Influence of ripening grape compounds on behavioural responses of birds
(Lincoln University, 2004)
Vineyards in New Zealand suffer bird damage caused by several avian species, including blackbirds and silvereyes. The introduced European Blackbird takes whole grapes which reduces yield. The self-introduced Australasian ...
Interactions between tourists and the natural environment : impacts of tourist trampling on geothermal vegetation and tourist experiences at geothermal sites in Rotorua
(Lincoln University. Tourism Research and Education Centre, 2000-02)
The main objective of this research was to evaluate tourist impacts on geothermal vegetation and to examine visitor's attitudes towards their impacts on vegetation.
Two commercially operated sites near Rotorua were selected ...
Effects of 15N-labelled crop residues and management practices on subsequent winter wheat yields, nitrogen benefits and recovery under field conditions
(Cambridge University Press, 2001-02)
Nitrogen-15 enriched ammonium sulphate was applied to micro-plots in a field in which two leguminous (white clover and peas) and two non-leguminous (ryegrass and winter wheat) crops were grown to produce ¹⁵N-labelled crop ...
Comparison of measured and EF5-r derived N₂O fluxes from a spring-fed river
(Blackwell Publishing, 2006)
There is considerable uncertainty in the estimates of indirect N₂O emissions as defined by the Intergovernmental Panel on Climate Change's (IPCC) methodology. Direct measurements of N₂O yields and fluxes in aquatic river ...
Lime and soil moisture effects on nitrous oxide emissions from a urine patch
(Soil Science Society of America, 2004)
Liming has been mooted as a mitigation option for lowering soil N₂O emissions. This study investigated the effect of soil pH and soil water content on N₂O and N₂ emissions following the addition of synthetic urine (500 kg ...
Estimates of the nutritional cost of the development of immunity to gastrointestinal parasites in sheep
(Lincoln University, 2005)
This thesis describes a series of three experiments designed to estimate the nutritional cost of the immune response to the gastrointestinal nematodes Trichostrongylus colubriformis and Teladorsagia circumcincta in sheep. ...
The human face of once-a-day milking
(Lincoln University. Agriculture and Life Sciences Division, 2007-10)
This report concerns exactly what the title The Human Face of Once-a-Day Milking
suggests: the impact of Once-a-day milking on farmers, their families and staff. It is a
document about people: their needs, values, and the ...
The effect of vaccinating infection during pregnancy and dietary protein supply on the peri-parturient immune response of sheep to infection with Teladorsagia circumcincta and Trichostrongylus colubriformis larvae
(Cambridge University Press, 2007-03)
It is well established that dietary protein supply can influence the peri-parturient breakdown of immunity to nematode parasites
but there is no information on the importance of exposure to nematode larvae during pregnancy ...
Leptin concentrations and the immune-mediated reduction of feed intake in sheep infected with the nematode Trichostrongylus colubriformis
(Cambridge University Press, 2009)
The hypothesis that increases in the concentration of the anorectic peptide leptin may be responsible for the immune-mediated reduction in feed intake (FI) during gastrointestinal parasitism in sheep was investigated. In ...
A history of grape production and winemaking in Canterbury, New Zealand 1840-2002
(Lincoln University. Farm and Horticultural Management Group, 2002)
Grapes were first planted in Canterbury in 1840, but commercial production only began
in 1978. This research paper examines the history of grape and wine production in
Canterbury. It considers the different factors ...
