Biogeographical Regionalisation of Southern Africa Using Tenebrionid Beetles: A Multi‐Scale Analysis of Diversity and Environmental Drivers

open access: yesJournal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim Southern Africa's remarkable environmental heterogeneity drives high biodiversity and endemism, yet biogeographical regionalisations often overlook invertebrates despite their ecological significance. This study presents a comprehensive regionalisation of southern Africa using tenebrionid beetles (Coleoptera: Tenebrionidae), a diverse and ...

Planktic foraminiferal evidence for variation in the strength of the Agulhas Current during the Pliocene (4.6-2.6 Ma)

open access: yesJournal of the Palaeontological Society of India
The Pliocene, although predominantly warm, experienced four major glacial events at 4.8, 4.0, 3.3, and 2.7 million years ago (Ma), altering ice sheet dynamics and ocean circulation.

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 5, Page 1399-1420, May 2026.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Inferring Time‐to‐Speciation From Hybrid Zone Analysis Informs Assessments of Taxonomic Inflation

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Measuring gene flow across hybrid zones can provide a direct evaluation of reproductive isolation (RI) between evolutionary divergent lineages. Geographic‐explicit modelling of gene flow across hybrid zones, known as cline analysis, thus offers a gold standard for species delimitation under the biological species criterion.

Rapid Land Surface Uplift and Groundwater Recovery Observed During the Syrian War

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Recent geopolitical upheaval in Syria is driving regional growth by returning populations, which increases demands on water resources. In northwest Syria, widespread cropland abandonment during the Syrian War starting in 2011 drastically changed the hydrological regime of the region.
