Hola todos, a propósito del Global Big Day les cuento que hay web genial llamada ExplorAves de la National Audubon Society donde se pueden consultar rastreos de varias aves migratorias que transitan entre Norteamérica y Suramérica 🌎🐦
Y entre los recursos de la página se pueden apreciar animaciones de trayectos migratorios como el que se muestra aquí del Contopus cooperi (Pibí Boreal o Atrapamoscas boreal)👌. Este pequeño pajarito viene desde Alaska hasta el trópico cuando es invierno y se regresa al norte en verano realizando además uno de los recorridos más extensos de este tipo de especies en el continente 😮
Enlace a esta web y otras sobre distribución de especies en https://t.co/nZbSCmhzlL

🧬Cool paper on the evolution of water lilies.🌺
What I liked most was how they adapted to aquatic life. The authors found 481 genes that water lilies have lost, including:
Genes involved in cell wall development — On land, plants need strong tissues to stand upright. In water, buoyancy helps support them, so some of these genes became less necessary.
Immune defense genes — Some land pathogens don’t survive in water, so water lilies likely needed fewer resistance genes.
Genes involved in toxin metabolism — On land, toxins help plants defend themselves. In water, the threats are different, so some of these genes became less necessary.

In 1998, I talked to Craig Venter about the feasibility of sequencing the human genome as a whole-genome shotgun project. Here's a story about that conversation https://t.co/ci0kyDHf43

Kudos!! to @Connie_Bolte for leading a tour-de-force describing one of our favorite hybrid zones - providing foundational methods in demographic modeling and an understanding of neutral processes influencing hybrid zone formation across space and time. https://t.co/7MoHsQBtBU
