F. Yuan, W.-Z. Song, N. Peterson, Y. Peng, L. Wang, B. Shirazi, R. LaHusen
2008, Conference Paper, 6th Annual IEEE International Conference on Pervasive Computing and Communications, PerCom 2008
In this paper, we propose a lightweight and transparent management framework for TinyOS sensor networks, called L-SNMS, which minimizes the overhead of management functions, including memory usage overhead, network traffic overhead, and integration overhead. We accomplish this by making L-SNMS virtually transparent to other applications hence requiring minimal integration. The...

Seasonal passerine migratory movements over the arid Southwest
Rodney K. Felix, Robert H. Diehl, Janet M. Ruth
2008, Studies in Avian Biology (37) 126-137
Biannually, millions of Neotropical and Nearctic migratory birds traverse the arid southwestern US-Mexico borderlands, yet our knowledge of avian migration patterns and behaviors in this region is extremely limited. To describe the spatial and temporal patterns of migration, we examined echoes from weather surveillance radar sites across the American Southwest...
Modeling the effects of fire severity and spatial complexity on Small Mammals in Yosemite National Park, California
Susan L. Roberts, Jan W. Van Wagtendonk, A. Keith Miles, Douglas A. Kelt, James A. Lutz
2008, Fire Ecology (4) 83-104
We evaluated the impact of fire severity and related spatial and vegetative parameters on small mammal populations in 2 yr- to 15 yr-old burns in Yosemite National Park, California, USA. We also developed habitat models that would predict small mammal responses to fires of differing severity. We hypothesized that fire...

For most large U.S. parks and wilderness areas, enabling legislation and management policy call for preservation of these protected areas unimpaired in perpetuity. Central to the notions of protection, preservation, and unimpairment has been the concept of maintaining “naturalness,” a condition imagined by many to persist over time in the...
Ecology in the information age: Patterns of use and attrition rates of internet-based citations in ESA journals, 1997–2005
Jeffrey J. Duda, Richard J. Camp
2008, Frontiers in Ecology and the Environment (6) 145-151
As the amount of information available on the internet has increased, so too has the number of citations to network-accessible information in scholarly research. We searched all papers in four Ecological Society of America journals from 1997 to 2005 for articles containing a citation to material on the internet. We...
At-sea distribution of satellite-tracked grey-faced petrels, Pterodroma macroptera gouldi, captured on the Ruamaahua (Aldermen) Islands, New Zealand

The use of groundwater age as a calibration target
Leonard F. Konikow, G.Z. Hornberger, L.D. Putnam, A.M. Shapiro, B.A. Zinn
2008, Conference Paper, IAHS-AISH Publication
Groundwater age (or residence time), as estimated on the basis of concentrations of one or more environmental tracers, can provide a useful and independent calibration target for groundwater models. However, concentrations of environmental tracers are affected by the complexities and mixing inherent in groundwater flow through heterogeneous media, especially in...
Multistage late Cenozoic evolution of the Amargosa River drainage, southwestern Nevada and eastern California Society of America. All rights reserved
C.M. Menges
2008, Conference Paper, Special Paper of the Geological Society of America
Stratigraphic and geomorphic analyses reveal that the regional drainage basin of the modern Amargosa River formed via multistage linkage of formerly isolated basins in a diachronous series of integration events between late Miocene and latest Pleistocene-Holocene time. The 275-km-long Amargosa River system drains generally southward across a large (15,540 km<sup>...
