Measuring diversity and abundance of invertebrates in Ahuriri, Coopers Knob and Orongomai Reserves in the Port Hills, Canterbury

Bowie Mike, H.; Vink Cor, J. (Lincoln University. Bio-Protection & Ecology Division, 2006-06)
The Port Hills Rangers (Greenspace Unit, Christchurch City Council) in conjunction with Environment Canterbury are ecologically restoring several reserves on the Port Hills of Canterbury. Vegetation, birds and invertebrates are being monitored to collect ...
Burrow occupancy and related behaviour of broad-billed prions Pachyptila vittata on South East (Rangatira) Island, Chatham Islands, New Zealand

Was, N. W.; Wilson Kerry Jayne (Lincoln University. Ecology and Entomology Group, 1998-07)
Burrow competition is occurring between broad-billed prions (Pachyptila vittata) and other small burrowing seabirds on South East (Rangatira) Island, Chatham Islands, New Zealand. This competition has a negative impact on the endangered Chatham petrel (Pt ...
Captive breeding of Wellington speargrass weevil

Emberson Rowan, M.; Scott, R. R.; Pawson Stephen, M. (Lincoln University. Soil, Plant & Ecological Sciences Division, 2004-06)
This project was initiated in May 1999 with the aim of determining optimum rearing conditions to breed Lyperobius huttoni in captivity. The programme has been relatively unsuccessful with only a single individual reared in captivity during 2001. However, ...
Induced defences in kawakawa (Macropiper excelsum): do caterpillars avoid previous leaf damage?

Wratten, S. D.; Hodge, S.; Barron, M. C. (New Zealand Ecological Society, 2000)
This study examined whether two species of lepidopteran larvae (Cleora scriptaria and Epiphyas postvittana) were deterred from feeding on the leaves of kawakawa (Macropiper excelsum) after the leaves had been damaged in three different ways: by larval fee ...
Extreme longevity of the common gecko (Hoplodactylus maculatus) on Motunau Island, Canterbury, New Zealand

Bannock, C. A.; Whitaker, A. H.; Hickling, G. J. (New Zealand Ecological Society, 1999)
The longevity of common geckos (Hoplodactylus maculatus) on predator-free Motunau Island, North Canterbury, was investigated. Sixteen of 133 individuals marked between 1967-75 were re-captured in the summer of 1996/97. A growth curve was generated to esti ...
Measuring the diversity and abundance of carabids and spiders of ten Port Hills reserves in Canterbury

Bowie Mike, H. (Lincoln University. Bio-Protection & Ecology Division, 2008-05)
The Regional Parks’ Port Hills Rangers (Greenspace Unit, Christchurch City Council) in conjunction with Environment Canterbury are ecologically restoring several reserves on the Port Hills of Canterbury. Flora and fauna (birds and invertebrates) are being ...
Small-scale species richness in forest canopy gaps: the role of niche limitation versus the size of the species pool

Duncan, R.; Buckley, H.; Urlich, S.; Stewart, G.; Geritzlehner, J. (Opulus Press, 1998-06)
The form of the relationship between local species richness and the number of species in the surrounding region can be used as a test between competing theories of community structure. For 32 canopy gaps in New Zealand Nothofagus forest, we examined the r ...
Temporal changes in height and diameter growth for two Nothofagus species in New Zealand

Runkle, J. R.; Stewart, G. H.; McClenahen, J. R. (Opulus Press, 1997-06)
We examined whether the growth dynamics of two species can explain their coexistence. In particular, we examined New Zealand forests dominated by Nothofagus fusca and N. menziesii to determine whether both species can reach the canopy in tree-fall gaps. S ...
Tree regeneration in a New Zealand rain forest influenced by disturbance and drainage interactions

Urlich, S.; Stewart, G.; Duncan, R.; Almond, P. (Opulus Press, 2005-08)
Question: Does canopy tree regeneration response to different large disturbances vary with soil drainage? Location: Old-growth conifer (Dacrydium and Dacrycarpus), angiosperm (Nothofagus and Weinmannia) rain forest, Mount Harata, South Island, New Zealand ...
Feeding frequency, meal size and chick growth in the threatened Pycroft's petrel (Pterodroma pycrofti)

Gangloff Benoit; Wilson Kerry Jayne (Lincoln University. Bio-Protection & Ecology Division, 2002)
Many species of gadfly petrel (genus Pterodroma) are threatened or endangered, including, in New Zealand, the Chatham petrel (Pterodroma axillaris), and Pycroft's petrel (P. pycrofti). Conservation actions for these species include the establishment of ne ...
