Planification de la séquence « Éviter-Réduire-Compenser » à l’échelle du paysage : quel apport de la modélisation des réseaux écologiques à la mise en œuvre des sites naturels de compensation ? [PDF]

Sciences, Eaux & Territoires, 2022
Plusieurs équipes de chercheurs ont développé ces dernières années des cadres méthodologiques et des outils de modélisation spécifiques permettant de prendre en compte la dimension dynamique de la biodiversité dans les évaluations environnementales ...

Agostic Hydridoborate Complexes as Masked Coinage‐Metal Hydrides: Hydride Migration Between Boron and Gold Unlocks CO2 Reactivity

Angewandte Chemie International Edition, EarlyView.
Hydride addition to coinage‐metal diphosphine–borane complexes gives unprecedented Cu(I), Ag(I), and Au(I) hydridoborates featuring agostic σ(B–H)→M interactions. While, Cu and Ag derivatives are inert toward CO2, the Au analogue reversibly fixes CO2 and catalyzes its hydroboration as well as formic acid dehydrogenation through a cooperative B─H─Au ...

Dual‐Functional and Low‐Toxicity ZnO Nanoparticles From Pomegranate Peel: Impact of Synthesis Parameters on Photocatalytic and Supercapacitive Performance

ChemistryOpen
The development of eco‐efficient multifunctional nanomaterials is crucial for environmental remediation and energy storage. This study systematically investigated the impact of synthesis temperature (25°C vs. 80°C) and zinc acetate concentration (0.5–2 M)

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

The Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

Archaeology in Oceania, EarlyView.
ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils (Sarcophilus harrisii) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Pinikura country.

Distinct Molecular Pathways Supporting Sjögren Disease Clusters and Disease Progression

Arthritis &Rheumatology, EarlyView.
Objective Sjögren disease (SjD) is a heterogeneous autoimmune disease. We aimed to investigate blood transcriptomic signatures and disease progression among three recently defined clusters of patients with SjD: (1) B cell active disease with low symptom burden (BALS), (2) high systemic activity (HSA), and (3) low systemic activity with high symptom ...

La préservation de l’environnement au moyen du droit traditionnel. L’exemple des régions forestières de Côte d’Ivoire

Droit Public Comparé
En Côte d’Ivoire, et plus généralement en Afrique, le droit traditionnel à travers ses normes et institutions joue un rôle prépondérant dans la préservation de l’environnement. Elles sont très conservatrices et reflètent la place des différentes

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

Chemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.

Disentangling functional spaces: a multidimensional framework for ecology and conservation

Ecography, EarlyView.
Trait‐based ecology often relies on a single functional space, where diverse traits are combined into one multivariate framework. While convenient, this approach risks masking ecological strategies because variance is often dominated by a few traits, such as body size.
