Assessing Sandhill Crane Roosting Habitat along the Platte River, Nebraska

Each spring approximately 500,000 sandhill cranes and some endangered whooping cranes use the Central Platte River Valley in Nebraska as a staging habitat during their migration north to breeding and nesting grounds in Canada, Alaska, and the Siberian Arctic. Over the last century changes in the flow of the river have altered the river channels and the distribution of roost sites. USGS researchers studied linkages between water flow, sediment supply, channel morphology, and preferred sites for crane roosting. These results are useful for estimating crane populations and for providing resource managers with techniques to understand crane habitats.

AN ANALYSIS OF SMALL BUSINESS LOAN GUARANTEE FUNDS

Small businesses are considered important engines for job growth and economic development by policy makers worldwide. One of the most commonly cited constraints of small businesses is a lack of access to capital. To address this constraint, small business loan guarantee programs have been established in over 100 countries. There are a variety of types of guarantee funds, with the most significant differences being which borrowers are eligible for guarantees, and how borrowers are approved for guarantees. There is currently no clear delineation between types of programs and the economic conditions they operate in, though some trends are becoming apparent. However, these trends may not be leading to the best economic outcomes possible. By better matching the structure of the guarantee fund to the economic conditions it operates in, the program’s success in meeting economic development goals may be greatly improved. Many programs in developing countries may not be taking advantage of bank expertise and may be limiting the scope of their effectiveness. At the same time, programs in developed countries may be wasting resources by scattering their efforts too thinly and subsidizing less competitive firms to the detriment of local economic development.

Notes on Microtine Rodents from the Brooks Range, Arctic Alaska

In connection with parasitological studies carried on during 1949 for the U.S. Public Health Service, the writer collected a considerable number of mammals from the northern edge of the "Endicott" section of the Brooks Range, in Arctic Alaska. The mammalian fauna of this region is poorly known, since apparently no previous collecting has been done here. About 200 microtine rodents were collected, mostly near Tolugak Lake (latitude 68° 24' N, longitude 151° 26' W), near the head of the Anaktuvuk River Valley. A few specimens were also taken at Umiat, on the Colville River, about 80 miles north of Tolugak Lake (latitude 69° 23' N, longitude 152° 10' W). Five species are represented: Clethrionomys rutilis dawsoni (Merriam), Microtus oeconomus macfarlani Merriam, Microtus miurus paneaki, n. subsp., Lemmus trimucronatus alascensis Merriam and Dicrostonyx groenlandicus rubricatus (Richardson). More complete details concerning their ecology and reproduction will be presented in a later paper, at which time the other mammals obtained will also be considered. The specimens have been deposited in the U.S. National Museum.

Regulating Green Buildings

Green buildings are becoming the new fixation for the building industry because of the impact they have on the carbon footprint and the cost savings they offer for utility costs. Governments have begun to produce policies and regulations that implement and mandate green buildings due to these successes. However, the policies are having troubles increasing the popularity and quantities of green buildings. There is a need for a way to produce better policies and regulations that will increase both the amount of green buildings their popularity. A decision-making tool, such as a decision tree, should be created to help policymakers who do not have the backgrounds to produce well thought out regulations. By researching the green building industry and its current status, key points can be graphed out in a decision tool that will provide the needed education for policy makers to produce better green building regulations.
