Razorback Sucker (Xyrauchen Texanus) Recovery Plan, Harold M. Tyus

All U.S. Government Documents (Utah Regional Depository)

The Colorado River of the American West supports a mainstream fish community that is classified as the “Big River” fishes. Four of these fishes are listed as endangered under provisions of the Endangered Species Act of 1973, as amended. Three fishes (i.e., Colorado pike minnow Ptychocheilus Lucius, humpback chub Gila cypha, and bonytail G. elegans) have been listed for over 10 years, and they have recovery plans that were prepared prior to designation of critical habitats. Recently the Colorado squawfish was renamed by the American Fisheries Society and hereafter will be refered to in this document as the Colorado pike …

Invasive Plants: Changing The Landscape Of America, Federal Interagency Committee For The Management Of Noxious And Exotic Weeds, Randy G. Westbrooks

All U.S. Government Documents (Utah Regional Depository)

In the 1950s, the American public became aware that certain chemicals endanger human health and the environment. In response to this threat, new rules and regulations regarding chemical manufacture, use, and disposal were developed under state and federal law. Today, the public has a much better understanding of the chemical pollution problem and generally supports management efforts. The 1990s have brought us face to face with another serious environmental threat: The invasion of the American landscape by aggressive nonnative plants. While farmers have always fought a battle with weeds in crops, invasion of these and other formerly weed-free lands has …

Mud Creek Urban Nonpoint Source Demonstration, Paul Vendrell, K. Teague

Arkansas Water Resources Center Technical Reports

Northwest Arkansas is the seventh fastest developing area in the nation. The conversion of rolling pastureland into paved city streets, parking lots, and buildings within this rapidly urbanizing region is reducing infiltration and intensifying stormwater runoff. In the city of Fayetteville alone, the population increased from 42,099 to 58,163 between 1990 and 1999, moving the city across the population threshold which will require the Phase II Stormwater Permit process. Approximately half of Fayetteville is included in the Illinois River Watershed, which has been identified as the third highest priority watershed in need of restoration in the state of Arkansas. Mud …

A Lattice Model For Computing The Transmissivity Of The Cornea And Sclera, David B. Ameen, Marilyn F. Bishop, Tom Mcmullen

Physics Publications

Abstract

The method of photonic band structure is used to calculate the frequencies of light that propagate in lattice models of the cornea and sclera of the mammalian eye, providing an explanation for transparency in the cornea that first properly accounts for multiple scattering of light. Each eye tissue is modeled as an ordered array of collagen rods, and photonic band structure methods are used to solve Maxwell's equations exactly for these models, a procedure that automatically effectively includes all orders of multiple scattering. These calculations show that the dispersion relation for the cornea is linear in the visible range, …

Magnetostratigraphy Of Cueva Del Aleman, Isla De Mona, Puerto Rico And The Species Duration Of Audobon's Shearwater, Bruce C. Panuska, John M. Mylroie, Darrell Armentrout, Donald A. Mcfarlane

WM Keck Science Faculty Papers

Magnetostratigraphic analysis of deposits exposed in Cueva del Aleman shows two reversed and two normal chronozones. The lower normal polarity event is observed in a clastic dike and probably predates initial cave formation. Sediments deposited inside the cave proper show a R-N-R sequence and probably date to at least 1.8 Ma. A fossiliferous clastic dike contains normal polarity with an overlying reversed magnetozone. Audubon’s Shearwater (bird) bones occur in the dike, which is tentatively correlated with the lower N polarity zone predating cave formation. If this correlation is correct, the Audubon’s Shearwater (Puffinus lherminieri) range can be extended back to …

Decision Record For The Environmental Assessment For Coal Planning Decisions In The Carbon Basin Area Of The Great Divide Resource Area, United States Department Of The Interior, Bureau Of Land Management

Record of Decisions (WY)

The Federal Coal Leasing Amendments Act of 1976 requires that Federal coal lands to be considered for leasing must be identified in a comprehensive land use plan. At the time the Great Divide Resource Management Plan (GDRA RMP, 1990) was prepared, approximately 60% of the Federal coal lands in the Carbon Basin Coal Area were leased and exempt from the coal screening/planning process. Subsequently, development of this lease was never pursued and the lease expired. In addition, the coal screening/planning process was not conducted on the remainder of the Federal coal lands in the Carbon Basin area during the RMP …

Stable Isotope Analyses Of Tooth Annuli Reveal Temporal Dietary Records: An Example Using Stellar Sea Lions, Keith Hobson, John Sease

United States Department of Commerce: Staff Publications

Stable isotope analysis of teeth of marine mammals can provide valuable information on trophic level and source of feeding. However, the isotopic analysis of whole teeth presents only an average dietary estimate for individuals across the period of growth of that tooth. While such analyses can be valuable, particularly in the case of fossil material, in contrast, isotopic analysis of individual annuli of teeth can provide dietary information for each year of tooth growth, in some cases representing the whole of the animal's life. We measured stable-carbon isotope ratios (¹³C/¹²C) in the inorganic (hydroxyapatire) and stable-nitrogen …

The Simple Genetic Algorithm And The Walsh Transform: Part I: Theory, Michael D. Vose, Alden H. Wright

Computer Science Faculty Publications

This paper is the first part of a two-part series. It proves a number of direct relationships between the Fourier transform and the simple genetic algorithm. (For a binary representation, the Walsh transform is the Fourier transform.) The results are of a theoretical nature and are based on the analysis of mutation and crossover. The Fourier transform of the mixing matrix is shown to be sparse. An explicit formula is given for the spectrum of the differential of the mixing transformation. By using the Fourier representation and the fast Fourier transform, one generation of the infinite population simple genetic algorithm …

Foraging Modes Of Chinstrap Penguins: Contrasts Between Day And Night, John K. Jansen, Peter L. Boveng, John L. Bengtson

United States Department of Commerce: Staff Publications

Penguins rely on vision to travel and hunt at sea. Vision in marine predators, particularly those hunting phototactic prey under a broad range of light intensities, must be better understood to realize how these species respond to changes in their environment. We studied the effects of daily cycles in light intensity on visual predators by examining the duration and timing of chinstrap penguins' Pygoscelis Antarctica foraging trips and the size, composition, and timing of their meals. We used radio telemetry and stomach-contents sampling to study adult penguins that were provisioning chicks during the summers of 1993 and 1994 at Seal …

Sounds Recorded From Baird's Beaked Whale, Berardius Bairdii, Stephen Dawson, Jay Barlow, Don Ljungblad

United States Department of Commerce: Staff Publications

The vocal behavior of ziphiid whales is very poorly known. Free-swimming northern bottlenose whales, Hyperoodon ampullatus, have been recorded producing 3-16 kHz whistles and chirps (Winn et al. 1970; linear equipment frequency response 500 Hz-14 kHz) and 20-30 kHz ultrasonic clicks (Fauchner and Whitehead, unpublished data; equipment response to 35 kHz). A free-swimming mesoplodont beaked whale (probably Mesoplodon hertori) produced ultrasonic clicks (Ljungblad, unpublished data; equipment frequency response to 32 kHz). Sounds have been recorded from a stranded Blainville's beaked whale, Mesoplodon densirostris (Caldwell and Caldwell 1971; equipment frequency response 40 Hz-20 kHz) and a post-stranding, captive …

Seasonal Patterns In The Abundance And Distribution Of California Cetaceans, 1991-1992, Karin A. Forney, Jay Barlow

United States Department of Commerce: Staff Publications

This study presents a detailed seasonal comparison of the abundance and distribution of cetaceans within 100-150 nmi (185-278 km) of the California coast during 1991 and 1992. The results of a shipboard line-transect survey conducted in July-November 1991 (“summer”) were compared to those from aerial line-transect surveys conducted in March-April 1991 and February-April 1992 (“winter”). Using a confidence-interval-based bootstrap procedure, abundance estimates for six of the eleven species included in the comparison exhibited significant (a = 0.05) differences between the winter and summer surveys. Pacific white-sided dolphins (Lagenorhynchus obliquidens), Risso’s dolphins (Grampus griseus), common dolphins ( …
