From Compression to Extension in the Eastern Pyrenees: New Insights From Low‐Temperature Thermochronology

open access: yesTectonics, Volume 45, Issue 1, January 2026.
Abstract The tectonic evolution of the Eastern Pyrenees from the orogenic mountain building to the post‐orogenic dismantling is still debated. Since the Oligocene, the Gulf of Lion rifting in the Western Mediterranean superimposed crustal extension in this eastern part of the Pyrenean belt, while compressional tectonics persisted in the Central ...

Evaluating permeability and groutability of Souk Tleta dam site based on Lugeon tests, RQD, SPI and trial grouting

open access: yesJournal of Materials and Engineering Structures, 2020
This study is conducted mainly to evaluate the permeability and the groutability at Souk Tleta dam site.  It is an embankment dam with a height of 95 m and a crest length of 200m located in the Tizi-Ouzou province in Northern Algeria.

Diversification and evolution of Hawaiian Megalagrion damselflies (Pinapinao, Odonata: Coenagrionidae) Ka Ho‘omāhuahua a me ke Kumu Ho‘omohala o nā Pinapinao Megalagrion o Hawai‘i (Odonata: Coenagrionidae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The ancestor of today's pinapinao, Hawaiian Megalagrion damselflies, diverged from Ischnurinae around 51 MA and likely evolved for over 20 MA before colonizing the Northwestern Hawaiian Islands. An ancestor of Megalagrion colonized the Northwestern Hawaiian Islands and diversified into ecological niches with four new breeding habitats and two new gill ...

A new termite bug in Miocene amber from the Dominican Republic (Hemiptera, Termitaphididae)

open access: yesZooKeys, 2009
A new species of the termite bug genus Termitaradus Myers (Aradoidea: Termitaphididae) is described and figured based on a single female preserved in Early Miocene (Burdigalian) amber from the Dominican Republic. Termitaradus mitnicki sp. n. differs from

The Upper Burdigalian scleractinian corals from Bonifacio (South Corsica).

open access: yes, 2015
Au Burdigalien supérieur, des récifs coralliens se sont développés dans la Formation de Cala di Labra, aux alentours de Bonifacio (Corse-du-Sud, France). Ils sont organisés en trois épisodes successifs R1, R2 et R3. La faune corallienne comprenant 16 espèces récifales, est décrite pour la première fois.

Out‐of‐Africa: Origin of the Disjunct Distribution of Paleotropical Eneopterinae Crickets (Gryllidae, Xenogryllini)

open access: yesZoologica Scripta, Volume 55, Issue 1, Page 116-130, January 2026.
ABSTRACT Many groups of terrestrial plants and animals display a disjunct distribution pattern in the Paleotropics, being found almost exclusively in tropical Africa and Asia. The origin of such a pattern may be manifold, particularly for older lineages where plate tectonics potentially played an important role.

Phylogeny and Evolution of the Genus Abax: A Genetic and Biosystematic Approach (Carabidae, Pterostichini)

open access: yesJournal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
In this article, we carry out a study of the genus Abax (Carabidae, Pterostichini) based on mitochondrial and nuclear markers to test hypotheses about its evolutionary history in an integrative taxonomical framework. The subgenera Pterostichoabax (four species) and Abacopercus (monotypic) are likely natural taxa supported by all data.
