Última Description mathématique de la croissance de Lesueurigobius friesii (Teleostei, Gobiidae). Essai de synthèse ArchiMer Gros, Philippe. A population of the burrowing goby Lesueurigobius friesii was studied from 1974 to 1979, at a sampling station located on a Nephrops ground in the northem Bay of Biscay, off the south coast ofBrittany; samples were collected close to a muddy bottom, at depths ranging from 80 to 100 m. Data on demographie structures were obtained by two independent exercises: examination of oto1iths and the analysis of length-frequency distributions. The fish attains a standard length of at !east 71 mm and an age of 6 years. Most growth takes place during the first three years of !ife, and proceeds very slowly thereafter. The state of gonad development was assessed qualitatively by visual inspection of the body cavity of females; spawning occurs in spring, and by July 61 of...

One of the main challenges in ecology is to understand how global changes affect biodiversity and what are the consequences on ecosystem functioning. In this perspective, the functional diversity of communities is a cornerstone since it allows linking environment, community structure and ecosystem properties. The aim of this thesis is thus to improve the understanding of functional diversity dynamic (i) in relation to natural variability of environmental conditions and (ii) under anthropogenic disturbances. As a first step we have developed a new methodological framework allowing to (1) describe fish functional niches based on functional traits, and (2) to quantify functional diversity within (α) and among (β) sites thanks to new indices....
