Bivalve mollusks in Ulsan Bay (Korea) [PDF]

open access: yesThe Korean Journal of Malacology, 2014
The bivalve molluscan fauna of Ulsan Bay, East Sea coast of Korea, is summarized, based on original and literature data. The fauna consists of 61 species belonging to 20 families. Seven species are identified only to genus level. Two species (Carditellopsis toneana (Yokoyama, 1922), Carditidae and Fulvia hungerfordi (G.B. Sowerby III, 1901), Cardiidae)

Structural and Functional Stability of Natural Actomyosin From Freshwater Snail (Bellamya bengalensis): Unraveling Thermal and pH Effects

open access: yesFood Chemistry International, EarlyView.
Natural actomyosin from B. bengalensis exhibited maximum solubility (∼69.9%) at 40°C and stability near neutral pH, with minimum solubility at pH 4. Surface hydrophobicity and emulsifying activity peaked at 50°C, whereas Ca2+‐ATPase and foaming peaked at 40°C. DSC and SDS–PAGE confirmed denaturation above 40°C.

Geochemical properties of shells of Arctica islandica (Bivalvia) - implications for environmental and climatic change [PDF]

open access: yes, 2010
Trace elemental concentrations of bivalve shells content a wealthy of environmental and climatic information of the past, and therefore the studies of trace elemental distributions in bivalve shells gained increasing interest lately.

Phylogenetic support values are not necessarily informative : the case of the Serialia hypothesis (a mollusk phylogeny) [PDF]

open access: yes, 2009
Background: Molecular phylogenies are being published increasingly and many biologists rely on the most recent topologies. However, different phylogenetic trees often contain conflicting results and contradict significant background data. Not knowing how

Where’s Waldo? A new commensal species, Waldo arthuri (Mollusca, Bivalvia, Galeommatidae), from the Northeastern Pacific Ocean

open access: yesZooKeys, 2013
A galeommatid bivalve mollusk, representing a new species, is described from off the coasts of California and Vancouver Island, British Columbia. The new bivalve has a commensal relationship with the heart urchin, Brisaster latifrons.

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

open access: yesGeological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

The complete mitochondrial genome of Mactra chinensis (Bivalvia: Macridae)

open access: yesMitochondrial DNA. Part B. Resources, 2021
The structure and composition of the mitogenome of a bivalve mollusk, denoted as Mactra sp. (MT780813), has been obtained. The genome has a variable organization: it includes 12 protein-coding genes, 28 tRNAs, and two rRNA genes.

Impact of the species ratio in polyculture on growth and weight of bivalve mollusks in the Tauiskaya Guba Bay, Okhotsk Sea

open access: yesИзвестия ТИНРО, 2021
Linear growth and weight of bivalve mollusks cultivated in polyculture are considered. Cages with three mollusk species, as blue mussel, long-necked clam (mya), and macoma, were hanged at the depth of 1.0–1.5 m in the Tauiskaya Guba Bay, Okhotsk Sea ...

Ostracod faunal and geochemical evidence for the impact of Hoxnian (MIS 11c) sea levels in eastern England

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Marine isotope substage 11c (~426–366 ka) is widely regarded as the most recent Pleistocene interglacial that is broadly analogous to the Holocene. The timing and magnitude of sea‐level changes during MIS 11 have been much debated, particularly concerning whether sea levels were significantly higher than during the Holocene. Empirical evidence
