Ivermectin (22,23-dihydroavermectin B₁) is a broad-spectrum antiparasitic drug that was introduced for the control of parasitic worms and lice in sheep and cattle. This review summarises what is known about the impact of ...
Leaf damage does not affect leaf loss or chlorophyll content in the New Zealand pepper tree, kawakawa (Macropiper excelsum)
(New Zealand Ecological Society, 2000)
Kawakawa (Macropiper excelsum) is an understorey, forest tree which sustains conspicuous and substantial herbivory from the larvae of a geometrid moth, Cleora scriptaria. This study examined the relationship between leaf ...
Testing for benefit transfer in valuation of ecosystem services in New Zealand winegrowing regions
(Lincoln University. Faculty of Commerce. Department of Accounting, Economics and Finance, 2008)
Objectives of this study are to estimate average Willingness-to-Pay (WTP) of Marlborough (MARL) and Hawke’s Bay (HB) households for reductions in environmental impacts caused by winegrowing practices.
Repellency of volatile oils from plants against three mosquito vectors
Volatile oils extracted by water distillation from four plants species, turmeric (Curcuma longa), kaffir lime (Citrus hystrix), citronella grass (Cymbopogon winterianus) and hairy basil (Ocimum americanum), were evaluated ...
Potential of the beneficial fungus Trichoderma to enhance ecosystem-service provision in the biofuel grass Miscanthus × giganteus in agriculture
(Nature Publishing Group, 2016-04-27)
The sterile hybrid grass Miscanthus x giganteus (Mxg) can produce more than 30 t dry matter/ha/year. This biomass has a range of uses, including animal bedding and a source of heating fuel. The grass provides a wide range ...
Enhancing nectar provision in vineyard habitats for the endemic New Zealand butterfly, Lycaena salustius
(New Zealand Ecological Society, 2013)
Nectar is an important factor influencing the level and persistence of butterfly populations, but particular sources of nectar may not be optimal for all species. In a farmland context, it is not always clear whether nectar ...
Phenology of New Zealand Flower Thrips (Thrips obscuratus) in vineyards
(Lincoln University, 2004)
Food and nutritional security requires adequate protein as well as energy, delivered from whole-year crop production
© 2016 Coles et al.Human food security requires the production of sufficient quantities of both high-quality protein and dietary energy. In a series of case-studies from New Zealand, we show that while production of food ...
Potential ecosystem service delivery by endemic plants in New Zealand vineyards: successes and prospects
Vineyards worldwide occupy over 7 million hectares and are typically virtual monocultures, with high and costly inputs of water and agro-chemicals. Understanding and enhancing ecosystem services can reduce inputs and their ...
