Evolutionary signatures of the erosion of sexual reproduction genes in domesticated cassava (Manihot esculenta) Abstract. Centuries of clonal propagation in cassava (Manihot esculenta) have reduced sexual recombination, leading to the accumulation of deleterious muta

Coffee agrosystems with cover trees, a common practice in Veracruz, Mexico. Shows better soil parameters and plants health leading to sustainable management.
This project was a little step to recognize this traditional practices as an important ecological contribución.

Last year I moved to metagenomics and field work, today as a result i'm excited to share this preprint in which we highligth the traditional coffee agrosystems effects on soil health and bacterial diversity.

A radical evolutionary makeover gave echinoderms their unusual body plan Gene-expression maps show how starfish evolved their five-fold symmetry.

Echinoderms already undergo large-scale metamorphosis during larval development, so there are lots of gene 'switches' that produce different patterning.

The loss of a few of these (say, for "trunk") creates an animal that is a sort of "Oops, All-Arms!" body plan.

Hawaiian bobtail squid maintain distinct microbiota in different organs, including bioluminescent bacteria in their light organs, by deploying immune factors with tailored expressions in each niche. In PNAS: https://ow.ly/QxLo50XPnyS

maybe a good reason to keep going this year

I hope this year will come with new colaborations and the first publication from my current postdoc work... And I hope all my friends have so much success

GBE | To Migrate or not to Migrate? Exploring the Genomic Basis of Partial Migratory Behavior in Bats Group of migratory Leptonycteris yerbabuenae females, or lesser long-nosed bat, entering the large maternity cave located in the El Pinacate y Gran Desierto de Altar Biosphere Reserve, Sonora, Mexico.

Migration is widespread in animals, but little is known about its genetic regulation. Peralta et al. compared genomes of lesser long-nosed bats, identifying 10 genomic regions with signatures of selection linked to migration.

I noticed the same thing, maybe the hurry for publish something.

Awesome experience

This endless hunger for publish or perish is just killing My love for science, today i just wanna enjoy My postdoc and do cool research with my límited skills but with curiosity and kindnes.

Great talk Dr Landry so interesting to read the uncoming papers

En casa esquina hay cajas tiradas. Definitivamente un misterio del siglo XXI

Estar en una relación es construir un mundo, con su propio idioma y hasta con sonidos e imágenes. Que difícil es ponerle punto final. Sólo te deseo paciencia

Tomorrow leg day, today arms and photos

Sometimes I need to remember that life Is not a race even science is just about do what you really love and learn a lot

Thanks sometimes fail teach You Even more than success

That's also my dream

Interested and ready for field work

Is the position still open? 🥺

I'm just reading and trying to find My place in the scientific world
