Cougar Predation And Ecological Energetics In Southern Utah, Bruce Bennet Ackerman
Cougar Predation And Ecological Energetics In Southern Utah, Bruce Bennet Ackerman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Diet of cougars (Felis concolor) was studied from December 1978 to August 1981, on a 4500 km2 study area near Escalante, Utah. Prey eaten was determined from analysis of 112 animals consumed as prey, and from 239 cougar scats. Mule deer (Odocoileus hemionus) were the major prey item, comprising 81% of biomass consumed. Lagomorphs, large rodents, and smaller predators were also important components. Cattle comprised <1% of the diet, although commonly grazed on the cougar's summer range. Adult male and juvenile (<1yr) mule deer were killed more often than expected, in fall (P<0.10) and in winter (P<0.005). Cougars were a major cause of mortality of adult deer (41% of all adult female deaths, 35% of male), but only 6% of mortality of juveniles. Selection of prey seemed to be a function of prey vulnerability, rather than one of active choice by the predator.
Motion-sensitive radio-transmitters were placed on 15 cougars, from 3 months to 7-9 years of age. Three parameters of the radio signal were used to determine activity levels during 6843 …

Comparison Of Fishery Policies And Management Techniques Of The United States And Iceland, Ted I. Lillestolen
Marine Affairs Theses and Major Papers
In 1976, the United States enacted the Fishery Conservation and Management Act (FCMA), presently referred to as the Magnuson Fishery conservation and Management Act (MFCMA). The legislation is a complex and detailed document establishing for the first time a national fishery policy. The Act also created an organizational structure designed to implement this new policy. Since the Act's implementation, there has been a great deal of controversy, especially generated by the commercial fishermen. This paper focuses on Iceland, primarily because of its great economic dependency on its fisheries resources, unlike the United States.
A Laboratory Study Of Nongenetic Embryonic Adaptation To Salinity And Its Subsequent Effects Upon Larval Development Of The Grass Shrimp Palaemonetes Pugio Holthius, Paul Jay Anninos
OES Theses and Dissertations
Fertilized embryos of the grass shrimp Palamonetes pugio Holthuis (Decapoda; Caridea) were exposed to two levels of salinity [5 ppt (exposed) and 20 ppt (control)] during incubation to determine the extent to which embryonic adaptation influences subsequent larval development. Larval response to embryonic exposure was measured at three salinities (5 ppt, 10 ppt, and 20 ppt) as the fraction of larvae surviving to metamorphosis and the duration (in days) of larval development. The survival rate of larvae hatched from control, or non-adapted, embryos was significantly influenced by rearing salinity. The differences in survival of pre-adapted larvae (exposed group), however, were …

The Aquatic Toxicity Of Organic Compounds To Embryo-Larval Stages Of Fish And Amphibians, Jeffrey A. Black, Wesley J. Birge, Willaim E. Mcdonnell, Albert G. Westerman, Barbara A. Ramey, Donald M. Bruser
KWRRI Research Reports
Aquatic toxicity tests were conducted on 11 organic compounds considered hazardous to water resources. The toxicity of each compound was evaluated using embryo-larval stages of two to eight fish and amphibian species. Exposure was initiated at fertilization and maintained through 4 days posthatching. The animal test species exhibited varying degrees of sensitivity to the selected toxicants. Combined frequencies for mortality and teratogenesis at 4 days posthatching gave LC50 ranges of 3.66 to 8.25 mg/L for benzene, 1.16 to 22.42 mg/L for carbon tetrachloride, 0.11 to 1.20 mg/L for chlorobenzene, 2.03 to > 68 mg/L for chloroform, 3.01 to 5.56 mg/L …
Aquaculture In Cooling Water Recirculated From A Generating Plant, John G. Woiwode, Ira R. Adelman
Aquaculture In Cooling Water Recirculated From A Generating Plant, John G. Woiwode, Ira R. Adelman
Journal of the Minnesota Academy of Science
Recirculating cooling water from an electric generating plant accumulated dissolved and suspended solids up to ten times that of the make-up water from the Mississippi River. Channel catfish (lctalurus punctatus) and tilapia (Tilapia mossambica) were grown In the cooling water, in clear well water, and in a mixture of the two for seven months as part of an investigation of the use of cooling water for commercial aquaculture. Health of both species was generally excellent in test and control waters; growth was commercially acceptable; bioaccumulation of contaminants was negligible. Organoleptic taste quality was not acceptable, although the cause of the …

Resource Management Thrusts And Opportunities: National Parks And Wildlife Refuges, G. Ray Arnett
United States Fish and Wildlife Service: Publications
Well, it's been an interesting year. Somehow, it got to be very convenient for some folks to misconstrue what the Secretary had said. Some of those folks just seemed determined to make James Watt a household name-and they succeeded. And those same folks succeeded, too, in increasing the membership roles of a few of the environmental groups. But I don't think they succeeded very well in listening to and understanding what the Secretary said a year ago .... So, as succinctly and plainly as possible, I will spell out again that the goals of this Administration weren't designed to create …
Effects Of Increased Human Populations On Wildlife Resources Of The Kenai Peninsula, Alaska, Edward E. Bangs, Ted H. Spraker, Theodore N. Bailey, Vernon D. Berns

In this paper, we will discuss what has occurred to several wildlife populations on the Kenai Peninsula as the human population increased. By discussing historical impacts, management techniques, and potential human impacts, we intend to show the significance of what occurred and may occur as human populations expand, both on the Kenai and in Alaska.
Status Of Alaska Sea Otter Populations And Developing Conflicts With Fisheries, Ancel M. Johnson
Status Of Alaska Sea Otter Populations And Developing Conflicts With Fisheries, Ancel M. Johnson
United States Fish and Wildlife Service: Publications
Although sea otters (Enhydra lutris) have been a relatively insignificant resource in Alaska during the twentieth century, the situation is changing. Remnant populations that recolonized most of their historic range are becoming recognized as a potentially valuable economic resource and as a competitor with some important shellfish fisheries. It is appropriate that sea otters should again become an important Alaskan resource because they were so significant in the initial exploration and settlement of Alaska by non-natives. In this paper I review changes in distribution and population abundance since 1740, recent changes in human attitudes toward sea otters, and …

To many, the principal role of wildlife agencies in public and private resource development has been that of impact mitigation. With known or pending habitat damage, biologists have to develop mitigation or compensation plans. Unfortunately, once in a mitigation framework, they are in a no-win situation, seeking remedial action at best. Yet, the potential exists for cooperative project planning, thereby facilitating mitigation of impacts before they occur, and enhancement of environmental amenities through project development. In fact, such planning is mandated by federal legislation (e.g., National Environmental Policy Act, Fish and Wildlife Coordination Act, Outdoor Recreation Act, etc.).

Development And Use Of A Habitat Gradient Model To Evaluate Wildlife Habitat, Henry L. Short
Development And Use Of A Habitat Gradient Model To Evaluate Wildlife Habitat, Henry L. Short
United States Fish and Wildlife Service: Publications
Ecologists and wildlife managers are increasingly confronted with the problems of predicting the value of surface cover as wildlife habitat and developing management alternatives to offset wildlife values lost because of land-use change. These problems have become urgent and more acute because of increased demand for products from the land and diminished fiscal and manpower resources for obtaining meaningful environmental information for the decision maker. This paper describes a relatively rapid, simple, and quantitative process for evaluating the quality of an area as wildlife habitat.

Fishery Report No 55 - The Western Rock Lobster Fishery 1961 - 1971, G. R. Morgan, E H. Barker
Fisheries Research Reports
The fishery for the western rock lobster, Panulinus cygnus is one of the most important single fisheries in Australia and one of the major rock lobster fisheries of the world with catches in recent years averaging some 8000 tonnes annually. The history of the commercial fishery extends back to 1944/45 factory when a canning was opened at the Abrolhos Islands (Figure 1) with a view to supplying the Australian armed forces. After the World war, an export market for fresh frozen rock lobster tails was quickly established in the U.S.A. and the industry, sharing in the advantages of postwar reconstruction, …

Fisheries Report No 50 - Feasibility Trawling Activities In The Great Australian Bight By The Korean Trawlers Dong Ban 91 And Dong Won 509 During The Period 15.11.79 To 12.1.80, Michael H. Walker, Stuart J. Blight, Gerald M. Cliff
Fisheries Research Reports
Four Korean fishing trawlers operated in Western Australian waters, largely on the Northwest shelf, during 1979 under State/Commonwealth feasibility fishing arrangements. Two of these vessels, Dong Bang 91 and Dong Won 509, were given permission by Government, late in 1979, to conduct demersal trawling operations in the Great Australian Bight between longitudes 116°£ to 138°E and outside of 12 miles from shore.
Two observers from the Western Australian Department of Fisheries and Wildlife were involved with monitoring the activities of these vessels at sea in the Bight.
This report describes the operations of these Korean vessels in detail and represents …

Fisheries Report No 51 - 'Taiyo Maru 71" Demersal Trawling Cruise In Western Australian Coastal Waters South Of 21 S, July-September, 1979, D. I. Heald, M. H. Walker
Fisheries Research Reports
A Japanese demersal trawler, 'Taiyo Maru 771' was given special permission to conduct exploratory trawling in the period 73.7.79-16.9.79 off the Western Australian coast between 21°S Latitude and 35°30'S Latitude, an area which partly overlapped the fishing grounds for the western rock Lobster. The vessel was required to complete a catch, fishing effort and species composition log book issued by the Commonweath Department of Primary Industry. Two Western Australian Department of Fisheries and Wildlife observers on board monitored fishing operations for the entire duration of the cause and undertook research.
Details of each trawl conducted are given and discussed. Catch …

Fisheries Report No 57 - Exploratory Fishing For Spanish Mackerel In Waters Off Western Australia During The Period June 16 To October 16, 1981, K. Donohue, P. Edsall, J. Robins, R. Tregonning
Fisheries Research Reports
The results of catching Spanish mackerel (Scomberomorus commerson) by gillnet and troll lines during a survey extending from June 16 to October 16 1981 are presented.
The catch rate of mackerel obtained by trolling with six lines was found to be 14.35 times greater than that by gillnet, measuring 0.75 miles in length.
From the results presented, a professional fisherman should be able to assess the economic viability of fishing commercially for Spanish mackerel.
Analysis of biometrial and biological data on fish caught allowed determination of (a) length/weight relationship of (i) Spanish mackerel (ii) wahoo (Acanthocybium solandri); (b) sex ratios …
Wildlife Values Versus Human Recreation: Ruby Lake National Wildlife Refuge, Stephen H. Bouffard
Wildlife Values Versus Human Recreation: Ruby Lake National Wildlife Refuge, Stephen H. Bouffard
United States Fish and Wildlife Service: Publications
Expanding human populations are making increased recreational demands on National Wildlife Refuges (NWR). The U.S Fish and Wildlife Service (FWS) is trying to accommodate these demands whenever possible. An important, but not primary objective of NWRs is to provide for various public uses, including recreation (U .S. Fish and Wildlife Service 1976a). The Refuge Recreation Act of 1962 (16 U.S.C. 460K-460K-4) authorizes the FWS to allow recreational uses on NWRs, National Fish Hatcheries and similar lands. This act specifies that all recreational uses must be secondary to the primary purpose of the refuge. While most refuge recreation programs do not …

United States Fish and Wildlife Service: Publications
Wildlife managers have long recognized that management goals must be constrained by the availability and suitability of habitat. This recognition, combined with ever increasing land development pressures, has resulted in environmental legislation emphasizing systematic approaches to collection and analysis of habitat information. Wildlife planners have responded with a variety of approaches to the development of models that quantify habitat requirements.

Conservation Measures In The Interim Fishery Management Plan For Atlantic Groundfish, Andrew P. Matykiewicz
Conservation Measures In The Interim Fishery Management Plan For Atlantic Groundfish, Andrew P. Matykiewicz
Marine Affairs Theses and Major Papers
The conservation measures used in the Interim Fishery Management Plan for Atlantic Groundfish (IFMP) were analyzed. The management techniques used include a minimum mesh size, minimum fish size and haddock spawning area closure. However the mesh regulation does not adequately address the IFMP conservation objectives. Without amendment, the IFMP cannot prevent overfishing as it is required to do by the Magnuson Fishery Conservation and Management Act (MFCMA). The use of a non-numeric Optimum Yield (OI) for groundfish is inappropriate without a definition of overfishing and without a contingency plan to prevent overfishing.
California's Central Valley Wintering Waterfowl: Concerns And Challenges, David S. Gilmer, Michael R. Miller, Richard D. Bauer, John R. Ledonne
California's Central Valley Wintering Waterfowl: Concerns And Challenges, David S. Gilmer, Michael R. Miller, Richard D. Bauer, John R. Ledonne
United States Fish and Wildlife Service: Publications
Few places on the North American continent can boast of the concentrations of migratory birds that winter in the Central Valley of California. Long before agriculture and industrialization came west, this great valley served as a major wintering ground for millions of migratory birds. Fall flights of waterfowl, shorebirds, waders, raptors, and passerines returned annually to inhabit the vast wetland, riparian, and grassland habitats which covered the valley floor (Dasmann 1966, Bakker 1971).
Major changes in the Central Valley during the last century have profoundly influenced its physical and biological features. Wetland, riparian, and grassland habitats have been devastated by …

Current Status And Management Challenges For Tule White-Fronted Geese, Daniel E. Timm, Michael L. Wege, David S. Gilmer
United States Fish and Wildlife Service: Publications
Since large, dark tule white-fronted geese (Anser albifrons gam belli Hartlaub) were first described in Texas over a century ago by Hartlaub (1852), and again 65 years later in California by Swarth and Bryant (1917), tule geese have been the subject of at least 14 studies in California and 8 attempts to locate summering birds in the Artic. Central questions of these efforts have been: Is the tule goose a distinct subspecies? What is their range and population size? How can the birds be identified? and What threatens their existence?
The purpose of this paper is to present the …
The Influence Of Habitat Variation On The Morphology And Physiology Of Plethodon Wehrlei (Fowler And Dunn) In West Virginia, Sharon Kay Gross
The Influence Of Habitat Variation On The Morphology And Physiology Of Plethodon Wehrlei (Fowler And Dunn) In West Virginia, Sharon Kay Gross
Theses, Dissertations and Capstones
High elevation, low elevation and cave populations of Plethodon wehrlei (Fowler and Dunn) in West Virginia were compared to determine the influence of habitat variation on morphology and physiology. Discriminant analysis of 14 external morphological characters and 11 skeletal characters revealed a similar morphology for the three populations. Comparisons of critical thermal maxima showed a positive correlation to habitat temperature. Dehydration studies revealed that the high elevation population was more resistant and tolerant to water loss than the cave and low elevation populations.
A Distributional And Taxonomic Study Of The Adults Of The Family Hydropsychidae (Trichoptera) In West Virginia, Toni Ann Phillips
A Distributional And Taxonomic Study Of The Adults Of The Family Hydropsychidae (Trichoptera) In West Virginia, Toni Ann Phillips
Theses, Dissertations and Capstones
A survey of the adult Hydropsychiclae revealed 39 species, 14 of which were state records. The adult hydropsychids were collected from various locations throughout West Virginia. The most common species Hydropsychidae were Hydropsyche morosa, H. sparna, Cheumatopsyche analis, C. campyla, and Diplectrona modesta. Most of the species did not appear to be limited to any one particular drainage basin. Several species exhibited a preference for stream order (headwaters, middlereaches, large rivers). Aphropsyche monticola, Parapsyche apicalis, Cheumatopsvche wrighti, C, gyra, and Hydropsyche alhedra preferred the fast-flowing headwater streams in the higher elevations of the state. Macrostemum zebratum, Potomyia flava, Hydropsyche phalerata, …

Wild Commercial Fishery Of Arkansas, Tommie Crawford, Mike Freeze
Journal of the Arkansas Academy of Science
Arkansas' wild commercial fishery industry was surveyed to evaluate commercial fish products produced within the state. The total wild commercial catch for the period of 1 July 1980 to 30 June 1981 was approximately 8,680,124 kg with a value of $6,245,967. These values represent an increase of approximately 3% from the previous year. The bulk of the commercial harvest was made up of buffalo fishes (Ictiobus spp.), catfishes (Ictalurus spp), gars (Lepisosteus spp.) and carp (Cyprinus carpio). The number of commercial fishermen remained relatively unchanged from 1979-1980, with 3,843 licensed fishermen operating on the state's waterways. The number of licensed …
