| The research programme developed within in the framework of the project study of the Paluel site allowed us to highlight, near the drainage channel of the Durdent, a sea trout fishery using fixed nets in the area of the swaying of the tides. This activity, very much in use in the eastern English Channel and along the southern shoreline of the North Sea, not only for catching certain amphibiotic species but also species that are strictly of the sea, represents a sizeable cause of the mortality rate for salmonid populations during their coastal migrations. The studies begun on this fishery in 1980 have as their goal to assess the size of the salmonid catches near the site, especially of sea trout, and to acquire more complete knowledge of the catch, biology... |

| With the advent of deep submergence research vessels (DSRVs) biological and ecological studies of ocean deeps have made great strides. Especially these submersibles allowed to conduct physiological and biochemical experiments on benthic fauna directly on the bottom or on board with alive retrieved animals. A second great interest is the possibility to work in chaotic areas and on microenvironments. Without DSRVs most of measurements and observations obtained on hydrothermals vents would had been impossible. We will present the different equipment designed for the two French DSRVs used during the cruises conducted by the Departement "Environnement Profond" de l'IFREMER to study hydrothermal and "normal" deep-sea ecosystems. We will discuss the new devices... |

| The metropolitan region of Recife, Brazil is endemic for Dirofilaria immitis and has an environment favorable to the development of Culex quinquefasciatus. The goal of this study was to evaluate the vector competence of the Cx. quinquefasciatus RECIFE population for D. immitis transmission. A total of 2,104 females of Cx. quinquefasciatus RECIFE population were exposed to different densities of D. immitis microfilariae blood meals, ranging from 1,820 to 2,900 mf/ml of blood, in a natural membrane apparatus. The results showed a variation between 92.3% and 98.8% of females fed. The exposure of the Cx. quinquefasciatus RECIFE population to different densities of microfilariae did not influence the mortality of the mosquitoes. Infective larvae from D. immitis... |
