Species distribution models (SDMs) are commonly used in ecology to map the probability of species occurrence on the basis of predictive factors describing the physical environment. We propose an improvement on SDMs by using graph methods to quantify landscape connectivity. After (1) mapping the habitat suitable for a given species, this approach consists in(More)
The aim of the present work is to assess the potential long-distance effect of a high-speed railway line on the distribution of the European tree frog (Hyla arborea) in eastern France by combining graph-based analysis and species distribution models. This combination is a way to integrate patch-level connectivity metrics on different scales into a(More)
Linear transportation infrastructures traverse and separate wildlife populations, potentially leading to their short- and long-term decline at local and regional scales. To attenuate such effects, we need wildlife crossings suitable for a wide range of species. We propose a method for identifying the best locations for wildlife crossings along linear(More)
Issues related to landscape changes and loss of biodiversity have emphasized the concept of ecological network. In its spatial meaning, an ecological network is a set of habitat patches linked by ecological fluxes. Since landscape graphs have recently appeared as efficient methods to model the ecological networks, the aim of this paper is to make a review(More)
