The breeding biology of tree frog, Polypedates teraiensis was studied during the breeding season at Mizoram University Campus. It was found that sound production by male during the breeding season was primarily a reproductive function and advertisement calls attract females to the breeding areas and announce other males that a given territory is occupied. The aim of this study was to provide the detailed information on the breeding behaviour and the advertisement calls of Polypedates teraiensis. The morphometric measurements of the amplecting pairs (males and females) for sexual dimorphism along with clutch sizes were also studied.

Abstract Background Four ohnologous genes (sox1, sox2, sox3, and sox15) were generated by two rounds of whole-genome duplication in a vertebrate ancestor. In eutherian mammals, Sox1, Sox2, and Sox3 participate in central nervous system (CNS) development. Sox15 has a function in skeletal muscle regeneration and has little functional overlap with the other three ohnologs. In contrast, the frog Xenopus laevis and zebrafish orthologs of sox15 as well as sox1-3 function in CNS development. We previously reported that Sox15 is involved in mouse placental development as neofunctionalization, but is pseudogenized in the marsupial opossum. These findings suggest that sox15 might have evolved with divergent gene fates during vertebrate evolution. However, knowledge concerning sox15 in other vertebrate lineages than therian mammals, anuran amphibians, and teleost fish is scarce. Our purpose in this study was to clarify the fate and molecular evolution of sox15 during vertebrate evolution. Results We searched for sox15 orthologs in all vertebrate classes from agnathans to mammals by significant sequence similarity and synteny analyses using vertebrate genome databases. Interestingly, sox15 was independently pseudogenized at least twice during diversification of the marsupial mammals. Moreover, we observed independent gene loss of sox15 at least twice during reptile evolution in squamates and crocodile-bird diversification. Codon-based phylogenetic tree and selective analyses revealed an increased dN/dS ratio for sox15 compared to the other three ohnologs during jawed vertebrate evolution. Conclusions The findings revealed an asymmetric evolution of sox15 among the four ohnologs during vertebrate evolution, which was supported by the increased dN/dS values in cartilaginous fishes, anuran amphibians, and amniotes. The increased dN/dS value of sox15 may have been caused mainly by relaxed selection. Notably, independent pseudogenizations and losses of sox15 were observed during marsupial and reptile evolution, respectively. Both might have been caused by strong relaxed selection. The drastic gene fates of sox15, including neofunctionalization and pseudogenizations/losses during amniote diversification, might be caused by a release from evolutionary constraints.

The species Bucephalopsis karvei n. sp. has been described in detail and separated from the allied species. A survey of the work on Bucephalidæ has been given and the species B. magnum, B. confusus and B. minimus have been considered to be synonyms of B. garui. A key to the existing valid species of Bucephalopsis has been given.The genus Catoptroides has been merged into the synonymy of Phyllodistomum and arguments for so doing have been advanced. Revised diagnosis of Phyllodistomum has been given.Phyllodistomum shandrai n. sp. has been described and separated from the allied species. P. sp. has been briefly described. Key to the species of Phyllodistomum has been given.Paramphistomum maplestoni n. sp. and P. cuonum n. sp., have been described and separated from the allied species P. orthocœlium. A few observations on P. sp. from a wild cat and Diplodiscus amphichrus from Rana tigrina have been recorded. Paramphistomum cervi, P. sp., Cotylophoron orientalis and Gastrothylax crumenifer have been recorded from neelgai, hog deer and sable antelope respectively.Helostomatis sakrei n. sp. has been described and separated from H. helostomatis. A revised diagnosis of Helostomatis has been given.Neocladorchis poonaensis n.g., n. sp. has been described. The new genus Neocladorchis has been defined and separated from the allied genera.

Bioacoustic Analysis

Scinax hayii was described in 1909 from the municipality of Petrópolis, State of Rio de Janeiro, Brazil. Morphological variation and advertisement calls have been previously reported for other populations across the species distribution (Lutz 1973; Heyer et al. 1990; Cardoso & Andrade 1991; Pombal et al. 1995; Magrini et al. 2011; Abrunhosa et al. 2014). However, no information on calls are available from specimens recorded at the type locality, preventing the correct characterization of the species (Magrini et al. 2011). Here we describe the advertisement call and a second call type of S. hayii from Petrópolis, as a contribution towards a better understanding of the taxonomy of this species.
