Spider distribution in agroecosystems in Canterbury, New Zealand
(Lincoln University, 2000)
The spider assemblage from four shelterbelts and their adjacent grazed pastures in South Island, New Zealand was suction sampled from August 1994 to July 1995 and from March 1996 to March 1997. Spider density decreased ...
Biological control of Aphanomyces euteiches root rot of pea with spore-forming bacteria
(Lincoln University, 2001)
Spore-forming bacteria were investigated as potential biological control agents of the pea root rot fungus, Aphanomyces euteiches (Oomycete). Isolations of the bacteria were made both directly from field soils (558) and ...
Use of floral resources by the lacewing Micromus tasmaniae and its parasitoid Anacharis zealandica, and the consequences for biological control by M. tasmaniae
(Lincoln University, 2009)
Arthropod species that have the potential to damage crops are food resources for communities of predators and parasitoids. From an agronomic perspective these species are pests and biocontrol agents respectively, and the ...
Modelling the spread of invasive species across heterogeneous landscapes
(Lincoln University, 2008)
Invasive species are well known to cause millions of dollars of economic as well as ecological damage around the world. New Zealand, as an island nation, is fortunate because it has the opportunity to regulate and monitor ...
Using multi-layer perceptrons to model the Lincoln aphid data set
(Bio-Protection & Ecology Division, 2007)
This document is the initial report on a systematic approach to the application of MLP to the aphid prediction problem.
The aims of this initial work are three-fold;
to investigate the effectiveness of a particular ...
How do threats to Canterbury plants potentially lead to extinction
(Canterbury Botanical Society, 2002)
This article looks at some of the threats, decline and potential extinction facing Canterbury's unique flora. The author uses an analogy of marine disasters and extinction of biological species, as both involve similar ...
Application of diffusion laws to composting: theory, implications, and experimental testing
(Lincoln University, 2008)
Understanding the fundamentals of composting science from a pragmatic perspective of necessity involves mixtures of different sizes and types of particles in constantly changing environmental conditions, in particular ...
Comparison of multi-layer perceptrons and simple evolving connectionist systems over the Lincoln aphid data set
(Bio-Protection & Ecology Division, 2007)
This report presents two further experiments over the aphid data set. The first is an evaluation of the adaptive abilities of backpropagation of errors trained MLP and a comparison of these capabilities with the Simple ...
Spatial distribution of the rodent population at Boundary Stream Mainland Island and determination of the efficacy of different baits used for rodent control
(Lincoln University, 2008)
Poison operations are a widely used technique for rodent control in the indigenous forests of New Zealand. This study examined the bait-take and rat monitoring data obtained for continuous poison operations at Boundary ...
The impact of host-plant stress on the performance of two insect biological control agents of Broom (Cytisus scoparius)
(Lincoln University, 2005)
Weeds often grow over a wide range of environments, experiencing a number of environmental stresses with varying intensities. As a consequence these weeds will often exhibit differences in morphology and physiology. It has ...
