Introduction
My PhD is about peatbog dynamics, studied through arthropods (spider, ants and ground beetle) and vegetation diversity. Those diversities are assessed both for actual and past diversities with arthropod trapping and active sampling coupled with botanical relevé and paleoecological method. The sampling take place in the peatbogs of the french archipelago in north america of Saint-Pierre and Miquelon and in the Nain archipelago in Labrador (Canada).

In the internet era, the digital architecture that keeps us connected and informed may also amplify the spread of misinformation. This problem is gaining global attention, as evidence accumulates that misinformation may interfere with democratic processes and undermine collective responses to environmental and health crises. In an increasingly poll...

Mass media plays an important role in the construction and circulation of risk perception associated with animals. Widely feared groups such as spiders frequently end up in the spotlight of traditional and social media. We compiled an expert-curated global database on the online newspaper coverage of human-spider encounters over the past ten years...

Aim Species distribution models (SDMs) have emerged as essential tools in the equipment of many ecologists, useful to explore species distributions in space and time and answering an assortment of questions related to biogeography, climate change biology and conservation biology. Historically, most SDM research concentrated on well‐known organisms,...

Although functional and phylogenetic diversities are increasingly used in ecology for a variety of purposes, their relationship remains unclear, and this relationship likely differs among taxa, yet most recent studies focused on plants. We hypothesize that communities may be diverse in functional traits due to presence of: many phylogenetic lineage...

Les zones humides ont été fortement modifiées et dégradées du fait de l’extension de l’urbanisation, des infrastructures linéaires et de l’intensification des pratiques agricoles. Leur restauration présente l’opportunité de reconquérir les fonctions de régulation quantitative et qualitative de l’eau qui y sont liées mais aussi un gain en termes de...

Whereas bait and pitfall trappings are two of the most commonly used techniques for sampling ant assemblages, they have not been properly compared in temperate open habitats. In this study, taking advantage of a large-scale project of heathland restoration (three sites along the French Atlantic Coast forming a north-south gradient), we evaluated th...

Although functional and phylogenetic diversities are increasingly used in ecology for a large variety of purposes, their relationships remain unclear and likely vary presumably over taxa, yet most recent studies focused on plant communities. Different concepts predict that a community becomes functionally more diverse by adding phylogenetic lineage...

Anergates atratulus (Schenck, 1852), recently known as Tetramorium atratulum (WARD et al. 2015) is a permanent social parasite of another ant that belongs to the taxon Tetramorium caespitum-impurum. This species is considered localized and even rare in Europe. It was discovered by capture in 2017 on a moorland at the western of the island of Belle-...

Assessment of habitat restoration often rely on single-taxa approach, plants being widely used. Arthropods might yet complement such evaluation, especially in hard, poorly-diversified environments such as maritime clifftops. In this study we compared the responses of spiders and plants (both at species and assemblage levels) to increasing time of h...
