Filogenia del reino Chromista

Revista Sextante, 2019
La clasificación de los organismos vivos ha sido modificada numerosas veces, debido a que algunos grupos han sido difíciles de catalogar. Actualmente se reconocen siete reinos: Animalia, Plantea, Protozoa, Fungí, Archaea, Bacteria y Chromista.

From colorectal cancer pattern to the characterization of individuals at risk: Picture for genetic research in Latin America

International Journal of Cancer, Volume 145, Issue 2, Page 318-326, 15 July 2019., 2019
Colorectal cancer (CRC) is one of the most common cancers in Latin America and the Caribbean, with the highest rates reported for Uruguay, Brazil and Argentina. We provide a global snapshot of the CRC patterns, how screening is performed, and compared/contrasted to the genetic profile of Lynch syndrome (LS) in the region.

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

TAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Phylogenomics and biogeography of the cleptoparasitic bee genus Triepeolus Robertson (Hymenoptera: Apidae), with a revised subgeneric classification of Triepeolus and its sister genus, Epeolus Latreille Filogenómica y biogeografía del género de abejas cleptoparásitas Triepeolus Robertson (Hymenoptera: Apidae), con una clasificación subgenérica revisada para Triepeolus y su género hermano, Epeolus Latreille

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...

Probabilistic modelling improves relative dating from gene phylogenies

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2461-2471, October 2025.
Abstract Establishing the timing of past evolutionary events is a fundamental task in the reconstruction of the history of life. State‐of‐the‐art molecular dating methods generally involve the reconstruction of a species tree from conserved, vertically evolving genes and the assumption of a molecular clock calibrated with the fossil record.
