Reliability of recharge rates estimated from groundwater age with a simplified analytical approach

Yanhui Dong, Yueqing Xie, Jun Zhang, Andrew J. Love, more

Hydrological Processes > 35 > 5 > n/a - n/a

Groundwater age is often used to estimate groundwater recharge through a simplified analytical approach. This estimated recharge is thought to be representative of the mean recharge between the point of entry and the sampling point. However, given the complexity in actual recharge, whether the mean recharge is reasonable is still unclear. This study examined the validity of the method to estimate...

Anna Mamaeva, Michael Taliansky, Anna Filippova, Andrew J. Love, more

New Phytologist > 227 > 5 > 1326 - 1334

In addition to photosynthesis, chloroplasts perform a variety of important cellular functions in the plant cell, which can, for example, regulate plant responses to abiotic and biotic stress conditions. Under stress, intensive chloroplast protein remodeling and degradation can occur, releasing large numbers of endogenous peptides. These protein‐derived peptides can be found intracellularly, but also...

A Reappraisal of the Hydrogeology of the Western Margin of the Great Artesian Basin: Chemistry, Isotopes and Groundwater Flow

Andrew J. Love, Paul Shand, Simon Fulton, Daniel Wohling, more

Procedia Earth and Planetary Science > 2017 > 17 > C > 428-431

The combination of hydrochemistry with other environmental tracers such as noble gases and uranium series dating of travertine deposits are providing new insights into the hydrogeology of the western margin of the GAB. Previous conceptual models of simple geology and geochemical evolution along flow paths have been re-examined. Our results show that a far more complex model is evolving involving complex...

Environmental Tracers in Groundwaters and Porewaters to Understand Groundwater Movement Through an Argillaceous Aquitard

Stacey C. Priestley, Andrew J. Love, Vincent Post, Paul Shand, more

Procedia Earth and Planetary Science > 2017 > 17 > C > 420-423

Inter-aquifer leakage through an aquitard can be an important component of groundwater flow and can occur by diffuse leakage or via preferential pathways along secondary permeability features. In order to properly characterize inter-aquifer leakage it is desirable to use both porewater from the aquitard in conjunction with a regional investigation of groundwater in the aquifers. The aim of this study...

Canopy enhanced chloride deposition in coastal South Australia and its application for the chloride mass balance method

Zijuan Deng, Stacey C. Priestley, Huade Guan, Andrew J. Love, more

Journal of Hydrology > 2013 > 497 > Complete > 62-70

Validity of the chloride mass balance (CMB) method relies on a good quantification of the total chloride input to the land surface. The traditional way to quantify the chloride input, using bulk precipitation measured in the open field is questionable to apply in forest catchments. Chloride deposition can be significantly enhanced by the tree canopies as indicated by previous throughfall studies....

Andrew J. Love, Sean N. Chapman, Slavica Matic, Emanuela Noris, more

Planta > 2012 > 236 > 4 > 1305-1313

Bovine papillomavirus type 1 (BPV-1) is an economically important virus that induces tumourigenic pathologies in horses and cows. Given that the BPV-1 L1 major coat protein can self-assemble into highly immunogenic higher-order structures, we transiently expressed it in Nicotiana benthamiana as a prelude to producing a candidate vaccine. It was found that plant codon optimization of L1 gave higher...
