The Nitrogen Cycle Nitrogen is an element that is found in living things like plants and animals, dead things like fallen leaves and dear animals, and non-living things like air and water.

The Nitrogen Cycle Game

The nitrogen cycle is one of the biogeochemical cycles and is very important for ecosystems. Nitrogen cycles slowly, stored in reservoirs such as the atmosphere, living organisms, soils, and oceans along its way. British Columbia's Mountain Pine Beetle.

Joanne Stolen – Summit Daily News The term symbiosis comes from the Ancient Greek “syn” — “with” — and “bíosis” — “living” — and is the close and often long-term interactions between different biological species. Often this interaction is obligate, in that neither can live without the other. One classic example is the lichen, a combination of a fungus and green algae.

New hope for beetle-killed landscapes

Since the 1990s, naturally-occurring bark beetles have multiplied under the effects of drought, climate change and fire-repressed forests, leading to outbreaks that have ravaged forests and left land managers scrambling to deal with a glut of dead trees. But 2015 may prove a turning point. 1981Cole_Some%20Risks%20and%20Causes%20of%20Mort%20in%20MPB.pdf. Rocky-Mountain-Forests-at-Risk-Full-Report.

One chilly morning in October 2013, Diana Six parked her white Subaru at the edge of a pine forest in southwestern Montana’s Big Hole Valley.

Pine Beetle Epidemic

Beneath snow-tipped peaks, lodgepole pines in four different colors draped the hillside—a time line of carnage. The gray ones, now just trunks and branches, had died in 2009. Light red trees, still holding needles, had succumbed in 2011. Darker, auburn trees had perished in 2012. Even the seemingly healthy green trees, said Six, a ponytailed, bodybuilding, beer-brewing entomologist at the University of Montana, were not what they seemed. The Geologic Carbon Cycle.

Gamers Going Green: New Video Game Turns Players Into Biofuel Farmers

These games provide hours upon hours of entertainment for dedicated players, many of whom are enticed by the prospect of hunting zombies and defeating alien empires. But of course, video games aren't just about fun these days. Since the late 1980s, video games have been used as teaching tools in the classroom, at home, and in other informal education settings.

Although there is general agreement that we should be growing crops that can be turned into biofuels, scientists and farmers are still debating the best way to proceed. The fields on the left are populated by corn and switchgrass; at right, graphs show the farm's sustainability over time in terms of ecology, income, and energy production. It doesn’t take long to figure out that maximizing your score isn’t straightforward.

Gorongosa National Park Interactive Map. A partnership between the nonprofit Gorongosa Restoration Project and Mozambique’s government has been instrumental in developing plans to sustain the restoration of Gorongosa National Park after its wildlife was ravaged by a civil war that engulfed the country from 1977 to 1992.

Gorongosa National Park Interactive Map

The restoration effort affords important research opportunities and provides a case study in ecology and conservation science. Use the interactive map to explore the key features of the park’s design, including diverse environments and ecosystems, conservation features, and community and tourism resources that provide opportunities for local residents and incentives for sustaining the environment for future generations. This interactive map was updated in December 2014 to include a past and future view of the park, which show, respectively, how the park boundary has changed over time and the vision for creating a protected corridor linking Gorongosa to a nearby nature reserve.
