A Multi‐Tissue Transcriptomic Resource for the Brahminy Blindsnake Indotyphlops braminus (Squamata: Typhlopidae)

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
We analyzed multi‐tissue expression patterns in the all‐female, parthenogenetic, and triploid Brahminy blindsnake (Indotyphlops braminus) using PacBio and Illumina RNA‐seq to better understand polyploidy and asexual reproduction in vertebrates. By characterizing differential expression and co‐expression networks across the ovary, heart, liver, skin ...

Ground-Water/Surface-Water Interactions in a Karst Aquifer

open access: yesIntegrated Surface and Ground Water Management, 2001
Ground-water/surface-water interactions in of the largest aquifer systems in the United States were analyzed in this article. The Edwards karst aquifer of Texas exhibits unique ground-water recharge processes. It is also located in a region of pronounced precipitation variability, the dominant controlling factor of ground-water recharge.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

open access: yesJournal of Quaternary Science, Volume 41, Issue 8, Page 1263-1281, November 2026.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.
