How many trees are there in the Amazon?

A couple of weeks ago some colleagues and I wrote a paper in Science reporting some new findings on Amazonian forests. Some of the findings are actually just numbers, and one of those numbers is really big. It's the number of trees we think probably grow in the Amazon, and it's 390 billion.

The Trilobite Paradoxides

The fossils of a large trilobite called Paradoxides are found in North America, Europe, and Africa, They crawled along the seafloor during the Cambrian Period, 510 million years ago, but not off the coast of North America or Europe. They lived in the shallow waters off the coast of a small continent that no longer exists called Avalonia by geologists.


New spider reminds us: it's still a big world

It was exciting in recent days to see the news about the discovery of a new family of spiders, in a cave in Oregon. New species are found all the time, especially among the arthropods. But a new family is a big deal. It means that an animal is different in very significant ways from others of its kind, the way owls are different from other birds, or bears from other mammals. And while new families of spiders get do designated from time to time in the course of taxonomic revisions, a new spider family has not been discovered in nature since the 1890s.

Science at FMNH : Ep. 13 - The Geologic Record & Environmental Change

The environment in which we live is not static, and the 4.6 billion years of Earth history are a history of change.  Scientists in the Geology Department use cutting edge research to understand the formation of the solar system and the evolution of life on an ever-changing Earth.  

Walking through the public museum (chewing lice and sucking lice)

One thing about walking through the public exhibit areas is that you never know what you will overhear.  OK, sometimes you hear things you don’t want to hear, but just as often, good things get your attention.  I am not making up what I heard the other day on the way into the Fish Division. From behind me, I heard a guy say “look, chewing lice and sucking lice!”
