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 ...
The influence of Hoki fishing vessels on Westland Petrel (Procellaria westlandica) distribution at sea
(Ornithological Society of New Zealand, 1997-09)
The Westland Petrel (Procellaria westlandica) population is thought to have increased significantly in recent decades, perhaps as a result of increased food in the form of waste from fishing vessels. A survey of Westland ...
Poisoning mammalian pests can have unintended consequences for future control: two case studies
(New Zealand Ecological Society, 1999)
Vertebrate pest control operations using toxic baits can have unintended consequences for nontarget species. some of which may themselves be pests. Learned avoidance behaviour (termed 'aversion') can be induced by sublethal ...
Humic acid protonation, metal ion binding and metal complex dissociation kinetics
(Lincoln University, 1990)
Two humic acids have been studied in terms of: (i) their ability to bind H⁺, Cd²⁺ and Cu²⁺, and; (ii) the rates of dissociation of their Cu²⁺ complexes. For both Summit Hill and Waimari Peat humic acids, the protonation ...
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 ...
Risk management strategies for the long run use of resources: the impact of climate change on agriculture
(Lincoln University. Centre for Resource Management., 1992-07)
This publication is the result of a research contract completed for MAF Rural Policy Unit in 1991. The brief was to develop a policy framework to assist in the analysis of the issues raised by climate change and the ...
Monitoring the New Zealand costal policy statement: a preliminary assessment
(Lincoln University. Lincoln Environmental. Centre for Resource Management., 1994-10)
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 ...
The effect of subsoiling on plant nutrition and pasture production
(Lincoln University, 1993)
An eighteen month field trial was conducted to determine the effect of soil loosening on plant nutrition and pasture production. The field trial was conducted on an established (8 year old) mixed sward pasture. The soil ...
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 ...
