Graphab

2011

L’objectif du projet Graphab est de proposer et tester un ensemble de méthodes permettant d’estimer l’impact des grandes infrastructures de transport sur la distribution des espèces. Cette démarche part du constat que les études d’impact classiques sont limitées à une zone proche du tracé des infrastructures alors qu’un effet de barrière peut se produire à plus longue portée, si les espèces sont fortement dépendantes de leur réseau écologique. L’approche choisie pour modéliser les réseaux écologiques est celle des graphes paysagers, qui ont été couplés à des modèles de distribution d’espèces. En comparant les résultats de modèles de distribution de façon diachronique, avant et après la mise…

Assessing habitat connectivity of the lesser horseshoe bat using graph theory to explain its distribution

2011

The lesser horseshoe bat, Rhinolophus hipposideros was formerly widespread and quite common in north-western Europe, but has undergone a dramatic decline from the 1960s. The main hypothesis for this decline is a change of habitat quality. Recent works have stressed the importance of good connection between roosts and foraging areas by tree lines and well-structured hedgerows. Thus, landscape connectivity is assumed to be a key-factor for population sustainability. The present study is based on a case study in Franche-Comté (France). Its purpose is to model the distribution of the lesser horseshoe bat and to characterize the functional connectivity of its habitat. Graph theory is used effici…

Graphab 2

2015

For some ten years, landscape graphs have been widely used for modeling ecological networks and measuring landscape connectivity from an operational perspective. A landscape graph is a set of nodes (habitat patches for a given species or group species) potentially connected by links representing the functional connectivity between each pair of nodes. With their simple design and their ecological relevance, graph-based methods can serve as a guide for planning decision-making, especially for the conservation of ecological networks. In this perspective, Graphab 2 project aims to use landscape graphs to assess the impact of transport infrastructures on the functionality of ecological networks,…
