Lateralized motor responses in anuran amphibians — an overview of methods and perspectives of studies

Abstract

Anuran amphibians represent the most usual subjects for experimental biological research and a divergent group of extant vertebrates comprising species adapted to a variety of environments from aquatic to arboreal. Thus, they become excellent models in research of motor lateralization due to their different phylogenetic position and their anatomical and ecological diversity throughout their evolutionary history, as well as variety of locomotive habits and a diversity of limb use during walking, swimming, feeding and other activities. From the first works in mid-1990’s to the present day, a noticeable progress, a noticeable progress in the study of motor lateralization in anurans is made favored by a set of methodological approaches and their application to various species and life stages. Together, these advances foretell a plethora of interesting developments in the world of laterality research with the anuran amphibian model. Here, the discovery of right-pawedness in toads through the development of a set of different techniques to assess motor lateralization in anuran amphibians, and, as a consequence — important results revealing behavioral and morphological correlates are reviewed and discussed in evolutionary and eco-morpho-logical perspective.
