The collective application of shorebird tracking data to conservation

open access: yesConservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

De la biologie à l’écologie

open access: yesArts et Savoirs, 2016
Les textes sur la nature des années 1850-1860 ont parfois accrédité la thèse d’un Michelet spiritualiste et d’une écologie-religion. Or, on peut se demander au contraire si Michelet ne projette pas de révolutionner les structures de l’imaginaire pour ...

Harnessing social media data to track species range shifts

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

Fonction de transfert pour l'estimation de la composition chimique des eaux fossiles à partir des diatomées. Calibration sur des lacs salés du Lipez, SW de l'Altiplano bolivien.

open access: yesCarnets de Géologie, 2002
L'étude des assemblages de diatomées et de la composition chimique des eaux a été effectuée dans 13 lacs salés peu profonds localisés dans le Sud de l'Altiplano Bolivien. Les points et les dates de prélèsvement sont les mêmes pour les deux types d'étude.

Genetic Diversity Impacts Climate-Induced Species Range Shifts. [PDF]

open access: yesEcol Lett
Genetic diversity may buffer species against climate‐driven range contractions and facilitate expansions, but its role at a global scale remains unclear. Using 4673 range shift estimates for 1888 species, we show that higher genetic diversity reduces trailing edge contractions under rapid warming and accelerates leading edge expansions under moderate ...

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, EarlyView.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Predicting soil water and mineral nitrogen contents with the STICS model for estimating nitrate leaching under agricultural fields [PDF]

open access: yes, 2012
The performance of the STICS soil-crop model for the dynamic prediction of soil water content (SWC) and soil mineral nitrogen (SMN) in the root zone (120 cm) of seven agricultural fields was evaluated using field measurements in a coarse-grained alluvial

Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

open access: yesJournal of Anatomy, EarlyView.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late
