Impact of two parasitic trematodes, Meiogymnophallus minutus and Himasthla spp., on the growth of the cockle, Cerastoderma edule
The impact of two principal parasitic digenetic trematodes, Meiogymnophallus minutus and Himasthla spp., on the growth (weight and length) of the cockle, Cerastoderma edule, in Arcachon Bay (France) was studied. The experiment was conducted in the land-based mesocosms. The velocity of infestation with both trematodes was far more rapid during summer in the cockles already parasitized with these...

متن کاملA growth model of the cockle (Cerastoderma edule L.) tested in the Oosterschelde estuary (The Netherlands)
We present an ecophysiological model of the bivalve Cerastoderma edule that simulates individual growth and reproduction under ambient conditions in temperature and food availability in the Oosterschelde estuary, SW Netherlands. The model contains feedback loops in the uptake and metabolism of food and in the partitioning of carbon to the internal state variables: somatic tissue, storage, organ...
متن کاملCell-free transmission of a haemic neoplasm in the cockle Cerastoderma edule.
A haemic neoplasm occurs in populations of the common cockle Cerastoderma edule L. along the coast of Ireland. The morphology, epizootiology and distribution of the disease have previously been described. The aetiology of the neoplasm is unknown. In this study transmission of the neoplasm between cockles was accomplished using both whole neoplastic cells and neoplastic cell-free homogenates whi...
متن کاملThe cockle Cerastoderma edule at Northeast Atlantic shores: genetic signatures of glacial refugia
The cockle Cerastoderma (Cardium) edule (L.) ranges from NW Africa to northern Scandinavia. Abundance in shallow coastal sediment is often high, and it attracts commercial harvest. In this study, a complex genetic pattern has been revealed by mitochondrial DNA in 383 individuals from 19 sampling sites. Parsimony network analysis of 79 haplotypes identified two dominant central haplotypes separa...
