Scientists have found the first clear example of how climate extremes, such as the increased frequency of droughts and floods expected with global warming, can create conditions in which diseases that are tolerated individually may converge and cause mass die-offs of livestock or wildlife.
Database Shows Effects Of Acid Rain On Microorganisms In Adirondack Lakes

Researchers have long known that acid rain can severely decrease the diversity of plant and animal communities in fresh water lakes and ponds. However, little is known about how microscopic bacteria, which form the foundation of freshwater ecosystems, respond to acidification.
Abandoned Farmlands Are Key To Sustainable Bioenergy

Biofuels can be a sustainable part of the world's energy future, especially if bioenergy agriculture is developed on currently abandoned or degraded agricultural lands. Using these lands for energy crops, instead of converting existing croplands or clearing new land, avoids competition with food production and preserves carbon-storing forests needed to mitigate climate change.
Dry Tortugas Show Positive Trends: Protected Area Slowly Rebounding

Thirty-eight research divers recently completed a successful 20-day biennial census to measure how the protected status of the Florida Keys National Marine Sanctuary's Tortugas Ecological Reserve and Dry Tortugas National Park's Research Natural Area are helping the regional ecosystem rebound from decades of overfishing and environmental changes.
Exploited Fish Make Rapid Comeback In World's Largest No-take Marine Reserve Network

No-take marine reserves, in which fishing is completely banned, can lead to very rapid comebacks of the fish species most prized by commercial and recreational fisheries, reveals a new study of Australia's Great Barrier Reef.
Reliance On Unverifiable Observations Hinders Successful Conservation Of Wildlife Species
18:39 23-06-2008; source: www.sciencedaily.com
Researchers from the US Forest Service's Pacific Northwest and Rocky Mountain Research Stations examined three cases of biological misunderstandings in which unverifiable, anecdotal observations were accepted as empirical evidence. Ultimately, they found that this acceptance adversely affected conservation goals for the fisher in the Pacific states, the wolverine in California, and the ivory-billed woodpecker in the southeast by vastly overestimating their range and abundance. The researchers' findings appear in the current issue of the journal BioScience.

There is no fate that cannot be surmounted by scorn.
We have left undone those things which we ought to have done; and we have done those things which we ought not to have done.
In anger we should refrain both from speech and action.
