“…Similarly, arboreal tadpoles of Neotropical bufonids of the genus Melanophryniscus Gallardo, 1961, did not present marked morphological differences in relation to non-arboreal close relatives that inhabit lentic and lotic environments [ 20 ], suggesting few specializations for arboreality when compared to other typical arboreal tadpoles (see [ 20 , 114 ]). Therefore, factors other than adaptations to specific microhabitats can influence the morphology of tadpoles, such as adaptations to predation/locomotion in different aquatic environments, foraging position in the water column, and phylogenetic relationships [ 20 , 21 ]. Thus, comprehensive studies are needed to evaluate the importance of tadpole traits both in the reproductive mode of B .…”

Anurans have the greatest diversity of reproductive modes among tetrapod vertebrates, with at least 41 being currently recognized. We describe a new reproductive mode for anurans, as exhibited by the Paranapiacaba Treefrog, Bokermannohyla astartea, an endemic and poorly known species of the Brazilian Atlantic Forest belonging to the B. circumdata group. We also describe other aspects of its reproductive biology, that are relevant to understanding the new reproductive mode, such as courtship behavior, spawning, and tadpoles. Additionally, we redescribe its advertisement call and extend its vocal repertoire by describing three additional call types: courtship, amplectant, and presumed territorial. The new reproductive mode exhibited by B. astartea consists of: (1) deposition of aquatic eggs in leaf-tanks of terrestrial or epiphytic bromeliads located on or over the banks of temporary or permanent streams; (2) exotrophic tadpoles remain in the leaf-tanks during initial stages of development (until Gosner stage 26), after which they presumably jump or are transported to streams after heavy rains that flood their bromeliad tanks; and (3) tadpole development completes in streams. The tadpoles of B. astartea are similar to those of other species of the B. circumdata group, although with differences in the spiracle, eyes, and oral disc. The vocal repertoire of B. astartea exhibits previously unreported acoustic complexity for the genus. Bokermannohyla astartea is the only bromeligenous species known to date among the 187 known species within the tribe Cophomantini. We further discuss evolutionary hypotheses for the origin of this novel reproductive mode.

“…Differences in larval morphology may be considerable even in closely related species with distinct reproductive modes ( e . g ., [ 19 – 21 ]). Likewise, acoustic communication represents an important evolutionary phenotype among major clades of terrestrial vertebrates, including anuran amphibians [ 22 ].…”

“…For instance, the establishment of a species in a given habitat is largely influenced by morphological features such as type of oral disc, shape of body, fin presence (McGill et al, 2006;Lavorel et al, 2007;Queiroz et al, 2015). Therefore, morphological traits are a useful character in understanding their phylogenetic, taxonomic, ecomorphological, evolutionary and functional aspects (McDiarmid and Altig, 1999;Borteiro and Kolenc, 2007;Barrasso et al, 2013;Pezzuti et al, 2016).…”

“…Although these early descriptions are a valuable source of information for several species (the only one for some of them), they usually included on a single or few individuals, without morphometrics and detailed illustrations, thus limiting intra and interspecific morphological comparisons (Borteiro and Kolenc, 2007), even the taxonomic identification (Rojas et al, 2018). Not surprisingly, re-descriptions of the morphology of the tadpoles are increasing in the last few years (Borteiro and Kolenc, 2007;Provete et al, 2012;Barrasso et al, 2013;Iop et al, 2015;Pezzuti et al, 2016;Rojas et al, 2018). Usually based in linear measurements, only a few studies have described the shape of tadpoles obtained with geometric morphometric methods (Klingenberg, 2011) as an additional factor to morphological diagnosis (Haad et al, 2011;Pezzuti et al, 2016).…”

Ecological studies testing the preponderance of environmental filters on ontogeny to explain the variation in tadpole morphology are scarce for Neotropical anurans. We used tadpoles of the stone frog Limnomedusa macroglossa (Alsodidae): (1) to assess the variation in body and tail shape; (2) to examine the effect of streamlet depth and allometry on tadpole shape, and (3) to re-describe and compare the tadpole external morphology with closely related species. We obtained the body shape and size from 150 tadpoles. The re-description was based on 57 qualitative and 24 quantitative characters, from 19 tadpoles between stages 30 and 37 and 31 to 37, respectively. Allometry was the major factor influencing the lateral view of body shape: smaller tadpoles had round bodies and eyes and nostrils positioned more laterally in comparison with larger ones. Thus, the power of ontogenetic variations reported here makes the tadpole developmental “climax” period a questionable concept that deserves additional attention. The depth gradient of streamlets also affected the shape: in shallower environments, the tadpoles presented a decrease in height of the body, fins and tail muscles, and an increase in body width. These results may indicate adaptations allowing better swimming performance in lotic environments with intense water flow. The external morphological characterization of L. macroglossa presented here differed from that previously reported, mainly due to coloration, body shape, nostril, anal tube, tail, shape and position of nostrils and snout. Additionally, we presented unknown traits for this species, making comparisons with closely related species within the Alsodidae family.
