Monitoring and characterizing heterogeneous Mediterranean landscapes with continuous textural indices based on VHSR imag...
Remote sensing tools (RS) can contribute to a better understanding of the diversity of natural and semi-naturals habitats, their spatial distribution, and their conservation status. RS can also provide a generic set of derived indicators to support local to regional habitat monitoring. Here we propose a set of synthetic continuous textural indices ...
River Continuity Restoration and Diadromous Fishes: Much More than an Ecological Issue
...Published in Environmental Management
Ecosystem fragmentation is a serious threat to biodiversity and one of the main challenges in ecosystem restoration. River continuity restoration (RCR) has often targeted diadromous fishes, a group of species supporting strong cultural and economic values and especially sensitive to river fragmentation. Yet it has frequently produced mixed results ...
Zones Humides : des écosystèmes riches mais menacés
Les zones humides de la Nouvelle-Aquitaine constituent des écosystèmes très variés du point de vue morphologique et écologique. Cette richesse s'exprime également à travers la fourniture de nombreux services au territoire. Cependant, les dynamiques fonctionnelles des zones humides sont peu à peu menacées par le changement climatique, ce qui impliqu...
MARBEC-Obs : towards a virtual observatory of marine and coastal ecosystems, mainly in Mediterranean and tropical areas
Flow intermittence and ecosystem services in rivers of the Anthropocene
1. Intermittent rivers and ephemeral streams (IRES) are watercourses that cease flow at some point in time and space. Arguably Earth's most widespread type of flowing water, IRES are expanding where Anthropocenic climates grow drier and human demands for water escalate. 2. However, IRES have attracted far less research than perennial rivers and are...
A multimedia hydrological fate modelling framework to assess water consumption impacts in Life Cycle Assessment
Many new damage oriented methods have recently been developed to address environmental consequences of water consumption in life cycle assessment (LCA). However, such methods can only partially be compared and combined, since their modelling structure and metrics are inconsistent. Moreover, they focus on specific water sources (e.g. river) and miss...
Quelle stratégie de recherche pour une meilleure conservation de la biodiversité terrestre dans les îles tropicales ultr...
Les îles tropicales de l'Outre-mer français, réparties dans 11 territoires situés dans trois océans (Atlantique, Indien et Pacifique), concentrent, sur des superficies terrestres restreintes, une diversité d'espèces et d'habitats exceptionnelle. Ces îles comptent en effet plus de 70% des 17 947 espèces végétales et animales endémiques françaises co...
Functional redundancy and sensitivity of fish assemblages in European rivers, lakes and estuarine ecosystems
...Published in Scientific Reports
The impact of species loss on ecosystems functioning depends on the amount of trait similarity between species, i.e. functional redundancy, but it is also influenced by the order in which species are lost. Here we investigated redundancy and sensitivity patterns across fish assemblages in lakes, rivers and estuaries. Several scenarios of species ex...
Complementarity of two high-resolution spatiotemporal methods (hydroacoustics and acoustic telemetry) for assessing fish...
The complementarity of two high-resolution spatiotemporal acoustic methods, telemetry and hydroacoustics, was evaluated during the same time window to obtain fish distribution in a canyon-shaped reservoir, the Bariousses Reservoir (France). These methods act at an individual scale for telemetry and a community scale for hydroacoustics. The temporal...
