Non-destructive detection of water stress and estimation of relative water content in maize
[1] Non-destructive estimation of leaf water content provides vital information about vegetation productivity. We report here on controlled seven day experiments using greenhouse-grown maize. FiftyExpand

Elements of an Integrated Phenotyping System for Monitoring Crop Status at Canopy Level
Great care is needed to obtain spectral data appropriate for phenotyping in a scientifically rigorous manner. This paper discusses the procedures and considerations necessary and also suggestsExpand

Remote sensing of biodiversity: Soil correction and data dimension reduction methods improve assessment of α-diversity (species richness) in prairie ecosystems
Abstract Hyperspectral data, with their detailed spectral information at different wavelengths, offer multiple ways to assess biodiversity. One approach, known as the “spectral variation hypothesis”Expand

Seasonal Variation in the NDVI-Species Richness Relationship in a Prairie Grassland Experiment (Cedar Creek)
TLDR
We show that NDVI,which is strongly associated with vegetation percent cover and biomass, is related to biodiversityfor this prairie site, but it is also strongly influenced by other factors, including canopy growthstage, short-term water stress and shifting flowering patterns. Expand

Proximal sensing to detect symptoms associated with wheat curl mite-vectored viruses
The wheat curl mite (WCM) is microscopic, and therefore mite movement is difficult to track in the field. However, the virus complex it transmits causes observable and measurable changes toExpand

Network requirements for sensor accuracy and precision: a case study to assess atmospheric variability in simple terrain
This simulation-based study is an effort to develop design requirements for a hypothetical network of instruments to measure average atmospheric variability over a relatively simple terrain. AExpand

Detecting prairie biodiversity with airborne remote sensing
Abstract This study assessed the application of airborne imaging spectroscopy to monitor α-diversity in restored grassland plots. The study site was located within the Central Platte River ecosystem,Expand

Influence of species richness, evenness, and composition on optical diversity: A simulation study
Abstract While remote sensing has increasingly been applied to estimate α biodiversity directly through optical diversity, there is a need to better understand the mechanisms behind the opticalExpand
