Abstract The field of sclerochronology has long been known to paleobiologists. Yet, despite the central role growth rate, age, and body size in questions related macroevolution evolutionary ecology, these types studies data they produce have received only episodic attention from paleobiologists since field's inception 1960s. It is time reconsider their potential. Not can sclerochronological hel...

Cold spells, characterized by prolonged periods of low temperature, have become increasingly frequent, intense, and due to the ongoing effects climate change, resulting in devastating consequences for marine ecosystems significant socio-economic impacts. As ectothermic organisms, bivalves are dependent on their environment regulating body thus, cold spells can disrupt normal functioning, leadin...

The chemosymbiotic bivalves collected from the mud volcanoes of the Gulf of Cadiz are reviewed. Of the thirteen species closely associated with chemosynthetic settings two Solemyidae, Solemya (Petrasma) elarraichensissp. n. and Acharax gadiraesp. n., one Lucinidae, Lucinoma asapheussp. n., and one Vesicomyidae, Isorropodon megadesmussp. n. are described and compared to close relatives of their ...

Most metazoan species have strict maternal inheritance of the mitochondrial genome. In bivalves, a unique inheritance pattern called doubly uniparental inheritance (DUI) occurs in at least seven bivalve families. In this system of mitochondrial inheritance, males inherit and carry mtDNA from both parents, while females only carry mtDNA from the mother. Here, we present evidence of mitochondrial...

The proteins in the hinge ligaments of molluscan bivalves were subjected to chemotaxonomic studies according to their amino acid compositions. The hinge-ligament protein is a new class of structure proteins, and this is the first attempt to introduce chemical taxonomy into the systematics of bivalves. The hinge-ligament proteins from morphologically close species, namely mactra (superfamily Mac...

Bivalve mollusc meat—that from mussels, clams, and oysters—offers a highly sustainable nutritious alternative to meat other shellfish, fish, or livestock. However, bivalves are an unpopular mass market food relative these items, limiting our ability reap potential environmental health benefits. Hence, this study aimed assess current barriers drivers for bivalve consumption investigated whether ...

Abstract The Philippines has rich marine resources but are threatened by the effects of climate change and other activities made humans. There is an inadequate or scarcity in literature on prominent impacts country’s biodiversity, specifically ecosystem, thus this study aimed to determine diversity macro molluscan gastropods bivalves intertidal areas Ajuy, Iloilo, Western Visayas, Philippines. ...

Hemocytes are the immune effectors in clams, directing cellular but also humoral defences. In the Manila clam (Ruditapes philippinarum) and the carpet shell clam (Ruditapes decussatus), two phenotypically similar venerid species, fishery and aquaculture importance motivated scientific studies to improve knowledge about the participation of hemocytes in immune response. Currently, gaps still per...

Seagrasses evolved from terrestrial plants into marine foundation species around 100 million years ago. Their ecological success, however, remains a mystery because natural organic matter accumulation within the beds should result in toxic sediment sulfide levels. Using a meta-analysis, a field study, and a laboratory experiment, we reveal how an ancient three-stage symbiosis between seagrass, ...
