Termites, as ecosystem engineers, modulate the availability of resources for other species, such as soil macro- and microfauna and microorganisms, and create habitats that can be used by a remarkable number of organisms for nesting, roosting or accommodating stages of their life cycles

USGS Ecosystems Mission Area (the biological research arm of the Department of the Interior (DOI), provides science to help America achieve sustainable management and conservation of its biological resources. This work is done within the broader mission of the USGS to serve the Nation with science that advances understanding of our natural resources)

Valley of Death - Brazil.

Cubatao in Brazil was notorious for lethally high levels of air pollution, which led to malformations in newborn babies and widespread health problems.

But by the early 1990s, the city known as the "Valley of Death" had fought back, cutting pollution levels by 90%.

However, Cubatao is still among the most polluted cities in the region, and must work hard to maintain cleaner air.

How Brazil's 'Valley of Death' fought back

Cubatao in Brazil was notorious for high levels of air pollution, but it turned things around.

Wet Tropics of Queensland (stretches along the northeast coast of Australia for some 450 kilometres. Encompassing some 894,420 hectares of mostly tropical rainforest, this stunningly beautiful area is extremely important for its rich and unique biodiversity. It also presents an unparalleled record of the ecological and evolutionary processes that shaped the flora and fauna of Australia, containing the relicts of the great Gondwanan forest that covered Australia and part of Antarctica 50 to 100 million years ago. All of Australia’s unique marsupials and most of its other animals originated in rainforest ecosystems, and their closest surviving relatives occur in the Wet Tropics. These living relicts of the Gondwanan era and their subsequent diversification provide unique insights to the process of evolution in general. They also provide important information for the interpretation of fossils of plants and animals found elsewhere in Australia, and about the evolution of Australia’s sclerophyll flora and marsupial fauna in particular)

Bracken (Pteridium) holds a pivotal role in succession, usually occurring in sequence between plagio-climax  communities such as heathland and woodland. It is at this interface that bracken causes problems for man, as the sub-seral communities are more valuable for agricultural use and most have a greater conservation value than bracken-dominated ones (there are a few exceptions).

Cedar Creek Ecosystem Science Reserve (is an ecological research site located primarily in East Bethel, Minnesota in the counties of Anoka and Isanti on the northern edge of the Minneapolis-Saint Paul metropolitan area. Encompassing 5,400 acres of native upland forests and prairie and lowland swamps and meadows, the site contains over 900 plots of long-term experimental research which evaluate plant competition and biodiversity. The herbivory research division examines animal and plant relationships. Led by prominent American ecologist G. David Tilman, the University schedules more than 130 faculty, post-doctoral researchers, graduate students, staff, and undergraduate researcher interns to the site as of 2006)
