Preliminary Investigations Of Pigment Responses To Phylloxera Infestation, A L. Blanchfield, K S. Powell, Sharon A. Robinson
Preliminary Investigations Of Pigment Responses To Phylloxera Infestation, A L. Blanchfield, K S. Powell, Sharon A. Robinson

Early detection of grape phylloxera (Daktulosphaira vitifoliae) infestation is vital for the implementation of post-outbreak quarantine in Australia. Remote sensing systems exploit changes in leaf pigment content associated with plant stress and offer a real possibility of a phylloxera-specific detection system. Pre-visual, symptomatic changes in the pigment content of phylloxera-infested grapevine leaves were investigated using high performance liquid chromatography (HPLC) as a potential aid to improve current phylloxera detection methods. A glasshouse trial was established to characterize the response of two grapevine varieties, Vitis vinifera ‘Cabernet Sauvignon’ and ‘Shiraz’, to phylloxera infestation, in a controlled environment. Field trials were conducted …
Radiocarbon Bomb Spike Reveals Biological Effects Of Antarctic Climate Change, Laurence J Clarke, Sharon A. Robinson, Quan Hua, David J. Ayre, David Fink
Radiocarbon Bomb Spike Reveals Biological Effects Of Antarctic Climate Change, Laurence J Clarke, Sharon A. Robinson, Quan Hua, David J. Ayre, David Fink

The Antarctic has experienced major changes in temperature, wind speed and stratospheric ozone levels during thelast 50 years. However, until recently continental Antarctica appeared to be little impacted by climate warming, thusbiological changes were predicted to be relatively slow. Detecting the biological effects of Antarctic climate changehas been hindered by the paucity of long-term data sets, particularly for organisms that have been exposed to thesechanges throughout their lives. We show that radiocarbon signals are preserved along shoots of the dominant Antarcticmoss flora and use these to determine accurate growth rates over a period of several decades, allowing us toexplore the …
Mechanisms Of Thermoregulation In Plants, Jennifer R. Watling, Nicole Grant, Rebecca E. Miller, Sharon A. Robinson
Mechanisms Of Thermoregulation In Plants, Jennifer R. Watling, Nicole Grant, Rebecca E. Miller, Sharon A. Robinson
Sharon Robinson
Endothermic heating of floral tissues and even thermoregulation is known to occur in a number of plant species across a wide taxonomic range. The mechanisms by which flowers heat, however, are only just beginning to be understood, and even less is known about how heating is regulated in response to changes in ambient temperature. We have recently demonstrated that the alternative pathway of respiration, in which the alternative oxidase (AOX) rather than cytochrome C (COX) acts as terminal electron acceptor, is responsible for heat generation in one thermoregulating species, the sacred lotus (Nelumbo nucifera). In the March issue of the …
Unmanned Aerial Vehicle (Uav) Remote Sensing For Hyperspatial Terrain Mapping Of Antarctic Moss Beds Based On Structure From Motion (Sfm) Point Clouds, A Lucieer, Sharon A. Robinson, D Turner
Unmanned Aerial Vehicle (Uav) Remote Sensing For Hyperspatial Terrain Mapping Of Antarctic Moss Beds Based On Structure From Motion (Sfm) Point Clouds, A Lucieer, Sharon A. Robinson, D Turner
Sharon Robinson
This study is the first to use an Unmanned Aerial Vehicle (UAV) for mapping moss beds in Antarctica. Mosses can be used as indicators for the regional effects of climate change. Mapping and monitoring their extent and health is therefore important. UAV aerial photography provides ultra-high resolution spatial data for this purpose. The aim of this study is to use Structure from Motion (SfM) techniques to generate a detailed 3D point cloud of the terrain from overlapping UAV photography.

The instrumental period began with the first voyages to the Southern Ocean during the Seventeenth and Eighteenth centuries when scientists such as Edmund Halley made observations of quantities such as geomagnetism. During the early voyages information was collected on the meteorological conditions across the Southern Ocean, ocean conditions, the sea ice extent and the terrestrial and marine biology. The continent itself was discovered in 1820, although the collection of data was sporadic through the remainder of the Nineteenth Century and it was not possible to venture into the inhospitable interior of Antarctica. At the start of the Twentieth Century stations …

Tertiary literacy instruction and assessment were introduced into two first year biology subjects as part of a collaboration between Biological Sciences and Learning Development staff at the University of Wollongong. In both subjects, the project focussed on scientific report assessment items based on aspects of the practical curriculum. The project involved production and use of a web site giving instruction in report writing and general guidance on scientific writing, marking schemes using explicit criteria including literacy based criteria, a peer marking tutorial, and marking and feedback using the schemes. The results from assessments in the second subject, which included the …
