- Summary
- "In order to better understand the evolution of miniaturization in Acris blanchardi, a North American Hylid with a unique life history and of ecological interest in the United States. The development and ossification sequences of 48 larvae, 5 juveniles and 5 adult A. blanchardi were examined. The adult was described by Maglia et al. (2007) to be a miniature and to display morphological novelties. In addition, 44 larvae, 2 juvenile and 5 adults of Pseudacris crucifer a closely related frog that has been suggested to be a miniature, were examined. The cranial and postcranial adult elements of this species, as well as development and ossification of the larvae were described. The onset of ossification is described for both species and, to better understand timing relative to other hylids, they are compared to a non-miniature, Hyla lanciformis. Ossification of the cranial elements in A. blanchardi begins at similar Gosner Stages as Hyla lanciformis, but most elements never fully ossify. P. crucifer begins ossification of cranial elements much later in development but continues ossification longer and ossifies more completely. In addition to poor ossification, A. blanchardi also adds novel endochondral ossification and random mineralization to the cranium to support under-ossified elements such as the nasals and otic capsule. Based on these results, the patterns of ossification leading to miniaturization in A. blanchardi are revealed, and no evidence of miniaturization in P. crucifer was discovered"--Abstract, p. iv
