Supervisor: Dr Oliver Knox Phone: 02 6773 2946; email: oknox@une.edu.au

I have a broad interest in cropping systems and their biology, which currently has a focus on cotton based production systems.


Supervisor: Dr. Guy Roth Phone: 02 6792 5340 ; email: guyroth@roth.net.au

Guy is based out at Narrabri where he runs his own private research and development business focussing on crop agronomy and environmental management for farms.  He is a former Rural Science student.  It is likely a scholarship could be provided for the projects. An Armidale co supervisor would be arranged.


Supervisor: CSIRO-NSW DPI Supervisor: Professor Paul Greenwood (CSIRO Livestock Systems and NSW DPI Livestock Systems)

UNE Supervisor: Dr Fran Crowley, Lecturer in Livestock Production

A project looking at soil compaction and crop yield responses would be possible. It would look at fields picked with the new John Deere Round Bale Cotton Pickers. The field work would be in April/May somewhere where cotton is grown.  The main purpose would be interacting with a couple of growers, measuring the soil and plant response.

Measurement of Pasture Intake by Grazing Cattle using the “eGrazor”

We are developing wireless sensor network methods that measure pasture intake by individual grazing cattle. This Honours project will use our pasture intake and other grazing and laboratory facilities and benchmark systems to generate pasture intake data to enable refinement of our sensor algorithms that estimate pasture intake by cattle. The project will provide the student with experience in the use of “eGrazor” sensor devices that classify behaviours and estimate pasture intake, in the calibration and use of devices for indirect assessment of pasture biomass, and in the use of chemical marker methods to estimate pasture intake, as part of a designed experiment. The Honours student will work with our highly experienced Feed Efficiency team based at the CSIRO FD McMaster Pastoral Research Laboratory, Chiswick in Armidale.


Supervisor: Prof Brian Sindel

Phone: 02 6773 3747; email: bsindel@une.edu.au

Supervisor: A/Prof Paul Kristiansen

Phone: 02 6773 2962; email: paul.kristiansen@une.edu.au

Contact me if you are interested in exploring horticulture (e.g. vegetable production, tree crop physiology), biofertilisers from ‘wastes’, new crop development (e.g. medicinal plants), and complementary farming systems (e.g. organics, inter-cropping). I am also working on projects associated with invasive weeds, soil fertility management, supply chain development and farmer behaviour. In addition to the project listed below, I’m happy to develop projects in areas of interest to students.

Weed management in vegetable production systems – Paul Kristiansen, Brian Sindel

We have a range of potential projects related to weed management in vegetable production systems. Topics include:

  • weed seed bank assessment and management
  • impact of strategic tillage, seasonal rotations, cover crops, cultural practices (planting, fertilising, irrigating) and hand weeding on weed infestations in vegetable production
  • economic evaluation of specific weed control methods as well as IWM generally.

Animal Science

Contact Sam Clark (sam.clark@une.edu.au) or supervisor

There are a variety of Honours projects available in Animal Science. This is just a sample of the projects that have been put forward by potential supervisors. If you have other interests please contact sam.clark@une.edu.au or the potential supervisor to discuss your ideas.

Animal welfare and behaviour

Supervisors: Dr Dana Campbell and Dr Caroline Lee (CSIRO)

Email: Caroline.Lee@csiro.au

Early interventions and range use of free-range laying hens

Free-range egg productions systems are increasing within Australia in response to consumer demands for more ‘natural housing’. But scientific research is needed to determine how these systems affect hen behaviour and welfare. Modifying the environment that chicks are raised in is a possible method of influencing their adaptation to the free-range system as adults. This Honours Project will use video recordings and RFID technology to look at variation in daily range visitation frequency, duration on the range and behaviours exhibited on the range by adult laying hens during peak egg production. Comparisons will be made between hens that were exposed to a variable environment during development (novel objects, sounds, light patterns) versus hens that were reared in standard housing conditions.

Other projects in animal welfare and behaviour may be available, please contact the supervisors listed above or Dr Amanda Doughty adought3@une.edu.au

AGBU projects

The Animal Genetics and Breeding Unit (AGBU) is a joint venture of NSW Department of Primary Industries and University of New England. AGBU is a team of approximately 20 researchers and professional staff who develop genetic evaluation systems for livestock industries. Researchers at AGBU work closely with industry and students can tackle a range of research topics relevant for commercial breeding programs. All projects would use data from current research or industry breeding programs from sheep, beef cattle pigs and trees.


PARG – Precision Agriculture

1)      Detection of calving and pre-calving behaviour in cows using GPS tracking technologies and real-time Taggle tracking Eartags (Collaborative Project with NSW DPI);

2)      Investigation of water and fertiliser use efficiency in crops using soil EM38 sensors and plant vigour sensors (Collaborative project with CRC Spatial Information);

3)      Examining the potential for Site Specific Management in Hop production (based in Victoria or Tasmania in collaboration with Hop Products Australia – potential scholarship available from the Bath-Hass Group);

4)      Precision fertiliser management in grazing systems (Collaborative project with Sundown Pastoral); and

5)      Calibration of active optical sensors for pasture biomass assessment, both quantity and quality


Botany

Contact Professor Jeremy Bruhl (jbruhl@une.edu.au) or supervisor

I am happy to consider supervising students interested in undertaking Honours in Botany/Plant Systematics/Plant Taxonomy. I am also happy to consider co-supervise projects that have a botanical component where my skills complement the main supervisor.

With my hat on as director of the N.C.W. Beadle Herbarium I am keen to facilitate all students, regardless of who the supervisors are, in their use of the Herbarium (NE), the Herbarium database (NEdb), and our kit for collecting and preparing plant specimen vouchers.

I have strong expertise in Asteraceae (daisies), Cyperaceae (sedges), Phyllanthaceae and suitable experience in a wide range of other plant families.

I can suggest projects in Acacia, Asteraceae, Cyperaceae, Eucalyptus, Comesperma, Phyllanthaceae, and others. Most of the projects involve one or more of the following:

Resolving taxonomic questions about species: what are the species (often resulting in the student being able to co-author the description of new species).

Resolving phylogenetic relationships: what are the evolutionary relationships of a group of species

Understanding character homology: what is the variation in particular characters across a study group. This could be combined with production of an interactive identification dataset.

Depending on the topic and approaches I may suggest involving a co-supervisor from another institution (e.g. Australian National Herbarium or the National Herbarium of NSW) or from within UNE (e.g. Dr Rose Andrew, Prof. Caroline Gross) as best fits the needs of the project.


Dr Nigel Warwick: nwarwick@une.edu.au. Plant stress physiology, plant function and ecological anatomy

I have a number of projects with a focus on plant stress physiology, plant function and ecological anatomy. These include but are not limited to:

  • Developmental physiology and genetics of durum wheat looking at effects of dwarfing genes on yield and floret fertility and reserve carbohydrate distribution
  • Effect of canopy temperature depression on yield in durum wheats
  • Role of inhibitors in glumes of progenitors of the A and B genomes of durum wheat and their effect on pre-harvest sprouting
  • Wood and bark anatomy and water transport and carbon dynamics in Acacia spp. and Callitris glaucophylla
  • Phyllode and leaf functional anatomy of Acacia spp. and Callitris glaucophylla in relation to climate

Supervisor: Romina Rader (rrader@une.edu.au)

Pollinator biodiversity in orchards

Worldwide, insect pollinators have been shown to be significant contributors to biodiversity and the provision of ecosystem services within production systems.  Crop plants provide people with food, fibre and commodities but they also provide foraging and nesting resources for a diverse range of wild pollinators.  In turn, wild pollinators support farm productivity by providing pollination services to produce fruits and seeds, especially when honeybee numbers are insufficient or unfavourable weather conditions prevent honeybees from flying. While several studies abroad have demonstrated that wild pollinators are integral to optimal fruit set and stable crop pollination services, few studies have been conducted in Australia within horticultural land uses (ie avocado, mango, macadamia, blueberry etc). We will investigate the role of wild pollinator diversity in enhancing the stability and productivity of crops grown in New South Wales.

Skills: The student will gain knowledge in field experiment design and implementation, statistical analysis and measuring fruit quality characteristics of relevance to global markets.


Environmental Science

Pollution Science

Supervisor: Dr Susan Wilson. swilso24@une.edu.au; Dr Matt Tighe. mtighe2@une.edu.au

Many Australian Soils are affected by contamination resulting in lost productivity or causing real hazards to human health and the environment. In the New England area we have over 3000 contaminated derelict mine sites. Many agricultural areas are impacted by pesticides. Coal seam gas exploration, a hot topic regionally, is associated with its own contamination problems. Understanding the fate and behaviour of contaminants in the soil environment is important for recognizing adverse effects and also for deciding on appropriate management and remediation. Current research projects may be helped by external source funding. If a student has an interest within this area we can discuss specific project ideas. Alternatively, a number of possible project ideas are described below.

  • Biogeochemical cycling of Arsenic and Antimony
  • Rehabilitation strategies at mine sites: amendments to manage leaching, phytoremediation, plant based management strategies, risks associated with arsenic and antimony in soils.
  • Municipal waste composts and other amendments applied to soils – risks of metals and organic pollutants.
  • Pollutants in organic amendments used for soil fertility and rehabilitation – risks to crops and ecosystems
  • Fate and persistence of herbicides on the sub-antarctic Macquarie Island
  • Archaeological contamination and the timeline of bioavailability
  • Contaminant monitoring and analysis – using speciation analysis to assess risks
  • Bioavailability and risk – PAHs and other organic xenobiotics

Project 1. This project has $5000 external funding associated with it.

Establishing site specific contaminant thresholds for post operations and rehabilitation at Hillgrove gold/antimony Mine


Soil Carbon

Associate Professor Brian Wilson. Email: brian.wilson@uen.edu.au

“Soil carbon quantities and dynamics under changing climate and land-use”

There are potentially a wide range of projects available all linked to national soil carbon programs which can be discussed with Brian directly.


Soil Biology

Dr Oliver Knox. Email: oknox@une.edu.au

These projects may come with CRDC support

Axonchium, the soil nematode we know nothing about!

The student will get to know soil nematode recovery techniques and subsequent culturing methods. We have identified an Axonchium species, which is probably a new species, but this genera is characterised by a lack of visible mouth parts. There is debate in the literature as to what it eats elsewhere in the world, but with this nematode becoming more prevalent in cotton and grains cropping areas it would be useful to address this. So if you are interested in working with a potentially new species and addressing what this genera feeds on then this is for you.

Does how we recover soils alter the microbial community?

We routinely core in order to take soil samples, but often we have to use surfactants to aid in the core recovery. These surfactants apparently have limited impact on the Carbon we find in the recovered soils, but what possible impacts do they have on the soil microbiology? We are seeking a student who would address this through a series of soil exposure and respiration measurements using a number of techniques.

Oliver Knox and Katherine Polain – can provide some CRDC support from UNE1601


Plant Stress Biology

Associate Professor Priti Krishna

Phone: 02 6773 3075; Email: pkrishn2@une.edu.au

Brassinosteroids (BRs) are a new group of plant hormones that control important agronomic traits such as flowering time, plant architecture, seed yield and stress tolerance. Thus, BR-related genes offer unique possibilities for substantially increasing crop yields and resistance to environmental stresses, which are top agricultural priorities worldwide under growing concerns from climate change. BR is a hot topic of research, offering students an opportunity to make pioneering discoveries of BR-related genes, pathways and gene networks that converge on producing broad-spectrum stress tolerance and increase in yield potential.

We have identified a subset of new BR-responsive genes that can potentially benefit crop productivity. The phenotypes in response to salinity stress of the knockout mutant bp1, wild type Arabidopsis thaliana seedlings (WT), and overexpressing transgenic line (35S::BP1)of one such gene BP1 are shown in the Figure below. We are looking to functionally characterise some of these genes using a combination of genomic/molecular biology approaches.

Students can choose aspects of gene/protein characterization they would like to be involved in; the ultimate goal is to understand the mode of action of these genes and to assess if they can be valuable to crop improvement programs.

Soil Health and Land Management

Lisa Lobry de Bruyn llobryde@une.edu.au

In order for farmers to maintain or improve soil health through their management they need to access and use good quality, local soil information, including identification of soil types and their soil health status (here using available soil testing as a proxy).  Tracking of soil health status, at the local level, largely falls to farmers. Despite recurrent language, in policy and other documents, suggesting farmers’ monitoring of soil health is necessary to guide decision-making and land management practices, the reality of their practice, is relatively unknown. It appears that we have assumed what motivates farmers to soil test but have not asked them. This project would work with landholders undertaking soil testing workshops on soil testing and interpretation of their own soil test results, and examine what they do with the soil data they collect and how it influences their land management decisions.

Skills: analysing surveys, undertaking a qualitative analysis and follow-up interviews. Data is currently being collected, Human Research Ethics application already undertaken, but opportunities to collect more data in February and April/May of 2017.


Macquarie Island weeds projects

Poa annua and Stellaria media invasive weeds of sub-Antarctic Islands (e.g. Macquarie Island), impacting on native biodiversity. Given high conservation values, and threats from disturbance & climate change, the development of targeted control measures for invasive species is vital. These weeds and Cerastium fontanum may be included in research projects.

Germination ecology of Poa annua or Stellaria media in sub-Antarctic conditions

Little is known about the seed ecology and soil seed bank of P. annua and Stellaria media. This project will generate results that may be used to develop effective, low-impact control options for P. annua in the sub-Antarctic, and has broader implications for Antarctic conservation.

Control of Poa annua and/or Stellaria media in cold climates

The efficacy of herbicides against Poa annua and/or Stellaria media in cold conditions has received limited study in Australia. As a prolific weed in many parts of the world, a better understanding of the efficacy of different herbicides will assist in developing effective, low-impact management strategies to manage the weed. Other sub-Antarctic weeds and native plants may also be studied.

Behavioural Ecology Lab

Supervisor: Dr Paul McDonald

Potential projects fall into the below areas according to species, but happy to discuss specific project ideas students may have: paul.mcdonald@une.edu.au

Noisy Miners

Do Noisy Miners eavesdrop on other species? Many species give alarm calls that indicate danger, but do miners bother listening to others? More broadly, this will provide information on how animals see (or hear) to understand their surroundings, and the types of information that is salient to prey species.

Why are miner chicks so loud? Despite begging being a dangerous thing to do as it may attract predators to nests, miner chicks are incredibly loud. Why, and how, does colony structure and connectivity influence begging to overcome these risks?

Do miners avoid responding to a hopeless alarm caller? Animals have access to lots of information in their environment, but who to listen to? This project would examine whether birds pay more attention to a reliable signaller, and conversely ignore those with poor accuracy. This has implications for communication broadly and understanding sociality.

How does body condition influence social hierarchy? Understanding who does what in a social system is an important step in determining the factors that shape cooperative behaviour. One understudied facet is condition, ie how much fat reserves an individual has. This project will challenge birds of different condition in a series of experiments to better understand the trade-offs between risk, condition, and helping behaviour.

Some noisy miner projects are linked to Environmental Trust funding, collaborations with University of Queensland and Australian Museum, working on Local Land Services and Armidale-Dumaresq Council land.


Pigeons

Crested pigeon behaviour and habits: Perhaps one of our most common birds, yet we know very little about this species. This project will use camera traps and supplemental food to examine pigeon abundance and behaviour to better understand these birds and their movements.


Ducks

What would a wood duck do? Again, one of our most commonly seen ducks, yet we know little about these birds. Building on the results of a 6 month long GPS tracking study, this project looks to find out more about this species in the local area around Armidale, from its movements to breeding behaviour.

Pigeon and duck projects are both partially funded by a DPI grant.


All projects require a mix of lab/computer work and fieldwork. Start date (T1/2/3) is negotiable. Some are local in Armidale, whilst others will require travel within NSW. If interested, contact me for more information.
