SNR‐Efficient Inhomogeneous Magnetization Transfer (ihMT) for Clinical Applications at 7 T
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Inhomogeneous MT (ihMT) is an MRI modality sensitive to Myelin, the lipid‐rich membrane surrounding the axons. A novel ihMT saturation strategy and its associated B1+$$ {\mathrm{B}}_1^{+} $$ correction at UHF are proposed. The aim is to generate a strong ihMT effect within a clinically compatible scan time while complying with SAR ...

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns
Oikos, EarlyView.Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Elaborating more realistic model microplastics by simulating polypropylene's environmental ageing
Ecotoxicology and Environmental SafetyIn this work, we propose a new protocol for producing model microplastics from an industrial polymer and compare it to a conventional method, cryomilling.

Age ratio in groups of a social ungulate affects epizoochorous dispersal and diaspore exchanges
Oikos, EarlyView.Animal‐mediated seed dispersal is a key process in plant population dynamics, species distribution and ecosystem functioning. As long‐distance dispersal agents, ungulates help to maintain native plant populations facing abiotic changes in their habitat and habitat fragmentation or habitat loss.

Automated delineation and morphometry of unclassified subglacial bedforms
BoreasWe designed an automated tool to delineate and analyse the shape of subglacial bedforms using a recently defined land surface parameter, the volumetric obscurance.

Oikos, EarlyView.Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

Familiarity and aggression shape long‐term associations and mortality risk in a solitary ungulate
Oikos, EarlyView.Periodic social interactions are important to animal fitness, even in solitary species. For solitary species, these interactions can be unexpected and shaped by previous encounters. Despite being aggressive and largely solitary, black rhinoceroses Diceros bicornis are commonly seen in groups, suggesting they may engage in more social behaviours than ...

More than proteins for empty stomachs: Wild meat in the BaTonga food system
People and Nature, EarlyView.Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.
