Worldwide kelp forests have been the focus of several studies concerning ecosystems dysfunction in the past decades. Multifactorial kelp threats have been described and include deforestation due to human impact, cascading effects and climate change. Here, we compared community and trophic structure in two contrasting kelp forests off the coasts of Brittany. One has been harvested five years before sampling and shelters abundant omnivorous predators, almost absent from the other, which has been treated as preserved from kelp harvest. δ15N analyses conducted on the overall communities were linked to the tropho-functional structure of different strata featuring these forests (stipe and holdfast of canopy kelp and rock). Our results yielded site-to-site...

Etude bibliographique de quelques espèces planctoniques et benthiques littorales de la Manche - Volume 4 - Espèces phytobenthiques
Provedor de dados: 5
Autores: Belsher, Thomas; Bove, J; De Cayeux, M.b.
This document is the fourth volume of a bibliographical survey of some of the species studied by IFREMER Brest's Coastal Environment Department (DEL) on a regular basis. It consists of an exhaustive review of the up-to-date knowledge on four of those species, both highly used in the French algae industry and commonly met in the marine domain of thermo-nuclear plants: -Laminaria digitata (Linné) Lamouroux -Laminaria hyperborea (Gunnerus) Foslie -Fucus serratus Linné -Ascophyllum nodosum (Linné) Le Jolis A general bibliography survey on Kelps and Fucales concludes the document.

Introduction  During the month of April 1994, the "Ressources Halieutiques de l'Ifremer" laboratory (Ifremer Halieutic Resources) in Brest tested tools to be used for the harvesting of Laminaria hyperborea as requested by Système Bio-Industries. The first results of this trial campaign are as follows: The tools are effective as far as interspecific as well as intraspecific selectivity. Rightly so, Laminaria hyperborea accounts for nearly 100% of the harvest. We also noticed that only large size plants are harvested, commercial harvest is satisfactory in terms of yield. However insufficiencies still remain. Comb efficiency is low, since the actual harvest only represents 10 to 12% of the stipes collected when the machine goes through.  This low efficiency...
