De novo assembly and annotation of the larval transcriptome of two spadefoot toads widely divergent in developmental rate
Introduction Introduction Methods Results and Discussion Conclusion Data and materials References Most amphibian species exhibit a complex life-cycle including two or more life stages separated by an ontogenetic switch point such as hatching or metamorphosis. Adaptations to divergent environments can require the modification of the timing of such switch points and the relative investment in growth and differentiation between subsequent stages [1]. Such alterations of developmental trajectories, however, often have substantial repercussions at several organismal levels, from physiology to morphology and even genomic structure. Adaptive divergence in developmental rate tracking aquatic habitats of different duration in spadefoot toads is a well-known example of this. Spadefoot toads from Europe and ...
