Methods: We conduct the first detailed mapping of habitat change in two of the largest forested wetlands in inland Australia, comparing wet and dry hydrological phases. Detailed photogrammetry, supported by extensive ground survey, allowed the interpretation of high resolution aerial photography to vegetation community level. Results: We found a consistent pattern of decline in non-woody vegetation, particularly amongst grasses utilising the C4 photosynthetic pathway. The C4 grasses Pseudoraphis spinescens and Paspalum distichum showed steep declines in the Barmah Millewa and Macquarie Marshes respectively, being replaced by River Red Gum E. camaldulensis. C3 sedges proved more resilient in both systems. Conclusions: Our results suggest that a pattern of tree expansion into non-woody wetland vegetation, characteristic of wetlands across the globe, is a major habitat structural change in the Australian floodplain wetlands studied. Projected hydrological impacts of climate change are likely to further restrict wetland grass foraging habitat in these semi-arid floodplain wetlands.]]> Tue 09 Aug 2022 14:59:18 AEST ]]> And we thought the Millennium Drought was bad: Assessing climate variability and change impacts on an Australian dryland wetland using an ecohydrologic emulator https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50662 Tue 01 Aug 2023 13:20:57 AEST ]]> Predicting floodplain inundation and vegetation dynamics in arid wetlands https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41238 Sat 30 Jul 2022 12:19:31 AEST ]]> Probing the structure-function relationship in pC₆TP:PCBM based organic photonic devices https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19398 b)pyrazine) (pC₆TP) and [6,6]-phenyl-C₆₁-butyric acid methylester (PCBM) have been prepared and studied as near infra-red (NIR) organic photonic devices. Photocurrent contributions from both components are observed and show a photoresponse down to approximately 1 eV. The performance of the devices as a function of annealing time is investigated. A model for the effect of structure on the NIR response of these devices is developed and highlights the ambipolar nature of pC₆TP as a charge transport material.]]> Sat 24 Mar 2018 07:52:04 AEDT ]]> Poly(2,3-dihexylthieno[3,4-b]pyrazine) via GRIM polymerization: simple preparation of a solution processable, low-band-gap conjugated polymer (letter) https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4860 Sat 24 Mar 2018 07:18:46 AEDT ]]> Linking hydraulic regime characteristics to vegetation status in the Macquarie Marshes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25097 Sat 24 Mar 2018 07:15:03 AEDT ]]> Resilience to drought of dryland wetlands threatened by climate change https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40534 Fri 22 Jul 2022 15:19:29 AEST ]]> Patch organization and resilience of dryland wetlands https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47221 Fri 16 Dec 2022 10:16:32 AEDT ]]> Australian forested wetlands under climate change: collapse or proliferation? https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43009 Fri 09 Sep 2022 14:46:25 AEST ]]>
