Between 1980 and 2004, extreme weather cost the world an estimated US$1.4 trillion and much loss of life. Climate change is expected to exacerbate flooding, drought, and other weather hazards. Population growth in regions expected to be hard hit by extreme weather will expose more people to risk. Communities can take steps to build resiliency, say scientists in a Royal…

On the island nation of Madagascar, the long-limbed local primates, lemurs, are for some trees, essential helpers. It is advantageous for a tree to scatter its progeny not just to the wind and widely, but where they will find fertile ground and clement conditions for growth. Some trees recruit animals for this task by tempting them with delicious and nutritious…

Plant biology PhD student Uma Nagendra of the University of Georgia, Athens, wins the 2014 Dance Your PhD competion, sponsored by Science, AAAS, and HighWire Press. Floating on trapeze wires, young white pine seedlings unfurl and reach for light. But lurking in the roots of the parent tree are dangerous fungi that creep forth to strike at the young scions. The sprouts…

A guest post by Greg Goldsmith, a tropical plant ecologist and part of the multitalented team behind Canopy in the Clouds. He describes methods he used to track and analyze audience engagement in the educational website with colleagues Drew Fulton, Colin Witherill, and Javier Espeleta in an article out today in Ecosphere.

On the tidal mudflats of Georgia and South Carolina, the red Japanese seaweed Gracilaria vermiculophylla is gaining a foothold where no native seaweeds live. Only debris and straggles of dead marsh grass used to break the expanse of mud at low tide. Crabs, shrimp, and small crustaceans mob the seaweed in abundance. What makes it so popular? Not its food…

Ecologists working in central Pennsylvania forests have found that forest top soils capture and stabilize the powerful fertilizer nitrogen quickly, within days, but release it slowly, over years to decades. The discrepancy in rates means that nitrogen can build up in soils, David Lewis, Michael Castellano, and Jason Kaye report in the October 2014 issue of ESA’s journal Ecology, published…

There is water under the dry sands of the Kalahari. Perversely, this gift has lead to a cycle of land degradation.

“When the sun peeped over the Sierra Madre, it slanted across a hundred miles of lovely desolation, a vast flat bowl of wilderness rimmed by jagged peaks. On the map the Delta was bisected by the river, but in fact the river was nowhere and everywhere, for he could not decide which of a hundred green lagoons offered the most pleasant and least speedy path to the Gulf.”

ESA members have elected David Inouye, a plant ecologist and professor emeritus of the Department of Biology at the University of Maryland, College Park, to lead the Society as president of the board of directors for the 2014-15 year. Inouye stepped into the post this August at the 99th Annual Meeting of the Ecological Society. “I’m greatly honored to be…

Can you describe your research with a sketch? What would you draw? Johanna Varner, Erin Gleeson, and Nancy Huntly are passionate about mountain research — and about promoting science communication. They’ve Storified what happened when they roamed the halls at the 2014 Annual Meeting in Sacramento, asking ecologists to #SketchYourScience.

Datasets from long-running volunteer survey programs, calibrated with data from sporadic intensive monitoring efforts, have allowed ecologists to track the recovery of peregrine falcons in California and evaluate the effectiveness of a predictive model popular in the management of threatened species. In recovery from the deadly legacy of DDT, American peregrine falcons (Falco peregrinus anatum) faced new uncertainty in 1992,…

On Monday, ESA’s Natural History Section asked you to tweet your naturalist identity with pride during their #IAmANaturalist campaign, and you obliged, coming through with humor, awe, and humility—sometimes fishy, sometimes muddy, and always with great style. Tweeters shared their love of natural history and testified to how it roots their life and their research, outreach, and education endeavors. We’ve…
