Abstract Measurements of water vapour flux from semi‐arid perennial woodland (mallee) were made for 3 years using eddy covariance instrumentation. There have been no previous long‐term, detailed measures use in this ecosystem. Latent energy (LE) on a half hourly basis was the measure combined soil and plant evaporation, ‘evapotranspiration’ ( E LE ) site. Aggregation over site measured rain (1136 mm) estimated evaporation (794 suggests that 342 mm or 30% had moved into past root zone...
1 Exchange of carbon dioxide (CO2) from soils can contribute significantly to the global warming potential (GWP) agro-ecosystems. Due variations in soil type, climatic conditions and land management practices, exchange CO2 differ markedly different geographical locations. The food industry is developing footprints for their products necessitating integration with other emissions along chain. It may be advantageous grow certain crops locations minimize soil, this provide offset chain, such as...
Surface albedo is a fundamental radiative parameter as it controls the Earth’s energy budget and directly affects climate. Satellite observations have long been used to capture temporal spatial variations of surface because their continuous global coverage. However, space-based products are often affected by errors in atmospheric correction, multi-angular bi-directional reflectance distribution function (BRDF) modelling, well spectral conversions. To validate products, an situ tower...
Abstract. Semi-arid woodlands, which are characterised by patchy vegetation interspersed with bare, open areas, frequently exposed to wildfire. During summer, long dry periods occasionally interrupted rainfall events. It is well known that rewetting of soil induces a flush respiration. However, the magnitude may differ between patches and areas because different organic matter content, could be further modulated Soils were collected from under trees, shrubs or in unburnt burnt sandy mallee...
Prolonged drought and salinity on the Chowilla floodplain of Murray River have caused deterioration E. largiflorens F.Muell. A putative hybrid with gracilis F.Muell, green box, withstands saline conditions. We aimed to substantiate that box is a test for agreement between morphological physiological characters amplified fragment length polymorphisms (AFLP). Mature stands were measured leaf, trunk, floral, cotyledon, carbon nitrogen isotope discrimination, specific leaf area (SLA) AFLP. Green...
A putative hybrid between Eucalyptus largiflorens F.Muell. and gracilis F.Muell., called green box, has attracted attention for its ability to grow on the salt- drought-affected Chowilla floodplain of Murray River in South Australia. Relationships carbon isotope discrimination (Δ13C) ratio substomatal ambient CO2 (ci/ca) indicated that box was not as water use efficient E. largiflorens. Specific leaf area significantly lower compared with (38.38 36.96 versus 43.71 cm2 g–1). Leaf nitrogen...
Abstract. Estimation of the basal or heterotrophic soil respiration is crucial for determination whether an ecosystem emitting sequestering carbon. A severe bushfire in January 2014 at Calperum flux tower, operational since August 2010, provided variation and leaf area index as recovered. We propose a function y-intercept estimate respiration. calculated assimilation rate from eddy covariance data light response functions to calculate incorporating suppression daytime autotrophic Ecosystem...

Abstract A naturally occurring putative hybrid between Eucalyptus largiflorens F. Muell and gracilis called Green Box tolerates saline conditions of the River Murray floodplains better than E. largiflorens. Revegetation strategies utilizing seedlings have had limited success because only a few are majority throw backs to Therefore, purpose this study was identify traits characteristic AFLP markers associated with enabling selection at seedling stage. This done by non-linear canonical...
