Title: Examination of the photosynthetic behaviour (energy content, nutrient content, productivity and acclimation) of mosses and lichens throughout the summer season at Cape Hallett
Description:
Abstract:
A possible sign of climate change is likely to be improved production and growth in plants. The response of net photosynthetic rates were measured on the large areas of relatively uniform moss cover at Cape Hallet through the summer season to get an estimate of the energy content, nutrient content, productivity and acclimation of mosses and lichens. The results are the first step to a full description of energy flow in the ecosystem. The photosynthetic behaviour of two moss species Bryum subrotundifolium and Bryum pseudotriqueterum was completed. Net photosynthesis responses to plant water content and to light were first constructed in order to optimise the experimental conditions. Sets of net photosynthesis response to light were then constructed through the season at a constant temperature of 12 degrees. Mosses were given different additions of fertiliser (macro-nutrients, micronutrients or no treatment) and sampled the following season in order to detect any nutrient limitation. An additional set of trials was carried out on Prasiola (alga) and optimal temperatures for photosynthesis of B. subrotundifolium were determined.

Attribute_Accuracy_Report:
All data is held by the investigators. Please contact for more information. The plant collections (~30,000 mosses, liverwort and lichens collected by Professor Rod Seppelt from Antarctica and sub-Antarctic Islands) are housed in the Australian Antarctic Division herbarium. This herbarium is being formerly transferred to the Tasmanian Herbarium. As specimens are fully incorporated into the herbarium (ADT) the data is automatically sent to and held in the Antarctic Database at the Australian Antarctic Division Data Centre. The data is currently in two separate databases, one which searchable and the other is in the process of being moved over. For more information or access to samples, please contact: Professor Rod Seppelt Principal Research Scientist Australian Antarctic Division Channel highway Kingston 7050 Tasmania, Australia ph: +61 (03) 6232 3438 fax: +61 (03) 6232 3449 e-mail: rod.seppelt@aad.gov.au
