What are the big ecological innovations of the last century? #ESA100

In December 2015, the Ecological Society of America will celebrate a big birthday: 100 years since the first group of botanists and zoologists, parasitologists, geologists, physiologists, and marine biologists gathered in Columbus, Ohio, to unite their shared interest in the relationships of the great diversity of living organisms to each other and their surroundings. To kick off our centennial year,…

When polar bears (Ursus maritimus) meet glaucous gulls (Larus hyperboreaus) over the remains of a bowhead whale (Balaena mysticetus), they may be sharing more than a meal. As the warming climate brings animals into new proximity, parasites, viruses, and bacteria can find opportunities to spread to new and naïve hosts, sometimes jumping from birds to mammals, and from marine ecosystems to land ecosystems.

New diseases travel on the wings of birds in a rapidly changing north

When wild birds are a big part of your diet, opening a freshly shot bird to find worms squirming around under the skin is a disconcerting sight. That was exactly what Victoria Kotongan saw in October, 2012, when she set to cleaning two of four spruce grouse (Falcipennis canadensis) she had taken near her home in Unalakleet, on the northwest…

Resilience to Extreme Weather Royal Society Report Executive Summary

Building resillience to extreme weather

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…

‘Threatened’ listing for Gunnison sage grouse rouses political scuffle

  A pair of Gunnison sage grouse. Credit/US Fish and Wildlife Service The recent US Fish and Wildlife Service (FWS) decision to list the Gunnison sage grouse (Centrocercus minimus) as “threatened” under the Endangered Species Act (ESA) has ignited a political fervor between the administration, environmentalists and Colorado and Utah policymakers. “While many people hoped that the extraordinary conservation efforts by our…

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…

Forest dance on wires depicts a creeping fungal multitude blown back by a tornado

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…

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…

The tall, mature trees of a late-succession forest (right) stand next to the young regrowth of a clear-cut forest in central Pennsylvania. The deeper volume of organic matter on the floor of a mature forest can capture more of the nutrient nitrogen when it enters the forest than the clear-cut can. Credit, David Lewis.

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…
