Marécages, une pollution par essence? Conditions d'une écopoétique des marais et autres zones humides au XXe siècle

open access: yesOrbis Litterarum, Volume 81, Issue 3, Page 271-280, June 2026.
Abstract To expose the pollution of marshes and swamps, whether by hydrocarbons or other contaminants, the French or Francophone author of the twentieth century must first confront a literary tradition that equates stagnant water with a volatile poison and, more broadly, wetlands with toxic environments. In his article “Wetland Gloom and Wetland Glory,”

Oviposition, flight and walking capacity at low temperatures of four aphid parasitoid species (Hymenoptera: Aphidiinae)

open access: yesEuropean Journal of Entomology, 2004
Precocious activity of parasitoids is a key factor for cereal aphid control. We investigated the oviposition, flight and walking capacities at low temperature of four aphid parasitoids (Aphidius rhopalosiphi, A. ervi, Praon volucre, P.

Orchids in the Open: Understanding Biodiversity Beyond Madagascar's Forests

open access: yesDiversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Orchids make up 8% of Madagascar's vascular plant species richness and are typically associated with the island's forests. Yet most of the island is covered by open ecosystems, long dismissed as degraded. This perception has contributed to their neglect, limiting our understanding of species ecology and hindering conservation action in ...

Les milieux naturels et le sacré. Esquisse d’une biogéographie spirituelle de la nature

open access: yesBulletin de l’Association de Géographes Français, 2019
By combining individual or collective sacred experiences with the natural objects that create them, the aim was to draw up a phenomenological classification in which environmental forms are not only perceived as objective realities, but also as symbolic ...

Colour polymorphism and conspicuousness do not increase speciation rates in Lacertids

open access: yesPeer Community Journal, 2023
Conspicuous body colours and colour polymorphism have been hypothesized to increase rates of speciation. Conspicuous colours are evolutionary labile, and often involved in intraspecific sexual signalling and thus may provide a raw material from which ...

Evolutionary history and interspecific gene flow in six Coenonympha butterfly species in Europe Histoire évolutive et flux de gène entre six espèces de papillons du genre Coenonympha en Europe

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 72-83, January 2026.
We analysed genomic data from six closely related Coenonympha butterflies to explore their diversification history across Europe. Despite widespread secondary gene flow, the six species remain genetically distinct, even in areas where their distribution ranges overlap.

Phylogenomics of Messor harvester ants (Hymenoptera: Formicidae: Stenammini) unravels their biogeographical origin and diversification patterns La phylogénomique des fourmis moissonneuses Messor (Hymenoptera: Formicidae: Stenammini) clarifie leur origine biogéographique et leurs patrons de diversification

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 1025-1040, October 2025.
Phylogenomic analysis of 2524 ultraconserved‐element loci from 58 Messor harvester ant species helps in redefining taxonomic groups of the genus. Messor ants emerged in the Irano‐Indian area around 20 million years ago, rapidly dispersing to the Western Palaearctic and Northeastern Africa during the early Miocene.
