Conservationist's Perspective on Amphibian Declines - Globally and Locally
Brian Gratwicke, a conservation biologist who leads the amphibian conservation programs at the Smithsonian’s National Zoo and Conservation Biology Institute, will talk about his global work and then bring it home to local amphibians, including hellbenders and redback salamanders, and vernal pools.
Brian’s focus is building capacity to conserve amphibians in Appalachia and Panama, developing outreach and educational programs and exhibits to build public support for amphibian conservation, and research to develop tools to reintroduce amphibians back into the wild.
One major research focus is developing applied solutions for the amphibian chytrid fungus, including research into the area of beneficial skin bacteria and identifying genetic traits associated with resistance to the disease. He also conducts research into emerging diseases and the effects of climate change on Appalachian salamanders.
Gratwicke grew up in Zimbabwe and began his conservation work researching the impacts to freshwater fish in Africa. In 2000, he was awarded a Rhodes scholarship that took him to Oxford, where he studied marine fish communities in the British Virgin Islands for his doctorate. After completing his doctorate, Gratwicke moved to Washington, D.C., where he worked as a program administrator and then assistant director of the National Fish and Wildlife Foundation’s Save the Tiger Fund.

Forest Fire Management in Maryland

The Maryland Forest Service manages over 214,000 acres of designated State Forest. Those management efforts include preventing unwanted forest fires AND overseeing prescribed burns in forests to restore and maintain ecosystems. It may seem counterintuitive, but fire is part of the natural cycle of forest growth and development. In fact, some trees, like the pitch and table mountain pines, are f...

    Theory: maybe the ,"Ancient One's", of the now ,"America's",have always been the true native peoples. Instead of coming from another land, they could have populated near the coastlines of America's. As the water rose they moved inland and that's why all artifacts date back to a similar time.Well the same time at numerous locations around the America's which would be impossible if people's traveled from the same route to inhabit the America's.

    The best understanding of the fluted 'notch' on the Clovis type point: it's formed to assist in the hafting (securing) of the blade onto the split (& shaped) end of a spear. This was accomplished by using thin cordage in conjunction with natural adhesives (tree resins). p.s. big fan of Dr Jessi Halligan ~

    The "3 species of tyrant" bit really gets at something. People want to name things - make their mark, so to speak. Given that we live on average 80 years, trying to define an animal that, in some form, existed for 25 thousand times that long (assuming T-rex lasted 2 million years)........obviously there's going to be some change there. I know that cladistics is the "best fit" solution we have for understanding what we discover, and that's very useful for describing things. I wish more researchers and scientists would point out that every little thing we get is just a snapshot, with millions of years before and after missing. People can't even agree on speciation with extant animals, within their own lifetime. Maybe we need a different framework for extinct animals? It just seems somewhat broken. Why are we expending brain-power trying to differentiate slow species progression.....instead of evaluating, over time, with the snapshots we get, what was successful, what failed, what lasted, what didn't? I guess I know the answer: You don't get to name anything if you do research like that. Still, I'd love to see it.

    what a great presentation. I am on the Board of a Museum that owns about 2,000 points. I know that there were 2 points documented years ago as being paleo-Indian points but they were either lent out and never returned or lost somewhere in the collection. Now I have a better idea of what I'm looking for. Much easier to look for fluting than looking at them with a ruler and comparing them to two crummy photos I have from an archaeological journal.

    Learning about the Geology of the US East Coast and the Appalachian Mountains is my passion! I cannot stop learning about it. I am so interested in plate tectonics. More specifically, the Wilson Cycle and how it shaped the Appalachian Mountains. I am fascinated how this same cycle of oceans closing, orogenic events, and subsequent rifting occurs over billions of years. I am very interested in the details of how convergent plate boundaries transition to rifting. And how a pristine ocean like the Atlantic, possibly forms subduction zones in the future to complete the Wilson cycle. I am also interested in why this cycle seems to repeat over and over again with the same land masses (generally speaking).
