Biotic Assembly of the Species of Triatomini (Hemiptera: Reduviidae: Triatominae) in the Mexican and South American Transition Zones

Journal of Biogeography, Volume 52, Issue 10, October 2025.
ABSTRACT Aim To infer the biogeographic history of the Triatomini by evaluating how their species became part of the biogeographic transition zones of the New World. This group of blood‐feeding insects includes key vectors of Chagas disease. Understanding their dispersal and diversification over geological time may help elucidate the temporal dynamics ...

Análisis estructural del Anticlinal de Zipaquirá (Cordillera Oriental, Colombia)

, 2016
Se llevó a cabo un análisis estructural a partir de una revisión cartográfica, datos cinemáticos, datos de fracturas y secciones transversales a lo largo del Anticlinal de Zipaquirá (AZ) que permitieran plantear la evolución cinemática del pliegue. El AZ es una estructura que presenta curvatura en su eje axial y tiene un rumbo general en dirección N30E.

A Review of the Status of Sharks, Rays and Chimaeras of Panama to Guide Research and Conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT Chondrichthyan fishes (sharks, rays and chimaeras) are a group of high conservation concern globally. Species are impacted by varying threats, although fishing pressure is the primary stressor causing population declines. Panama comprises both Pacific and Caribbean coastlines with a diversity of estuarine and marine habitats supporting small ...

Mapping Peatland Distribution and Quantifying Peatland Below‐Ground Carbon Stocks in Colombia's Eastern Lowlands

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 4, April 2025.
Abstract The extent and distribution of tropical peatlands, and their importance as a vulnerable carbon (C) store, remain poorly quantified. Although large peatland complexes in Peru, the Congo basin, and Southeast Asia have been mapped in detail, information on many other tropical areas is uncertain.

Rock Glacier Kinematics in the Valles Calchaquíes Region, Northwestern Argentina, From Multi‐Temporal Aerial and Satellite Imagery (1968–2023)

Permafrost and Periglacial Processes, Volume 36, Issue 1, Page 123-136, January/March 2025.
ABSTRACT In semiarid mountain ranges, rock glaciers constitute an important part of the periglacial environment. However, quantitative data on the state of rock glacier activity remain scarce. Here, we derive kinematic information on rock glaciers located in the Valles Calchaquíes region (24–25° S) in Argentina from optical feature tracking in ...

Uncovering the Potential of Carbon Stocks and Nutrients in Livestock Systems in Zamora Chinchipe

Applied and Environmental Soil Science, Volume 2025, Issue 1, 2025.
Zamora Chinchipe’s soil supports the biodiversity of its forests, but small farmers also use it for agricultural activities. Unsustainable management of these areas contributes to expanding the agricultural frontier, which generates pressure on ecosystems.
