Competition between earthworms in high rainfall pastures in the Mt. Lofty Ranges, South Australia

Dalby, Paul Reginald. January 1996 (has links) (PDF)
Copy of author's previously published work inserted. Bibliography: leaves 261-306. The objectives of the project were: i. to determine whether there are competitive interactions between Aporrectodea trapezoides and A. caliginosa and A. rosea.--ii. to investigate compeditive interactions between A. calignosa, Microscolex dubius and A. trapezoides.--iii . to determine the likely impact of A. longa on soil fauna, especially the native earthworm, Gemascolex lateralis, in native ecosystems.

A comparison of the effects of grazing and mining on vegetation of selected parts of northern South Australia

Badman, Francis John. January 2002 (has links) (PDF)
Accompanying CD-ROM inside back cover, includes Appendices. Bibliography: leaves 242-266. This thesis examines the effects on vegetation at selected sites in northern South Australia of excluding various herbivores over a four and a half year period and of two intense but controlled grazing pulses over a six month period followed by an 18 month recovery period in a dune-swale land system. These changes are compared with changes recorded over an 11-year period at the Olympic Dam mine site. It found that short-term changes in vegetation revealed by ordination of periodical cover, density and species richness, are attributable to the periodicity of rainfall and that, under present grazing regimes, rainfall effects override grazing effects. Differences between the effects of sheep and cattle hoof damage are worthy of further investigation, as is the impact of kangaroo grazing. These two factors may have important implications for the management of Australian rangelands. System requirements for accompanying CD-ROM: IBM compatible computer with Pentium processor or higher and Windows 95, 98 or NT ; 4 MB or RAM. Other software: Acrobat Adobe Reader.

Ecophysiology and production ecology of the kelp ecklonia radiata (C.Agardh) J.Agardh, at West Island, South Australia / Victoria Anne Fairhead.

Fairhead, Victoria A. January 2002 (has links)
"November 2001" / Bibliography: leaves 132-156. / xii, 166 leaves : ill. (some col.), plates (col.) ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / Focusses on the ecophysiology of Ecklonia radiata and quantifies its carbon contribution to further elucidate E. radiata's role in the nearshore marine environment. The photosynthesis-irradiance response of E. radiata was investigated in situ throughout the year and across the dept profile. A clear seasonal change in photokinetic parameters was detected and provided strong evidence of a seasonal acclimation response. Changes in photokinetic parameters across the depth profile were less pronounced and a significant decline in productivity occurred at deeper depths. The acclimation state of E radiata did alter across the depth profile. / Thesis (Ph.D.)--University of Adelaide, Dept. of Environmental Biology, 2002
