Historically, more than 90 million acres of what is now the southeastern United States were covered by longleaf pine (Pinus palustris) savanna; today, only 3.4 million acres remain and most are fragmented and in poor condition. Scattered from Virginia in the north to the Florida peninsula in the south and Texas in the west, longleaf pine forests are some of the world’s most biologically diverse ecosystems, and provide critical habitat for 29 threatened and endangered species, including the gopher tortoise (Gopherus polyphemus).

Un equipo de investigadores estadounidenses y chinos ha revelado el color y el diseño de las plumas de Microraptor, un dinosaurio de cuatro alas, del tamaño de una paloma, que vivió hace unos 130 millones de años.

Los hallazgos, que sugieren la importancia de la exhibición en la evolución temprana de las plumas, han sido publicados en la revista ‘Science’. Leer más.

The snake on her property would reveal to biologists a totally new behavior in the invasive snakes wreaking havoc in the Everglades ecosystem. Leer más.
