Evaluation of Different Types of Aerosols From Wildfires in South America Using Ground‐Based Observations, Reanalysis and CMIP6 Models

International Journal of Climatology, Volume 45, Issue 16, 30 December 2025.
We evaluate MERRA‐2 and CAMS reanalysis products against AERONET observations and compare them with CMIP6 models. CAMS shows better performance in capturing fire‐derived aerosols (BC AOD and OC AOD), with peak values during the dry season (August–October). Both reanalyses capture spatiotemporal AOD variability, although systematic overestimation occurs

Species Limits and Hybridization in Andean Leaf‐Eared Mice (Phyllotis)

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Diversification of Phyllotis coincided with mid‐ to late‐Pleistocene climate change. Species delimitation revealed cryptic diversity within several nominal forms. Genomic analyses revealed evidence for introgressive hybridization. ABSTRACT Leaf‐eared mice (genus Phyllotis) are among the most widespread and abundant small mammals in the Andean Altiplano,

Biochar‐Amended Soils: A Water‐Saving Strategy for Quinoa Cultivation in the Andes

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 1, March 2025.
ABSTRACT Introduction Previous studies showed that biochar amended soils significantly enhanced the growth and yield of quinoa under water limitations. So it becomes an emerging agronomic strategy to consider for sustainable quinoa production. Biochar can specifically be considered for the area particularly receiving low annual rainfall and more ...

Characterization of virus species associated with sweet potato virus disease in Costa Rica and riboprobe development for its rapid detection

Plant Pathology, Volume 74, Issue 2, Page 413-421, February 2025.
Sweet potato feathery mottle virus and sweet potato chlorotic stunt virus have high prevalence in Costa Rica. Riboprobes are a cost‐effective alternative to RT‐PCR for virus detection in large‐scale screenings. Abstract Sweet potato (Ipomoea batatas) is a crucial crop for food security and economic stability in many regions, including Costa Rica.
