The economic impact of failures in plant protection to New Zealand
(PeerJ Preprints, 2013-12-04)
Plant weeds, pests and diseases comprise significant threats to pastoral agriculture in New Zealand. The extent of damage incurred by New Zealand’s agricultural industry from these weed and pest threats varies significantly ...
Monitoring and enhancing the lake’s ecosytem services
Key topics of this talk include what are ecosystem services, the current state of Lake Ellesmere and who is monitoring it. Work WET is undertaking is discussed along with which ecosystem services associated with riparian ...
From poachers to gamekeepers: perceptions of farmers towards ecosystem services on arable farmland
(International Journal of Agricultural Sustainability., 2007)
Management of ecosystem services (ES) is vital to maintain and improve the productivity of agricultural systems in order to meet the food demands of a growing human population. However, some land management practices can ...
Using choice modeling to value ecosystem services on arable land
(Lincoln University., 2005-02)
The objectives are to more accurately measure values of non-market ecosystem services (ES) on New Zealand arable land by estimating values of: gas regulation (greenhouse gas emissions); waste treatment (nitrogen leaching); ...
The effect of seed moisture content and the duration and temperature of hot water treatment on carrot seed viability and the control of Alternaria Radicina
(Lincoln University, 2005)
Hot water treatment of seeds to control seedborne pathogens is an important tool for organic seed production. Reducing seed moisture content may have the potential to increase carrot (Daucus carota L. var. sativus D.C.) ...
Population regulation in insect herbivores - top-down or bottom-up?
(New Zealand Ecological Society, 1992)
Recent evidence points to the plant's being a much more limited resource than previously expected. In addition to the restraints on feeding and population growth imposed by such factors as leaf toughness, the physical ...
