A case for multi-species management of sympatric herbivore pest impacts in the central Southern Alps, New Zealand
(New Zealand Ecological Society, 2000)
Five herbivorous introduced mammals are sympatric in the central Southern Alps. All of these species have the potential to affect conservation values, yet the Department of Conservation at present monitors and mitigates ...
Water and livelihoods : a participatory analysis of a Mexican rural community
(Lincoln University, 2000)
Over 70% of Mexican farms produce only for self-subsistence and lack the necessary economies of scale to be commercial. In the arid and semi-arid regions of the country, which represents 52% of Mexico’s total land, farming ...
The effects of soil manganese on the availability of soil cobalt for pasture uptake in New Zealand soils
(Lincoln University, 2000)
The effects of soil manganese on soil cobalt availability for plant uptake were studied systematically through various chemical extractants, sequential chemical fractionation, glasshouse pot trials and field monitoring ...
To study stomatal conductance at different leaf positions and xylem flow rate at different depths in the apple branch
(Capricorn Publications, 2000)
The influence of leaf position (age) on the shoot on stomatal conductance and depth on xylem flow rate in apples (Malus pumila) MM106 cv. Gala branches were studied at Lincoln University, Canterbury, New Zealand. Leaf ...
Predator interactions within a trophic level : Phalangium opilio L. (Arachnida: Opiliones) and mites (Arachnida: Acari)
(Lincoln University, 2000)
This study investigated commensal feeding interactions between the European harvestman (P. opilio L.) and the predatory mites Balaustium spp. and Anystis baccarum L. It also investigated the feeding behaviour of P. opilio. ...
Influence of sowing date and irrigation on the growth and yield of pinto beans (Phaseolus vulgaris) in a sub-humid temperate environment
(Cambridge University Press, 2000-01)
The growth and yield of pinto beans (Phaseolus vulgaris L.) cv. Othello in response to a total of six sowing dates (from October to December) and irrigation was examined over two seasons in Canterbury, New Zealand. In ...
Application of capillary electrophoresis to anion speciation in soil water extracts: II. Arsenic
(Soil Science Society of America, 2000)
A method has been developed for the speciation of arsenic (AsO₂⁻, AsO₄³⁻, and dimethylarsinic [DMA]) in natural soil solutions from contaminated sites in Australia. The separation of these anions was achieved by capillary ...
Burrow competition between broad-billed prions (Pachyptila vittata) and the endangered Chatham petrel (Pterodroma axillaris)
(Department of Conservation, 2000-12)
The endangered Chatham petrel (Pterodroma axillaris) competes for nesting burrows with the locally abundant broad-billed prion (Pachyptila vittata) at its only breeding site on South East Island, Chatham Islands. Prions ...
Trial of burrow flaps to protect petrel chicks
(2000)
Burrow competition between the critically endangered Chatham petrel (Pterodroma axillaris) and the locally abundant broad-billed prion (Pachyptila vittata) is the main cause of Chatham petrel chick mortality, and in an ...
Processes governing phosphorus availability in temperate soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2000)
Phosphorus losses from agricultural soil to water bodies are mainly related to the excessive accumulation of available P in soil as a result of long-term inputs of fertilizer P. Since P is a nonrenewable resource, there ...
