Climate warming may not drive net losses of soil carbon from tropical forests
July 23, 2014 12:16 PM - Carnegie Institute for Science

The planet's soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. This enormous release of carbon is balanced by carbon coming into the soil system from falling leaves and other plant matter, as well as by the underground activities of plant roots.

Goats to the Rescue in Fire-Prone Bay Area
June 3, 2014 02:47 PM - S.E. Smith, Care2

How does the saying go? Only you can prevent forest fires, or only goats can prevent forest fires? You'll understand the confusion when you meet the Bay Area's latest fire prevention crews: goats. California is facing a forecast for what may be the worst fire season ever, thanks to drought conditions and a large buildup of tinder. Fire management professionals are working ahead of time to try to clear brush, high grass and other fire hazards, in the hopes of reducing the spread of the inevitable wildfires that are already streaking across the state. When it comes to brush clearance crews, it can be tough to find someone willing to do the job. It's backbreaking labor conducted in the hot sun, and it takes hours to make a dent in overgrown shrubs and brush, which are often filled with tangles of thorns and other unpleasant surprises. Brush clearance can get extremely expensive, and it requires constant maintenance. That's one reason why people have been turning to rental goats to clear brush and keep areas like road verges, medians and hillsides trimmed.

How forest debris affects freshwater food chains

Allison Winter, ENN
While one may think that forest and lake ecosystems are two separate networks, new research shows how forest debris is an important contributor to freshwater food chains. How? Debris in the form of organic carbon from trees washes into freshwater lakes, which consequently supplements the diets of microscopic zooplankton and the fish that feed on them. Researchers at the University of Cambridge conducted a study at Daisy Lake in Ontario, Canadian by observing Yellow Perch fish from different parts of the water body with varying degrees of surrounding forest cover. Carbon from forest debris has a different elemental mass than carbon produced by algae in the aquatic food chain. By analyzing the young Perch that had been born that year, scientists were able to determine that at least 34% of the fish biomass comes from vegetation, increasing to 66% in areas surrounded by rich forest. Essentially, the more forest around the edge of the lake, the fatter the fish in that part of the lake were. Similarly, the sparser the forest leaves, the smaller the fish.

Dandelion Salad, Anyone?

July 22nd, 2014
Yes, dandelion salad is a real thing, not just a made up salad that kids make while playing pretend in the back yard. In fact, many commonly found plants are actually edible, including dandelions. I thought it would be fun to include some easily found leafy appetizers for ENN users to experiment with. Of course, not all plants are edible, so it is important to correctly identify a plant before trying to eat it.

Are You Smarter Than A Trash Can?

July 12th, 2014
Walking through Boston earlier this week I came across an unusually large trash receptacle. When I went closer to inspect it (throw out my trash) I noticed that it was compactor designed for sustainability.  Besides having a function to compact the trash which would require less pickups, the cans also had solar panels to be [...]
