This study will contribute to the understanding of seagrass communities worldwide and to the development of effective seagrass monitoring and management programs. Although relatively remote and untouched, the subantarctic and Antarctic have not escaped the impacts of contamination. 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. This data will feed into predictive models which look at how climatic change and changes to fire regimes may impact the species germination response and subsequent persistence. Phylogeny of Antarctic Mosses Awards:
Why then, do we observe so many examples in nature, including our own species, in which individuals routinely delay or completely forgo their own reproductive opportunities in order to join and remain within a group? However very little is known about how the temperatures needed to break dormancy vary between and within sites, and what possible causes of any variation may exist. My research includes spatial and temporal analysis of Phyllospora wrack distribution and its associated invertebrate fauna. Decades of occupation in these areas have left a legacy of wastes that may be impacting the local biota. Aquaculture is a growing industry that provides an alternative source of seafood to wild caught fisheries.
This decision is intriguing as, on the face of it, one might expect an individual to maximise its genetic contribution by breeding as soon as possible and as many times as possible for the duration of its life. Sensitivity of subantarctic marine invertebrates to metals under a changing climate. Phyllospora comosa, an intertidal brown alga, provides important habitat for a wide variety of marine species, including invertebrates.

Professor David Ayre Co-supervisor: Over 20 sponge species have been catalogued thus far. Accepted pending minor revisions Physical Yow in a Changing Climate. Marine Ecology Progress Series. One way to improve productivity and lessen resource wastage would be to measure plant health from a tgesis and over large areas, allowing farmers to selectively allocate resources to plants which need them.
Polar regions are predicted to experience some of the most pronounced climatic changes over the next century, with subsequent effects on biologically accessible water of particular concern.
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. Bryophyte species composition over moisture gradients in the Windmill Islands, East Antarctica: 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.
The biotic and abiotic factors driving this distribution were also investigated using statistical models and manipulative experiments. By studying the variation of dormancy-breaking temperature ttacking 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.
This project will investigate the ecological, social and life history factors at the root of this decision in a model group of coral-reef associated fishes. Integrating transient heterogeneity of non-photochemical quenching in shade-grown heterobaric leaves of avocado Persea americana L. Spatial co-registration of ultra-high resolution visible, multispectral and thermal images acquired with a micro-UAV over Antarctic moss beds.
Investigating competitive effects between co-flowering plant species and the role of the European honeybee Apis mellifera in driving these effects.
This project, in partnership with Fisheries Victoria Department of Environment and Primary Industriesaims to assess the viability of using off shore culture systems and various seaweed and formulated feeds to farm abalone.
However very little is known about how the temperatures needed to break dormancy vary between and within sites, and what possible causes of any variation may exist.

In addition, I fhesis using acoustic tracking to investigate issues surrounding the movement patterns of key soft sediment fishes. This study will contribute to the understanding of seagrass communities worldwide and to the development of effective seagrass monitoring and management programs.
Australian Journal of Botany. UOW has one of only three LIFT instruments in the world and in this project we will be examining how measurements with the LIFT instrument are affected by different crop species, leaf angle trackiing canopy structure as well as using LIFT to measure how plants cope with sun-flecks in low light environments.
