Asparagus virus 2 : incidence, yield effects and transmission in New Zealand asparagus crops
(Lincoln University, 1997)
Asparagus ilarvirus 2 (AV2) occurs in asparagus crops in New Zealand and worldwide, but its effect on and spread within crops has not been reported in the literature. The causes of declining yields in asparagus crops, ...
A dendroclimatic study of Libocedrus bidwillii hook. F. (Kaikawaka)
(Lincoln University, 1995)
This thesis demonstrates some of the potential of Libocedrus bidwillii Hook. f. (Kaikawaka) for dendroclimatological research by developing tree-ring chronologies and then using these chronologies to reconstruct ...

(Lincoln University, 1990)
Anisoplaca ptyoptera Meyrick (Lepidoptera: Gelechiidae) is a stem miner which attacks some members of the tribe Cannichaelieae (Fabaceae). Carmichaelieae and A. ptyoptera are both endemic to New Zealand. Recently it was ...
Effects of predation and rabbit haemorrhagic disease on rabbit population dynamics in New Zealand
(Lincoln University, 2004)
This thesis investigated the effects of predation and a newly introduced biological control rabbit haemorrhagic disease (RHD) - on rabbit (Oryctolagus cuniculus) population dynamics in two bioclimatically diverse regions ...
The molecular genetics and diversity of the Hepatitis C virus genome
(Lincoln University, 1995)
A number of different genotypes of the Hepatitis C virus have been reported in New Zealand
(Cooper et al. 1993, Woodfield et al. 1994). However little is known about the distribution of genotypes, the extent of strain ...

The majority of Coccinellid ladybirds are beneficial to man because of their predacious nature. In 1874 Coccinella undecimpunctata Linneaus, was introduced into New Zealand, (Dumbleton 1936), as one of the first attempts ...
The effect of temperature on the biology and population ecology of Agasicles hygrophila (Coleoptera: Chrysomelidae), a biological control agent of alligator weed (Alternathera philoxeroides)
(Lincoln University, 1996)
Alligator weed, Alternanthera philoxeroides (Mart.) Griseb. (Amaranthaceae) is a perennial, stoloniferous herb which grows primarily as an emergent aquatic plant. It was first recorded in New Zealand in 1906 and is distributed ...
Effect of winter crop systems on rumen degradation and grazing behaviour of dairy cows
(Lincoln University, 2013)
Winter forage crop-fed dairy cattle excrete the largest proportion of their annual nitrogen (N) leachate from the dairy system, during the winter period. Adjusting the supply of N to carbohydrate in the diet is suggested ...
The conservation and ecology of Ischnocarpus exilis and I. novae-zelandiae, two threatened New Zealand cresses
(Lincoln University, 2002)
Sixty-five percent of New Zealand's threatened plants are herbaceous, yet herbaceous species have received relatively little research attention. Very little experimental work is done to scientifically test hypotheses thought ...
