Florida Macrolichens As Potential Bioindicators Of Environmental Quality: A Baseline Study, Harry V. Neal

Retrospective Theses and Dissertations

Lichens have been used extensively and with considerable success as bioindicators of atmospheric pollution in North America and Europe for more than thirty years. Little research has followed in tropical and subtropical regions where population growth is rapid and environmental pressures unprecedented. However, taxa used as bioindicators in other studies and/or taxa having this potential, occur naturally in Central Florida. A new potential major source of pollution, the coal-fired Curtis H. Stanton Energy Center, is about to begin operation providing the opportunity to determine the extent of impact. Therefore, lichen monitoring sites have been established and the collection of baseline …

Multiple Trophic Levels In Soft-Bottom Communities, John A. Commito, William G. Ambrose Jr.

Environmental Studies Faculty Publications

In order to assess the general applicability of recent field experiments with predatory infauna, we searched the literature and found 48 well-documented cases of infaunal consumption by such predators. In 63 % of the cases detailed enough to make a determination, the predators ate other predators. Multiple trophic levels within the infauna are probably a common feature of many soft-bottom communities.

History Of Arcata Community Forest, Susie Van Kirk

Susie Van Kirk Papers

On 17 May 1955, dedication ceremonies for the Arcata Community Forest were held by the Arcata Redwood Circle of the Redwood Region Conservation Council, which sent out 2,500 invitations to the event. The first municipally owned forest in the State of California, Arcata's 6OO-acre Forest was to be "managed for the benefit of all the citizens of the city, with attention to watershed, recreation, timber management and other values (Humboldt Times, 15 May 1955).

How the land has been used and how it came into City ownership are the subjects of this paper, which recounts a history of public domain …

T-61 Use In The Euthanasia Of Domestic Animals: A Survey, Andrew N. Rowan

Veterinary Science and Medicine Collection

A variety of techniques have been proposed and employed for the killing of domestic animals but relatively few have survived as suitable agents for euthanasia-namely, the induction of painless, suffering-free death. Some agents, such as strychnine, curariform agents, or potassium salts cause suffering while others have other disadvantages. 'lbday, dogs and cats are commonly euthanatized with sodium pentobarbital or with T-61 which is a mixture of a central nervous system narcotic, a paralytic agent, and a local anesthetic. The use of T-61 was first reported in the United States in 1963 (Quin 1963). The substance gradually became more popular because …

Two Modal Action Patterns With A Continuous Temporal Distribution, Alan B. Bond, George W. Barlow, William Rogers

Papers in Behavior in Biological Sciences

Most methods of quantitative analysis of animal behavior assume that action patterns can be unambiguously classified into discrete, exclusive categories. This is not invariably the case. The digging behavior of the Midas cichlid (Cichlasoma citrinellum), for example, exhibits two functionally distinct modalities, scoop and pi&, that intergrade continuously in form but are separable probabilistically. We present a technique for analyzing such behaviors that provides a reliable basis for formulating and verifying categories and allows a quantitative assessment of functional dissimilarity.

Die meisten Methoden quantitativer Verhaltensanalysen setzen eindeutige Klassifizierung der Verhaltensweisen in sich wechselseitig ausschlieißende Kategorien voraus. Die sind …

Contaminant Transport Against A Slowly Moving Fluid : An Experimental Investigation, Surya Man Shakya

Theses

Leachate migration into groundwater from leaking lagoons, hazardous waste sites, solid waste disposal sites, etc. has recently become a major cause of groundwater pollution. A possible solution to prevent leachate migration into groundwater is to create a negative hydraulic gradient toward the site. This can be achieved by installing two parallel slurry trench cut-offs around the perimeter of a leaking lagoon and by filling it with water. The water und-er the influence of positive hydraulic gradient will move toward the site and will finally find its way on the surface of the lagoon. Along with the flow of water, the …

Dummy-Elicited Aggressive Behavior In The Polychromatic Midas Cichlid, George W. Barlow, William Rogers, Alan B. Bond

Alan Bond Publications

Aggressive responses of 12 individuals of the polychromatic Midas cichlid Cichlasoma citrinellum were tested with five different sizes of neutrally colored (spot pattern) life-like dummies. The dummies were presented daily over six days, for one minute apiece, in a balanced design. Color (gold or normal morph) and sex of the subjects were varied independently. The attacks and threats at the dummies were positively correlated in their occurrence so they were combined to yield an aggregate measure of aggression. Attacks on blinded juveniles, five minutes before and five minutes after viewing a dummy, were analyzed to test for the occurrence of …

Effect Of Edwardsiella Ictaluri Infection On Plasma Corticosterone Levels In Channel Catfish (Ictalurus Punctatus), Janice L. Cooper, Stanley N. David, John K. Beadles

Journal of the Arkansas Academy of Science

Channel catfish (Ictalurus punctatus) were innoculated with a new host specific bacterium, Edwardsiella ictaluri, to observe the influence of bacterial infection on plasma corticosterone levels at various temperatures. The fish were innoculated intraperitoneally. The infected fish were separated from the controls. Plasma corticosterone concentrations were determined by radioimmunoassay. The plasma corticosterone concentrations in non-innoculated catfish were about 6.15 ng/ml and nearly 5.63 ng/ml in the infected fish. The lower level of the hormone in the infected catfish was not significantly different from the control level. High temperature was a stress factor which increased plasma corticosterone levels whereas E. ictaluri retarded …

The Effects Of Dredged Materials On The Copeod, Acartia Tonsa, Renee Suzanne Crouch

Biological Sciences Theses & Dissertations

A study was conducted to determine the potential impact of open ocean disposal of sediments dredged from a highly industrialized seaport. Sediments from three potential dredge sites along the Southern Branch of the Elizabeth River, Hampton Roads, Virginia were evaluated for acute toxicity. The suspended particulate fractions of dredged materials were tested in a series of 96-hour, static bioassays using the calanoid copepod, Acartia tonsa Dana. Significant mortalities were observed for all three sites with the sediments from the most heavily industrialized site producing immediate and severe mortality. Analysis of results indicates that mortality was highly related to the volatile …

Foraging Ecology Of Temperate-Zone And Tropical Woodpeckers, Robert A. Askins

Biology Faculty Publications

The foraging behavior of 11 species of woodpeckers in Guatemala, Maryland, and Minnesota was studied in order to test the seasonal stability hypothesis. This hypothesis predicts that specialization and species richness should be no greater for tropical wood-excavators than for those in the temperate zone because wood-excavators in both regions are buffered against seasonal change. Niche breadth values for six variables that describe foraging methods and perches were calculated by two methods. Unweighted niche breadth values were similar for tropical and temperate woodpeckers for all variables except foraging techniques; in this case the temperate species are more specialized. With weighted …

Psychological Aspects Of Slaughter: Reactions Of College Students To Killing And Butchering Cattle And Hogs, Harold A. Herzog, Sandy Mcgee

International Journal for the Study of Animal Problems

This study examined college students' reactions to slaughtering cattle and hogs as part of their jobs on a college work crew. The 27 students were surveyed on attitudes containing items toward slaughtering animals and toward different uses of animals. Nineteen were later interviewed. Some aspects of slaughtering were reported to be more bothersome than others. There was a relationship between the subjects' experience in slaughtering, general attitudes toward various uses of animals, and their responses to several of the items on the questionnaire. The perceived benefits of the slaughtering experience and the justification for killing domestic animals for food are …

The North American Black Duck (Anas Rubripes): A Case Study Of 28 Years Of Failure In American Wildlife Management, John W. Grandy

Conservation Collection

A scientific and technical analysis is presented of the factors which may have been primarily responsible for an estimated 60% decline in the black duck (Anas rubripes) population since 1955. The analyses presented show that the U.S. Fish and Wildlife Service (FWS), the management agency responsible for waterfowl management in the United States, has recognized the population decline, that the FWS's own experts have consistently recognized that hunting is the most likely cause of the population decline, and that hunting is the only mortality factor which wildlife managers can control in the practical sense. Using FWS information, the author shows, …

Cranes Of The World: References, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

The following list of more than 400 references is by no means a complete bibliography of cranes, but does include a few titles that for various reasons were not specifically cited in the text. Walkinshaw's (1973) monograph contains a large number of citations not found in the present list, and he additionally has recently (1981c) updated and supplemented his earlier bibliography. All told, his two citation lists include nearly 2,500 citations. Nearly 40 percent of the 1973 list deals with the whooping crane, 20 percent with the sandhill crane, 15 percent with the Eurasian crane, and 8 percent with the …

The Transmission Of Learned Behavior: An Observational Study Of Father-Child Interactions During Fishing, Judy Diamond, Alan B. Bond

Papers in Behavior in Biological Sciences

Mechanisms of transmission of learned behavior were described in terms of the behavioral interactions between fathers and their children as they fished from a pier on Maryland’s Eastern Shore. Verbal and nonverbal behaviors were analyzed using hierarchical cluster analysis and the patterns of association in the behavioral repertoire were described in detail. Groupings of associated behaviors ranged from clusters suggestive of modeling or simple showing to complex combinations of behaviors involved in teaching. There were indications that the transmission behaviors varied with the content of the transmitted information and the role of the performer. Role differentiation in the transmission behaviors …

Habitat Selection Related To Resource Availability Among Cavity-Nesting Birds, Timothy Brush

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Variation in snag species and abundance appeared to explain most of the habitat selection patterns observed in five cavity-nesting riparian species over a three-year period. All species except Ash-throated Flycatchers were most common in areas with cottonwood or willow snags, which have relatively soft wood and are preferred nest sites. Classification of habitats on the basis of nest-site characteristics was useful and should be considered in other habitat selection studies.

The Interactive Effects Of Water Salinity And Management On Symbiotic Nitrogen Fixation In Alfalfa, Thomas J. Keck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A greenhouse study was conducted to assess the interactive effects of three irrigation water salinity levels (1.0, 3.0, and 9.0 mmho/cm) and three quantities of water app lied per irrigation (120, 240, 360 ml) on plant growth and nitrogen fixation by alfalfa (Medicago sativa L. cv. Resistador). Harvest dates corresponded to 10, 30, and 50 days after the initiation of salt and water treatments which were started after nodulation had been established in young plants.

Alfalfa top growth was limited by both salt and water stresses. Irrigation water salinity had a greater effect on top growth than root growth …

An Evaluation Of Deschampsia Caespitosa (L.) Beauv Populations For Metal Tolerances And Ecotypic Variation At Climax, Colorado, Paul Ellsworth Pratt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Four populations of Deschampsia caespitosa (L.) Beauv (a Poaceae species), growing on disturbed and undisturbed sites at Climax, Colorado, were examined for metal tolerances (Zn, Cu, Pb, Al). Root growth assessments on parent plant and offspring material for each population were conducted using nutrient solutions containing elevated levels of Zn, Cu, Pb, or Al. Seed germination and seedling survival tests for each population were conducted on both alpine topsoil and mine spoil material.

Evidence is presented that supports the hypothesis that ecotypic variation exists within Deschampsia caespitosa and that this variation has allowed certain Deschampsia populations to become successfully established …
