Kiwi Forego Vision in the Guidance of Their Nocturnal Activities
It is proposed that the Kiwi visual system has undergone adaptive regressive evolution driven by the trade-off between the relatively low rate of gain of visual information that is possible at low light levels, and the metabolic costs of extracting that information. Expand
The Relationship of Oxygen Supply for Activity to Body Temperature in Four Species of Lizards
The relationship of aerobic scope and body temperature in reptiles has been reconsidered and all data are consistent with the hypothesis that maximum aerobic scope occurs near the PBT in non-varanid thermophilic lizards. Expand
Westland Petrels and the Hoki fishery: determining co-occurrence using satellite telemetry
There was considerable variation in the amount of time that Westland Petrels spent in the vicinity (i.e. within 5 km) of Hoki fishing vessels, and diet studies undertaken in conjunction with satellite tracking overestimated the importance of fisheries waste. Expand
Modeling the demography and population dynamics of a subtropical seabird, and the influence of environmental factors
Despite many threats operating throughout the breeding and foraging range of Westland Petrels, it appears that marine environmental change is a strongly influential factor for the species, with uncertainty in population growth due to predicted increases in sea-surface temperature in the future.

Breeding biology and breeding success of the blue penguin (Eudyptula minor) on the West Coast of New Zealand's South Island
The first detailed study of the timing and breeding success of an apparently declining population of blue penguins on the West Coast, South Island, New Zealand, suggests that road traffic may be a major contributing factor to the decline of the blue penguin population. Expand
Changes in oxygen consumption and heart-rate with activity and body temperature in the tuatara, Sphenodon punctatum.
The oxygen consumption and heart-rates of inactive Sphenodon at 30°C are 55 and 204 per cent, respectively, of predicted values for lizards of the same weight, and tuataras resemble cryophilic lizards. Expand
Seabird mortality induced by land-based artificial lights.
The most urgently needed actions to mitigate and understand light-induced mortality of seabirds are estimation of mortality and effects on populations; determination of threshold light levels and safe distances from light sources; documentation of the fate of rescued birds; improvement of rescue campaigns; and research on seabird-friendly lights to reduce attraction.

Population sizes of shearwaters (Puffinus spp.) breeding in New Zealand, with recommendations for monitoring
We reviewed population data for the nine taxa of shearwaters Puffinus spp. that nest in the New Zealand region. Data for about 350 current breeding colonies were found, and each taxon nested atExpand
Sexual Dimorphism in the Kea Nestor notabilis
The results demonstrate that Kea are sexually dimorphic, and Culmen length appears to be a useful means for distinguishing sexes in the field, and there was no evidence that sexual dimorphism increases with sexual maturity in this species. Expand
Differences in habitat selection between Chatham petrels (Pterodroma axillaris) and broad-billed prions (Pachyptila vittata) : implications for management of burrow competition
Habitat characteristics surrounding both Chatham petrel and broad-billed prion burrows were quantified and selection ratios compared, and it is recommended that selection values be used when deciding on the best location to establish a second ChathamPetrel colony. Expand
