How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

L’incertitude persiste au sujet de l’efficacité des prélèvements létaux de loup à réduire la prédation de cette espèce sur les troupeaux domestiques, que cela soit en France ou ailleurs où ces mesures sont appliquées. Dans cet article, nous résumons les résultats de la thèse d'Oksana Grente réalisée sous la direction de l’Office Français de la Biod...
Persistence of viable populations may be uncertain for large carnivore species, especially for those established in human-dominated landscapes. Here, we studied the Eurasian lynx in Western Europe established in the Upper Rhine metapopulation (i.e., Jura, Vosges-Palatinian and Black Forest populations) and in the Alpine population. These population...
Les Journées ITTECOP se sont tenues les 25 et 26 mars 2021 en distanciel. Elles ont été l'occasion de présenter les résultats des projets issus de l'APR 2017 et les nouvelles recherches de l'APR 2020. Organisées autour de six sessions, une large place a été offerte aux échanges entre chercheurs et acteurs opérationnels.
The occurrence of wolf populations in human-dominated landscapes is challenging worldwide because of conflicts with human activities. Modeling is an important tool to project wolf dynamics and expansion, and help in decision making concerning management and conservation. However, some individual behaviors and pack dynamics of the wolf life cycle ar...
En France, la protection des troupeaux contre les attaques de loup prévoit l’utilisation de tirs dérogatoires dans des contextes précis, notamment lorsque la pression des attaques est forte. Néanmoins, les effets de ces tirs sur les attaques restent mal connus. Nous dressons ici un état des connaissances scientifiques sur le sujet puis présentons l...
Land-use change and climate change are recognized as two main drivers of the current biodiversity decline. Protected areas help safeguard the landscape from additional anthropo-genic disturbances and, when properly designed, can help species cope with climate change impacts. When designed to protect the regional biodiversity rather than to conserve...

NetLogoR is an R package to build and run spatially explicit agent‐based models (SE‐ABMs) using the R language. SE‐ABMs are models that simulate the fate of entities at the individual level within a spatial context and where patterns emerge at the population level. NetLogoR follows the same framework as the NetLogo software (Wilensky 1999). Rather...
Future human land use and climate change may disrupt movement behaviors of terrestrial animals, thereby altering the ability of individuals to move across a landscape. Some of the expected changes result from processes whose effects will be difficult to alter, such as global climate change. We present a novel framework in which we use models to (1)...
Large carnivores are wide-ranging species, highly mobile and live in human-dominated landscapes where habitat destruction and fragmentation are important threats. In parallel, the terrestrial transportation network is getting denser and acts as a barrier for the movement of these animals as well as it increases the risk of collisions. The Eurasian...

Spatially explicit individual-based models (SE-IBMs) can simulate species’ movement behaviors. Although such models allow many applications to ecology and conservation biology and are useful for management purposes, they are difficult to parameterize directly from the kinds of observational data that are generally available. Coupled with pattern-or...
Collisions between wildlife and vehicles represent a large source of mortality for many species. To implement effective protection zones, it is important to identify areas in which wildlife–vehicle collisions are likely to occur. We used statistical models to derive an index of risk of co-occurrence between manatees and boats. Our statistical model...
Extensive niche overlap between closely related species generally leads to aggressive interactions and competition. The short-tailed mouse (Mus spretus Lataste, 1883) and the wood mouse (Apodemus sylvaticus (L., 1758)) show a large habitat overlap without aggressive interactions. The present study investigates the existence of food competition betw...
In collaboration with several institutions (Sapienza University of Rome, Italy, Centre d'Ecologie Fonctionnelle et Evolutive, France, Superior Institute for Environmental Research and Protection,Italy and the Appennino Tosco Emiliano National Park, Italy) I produced a capture recapture model to estimate the relative abundance of admixed individuals in widlife populations. I then applied it to the genetic capture-recapture data on wolf x dog hybridization collected in the framework of the Life-EU project M.I.R.CO (LIFE13 NAT/IT/000728). I am currently working on the production of a popoulation projection model that will help understanding the impact of hybridization on the viability of wolf populations and identifying management solutions. This work is part of my PhD project, conducted in joint supervision at Sapienza University of Rome and University of Montpellier.
In this project, we focuse on the Eurasian lynx (Lynx lynx) and its populations in the Vosges and Jura mountains in France and Switzerland. Our main objective is to develop and provide an operational tool upon which the managers would rely on in the decision-making process for land-use planning.
