Última Mécanismes sous-jacents du contrôle bottom-up des populations de sardines dans le Golfe du Lion : enseignements tirés des expériences et de la modélisation ArchiMer Queiros, Quentin. The Gulf of Lions has faced a sharp drop in the catches of its two main small pelagic exploited species, the sardine Sardina pilchardus and the anchovy Engraulis encrasicolus since the mid-2000s, despite both population abundances remaining high. This situation has been due to a severe decrease in individual body condition and size as a result of both lower growth and the disappearance of the oldest and largest individuals. While overfishing, predation or disease outbreaks have been refuted to explain this situation, one major hypothesis remained to be investigated. A potential shift in sardine and anchovy diet towards smaller planktonic prey indeed suggested bottom-up control as the main driver of these populations in the Gulf of Lions. The first aim of...

Ano: 2019 URL: https://archimer.ifremer.fr/doc/00692/80420/83556.pdf Modelisation analytique et caracterisation experimentale du comportement de cables synthetiques ArchiMer Ghoreishi, Reza. Cables are in general structural elements with the ability to support the axial load and the relatively light tautness of torsion and flexion. There are, in the literature, several studies concerning metallic cables, and references characteristic of synthetic cables that interest us. And yet the mechanical behaviour of synthetic cables is still poorly understood. These studies include two parts: Development of a mechanical behaviour model of the cable and model validation via tests at scale 1. These cables are characterised by a hierarchical structure, whence the serial use of two scale-transition models in order to pass from the behaviour of fibre to that of cable. The complexity of this geometry points the modelling in the direction of analytical...
