The Effects Of Moulting On Muscle Fibre Characteristics Of The Yabby, Cherax Albidus, Tina Marie Lamey
The Effects Of Moulting On Muscle Fibre Characteristics Of The Yabby, Cherax Albidus, Tina Marie Lamey
Theses : Honours
In order to grow, crustaceans must shed their exoskeleton in a process known as "moulting'. Although this process is short and intermittent, it remains dominant over the life of a crustacean. Physiological changes in the period between moults (intermoult) are comparatively quiescent as opposed to the periods directly before and after the actual moult, known as premoult, and postmoult respectively (West, 1997). Moulting is associated with distinct physiological changes including the breakdown of muscle (Musgrove and Geddes, 1985). This muscle breakdown, known as atrophy is the diminution in size of the actual muscle mass and is very specific, occurring to …
Head Stabilisation During Running In Place Of Children With Varying Motor Proficiency Levels, Craig Atkins
Head Stabilisation During Running In Place Of Children With Varying Motor Proficiency Levels, Craig Atkins
Theses : Honours
Understanding head motion in children may contribute to development of effective strategies to improve coordination of children. The purpose of this study was to investigate head motion in children during stationary running. Twelve healthy 8-year-old children participated in this study and underwent a running proficiency test based on the Test for Gross Motor Proficiency (TGMO). Subjects were then videotaped while running for one minute "on the spot". Reflective markers were digitised for analysis of head motion relative to the external environment, and relative to the trunk. Resultant and component head angular velocities were calculated for each subject over five consecutive …
Population Dynamics Of The Southern Brown Bandicoot (Isoodon Obesulus) On Ellen Brook Reserve, Craig Pentland
Population Dynamics Of The Southern Brown Bandicoot (Isoodon Obesulus) On Ellen Brook Reserve, Craig Pentland
Theses : Honours
The small, enclosed section of Ellen Brook Reserve provided the unique opportunity to observe a population of southern-brown bandicoots (lsoodon obesulus) in the absence of exotic predators. The reserves small-enclosed size enabled it possible to trap the whole area (excluding the ephemeral swamps) and so emigration and immigration could be excluded. This enabled good population size estimates, and inferences on the loss of individuals due to mortality could be more strongly argued for. An understanding of the population structure, dynamics, size and density, and body condition of I. obesulus in Ellen Brook Reserve, will provide important information, for …
Myofibrillar Protein Composition Of Regenerating And Pristine Claw Closer Muscles Of The Yabby, Cherax Albidis, Lanelle Cutler
Myofibrillar Protein Composition Of Regenerating And Pristine Claw Closer Muscles Of The Yabby, Cherax Albidis, Lanelle Cutler
Theses : Honours
Yabbies have the ability to regenerate lost limbs. Loss of a limb results in the growth of a limb bud. Development of this new limb involves many developing stages until the new limb becomes morphologically and physiologically virtually indistinguishable from its predecessor. In the yabby, the claw becomes functional after the first moult when the dactyl becomes moveable. However, the muscle fibres are able to develop force and appear to be functioning before the dactyl becomes moveable and the claw is operational (West et al., 1995). This study aimed to document morphological stages of claw regeneration and determine sequence and …
Head Motion In Overarm Throwing For Children With Varying Levels Of Motor Proficiency, Kevin J. Netto
Head Motion In Overarm Throwing For Children With Varying Levels Of Motor Proficiency, Kevin J. Netto
Theses : Honours
The overarm throw has been classified as a fundamental motor skill that is the basis for a number of more complex sporting skills. There are a number of developmental stages over which a child progresses to the mature form of the skill. Control of the overarm throw, especially towards a target is very dependent on visual and vestibular information for successful execution. The quality of the information is, in tum, dependant on the head movement of the performer during the execution of the skill. It has been reported that head angular velocities above 350 degrees/second result in a degradation of …
Attitudes To Biotechnology And Genetically Modified Food : A Review, Juliana Rose Cannon
Attitudes To Biotechnology And Genetically Modified Food : A Review, Juliana Rose Cannon
Theses : Honours
Debate surrounds the introduction of new biotechnological applications such as genetically modified food (GMF). With this in mind a critical review of the debate, it's emerging themes, and approaches to measurement was undertaken. The intention of this review was to argue that while existing empirical measures have advanced our understanding of attitudes to GMF, they are limited both conceptually and methodologically. Overall, the validity and reliability of research support was compromised. Conceptually, attitudes to GMF were composed of a number of potential dimensions that have yet to be measured. Adherence to sound scale construction techniques may facilitate more reliable and …
