermal energy provides an important resource in Antarctic marine ecosystems, exemplified by the recent discovery of large-sized chemosymbiotic vesicomyid bivalves (subfamily Pliocardiinae) in the Southern Ocean. These clams, which we identified as Archivesica s.l. puertodeseadoi, have been reported as dead shells in areas previously covered by Larsen A and B ice shelves (eastern Antarctic Peninsula) and as live animals from active hydrothermal sites in the Kemp Caldera (South Sandwich Arc) at depths of 852–1487 m.

Abstract:

The type material of Ilionia prisca (Hisinger) is redescribed. This species shows several basic morphological characteristics typical of Recent Lucinacea, including an anteriorly expanded shell with conspicuous diagonal sulci, a hypertrophied anterior adductor muscle scar, and a nonsinuate pallial line. It is believed to have been a suspension feeder provided with a posterior exhalant siphon and capable of forming an anterior inhalant mucus tube in the sediment. Ilionia prisca lived in a habitat unfavorable for most other bivalves, deeply buried in a soft, oxygen-poor and sulphur-rich mud, in

Abstract:

Numerous environmental and intrinsic biotic factors have been sought to explain patterns in diversity and turnover. Using taxonomically vetted and sampling-standardized data sets of more than 50,000 taxonomic occurrences in the Paleobiology Database (PaleoDB) we tested whether habitat breadth predicts genus durations and diversity dynamics of marine Mesozoic bivalves, and whether this effect is independent of the well-known positive relationship between geographic range and longevity. We defined the habitat breadth of a genus as a function of its realized ranges in water depth, substrate type,

The deep brine pools of the Red Sea comprise extreme, inhospitable habitats yet house microbial communities that potentially may fuel adjacent fauna. We here describe a novel bivalve from a deep-sea (1525 m) brine pool in the Red Sea, where conditions of high salinity, lowered pH, partial anoxia and high temperatures are prevalent. Remotely operated vehicle (ROV) footage showed that the bivalves were present in a narrow (20 cm) band along the rim of the brine pool, suggesting that it is not only tolerant of such extreme conditions but is also limited to them. The bivalve is a member of the Cor

This paper proposes a texture-enhanced network (TENet) for intertidal sediment and habitat classification using multiband multipolarization synthetic aperture radar (SAR) images. The architecture introduces the texture enhancement module (TEM) into the UNet framework to explicitly learn global texture information from SAR images. The study sites are chosen from the northern part of the intertidal zones in the German Wadden Sea. Results show that the presented TENet model is able to detail the intertidal surface types, including land, seagrass, bivalves, bright sands/beach, water, sediments, an

Intertidal landscapes are highly complex and dynamic habitats that exhibit variability over a range of spatial and temporal scales. The spatial arrangement of structure-forming biogenic features such as seagrasses and bivalves influences ecosystem function and the provision of important ecosystem services, though quantification and monitoring of intertidal landscape structure has been hindered by challenges collecting spatial data in the coastal zone. In this study, an intertidal landscape mosaic of eelgrass ( Zostera marina) and blue mussels ( Mytilus edulis) was observed using low-altitude a

On the Atlantic coast of North America, chitons have been reported in subtidal habitats from Newfoundland (Canada) to New England (USA). Here, we report the finding of Boreochiton ruber in an intertidal habitat in Nova Scotia (Canada). After surveying various coastal locations across Nova Scotia for 20 years (2004 to 2024), this was the only intertidal chiton we ever found, making this an extremely rare occurrence.

For the Bay, it is concluded that removal of phosphorus only is less effective than nitrogen in improving bottom water DO beca

The updated version includes 13 new species among which three are exotics (non-Mediterranean species), five rare, two new deep sea and one previously considered a fossil species. Also, as a result of new resources, the distributions of pre-existing native molluscs have been updated to include new habitat areas. The nomenclature is also up to date based on the CLEMAM Database.
