Validating graph‐based connectivity models with independent presence–absence and genetic data sets

open access: yesConservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract Habitat connectivity is a key objective of current conservation policies and is commonly modeled by landscape graphs (i.e., sets of habitat patches [nodes] connected by potential dispersal paths [links]). These graphs are often built based on expert opinion or species distribution models (SDMs) and therefore lack empirical validation from data

DNA metabarcoding suggests adaptive seasonal variation of individual trophic traits in a critically endangered fish

open access: yesMolecular Ecology, Volume 31, Issue 22, Page 5889-5908, November 2022., 2022
Abstract Dietary studies are critical for understanding foraging strategies and have important applications in conservation and habitat management. We applied a robust metabarcoding protocol to characterize the diet of the critically endangered freshwater fish Zingel asper (the Rhone streber).

Growth variation in the endangered fish Zingel asper: Contribution of substrate quality, hydraulics, prey abundance, and water temperature

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 7, Page 1156-1170, July 2022., 2022
Abstract Intraspecific variation in life histories and its environmental correlates can indicate the degree of vulnerability to extinction of endangered taxa and guide conservation actions. Zingel asper (Percidae) is an endangered fish endemic to the Rhône catchment (France and Switzerland), where five populations subsist in separate river systems ...

Disentangling the components of coastal fish biodiversity in southern Brittany by applying an environmental DNA approach

open access: yesEnvironmental DNA, Volume 4, Issue 4, Page 920-939, July 2022., 2022
By filtering surface marine water and using eDNA we assessed fish biodiversity along the coast of southern Brittany (Iroise Sea). For Actinopterygii and Elasmobranchii taxa, we documented three complementary biodiversity components ‐ taxonomic, phylogenetic and functional diversity ‐ and three diversity facets ‐ richness, divergence and regularity.

Favoring recruitment as a conservation strategy to improve the resilience of long‐lived reptile populations: Insights from a population viability analysis

open access: yesEcology and Evolution, Volume 11, Issue 19, Page 13068-13080, October 2021., 2021
In long‐lived species, under normal conditions, adult survival is fairly high and constant, whereas less canalized demographic traits (e.g. the recruitment rate) vary over time and drive population trajectories. We used a long‐term set of capture–recapture data collected on a population of the critically endangered Lesser Antillean iguana, and show ...

Trophic niche overlap between sympatric harbour seals (Phoca vitulina) and grey seals (Halichoerus grypus) at the southern limit of their European range (Eastern English Channel)

open access: yesEcology and Evolution, Volume 11, Issue 15, Page 10004-10025, August 2021., 2021
There is a critical need for a better understanding of interactions between two sympatric seal species, the harbour and grey seals, considered as potential competitors. We identified here the overlap in trophic niches between these two species at the southern limit of their European range, in the Baie de Somme (Eastern English Channel, France).

Approches biogéographiques de la nature en ville : parcs, espaces verts et friches. [PDF]

open access: yes, 2000
Au cours des dernières années, le thème de la nature en ville a suscité beaucoup d'intérêt dans la littérature scientifique, notamment en ce qui a trait à la végétation des milieux urbains, et en particulier à la végétation qui colonise les espaces ...

Gestion durable du paysage : les leçons que les nouveaux parcs naturels régionaux doivent tirer de l'expérience des anciennes corporations [PDF]

open access: yes, 2007
The landscape is increasingly perceived as a resource. For this reason, it is necessary to find legal, political and economic instruments that will succeed in managing this “resource landscape” in the long term.

Valorisation des aménités et développement territorial : le rôle des Parcs Naturels Régionaux

open access: yesVertigO, 2015
Two complementary approaches were used to show the potential links between environmental amenities, territorial rent and the development process. The first approach is experimental and multidisciplinary and associates the fields of ecology, cognitive ...

Domaines « vides » et structuration morphologique de l’agglomération montréalaise [PDF]

open access: yes, 1997
L'avenir de l'agglomération montréalaise inquiète. Plusieurs s'en préoccupent. Mais s'interroge-t-on suffisamment sur le fait que la recherche de solutions a rarement suscité une remise en question de la manière dont le problème est posé depuis près de ...
