Jeffrey J. Danielson, John Brock, Daniel M. Howard, Dean B. Gesch, Jamie M. Bonisteel-Cormier, Laurinda J. Travers
2013, Data Series 769
Topobathymetric Digital Elevation Models (DEMs) are a merged rendering of both topography (land elevation) and bathymetry (water depth) that provides a seamless elevation product useful for inundation mapping, as well as for other earth science applications, such as the development of sediment-transport, sea-level rise, and storm-surge models. This 1/9-arc-second (approximately...
Dissolved oxygen fluctuations in karst spring flow and implications for endemic species: Barton Springs, Edwards aquifer, Texas, USA
Barbara Mahler, Renan Bourgeais
2013, Journal of Hydrology (505) 291-298
Karst aquifers and springs provide the dissolved oxygen critical for survival of endemic stygophiles worldwide, but little is known about fluctuations of dissolved oxygen concentrations (DO) and factors that control those concentrations. We investigated temporal variation in DO at Barton Springs, Austin, Texas, USA. During 2006–2012, DO fluctuated by as...

Gary M. Fellers, W Sparling, Laura McConnell, Patrick M. Kleeman, Leticia Drakeford
2013, Book chapter, Occurrence, fate and impact of atmospheric pollutants on environmental and human health
Previous studies have indicated that toxicity from pesticide exposure may be contributing to amphibian declines in California and that atmospheric deposition could be a primary pathway for pesticides to enter amphibian habitats. We report on a survey of California wetlands sampled along transects associated with Lassen Volcanic National Park, Lake...

Odor-conditioned rheotaxis of the sea lamprey: Modeling, analysis and validation
Jongeun Choi, Soo Jean, Nicholas S. Johnson, Cory O. Brant, Weiming Li
2013, Bioinspiration and Biomimetics (8)
Mechanisms for orienting toward and locating an odor source are sought in both biology and engineering. Chemical ecology studies have demonstrated that adult female sea lamprey show rheotaxis in response to a male pheromone with dichotomous outcomes: sexually mature females locate the source of the pheromone whereas immature females swim...

Plant invasions in protected areas of tropical pacific islands, with special reference to Hawaii
R. Flint Hughes, Jean-Yves Meyer, Lloyd L. Loope
2013, Book chapter, Plant Invasions in Protected Areas
Isolated tropical islands are notoriously vulnerable to plant invasions. Serious management for protection of native biodiversity in Hawaii began in the 1970s, arguably at Hawaii Volcanoes National Park. Concerted alien plant management began there in the 1980s and has in a sense become a model for protected areas throughout Hawaii...

Peter G. Chirico, Katherine C. Malpeli
2013, Scientific Investigations Report 2013-5185
Ethnic and political conflict developed into open civil war in Côte d’Ivoire in 2002, leading to a de facto partitioning of the country into the government-controlled south and the rebel-controlled north. Côte d’Ivoire’s two main diamond mining areas, Séguéla and Tortiya, are located in the north, under what was, until...

Mark D. Schwartz, editor(s)
2013, Book chapter, Phenology: An integrative environmental science
Plant phenological observations and networks in North America have been largely local and regional in extent until recent decades. In the USA, cloned plant monitoring networks were the exception to this pattern, with data collection spanning the late 1950s until approximately the early 1990s. Animal observation networks, especially for birds...
