International Journal of Scientific and Research Publications, Volume 4, Issue 5, May 2014 1 ISSN 2250-3153 Assessing feeding habits of tadpoles of Leptobrachium smithi (Matsui et al. 1999) during different development stages: a qualitative and quantitative study from Rosekandy Tea Estate, Cachar, Assam Pammi Singh*, Mithra Dey* and S.N. Ramnujam** *Department of Ecology and Environmental Science, Assam University, Silchar. ** Department of Zoology, NEHU, Shillong, Meghalaya. Abstract- Anuran tadpoles develop in water and depend on the microhabitats of tadpoles suggested by [9]. Diet is especially food available in the system for nourishment and energy important in tadpoles because they complete their life cycle in necessary for completion of their life cycle. Tadpoles of short-lived aquatic environments i.e. ephemeral ponds and Leptobrachium smithi were collected from permanent running tadpoles need to consume food that will ensure their water systems from Rosekandy Tea estate in Cachar district, metamorphosis prior to the drying up of the pond. Some tadpoles Assam. Taxonomic identification of the tadpoles was done by rely on carnivory to reach their metamorphic state. Many rearing them to adult stage under laboratory condition. Physico- tadpoles are grazers, feeding from the substrates in aquatic chemical variables of water from where the tadpoles are systems [4].

E-mail: [email protected], [email protected] Abstract Two new species, Megophrys acuta sp. nov. and Megophrys obesa sp. nov., are described based on a series of specimens collected from Heishiding Nature Reserve, Fengkai County, Guangdong Province, China. They can be distinguished from other known congeners occurred in southern and eastern China by morphological characters and molecular divergence in the mitochondrial 16S rRNA gene. M. acuta is characterized by small and slender body with adult females measuring 28.1–33.6 mm and adult males measuring 27.1–33.0 mm in snout-vent length; snout pointed, strongly protruding well be- yond margin of lower jaw; canthus rostralis well developed and sharp; hindlimbs short, the heels not meeting, tibio-tarsal articulation reaching forward the pupil of eye. M. obesa is characterized by stout and slightly small body with adult fe- males measuring 37.5–41.2 mm, adult male measuring 35.6 mm in snout-vent length; snout round in dorsal view; canthus rostralis developed; hindlimbs short, the heels not meeting, tibio-tarsal articulation reaching forward the posterior margin of eye. -

The objective of this study was to determine the prevalence of and the need for establishing a surveillance system for monitoring chytridiomycosis in fi ve national zoos and fi ve free ranging protected areas across Thailand. A total of 492 skin swab samples were collected from live and dead animals and tested by polymerase chain reaction (PCR) for the presence of Bd. The positive specimens were confi rmed by amplicon sequencing and examined by histopathology and immunohistochemistry. From July 2009 to August 2012, the prevalence of Bd from frog skin samples was low (4.27%), monitored by PCR. All samples from live amphibians were negative. The positive cases were only from dead specimens (21/168, 12.5% dead samples) of two non-native captive species, poison dart frog (Dendrobates tinctorius) and tomato frog (Dyscophus antongilii) in one zoo. -

Several features of the larval skeleton are of inter- est, including: absence of a cartilaginous strip between the cornua trabeculae, type of articulation of cornua and suprarostrals, presence of adrostral tissues, and the condition of the otic process. By com- paring sequence of ossification events across taxa, several patterns of skeletal development for Pelobates cultripes emerge, including: conserved timing of prootic ossification, delayed onset of mentomeckelian ossification, and early formation of vomerine teeth. Several other developmental features, including the absence of a palatine (= neopalatine) bone and the formation of the frontoparietal, also are discussed.

License and terms: see end of document. Abstract Frogs (Lissamphibia: Anura) use adhesive tongues to capture fast moving, elusive prey. For this, the tongues are moved quickly and adhere instantaneously to various prey surfaces. Recently, the functional morphology of frog tongues was discussed in context of their adhesive performance. It was suggested that the interaction between the tongue surface and the mucus coating is important for generating strong pull-off forces. However, despite the general notions about its importance for a successful contact with the prey, little is known about the surface structure of frog tongues. Previous studies focused almost exclusively on species within the Ranidae and Bufonidae, neglecting the wide diversity of frogs. Here we examined the tongue surface in nine different frog species, comprising eight different taxa, i.e., the Alytidae, Bombinatoridae, Megophryidae, Hylidae, Ceratophryidae, Ranidae, Bufonidae, and Dendrobatidae. In all species examined herein, we found fungiform and filiform papillae on the tongue surface. Further, we ob- served a high degree of variation among tongues in different frogs. -
On Leptobrachium from Thailand with a Description of a New Species (Anura: Pelobatidae)
Japanese Journal of Herpetology 18 (1): 19-29., June 1999 (C)1999 by The HerpetologicalSociety of Japan On Leptobrachium from Thailand with a Description of a New Species (Anura: Pelobatidae) MASAFUMI MATSUI, JARUJIN NABHITABHATA, AND SOMSAK PANHA Abstract: We compared morphological characters among Thai populations of Lepto- brachium currently assigned to L. hasseltii or L. pullum. We also examined syn- types of the latter, which was first described from Vietnam as Megalophrys hasseltii var. pullus Smith, 1921, and designated the lectotype. The Thai populations are slightly variable in adult and larval morphology, but are collectively different from L. hasseltii (originally described from Java) or L. pullum. We therefore describe a new species, L. smithi, for those populations on the basis of the sample from Khao Chong, southern Thailand. Key words: Pelobatidae; Leptobrachium; Systematics; Thailand; Biogeography The genus Leptobrachium (sensu stricto [not 239) and Manthey and Grossmann (1997) clearly of Dubois, 1980]=subgenus Leptobrachium of presented through photographs of individuals Dubois and Ohler, 1998) is a group of pelobatid from western and northeastern Thailand, frogs characterized by a stocky body with slen- respectively. der, short hindlimbs (Inger and Stuebing, 1997; However, Smith (1921) also clearly indicated more detailed diagnosis in Dubois and Ohler, that he split M. h. var. pullus from "typical has- 1998).

Tropical forests are considered one of the most important biogeographic zones for amphibian species diversity. As a tropical country in Asia, Bangladesh implements different types of forest management practices in its forests, which might affect prevailing forest quality in the existing forest types. The current state of information on the impact of habitat alteration on amphibian species assemblages in Bangladesh is inadequate. To evaluate this, we conducted a study in Khadimnagar National Park (KNP) in north-eastern Bangladesh. We used a combination of several common amphibian study techniques in 15 pre-marked transects covering three major habitat types in KNP: forest edge, forest interior and swamp area. Twelve anuran species belonging to eleven genera and six families were recorded during the study period. Euphlyctis cyanophlyctis was the most abundant species, representing 51.7% of the recorded individuals, followed by Fejervarya spp. (18.9%); the remaining 10 species altogether recorded less than 30% of the total abundance. Duttaphrynus melanostictus, Kaloula pulchra and Raorchestes parvulus in particular occurred with very low abundance.
