Tyler Grant, PhD
Dr. Tyler Grant is a Biologist at the USGS Columbia Environmental Research Center.
Tyler has conducted research on flat-tailed horned lizards population dynamics, anuran community dynamics, and monarch butterfly spatial use. Currently he is conducting research on methods to control invasive carp. Previously, Tyler completed a Post-doctoral Research Associate position conducting spatially explicit modeling of monarch butterfly habitat use, survival estimation, and insecticide effects.

Juvenile Virile Crayfish (Faxonius virilis) length, weight, and consumption after a 28-day sublethal nickel exposure with associated water quality data Juvenile Virile Crayfish (Faxonius virilis) length, weight, and consumption after a 28-day sublethal nickel exposure with associated water quality data
Data was collected in association with the exposure of aqueous nickel (NiCl2-H2O) to juvenile crayfish (Faxonius virilis) for 29 days at different concentrations to observe any differences in growth (after 28 days) and food consumption (on day 29). Data for the growth component of the study included crayfish wet weight (initial and final), final carapace length, and crayfish sex. The...
