Effects of long-term changes in the benthic community on yellow perch in Saginaw Bay, Lake Huron
Jeffrey S. Schaeffer, James S. Diana, Robert C. Haas
2000, Journal of Great Lakes Research (26) 340-351
Abundance, mortality, age and growth, food habits, and energetics of a yellow perch Perca flavescens population were investigated in eutrophic Saginaw Bay, Lake Huron during May to October, 1986 to 1988, and compared population characteristics with historical data from times when eutrophic conditions were less severe. During 1986 to 1988,...

Microscopic functional anatomy: Integumentary system: Chapter 17
Diane G. Elliott
Gary K. Ostrander, editor(s)
2000, Book chapter, The laboratory fish
Many of the features of the fish integument can only be observed microscopically. Because there are over 20,000 living fishes, mostly higher bony fishes (teleosts), a great diversity exists in the microscopic anatomy of the integument. This chapter presents several examples from varied taxonomic groups to illustrate the variation in...

A diurnal animation of thermal images from a day-night pair
K. Watson
2000, Remote Sensing of Environment (72) 237-243
Interpretation of thermal images is often complicated because the physical property information is contained in both the spatial and temporal variations of the data and thermal models are necessary to extract and display this information. A linearized radiative transfer solution to the surface flux has been used to derive a...
Holocene environmental and climatic change in the Northern Great Plains as recorded in the geochemistry of sediments in Pickerel Lake, South Dakota
W.E. Dean, A. Schwalb
2000, Quaternary International (67) 5-20
The sediments in Pickerel Lake, northeastern South Dakota, provide a continuous record of climatic and environmental change for the last 12000 yr. Sediments deposited between 12 and 6 ka (radiocarbon) show extreme variations in composition, oxygen and carbon isotopic composition of bulk carbonate, carbon isotopic composition of organic matter, and...
Detection of gas hydrate with downhole logs and assessment of gas hydrate concentrations (saturations) and gas volumes on the Blake Ridge with electrical resistivity log data
T. S. Collett, J. Ladd
2000, Conference Paper, Proceedings of the Ocean Drilling Program: Scientific Results
Let 164 of the Ocean Drilling Program was designed to investigate the occurrence of gas hydrate in the sedimentary section beneath the Blake Ridge on the southeastern continental margin of North America. Site 994, and 997 were drilled on the Blake Ridge to refine our understanding of the in situ...
The disparity between extreme rainfall events and rare floods - with emphasis on the semi-arid American West
W. R. Osterkamp, Jonathan M. Friedman
2000, Hydrological Processes (14) 2817-2829
Research beginning 40 years ago suggested that semi-arid lands of the USA have higher unit discharges for a given recurrence interval than occur in other areas. Convincing documentation and arguments for this suspicion, however, were not presented. Thus, records of measured rainfall intensities for specified durations and recurrence intervals, and...
Potential effects of climate change on surface-water quality in North America
Peter S. Murdoch, Jill Baron, T. L. Miller
2000, Journal of the American Water Resources Association (36) 347-366
Data from long-term ecosystem monitoring and research stations in North America and results of simulations made with interpretive models indicate that changes in climate (precipitation and temperature) can have a significant effect on the quality of surface waters. Changes in water quality during storms, snowmelt, and periods of elevated air...
Environmental contaminants in blood, hair, and tissues of ocelots from the Lower Rio Grande Valley, Texas, 1986-1997

2000, Environmental Monitoring and Assessment (64) 477-492
The ocelot (Felis pardalis) is an endangered neotropical cat distributed within a small range in the Lower Rio Grande Valley (LRGV), in Texas, U.S.A. Studies of the impacts of environmental contaminants in wild cats are few. Approximately one fourth of the estimated population (about 100) of ocelots in the LRGV...
Stratigraphy, geochemistry and tectonic significance of the Oligocene magmatic rocks of western Oaxaca, southern Mexico
B. Martiny, R. G. Martinez-Serrano, D. J. Moran-Zenteno, C. MacIas-Romo, R. A. Ayuso
2000, Conference Paper, Tectonophysics
In Western Oaxaca, Tertiary magmatic activity is represented by extensive plutons along the continental margin and volcanic sequences in the inland region. K-Ar age determinations reported previously and in the present work indicate that these rocks correspond to a relatively broad arc in this region that was active mainly during...
Instrumental lahar monitoring at Merapi Volcano, Central Java, Indonesia

2000, Journal of Volcanology and Geothermal Research (100) 457-478
More than 50 volcanic debris flows or lahars were generated around Mt Merapi during the first rainy season following the nuees ardentes of 22 November 1994. The rainfalls that triggered the lahars were analyzed, using such instruments as weather radar and telemetered rain gauges. Lahar dynamics were also monitored, using...

Using multi-scale sampling and spatial cross-correlation to investigate patterns of plant species richness
M. A. Kalkhan, T.J. Stohlgren
2000, Environmental Monitoring and Assessment (64) 591-605
Land managers need better techniques to assess exoticplant invasions. We used the cross-correlationstatistic, IYZ, to test for the presence ofspatial cross-correlation between pair-wisecombinations of soil characteristics, topographicvariables, plant species richness, and cover ofvascular plants in a 754 ha study site in RockyMountain National Park, Colorado, U.S.A. Using 25...
