A Genetic Classification Of Floodplains, G C. Nanson, J C. Croke Jan 1992

A Genetic Classification Of Floodplains, G C. Nanson, J C. Croke

Faculty of Science, Medicine and Health - Papers: part A

Floodplains are formed by a complex interaction of fluvial processes but their character and evolution is essentially the product of stream power and sediment character. The relation between a stream's ability to entrain and transport sediment and the erosional resistance of floodplain alluvium that forms the channel boundary provides the basis for a genetic classification of floodplains. Three classes are recognised: (1) high-energy non-cohesive; (2) medium-energy non-cohesive; and (3) low-energy cohesive floodplains. Thirteen derivative orders and suborders, ranging from confined, coarse-grained, non-cohesive floodplains in high-energy environments to unconfined fine-grained cohesive floodplains in low-energy environments, are defined on the basis ...


Scruttonia (Rugosa, Cnidaria) From The Devonian Of Western Australia, Anthony J. Wright Jan 1991

Scruttonia (Rugosa, Cnidaria) From The Devonian Of Western Australia, Anthony J. Wright

Faculty of Science, Medicine and Health - Papers: part A

Phillipsastrea delicatula Hill. 1936. from probably the early Frasnian (early Late Devonian) of the Lennard Shelf, Western Australia. is assigned to the cosmopolitan rugose coral genus Scruttonia. Its occurrence there supports the previously reported cosmopolitan nature of Late Devonian rugose coral faunas and the faunal similarities between eastern and Western Australia in the Devonia.


A New Early Devonian Spinose Phacopid Trilobite From Limekilns, New South Wales: Morphology, Affinities, Taphonomy And Palaeoenvironment, Anthony J. Wright, W Haas Jan 1990

A New Early Devonian Spinose Phacopid Trilobite From Limekilns, New South Wales: Morphology, Affinities, Taphonomy And Palaeoenvironment, Anthony J. Wright, W Haas

Faculty of Science, Medicine and Health - Papers: part A

Paciphacops (Paciphacops) crawfordae n.sp. is a distinctive spinose phacopid trilobite of late Pragian (Early Devonian) age from the deepwater, dysaerobic Rosedale Shale, Limekilns district, New South Wales. It is characterised by short occipital, genal and intergenal spines on the cephalon, and short thoracic spines on the axial rings and pleurae. Various combinations of such spines are developed in P. (Paciphacops) serratus Foerste (Lochkovian, New South Wales; Ludlovian, Kazakhstan?) and P. (Paciphacops) claviger Haas (Siegenian, Nevada), but the three species cannot be shown to be related.


The Archaeology Of Social Complexity In South-East Queensland, Michael Morwood Jan 1987

The Archaeology Of Social Complexity In South-East Queensland, Michael Morwood

Faculty of Science, Medicine and Health - Papers: part A

The widespread alliance systems of Australian Aboriginal society had an economic and survival value in harsh environments, but in resource-rich areas such as South-east Queensland it is more a question of strategies for increasing regional carrying capacity. Recent archaeological results in the area, with evidence of increases in site numbers and artefact deposition rates and diversification of subsistence resources to include small-bodied species, show the development of new patterns of technology, economy and demography following major environmental changes in the post-Pleistocene period. Widespread changes in Australian prehistory around 4000 years ago may have been triggered in certain key areas such ...


A New Species Of The Brachiopod Notanoplia (Notanopliidae) From The Early Devonian Of New South Wales, Anthony J. Wright Jan 1981

A New Species Of The Brachiopod Notanoplia (Notanopliidae) From The Early Devonian Of New South Wales, Anthony J. Wright

Faculty of Science, Medicine and Health - Papers: part A

Notanoplia mitchelli sp. nov., a new notanopliid brachiopod, is described from Bowning, N.S.W., probably from the Lochkovian (Early Devonian) Elmside Formation. The distinctive genus is known only from Early and Middle Devonian rocks, and is known from Australia and Western Europe, and possibly from China.


Evaluation Of A New Zealand Tremadocian Trilobite, Anthony J. Wright Jan 1979

Evaluation Of A New Zealand Tremadocian Trilobite, Anthony J. Wright

Faculty of Science, Medicine and Health - Papers: part A

Dionide hectori Reed, 1926, is shown on the basis of new collections from the type area in New Zealand to be a Tremadocian ceratopygide close to Hysterolenus. The species was placed in Taihungshania by Kobayashi (1941). It was provisionally retained in the Taihungshaniidae by Lu (1975) who made hectori type species of a new genus Hectoria (non Hectoria Trechmann, 1918). Ruapyge nom.nov. is proposed here for the reception of hectori. The original length/width ratio is determined by Wellman's method, with little consistency in results. Data from the strain ellipses constructed by Wellman's method are then used ...


Microbial Water Stress, A D. Brown Jan 1976

Microbial Water Stress, A D. Brown

Faculty of Science, Medicine and Health - Papers: part A

A fellow of my acquaintance, on seeing a colleague drink undiluted water (55.5 molal), has been known to comment in disapproval that water at such a concentration should not be used for that purpose and that its main function is for putting around the outside of boats. He conceded that dilution with a little salt is acceptable for boats but for no other purpose. The proponent of this philosophy is not a biologist and it is unlikely that many biologists would accept his generalization without some qualification. Nevertheless, it is a point of view. Another point of view with ...
