Bivalve impacts in freshwater and marine ecosystems

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, … Continue reading Bivalve impacts in freshwater and marine ecosystems

Pathogens of marine bivalves in Maine (USA): A historical perspective

Shellfish aquaculture (in particular oyster cultivation) has the potential to play a significant role in refreshing the coastal economy in the state of Maine (USA). Although ocean warming and acidification are often listed as the primary manifestations of climate change in the marine environment, the issue of expanding geographic ranges of parasites and pathogens is … Continue reading Pathogens of marine bivalves in Maine (USA): A historical perspective

Laboratory simulation reveals significant impacts of ocean acidification on microbial community composition and host-pathogen interactions between the blood clam and Vibrio harveyi

It has been suggested that climate change may promote the outbreaks of diseases in the sea through altering the host susceptibility, the pathogen virulence, and the host-pathogen interaction. However, the impacts of ocean acidification (OA) on the pathogen components of bacterial community and the host-pathogen interaction of marine bivalves are still poorly understood. Therefore, 16S … Continue reading Laboratory simulation reveals significant impacts of ocean acidification on microbial community composition and host-pathogen interactions between the blood clam and Vibrio harveyi

Review of parasites and pathologies of the main bivalve species of commercial interest of Argentina and Uruguay, southwestern Atlantic coast

A systematic review of the parasites and pathologies of the main important commercially bivalve species from Argentina and Uruguay has been done. Bacteria, algae, Perkinsozoa, Haplosporidia, Ciliophora, Apicomplexa, Turbellaria, Trematoda, Cestoda and Nemertea have been found infecting natural populations of bivalve species. Disseminated neoplasia has been recorded in mussels from culture causing gonadal castration and … Continue reading Review of parasites and pathologies of the main bivalve species of commercial interest of Argentina and Uruguay, southwestern Atlantic coast

Ocean acidification and pathogen exposure modulate the immune response of the edible mussel Mytilus chilensis

Ocean acidification (OA) is one of the main consequences of increasing atmospheric carbon dioxide (CO2), impacting key biological processes of marine organisms such as development, growth and immune response. However, there are scarce studies on the influence of OA on marine invertebrates' ability to cope with pathogens. This study evaluated the single and combined effects … Continue reading Ocean acidification and pathogen exposure modulate the immune response of the edible mussel Mytilus chilensis
