Continental margins are transitional areas between the land and deep ocean where large amounts of particulate matter supplied, transported, ultimately deposited in sea. High-energy hydrodynamic processes such as storms, currents, or internal waves tides, well bottom trawling activities contribute to resuspension remobilization these particles. These mechanisms favor their transference from cont...
The development and installation of artificial reefs involves solving several practical problems at once: increasing biological productivity, accelerating the processes natural water purification from nutrients, recreational potential area, improving efficiency fishing, they should also serve as breakwaters, protect coastline erosion prevent bottom trawling. Currently, new environmentally frien...
Abstract Most studies about benthic community use small-scale sampling methods focused on the infauna such as grabs or box-corers. The data collected by scientific trawl surveys in all European waters, frame of Common Fishery Policy Data Collection Multiannual Program, can be used to study impact large-scale fisheries trawling. However, catchability trawls is very dependent nature seabed well r...
Conservation diagnosis should identify which demographic parameters (or vital rates) are having a negative effect on the population growth rate of a threatened organism. Diagnosis can analyse how the environment is influencing the vital rates of this organism. In the present study, we tried to improve the diagnosis of a critically endangered seabird, the Balearic shearwater Puffinus mauretanicu...
