Appendix A. Location, morphology, and environmental characteristics for four rivers used in the local adaptation experiments.

Table A1. Temperature, photosynthetically active radiation (PAR), flow rate, conductivity, pH and dissolved oxygen for four rivers were collected in July 2013. Temperature and PAR data are mean values over a 7 day period for all except two sites: Sekiu upstream (2 days) and Little Hoko upstream (1 day). Average daytime temperatures were determined from 10 minute interval readings using HOBO data loggers where daytime temperature value corresponded to a non-zero light measurement. Minimum and maximum temperatures include daytime and nighttime measurements. Flow rate was measured during 30 second increments using a Global Water flow probe. Conductivity, pH and dissolved oxygen were measured using a Hach HQ40d multiprobe. Further stream characteristics for the Pysht and Little Hoko can be found in Wootton (2012a,b).
