Two high-profile species, Asian carp in the Midwest and Burmese pythons in the Everglades, are the focus of much attention by decision makers, the public and the media. Sharon Gross, Robert Reed and Cynthia Kolar discuss issues related to invasive species and explain innovative methods used to help detect and control these invaders.

The disease is estimated to have killed over five million hibernating bats. An outbreak of infectious disease among bats on the order of white-nose syndrome is without precedent, and although insect-feeding wild bats may lack the easily defined monetary value of domestic animals, a recent analysis showed that they provide natural pest control services to American farmers valued at approximately $23 billion per year. Dr. David Blehert discusses this emergent wildlife disease and the profound impacts white-nose syndrome may have in the 21st century.

Living microorganisms and chemical contaminants such as pesticides and metals are carried along with the dust. What biological and chemical contaminants are hitchhiking with the dust and how might downwind ecosystems such as coral reefs and human health be affected?

]]> <![CDATA[USGS Public Lecture Series: Watching Nature's Clock: A Citizen-Scientist Effort to Track Seasonal Signs of Climate Change]]> http://gallery.usgs.gov/videos/117 A new USGS program, the USA National Phenology Network, is recruiting tens of thousands of volunteers to team up with scientists to help track the effects of climate on seasonal patterns of plant and animal behavior. Come learn how you can contribute to this new national effort, by getting outside, and observing and recording flowering, fruiting and other seasonal events. Scientists and resource managers will use your observations to help track effects of climate change on the Earth's life-support systems.
