The monitoring of complex natural systems - aspects of ecosystem management using wetlands as examples
(Lincoln University, 1998)
The Resource Management Act (1991) created a major shift in the legislative framework for environmental management in New Zealand. The Act devolved power to local and regional government, and focused on the environmental ...
Intraspecific variation in Microctonus hyperdoae and M. aethipopides (Hymenoptera: Braconidae); significance for their use of biological control agents
(Lincoln University, 1995)
Microctonus aethiopoides Loan and M. hyperodae Loan (Hymenoptera: Braconidae; Euphorinae) are parasitoids introduced to New Zealand to assist suppression of the lucerne pest Sitona discoideus Gyllenhal and the pasture pest ...
Sorption behaviour and plant availability of copper in soils
(Lincoln College, University of Canterbury, 1988)
Some New Zealand soils were shown to have a high affinity for low concentrations of added copper. Between 95 - 100% of added copper was adsorbed by these soils. Adsorption isotherm gradients calculated using total solution ...
Tortricid moth pest management in Canterbury apple orchards
(Lincoln College, University of Canterbury, 1984)
Orchard practices and pest abundance were monitored at five sites over three seasons. Canterbury apple orchardists could produce high quality fruit with less than 1% damage using as few as four insecticide sprays per season. ...
Sulphur cycling in soil-plant-animal systems under grazed, irrigated pastures in Canterbury, New Zealand and its implication on pasture sulphur requirements
(Lincoln University, 1990)
A laboratory study was conducted to investigate whether the zinc acetate-sodium acetate (Zn-Na acetate) solution that has often been used in the Iohnson-Nishita method (1952) to trap hydrogen sulphide (H₂S) and allow more ...
Availability of phosphate fertilizers in unlimed and limed acid soils as affected by wetting and air-drying
(Lincoln University, 1991)
The interactions between air-drying and rewetting, and liming or timing of phosphate (P) fertilizer application on plant availability of monocalcium phosphate (MCP) or reactive phosphate rock (PR) fertilizers were studied ...
Genetically modified broccoli (Brassica oleracea L. var. italica) containing an antisense acc oxidase gene
(Lincoln University, 1999)
In broccoli, post-harvest senescence is rapid, with loss of chlorophyll resulting in the yellowing of sepals from immature florets. Associated with this deterioration is an increase in ethylene production. In order to delay ...
Plant parasitic nematodes: the effect of lolines.
(Lincoln University, 2008)
Grass endophytes live their entire life cycle within the aerial portion of the grass host,
with which they form a defensive mutualism. The endophyte which resides
intercellularly within the grass, synthesizes an array ...
An integrated approach to inflow forecasting for reservoir management: The upper Waitaki
(Lincoln University, 1996)
In 1992 New Zealand experienced one of its worst electricity shortages in history. This was blamed on the drought of 1991/1992 and the management of the water stored in the hydro lakes. A review committee was set up by ...
Relationships between soil water retention and soil composition
(Lincoln University, 1991)
Relationships between soil water retention and physical composition have been examined in this study, using a database of two independent sets of soils from two regions in New Zealand: Canterbury in the South Island (Set ...
