By increasing yields, using environmentally sensitive methods, the efficiency and production potential of culture systems increases. Large temporal and spatial gaps in meteorological data limit our ability to understand past and present trends, and so to forecast the future; making the development of innovative climate proxies a high priority. Phylogeny of Antarctic Mosses Awards: Associate Professor Todd Minchinton Email: One way to improve productivity and lessen resource wastage would be to measure plant health from a distance and over large areas, allowing farmers to selectively allocate resources to plants which need them. Mediterranean seagrass ecosystems are also being investigated to widen the scope of my research.
Spatial co-registration of ultra-high resolution visible, multispectral and thermal images acquired with a micro-UAV over Antarctic moss beds. This study will contribute to our understanding of seed ecology in fire-prone ecosystems and therefore improve our ability to predict and manage potential risks to species in fire-prone vegetation, under increasing anthropogenic management and future climatic changes. Posidonia australis is a threatened seagrass species with endangered populations in the Sydney region, NSW. Low-impact monitoring of dynamic vegetation communities in East Antarctica Publications: I use Stereo Baited Remote Underwater Video BRUVs to identify and compare fish communities found on temperate soft sediments, including in NSW marine park sanctuary zones no-take zones , habitat protection zones recreational fishing allowed and areas outside of the marine park that are targeted by both recreational fishers and commercial fishing vessels. Variation of physical dormancy and its ecological role in unpredictable environments Publications:
Phyllospora comosa, an intertidal brown alga, provides important habitat for a wide variety of marine species, including invertebrates. One way to improve productivity and lessen resource wastage would be to measure travking health from a distance and over large areas, allowing farmers to selectively allocate resources to plants which need them.
Low-impact monitoring of dynamic vegetation communities in East Antarctica. An understanding of these complex interactions is essential to developing effective management practises for invasive species.
I am also building a Bayesian network to model the factors that influence the abundance and longevity of Phyllospora wrack in a future ocean.

Genetic tests of the isolation of rare coastal dwarf populations of Banksia spinulosa. This involves species identification using microscopy, vegetation cover classification using object-based image analysis software, modelling of environmental parameters across sites in Antarctica and long-term climate analyses.
This study will contribute to our understanding of seed ecology in fire-prone ecosystems and therefore improve our ability to predict and manage potential risks to species in fire-prone vegetation, under increasing anthropogenic management and future climatic changes.

Whilst CBPs are having success with rearing of animals, there are induced changes in the morphology, physiology and behaviour of animals resulting in low survivorship and poor success in reintroductions.
Thesis Submission and Graduation
In fire prone environments, many plant species are killed by the passage of fire and recruitment from the seed bank post fire is critical to ensure populations are sustained.
By studying the variation of dormancy-breaking temperature thresholds within populations of fire-following physically dormant species, as well as among years of seed production and seed age in the seed bank, my project will investigate physical dormancy variation and subsequently the mechanistic processes potentially controlling seed bank dynamics.
