Predicting citrus greening disease
Citrus greening disease (huanglongbing) affects many parts of citrus trees and has devastating consequences for industry. To what extent can starch content in citrus leaves be used to predict if a tree is infected with huanglongbing?
Butterfly abundance
To what extent can roadside areas provide habitat for butterflies, and what effect do different mowing intervals have on these areas?
Reducing Mowing Frequency Increases Floral Resource and Butterfly (Lepidoptera: Hesperioidea and Papilionoidea) Abundance in Managed Roadside Margins
Roads are common in natural landscapes and can have significant impacts on wildlife. Most studies have focused on vertebrates and …
