Note. The scholarship has not been filled and is still available for 2016.

 


 

Honours 2016 ecology project: In-depth analysis of plant biodiversity centres in South Autralia

In addition to Honours projects already described here (see link under Prof. Andrew Lowe), a project is available on mapping conservation values, habitat condition and threats at high resolution over a set of identified plant biodiversity centres. The project involves working with rich spatial biodiversity data to help locate the most biodiverse habitats and their management needs, building on a recent assessment of plant biodiversity for the entire state. 


 

Honours/post-graduate research projects are available in biodiversity mapping, community ecology and functional ecology, co-supervised by senior academic staff.

Data analysis focused projects include biogeography and ecosystem modelling, mostly at regional to continental scales, examining ecosystem properties and how they are constrained.

Field-based and empirical projects include measuring variation in plant functional traits and their response to environmental change, comparative ecophysiology, and functional measures of ecosystem condition in remnant and restored environments.

Research Interests

Influence of environmental change on ecosystem properties and biodiversity assets

My research within Prof. Andrew Lowe's group and the Terrestrial Ecosystem Research Network (TERN: AusPlots/ATN) involves two main themes:

 

1) Ecological analysis of ecological communities along large-scale monitoring transects, particularly the TREND transect. The main focus is patterns of ecosystem composition and functional responses to changes in climate through space and time. This work aims to better understand how ecosystems in Australia respond to environmental change and apply this information to practical interventions.

2) Continental scale analysis of the distribution of plant biodiversity at ecosystem level. The aim is to map diversity according to various metrics (e.g. species richness, beta diversity, endemism, phylgenetic diversity) and determine how these are constrained by environmental gradients / heterogeneity and interact with land-use change and climate sensitivity. Outcomes are improved ecological understanding of biodiversity assets but also practical identification of conservation hotspots. On a practical level, this project involves the development of new biodiversity mapping functionality.

 

 

Taxonomy of Australian Lamiaceae

On-going research involves taxonomic revision of the genera Hemigenia and Microcorys (classification and species-level) and investigation of the evolution of stamen morphology and pollination systems (with Prof. Dr. Regine Claßen-Bockhoff's group).

 

Ecological and evolutionary analysis using the R language and statistical environment

I post some R code I have found useful for research in ecology and evolution here and some stand alone functions here.
