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...

Enabling climate action: A nexus approach for delivering co-benefits across biodiversity, water, food, and health

Climate response options rarely affect biodiversity, water, food, and health in uniform ways. This comparative analysis examines why technically viable response options generate uneven cross-nexus outcomes, and how governance and justice conditions shape whether these outcomes be...

Lithochloron , a new genus of green algae residing in coral skeleton (Cladophorales, Chlorophyta)

Abstract Coral skeletons host diverse microbial communities, including endolithic green algae that contribute to holobiont functioning. The siphonous green alga Ostreobium (Bryopsidales) is arguably the best‐known coral endolith, but recent environmental sequencing has indicated...

Ebola-virus outbreaks are teleconnected with macroclimatic oscillations

Ebola viruses’ ecology is known to be affected by climate, which is globally monitored using macroclimatic oscillation indices. We tested whether any of 26 macroclimatic oscillation indices were teleconnected with Ebola virus disease (EBOD) outbreaks. We compiled an updated datab...

Unravelling the magma source and plumbing systems beneath the submarine volcanoes of Bransfield Strait (Antarctica) with stable and noble gas isotopes

Abstract Oxygen and hydrogen isotope geochemistry, together with helium, neon and argon isotope systematics, are powerful tools for tracing magma sources and magma plumbing system processes beneath volcanic systems. Characterising them is crucial for understanding volcanic system...

Microplastics in porifera: a systematic review

Marine sponges (Phylum Porifera) are ecologically key filter feeders playing central roles in water purification and habitat structuring across all latitudes. Their filter-feeding behaviour and established use as bioindicators of chemical pollution make them strong candidates for...

Mulch Films: Degradation Analysis and Ecotoxicological Assessment in Marine and Terrestrial Environments

Agricultural soils have been identified as significant sinks for plastic waste from mulch films, which in turn can reach aquatic ecosystems. As an alternative to conventional materials, there has been growing interest in biodegradable mulch films, but their environmental behavior...

Unravelling the trophic ecology of the ocean sunfish Mola mola in the western Mediterranean Sea through integrated approaches

Abstract Understanding the trophic ecology of marine megafauna is essential for elucidating their ecological roles and supporting effective conservation strategies. The ocean sunfish ( Mola mola ) is the second-largest bony fish worldwide and has a broad distribution, including t...

High-Resolution Mapping of Forest Vegetation Types Using Multiplatform Imagery and Advanced Classification Techniques

Accurate and up-to-date information is essential for environmental monitoring, particularly in regions characterized by complex topography and heterogeneous landscapes. This study presents a multisource remote sensing–based approach for forest vegetation classification on La Palm...

A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...
