  1. Number of females and males used to generate embryos, fertilization and survival rates until hatching in the lab-reared control groups, average temperature (°C) and day degrees at each location between time of burial and retrieval, location-specific and population-specific survival rates, rates of hatching among the survivors, and rates of missing eggs at retrieval from streams (‘lost’). The last column shows mean population egg diameter in mm (±SD).
