Frozen and Scorched: Genomic Signatures of Adaptive Divergence and Hibernation in the Living Fossil Dromiciops

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We evaluated adaptation to torpor and hibernation in the genus Dromiciops by comparing it with both torpid and non‐torpid marsupials, and investigated divergent selection signals between its two species. For the ancestral node, we identified positive selection in the genes PFKFB2, LAMP3, OTX1, and RAPSN, alongside an enrichment of pathways potentially ...

Language ecologies and dynamics in the ancient Central Andes

open access: yes
Abstract This chapter sketches ways of comprehending Andean patterns of language use in the context its social and cultural meaning . . ., with particular reference to the early historical situation that might contain elements for models that can be applied to (late) prehistory.

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

Temperature fluctuations controlled episodic rockfall activity in the Rwenzori Mountains (Uganda) during the Holocene

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The alignment between rockfall deposit surface exposure 10Be ages and Holocene temperature records suggests that major rockfall events occurred episodically in response to climatic fluctuations. We conclude that temperature and its evolution enabled mechanical, chemical or bio‐chemical enhancement of fracture progression.

Seismic Fragility and Vulnerability of Partially Grouted Flexural‐Controlled Reinforced Masonry Buildings in Colombia

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
This paper presents the development of analytical fragility and vulnerability functions for flexure‐controlled partially grouted reinforced masonry (RM) buildings that are representative of Colombian urban areas, with the goal of enhancing national seismic risk assessments.
