Megafauna loss reshaped Panama’s ecosystems. Our new study (led by @felix-pym.bsky.social) traces late Pleistocene declines on the Isthmus and highlights key lessons for trophic rewilding in the Neotropics. Check it out! doi.org/10.1016/j.qu...

Whatever you might think of Maduro, the seizure and kidnapping of a head of state takes us to a very dark place. Vast, arbitrary, extra-legal power, which could be exercised almost anywhere, regardless of the character of the target government.

Vcs sabiam que, considerando-se que o Bolsonaro dê um soluço a cada segundo, se ele der um soluço para cada pessoa que morreu de Covid na pandemia, ele precisará de 22 anos soluçando dia e noite para completar essa tarefa?

⛏️💧🌽Contradictory to previous theories, a pre-Columbian society in the Amazon developed a sophisticated agricultural engineering system that allowed them to produce maize throughout the year, according to a new ICTA-UAB research led by @umbamoxos.bsky.social ⁠ Video 🎥 www.youtube.com/watch?v=NdV-...

Our latest study, published in Nature and led by @umbamoxos.bsky.social, describes how the pre-Hispanic Casarabe Society of the Llanos de Moxos in Bolivia designed and implemented an innovative landscape engineering system. Read more about here: www.nature.com/articles/s41...
