Project 2.5ii.2 - Climate change: Scaling from trees to ecosystems

Project Leader and Host Organisation

Dr Michael Liddell, James Cook University

Project Description and Objectives

For detailed descriptions of the outputs for this project for Year 4 (2009/2010) of the MTSRF Research Programme, see the Annual Research Plan.

Most of the research discussed in Program 5ii is at the landscape level with a range of sites being used to provide data for the modelling work. Project 2.5ii.2 will look in much more detail at two sites in particular (tropical lowland rainforest) and determine how plants and invertebrates respond physiologically and phenologically (e.g. fruiting, flowering) to natural climate variability, and how trees and forests as a whole respond in terms of carbon and water use. This information will be used to indicate the sensitivity of ecosystems of this type to climate change. This research will be carried out at the Australian Canopy Crane research facility and the SkyRail rainforest cableway and takes advantage of over $50 million in infrastructure and ten years' worth of existing data sets.

Key Objectives:

  1. To improve our understanding of the factors influencing the variability in carbon and water fluxes from the rainforest through a long-term study in parallel with microclimate measurements;

  2. To monitor the differential effect of climate change on productivity of different floristic elements of a taxonomically diverse rainforest canopy – essential baseline data for predictive and scaling models of ecosystem productivity;

  3. To determine the fluxes of carbon and water below ground, and the factors controlling these fluxes, including the influence of climate;

  4. To describe flowering and fruiting phenology in lowland rainforest and determine correlations with fluctuations in climatology; and

  5. To understand how invertebrate resource use fluctuates in relation to seasonal local climatic variables and link this to ecosystem productivity and plant phenology.

Major Project Outputs

The Annual Research Plans, or ARPs, outline the specific tasks, products, budgets and staff for each research project within each of the Research Themes and Programs of the MTSRF.  The ARPs also outline the key deliverables, or 'project milestones' (e.g. major reports, journal articles, communications products) to be achieved.

An ARP is developed for each operating year of the MTSRF (2006-2010).

Details of this and previous years' outputs from this project are included in each of the Annual Research Plans
