Madhusudan Katti won this year’s ESA Science Café Prize with his lyric contemplation of the wildlife living alongside us in urban spaces, and the necessary participation of cities in the future of biodiversity on planet earth. Katti is a professor at California State University Fresno and records occasional radio essays for Valley Public Radio. He tweets prolifically as @leafwarbler and blogs at Reconciliation Ecology.

Risk analysis finds savings for homeowners and local governments of excluding invasive pests like the emerald ash borer outweigh added cost to imported goods.

Me and milkweed fruit – my #NatureSelfie for #EarthDay. Nash Turley, a naturalist, photographer, musician, and PhD student in evolutionary ecology at the University of Toronto, snapped this shot in Ithaca, NY, in 2011. He tweeted, “Everyday is Earth Day; the fact that the calendar says today is ‘Earth Day’ doesn’t really mean anything to me. Sort of like how aboriginal cultures don’t have a word for ‘nature’ because they didn’t see themselves as separate from nature….the fact that we have a day for the Earth shows how disconnected modern societies are from ‘nature’.”
Earth Day started as a grassroots protest movement in 1970 and has solidified into an annual event. What does Earth Day mean in 2014?
Like gyms or bars, lekking grounds are social performance spaces, where males spread their tail-feathers, inflate their impressive chests, and strut about, calling amorously to the lady birds. Ecologist Gail Patricelli of UC Davis captured this video of a lek near Hudson, Wyoming. US Fish and Wildlife Service named the grouse’s habitat, the Great Plains sage-steppe, one of the most imperiled ecosystems in America.
Wildfire is the predominant cause of habitat loss in the Great Basin. Reseeding burned land to stabilize soils has not restored sagebrush habitat for the endangered greater sage grouse, according to a report in the journal Ecosphere. The US Fish and Wildlife Service is considering protecting the grouse under the Endangered Species act, which could affect the management of 250,000 square miles of land in the western US.
The Strawberry poison frog lavishes care upon its offspring. It’s just that kind of frog. In the March issue of Ecology, Stynoski et al. report that it also feeds its progeny poison. Also in this issue: P value debates, arctic warming, and estimating the success of biological invasions.
