In Search of Congenital Chagas Disease in the Sierra Nevada de Santa Marta, Colombia [PDF]
The American Journal of Tropical Medicine and Hygiene, 2019 Chagas disease remains a major impediment to sustainable socioeconomic development in Latin America. Transplacental transmission explains the persistence of transmission in urban areas, in non-endemic regions, and in areas with an established interrupted vectorial transmission. One of every five cases of congenital Chagas disease in the world occurs in

A Field-Deployable eDNA Metabarcoding Workflow Including De Novo Reference Assembly for Characterising Understudied Biodiversity Hotspots. [PDF]
Mol Ecol ResourABSTRACT Field‐deployable DNA metabarcoding offers a transformative approach to biodiversity research and monitoring, yet its application remains limited due to technical constraints and a lack of reference data in poorly studied ecosystems. Combining isothermal Recombinase Polymerase Amplification (RPA) and Oxford Nanopore sequencing, we introduce a ...

The Leading Edge Matters Too: Fitness and the Expression of Adaptive Differentiation Are Greatest at the High-Elevation Edge of a Species' Range. [PDF]
Ecol LettWe tested hypotheses about adaptation across elevational range limits in Erythranthe laciniata, a montane plant endemic to the Sierra Nevada. Using common garden experiments, we found highest fitness and strongest climate adaptation at high elevations, suggesting potential for range expansion and challenging assumptions of limited adaptive potential at

Genome assembly of the endangered Santa Marta Harlequin Toad, Atelopus laetissimus , endemic to the Sierra Nevada de Santa Marta of Colombia [PDF]
Journal of HeredityAbstract Despite the critical conservation status of many harlequin toads (Anura: Bufonidae: Atelopus) and their significance in elucidating the impacts of emerging diseases on amphibians, genomic data for this genus are scarce. Here, we present a de novo genome assembly of the Santa Marta Harlequin Toad, Atelopus laetissimus, using ...
