Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Plaguicidas, impacto en salud y medio ambiente en sinaloa (méxico): implicaciones y retos en gobernanza ambiental

open access: yesTrayectorias Humanas Trascontinentales, 2019
El uso de plaguicidas en el sector agrícola sinaloense es una de las prácticas más comunes en la actividad primaria de la región. La exposición a éstos representa un factor definitivo, a la vez para la salud ambiental y la de la sociedad, en este caso la

Echanges thermiques des parois d’un environnement habitable: étude et analyse

open access: yesRevue des Énergies Renouvelables, 2018
Ce modeste travail porte sur l’étude des différents modes de transferts énergétiques entre l’environnement habitable et l’atmosphère. Il s’agit d’échanges d’énergie et de masse qui s’opèrent entre les deux systèmes et qui impliquent donc leur ...

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Interdiction de l’exploitation minière en Antarctique, une réalité menacée ?

open access: yesNatures Sciences Sociétés, 2018
Plus de vingt-cinq ans ont passé depuis l’adoption du protocole au traité sur l’Antarctique relatif à la protection de l’environnement (signé à Madrid en 1991) qui consacre l’interdiction des activités relatives aux ressources minérales, sauf à des fins ...

Validating antler‐ and movement‐based estimates of caribou reproduction using video camera collars Validation des estimations de la reproduction du caribou basées sur la rétention des bois et  sur le déplacement à l'aide de colliers‐caméras

open access: yesThe Journal of Wildlife Management, EarlyView.
We used GPS video camera collar data from barren‐ground caribou in the Porcupine and Western Arctic herds to validate antler‐ and movement‐based methods for estimating annual reproductive metrics. Antler retention was highly accurate for estimating parturition, but the movement methods we tested performed marginally for estimating parturition and ...

Hunting Strategies and Game Exploitation Organization in the Magdalenian: An Integrated Approach Based on Mortality Profiles and Stable Isotopes at Chaves Cave (Huesca, Spain)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Understanding hunting strategies in Upper Paleolithic contexts remains challenging due to the complex relationships between prey behavior, environmental conditions, and human decision‐making. Addressing these dynamics requires integrating archeozoological, geospatial, and geochemical proxies capable of capturing demographic patterns, landscape

Home and away: allometry and climate drive morphology of European rabbits in their native and introduced range

open access: yesOikos, EarlyView.
Climatic conditions shape phenotypic evolution by driving adaptations that optimise organismal function. Invasive species provide valuable systems to study these processes, as they often encounter novel climatic conditions in their introduced ranges. The European rabbit Oryctolagus cuniculus, native to the Iberian Peninsula, has established populations
