Water rises, cattle graze, dunes walk on the Kalahari

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

River Flow By Design: Environmental Flows Support Ecosystem Services In Rivers Natural And Novel

“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.”

Volunteer ‘eyes on the skies’ track peregrine falcon recovery in California

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, when...

In India, vaccination, sterilization of stray dogs curbs rabies better than culls

When people encounter stray dogs in Jaipur, India, they cross the street to put distance between themselves and a potentially deadly bite. Street dogs are endemic in Indian cities and experience has taught citizens caution. The incidence of rabies in the stray population is uncomfortably high, resulting in about 20,000 human cases every year. Most cities have tried to solve the problem by killing the dogs, but a few communities are...

History of fire and drought shapes the ecology of California, past and future

Fire season has arrived in California with vengeance in this third year of extended drought for the state. A series of large fires east of Redding and Fresno, in Yosemite, and on the Oregon border prompted Gov. Jerry Brown to declare a state of emergency on Sunday, August 3rd. As force of destruction and renewal, fire has a long and intimate history with the ecology of California. Ecological scientists will discuss aspects of that...

The Rim Fire one year later: a natural experiment in fire ecology and management

The enormous conflagration known as the Rim Fire was in full fury, raging swiftly from crown to crown among mature trees, when it entered the backcountry of Yosemite National Park in California’s Sierra Nevada in late August 2013. But inside the park, the battle began to turn, enacting a case study in the way management decisions and drought can combine to fuel large, severe fires.

Fish biodiversity protects coral reefs

Science Bulletins: Fish Biodiversity Protects Coral Reefs from AMNH on Vimeo. In tropical coral reefs, plant-eating fish and other herbivores support the dominance of the living coral by eating seaweed. Also known as macro algae, seaweeds create energy from sunlight through photosynthesis, like plants, and support much of the life in the sea. But they also compete with young corals for space, and with the photosynthesizing...
