Fisheries Research Report No. 119 - Final Report, Frdc Project 95/037: The Biology And Stock Assessment Of The Tropical Sardine, Sardinella Lemuru, Off The Mid-West Coast Of Western Australia, Daniel J. Gaughan, Ronald W. Mitchell May 2000

Fisheries Research Report No. 119 - Final Report, Frdc Project 95/037: The Biology And Stock Assessment Of The Tropical Sardine, Sardinella Lemuru, Off The Mid-West Coast Of Western Australia, Daniel J. Gaughan, Ronald W. Mitchell

Fisheries Research Reports

Exploratory fishing for the tropical sardine, Sardinella lemuru, offshore of Geraldton on the midwest coast of Western Australia in the early 1990s, led to the establishment of a developmental purse seine fishery in this region. This fishery showed potential for substantial expansion, but as there was no information on S. lemuru in WA there was a need to undertake research during the developmental period. The biology and fishery for S. lemuru in WA were therefore investigated over a three year period between July 1995 and June 1998 with the aim of providing stock assessment advice.

The biology of S. lemuru …


Fisheries Research Report No. 121 - Synopsis Of The Biology And Exploitation Of The Blue Swimmer Crab, Portunus Pelagicus Linnaeus, In Western Australia, Mervi I. Kangas May 2000

Fisheries Research Report No. 121 - Synopsis Of The Biology And Exploitation Of The Blue Swimmer Crab, Portunus Pelagicus Linnaeus, In Western Australia, Mervi I. Kangas

Fisheries Research Reports

This report summarises the existing studies which have provided information on the biology, population characteristics and exploitation of the blue swimmer crab, Portunus pelagicus, in Western Australia. Gaps in the existing knowledge are also highlighted to assist in targeting new research initiatives. Portunus pelagicus matures at about one year and in temperate regions females mate only once a year. This is because mature crabs moult only once a year. It appears from studies to date that Western Australian crabs are one genetic population. This is being further investigated. Migration of the blue swimmer crab occurs between estuaries and the ocean …

Fisheries Research Report No. 120 - A 12-Month Survey Of Recreational Fishing In The Leschenault Estuary Of Western Australia During 1998, B E. Malseed, Neil R. Sumner, P C. Williamson

Fisheries Research Reports

A survey of recreational boat-based and shore-based fishing in the Leschenault Estuary was conducted between January 1998 and December 1998. The survey estimated the total annual boat-based recreational fishing effort as 33,392 fisher days, with 86% of this effort targeting blue swimmer crabs. The total annual shore-based recreational fishing effort was estimated to be 5,610 fisher days, with 88% of this effort targeting blue swimmer crabs.

The recreational blue swimmer crab catch from the Leschenault Estuary is substantial and exceeds the reported commercial catch. The estimated total recreational catch of blue swimmer crabs was 219,000 crabs or 45.7 tonnes. This …

Phytoremediation Of A Pyrene-Contaminated Cecil Soil With Annual Ryegrass (Lolium Multiflorum Lam.), Teddy Luc Lalande May 2000

Phytoremediation Of A Pyrene-Contaminated Cecil Soil With Annual Ryegrass (Lolium Multiflorum Lam.), Teddy Luc Lalande

All Theses

Phytoremediation of polycyclic aromatic hydrocarbons (PAHs) is inconsistent and the microbial mechanisms involved are unclear. We evaluated the effect of annual ryegrass (Lolium multiflorum Lam.) and P availability on the degradation of pyrene (600mg kg-1 dry soil) in the top 7.5-cm of a Cecil sandy loam (fine, kaolinitic, thermic Typic Kanhapludults) over a 10-month experiment under field conditions in Clemson, SC. Changes associated with the soil microbial community were also evaluated. Plastic canopies were installed to prevent leaching and raindrop dispersion of pyrene. Treatment factors were pyrene, vegetation, and available P levels in a complete factorial experiment with four replications. …


An Examination Of Gasoline Pollutants From Two-Cycle Marine Engines Within Lake Mead National Recreation Area, Brian Carter May 2000

An Examination Of Gasoline Pollutants From Two-Cycle Marine Engines Within Lake Mead National Recreation Area, Brian Carter

UNLV Theses, Dissertations, Professional Papers, and Capstones

Jet skis are a very popular "toy" to have in the United States. They account for almost a third of all boat sales, and their numbers are growing rapidly. Unfortunately jet skis use two-cycle engines that pollute at unacceptable levels. Jet ski motors can emit up to 25% of its fuel right back into the water. This alarmed me and I wanted to take a deeper look into how bad jet skis pollute Las Vegas' primary water source. Lake Mead. I looked into how a two-cycle engine differs from a regular engine and I looked at the actual pollutants a …


Wetland Mitigation Banking As A Tool For Conservation, Reid Beauregard Sisson May 2000

Wetland Mitigation Banking As A Tool For Conservation, Reid Beauregard Sisson

Masters Theses and Doctoral Dissertations

This comment proposes that wetland mitigation banking under Section 404 of the Clean Water Act be employed by land trusts and conservation groups to generate revenue for funding land acquisitions and on-going stewardship for both wetland and wetland-related upland habitats threatened or impacted by development. Conservation groups and land trusts can use mitigation banking to generate revenue to fund their conservation goals. General background on the Clean Water Act - Section 404 and regulations affecting wetlands, compensatory mitigation and mitigation banking is provided. Included are general problems with monitoring and enforcement of mitigation, pros and cons of preservation as compensatory …


Changes In Coyote Activity Patterns Due To Reduced Exposure To Human Persecution, Ann M. Kitchen, Eric M. Gese, Edward R. Schauster Apr 2000

Changes In Coyote Activity Patterns Due To Reduced Exposure To Human Persecution, Ann M. Kitchen, Eric M. Gese, Edward R. Schauster

United States Department of Agriculture Wildlife Services: Staff Publications

Activity patterns in animals are influenced by a number of factors, including the animal's physiological adaptations, prey availability and distribution, and disturbances caused by predators and humans. We compared coyote (Canis latrans) activity patterns estimated using radio-tracking locations between 1983 and 1988 with those documented between 1996 and 1997 on the Pinon Canyon Maneuver Site, in southeastern Colorado. We tested the hypothesis that changes in the type of disturbance experienced by coyotes would result in changes in their activity patterns. Disturbance experienced by the coyote population studied during 1983-1988, included >50 years of intense exploitation (shooting and trapping by ranchers) …


Wildlife Strikes: A Growing And Costly Problem For Civil Aviation In The Usa, Sandra Wright, Richard Dolbeer Apr 2000

Wildlife Strikes: A Growing And Costly Problem For Civil Aviation In The Usa, Sandra Wright, Richard Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife strikes, defined as aircraft collisions with birds or other animals, are a serious safety and economic concern in the USA and elsewhere. Liability issues related to wildlife strikes are also growing for airports and aircraft operators. In this paper, we will give examples of some significant strikes, show trends in wildlife strikes, explain why the strike problem is an increasing concern and discuss what actions can be taken to reduce and prevent strikes.


Seasonal Variability In Brown Tree Snake (Boiga Irregularis) Response To Lures, John A. Shivik, William G. Wright, Larry Clark Apr 2000

Seasonal Variability In Brown Tree Snake (Boiga Irregularis) Response To Lures, John A. Shivik, William G. Wright, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

In continuing investigations of brown tree snake, Boiga irregularis, attraction to carrion odor, we hypothesized that the attractiveness of live or dead and visually apparent or concealed lures varies seasonally. We determined that lure condition (live or dead mouse lures) and sensory cues (visually apparent or concealed lure) interact among wet and dry seasons. Concealed carrion lures were more effective during the dry season than the wet season, but the effectiveness of live mouse lures showed less seasonal variability. We identified weather variables that covary with observed seasonal trends in capture rates and investigated the influence of recent feeding …


Immunocontraception Of White-Tailed Deer With Gnrh Vaccine, Lowell A. Miller, Brad E. Johns, Gary J. Killian Apr 2000

Immunocontraception Of White-Tailed Deer With Gnrh Vaccine, Lowell A. Miller, Brad E. Johns, Gary J. Killian

United States Department of Agriculture Wildlife Services: Staff Publications

One of the most successful immunocontraceptive vaccines used for wildlife is porcine zona pellucida (PZP). Several authors have published on the use of PZP immunocontraceptive vaccines to immunosterilize white-tailed deer. This is the first long term study of the use of GnRH contraception of deer. This GnRH immunocontraceptive study was part of a multi-year White- Tailed deer infertility study on the deer herd at Pennsylvania State University, (PSU) University Park, Pennsylvania in cooperation with National Wildlife Research Center, (NWRC) Fort Collins, CO.


Reporting Bias In Bird Strikes At John F Kennedy International Airport, New York, 1979-1998, Scott C. Barras, Richard A. Dolbeer Apr 2000

Reporting Bias In Bird Strikes At John F Kennedy International Airport, New York, 1979-1998, Scott C. Barras, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Bird-aircraft strike databases have been used to identify, monitor, and manage bird strike problems in the USA nationally and at individual airports. Up to 75% of all bird strikes that occur in the USA may not be reported by pilots or airport control tower personnel. Recent studies have suggested that individual airports may improve their strike reporting rates by having personnel regularly search runways for the remains of birds struck by aircraft. We analyzed a 20-year dataset of runway searches from John F. Kennedy International Airport (JFKIA) in New York to determine the degree of bias in reports of strikes …


Roles Of Odor, Taste, And Toxicity In The Food Preferences Of Lambs: Implications For Mimicry In Plants, Frederick D. Provenza, Bruce A. Kimball, Juan J. Villalba Apr 2000

Roles Of Odor, Taste, And Toxicity In The Food Preferences Of Lambs: Implications For Mimicry In Plants, Frederick D. Provenza, Bruce A. Kimball, Juan J. Villalba

United States Department of Agriculture Wildlife Services: Staff Publications

In the traditional sense, food ingestion consists of prehending, masticating, swallowing, and digesting plant matter. It is also possible to ingest plants without eating them. Volatile compounds are inhaled directly into the lungs and transported from the lungs into the bloodstream. Volatiles in high concentrations could presumably produce toxicosis, without an herbivore ever ingesting a plant in the customary sense. Volatile compounds may be aposematic, serving to warn potential predators of toxins in plants. We conducted three experiments to explore the roles of odor, taste, and toxicity in the food preferences of lambs. The first experiment determined if brief exposure …


Captive Great Blue Heron Predation On Farmed Channel Catfish Fingerlings, James F. Glahn, Brian Dorr, Mark E. Tobin Apr 2000

Captive Great Blue Heron Predation On Farmed Channel Catfish Fingerlings, James F. Glahn, Brian Dorr, Mark E. Tobin

United States Department of Agriculture Wildlife Services: Staff Publications

In a series of experiments, we examined feeding behavior of captive great blue herons Ardea herodius and estimated their ability to affect commercial production of fingerling channel catfish Ictalurus punctatus. Specifically, we determined the following: (1) the biomass of channel catfish fingerlings necessary to maintain the body mass of wild-caught captive great blue herons, (2) capture rates of captive great blue herons foraging on channel catfish fingerlings, (3) evaluation of the losses of catfish fingerlings to heron predation, and (4) the effects of selected catfish pond conditions on heron capture rates and body mass changes. Consistent with previous studies, …

Muir Center Newsletters (1981-2015)

NEWSLETTER M Transcendentalist by L. Mikel Vause, Weber State University he term "transcendentalist" evokes an interesting image. Generally when one thinks of a transcendentalist, the image of a little brown-skinned mystic, sitting in lotus position chanting "ommm" comes to ihind. Although American transcendentalism certainly does have Far Eastern roots, one ascribing to that title is Br more likely to be found tramping around the back country rather than curled up on a mat contemplating the ilssence of existence. The founder of American transcendentalism is Ralph Waldo Emerson, "The Sage of Concord." It was Emerson who, with the publication of Nature …

The True Truth About Kgi And The Field Station, Paul Faulstich Apr 2000

The True Truth About Kgi And The Field Station, Paul Faulstich

Pitzer Faculty Publications and Research

There are multiple truths. One is the true truth. This truth remains the same no matter what anyone thinks or says about it. For example, it is true truth that we need oxygen. and that trees provide it. No matter what we think or say about it, this is the way it is. And, the Bernard Biological Field Station is habitat to threatened and endangered plants and animals. This, too, we know to be true.

Examination Of The Bureau Of Land Management's Implementation Of The Wild, Free-Roaming Horse And Burro Act At Red Rock National Conservation Area, Christine E. Brehm Apr 2000

Examination Of The Bureau Of Land Management's Implementation Of The Wild, Free-Roaming Horse And Burro Act At Red Rock National Conservation Area, Christine E. Brehm

UNLV Theses, Dissertations, Professional Papers, and Capstones

For unknown reasons horses went extinct on the North American continent approximately ten thousand years ago and were subsequently reintroduced by Spanish settlers in the 1400's. As European settlers moved westward, horses were perceived as competition for grasslands and their numbers were curtailed. Wild horses were granted Federal protection in 1959 with the passage of the 'Wild Horse Annie' law and further protected with the passage of the Wild, Free-Roaming Horse and Burro Act of 1971. Through the Department of the Interior, the Bureau of Land Management was charged with management of wild horses on public lands. Physical searches of …


Green Sea Turtle (Chelonia Mydas) Hatchlings Success: The Effects Of Artificial Lights And Other Human Impacts, Hui-Yu Tracy Liang Apr 2000

Green Sea Turtle (Chelonia Mydas) Hatchlings Success: The Effects Of Artificial Lights And Other Human Impacts, Hui-Yu Tracy Liang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sea turtles appeared more than 200 million years ago in the late Triassic period. They grow very slowly, taking an average of 25 years to reach sexual maturity, with a life span averaging 40-50 years. From May to October green sea turtles (Chelonia mydas) emerge during the night and follow light cues toward the sea. Recently, beachfront development has increased hatchling mortality rate. When hatchlings emerge from nest, high densities of artificial lights lead them toward the land where they either desiccate and die, or are preyed upon. Short-wavelength high intensity light and the distance of artificial light are the …


Deposition And Uptake Availability Of Lead Shot For Waterfowl At Honeybee Pond Within The Overton Wildlife Management Area, Nevada, Usa, Jason Eckberg Apr 2000

Deposition And Uptake Availability Of Lead Shot For Waterfowl At Honeybee Pond Within The Overton Wildlife Management Area, Nevada, Usa, Jason Eckberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lead shot has been banned for hunting waterfowl since 1974, but lead poisoning continues to be a major problem in many waterfowl habitats. In December of 1999, soil samples were collected from the Honeybee pond at the Overton Wildlife Management area to determine the lead pellet concentration and the availability of lead shot to waterfowl. There were no shot pellets recovered from the thirty-one samples taken from the pond. Based on this information waterfowl do not appear to be exposed to lead in the pond areas at OWMA.


Two Different Soil Sampling Techniques For Assessing Soil Lead Concentrations At The Overton Wildlife Management Area, Nevada, Kristen E. Falc Apr 2000

Two Different Soil Sampling Techniques For Assessing Soil Lead Concentrations At The Overton Wildlife Management Area, Nevada, Kristen E. Falc

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the summer of 1999, soil samples were taken from the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Although lead shot has been banned for the hunting of waterfowl since 1986, it is still legal for upland game hunting. The field sampled serves primarily as a dove hunting area and is cultivated. A large sample size was taken to indicate the short-term effects of the deposition of lead shot in the area and a small sample size, the long-term. Lead shot was recovered from 64% of the small samples and the estimated concentration …


Repellents To Reduce Cable Gnawing By Wild Norway Rats, Stephen A. Shumake, Ray T. Sterner, Stanley E. Gaddis Apr 2000

Repellents To Reduce Cable Gnawing By Wild Norway Rats, Stephen A. Shumake, Ray T. Sterner, Stanley E. Gaddis

United States Department of Agriculture Wildlife Services: Staff Publications

Rodents gnaw communications and power cables, resulting in service interruptions, fires, and other safety concerns. Commensal rodents such as the Norway rat (Rattus norvegicus) have been implicated in many of these situations. Two chemical repellents (capsicum oleoresin+apsaicin and denatonium benzoate) at 2.0% mass/mass concentrations in a polybutene carrier (Indopol-controlw) ere evaluated for repellent efficacy compared to a plastic mesh physical barrier material (Vexa*) and the polybutene carrier (placebo) alone using groups of individually caged wild Norway rats. The materials were applied to short lengths of communications cable (RG-8U) with the repellents enclosed in electrical shrink tubing around the …


Long-Term Spatial Stability Of Coyote (Canis Latrans) Home Ranges In Southeastern Colorado, Ann M. Kitchen, Eric M. Gese, Edward R. Schauster Apr 2000

Long-Term Spatial Stability Of Coyote (Canis Latrans) Home Ranges In Southeastern Colorado, Ann M. Kitchen, Eric M. Gese, Edward R. Schauster

United States Department of Agriculture Wildlife Services: Staff Publications

Long-term stability of territorial boundaries has not been well documented in canids. To evaluate the prevalence of long-term spatial stability of coyote (Canis latrans) home ranges, we compared the overlap of territorial boundaries and the spatial distribution of telemetry locations of packs in southeastern Colorado. From August 1983 to July 1988 (period l), 16 coyotes from six packs were radio-tracked. From April 1996 to August 1997 (period 2), 12 coyotes from six packs were captured and tracked in the same area. Mean percentage of overlap of pack ranges was 89.8 ± 8.3% (+SD) for period 1 ranges over …


Comparative Analysis Of Three Remediation Technologies For The Clean Up Of Petroleum Contaminated Groundwater, Thomas Bouck Apr 2000

Comparative Analysis Of Three Remediation Technologies For The Clean Up Of Petroleum Contaminated Groundwater, Thomas Bouck

UNLV Theses, Dissertations, Professional Papers, and Capstones

This paper will compare three remediation technologies to determine which is the most efficient and effective remediation treatment for a petroleum contaminated groundwater site. The three remediation technologies are in situ bioremediation, in situ air sparging, and air stripping with carbon filtration. This comparison will be done through a literature review. It will take the information derived from the review and then apply it to the information about a petroleum contaminated groundwater location. The comparative analysis will consist of these parameters permit requirements, clean up time, operating and maintenance, and geological factors.

These factors permit requirements, cleanup time, and operating …


Importance Of Migrating Salmon Smolt In Ring-Billed (Larus Delawarensis) And California Gull (L. Californicus) Diets Near Priest Rapids Dam, Washington, Darryl L. York, John L. Cummings, John E. Steuber, Patricia A. Pochop, Christi A. Yoder Apr 2000

Importance Of Migrating Salmon Smolt In Ring-Billed (Larus Delawarensis) And California Gull (L. Californicus) Diets Near Priest Rapids Dam, Washington, Darryl L. York, John L. Cummings, John E. Steuber, Patricia A. Pochop, Christi A. Yoder

United States Department of Agriculture Wildlife Services: Staff Publications

Ring-billed (Larus delawarensis) and California Gulls (L. californicus) have been implicated in depredations on migrating salmon smolt in the Columbia River. As part of a gull management program conducted in 1995 and 1996, we collected L. delawarensis (n = 120) and L. californicus (n = 45) near Priest Rapids Dam, Washington, and analyzed stomach contents to determine food habits and thus the importance of fish in gull diets. Percent volume measurements and index of relative importance rankings suggested a greater reliance on fish by L. californicus than by L. delawarensis. Peak percent consumption of fish by …

Movements And Distribution Of Radio-Collared Canada Geese In Anchorage, Alaska, Darryl York, John Cummings, Kate Wedemeyer

United States Department of Agriculture Wildlife Services: Staff Publications

We monitored radio-equipped (n = 50) and neck-collared (n = 205) lesser Canada geese (Branta canadensis parvipes) during August through October 1996 in Anchorage, Alaska, to ascertain local patterns of movement and post-molt dispersal; to identify geese from molting sites that frequent Elmendorf Air Force Base (EAFB); and to evaluate the effectiveness of hazing at EAFB. Telemetry data and visual observations of collared geese indicated 59% of geese observed at EAFB were from molting sites ≤10 km from EAFB. We observed 93 marked geese from 11 molting sites 1 or more times in the EAFB airdrome, and 63% …
