As the human population inexorably grows, its cumulative
impacts on the earth’s resources are hard to ignore.
The ability of the earth to support more humans is
dependent on the ability of humans to manage natural
resources wisely. Because disturbance alters resource
levels, effective management requires understanding of
the ecology of disturbance. Editorship of this book was
undertaken with several goals in mind. First, I wanted
to present an organized summary of the many types
of disturbances that impact the earth, with as global
a focus as the existing literature allowed....
Aboveground and Belowground Consequences of Long-Term Forest Retrogression in the Timeframe of Millennia and Beyond
Following the occurrence of a substantial disturbance and creation of a new surface, primary succession occurs. This involves colonisation by new plant species, and their associated aboveground and belowground biota.

The car sequencing problem is a widespread short-term decision problem, in which
sequences of diﬀerent car models launched down a mixed-model assembly line are to
be determined. To avoid work overloads of workforce, car sequencing restricts the
maximum occurrence of labor-intensive options, e.g., a sunroof, in a subsequence of
a certain length by applying sequencing rules. Existing research invariably assumes
that the model sequence can be planned with all degrees of freedom.
This, too, was the period when the integrity of Eclectic Medicines was
threatened by the “resinoid” distraction, with which dishonest
manufacturers came near disrupting Eclecticism. Finally, there arose a
fierce war against Professor L. E. Jones (conducted most largely upon
paper) which displayed to full advantage the ridiculous frailties of all
concerned. Another disturber was to come.
Global warming and changes in climate have already had observed impacts on natural
ecosystems and species. Natural systems such as wetlands, mangroves, coral reefs, cloud
forests, Arctic and high latitude ecosystems are especially vulnerable to climate‐induced
disturbances. Enhanced protection and management of biological resources and habitats can
mitigate impacts and contribute to solutions as nations and communities strive to adapt to
climate change. Biodiversity is the foundation and mainstay of agriculture, forests, and fisheries.
rock wall stands on a forest floor in New England. This wall was built
when the United States was a young nation, by human hands. Between its
origin (circa 1800) and now, there have been shifts in this scene – some
marked, some less apparent.
On both sides of the wall, a second-growth forest stands, having replaced
virgin woods, removed in all likelihood well before the fence was put in place.
On the boulders comprising the fence, lichen colonies have formed, a phenomenon
requiring decades without disturbance. This structure likely used to mark the
edge of a farm...
