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...

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...

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...

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...

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...

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...

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...

Will work for sardines: 20 years of animal-borne ocean observing by Australia’s Integrated Marine Observing System (IMOS) Animal Tagging Facility

The world’s ocean stores ~90% of the excess heat generated by anthropogenic global warming, making sustained ocean observations essential for understanding physical, biological and climate processes. Here, we describe how the Integrated Marine Observing System (IMOS) Animal Taggi...

Questioning the Evidence for Host-Symbiont Codiversification in Mycorrhizal Symbioses

Abstract The vast majority of plants form mycorrhizal symbioses. The ecological importance of these mutualistic interactions has sparked interest in their long evolutionary history. By examining interaction networks and phylogenetic trees, several studies have suggested that plan...

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...

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...

Genetic variability and population structure within the Anopheles tessellatus complex (Theobald, 1901) in Indonesia using ITS2 nuclear and COI, COII mitochondrial sequences

Abstract Some Anopheles species that act as malaria vectors are members of species complexes, a concept whereby sibling species cannot be differentiated solely on the basis of morphological characters. Therefore, species complexes represent a major problem in malaria vector contr...

Thermohaline gradients and frontal regimes in the northwestern Tropical Atlantic

Abstract. At the edge of the Amazon River plume, stirring by the North Brazil Current (NBC) and its eddies creates sharp surface thermohaline gradients on scales of O(1–100) km. This study provides a comprehensive picture of these gradients and fronts associated with the region's...

Genetic distance and pollinator sharing shape divergence in floral volatiles in closely related dioecious Ficus species

Abstract Premise Floral scent is central to host recognition in the fig–fig wasp mutualism, yet how scent divergence relates to pollinator sharing among closely related dioecious Ficus species remains unclear. Methods We analyzed volatile organic compounds (VOCs) from four pairs...

Termites play a crucial role in forming major tropical soils: insights from a deep Ferralsol

Abstract Soil bioturbation is increasingly recognized as a key driver of pedogenesis in tropical ecosystems, influencing above- and below-ground biodiversity, nutrient cycling, and aggregate stability across different spatial and temporal scales. This ecological process may play...

Planktonic foraminifera iodine ∕ calcium ratio: is it a proxy for dissolved oxygen in the ocean?

Abstract. Direct observations indicate a declining trend in ocean oxygen concentrations, which is not quantitatively captured by models. The complexity of oxygenation variability, linked to both physical and biochemical parameters, must be investigated across different modern cli...
