Laboratorio de Sistemática, Genética y Evolución

El LabSGE se encuentra adscrito a la Escuela de Ciencias Biológicas, en la Universidad Nacional de Costa Rica (UNA)

El LabSGE tiene como objetivos:
Estudiar el proceso adaptativo en los elementos de la biodiversidad. Estudiar los mecanismos de cambio evolutivo en los elementos de la biodiversidad. Identificar los factores evolutivos e históricos responsables de proceso de especiación. Estudiar la historia evolutiva de los diferentes elementos de la biodiversidad.

An international team of scientists has built the largest and most detailed bird family tree to date—an intricate chart delineating 93 million years of evolutionary relationships between 363 bird species, representing 92% of all bird families.

Tetraopes longhorn beetles are known for their resistance to milkweed plant toxins and their coevolutionary dynamics with milkweed plants (Asclepias). This association is considered a textbook example of coevolution, in which each species of Tetraopes i...

🚨NEW PAPER📖
Lars Dietz and co-authors demonstrate with empirical genomic data (universal single-copy orthologs; USCOs) the viability of a concept for a unified and thus more sustainable framework for species inference suitable for all Metazoa, as a standardized extension of classical single-marker DNA Barcoding.

Simulating data helps a researcher gain a deeper understanding of the models and their assumptions and establish the reliability of their estimation approaches. Wider adoption of data simulations by biologists can improve statistical inference, reliability and open science practices.

Mitochondrial DNA (mtDNA) sequences are often found as byproducts in next-generation sequencing (NGS) datasets that were originally created to capture genomic or transcriptomic information of an o...

The authors incorporate mechanistic information about lizard physiological responses to heat into predictions of trait variation across time and space, finding that the range of functional traits is more constrained in locations where the local climate strongly selects for thermal performance.

Trace element ratios (strontium/calcium) in teeth of Pleistocene Homo erectus and fossil orangutans (Pongo sp.) reveal different dietary strategies and contrasting adaptations to seasonal food resources. H. erectus but not Pongo sp. was able to buffer against seasonal food oscillations by exploiting...

Adaptation to new environments often involves changes in gene expression. This study shows a role of ancestral gene expression plasticity in heavy metal adaptation of two independent lineages of Silene uniflora.
