A monograph of the South Asian, Papuan, Melanesian and Australian frogs of the genus Rana / by G.A. Boulenger.

Influence of habitat parameters on common skipper frog (Euphlyctis cyanophlyctis) in Chittagong

“…AT had significant influence in all the three ponds (maximum 54% at S2, r = 0.737**, Table 1). The influence of AT on Ec has also been recognized by other workers (Boulenger, 1920;Mohanty-Hejmadi 1976, Jangir 2005). The other three, viz., WT, FCO 2 and Zp_den, were significant only each at one of the three ponds -39, 31 and 44% in S2, S3 and S1, respectively (Table 1).…”

High level of cryptic species diversity revealed by sympatric lineages of Southeast Asian forest frogs

“…We sampled frogs from across Southeast Asia that were identified in taxonomic studies on the basis of morphology as O. livida and R. chalconota (Boulenger 1920;Taylor 1962;Inger 1966;Inger & Chanard 1997;Bain et al 2003). We sequenced and analysed 2150 aligned characters of mitochondrial (mt) DNA (partial COXIII, complete tRNA Gly , complete ND3, partial tRNA Arg , partial 16S, partial tRNA Met , complete ND2, and partial tRNA Trp genes) from frogs morphologically resembling O. livida and 1082 aligned characters of mt DNA (partial COXIII, complete tRNA Gly , complete ND3, partial tRNA Arg , partial 16S genes) from frogs morphologically resembling R. chalconota.…”

“…Odorrana livida was originally described from Myanmar and has been reported from India to Vietnam (Bain et al 2003). Rana chalconota was originally described from Java and has been reported from peninsular Thailand, peninsular Malaysia, Sumatra and Borneo (Boulenger 1920;Iskandar & Colijn 2000).…”

Supplemental Material for 'The amphibian tree of life. (Bulletin of the AMNH ; no. 297)'

“…Because of the character conflict of omosternum shape and life-history, Brown (1952) regarded Batrachylodes as related either to ''Hylarana'' (exotrophic, entire omosternum) or to the Ceratobatrachus group (direct-developing, forked omosternum). treated Batrachylodes as a member of Raninae, although Boulenger (1920) had noted the intraspecific plasticity of omosternum shape, the only evidence supporting placement of Batrachylodes in Raninae. This arrangement was accepted by , although subsequently, transferred Batrachylodes out of Raninae and into Ceratobatrachinae, presumably on the basis of the direct development.…”

“…Although considered Amolops (sensu stricto), Amo, Huia, and Meristogenys to be subgeneric parts of a monophyletic genus Amolops, other authors (e.g., Yang, 1991b) Staurois: The definition of Staurois (digital discs broader than long; T-shaped terminal phalanges in which the horizontal part of the T is longer than the longitudinal part; outer metatarsals separated to base but joined by webbing; small nasals separated from each other and frontoparietal; omosternal style not forked ) has also been used to define Hylarana (Boulenger, 1920;see below). Although some larval characters are shared among species of Staurois (deep, cup-like oral disc in the tadpole, no glands or abdominal disc in tadpole; , the diagnostic value of these characters is unknown due to the large number of ranid species whose adults are morphologically similar to those of Staurois, but whose larvae remain undescribed.…”
