Influence of foliar traits on forage selection by introduced red deer in New Zealand

Understanding diet selection is to relate diet choices to the foliar and structural traits of forage species. Using data on diet selection by red deer  in Fiordland National Park, New Zealand, we determined the extent to which interspecific differences in the palatability of 46 plant species could be explained by 11 chemical and structural characteristics of plant foliage.

Landscape-level vegetation recovery from herbivory: progress after four decades of invasive red deer control

Report long-term vegetation changes in permanent plots located in forest, shrubland and grassland communities across a mountain range in southern New Zealand. We test whether 92% reduction in the population of invasive non-indigenous red deer, Cervus elaphus, since 1964 has led to the recovery of deer-preferred species.

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.


Disturbances prevent stem size-density distributions in natural forests from following scaling relationships

Enquist and Niklas propose that trees in natural forests have invariant size-density distributions (SDDs) that scale as a -2 power of stem diameter, although early studies described such distributions using negative exponential functions. Using New Zealand and ‘global’ data sets, we demonstrate that neither type of function accurately describes the SDD over the entire diameter range.
