Bullets, Shrapnel, Case, and Canister: Archeology and GIS at the Piper Farm (Recording Unavailable)
-
Union and Confederate forces fought at Antietam Creek near Sharpsburg, Maryland, on September 17, 1862. It was the bloodiest single-day battle in American military history with nearly 23,000 dead, wounded, and missing. Some of the fiercest fighting occurred around the Sunken Road -- the northern boundary of the Henry Piper farm. Over four field seasons, archaeologists conducted systematic metal-detector surveys of the Piper Orchard, site of the Confederates’ retreat from the Sunken Road and their stand to hold the center, Caldwell’s Union advance, and the senseless charge of the 7th Maine Infantry Regiment. A combination of GIS analysis, 3-D terrain modeling, viewshed analysis, and a review of the historical record, resulted in the identification of unit positions and movements derived from an examination of 2,033 military artifacts. This study provides a more detailed understanding of the events at Piper Farm and demonstrates potential applications to other battlefield landscapes.

Disturbance−diversity models: what do they really predict and how are they tested?
-
The intermediate disturbance hypothesis (IDH) and the dynamic equilibrium model (DEM) are influential theories in ecology. The IDH predicts large species numbers at intermediate levels of disturbance and the DEM predicts that the effect of disturbance depends on the level of productivity. However, various indices of diversity are considered more commonly than the predicted number of species in tests of the hypotheses. This issue reaches beyond the scientific community as the predictions of the IDH and the DEM are used in the management of national parks and reserves. In order to compare responses with disturbance among measures of biodiversity, we used two different approaches of mathematical modelling and conducted an extensive meta-analysis. Two-thirds of the surveyed studies present different results for different diversity measures. Accordingly, the meta-analysis showed a narrow range of negative quadratic regression components for richness, but not evenness. Also, the two models support the IDH and the DEM, respectively, when biodiversity is measured as species richness, but predict evenness to increase with increasing disturbance, for all levels of productivity. Consequently, studies that use compound indices of diversity should present logical arguments, a priori, to why a specific index of diversity should peak in response to disturbance.

Hawaiʻi Volcanoes National Park
-
Hawai‘i Volcanoes National Park protects some of the most unique geological, biological, and cherished cultural landscapes in the world. Extending from sea level to 13,681 feet, the park encompasses the summits of two of the world's most active volcanoes - Kīlauea and Mauna Loa - and is a designated International Biosphere Reserve and UNESCO World Heritage Site.
