Integrating target capture with whole genome sequencing of recent and natural history collections to explain the phylogeography of wild‐growing and cultivated cannabis

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1771-1788, November 2025.
Cannabis has been used by humans for millennia, resulting in diverse landraces and uses. Its complex legal status and economic importance make sampling wild‐growing populations difficult, limiting past studies to modern cultivars with low genetic diversity. Our research provides crucial insights into the genetic diversity of wild‐growing and cultivated

Genomics and morphometry of herbarium specimens elucidate the origin of the Cape Verde date palm (Phoenix atlantica A.Chev.) and highlight its agronomic potential

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1358-1371, September 2025.
As climate change accelerates, breeding resilient crops is urgent. The date palm (Phoenix dactylifera L.), a crucial 18 billion USD fruit crop, underpins North African and West Asian oasis agroecosystems. This study investigates the genetics and morphology of its closest wild relative, the endemic and endangered Cape Verde date palm (Phoenix atlantica ...

Gestion optimisée de la variabilité génétique dans les populations porcines sélectionnées

open access: yesINRAE Productions Animales, 2006
Il est possible de modérer l’accroissement des coefficients de parenté et de consanguinité dans les populations sélectionnées en calculant les taux optimaux d’utilisation des reproducteurs, compte tenu de la diversité génétique existante, et en ...

Paleogenomics: reconstruction of plant evolutionary trajectories from modern and ancient DNA

open access: yesGenome Biology, 2019
How contemporary plant genomes originated and evolved is a fascinating question. One approach uses reference genomes from extant species to reconstruct the sequence and structure of their common ancestors over deep timescales.

Valoriser et renforcer les mécanismes d’évolution génétique par la sylviculture, pour l’adaptation au changement climatique

open access: yesRevue Forestière Française, 2020
L’adaptation est un enjeu majeur de la gestion forestière dans le contexte du changement climatique La diversité génétique qui caractérise les arbres forestiers leur confère un potentiel adaptatif très important mais pas illimité Prendre en compte les ...

Tuta absoluta's population genetic structure across Africa: Two well‐delineated but weakly differentiated groups suggesting few introductions and significant gene flow Structure génétique des populations de Tuta absoluta à travers l'Afrique: deux groupes bien délimités mais faiblement différenciés suggérent peu d'introductions et un flux génétique important

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 2, Page 223-240, May 2025.
Abstract Describing the genetic structure and diversity of invasive insect pest populations is essential to better understand a species' invasion history and success throughout its distribution range. Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae) is a destructive pest of tomato and many other solanaceous crops, with very high economic impacts. Its

Impacts de croisement d’absorption sur l'élevage caprin dans le sud tunisien : cas de la délégation de Mareth

open access: yesJournal of Agriculture and Environment for International Development, 2012
L’importance particulière de la chèvre locale, en tant que ressource génétique indispensable pour la valorisation des parcours des régions arides, incite à déployer des efforts pour sa caractérisation et la mise au point de méthodologies de son ...

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) relating to an analysis of the health risks associated with exposure to caterpillars with stinging hairs and the development of management recommendations

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Several species of Lepidoptera with caterpillars bearing urticating hairs are increasing their range in metropolitan France from year to year, such as the pine processionary (Thaumetopoea pityocampa Denis et Schiffermüller 1775) whose presence was historically limited to the south of France, and which is gradually being observed in the north ...

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the assessment of the impact of fox population dynamics on public health

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
ABSTRACT The Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents.

Pollinator functional group abundance and floral heterogeneity in an agroecological context affect mating patterns in a self‐incompatible wild plant

open access: yesAmerican Journal of Botany, Volume 111, Issue 12, December 2024.
Using a farm‐scale experiment, we investigated how the mating outcomes (expected heterozygosity and paternity correlation) of Cyanus segetum in agroecological infrastructures (herbaceous field margins) are affected by the interplay between pollinator functional group abundance and, respectively, the relative maternal plant attractiveness and the local ...
