Endocrine control of osmoregulation teleost fish
Stephen D. McCormick
2001, American Zoologist (41) 781-794
As the primary link between environmental change and physiological response, the neuroendocrine system is a critical part of osmoregulatory adaptations. Cortisol has been viewed as ‘the’ seawater-adapting hormone in fish and prolactin as ‘the’ fresh water adapting hormone. Recent evidence indicates that the growth hormone/insulin-like growth factor I axis is...

R. C. Cipriano, B.M. Novak, D.E. Flint, D.C. Cutting
2001, Journal of Aquatic Animal Health (13) 320-327
The U.S. Fish and Wildlife Service federal protocol for dual disinfection of fish eggs in 50 mg/L iodine solution for 30 min followed by a secondary disinfection in 100 mg/L iodine for 10 min was investigated during six spawning cycles of Atlantic salmon Salmo salar held at the Richard Cronin National Salmon...

Catherine S. Dees, Joseph D. Clark, Frank T. van Manen
2001, Journal of Wildlife Management (65) 141-147
The Florida panther (Puma concolor coryi) is one of the most endangered mammals in the world, with only 30-50 adults surviving in and around Florida Panther National Wildlife Refuge and the adjacent Big Cypress National Preserve. Managers at these areas conduct annual prescribed burns in pine (Pinus sp.) as a cost-effective method...

B. H. Letcher, T.D. Terrick
2001, North American Journal of Fisheries Management (21) 102-110
Stocked fry are the primary source of fish for the restoration effort for Connecticut River Atlantic salmon Salmo salar, yet it is unknown whether there is a developmental stage at stocking that yields optimal growth and survival or whether good growth and survival can be achieved across a wide range of...

2001, Journal of Geophysical Research E: Planets (106) 17635-17650
The Mars Descent Imager, or MARDI, experiment on the Mars Polar Lander (MPL) consists of a camera characterized by small physical size and mass (∼6×6×12 cm, including baffle; <500 gm), low power requirements (<2.5 W, including power supply losses), and high science performance (1000×1000 pixel, low noise). The intent of...
Developing a post-fire flood chronology and recurrence probability from alluvial stratigraphy in the Buffalo Creek watershed, Colorado, USA
J. G. Elliott, R. S. Parker
2001, Hydrological Processes (15) 3039-3051
Stratigraphic and geomorphic evidence indicate floods that occur soon after forest fires have been intermittent but common events in many mountainous areas during the past several thousand years. The magnitude and recurrence of these post-fire flood events reflects the joint probability between the recurrence of fires and the recurrence of...

Groundwater quality with respect to nitrate, major inorganic constituents, stable isotopes, and tritium was assessed in the agricultural Tangshan region in the Hai He River Basin of the People's Republic of China and compared with three regions in the U.S.: the Delmarva Peninsula of Delaware, Maryland, and Virginia; the San...
Microsatellite DNA variation Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) and cross-species amplification the Acipenseridae
T.L. King, B.A. Lubinski, A.P. Spidle
2001, Conservation Genetics (2) 103-119
Overharvest and habitat alteration have led to a collapse of most commercial Atlantic sturgeon(Acipenser oxyrinchus oxyrinchus)fisheries while pushing the species to rarity or extirpation in most of its historical range. A biologically sound conservation program for this species requires knowledge of its genetic diversity and of the evolutionary relationships among...
Influences of introduced plague on North American mammals: Implications from ecology of plague in Asia
E. Biggins, M.Y. Kosoy
2001, Journal of Mammalogy (82) 906-916
Intercontinental movements of invasive species continue to modify the world's ecosystems. The plague bacterium (Yersinia pestis) has colonized and altered animal communities worldwide but has received much more attention as a human pathogen. We reviewed studies on the ecology of Y. pestis in ancient foci of central Asia and in...

Hydrology of Yucca Mountain, Nevada
A. L. Flint, L. E. Flint, E. M. Kwicklis, G.S. Bodvarsson, J. M. Fabryka-Martin
2001, Reviews of Geophysics (39) 447-470
Yucca Mountain, located in southern Nevada in the Mojave Desert, is being considered as a geologic repository for high-level radioactive waste. Although the site is arid, previous studies indicate net infiltration rates of 5-10 mm yr-1 under current climate conditions. Unsaturated flow of water through the mountain generally is vertical...
Microsatellite analyses of the trout of northwest Mexico
J.L. Nielsen, G. Kevin Sage
2001, Genetica (111) 269-278
The trout of northwest Mexico represent an undescribed group of fish considered part of the Oncorhynchus mykiss (Pacific trout) complex of species and subspecies. Recent genetic studies have shown these fish to have important genetic diversity and a unique evolutionary history when compared to coastal rainbow trout. Increased levels of...

D. Gesch, J. Williams, W. Miller
2001, Conference Paper, International Geoscience and Remote Sensing Symposium (IGARSS)
Elevation models produced from Shuttle Radar Topography Mission (SRTM) data will be the most comprehensive, consistently processed, highest resolution topographic dataset ever produced for the Earth's land surface. Many applications that currently use elevation data will benefit from the increased availability of data with higher accuracy, quality, and resolution, especially...

Physiological variation among native and exotic winter annuals associated with microphytic soil crusts in the Mojave Desert
Lesley DeFalco, James K. Detling, C. Richard Tracy, Steven D. Warren
2001, Plant and Soil (234) 1-14
Microbiotic crusts are important components of many aridland soils. Research on crusts typically focuses on the increase in soil fertility due to N-fixing micro-organisms, the stabilization of soils against water and wind erosion and the impact of disturbance on N-cycling. The effect of microbiotic crusts on the associated plant community...
