Contribution to a reference library of DNA barcodes of Colombian freshwater fishes [PDF]
Biodiversity Data Journal, 2022 The Barcode of Life initiative was originally motivated by the large number of species, taxonomic difficulties and the limited number of expert taxonomists.

Dataset of concentrations of mercury and methylmercury in fish from a tropical river impacted by gold mining in the Colombian Pacific [PDF]
Data in Brief, 2020 This data article includes information on the impact of gold mining along five zones of a tropical river in the Pacific region of Colombia. The concentrations of total mercury (THg), total length, mertimercury (MeHg) were determined in 16 species of fish.

Method for estimating discharge, hydraulic depth, and mean velocity in rivers through spatial interpolation of at-a-station hydraulic geometry in data- scarce regions [PDF]
MethodsXReliable discharge estimation is essential for water resource management, yet many regions lack sufficient hydrological stations. To address this limitation, we propose the Spatial Hydraulic Geometry Interpolation (SHGI) method, which estimates discharge

The Quantified Galloway Ternary Diagram of Delta Morphology. [PDF]
J Geophys Res Earth SurfAbstract Waves, rivers, and tides shape delta morphology. Recent studies have enabled predictions of their relative influence on deltas globally, but methods and associated uncertainties remain poorly known. Here, we address that gap and show how to quantify delta morphology within the Galloway ternary diagram of river, wave, and tidal sediment fluxes.

Ecoregional and altitudinal distribution of the principal malaria vectors in Colombia [PDF]
Malaria JournalBackground In Colombia, with over 100,000 cases reported in 2023, malaria is a significant vector-borne disease. The wide range of climates and highly variable topography and land cover of the country support a high species richness, favouring different ...

Estimating taxonomic and functional structure along a tropical estuary: linking metabolic traits and aspects of ecosystem functioning [PDF]
Microbiology SpectrumMicrobial life forms are among the most ubiquitous on Earth, yet many remain understudied in Caribbean estuaries. We report on the prokaryote community composition of the Urabá Estuary in the Colombian Caribbean using 16S rRNA gene-transcript sequencing.
