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 …

Dynamic Effects Of Food Magnitude On Interim-Terminal Interaction, Alliston K. Reid, Robert H.I. Dale
Dynamic Effects Of Food Magnitude On Interim-Terminal Interaction, Alliston K. Reid, Robert H.I. Dale
Scholarship and Professional Work - LAS
We tested the assumption of a facilitatory relation between periodic food presentation and schedule-induced drinking by examination of (a) elicited drinking, (b) drinking in anticipation of food delivery, and (c) possible indirect effects of food delivery on drinking. We exposed rats to a fixed-time 60-second schedule in which interfood intervals ended in either one or four food pellets with equal probability. In Phases 1 and 3, a stimulus signaled the magnitude of upcoming food presentation. In Phase 2, the stimulus was eliminated. Changes in drinking and "head-in-feeder" distributions within interfood intervals demonstrated that head-in-feeder was controlled directly by food presentation, …
Water Quality Trends In The Las Vegas Wash Wetlands, F. A. Morris, L. J. Paulson
Water Quality Trends In The Las Vegas Wash Wetlands, F. A. Morris, L. J. Paulson
Publications (WR)
The Las Vegas Wash is a wetlands ecosystem that acts to buffer the effects of wastewater discharges on the receiving waters of Lake Mead. The wash is the terminus for the 4,144 km2 Las Vegas Valley drainage basin, emptying into Las Vegas Bay of Lake Mead (Colorado River). It is in the northern Mojave desert, which receives an average of only 10 cm of rainfall annually. The Las Vegas Wash is technically an artificial wetland supported almost entirely by the perennial flows from sewage treatment plants. These flows contribute an average of 3-7 t of nutrients (nitrogen and phosphorus) and …
The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson
The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson
Publications (WR)
The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …
Environmental Correlates Of Hermatypic Coral (Montastrea Annularis) Growth On The East Flower Gardens Bank, Northwest Gulf Of Mexico, Richard E. Dodge, Judith C. Lang
Environmental Correlates Of Hermatypic Coral (Montastrea Annularis) Growth On The East Flower Gardens Bank, Northwest Gulf Of Mexico, Richard E. Dodge, Judith C. Lang
Marine & Environmental Sciences Faculty Articles
Time series of annual linear growth increments from 12 Montastrea annularis (E. and S.) collected at the East Flower Gardens Bank reef in the northwestern Gulf of Mexico have a common pattern. This is best expressed in an index master chronology (average by year of the annual percentage deviations from the mean of each coral.)
Comparisons with time series of environmental data indicate that coral extension rates vary positively with seasonal (February through May - 4 months) surface water temperature and negatively with annual discharge of the Atchafalaya River. We propose that secular variations of water temperature and other parameters …
Curidia Debrogania, A New Genus And Species Of Amphipod (Crustacea: Ochlesidae) From The Barrier Reefs Of Belize, Central America, James Darwin Thomas
Curidia Debrogania, A New Genus And Species Of Amphipod (Crustacea: Ochlesidae) From The Barrier Reefs Of Belize, Central America, James Darwin Thomas
Marine & Environmental Sciences Faculty Articles
The family Ochlesidae is amended to include the new genus Curidia, which differs from all other members by possessing maxiIIipedal palps. Curidia debrogania is described and compared to other genera and species within the family Ochlesidae.
Curidia debrogania is plesiomorphic by possession of maxillipedal palps, suggesting this member of the small, cryptic family might have originated in the tropical Western Atlantic. Distribution records and ecological notes are included.
Tumor Cell Glutathione Metabolism: Therapeutic Implications, Bradley Alan Arrick
Tumor Cell Glutathione Metabolism: Therapeutic Implications, Bradley Alan Arrick
Student Theses and Dissertations
In response to oxidative injury murine tumors depend upon the GSH oxidation-reduction cycle. The susceptibility of tumor cells to lysis by a flux of H2O2, such as generated by granulocytes or activated macrophages, or by the enzyme glucose oxidase, was augmented by interference with the GSH redox cycle. Depletion of tumor cell GSH was by 2 methods: incubation of cells with buthionine sulfoximine (BSO), a nontoxic inhibitor of GSH synthesis, or with 1-chloro-2,4-dinitrobenzene, a substrate for GSH S-transferase. Sensitization to oxidative cytolysis correlated with GSH depletion by either method by the critera of both dose-response and …
Genetic And Biochemical Analysis Of The Bryan Strain Of Rous Sarcoma Virus, Teena Louise Lerner
Genetic And Biochemical Analysis Of The Bryan Strain Of Rous Sarcoma Virus, Teena Louise Lerner
Student Theses and Dissertations
Integration of Rous sarcoma virus DNA into its host genome was analyzed under conditions where secondary integration via virus spread was inhibited. This was accomplished by using the noninfectious pol-, env- alpha variant of the Bryan high titer strain of Rous sarcoma virus (BH-RSV). Twelve independent BHRSV-transformed chicken embryo fibroblast clones were obtained and the provirus-cell junction fragments were mapped by restriction endonuclease cleavage and Southern blotting analyses. We found that expression of the viral genes could occur after proviral integration at many sites on the chicken genome and that there was no apparent preference for specific …
Structure-Function Relationships Of Elements Of The Bacteriophage F1 Genome, Phyllis Barbara Moses
Structure-Function Relationships Of Elements Of The Bacteriophage F1 Genome, Phyllis Barbara Moses
Student Theses and Dissertations
Expression of the ten genes on the small filamentous phage f1 genome must be closely regulated during the infection cycle, since this nonlytic coliphage lives in delicate balance with its host. The sequence and context requirements of specific regions involved in f1 mRNA metabolism were investigated by: 1) relocation of an intact transcription unit on the phage genome; 2) construction of a hybrid E. coli-f1 transcription unit which could be studied in a phage or plasmid context; 3) identification and characterization of a rho-dependent transcription termination signal in f1 by cloning it between the promoter and gene of an E. …
Sequence And Functional Structures Of The Extrachromosomal Rdna Minichromosome Of Physrum Polycephalum, Gerald Ray Campbell
Sequence And Functional Structures Of The Extrachromosomal Rdna Minichromosome Of Physrum Polycephalum, Gerald Ray Campbell
Student Theses and Dissertations
The ribosomal RNA genes of Physarum polycephalum are encoded on multiple copies of linear, palindromic extrachromosomal DNA molecules (rDNA), which have been isolated both as a satellite DNA molecule, and as a "minichromosome" with associated chromatin proteins. The genes coding for the 19 S, 26 S, and 5.8 S rRNAs are transcribed as a single, large precursor molecule, beginning nearer the center of the palindrome and transcribing outward. The genes are in the order 19 - 5.8 - 26, and the 26 S gene contains two intervening sequences. The intervening sequences are transcribed, and later excised out. The region of …
Regulation Of Expression Of A Retroviral Transforming Gene And Its Cellular Homolog, Bernard Mathey-Prevot
Regulation Of Expression Of A Retroviral Transforming Gene And Its Cellular Homolog, Bernard Mathey-Prevot
Student Theses and Dissertations
This thesis has focused on the avian Fujinami sarcoma virus (FSV) and its role in transformation. Specifically, it included the biochemical characterization of temperature-sensitive (ts) mutants of FSV, the identification of the product of a cellular gene homologous to the transforming gene of FSV, and the isolation and characterization of phenotypic revertants of rat cells transformed by FSV. Analysis of the defect of the two ts mutants of FSV revealed that P130 is the transforming protein of FSV and that its kinase activity plays a crucial role in cell transformation by this virus. v-fps, the transforming gene of FSV is …

A Note On The Reproductive Season Of The Carolina Marsh Clam Polymesoda Caroliniana (Bosc) In An Irregularly Flooded Mississippi Marsh, Courtney T. Hackney
A Note On The Reproductive Season Of The Carolina Marsh Clam Polymesoda Caroliniana (Bosc) In An Irregularly Flooded Mississippi Marsh, Courtney T. Hackney
Gulf and Caribbean Research
The gonadal development of Polymesoda caroliniana in an irregularly flooded, brackish marsh was followed for 13 months. Ripe individuals (condition prior to spawning) were found in May, July, August, and October, suggesting either an extended period of spawning or three discrete spawning periods. This pattern is different from another study of P. caroliniana in a more flooded habitat.
The observed gonadal condition correlates with the presence of newly recruited clams in the marsh during most of the year, but failed to explain a pulse of juveniles found in February. The different reproductive pattern observed in this brackish marsh may be …

Mouthparts for A. holmesi are described, illustrated, and compared with those of A. verrilli from the northeastern coast of the United States.
Effects On Iron And Cobalt On Methane Production From Dairy Cattle Manure, Mark E. Himes
Effects On Iron And Cobalt On Methane Production From Dairy Cattle Manure, Mark E. Himes
Retrospective Theses and Dissertations
The effects of iron and cobalt on methanogenesis from dairy cattle manure were studied. Four-liter digestors with 3-liter working volumes were charged daily with dairy manure (4.5% W/V volatile solids) to achieve a 3-day retention time. Digestors were incubated at 37°C and pH 7.0 on a rotary shaker. Duplicate digestors were maintained under the following parameters: controls (no ions added), Co++ at 4.958 mg/liter, Fe++ at 20.64 mg/liter and Fe++ and Co++ at above stated final digestor concentrations.
Significantly higher production of biogas and methane occurred with the addition of iron (p = .05). Iron-amended digestors …

Scaring Of Carrion Crows (Corvus Corone Corone) By Species-Specific Distress Calls And Suspended Bodies Of Dead Crows, Luzia Naef-Daenzer
Scaring Of Carrion Crows (Corvus Corone Corone) By Species-Specific Distress Calls And Suspended Bodies Of Dead Crows, Luzia Naef-Daenzer
Bird Control Seminars Proceedings
In Switzerland, carrion crows can cause considerable damage to sprouting corn fields when feeding on the germinated corn. I tried to evaluate a method to prevent these damages. The use of species-specific distress calls, for the first time described by Frings and Jumber (1954), seemed to be the most promising method. Agronomes and biologists have applied it in field studies to several different bird species causing damage in agriculture and on airports (e.g., Gramet, 1962; Brough, 1968). However, the literature either describes single actions or several different scaring devices being used together. To be able to judge the method, quantitative …
Introduction To The Symposium On Imported Fire Ants, Southeastern Branch, Entomological Society Of America, January 26, 1982, C. S. Lofgren
Introduction To The Symposium On Imported Fire Ants, Southeastern Branch, Entomological Society Of America, January 26, 1982, C. S. Lofgren
Entomology Papers from Other Sources
While there have been many exotic insect pests inadvertently introduced into the United States, only a few have had the dramatic impact that the imported fire ants (Solenopsis invicta Buren and S. richteri Forel) have had on the southern states. Certainly this is understandable to anyone who has seen their small child receiving dozens of fiery injections of venom or to a farmer who suddenly realizes that his lush verdant pasture has become the mound construction site for hundreds of colonies of fire ants, each with 100,000 to 200,000 workers who are willing to attack anyone who disturbs their …
