In a recent Evolutionary Applications paper, Haig et al. (2016) presented an idea for the formation of a National Center for Small Population Biology. The paper was invited as part of a special issue dedicated to women in science (Wellenreuther and Otto 2016) where authors were asked to add a section to their papers that explored the idea of ‘what would you do now in your career if you could do...

Sediment transport, erosion, and deposition are primary drivers of river geomorphic processes ecological services. Suspended-sediment concentration (SSC) is an important parameter for evaluating these accordingly significant interest to engineers, scientists, water resource managers. The United States Geological Survey (USGS) previously operated nine daily SSC gauging stations along the Mississ...

In the history of surveying and mapping, a large volumes of topographic maps and digital elevation models have been created at various scales throughout the world. However, positional errors and geometric distortions may exist in the topographic contour maps and their derived DEMs due to inaccurate ground control and poor navigation techniques in the early years. In this paper, we present a new...

People believe what they can see. The Poles exist as a frozen dream to most people. The International Polar Year wants to break the ice (so to speak), open up the Poles to the general public, support current polar research, and encourage new research projects. The IPY officially begins in March, 2007. As part of this effort, the U.S. Geological Survey (USGS) and the British Antarctic Survey (BA...
