Climate and hybridization shape stomatal trait evolution in Populus

New Phytologist, Volume 249, Issue 2, Page 792-809, January 2026.
Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

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 ...

Sexagesimal scale for mapping human genome Escala sexagesimal para mapear el genoma humano

Revista Chilena de Historia Natural, 2001
In a previous work I designed a diagram of the human genome based on a circular ideogram of the haploid set of chromosomes, using a low resolution scale of Megabase units.

Modulation of the Proteostasis Machinery to  Overcome Stress Caused by Diminished Levels of  t6A‐Modified tRNAs in Drosophila

Biomolecules, 2017
Transfer RNAs (tRNAs) harbor a subset of post‐transcriptional modifications required for structural stability or decoding function. N6‐threonylcarbamoyladenosine (t6A) is a universally conserved modification found at position 37 in tRNA that pair A ...

Gut Microbiota Diversity and Function in Adults With Type 2 Diabetes, Alzheimer’s Disease, and Both Conditions

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Introduction Type 2 diabetes mellitus (T2DM) is known to increase the risk of Alzheimer’s disease (AD), but the role of the gut microbiota in this relationship is not fully understood. This study investigated the gut microbiota profiles of adults with T2DM, adults with AD, both conditions (AD–T2DM), and healthy controls to identify patterns associated ...

Genetic modulators of metabolic dysfunction-associated steatotic liver disease (MASLD) and their epistatic interactions: from in vitro and animal models to clinical outcomes

BMC Medical Genomics
Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as NAFLD (non-alcoholic fatty liver disease), is a growing global concern, affecting nearly a third of the world’s population.

Exonic Variation and Its Clinical Impact in 7221 Old Order Amish

American Journal of Medical Genetics Part A, Volume 197, Issue 12, December 2025.
ABSTRACT The Amish of Lancaster County, PA has been the focus of genetic studies for many years due to its demographic history and unique genetic makeup that includes a historical bottleneck event and subsequent genetic drift, resulting in a marked decrease in genetic diversity and increased frequency of some variants that have substantially shaped the

Genome dynamics, genetic complexity and macroevolution Dinámica del genoma, complejidad genética y macroevolución

Revista Chilena de Historia Natural, 2003
Genome data analysis indicates that the major evolutionary transitions have been driven by substantial increases in genomic complexity. These increases, accounting for novelty in evolution, have proceeded mainly by gene duplication.

La genètica de les migracions humanes: Seguint el rastre de les migracions a través del nostre genoma

Mètode Science Studies Journal: Annual Review, 2015
La reconstrucció de les migracions humanes és possible gràcies a la informació aportada per diverses disciplines. L’estudi de la diversitat genètica de les poblacions humanes actuals ens revela quins han estat els esdeveniments demogràfics i moviments ...
