Variation of growth rate and survival in embryos and larvae of Rana temporaria populations from the Pyrenees

Neus Oromi, Sebastià Camarasa, Isabel Sanuy, Delfi Sanuy. Acta Herpetologica. Vol 10, No 2 (2015). Variations on embryonic and larval life history traits of ectotherm organisms are strongly affected by temperature conditions. However, these effects can vary between species and populations depending on the mechanisms that act in a determinate local habitat. In the present study, we analysed the effects of temperature on several embryonic and larval traits (survival, development and growth rate until the metamorphosis) of Rana temporaria in two populations living at different altitude (1540 and 2100 m) in the Pyrenees.
