Madagascar team tracks lemurs as they spread the seeds of the rainforest

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 fruits – inside which hide seeds sealed in hard, indigestible coats for...

Invasive seaweed shelters tiny native critters on Georgia mudflats

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 value. On mudflats near Savannah, Ga., Jeffrey Wright and colleagues found that...

Old forests store new nitrogen–and may soak up nutrient excesses

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 online this week. Forests may be...

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...
