The skeleton of Megatherium, as figured in William Buckland's Geology and Mineralogy Considered With Reference to Natural Theology. There is something fantastically weird about giant ground sloths. Creatures from a not-too-distant past, close enough in time that their hair and hide is sometimes found in circumstances of exceptional preservation, these creatures have no living equivalent. Their arboreal cousins still live in the tropics of the western hemisphere, but they can hardly be considered proxies for the ground sloths of the Pleistocene. The most famous of these ancient beasts was…
NPR reports on the discovery of a bee that builds tiny, multi-coloured nests out of flower petals. The rare solitary bee Osmia avoseta creates the cocoons out of a mixture of mud, flower petals and nectar. Each case holds a single egg. The discovery by a group of scientists in Turkey co-incided with that of another team in Iran; the two groups published their findings together in the American Museum Novitae. More pictures and info on NPR.org.

From the "I-never-thought-I'd-use-this-class" file, I took a semester course once from an oil spill expert. Professor Ed Gilfillan had studied the response of Prince William Sound to various clean-up regimens following the wreck of the Exxon Valdez, and we spent weeks learning about chemistry of oil spills and the factors involved in ecological recovery. The class was over 15 years ago, mind you, and in retrospect I remember only two things. But these are two very key things, and they are both relevant to the ongoing tragedy in the Gulf of Mexico. 1. The soil structure at the coastline will…

What was that inexplicable bit of chitin hiding away in a hole in a twig? This photo should help: It's the heavily sclerotized head shield of a Cephalotes varians turtle ant. Ants in this mostly Neotropical genus inhabit pre-existing cavities in trees and branches, a limiting resource that spurs intense competition among colonies of various tree-dwelling species. Workers come in two size classes: small and relatively lithe, and tank-like with a dinner plate for a head. Turtle ants aren't fighters. Rather, they're all about defense. If a colony gets hold of an old beetle burrow, the heavily…
News from NESCent - Craig MccLain of the Deep Sea News fame just had a paper published. This is the video that explains what that is all about: Also read the press release. And the reference is: McClain, C. and J. P. Barry (2010). "Habitat heterogeneity, biogenic disturbance, and resource availability work in concert to regulate biodiversity in deep submarine canyons." Ecology. Related: Deep sea paradox: little food, tons of lifeCraig McClain talk at Sigma Xi

I'm a day late with Nate Hagen's piece, but I just have to link here - it has a beauty and elegance I really admire, and Id do wish him the very best of luck in his new venture. In fact, I'm starting to think that maybe I can cash in too! OK - here it is in a nutshell - though I used to think the main problem with economic theory was that it ignored biology on the demand side and ecology on the supply side, I now see the reality is that neither biology nor ecology has incorporated enough economic theory. Basically, my efforts at falsification of positive economics even down to the day to day…

When we think of our planet's water, we usually think of the vast saltwater oceans that contain 97 percent of it. But the other three percent is equally important to ecosystems and to life as we know it: freshwater found above ground in lakes, rivers, and ponds, and underground in aquifers and streams. World Water Day was designated by the U.N. General Assembly in 1992 to call attention to issues surrounding freshwater around the globe. This year, with the theme "Clean Water for a Healthy World," World Water Day organizers hope to bring the concepts of wastewater management and water…
