Six-fold reduction in ocean heat content estimate uncertainty since 1960

Abstract Ocean heat content (OHC) dominates Earth’s energy imbalance, but its uncertainty has not been fully understood. Here, we construct a Large-Ensemble to comprehensively quantify the OHC uncertainty from global to regional scales since 1955, and consider eight groups of err...

Grid4Earth: An Open-Source Python Ecosystem for Geospatial Data Integration Using an Ellipsoidal HEALPix DGGS

Abstract. The rapid growth in Earth observation (EO) and Digital Twin Earth data volumes creates a need for global, reproducible, and cloudnative spatial representations. Conventional latitude–longitude grids and projected tiling systems remain useful, but they introduce projecti...

Local Trade‐Offs Shape Flower Size Evolution Across Arabidopsis thaliana Distribution

The remarkable variation in floral form and size is thought to have driven the evolutionary radiation of angiosperms and has traditionally been attributed to pollinator-mediated selection on floral displays, yet emerging evidence indicates that abiotic environmental factors can a...

Environmental drivers of litter- and soil-dwelling springtail communities across European forests, assessed by morphotaxonomy and soil DNA metabarcoding

Springtails are abundant in forest litter and soils, where they play a crucial role in the transformation and decomposition of organic matter. However, most data on springtail communities originates from studies at the local and regional levels, while larger-scale studies are lac...

Addressing anthropogenic noise and electrical anisotropy hints in magnetotelluric data from the Annecy area (French Pre-Alps)

The magnetotelluric (MT) method is a widely used tool for geothermal reservoir exploration due to its capability of imaging fluids in the Earth’s crust. However, in urbanised environments, its application is often challenged by anthropogenic noise and low signal-to-noise ratios....

A 45-year high-resolution wave hindcast for the Fijian archipelago: mean climate, spectral characteristics, and long-term trends

Fiji’s coastal communities are highly exposed to ocean waves that drive erosion, inundation and shoreline change. Yet the Fijian archipelago lacks a comprehensive, wave-climate assessment at a resolution that represents island effects appropriately. To address this gap, we presen...

ViroSeek: a viral detection pipeline for second-generation sequencing

Abstract Arbovirus emergences represent a rising public health issue and are exacerbated by climate change and globalization. Virome analysis has become a key approach for monitoring and managing infectious diseases, yet existing tools often remain technically complex and inacces...

Urbanisation and habitat loss favour thermophilic and monogynous ant species

Environmental changes such as urbanisation and related habitat loss and fragmentation profoundly impact ecological communities by altering habitats, resources, and microclimates. Yet, the impacts of the resulting environmental conditions on metacommunity dynamics, ranging from sp...

Anticancer and Cardioprotective Properties of Medicinal Mushrooms: Current Evidence and Future Prospects

Introduction: Cardiotoxicity is an undesirable side effect of chemotherapy that limits the effectiveness of cancer treatment. Almost all cardiotoxic agents cause cardiovascular complications, leading to oxidative stress and other pathological conditions. The search for bioactive...

Impact of extreme rainfall on triggering conditions and susceptibility for shallow landslides: a case study in the Alpes-Maritimes region (France)

Abstract. Prediction of shallow landslides at the regional scale generally relies on statistical analyses of landslide inventories. Rainfall-duration thresholds and susceptibility maps are among the most common approaches to anticipate future landslide occurrences. However, the o...

Potential glacier contributions to the 2024 La Bérarde flood

Abstract. On 20–21 June 2024, an unprecedented flood of the Etançons river caused important damage to the village of La Bérarde (Écrins, France). An analysis of the event showed that the flood was caused by the combination of an intense rain-on-snow event at high altitude and the...

Identification of living (Rose Bengal)-stained benthic foraminifera using automated image recognition

Abstract. Living and fossil benthic foraminifera are widely used as bioindicators of ecosystem quality, but their analysis is time-consuming. With the help of artificial intelligence, models for the automatic identification of fossil planktonic foraminifera and, more recently, be...

Coffea Comparative Genomics Reveals Subgenome-Associated Expansion and Diversification of Biosynthetic Gene Clusters

Biosynthetic gene clusters (BGCs) are important for plant specialized metabolism, but remain poorly characterized in coffee. Given Brazil’s importance in coffee production, we performed a comparative genomic analysis of BGCs across the allotetraploid Coffea arabica and its diploi...

Forgotten reservoirs: an attempt to revive field research on rodent malaria parasites in their main natural host, the thicket rat Grammomys poensis (formerly Thamnomys rutilans)

<title>Abstract</title> Rodent malaria parasites have long served as essential experimental models for understanding human malaria, yet little is known about their ecology and evolution in the wild. The thicket rat <italic>Grammomys poensis</italic> (formerly <italic>Thamnomys ru...

Rocks out, waste in: A double penalty in gravel-rich river valleys?

Construction and Demolition (C&D) waste is the largest solid waste stream in France, yet circular economy (CE) research on this sector tends to privilege technical and quantitative framings over its socio-economic and governance dimensions. This article examines the implementatio...

Sensitivity of the Bootstrap sea ice concentration algorithm to surface parameters in the Antarctic marginal ice zone using passive microwave retrievals

Abstract. Changes in sea ice concentration (SIC) and derived sea ice extent have been monitored using microwave radiometers since the late 1970s, providing information about the polar response to climate change, making SIC an invaluable variable for numerical models. Antarctic se...

Hematological profiles and preventive-practice characteristics among patients with podoconiosis: A case-control study in Musanze District, Rwanda

Background Podoconiosis is a chronic, disfiguring, non-filarial form of lymphedema caused by prolonged barefoot exposure to irritant soil. An estimated four million people are affected globally, with cases documented in more than 32 countries, 18 of which are in Africa. In Rwanda...

Health and nutrition returns to clean cooking fuel access across the rural-urban divide

Access to clean cooking fuels is central to advancing health, equity, and environmental sustainability worldwide. However, despite sustained policy efforts, a substantial share of households, especially in developing countries, still rely on polluting fuels, with adverse effects...

Widespread thermophilization but weak link to climate warming in Europe’s summit plant communities

Abstract Recent changes in alpine vegetation are often attributed to climate warming, particularly community composition shifts towards more warmth-associated species, or thermophilization. Here we assess the link between thermophilization and warming across 53 European mountain...

Policy Consequentiality in Tourism Discrete Choice Experiments

Stated preference methods are widely applied in tourism research, yet their validity depends on respondents perceiving surveys as policy consequential. This paper examines how such perceptions shape willingness-to-pay (WTP) estimates for redesigned tourism supply. Using a discret...
