Paleogene Glyptodontidae Propalaehoplophorinae (Mammalia, Xenarthra) in extra-Patagonian areas

, 2015
Paleogene records of Cingulata Glyptodontidae are scarce. The only well described comes from the Paleogene of Argentine Patagonia. Two subfamilies have been reported for that period: Glyptatelinae and Propalaehoplophorinae.

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, Volume 101, Issue 3, Page 1568-1581, June 2026.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Quantification of the Eocene–Oligocene transition in the Zagros Foreland Basin: Palaeogeographic control on sequence architecture and tectonic signal preservation

The Depositional Record, Volume 12, Issue 3, June 2026.
New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact

How Does the Phasianidae Maintain Its Diversity in Central China?

Ecology and Evolution, Volume 16, Issue 6, June 2026.
ABSTRACT The hypothesis of allopatric speciation suggests that spatial separation is the major driver to speciation. The ecological niche theory suggests that differentiations in niche dimensions allow more species to co‐exist in ecological communities.
