Larval settlement and juvenile group dynamics in the domino damselfish (Dascyllus albisella)

Creator:: Booth, David J. (David John), 1958-
Abstract:: Patterns of settlement of larvae and population dynamics of juveniles are poorly known for coral reef fishes. During 1987 to 1989, I studied these phenomena in the domino damselfish (Dascyllus albisella), a species endemic to the Hawaiian Islands. Larvae settle onto branching coral heads as new recruits (10-15 mm in...

The roles of environmental constraints and aggression on male-female pairing in the coral-reef fish Gobiosoma evelynae

Creator:: Harding, Jeffrey A.
Abstract:: Early theoretical models for the evolution of male-female pairing were based largely on studies of birds. These models assumed that biparental care of eggs and young was an essential component of pairing. However, male-female pairing is also a relatively common social system in coral-reef fishes, and biparental care of young...

Patterns, causes, and consequences of clustering of individual territories of the threespot damselfish, Stegastes planifrons

Creator:: Meadows, Dwayne W.
Abstract:: The threespot damselfish, Stegastes planifrons, maintains individual territories that are clustered on coral patch reefs. My objective was to understand the effects of territory clustering on behavior and fitness. Fish with territories in the center of a cluster had (relative to edge fish): higher mating success (number of eggs), higher...

Geographic variation and mass mortality in the black abalone : the roles of development and ecology

Creator:: Tissot, Brian N. (Brian Nelson)
Abstract:: Studies of geographic variation are central to understanding ecological and evolutionary processes. Geographic variation in the shell of the black abalone (Halioth cracherodii), a marine intertidal gastropod, involves both clinal and local variation along the eastern Pacific coast in the number and size of tremata (=respiratory pores) on the shell....

Structural analysis of thermally inactivated nisin

Creator:: Musafija-Jeknic, Tamara
Abstract:: Nisin, an antimicrobial peptide used in food preservation was evaluated for thermal stability. Nisin retained antimicrobial activity after having been heated at 121°C for seven hours. Anhydrous nisin and concentrated nisin solutions (5-10 mg/ml) were still active after having been heated up to 190°C or 230°C. When exposed to high...

The use of lysozyme in winemaking : the interaction of lysozyme with wine and efficacy in preventing malolactic fermentation in Oregon Pinot noir and Chardonnay

Creator:: Green, Jeffery L.
Abstract:: Hen egg white lysozyme is a hydrolytic enzyme effective at preventing the growth of Gram positive bacteria by degrading the bacterial cell wall to a point of cell lysis. Investigating lysozyme as a processing tool in wine to control the growth of lactic acid bacteria and malolactic fermentation has significant...

Antioxidant potential of yeast containing beer

Creator:: Morris, Edward E.
Abstract:: It has been suggested that cellular damage from oxygen radicals is one of the processes leading to cardio-vascular disease and cancer. Natural antioxidants prevent uncontrolled oxidative reactions by decreasing molecular oxygen levels, scavenging chain-initiating and chain-propagating free radicals, chelating metals, or decomposing peroxides. Beer is rich in antioxidants, derived both...

Immobilization of hen egg white lysozyme by the sole histidine residue to polystyrene beads through peptide spacers

Creator:: Wu, Yawen
Abstract:: Lysozyme is a natural antimicrobial agent that is effective against many food spoilage and pathogenic microorganisms by disintegrating their cell walls. Immobilization of lysozyme has attractive applications for use in the food industry: (1) The enzyme could be readily separated from treated foods and beverages and re-used while the foods...

A study of nisin resistance in Listeria monocytogenes Scott A

Creator:: Ming, Xintian
Abstract:: Eight foodborne pathogenic and spoilage Gram-positive bacteria were evaluated for their spontaneous resistance frequencies to the peptide antimicrobial nisin. In brain heart infusion (BHI) medium, nisin resistance frequencies were in the range of l06 to l08 when exposed to nisin at concentrations 2 to 4 times the minimal inhibitory concentrations....

Lysozyme as an aid in preventing stuck wine fermentations

Creator:: Hetz, Uri
Abstract:: To provide a possible alternative for the antimicrobial action of sulfur dioxide in winemaking, and address the issue of stuck fermentations, I studied the efficacy of chicken lysozyme (EC 3.2.1.17) as an antimicrobial in grape juice. Two different forms of lysozyme were used: native lysozyme (NL), that is known to...
