‘Spatial distribution of the arboreal termite Microcerotermes turneri (Infraorder: Isoptera) in a eucalypt forest’
Termites are important members of terrestrial ecosystems given their role in nutrient cycling and soil formation, but there is surprisingly little information about some groups, particularly arboreal termites. Matthew’s study examined the spatial distribution of the arboreal termite across a number of spatial scales to assess whether nests are distributed at random across the forest, and to identify ideal microhabitats. Data collection took place at SERF, surveying 15.6 hectares of eucalypt forest.
From analysing marked GPS coordinates taken during systematic transect surveys, termites were found to have a slightly aggregated distribution, implying the colonies were not in competition with one another and may be part of the same budding supercolony. Comparing the frequencies of host tree species with representative forest samples revealed that 50 per cent of nests were found in Eucalyptus crebra trees, which was disproportionate to their small overall frequencies in the forest (5 per cent). Statistical tests indicated that the bark type and size of trees were the driving factors for host species “selection”. Nests were placed non-randomly on the tree in terms of both height and orientation, likely to maximise sun exposure, though this was counteracted by nest placement increasing the risk of destruction by nesting kingfishers and goannas.
Matthew’s ecological study of arboreal termites conducted at SERF provided important baseline information about an arboreal termite species and serves as an excellent foundation for more detailed studies of these important members of forest ecosystems. This information could prove useful in future rehabilitation efforts given the importance to nutrient cycling in forest ecosystems.

'The influence of vertical microphone placement on acoustic bird species richness estimates: developing a methodology for soundscape recordings'
During a Vacation Research Experience Scholarship field project in December 2012, Isabelle studied how the properties of birdsong and the positioning of automated birdsong recorders might influence species detectability made a useful contribution to environmental monitoring programs at SERF.
The study compared acoustic recordings made at upper canopy and ground height in open forest to determine whether bird species detection differed according to sensor height. The study tested whether differences in bird call frequency, call loudness, size, social behaviour and habitat preference influenced detectability. Her findings indicated that both louder and larger species were most likely to be missed by sensors at ground level.

Ant functional groups as bio-indicators of anthropogenic disturbance: Issues with interpreting predictability at the local scale
In Australia, ants are used as bio-indicators of habitat disturbance and stress within the ecosystem. During a short research project at SERF, Jaye studied the behaviour of ants involving assessing functional ant groups within three habitats of different levels of disturbance - forest, edge and pasture. The study found no significant difference between the ant communities at each site. This result could have implications for environmental impact assessments for mining companies, early warning systems for habitat degradation and general conservation strategies.

Effective control or pathway to invasion? Recruitment of native and Lantana camara L. seedlings after a low intensity burn
During his third year as an undergraduate student, David undertook a short research project to examine the recruitment of native and lantana seedlings after a low-intensity burn to provide information about how fire might impact on lantana and native species, and how fire might best be used as a management tool. This study benefits SERF's understanding of the ecology of its native plants, and the long-term management of problem weeds. Basing weed management on sound scientific knowledge allows more sustainable management outcomes for native plants and animals.

Jason Wimmer, QUT PhD student
Refining acoustic sensing techniques to improve their capability to monitor and study the impact of climate change and loss of habitat on native Australian fauna
Jason has a computing background, and is currently completing a PhD at QUT focusing on environmental acoustic sensing. His research is cross-disciplinary involving both IT and ecological research, as he is passionate about the environment and committed to making a significant contribution to sustainability.
Jason is involved in a number of ongoing projects, working with ecologists and biologists to refine acoustic sensing techniques to improve their capability to monitor and study the impact of climate change and loss of habitat on native Australian fauna.
At SERF, he undertook a research project to assess the effectiveness of various recording schedules and devices in detecting bird species, and comparing these results with manual species survey methods. This project involves deploying 3G-based sensor devices and standalone recording devices throughout the Samford facility, and assisting in conducting manual bird species surveys.
James Tilbury, Bachelor of Civil Engineering (Economics Minor)
Viability of collecting organic waste from households and converting it into compost and energy
For his undergraduate thesis, James researched the viability of collecting organic waste from households and converting it into compost and energy for farmers. The study revealed that there is a market for the compost and that it was economically feasible to collect the organic waste, however, the benefits of using compost from organic waste needed to be quantified to entice farmers to change their practices. In addition, James designed an eco-village for the SERF property involving site analysis, site investigation and planning for sustainable development.
During his time at QUT, James founded the QUT Chapter of Engineers Without Borders which ran a number of aid projects and sustainability initiatives such as:
- Deans Scholar for the Developing World – This program gives exceptional biomedical students from QUT the opportunity to spend time in southern India contributing to the design of medical technologies uniquely suited to this environment.
- Medical Aid Missions for Communities in Need – A project that aims set up a health centre by collecting redundant medical equipment from hospitals around Queensland, maintaining, repairing and distributing it along with spare parts, knowledge and training programs to communities who desperately need these facilities.
- The Bentinck Island project – A project involving QUT students building amenities blocks using recycled materials for Indigenous communities across the Gulf of Carpentaria.
- PC Program – Donating refurbished computers to refugees.
- School Outreach Program – Teaching students about sustainable development through hands-on workshops in schools.
James was also involved as a student representative in the Vice Chancellor's Sustainability Working Party. This group actively promotes, implements and develops environmentally sustainable practices within QUT and across the broader university community as well as promoting a culture of awareness of environmental sustainability issues within the university.

Facilitating an independent rainwater supply system for SERF
Capitalising on his trade background with 12 years' experience as a plumber, drainer and gasfitter, Matthew was able to gain a greater understanding of urban development and buildings.
Matthew designed an independent rainwater supply system for SERF as the property is not connected to town water. He achieved this by calculating the annual rainfall which could be harvested against the potential consumption of the building's facilities. Matthew replaced the existing lead flashings on the roof to provide a potable supply of rainwater without potential contamination, retrofitted the Barracks with water conservation fixtures and installed a suitable size water tank to collect the rainwater from the roof to service the building.
