Molecular methods for differentiating Phragmites australis subspecies and identification of hybrid stands in the Upper Midwestern United States

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise In North America, Phragmites australis (common reed) has drawn a great deal of research attention. Non‐native P. australis subsp. australis is a noxious weed that has locally displaced native P. australis subsp. americanus in some areas.

Impact of Tile Drainage on Evapotranspiration in South Dakota, USA, Based on High Spatiotemporal Resolution Evapotranspiration Time Series From a Multisatellite Data Fusion System

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Soil drainage is a widely used agricultural practice in the midwest USA to remove excess soil water to potentially improve the crop yield. Research shows an increasing trend in baseflow and streamflow in the midwest over the last 60 years, which may be ...

Spatio‐Temporal Assessment of Fish Biodiversity in High‐Density Cascade Dam Rivers Using Environmental DNA Metabarcoding

open access: yesBiological Diversity, EarlyView.
This study employed eDNA technology for biodiversity surveys and conducted high‐density spatiotemporal eDNA sampling to evaluate ecosystem‐scale patterns across temporal, spatial, and habitat dimensions. We identified 97 fish species from 12 orders, 29 families, and 71 genera using eDNA technology. Spatially, fish diversity indices were correlated with

Improving crop condition monitoring using phenologically aligned vegetation index anomalies – A case study in central Iowa

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Timely monitoring of crop conditions is essential for optimizing and assessing agricultural management. Vegetation indices (VIs) derived from remote sensing data can be useful for assessing crop conditions on a large spatial scale.
