Parviflora. Managed hives of Tetragonula carbonaria were placed in bushland at Lake Macquarie, New South Wales, Australia, in four known populations of Grevillea parviflora subsp. parviflora through the main flowering period of 12 September to 2 November 2014. Samples of honey and propolis were collected from the hives at the end of this period and analysed using palynology techniques for the presence of Grevillea parviflora subsp. parviflora pollen. Grevillea parviflora subsp. parviflora pollen was detected in all propolis samples from the four study sites but was not found in the honey samples. Field observations identified that honeybees were the dominant insect visitor to Grevillea parviflora subsp. parviflora at all sites. There were no sightings of Tetragonula carbonaria foraging on Grevillea parviflora subsp. parviflora inflorescences during field observations. This study also demonstrates the application of managed hives of the Australian stingless bees Tetragonula carbonaria for monitoring floral diversity where propolis samples can be used to indicate plant species richness (biodiversity) and the presence of specific species relevant to conservation within their foraging area.]]> Tue 20 Sep 2022 11:02:29 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53974 Staphylococcus aureus strains are a great contributor to both hospital acquired infections as well as community acquired infections. The objective of the present investigation was to compare potential differences in cytoplasmic amino acid levels between clinical and ATCC 29213 strains of S. aureus. The two strains were grown under ideal conditions to mid-exponential and stationary growth phases, after which they were harvested to analyze their amino acid profiles. Initially, the amino acid patterns of both strains were compared at the mid-exponential phase when grown in controlled conditions. At the mid-exponential phase, both strains shared common features in cytoplasmic amino acid levels, with glutamic acid, aspartic acid, proline, and alanine identified as key amino acids. However, the concentration profiles of seven amino acids exhibited major variances between the strains, even though the total cytoplasmic levels of amino acids did not alter significantly. At the stationary phase, the magnitudes of the amino acids abundant in the mid-exponential phase were altered. Aspartic acid became the most abundant amino acid in both strains accounting for 44% and 59% of the total amino acids in the clinical and ATCC 29213 strains, respectively. Lysine was the second most abundant amino acid in both strains, accounting for 16% of the total cytoplasmic amino acids, followed by glutamic acid, the concentration of which was significantly higher in the clinical strain than in the ATCC 29213 strain. Interestingly, histidine was clearly present in the clinical strain but was virtually lacking in the ATCC 29213 strain. This study reveals the dynamic diversity of amino acid levels among strains, which is an essential step toward illustrating the variability in S. aureus cytoplasmic amino acid profiles and could be significant in explaining variances among strains of S. aureus.]]> Thu 25 Jan 2024 09:42:56 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49983 Thu 22 Jun 2023 12:13:41 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51487 Thu 07 Sep 2023 10:52:49 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32111 Grevillea parviflora to the threatened species of microbats that have taken up residence in the tunnels.
