Temporal variation in predation risk: stage-dependency, graded responses and fitness costs in tadpole antipredator defenses
Article Abstract:
The strongest antipredators behaviors are expected when periods of high risk are short and infrequent are a prediction in a laboratory experiment where common frog Rana temporia tadpoles were tested by raising form early larval stages until metamorphosis. The way tadpole shape, size and age at metamorphosis were investigated which were affected by temporal variation at predation risk.

Relatedness and competitive asymmetry -- the growth and development of common frog tadpoles
Article Abstract:
A laboratory experiment was conducted to investigate the effects of relatedness on age and size at metamorphosis in the Rana temporaria tadpoles. It was concluded that increased relatedness decreased variability among individuals, but did not greatly affect growth and development of the tadpoles.

Influence of seasonal time constraints on growth and development of common frog tadpoles: a photoperiod experiment
Article Abstract:
Research indicates that unlike insect species, amphibian larvae are not as significantly affected by photoperiodic cues. Data were obtained from two populations of Rana temporaria tadpoles subjected to different photoperiodicity treatments in a laboratory setting.
