Since landscape connectivity reflects a basic form of interaction between species and their environment, the modelling of landscape networks is currently an important issue for researchers in ecology and practitioners of landscape management alike. Graph-based modelling has recently been shown to be a powerful way of representing and analysing landscape(More)
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)
Habitat restoration is one way of reducing landscape fragmentation, which is seen as a threat to biodiversity. It consists in renovating disused or degraded habitat patches or in creating new habitat patches in suitable areas. Currently, most restoration measures draw on the local knowledge of experts for selecting the best locations. For amphibian(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)
Land-cover changes (LCCs) could impact wildlife populations through gains or losses of natural habitats and changes in the landscape mosaic. To assess such impacts, we need to focus on landscape connectivity from a diachronic perspective. We propose a method for assessing the impact of LCCs on landscape connectivity through a multi-species approach based on(More)
The aesthetic potential of landscape has to be modelled to provide tools for land-use planning. This involves identifying landscape attributes and revealing individuals' landscape preferences. Landscape aesthetic judgments of individuals (n = 1420) were studied by means of a photo-based survey. A set of landscape visibility metrics was created to measure(More)
