Efficiency of mixed-fisheries management and operational implementation of the ecosystem approach to fisheries management rely on the ability to understand and describe the technical and biological interactions between fleets, gears and species. The present study aims to describe fine-scale spatial patterns of the French demersal mixed fisheries in...

Circadian rhythms are strongly affected by drugs. In rodents, chronic methamphetamine (METH) intake changes circadian activity rhythms, mainly by altering light synchronization that generates the expression of a free-running rhythm with a period longer than 24 h and a second behavioral component that is independent of the main suprachiasmatic (SCN)...

The drive to eat is regulated by two compensatory brain pathways termed as homeostatic and hedonic. Hypothalamic orexinergic (ORX) neurons regulate metabolism, feeding and reward, thus controlling physiological and hedonic appetite. Circadian regulation of feeding, metabolism and rhythmic activity of ORX cells are driven by the brain suprachiasmati...

This report presents the calibration of the EDA model in France, Spain and Portugal during the SUDOANG project. The objective was to predict escapement of silver eel. https://sudoang.eu/en/task-groups/. Some of the outputs are detailed in the Atlas. https://www.researchgate.net/publication/357909065_Atlas_of_European_eel_distribution_Anguilla_angui...

The SUDOANG project aims at providing common tools to managers to support eel conservation in the SUDOE area (Spain, France and Portugal). VISUANG is the SUDOANG Interactive Web Application that will host all these tools. The application consists of an eel distribution atlas (GT1), assessments of mortalities caused by turbines and an atlas showing...

Mistrust between scientists and non-scientist stakeholders is a key challenge in fishery management. The support of management with complex models is difficult, as these models cannot easily communicate their results to end users, resulting in a lack of confidence. As an example, the complex life cycle of the European eel raises problems of coordin...

Le déclin mondial des anguilles tempérées est lié aux effets combinés de multiples pressions anthropiques. Cependant, la complexité du cycle de vie des anguilles et leurs capacités d’adaptation font qu’il est très difficile de connaître le poids relatif de chacune des pressions. Leurs panmixies et les longues dérives larvaires sont des freins aux a...

Temperate eels Anguilla anguilla (European eel), A. rostrata (American eel) and A. japonica (Japanese eel) are three catadromous species which have been declining since the 1970s/1980s despite their remarkable adaptive capacity. Because of their specific life cycles, which share distant oceanic spawning grounds and continental growth stage, eels ar...

The worldwide decline of temperate eels is due to a synergistic combination of several anthropogenic pressures. However, eels display very specific life-cycles and amazing adaptation capacities that impair our ability to assess the relative effects of each pressure. Temperate eels are three catadromous species with large spatially distribution area...

Temperate eels are three panmictic catadromous species with a long period of oceanic passive larval drift and large distribution areas in contrasting environments. Spatial patterns of life history traits have been observed, and are correlated with environmental gradients, and may arise from both adaptive phenotypic plasticity and genetic polymorphi...

In mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus is the site of the main circadian clock, synchronized by the light-dark cycle, which generates behavioral rhythms like feeding, drinking and activity. Notwithstanding, the main role of the SCN clock on the control of all circadian rhythms has been questioned due to the presence of cl...

The European eel (Anguilla anguilla), and generally, temperate eels, are relevant species for studying adaptive mechanisms to environmental variability because of their large distribution areas and their limited capacity of local adaptation. In this context, GenEveel, an individual-based optimization model, was developed to explore the role of adap...
