A small experiment using sleights of hand and illusions offers insights into how birds and people perceive the world.
The coin is in the illusionist’s left hand, now it’s in the right — or is it? Sleight of hand tricks are old standbys for magicians, street performers and people who’ve had a little too much to drink at parties. Continue reading
Our practice was born in Costa Rica, so we sometimes may appear partisan when it comes to celebrating the sciences related to biodiversity. Costa Rica has impressive credentials in that realm, especially relative to its size as a country. But we are very clear on the fact that it would take dozens of Costa Rica-sized biodiversity hotspots to match the scale of the Amazon region, and it is no surprise that studies like those of these scholars are carried out with Amazonian data:
“Most evolutionary research focuses on how new species form. But we want to understand how whole ecosystems evolve,” said Alexandre Antonelli.

A recent study says that many of the plants and animals that call Latin America home may have had their roots in the Amazon region.
The study, co-authored by Harvard Visiting Scholar Alexandre Antonelli and an international team of researchers, says that a dynamic process of colonization and speciation led to the formation of the American tropics, which is the most species-rich region on the planet. The study is described in a paper published in the Proceedings of the National Academy of Sciences.
“We were astonished to detect so much movement across such different environments and over such large distances,” said Antonelli, the study’s lead author. “Up until now, these natural dispersal events were assumed to be quite rare. Our results show how crucial these events have been in the formation of tropical America’s unique and outstandingly rich biodiversity.” Continue reading

We had a long run of links since 2011 to her wondrous science reporting, and then we had not seen her since this past September; suddenly she has come back on our radar, unexpectedly but predictably awesome:
Whether personally or professionally, Daniel Kronauer of Rockefeller University is the sort of biologist who leaves no stone unturned. Passionate about ants and other insects since kindergarten, Dr. Kronauer says he still loves flipping over rocks “just to see what’s crawling around underneath.”. Continue reading
