Effect of trematode parasites on cockle Cerastoderma edule growth and condition index: a transplant experiment
We quantified the effect of trematode parasites in cockles through a 303 d transplant experiment. Cockles were sampled in 3 different sites on the southwest coast of France characterized by 3 different trematode communities, i.e. Royan (RO): high Meiogymnophallus minutus abundance near cockle heart, South Arguin (SA): high Himasthla interrupta abundance in the mantle margin, and North Arguin (N...
متن کاملImpact 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 کاملEmergence pattern and spatial distribution of the common cockle Cerastoderma edule
When groups of freshly collected cockles Cerastodema edule L. were transferred to laboratory conditions and exposed to cycles of tldal emersion and immersion and a light regune of 12 h light. l 2 h dark, up to 40% of the group emerged onto the surface of the substratum during emersion at the onset of darkness. This pattern of emergence decreased in intensity from 37% to 10% of all individuals e...
متن کاملThe influence of polycyclic aromatic hydrocarbons on bacteriophage development. II.
A recent publication from this laboratory1 described the inhibitory effect of certain aromatics on the replication of single-stranded RNA2 and DNA bacterial viruses using the isolated nucleic acid as the infectious agent. At the same time, it was observed that most of the aromatics that exhibited this effect were also carcinogenic. The viral replication response to hydrocarbons requires the use...
