Environmental DNA, Volume 8, Issue 3, May–June 2026.This review reveals major genetic data gaps for Philippine mangrove fauna, especially invertebrates, limiting species‐level eDNA detection. By compiling 48 years of biodiversity records and assessing reference library coverage, it highlights the need for targeted sequencing and shows how integrating eDNA with conventional surveys strengthens monitoring

Boletín de Geología, 2023 Several Cretaceous amber-bearing localities were recently discovered, including the Oriente Basin of Ecuador (Hollín Formation), and the Eastern Cordillera of Colombia (Une Formation at La Popa mine). A palynological study of 48 samples was carried out to date them and assess their broad floristic content.

American Ethnologist, Volume 53, Issue 2, Page 171-182, May 2026.Abstract In Colombia's northeastern borderlands, agrarian economies shape how disease risk and stigma are understood and managed. As shown in ethnographic fieldwork in and around the Catatumbo region, cutaneous leishmaniasis—a sandfly‐transmitted disease that produces chronic skin lesions—appears in two radically different guises across adjacent ...

A taxonomic update of the genus Clavija (Theophrastaceae) in Colombia and Ecuador
Nordic Journal of Botany, Volume 2026, Issue 3, March 2026.Two species of Clavija are described as new to science: C. neivea (Department Huila Colombia), which is similar to C. pungens (Willd. ex Roem. & Schult.) Decne. of coastal Ecuador, but distinguished by its chiefly elliptic leaf blades with less serrate margins and 4‐merous flowers; C. zamorae (Prov.

Conodonts from the Cambrian-Ordovician Boundary in the Cordillera Oriental, NW Argentina
Stratigraphy, 2016 The Cambrian-Ordovician boundary in NW Argentinawas originally proposed for the lower upper section of the Cardonal Formation in the Amarilla Creek, Cajas Range, Cordillera Oriental of Jujuy, based on the first appearance of the conodont Cordylodus lindstromi.

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

RIVER DYNAMICS IN THE CORDILLERA ORIENTAL OF THE ANDES (NORTHWESTERN ARGENTINA)
Italian Journal of Engineering Geology and Environment, 2008 The paper describes the river dynamics and slope dynamics processes taking place in the section of the Andes in northwestern Argentina (Cordillera Oriental Unit), analyzing the causes in terms of agents, factors and conditions. The rising of this area of the chain is at the basis of the erosion and debris flow phenomena found there, which are favored ...
