Decadal Vegetation Succession Along A Chronosequence Within Eucalyptus Obliqua Wet Forest, Southern Tasmania, Christine Dobbin
Decadal Vegetation Succession Along A Chronosequence Within Eucalyptus Obliqua Wet Forest, Southern Tasmania, Christine Dobbin
Independent Study Project (ISP) Collection
Southern Tasmania is home to fire dependent mixed forests, which, if not maintained, will eventually be replaced by the rainforest understorey. Wet eucalypt forest succession after disturbance events was investigated through floristic and vertical measurements of four north facing chronosequence plots with labels describing the age class of each, from regrowth to mature sites. This study was possible due to the establishment of permanent 50m x 50m plots in 2007 for longitudinal monitoring and subsequent illustration of forest dynamics following disturbance, including clearfell burns and wildfire. The contents of this report are the comparative analyses of the findings from the …
Toward An Improved Conceptual Understanding Of North American Tree Species Distributions, Paige E. Copenhaver-Parry
Toward An Improved Conceptual Understanding Of North American Tree Species Distributions, Paige E. Copenhaver-Parry
Faculty Publications - Department of Biological & Molecular Science
Species distributions have often been assumed to represent climatic limitations, yet recent evidence has challenged these assumptions and emphasized the potential importance of biotic interactions, dispersal limitation, and disturbance. Despite significant investigation into these factors, an integrated understanding of where and when they may be important is lacking. Here, we review evidence for the factors underlying the historical and contemporary distributions of North American tree species and argue that a cohesive conceptual framework must be informed by an understanding of species ecological and evolutionary history. We further demonstrate that available evidence offers little indication of a significant, independent influence of …
The Effects Of Disturbance And Species Specific Interactions On Diversity In An Agent Based Forest Simulation, Matthew E. Mills
The Effects Of Disturbance And Species Specific Interactions On Diversity In An Agent Based Forest Simulation, Matthew E. Mills
Theses and Dissertations
In ecology literature, there is much data which suggests that conspecific negative density dependence (CNDD) and abiotic disturbances increase biodiversity in forests. This thesis elucidates the notion that not only do these two forces increase diversity, but they may also interact with one another in order to achieve higher levels of biodiversity. Abiotic disturbances, like fires and hurricanes, can indirectly impact conspecific effects because when these forces remove individuals from the landscape, the role of the conspecific effects will change. The interaction of these two factors in biodiversity are explored in an agent based forest simulation through a resource surface. …
