“…The hyoid apparatus, laryngeal apparatus and sternum were photographed utilizing a StereoZoom (Leica S8 Apo) with an attached digital camera (Leica DFC450 C) and Leica Application Suite X. Photographs were retouched using Adobe Photoshop 7.0 (Adobe Systems, Inc.) The generally osteological terminology followed Trewavas (1933), Duellman and Trueb (1994) and Trueb et al (2011), unless otherwise stated.…”

“…The mentomeckelians are separated from one another medially and laterally contact the dentaries and the Meckel's cartilages. Ventrally, the mentomeckelian extends a short mineralized cartilaginous process, which is called the meckelian diverticulum by de Villiers (1930) and shared by all microhylid taxa (Trueb et al, 2011).…”

“…Parker (1934) divided the Microhylidae into seven subfamilies (Dyscophinae, Cophylinae, Asterophryinae, Microhylinae, Sphenophryninae, Brevicipitinae and Melanobatrachinae) mainly based on the morphology of anterior cranial elements, the sternum and terminal phalanges. Since then, comprehensive osteological researches are mainly focused on the Gastrophryninae Fitzinger, 1843, a subfamily of Microhylidae (de Sá & Trueb, 2012;Lavilla, Vaira, & Ferrari, 2003;Lehr, Rodríguez, & Córdova, 2002;Lehr & Trueb, 2007;Trueb, Diaz, & Blackburn, 2011). The Asia-endemic Microhylinae Günther, 1858 currently contains 94 species, but only six species are comprehensively described in osteology, which is surprisingly few for this family (Chandramouli & Dutta, 2015;McPartlin, 2010;Zheng, Tang, Zhang, & Guo, 2009).…”

“…The few existing descriptions suggest that there is extensive osteological variation in Microhylinae. For instance, the premaxillae, maxillae and vomers are edentate in New World Gastrophryninae (Trueb et al, 2011), but they are dentate in Madagascar Cophylinae (Scherz et al, 2016(Scherz et al, , 2015. In Microhylinae, these elements are dentate in Glyphoglossus (Fei, Hu, Ye, & Huang, 2009;McPartlin, 2010), whereas those of Microhyla and Uperodon are edentate (Chandramouli & Dutta, 2015;Zheng et al, 2009).…”

“…Even in the same genus, the omosternum is present in Microhyla butleri, whereas it is absent in M. fissipes and M. heymonsi (Zheng et al, 2009). Obviously, more investigations on osteology of Microhylinae are needed and will give insights into the systematics, trait evolution and functional adaptions of this diverse group (McPartlin, 2010;Trueb et al, 2011).…”

Osteology of vertebrates plays an indispensable role in taxonomy, form‐function evolution and ecological adaptations. The Asian narrow‐mouth toad genus Kaloula is an interesting group that is known for many species having a fossorial life. However, to date, there has been no comprehensive osteological account of Kaloula. Herein, we present the osteology of K. borealis with the help of micro‐CT scanning and double‐staining technologies, which is the first detailed osteological description of the genus. Osteological comparisons with other members of Microhylinae indicate that K. borealis is characterized by the following traits: skull obviously wider than long; suture between frontoparietals narrow; parasphenoid posterior to vomer; premaxilla, maxilla and vomer edentate; clavicles absent; procoracoids small; omosternum and sternum cartilaginous; crista femoris present and large; femur longer than tibiofibula; prehallux including one element. Remarkably, the species possesses a series of osteological specializations that probably are adaptations for the hindlimbs‐first burrowing and a fossorial life, including stout hindlimb, robust crista femoris, tibiofibula shorter than femur, enlarged prehallux, long anterior ramus of the pterygoid and branched bronchial processes of the cricoid. These findings will contribute to the systematics of microhylids and evolutionary interpretations of the osteological adaptation to fossorial life.

Larval anurans follow predictions of stoichiometric theory: implications for nutrient storage in wetlands

2021

Ecological stoichiometry provides a framework to predict how animals regulate nutritional balances within their tissue and, as a result, how animal biomass affects ecosystem processes through nutrient cycling. However, most interspecific and developmental stoichiometric studies in animals focus on invertebrates, and the few vertebrate studies are largely fish‐centric. Larval anurans are ideal vertebrates to test predictions of developmental and interspecific stoichiometry as they undergo a complex development, exhibit broad arrays of life‐history traits, and can constitute high animal biomass in wetlands, implying major roles in wetland nutrient storage and cycling. We examined (1) patterns of body stoichiometry across larval developmental stages within multiple anuran species, (2) whether key predictors of stoichiometric change, specifically body size, developmental period, and breeding season, influence interspecific stoichiometric variation, and (3) natural magnitudes and fluctuations of larval anuran nutrient storage in geographically isolated wetlands (GIWs). We measured carbon (C), nitrogen (N), and phosphorus (P) tissue content in larval anurans across five developmental stages within 11 species collected from four GIWs to examine patterns of developmental and interspecific stoichiometry. Within species, we found broad developmental stoichiometric patterns in which later developmental stages were lower in %N, but higher in %P than earlier stages. Patterns in %C were inconsistent but were generally lower in later stages, while tissue C:N ratios increased, and C:P and N:P decreased in later developmental stages. Interspecific stoichiometric variation was partially explained by body size and developmental period which positively affected %C and C:N ratios. We observed spatial and temporal fluctuations in species‐specific biomass which dictated nutrient storage patterns within larval anuran assemblages, though stoichiometric identity played a major role. Our estimated magnitudes of larval anuran areal nutrient storage also greatly exceeded that of other wetland fauna with the maximum estimated areal P storage reaching over 200 times that of a similar‐density co‐occurring invertebrate group. These results highlight stoichiometric patterns of development and interspecific variation in a diverse group of amphibians while providing critical baseline information for elucidating the role of anurans in wetland nutrient dynamics.

The external morphology, internal oral morphology, the chondrocranium and the hyobranchial apparatus of Elachistocleis bumbameuboi, E. cf. piauiensis, E. cesarii and E. bicolor are described and compared with each other and with other species of microhylids using available descriptions from the literature. The general morphology of Elachistocleis species is conservative in many aspects. Differences between species are subtle and are found in the body shape, the edge of the snout, fin height, if the lateral line is evident, the presence of regular pustules in the buccal roof arena, the posterolateral edge of the cartilago suprarostralis, the shape of the fenestra in the occipital region, presence or absence of fenestra hypophysea, the margin of the processus antorbitalis, expansions in the ventrolateral process, the shape and inclination of the fenestra subocularis, whether the subotic process is single or slightly bifid, and the inclination of the processus anterolateralis hyalis.
