Effects of temperature on the development of an arctic Collembola ( Hypogastrura tullbergi)
Abstract Embryonic development, juvenile moulting and growth rates, and maximum size of the arctic collembolan Hypogastrura tullbergi were investigated at 5, 10 and 15 °C in laboratory experiments. The embryonic development was also investigated at 21 °C. The lower temperature threshold of the embry...
