Flowering Records of Some Subalpine Trees and Shrubs at Arthur's Pass, New Zealand
The flowering periodicity and intensity of some subalpine trees and shrubs at Pegleg Flat, Arthur's Pass National Park, was recorded from 1981/82 to 1984/85. Moderate to heavy flowering of most species in 1981/82 was followed by two years of little or no flowering in 1982/83 and 1983/84; almost all species observed flowered heavily in 1984/85. No clear correlation was found between flowering in...
متن کاملDifferential responses of vertebrate and invertebrate herbivores to traits of New Zealand subalpine shrubs.
Plant traits are influenced by herbivore diet selection, but little is known about how traits are affected by different types of herbivores. We related eight traits of 27 subalpine shrub species in South Island, New Zealand, to damage of these shrubs by introduced red deer (Cervus elaphus) and native invertebrate herbivores using phylogenetically explicit modeling. Deer preferentially consumed ...
متن کاملDivaricating shrubs in Patagonia and New Zealand
There are at least three hypotheses to account for the abundance of divaricating shrubs in New Zealand: 1) Ratites in the form of 11 species of moa, led to divarication for browse protection (Greenwood and Atkinson, 1977); 2) Divarication evolved as a microclimatic shield (McGlone and Webb, 1981); 3) Divarication evolved to aid leaves in light harvesting (Kelly, 1994). In Patagonia before human...
متن کاملSakai and Wardle: Freezing Resistance of New Zealand Trees and Shrubs
Forty-two native woody species were selected to represent the range of temperature-related ecological gradients in New Zealand. Twigs collected in July (mid-winter) were sent by air to Sapporo, Japan, where they were artificially hardened and then tested for freezing resistance. Although only one plant of each species was sampled from each site in anyone year, results were consistent from year ...
متن کاملBiosecurity Implications of Exotic Beetles Attacking Trees and Shrubs in New Zealand
A survey of exotic beetles that attack trees or shrubs in New Zealand found 51 species of mainly Australian (58%) and European (25%) origin. In addition, three biological control agents have been released against woody adventive plant pests. The host range of most species is restricted to exotic crop and ornamental plants in New Zealand. Nine polyphagous borers sometimes attack dead wood of ind...
