Grass Carp (Ctenopharyngodon idella) Egg Diameter Estimates from the Huron River (Ohio), 2022

These data include egg diameter estimates from Grass Carp (Ctenopharyngodon idella) eggs collected during bongo net sampling in the Huron River (Ohio; 41.3305, -82.5812) on May 23, 2022 near Milan, Ohio. Egg diameters were estimated from photographs using proportional relationships of pixel lengths with a known length scale bar in millimeters. Given that eggs were not perfectly spherical, egg diam

Field Site Locations from Phragmites Bioherbicide 2023 Field Experiment in Southeast Michigan

This dataset represents the locations of experimental plots that were used during the Phragmites Bioherbicide 2023 field experiment. To meet the criteria for selection, a site must have relatively dry soil with no standing water, have two or more large monotypic stands of Phragmites australis, and be easily accessible by vehicle. Experimental plots were created at these sites and one of four treat

Root and Shoot Lengths of Rice and Bermuda Grass Seedlings Inoculated with Endophytic Bacteria from Phragmites australis

These data include measurements of root and shoot lengths of Rice (Oryza sativa) and Bermuda grass (Cynodon dactylon) that were inoculated with nine endophytic bacterial isolates. The tabular data represent growth promotion and fungal infection susceptibility information. They also show the infection rate of F. oxysporum on Rice (Oryza sativa), Bermuda grass (Cynodon dactylon) and Annual Bluegrass

Autonomously Collected Benthic Imagery for Substrate Prediction, Lake Michigan 2020-2021

These data consist of down-looking images of Lake Michigan benthos, collected in 2020 and 2021 with an autonomous underwater vehicle (AUV). Information about each image (i.e., latitude, longitude, depth from surface, altitude, roll, pitch, yaw, and creation time) can be found in the associated csv file. Substrate type was divided into 9 classes based on the Coastal and Marine Ecological Classifica
