Decline in capture rate of stoats at high mouse densities in New Zealand <I>Nothofagus</I> forests
We present two statistical models documenting variations in density indices of stoats and of mice in New Zealand southern beech (Nothofagus spp.) forests. They confirm previous, simpler correlations showing that the summer capture rate of stoats increases with spring mouse density index up to about 20–25 mouse captures per 100 trap-nights (C/100TN). However, at much higher mouse densities (60–8...
متن کاملTemperature explains global variation in biomass among humid oldgrowth forests
Methods We developed a new approach to modelling the aboveground biomass of old-growth forest (AGBmax) based on the influences of temperature on gross primary productivity (GPP) and what we call total maintenance cost (TMC), which includes autotrophic respiration as well as leaf, stem and other plant construction required to maintain biomass. We parameterized the models with measured carbon flu...
متن کاملPopulation Studies of Isolated Nothofagus Fusca Stands in the Lower Otira Valley, South Island, New Zealand
Population size and structure of 52 isolated Nothofagus fusca stands were investigated in the lower Otira Valley, 3-6 km from a major population centre in the upper Taramakau catchment. The approximate age of N. fusca pioneer trees, estimated from partial increment cores and calculations based on diameter growth rates, indicated that nearly all isolated stands originated after 1600 AD, predomin...
متن کاملWind damage and response in New Zealand forests: a review
The literature on wind damage in New Zealand forests is reviewed to investigate how abiotic and biotic factors influence damage severity, damage type, and forest recovery. Winds that damage forests tend to result from extra-tropical depressions or from topographically enhanced westerly air flows. Severe wind damage can occur when wind speeds exceed c. 110 km/hr, although investigating the relat...
متن کاملNothofagus Truncata (hard Beech) in the Upper Taramakau Catchment, South Island, New Zealand
Scattered small stands of Nothofagus truncata occur in the upper Taramakau catchment, Arthur's Pass National Park, beyond the previously assumed range of the species in north Westland. Restricted to older soils on stable north to north-west slopes, the N. truncata stands are surrounded by N. fusca dominated forest and their upper altitudinal limits at 370-500 m border N. fusca-N. menziesii or N...
