Highlights From The October 2014 Issue Of The Ecological Society Of America\u2019s Journal Ecology<\/em>, Published Online Today.<\/strong> Invasive seaweed shelters native crustacean<\/strong>: On the tidal mudflats of Georgia and South Carolina, the red Japanese seaweed Gracilaria vermiculophylla<\/em> 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., Wright and colleagues found that the tiny native crustaceanGammarus<\/a> mucronatus<\/em> (one of the 9,500 species of amphipod, which includes sand fleas) does not eat much of the seaweed. Rather, its attraction is structural. The seaweed protects the small crustaceans from predators at high tide and from the dry heat of the flats at low tide. G. mucronatus<\/em>was up to 100 times as abundant on seaweed invaded mudflats. Mature forests store nitrogen in soils<\/strong>: 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. Forests may be providing an unappreciated service by storing excess nitrogen emitted by modern agriculture, industry, and transport before it can cause problems for our waterways.

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.

Charcoaling manure and greening neighborhoods: ecological approaches to cleaner water in the Chesapeake Bay Watershed.<\/h3>\nWhen ecologists gather in Baltimore, Md., this August for the 100th<\/sup> Annual Meeting of the Ecological Society of America, special attention will fall on the local Chesapeake Bay watershed, with field trips and research presentations exploring its rich wildlife and social history. At symposia, poster exhibits, and site visits, ecologists will have opportunities to discuss the latest research and experiences working with stakeholders in the region to improve the health of the nation\u2019s largest estuary.
