Eight hundred years ago, relatively small armies of mounted warriors suddenly exploded outward from the cold, arid high-elevation grasslands of Mongolia and reshaped world geography, culture and history in ways that still resound today. How did they do it?

This week in PLoS One, a group of researchers coordinated by the International Union for Conservation of Nature (IUCN), published a new framework for assessing threats to ecosystems. This study offers the theoretical foundation for the Red List criteria for ecosystems, which like its predecessor, the Species Red List, will aim to inform government and society about the current status of biodiversity and provide the data necessary to develop strategies and priorities for conservation.

Mysterious Honeybee Deaths Remain Unsolved

Since 2006, millions of bees have been dying in a phenomenon known as colony collapse disorder. There are now 2.5 million honeybee colonies in the United States, down from 6 million several decades ago. Photo Credit: Steve Evans

According to a comprehensive federal study, the collapse of American honeybee colonies stems from a complex slew of factors, including pesticides, parasites, poor nutrition and a lack of genetic diversity.

“You can do math on excel?” I ask. I immediately imagine a face-palm response, but Dario, one of my advisors, is nice enough to hide it. I’ve collected tree core samples, I’ve prepared them and cross-dated them. Now what? Oh, right. The Science.

“Are you using this idea for your thesis research?”

I heard this as I stood in front of a classroom full of old-growth forest ecology students. The question had come from Neil Pederson, who was sitting directly in front of me. He was asking this question because I had just spent the past 12 minutes discussing the intricacies of land snail biology and ecology that would make them great organisms to use for ecological modeling in regards to disturbance.
