Mitogenomic Insights Into the Ancient Split and Cryptic Diversity of the Poecilochirus carabi Complex (Acari: Mesostigmata)

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
Mitochondrial genomes of Poecilochirus mites reveal a paraphyletic genus and uncover deep cryptic speciation within the P. carabi complex. Two divergent lineages (BJ1 and BJ2) show a cox1 genetic distance of 0.409 and an Eocene divergence time of ~52.4 million years ago, predating the split between two morphologically recognized species.

Phylogenetic structure of conifers in regional floras in relation to climate and environmental heterogeneity worldwide

open access: yesEcography, Volume 2026, Issue 10, October 2026.
Despite having only about 670 species worldwide, conifers are one of the ecologically and economically most important plant groups. They have a rich fossil record and previous studies have shown that their current diversity is the result of past radiations, extinction, and dispersal events, restricting many genera to either the Northern or Southern ...

Stable but Transient—Episodic Sensitivity in a Buffered German Karst Headwater Stream

open access: yesHydrological Processes, Volume 40, Issue 10, October 2026.
Baseline carbonate chemistry revealed coherent, degassing‐controlled patterns across the stream. Although warm low‐flow and rewetting periods temporarily increased system variability, carbonate buffering persisted (I). In addition, gas transfer and local hydromorphology decoupled CO2 evasion from pCO2 in a spring‐fed karst headwater stream (II ...

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

open access: yesJournal of Quaternary Science, Volume 41, Issue 7, Page 1060-1077, October 2026.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Ostracod faunal and geochemical evidence for the impact of Hoxnian (MIS 11c) sea levels in eastern England

open access: yesJournal of Quaternary Science, Volume 41, Issue 7, Page 1078-1088, October 2026.
ABSTRACT Marine isotope substage 11c (~426–366 ka) is widely regarded as the most recent Pleistocene interglacial that is broadly analogous to the Holocene. The timing and magnitude of sea‐level changes during MIS 11 have been much debated, particularly concerning whether sea levels were significantly higher than during the Holocene. Empirical evidence
