Science Nation - Removing Dams

submitted by: nsf
There's been a lot of research on what happens to a river when dams go up, but what happens when the dam comes down? With support from the National Science Foundation, Dartmouth College geographer Frank Magilligan is researching the impact of dam removal. His lab has been the relatively small Homestead Dam, built more than 200 years ago along the Ashuelot River in New Hampshire. He and his team have collected data on the ecology and geology of the Ashuelot River both before and after the Dam...

The Granite Mountains of the Mojave Desert are a hot and arid ecosystem in July, but plants and animals thrive in this heat. Mojave rattlesnakes, lizards, hummingbirds, ants, and grasshoppers are just a few of the amazing species we found here.

Evolution of Reproductive Morphology in Leaf Endophytes

submitted by: JeffreyTownsend
The endophytic lifestyle has played an important role in the evolution of the morphology of reproductive structures (body) in one of the most problematic groups in fungal classification, the Leotiomycetes (Ascomycota). Mapping fungal morphologies to two groups in the Leiotiomycetes, the Rhytismatales and Hemiphacidiaceae reveals significant divergence in body size, shape and complexity. Mapping ecological roles to these taxa reveals that the groups include endophytic fungi living on leaves...

Getting Started with Ecological Metadata Language - Using Morpho

submitted by: LTER_NetworkOffice_is

You want to create a metadata record that describes your Ecological Data set. You want this metadata document to be standardized for easy sharing - and you thought that you would use the Ecological Metadata Language (EML). One way to create EML records is using Morpho. Morphos is free, download it from the "ecoinformatics.org" site and use this video-tutorial to see how you can use Morpho.
