Development and survival of tadpoles and metamorphs of Rana temporaria in six boreal lakes in southern Finland

<p>We assessed the effect of water colour on the development of larval amphibian. Tadpoles of Rana temporaria were raised in experimental cages in 6 boreal lakes representing a gradient of water colour.</p> <p>The dataset includes the recording of the environmental variables in the lake during the experiment, morphometric variables for tadpoles and metamorphs, as well as tabulated data for survival analysis during the tadpole stage and to metamorphosis. The experiment took place from May to July 2023 in Evo Natural 2000 site in Finland.</p>
