Variation in cool temperature performance between populations of Neochetina eichhorniae (Coleoptera: Curculionidae) and implications for the biological control of water hyacinth, Eichhornia crassipes, in a temperate climate

Biological control (Print), 2019
Biological control of water hyacinth, Eichhornia crassipes, has resulted in variable outcomes in temperate regions where cool climates are thought to limit population growth and performance of the biological control agents.

A Comparison of Regression Tree Approaches to Modelling the Efficacy of Water Hyacinth Biocontrol Using Multitemporal Spectral Datasets

Journal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018
Water hyacinth (Eichhornia crassipes) is an exotic plant species that is effectively controlled by Neochetina spp. weevils. This study is aimed at determining if spectroscopic data may be utilized to predict insect‐induced stress on water hyacinth plants.

The Impact of Simulated Spectral Noise on Random Forest and Oblique Random Forest Classification Performance

Journal of Spectroscopy, Volume 2018, Issue 1, 2018., 2018
Hyperspectral datasets contain spectral noise, the presence of which adversely affects the classifier performance to generalize accurately. Despite machine learning algorithms being regarded as robust classifiers that generalize well under unfavourable noisy conditions, the extent of this is poorly understood. This study aimed to evaluate the influence
