In contrast to tropical environments, Mediterranean fish assemblages have been exposed to greater seasonal fluctuations of climatic factors (water temperature, photoperiod), which have impacted more or less significantly on the biology of fish. The labrid fishes (wrasses) are good examples of how climatic changes influence behavioural strategies. The European wrasses differ mainly from the tropical ones by their particular reproductive behavioural patterns. In these wrasses, the variety of the reproductive strategies (hermaphroditism or gonochorism, spawning seasonality in open water or on substrates, degrees of parental care, etc.) make it possible to study the evolution of these strategies. If in tropics, most of wrasses exhibit planktonic spawning, the Mediterranean ones adapted their behaviour, developing modes of reproduction unusual in tropics: short periods of reproduction, spawning eggs on substrates or in elaborated nest, parental cares. This evolution is dictated, in particular, by the pressure of climatic factors, such as water temperature on the presence or the absence of parental care. Of the 21 Mediterranean species, almost all the species studied lay their eggs on substrates or in a nest built by the large territorial male. Only Coris julis, Thalassoma pavo and Xyrichthys novacula (protogynous hermaphroditism fishes) spawn in open water (planktonic spawning) as tropical species do. Moreover, the majority of Symphodus males have complex social structures where nesting territorial, satellite and sneaker males can be recognised. These sneakers adopt reproductive behavioural patterns known as alternative reproductive behaviour. They can either steal the spawn (streaking), or steal the female (sneaking). Finally, the majority of these Symphodus give parental care throughout each nesting cycle (2 to 5 nests are elaborated during the reproductive season in spring), which always comprises three phases: nest building phase (construction with alive algae of a substrate for spawning or a true nest in form of cup), sexual activity phase (the very moment the females come to spawn in the nest) and fanning phase (oxygenation of eggs, by the beat of the pectoral fins, until hatching). The diversity of the biological and behavioural adaptations developed by the numerous tropical and temperate species of labrid fishes allow us to consider the family as an ideal group to investigate various problems in behavioural ecology.

L'assistance technique dite «programme de stewardship» a été initiée par les donateurs au Rwanda en 1998, avec l'aide du Consortium IPHYTROP, conformément aux «Lignes directrices sur l'aide et l'environnement N"6" de l'OCDE (1995). Elle vise à accompagner les achats de pesticides et à responsabiliser tous les acteurs de la filière et en priorité les producteurs. Pour la première fois durant la campagne 1999/2000, au Mali, au Burkina Faso et au Tchad, un programme de stewardship complet destiné aux utilisateurs de pesticides a été réalisé dans le cadre des Appels d'Offres pour l'achat des produits phytosanitaires. Ce programme, financé par SENCHIM-AG, a été proposé afin d'apporter d'une part, un complément de formation technique en matière de lutte phytosanitaire et d'autre part, de communiquer sur le terrain aux encadreurs et aux agriculteurs les éléments essentiels sur les produits fournis et à les conscientiser quant aux risques liés à l'utilisation des produits phytosanitaires (insecticides, herbicides, fongicides). C'est l'intérêt de tous les acteurs d'accompagner désormais systématiquement les livraisons de produits phytosanitaires de tels programmes de formation. L'article se propose d'exposer le programme réalisé, les. contraintes rencontrées et les enseignements tirés de ces trois premières expériences. [less ▲]

A hydrodynamical model of the general circulation in the Black Sea has been build up, using the GHER (GeoHydrodynamics and Environment Research) three-dimensional, non-linear, baroclinic, turbulent closure model. A model with 5 km horizontal resolution and 25 vertical levels is used to compute the typical seasonal cycle by forcing the model with climatological monthly mean fields of temperature, salinity and wind stress at the air-sea interface. Furthermore, the river discharges of the Danube, the Dnestr and the Dnepr are taken into account. This high resolulion model resolves the baroclinic instabilities generated by the interactions of the boundary current with the coastline geometry or with the continental shelf/slope topography. A simple ecosystem model defined by a nitrogen cycle is coupled with Ihe hydrodynamical model. The state variables of this model are defined as those which are necessary and sufficient to assess the effects of the physical processes, and in particular of the boundary current instability , on the space time distribution of the primary and secondary productions. The results of the 3D ecohydrodynamic model are compared with CZCS data of surface chlorophyll fields collected during the period from 1978 to 1986. [less ▲]

Finite element simulations involving large deformations and large displacements imply the setting up of a precise kinematic for the integration scheme. Moreover, anisotropic mechanical behaviors have to be expressed in an appropriate local reference frame. In the present paper, a computational procedure is derived from a particular velocity gradient de¯nition. The implementation in the ¯nite element code Lagamine developed in the M&S department is described. An application to a simple shear test is proposed. A sinusoidal behavior of the shear component stress is emphasized. It is due to the anisotropic yield locus and appears in the case of a saturated isotropic hardening law. [less ▲]

The pulmonary autograft operation consists of an aortic replacement using the autologous pulmonary valve. The pulmonary valve is substituted by a cryopreserved pulmonary homograft. This operation is in fact a delicate double valve replacement whose benefits are linked to the viability of the new aortic substitute. The pulmonary autograft has superb hemodynamic features and very low thrombogenicity. The report of a selected observation offers the occasion of defining the current indications of this operation in aortic valve surgery. [less ▲]

Current theories on the evolution of paedomorphosis suppose that several ontogenetic pathways have appeared according to different selective pressures. The aim of this study was to find out whether two distinct processes can lead to paedomorphosis in the Alpine newt, Triturus alpestris. In this respect, we compared age structures of paedomorphic and metamorphic individuals in two newt populations where the two forms lived syntopically. Whereas paedomorphosis resulted in a slower rate of somatic development in one population, it resulted in an acceleration of sexual maturation in the other population. These processes correspond to neoteny and progenesis, respectively. These results suggest that phenotypic plasticity can result from contrasted ontogenetic pathways between two populations of the same species. They give support to models that consider gonadic development as the target of selection under different environmental pressures. [less ▲]
