Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Trophic niche comparison of three mustelids in southwestern France

open access: yes, 2019
The European mink, Mustela lutreola, is the most threatened carnivore in the world particulary in France. He lives only in the southwestern departements: Pyrénées-Atlantiques, Landes, Gironde, Lot-et-Garonne, Dordogne, Charente and Charente-Maritime. The causes of the decline in mink populations were addressed in a multidisciplinary manner with food ...

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

open access: yesBrain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Representativeness of the Natura 2000 network for preserving plant biodiversity in the European Union

open access: yesConservation Biology, EarlyView.
Abstract The Natura 2000 (N2K) network of protected areas is one of the main tools for area‐based conservation in the European Union (EU), yet its role in preserving plant biodiversity requires better understanding. We examined data kept in the European Vegetation Archive from over 1.2 million vegetation plots and obtained over 14.2 million plant ...

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

open access: yesConservation Biology, EarlyView.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

open access: yesConservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.
