Water Relations

Determining plant water relations in a seasonally dry-tropical landscape in central Queensland, Australia: Implications for understanding koala (Phascolarctos cinereus) ecology.

Sampling is under way to understand plant water relations in a heterogeneous seasonally dry tropical landscape in central Queensland, Australia. Variables are being collected on a monthly basis in an effort to understand seasonal variations in water and plant water relations, as related further to koala ecology. Climate variables being monitored include monthly rainfall, temperature, and humidity.
Additionally, plant characteristics of defined sampling areas based on elevation and plant associations are being monitored and sampled, including: floristics, structure, leaf water content, leaf area index, foliage projective cover, and phenology. This portion of the project is part of a larger study aimed at determining the influence of intraannual timing on plant community structure and composition, plant water relations, and plant behaviours influencing koala ecology in a novel habitat in seasonally dry tropical ecosystem in central Queensland, Australia.
Information learned from this study will contribute further to a long term study aimed at identifying ecosystem factors influencing koala ecology and population distribution in dry tropical ecosystems of Queensland. This is part of an effort to understand both the ecosystem and animal ecology in order to project the potential impact of global climate change on the dry tropical systems as related to koala occurrence and ecology.
