While the range of dinoflagellates and copepods tended to closely track the velocity of climate change (the rate of isotherm movement), the range of the diatoms moved much more slowly. Differences in range shifts were up to 900 km in a recent warming period, with average velocities of range movement between 7 km per decade northwards for taxa exhibiting niche plasticity and 99 km per decade for taxa exhibiting niche conservatism. The differing responses of taxa to global warming will cause spatial restructuring of the plankton ecosystem with likely consequences for grazing pressures on phytoplankton and hence for biogeochemical cycling, higher trophic levels and biodiversity.]]> Wed 11 Apr 2018 11:01:43 AEST ]]> Programmatic detection of spatial behaviour in an agent-based model. https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19623 Wed 11 Apr 2018 10:03:22 AEST ]]> Impact of marine heatwaves for sea turtle nest temperatures https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39071 Wed 04 May 2022 15:09:24 AEST ]]> Reconstructing past thermal conditions in beach microclimates https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44316 Tue 11 Oct 2022 16:19:25 AEDT ]]> A grid resource allocation mechanism for heterogeneous e-waste computers https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:9053 Sat 24 Mar 2018 08:41:06 AEDT ]]> Why decide: is a user's estimation of job completion time useful in grid resource allocation? https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8880 Sat 24 Mar 2018 08:40:43 AEDT ]]> Clustering obsolete computers to reduce e-waste https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:11192 Sat 24 Mar 2018 08:13:36 AEDT ]]> Resource allocation to conserve energy in distributed computing https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12313 Sat 24 Mar 2018 08:11:36 AEDT ]]> Reducing grid energy consumption through choice of resource allocation method https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:10061 Sat 24 Mar 2018 08:07:22 AEDT ]]> Reducing energy consumption in distributed computing through economic resource allocation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16617 Sat 24 Mar 2018 08:03:01 AEDT ]]> Implementing an agent based auction model on a cluster of re-used workstations https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5967 Sat 24 Mar 2018 07:47:25 AEDT ]]> Modelling service levels in a call centre with an agent-based model https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5968 Sat 24 Mar 2018 07:47:25 AEDT ]]> Predicting self-reported illness for professional team-sport athletes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29722 2282 AU, weekly-TL >2786 AU and monotony >0.78 AU) to best predict when athletes are at increased risk of self-reported illness. In addition, a reduction in overall wellbeing (<7.25 AU) in the presence of increased internal-TL as previously stated, was highlighted as a contributor to self-reported illness occurrence.These results indicate that self-report data can be successfully utilized to provide a novel understanding of the interactions between competition-associated stressors experienced by professional team-sport athletes and their susceptibility to illness. This may assist coaching staff to more effectively monitor players during the season and to potentially implement preventative measures to reduce the likelihood of illnesses occurring.]]> Sat 24 Mar 2018 07:33:25 AEDT ]]> Phenological shuffling of major marine phytoplankton groups over the last six decades https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40442 n = 10 taxa) tended to show a large seasonal advancement, the timing of peak abundance for dinoflagellates as group advancing 39 days over these six decades. By contrast diatoms (n = 35) did not show any change as a group in their timing of peak abundance over the time series. Granger causality testing suggested a major driver of these phenological changes has been ocean warming in general but more specifically the rate of spring temperature rise as the most important factor. We also found differences in the timing of peak abundance of harmful algal bloom taxa, with some showing peak abundance earlier while others have moved later. Main conclusions: There has been a fundamental transformation of the classic seasonal progression from blooms of diatoms to dinoflagellates, which lies at the heart of temperate marine food chains, as the classic bimodal diatom and dinoflagellate seasonal peaks are eroded to a more continuous, single, longer-lasting phytoplankton peak. This phenological shuffling within and between major taxonomic groups is likely to have profound implications for the transfer of energy to higher trophic levels.]]> Fri 22 Jul 2022 14:37:23 AEST ]]>
