Context Ecological networks (i.e. sets of connected natural habitats) emerged in the 1980s and have been implemented worldwide. They have been developed as a land-use planning tool that enables to ensure both habitat amount and landscape connectivity in response to ground based physical anthropogenic drivers (e.g. forest cuttings, roads, dams). Obj...

L’étude des effets des nuisances sonores sur la biodiversité progresse lentement mais sûrement. Dans la foulée d’autres trames écologiques, le concept émergent de « trame blanche » vise à identifier les zones d’un territoire où la pollution sonore doit être contenue ou réduite en priorité afin de permettre aux espèces d’accomplir la totalité de leu...

The growing concern about the negative impact of artificial light at night on biodiversity and human health increases the need of defining a general indicator that could be used for characterizing light pollution as well as performing both spatial and temporal comparisons. In this paper, we show that the traditional indicators based on direct numer...

Large-scale Transportation Infrastructures (LTIs) are among the main determinants of landscape fragmentation, with strong impacts on animal dispersal movements and metapopulation functioning. Although the detection of LTIs impacts is now facilitated by landscape genetic tools, studies are often conducted on a single species, although different spec...

Artificial light at night (ALAN) has been massively deployed worldwide and has become a major environmental pressure for biodiversity, especially contributing to habitat loss and landscape fragmentation. To mitigate these latter, green and blue infrastructure policies have been developed throughout the world based on the concept of ecological netwo...

Le livrable I du projet CIRFE est un résumé opérationnel des travaux conduits au sein du projet. Il reprend également les implications opérationnelles de ces travaux et constitue un outil d'aide à la décision concernant l'utilisation des outils de modélisation de dynamique de population et de connectivité dans la conduite d'études réglementaires.

Barrier effects of Large-scale Transportation Infrastructures (LTIs; roads, railways, etc.) are among the main factors contributing to the fragmentation of habitats. The reduction of dispersal across LTIs can drive small, local populations to extinction. The detection of barrier effects has been facilitate thanks to the development of the field o...

In the New Aquitaine region (southwestern part of France), Incidents (collisions and wanderings) with large mammals (roe deer, wild boars and deer) account for 30% of train incidents with animals. For security reasons, each collision necessitates the immobilization of the train for inspection, and therefore delays for the passengers and repairs and...

La protection des troupeaux domestiques est un enjeu important de la cohabitation des élevages avec le loup. Pour accompagner les éleveurs, la France a mis en place depuis 2004 un dispositif d’aide cofinancé par le FEADER. En vue de l’améliorer, une évaluation de son efficacité sur la période 2004‐2009 a été menée 2 . Les résultats indiquent que la...

Itraconazole is the most widely used treatment against Batrachochytrium dendrobatidis (Bd), the fungal pathogen causing chytridiomycosis, a proximate cause of amphibian declines. Several side effects of itraconazole treatment, ranging in severity from depigmentation to death have been reported in different amphibian species and life stages, and the...

SimOïko est un nouvel outil d’aide à la décision pour la gestion des espaces naturels. Il est particulièrement utile pour les phases de concertation et de planification.

The presentation presents the amphibian part of the CIRFE project consisting in a MRR survey coupled with a population genetics survey. First results of the MRR survey are presented in this presentation.

Consistency in behaviour is currently receiving a renewed interest. Although courtship display is generally consistent in terms of behavioural sequence and structure, there is also commonly important variation in the intensity of courtship display between and within males of a given species. Indeed, not all males have the same ability to perform co...

Infectious diseases are considered as a significant factor in the global decline of amphibians. In some vertebrates, the assessment of the individual sexual traits can be useful for assessment of their health status and immunocompetence due to trade-off between them and investment in the immune system. Our aim here was to determine whether the trade...

Dermocystid mesomycetozoan parasites and especially species from the genus Amphibiocystidium are known to infect several European amphibian species and one species (A. ranae) was associated with a recent decline of frogs in Italy. Nonetheless, the distribution of these parasites remains largely unknown, underlining an urgent need to document both t...

The literature is full of examples of inbreeding avoidance, while recent mathematical models predict that inbreeding tolerance or even inbreeding preference should be expected under several realistic conditions like e.g. polygyny. We investigated male and female mate preferences with respect to relatedness in the fruit fly D. melanogaster. Experime...

There is increasing evidence that female mate choice is often based on the assessment of multiple male traits, involving both morphology and behavior. We investigated female mate choice for multiple male traits in the palmate newt, Lissotriton helveticus, including male tail filament length, hind foot web size, crest development, body size, ventral...

Although size-assortative mating in convict cichlids, Amatitliana nigrofasciata, is supposed to result from mutual mating preference for larger individuals, female choice in relation to male size remains ambiguous. We revisited the evidence for directional preference for larger males in female convict cichlids using a classical two-way choice appar...
