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

International 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

Patterns and environmental drivers of root traits across hydrological gradients in old growth boreal forests

Oikos, EarlyView.
Many key ecosystem functions are affected by plant roots and their traits. However, understanding of the patterns in, and drivers of, root traits lags far behind equivalent knowledge of above‐ground tissues, particularly in boreal old growth forests. We surveyed community‐level root traits across 11 old growth forests spanning a wide latitudinal range ...

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

Oikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

Polymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...

Informing the potential of mature temperate forests as natural climate solutions: Changed fine root biomass and morphology under elevated CO2

PLANTS, PEOPLE, PLANET, EarlyView.
The land carbon sink absorbs approximately 25% of anthropogenic CO2 emissions, with forests accounting for most. Managing forests as Natural Climate Solutions is therefore a societal imperative, requiring models of where and how long carbon resides within these ecosystems. We investigated the effects of elevated CO2 on fine roots, the primary source of

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.

Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

Responsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and
