Características morfológicas de las cianobacterias y fitoplancton dominante en tres embalses de Antioquia: un enfoque basado en la forma y el biovolumen

open access: yesRevista U.D.C.A Actualidad & Divulgación Científica, 2019
El desarrollo masivo de cianobacterias y la contaminación por cianotoxinas constituyen una problemática ambiental de especial interés en los sistemas acuáticos, debido a los diversos impactos negativos que los florecimientos (blooms) de cianobacterias ...

Genomic Connectivity and Adaptation Signals of the Freshwater Sponge Ephydatia muelleri Across Its Distribution

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Genetic connectivity and local adaptation were examined across the distribution of the freshwater sponge Ephydatia muelleri. Because it occupies an exceptional breadth of freshwater environments across a broad geographic range, this species offers key insights into biogeographic processes shaping genetic structure and adaptation in inland ...

A New Fuel Design for Two Different HW Type Reactors

open access: yesScience and Technology of Nuclear Installations, Volume 2011, Issue 1, 2011., 2011
A new fuel element (called CARA) designed for two different heavy water reactors (HWRs) is presented. CARA could match fuel requirements of both (one CANDU and one unique Siemens′s design) Argentine HW reactors. It keeps the heavier fuel mass density and hydraulic flow restriction in both reactors together with improving both thermomechanic and ...

Modeling nature‐based restoration potential across aquatic–terrestrial boundaries

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Today, few watersheds remain untouched by global change processes arising from climate warming, impoundments, channelization, water extraction, pollution, and urbanization. The need for restoration has resulted in a myriad of interventions, generally performed at small scales, which have limited measurable impact in restoring biodiversity and

Systematic and taxonomic revision of the genus Austrocactus (Cactaceae) based on morphology and genome wide SNP‐data

open access: yesTAXON, Volume 74, Issue 2, Page 386-416, April 2025.
Abstract The post‐Miocene climatic history of arid environments in South America has been identified as a key driver of dispersal and diversification, particularly among plant groups such as Cactaceae. Despite their iconic status, many cactus genera remain poorly understood, and comprehensive taxonomic and systematic revisions using morphological and ...

Genome‐resolved metagenomics reveals the effect of nutrient availability on bacterial genomic properties across 44 European freshwater lakes

open access: yesEnvironmental Microbiology, Volume 26, Issue 6, June 2024.
We sequenced water samples from 44 lakes by shotgun sequencing, followed by binning them into metagenome‐assembled genomes. The genomic information from these genomes along with nutrient measurements was used for phylogenetic and ecological analysis. Abstract Understanding intricate microbial interactions in the environment is crucial.

Wild relatives of potato (Solanum L. sec. Petota) poorly sampled and unprotected in Colombia

open access: yesCrop Science, Volume 64, Issue 1, Page 225-243, January/February 2024.
Abstract Wild potato relatives (Solanum L. sec. Petota) play a vital role in crop improvement, understanding crop evolution, and conserving potato diversity. However, these invaluable resources are often neglected and underutilized and are susceptible to threats such as climate change, urbanization, and agricultural expansion. Little is known about the
