Fish diversity of Colombian Andes-Amazon streams at the end of conflict is a reference for conservation before increased land use. [PDF]
Ecol EvolAquatic ecosystems in the Andes‐Amazon transition zone of Colombia are now at high risk due to expanded human activities after peace agreements in 2016 ended armed conflict. Fish communities exhibit altitudinal biodiversity gradients that are consistent in space and time, and that need to be accounted for conservation and management considerations. Our

Wild or Introduced? Investigating the Genetic Landscape of Cacao Populations in South America. [PDF]
Ecol EvolCacao populations span a continuum from wild to domesticated forms, shaped by complex patterns of human influence and selection. Using RAD‐sequencing, we show that native Upper Amazonian populations harbor the highest genetic diversity, while the Guiana group likely represents an isolated wild lineage and Amelonado shows clear signals of artificial ...
