Pond characteristics influence the intraspecific variation in the morphometry of the tadpoles of two species of Dendropsophus (Anura: Hylidae) from the Cerrado savanna of northeastern Brazil.

Spatial variation in the environment may be an important source of morphological variation in many organisms. Tadpoles are valuable model organisms for studies of morphological variation, and in particular, the evaluation of the relationship between environmental and morphological variables. In heterogeneous environments, such as the temporary ponds found in the Cerrado savanna of central Brazil, understanding how environmental variables influence the morphological variation found in tadpole populations can provide important insights into this phenomenon.
