An Investigation Of Captive Florida Manatee (Trichecus Manatus Latirostris) Behavior And Social Interactions, Jennifer Sadler Young
An Investigation Of Captive Florida Manatee (Trichecus Manatus Latirostris) Behavior And Social Interactions, Jennifer Sadler Young
Legacy ETDs
Human impacts such as pollution, habitat alteration, and boating have caused many injuries and deaths of the Florida manatee, Trichechus manutus latirostris. Rehabilitation centers have been established in Florida to help return sick or injured manatees back to the wild. Manatees that are released back to the wild after undergoing rehabilitation in captivity might lose some of their abilities to survive in the wild. A factor that might alter behavior in captive individuals was examined by determining if length of time spent in captivity influenced the behavior of manatees during rehabilitation. Even though all facilities follow similar guidelines, invariable …
The Reliability And Validity Of The Pacer For 3rd And 4th Grade Males, Jennifer A. Hinely
The Reliability And Validity Of The Pacer For 3rd And 4th Grade Males, Jennifer A. Hinely
Legacy ETDs
BACKGROUND: FITNESSGRAM recommends the use of the PACER, a 20-meter shuttle run, to assess the aerobic ability of children in physical education classes.
OBJECTIVES: To examine the reliability and validity of the PACER for 3rd and 4th grade males. In addition, the reliability and validity of the criterion-referenced standards will be examined.
METHODS: 22 students ran 3 trials of the FITNESSGRAM PACER while wearing the Cosmed K4b2 system.
RESULTS: From the 22 students, the intraclass correlation for the number of laps for trial 2 to trial 3 was 0.81. The reliability of the estimated VO2 from trial 2 to trial …
The Relationship Between Jealousy And Self-Esteem In Collegiate Athletes, Paula M. Parker
The Relationship Between Jealousy And Self-Esteem In Collegiate Athletes, Paula M. Parker
Legacy ETDs
Previous research has found contradictory results when examining the possible relationship between jealousy and self-esteem (Guerrero & Afifi, 1998, Mathes & Severa, 1981; Mikulincer, Bizman, & Aizenberg, 1989, Peretti & Pudowski, 1997; Stewart & Beatty, 1985; White, 1981). Jealousy has been most often researched in romantic relationships (Peretti & Pudowski, 1997; Salovey & Rodin, 1986) and social comparison situations (Bers & Rodin, 1984, Mikulincer, Bizman, & .Aizenberg, 1989). Few studies have examined jealousy in an athletic setting. Sport jealousy has received little attention because until recently, there was no reliable instrument to measure jealousy in sport. Pease (1987) investigated the …
Determining The Termination Percentage Of Heart Rate Maximum For Submaximal Testing, Julia A. Valentour
Determining The Termination Percentage Of Heart Rate Maximum For Submaximal Testing, Julia A. Valentour
Legacy ETDs
BACKGROUND: In the Fourth Edition of the American College of Sports Medicine's Guidelines for Exercise Testing and Prescription (1991). the protocol for the ACSM's submaximal bike test was to terminate the test at 65-70% of the age predicted maximal heart rate. In the Fifth Edition, this was changed to 85% of the age-predicted maximal heart rate.
OBJECTIVES: The purpose of this study was to find out, by using the ACSM submaximal cycle ergometer test (see Appendix A) if the 85% heart rate maximum termination provides a more accurate estimate of maximal aerobic capacity than the 70% heart rate maximum termination. …
The Prevalence Of Human Granulocytic Ehrlichiae In Ixodes Scapularis Ticks In Southeastern Georgia, Heather Anne Merten
The Prevalence Of Human Granulocytic Ehrlichiae In Ixodes Scapularis Ticks In Southeastern Georgia, Heather Anne Merten
Legacy ETDs
Human granulocytic ehrlichiosis (HGE) is a newly emerging, tick-borne zoonosis in North America. The agent that causes HGE is very similar to Ehrlichia phagocytophilia and Ehrlichia equi, but has yet to be classified as a separate species.
This study was carried out in order to determine the prevalence rate of HGE infection in blacklegged ticks (Ixodes scapularis) in insular and mainland sites in southeastern Georgia using nested PCR techniques. Four locations were studied representing 2 barrier islands and 2 mainland sites. We hypothesized that areas that have low levels of human disturbance and are somewhat isolated will …
A Comparative Study Of The Reproductive Biology Of Sympatric Morning Glories (Ipomoea-Convolvulaceae), Dexter R. Sowell Ii
A Comparative Study Of The Reproductive Biology Of Sympatric Morning Glories (Ipomoea-Convolvulaceae), Dexter R. Sowell Ii
Legacy ETDs
Despite the astounding diversity of flowering plants and of mobile organisms that serve as pollinators, sympatric co-flowering plants can potentially share pollinators with each other. This places two selection pressures on plants. First, plants compete for pollinators to visit their flowers and secondly, entice pollinators to be faithful (specialized) and visit only other members of their species. I tested whether sympatric co-flowering plants reduced their selection pressures via temporal partitioning or differential attraction of pollinators using six closely related, sympatric co-flowering morning glories (Ipomoea-Convolvulaceae).
Diurnal flower phenology tightly overlapped, which did not facilitate temporal partitioning of pollinators. However, …

Group Viii Spiroplasma Of Costa Rica, Kimberly M. Stewart
Legacy ETDs
Spiroplasma bacteria isolates are classified or identified through a series of serological tests that normally consists of screening, one-way deformation tests, cloning, antisera production, and reciprocal deformation tests. Serological tests on the spiroplasmas are followed by molecular analysis. The standard molecular analysis used for spiroplasmas has been 16S rRNA sequencing. The primary goal ofmy research was to evaluate serologically Group VIII spiroplasmas isolated from tropical Costa Rican tabanids (Diptera: Tabanidae) and to compare them to the temperate North American Group VIII spiroplasmas. A secondary goal was to evaluate both the temperate and tropical Group VIII strains by sequencing the 16S-23S …
