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

Ecology 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.

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

Journal of Applied Toxicology, Volume 46, Issue 8, Page 2599-2622, August 2026.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

DNA barcoding for identification of species involved in wildlife strikes at Brazilian airports

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
A collaborative network of 42 Brazilian airports applied DNA barcoding to identify 80 species involved in wildlife strikes. Among them, 32 species (17 birds and 15 bats) were not currently available in Brazil's wildlife strike reporting database, underscoring the value of molecular tools for strengthening wildlife strike monitoring.
