An ecologist has been reading the literature on the subject of factors affecting growth and metamorphosis of tadpoles in ponds. Some frog species (e.g. Hyla gratiosa) reproduce in ponds that are ephemeral (i.e. they dry up from time to time), while other frog species (e.g. Hyla cinerea) reproduce in ponds that are permanent.

The ecologist would like to explore these ideas and conduct some experiments.
