Unearthing Mesozoic beetles through micro‐computed tomography: A new family of Archostemata and the first representatives of Ommatidae and †Notocupes from the Crato Formation

open access: yesSystematic Entomology, Volume 51, Issue 3, July‐September 2026.
First formally described Archostemata beetles from the Lower Cretaceous Crato Formation are reported, representing the earliest records of the suborder from western Gondwana. Micro‐computed tomography enabled three‐dimensional reconstruction of partially exposed fossils, revealing previously hidden dorsal and ventral morphological characters relevant ...

Ophiolitic Remnants from the Upper and Intermediate Structural Unit of the Attic-Cycladic Crystalline Belt (Aegean, Greece): Fingerprinting Geochemical Affinities of Magmatic Precursors

open access: yesGeosciences, 2017
The ophiolitic rocks of the Attic-Cycladic crystalline belt are considered of key importance for understanding the Mesozoic tectonic evolution of the Aegean region. Unresolved questions concern their tectono-stratigraphic relationships across the region.

Update of the risk assessment on emerging and novel brominated flame retardants in food

open access: yesEFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The European Commission asked EFSA to update its 2012 risk assessment on Emerging and Novel brominated flame retardants (BFRs) in food. Since the previous Opinion, further information was collected for a total of 27 BFRs. The CONTAM Panel concluded that TDBPP, DBPNG and TBNPA are considered genotoxic and carcinogenic.

Late Palaeozoic-early Mesozoic fore-arc basin Sedimentary rocks at the Pacific margin in Western Antarctica

open access: yes, 1981
We infer that the Trinity Peninsula Group of the Antarctic Peninsula was deposited in a fore-arc basin(s) of composite type located between the Gondwanian arc massif (consisting of plutonic and older gneissose basement rocks) and a subduction complex ...

Methods to estimate marine functional connectivity: A primer

open access: yesEcological Applications, Volume 36, Issue 4, June 2026.
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

On the origin of the North Pacific arcs [PDF]

open access: yes, 2004
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

Individual specialization and temporal changes in Antarctic fur seal trophic ecology from a multi‐tracer approach

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Substantial individual variation in diet and foraging strategies can exist within populations. These differences can enhance individual foraging efficiency, reduce intraspecific competition, and provide fitness advantages that increase the resilience of a population.

Relationship between Tmax and Vitrinite Reflectance in the fore-arc basins of South-West of Ecuador

open access: yes, 2020
La cuantificación de Ro y Tmax son dos técnicas independientes utilizadas para caracterizar la madurez termal de las rocas. Más aún, varios estudios han demostrado que existe una relación lineal-directa entre estos dos parámetros. Para el caso de las cuencas del Sur-Oeste de Ecuador, se ha establecido una ecuación [Ro = 0.0228*Tmax – 9.21] basada en ...

When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey
