Title: | Changes in Allometric Attributes and Biomass of Forests and Woodlands across an Altitudinal and Rainfall Gradient: What Are the Implications of Increasing Seasonality due to Anthropogenic Climate Change? | Contributor(s): | Hunter, John T (author) | Publication Date: | 2015 | Open Access: | Yes | DOI: | 10.1155/2015/208975 | Handle Link: | https://hdl.handle.net/1959.11/17515 | Abstract: | Canonical correspondence analysis and linear regressions were used to relate height, diameter, and dispersion measurements of 36,380 stems from197 species recorded in 2,341 plots against both climatic and landscape variables.Above ground biomass increased in wetter and cooler locations that ameliorate the seasonal rainfall deficits. Taller and greater diameter trees with lower wood densities occur at higher altitudes. Differences between locations are based on a change in the composition of species rather than a change in the allometric properties within a species.The results support the hydraulic limitation and species packing hypotheses. These interrelationships may be affected by the interactions of fire frequency and drought which are a common feature of much of the study area.Under current climate change scenarios it is likely that there will be a reduction in above ground biomass, the number of stems per hectare, average height, average diameter, and basal area due to increasing seasonality of rainfall, temperatures, and the intensity and frequency of fires.The largest of trees are likely to be removed early due to their inability to cope with increased drought stress. The results suggest a marked reduction in carbon storage will occur across the study region in eastern Australia. | Publication Type: | Journal Article | Source of Publication: | International Journal of Ecology, p. 1-10 | Publisher: | Hindawi Publishing Corporation | Place of Publication: | United States of America | ISSN: | 1687-9716 1687-9708 |
