Resistance and resilience of New Zealand tree species to browsing

A prominent idea in the literature on plant–herbivore interactions is that fast-growing species have low resistance but high resilience to herbivory. Fast-growing species are selectively eaten by herbivores but recover quickly following damage. This is an analysis whether this resistance-resilience trade-off applies to New Zealand woody species, which evolved without exposure to mammalian herbivores.

Scaling of tree vascular transport systems along gradients of nutrient supply and altitude

Investigating whether trees growing at high altitude or on nutrient-depleted soils prioritise survival over minimising hydraulic resistance by narrowing xylem distally or of their vascular systems would be structured differently from those of trees growing under more benign conditions. Conduits were observed to narrow towards the periphery of vascular system within all members of allContinue reading “Scaling of tree vascular transport systems along gradients of nutrient supply and altitude”

Challenges to the generality of WBE theory

A critique of the use of WBE as a general tool with proposals that more complex models are necessary to accurately deal with the environmentally influential factors which effect natural forest communities. Coomes, D.A. 2006 PDF 

Long-Term Effects of Wild fire on Ecosystem Properties Across an Island Area Gradient

Boreal forest soils play an important role in the global carbon cycle by functioning as a large terrestrial carbon sink or source, and the alteration of fire regime through global change phenomena may influence this role. In this study a system of forested lake islands in the boreal zone of Sweden for which fire frequencyContinue reading “Long-Term Effects of Wild fire on Ecosystem Properties Across an Island Area Gradient”
