Abstract

Rates of development of ova and the first three larval stages were determined in some constant-temperature regimes for British, Icelandic, South-Swedish and Swiss populations. Comparison with data for a Finnish rock-pool population revealed poorer tolerance of high temperatures in larvae from the northern and mountain habitats. At lower temperatures no differences could be detected between the populations. The rates of development of the ova of different populations did not differ.
