Impacts of ocean warming, acidification and food quality on European abalone growth and reproduction: A Dynamic Energy Budget model approach across climate scenarios

Ocean acidification and warming (OAW) are expected to alter physiology, growth and reproduction of marine ectotherms, yet their combined effects on life-history traits remain unresolved, particularly under poorly defined future food conditions. Using a Dynamic Energy Budget (DEB)...

Integrative metabarcoding reveals Trypanosoma cruzi infection, blood-feeding sources, and gut microbiota in the peridomestic vector Triatoma costalimai

The protozoan parasite Trypanosoma cruzi , the etiological agent of Chagas disease, has a complex cycle involving interactions with triatomine vectors and a variety of vertebrate hosts across sylvatic, peridomestic, and domestic niches. Triatoma costalimai (Hemiptera: Reduviidae)...

Barriers to Addressing Biodiversity Conservation in Multinational Companies and Strategies to Overcome Them

ABSTRACT Corporate initiatives supporting biodiversity conservation in multinational companies (MNCs) face limited commitment despite biodiversity's multiple benefits. Although reasons associated with MNCs' commitment are documented and include increased profits, stakeholder pres...

Morphological variation in Middle-Late Pleistocene stone points: a pan-African perspective

Stone points are central to defining the African Middle Stone Age (MSA), yet their morphological variability has rarely been quantitatively examined at a continental scale. Longstanding distinctions between ‘specific’ industries (e.g., Aterian, Still Bay, Howiesons Poort) and mor...

Environmental Gradients and Turnover Shape Aquatic Invertebrate Communities in High‐Andean Ecosystems of Northern Chile

ABSTRACT The high Andean salars of northern Chile are unique ecosystems characterised by their high altitude (up to > 4000 m above sea level), high salinity and marked geographical isolation. Despite their ecological importance and increasing exposure to anthropogenic pressures s...

Rearrangement of chromosome spatial organization in mouse zygotes using optical tweezers does not affect preimplantation development

The spatial arrangement of chromosomes is thought to influence key processes such as gene expression or chromosome segregation. However, the contribution of chromosome spatial organization in physiological contexts remains disputed. Here, we use optical tweezers to displace nucle...

Urban-to-downwind variations in aerosol composition and optical properties in the Paris urban plume from coordinated airborne and ground-based observations

Abstract. Aerosols play a critical role in Earth’s climate, but substantial evolution in their physicochemical properties after emission introduces uncertainties in predicting their climate impacts. Observational constraints on how aging modifies aerosol properties remain limited...

Ontogenetic allometry of the first gonopod in the land crab Johngarthia lagostoma (H. Milne Edwards, 1837) (Crustacea: Brachyura: Gecarcinidae): delayed development of the corneous unguis suggests morphofunctional specialization

Abstract In Brachyura, reproduction involves a range of behavioral, morphological, and physiological mechanisms that contribute to reproductive success. The land crab Johngarthia lagostoma , endemic to four oceanic islands in the South Atlantic, shows no clear pre- or post-copula...

Global origins of tuna and billfish fisheries reveal the transition from coastal access to oceanic exploitation

Ocean ecosystems have played a crucial role in people’s lives around the world for millennia. However, questions persist about when, why, and how people first began removing biomass from offshore habitats and established fisheries in distant, oceanic environments. We explore the...

New species from the cradle of biodiversity inventories: cryptic diversity within Lamellariinae in the European Atlantic and Mediterranean (Gastropoda: Velutinidae)

The Mediterranean, despite a long tradition of naturalist observation dating back to Aristotle, is still home to undisclosed cryptic species complexes. The gastropod subfamily Lamellariinae d’Orbigny, 1841 (Velutinidae Gray, 1840) is composed of benthic sea slug-like species with...

Impact of a High‐Fiber, Fruitless Diet on the Gut Microbiome, and Health of Captive Orangutans

ABSTRACT Diet is a crucial factor in modulating the gut microbiome, and understanding these interactions in captive primates is essential for their health and welfare. This study assessed the impact of the transition to a high‐fiber, low‐sugar diet on the gut microbiome, behavior...

Revisiting Alpinia cumingii (Zingiberaceae): phylogenetic placement, recircumscription and a description of a new morphologically similar species

Alpinia cumingii was described by Karl Moritz Schumann from the Philippines in 1904. Two remarkably similar species, also from the Philippines, Alpinia penduliflora and Alpinia pendula, were described respectively in 1909 by Henry Nicholas Ridley and 1928 by Eduardo Quisumbing an...

Deep learning reveals ecological decoupling and rate heterogeneity in Hymenoptera wing evolution

Quantifying biomorphological evolution and integrating phenotypic data into large-scale ecological and evolutionary studies are often limited by the scalability, subjectivity, and poor interpretability of existing methods. We introduce HAIKA (Hierarchical Attention-based Interpre...

France’s Pesticide Load Index: Decreasing Ecotoxicity, Persistent Human Toxicity, Rising Concern For Environmental Fate

Pesticide use has strong adverse effect on biodiversity, ecosystem functioning and human health . Numerous policies have been proposed to reduce their use and associated risk but evaluations of changes in pesticide risk over time and space are still rare. Here, we evaluate tempor...

Bony labyrinth taxonomic identification and long-term evolution of livestock in the Southwest and Central Asia

Abstract Southwest and Central Asia were pivotal regions for the domestication and dispersal of domestic herbivores. Here we investigate long-term variation in bony labyrinth morphology of domestic bovids (sheep, goats and cattle) across the last 10 000 years. We focused on the o...

Soft-Templated Carbon Models Elucidate the Anomalous Increase of Capacitance in Nanopores

Abstract Supercapacitors are electrochemical energy-storage devices distinguished by rapid charge–discharge and high power density. The observation of anomalously enhanced capacitance in nanoporous carbons challenged classical descriptions of double-layer charging and stimulated...

Overcoming Sampling Limitations Using Machine-Learned Interatomic Potentials: The Case of Water-in-Salt Electrolytes

Abstract Machine-learned interatomic potentials hold the promise to enable the modeling of highly concentrated liquids over meaningful time scales, far from reach for current ab initio electronic structure methods. Here we evaluate the performances of various MACE potentials in m...

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example. Curren...

Buried in the pantry: using archaeoentomology to assess cave reuse at the pre-Hispanic site of Cruz de la Esquina

Entomology, the study of insects, is an integral part of modern forensic science and can also make substantial contributions in archaeology. Here, the authors report on archaeoentomological analyses conducted within the Cruz de la Esquina funerary cave (Acusa Seca, Gran Canaria,...

Settlement and Landscape Transformations in the Khaybar Oasis From Late Antiquity to the Late Islamic Period

ABSTRACT Archaeological survey and targeted soundings by the Khaybar Longue Durée Archaeological Project ( Khaybar LDAP ) have provided the opportunity to reconstruct a first overview of settlement dynamics, land use and socioeconomic organisation from the late pre‐Islamic period...
