About

Alexander Cheesman completed his B.A. in Plant Sciences from Cambridge University (Pembroke College) in 2004 before taking a job as a field assistant on Barro Colorado Island, a research site of the Smithsonian Tropical Research Institute (STRI) in Panama. It was here that he developed an attachment to tropical systems which continues to today. In 2010 he completed a PhD in Soil and Water Science at the University of Florida, USA. Much of the field work for which was carried out in the remote wetlands of Panama with his supervisor, Dr Benjamin Turner. This led to a 2 year post-doctoral research fellowship at STRI with Dr Klaus Winter, a position funded jointly by the Smithsonian Institute Global Earth Observatory (SIGEO) and Center for Tropical Forest Studies (CTFS), now called CTFS-ForestGEO, with the objective of researching the effects of increasing temperature upon tree physiology in the tropics.  From June 2013 he took up a post-doctoral research fellowship at James Cook University (JCU) working with Dr Lucas Cernusak.

Ozone impacts on tropical vegetation; implications for forest productivity (Trop-Oz)

Indicative Funding
$150,292 (administered by University of Exeter)
Summary
Tropospheric ozone is the third most significant anthropogenic greenhouse gas and has been shown to reduce global plant productivity though oxidative stress. Although tropical forests have been highlighted as being potentially being vulnerable to this ozone damage, few studies have looked at role of ozone in these regions. This project will provide comprehensive measurements of the effects of ozone on plant physiology in tropical forests and use this new knowledge to parameterise global land-surface models.

Denitrification bioreactor trial in the Russell catchment of the Wet Tropics

Indicative Funding
$235,087 over 4 years (administered by Jaragun Pty Ltd)
Summary
This project will establish the effectiveness of denitrification bioreactors as an on-farm technology for removing dissolved inorganic nitrogen (DIN) in waters draining the Babinda Swamp Drainage Area. The region has been identified as a hotspot for DIN in the Great Barrier Reef catchment. This will be the first trial of denitrification bioreactors in the Wet Tropics. Denitrifying bioreactors route water through a high-carbon substrate under anaerobic conditions to encourage denitrification (the conversion of DIN to atmospheric N2). Two bioreactor configurations will be tested at two sites, and the potential for broader adoption will be assessed.

Australian Banana Growers Council: Denitrifying Bioreactors

Indicative Funding
$30,000 over 2 years (administered by Australian Banana Growers Council)
Summary
This project in conjunction with Australian Banana Growers Council seeks to establish the effectiveness of denitrification bioreactors as an on-farm technology to remove excess dissolved inorganic nitrogen (DIN) leaving farms in the Wet Tropics bioregion. The Russell River catchment has been identified as a hotspot for DIN loading to the Great Barrier Reef lagoon, and this work represents a novel approach to curb DIN loading to natural systems. Denitrifying bioreactors route drainage water through a high carbon substrate under anaerobic conditions to encourage denitrification (the conversion of DIN to atmospheric N2). This project will involved detailed site monitoring, installation and scientific evaluation of a bioreactor wall in the headwaters of the Russell River catchment.

Soil/landscape assessment and monitoring design for WTMIP `Catchment Repair and Treatment Systems Design Phase?

Indicative Funding
$38,467 (administered by Australian Wetlands Consulting Pty Ltd)
Summary
This project contributes to the Wet Tropics Major Integrated Project (WTMIP) in the Johnstone and Tully catchments. The `Catchment repair and treatment systems? activity area of the WTMIP aims to reduce nitrogen loads in runoff by installing and restoring wetlands and installing `denitrification bioreactors?. As part of the design phase of that activity we will assess soil and landscape features at the proposed sites and design the monitoring program to assess their effectiveness. This assessment and monitoring design will be done in collaboration with Australian Wetland Consulting and Alluvium, who will design the installations themselves.

Skyrail Rainforest Foundation - Research Funding

Oxygen isotope (?18O) composition of leaves and wood in rainforest plants grown under varying environmental conditions

Indicative Funding
$2,000
Summary
This project aims to identify environmental factors (such as varying altitudes, humidity, temperature, rainfall and carbon dioxide concentrations) that change the stable oxygen isotopic ratio within the wood and leaves of rainforest plants. This will be done through analysis of samples collected from wet tropics forests, and from grown plants in controlled greenhouses (with varying temperatures and CO2 levels). The results will help to explain how plants have responded to past environmental changes, and to infer how they will respond to future changes. This will assist in the development environmental management practices of the wet tropics bioregion.
