Spontaneous Discrimination Of Natural Stimuli By Chimpanzees (Pan Troglodytes), David A. Brown, Sarah T. Boysen

Sentience Collection

Six chimpanzees (Pan troglodytes) were presented with pairs of color photographic images of 5 different categories of animals (cat, chimp, gorilla, tiger, fish). The subjects responded to each pair using symbols for "same" and "different." Both within- and between-category discriminations were tested, and all chimpanzees classified the image pairs in accordance with the 5 experimenter-defined categories under conditions of nondifferential reinforcement. Although previous studies have demonstrated identification or discrimination of natural categories by nonhuman animals, subjects were typically differentially reinforced for their responses. The present findings demonstrate that chimpanzees can classify natural objects spontaneously and that such classifications may be …

Animal Minds And Animal Emotions, Marian Stamp Dawkins

Emotion Collection

The possibility of conscious experiences of emotions in non-human animals has been much less explored than that of conscious experiences associated with carrying out complex cognitive tasks. However, no great cognitive powers are needed to feel hunger or pain and it may be that the capacity to feel emotions is widespread in the animal kingdom. Since plants can show surprisingly sophisticated ‘‘choice’’ and ‘‘decision-making’’ mechanisms and yet we would not wish to imply that they are conscious, attribution of emotions to animals has to be done with care. Whether or not an animal possesses anticipatory mechanisms associated with positive and …

Fisheries Research Report No. 123 - Review Of Productivity Levels Of Western Australian Coastal And Estuarine Waters For Mariculture Planning Purposes, Alan Pearce, Stuart Helleren, Mark Marinelli, Fisheries Western Australia

Fisheries Research Reports

The measurement of chlorophyll-a (a simple estimate of phytoplankton biomass) is often used as an indicator of water quality. Chlorophyll measurements are relatively sparse for most of the Western Australian continental shelf, although there are areas such as the Perth metropolitan coastal zone, Wilson Inlet and the Albany harbours where some intensive studies have been undertaken.

This review of both published and unpublished chlorophyll concentrations in Western Australian waters has shown a high degree of variability in space (both horizontally and vertically) and time, and statistics on the seasonal distribution of chlorophyll have been derived for those regions with sufficient …

Fisheries Research Report No. 124 - The Evaluation Of A Recreational Fishing Stock Enhancement Trial Of Black Bream (Acanthopagrus Butcheri) In The Swan River, Western Australia, C J. Dibden, G. Jenkins, Gavin A. Sarre, R C J Lenanton, Suzanne G. Ayvazian

Fisheries Research Reports

During 1995, a study was undertaken to monitor and evaluate the recovery of Swan River black bream stock which had been supplemented with fish produced from a captive-breeding program. Fish were individually tagged and subsequently released into the Swan River. The objectives of the study were (a) to determine both the survival and the growth rate to a size at which hatchery-reared fish could enter the recreational fishery and (b) whether they could then be caught by the recreational fishers. Of the 767 fish released into the upper Swan River on 28 March 1995, 97 fish (12.6%) were recaptured to …

Predicted Land Use Changes In Agricultural Areas Of Wa And Resulting Impact On The Extent Of Dryland Salinity, C E. Mcconnell

Resource management technical reports

An assessment of current and possible future land use in Western Australia was undertaken as part of the National Land and Water Resources Audit. This data was used to assess the impact of land use change on the future extent of salinity. It was found that in some areas there is real capacity for changing land use to impact on recharge to the watertable.

"Bound Together . . . By Blood And Soul": Donald Davidson's Strategic Retreat Into The Myth Of Life In The Old South, Carol Pigg

Masters Theses & Specialist Projects

Donald Davidson has often been called stubborn because of his refusal to let go of the Southern past and in his insistence that his writings be based on and in the regional concerns that he saw as fundamental to all Southern literature. In many ways, Davidson's loyalty to the Agrarian and Fugitive causes, which are best defined in these groups interest in keeping the South's history alive and maintaining an agrarian lifestyle, is his greatest contribution to the Southern and American literary canon. Despite this fact, though, Davidson is now, as he was during his lifetime, ignored because of the …

Hemin-Binding Surface Protein From Bartonella Quintana, James A. Carroll, Sherry A. Coleman, Laura S. Smitherman, Michael F. Minnick

Biological Sciences Faculty Publications

Bartonella quintana, the agent of trench fever and a cause of endocarditis and bacillary angiomatosis in humans, has the highest reported in vitro hemin requirement for any bacterium. We determined that eight membrane-associated proteins from B. quintana bind hemin and that a similar to 25-kDa protein (HbpA) was the dominant hemin binding protein. Like many outer membrane proteins, HbpA partitions to the detergent phase of a Triton X-114 extract of the cell and is heat modifiable, displaying an apparent molecular mass shift from approximately 25 to 30 kDa when solubilized at 100 degreesC. Immunoblots of purified outer and inner membranes …

Characterization Of Borrelia Burgdorferi Blya And Blyb Proteins: A Prophage-Encoded Holin-Like System, Christopher J. Damman, Christian H. Eggers, D. Scott Samuels

Biological Sciences Faculty Publications

The conserved cp32 plasmid family of Borrelia burgdorferi was recently shown to be packaged into a bacteriophage particle (C. H. Eggers and D. S. Samuels, J. Bacteriol. 181:7308-7313, 1999), This plasmid encodes BlyA, a 7.4-kDa membrane-interactive protein, and BlyB, an accessory protein, which were previously proposed to comprise a hemolysis system. Our genetic and biochemical evidence suggests that this hypothesis is incorrect and that BlyA and BlyB function instead as a prophage-encoded holin or holin-like system for this newly described bacteriophage, An Escherichia coli mutant containing the blyAB locus that was defective for the normally cryptic host hemolysin SheA was …

Ecogeographic Aspects Of Greater Prairie-Chicken Leks In Southeastern Nebraska, Paul A. Johnsgard

Papers in Ornithology

An analysis of the distribution of 104 Greater Prairie-chicken leks in Pawnee and Johnson counties indicates that the birds favor using those mile-square sections having no more than two dwellings per section, ones that are located at least two miles from the nearest town, and at least a half-mile from the nearest lek. Relationships with the nearest water were not clear, but most leks were located at least a half-mile from it, perhaps reflecting a general avoidance of heavy cover during the display season.

A Synonym In The Genus Fluda (Araneae: Salticidae, G. B. Edwards

Insecta Mundi

Galiano (1971) revised the genus Fluda Peckham and Peckham 1892, and later updated the revision with additional descriptions, including a new species (Galiano 1986). In her original revision, she transferred Keyserlingella perdita Peckham and Peckham 1892, from Colombia, into the genus. This species was described from both sexes, but only the female was adequately illustrated. Galiano (1971) noted that Banks (1929) had examined only the female type of K. perdita when he described the Panamanian Fluda princeps from both sexes. She concluded that the male of K. perdita was lost subsequent to its description but prior to Banks examination. If …

Catalogue Of The Ectoparasitic Insects Of The Bats Of Argentina, Analia G. Autino, Guillermo E. Claps

Insecta Mundi

Abstract:Taxonomy and distribution of the ectoparasitic insects of bats from Argentina, are reviewed. Seventeen species of Diptera (six of Nycteribiidae and eleven of Streblidae), six species of Siphonaptera (four of Ischnopsyllidae, one of Pulicidae, and one of Stephanocircidae), and seven species of Hemiptera (Polyctenidae) are known presently for Argentina. The information was obtained by reviewing the literature and collecting in the field between 1989 and 1998. The specimens collected in the field were compared with the type material deposited at the Field Museum of Natural History (CHNM).

Variation At Tri- And Tetranucleotide Repeat Microsatellite Loci In The Fruit Bat Genus Cynopterus (Chiroptera: Pteropodidae), Jay F. Storz

Jay F. Storz Publications

There is considerable uncertainty surrounding the taxonomic relationship between Cynopterus sphinx and C. brachyotis, and the status of the many named forms within C. sphinx (Storz & Kunz 1999). Polymorphic microsatellite markers for cynopterine fruit bats would greatly aid efforts to elucidate species boundaries and genetic correlates of morphological variation within species. To assess levels of variation in C. sphinx and C. brachyotis, microsatellite genotypes were obtained for a total of 731 bats (620 C. sphinx and 111 C. brachyotis).

Identification And Characterization Of Zinc-Responsive Genes In Pseudomonas Fluorescens, Thomas L. Wilson

Masters Theses

Genes responsive to elevated concentrations of zinc were identified via transposon mutagenesis in the common soil bacterium, Pseudomonas fluorescens ATCC13525. Some of these genes were essential to maintain metal homeostasis in the bacterial cell. DNA sequences of the transposon-tagged genes were determined by DNA sequencing of arbitrary PCR products. DNA sequence analysis indicated that one gene was similar to P-type ATPases responsible for transporting metal ions out of the cell. The corresponding mutant was sensitive to zinc, cadmium, and lead indicating that this gene may be responsible for defending Pseudomonas fluorescens against these metal ions. Four zinc-induced genes shared similarity …

'Earlibrite' Strawberry, C. K. Chandler, D. E. Legard, David Dunigan, T. E. Crocker, C. A. Sims

Department of Plant Pathology: Faculty Publications

There is a need in west central Florida and other winter strawberry (Fragaria xananassa Duchesne) production areas for an early ripening cultivar to replace or be an alternative to 'Sweetcharlie' (Chandleretal., 1997a). 'Sweet Charlie' has benefitted the Florida strawberry industry through its relatively high production of fruit early in the season, when market prices are generally high. But the average fruit size is small, and the texture of its fruit is often soft, making shipment and shelf life of 'Sweet Charlie' problematic. 'Earlibrite' strawberry has produced high early-season (December through February) yields of large, flavorful fruit at the Univ. …
