Energy expenditure of bonobos across their locomotor repertoire

Unlike quadrupedal mammals, primates use diverse locomotor modes adapted to arboreal environments. Such diversity of movements challenges allometric models, which underestimate energetic costs by focusing on steady-state walking. To address this, we combined ethological and biome...

Photovoltaic panels affect arthropod and plant communities: a systematic review

Due to climate change, photovoltaic facilities are being rapidly scaled up. However, such a development can come at a cost for biodiversity. We conducted a systematic review, including a critical appraisal, and meta-analyses to better understand the effects of photovoltaic panels...

Zoological biobanks as a resource for microplastic analysis: a Py-GC-MS/MS case study on sea cucumbers

Microplastics have spread through every ecosystem studied. Yet, documenting their spatiotemporal distribution remains challenging, particularly in marine environments where sampling is costly and difficult. Archived specimens in zoological biobanks offer an underused resource for...

Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Abstract Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ 56 Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust from French Gu...

Investigating a Devonian vertebrate assemblage with synchrotron microtomography of coprolites

Abstract Fossilised faeces (coprolites) are a unique source of information as they record palaeontological evidence of animal behaviour (autecology) as well as interactions between extinct organisms and their environment (synecology). Four samples bearing coprolites found in a ne...
