Abstract:

Brown frog data from the 3rd National Ecosystem Survey (2006 ~ 2013) were used for Amphibians, which are known as the Edible Frog. Data on distribution type among GIS factors in the Brown frog Recorded of South Korea were generated. As a result, distribution types were generated for 6,207 Brown frogs

Abstract:

Although the phylogenetic relationship of Western Palearctic brown frogs has been repeatedly studied, the taxonomic status and phylogenetic relationship of Anatolian-Hyrcanian brown frogs is still not fully resolved. Here, we assess the phylogenetic status of these species among Western Palearctic brown frogs with special emphasize on Iranian populations based on two partial mitochondrial DNA sequences (16S rRNA and cytochrome b genes) and the application of a molecular clock. Our results clearly show that Western Palearctic brown frogs underwent a basal radiation in to two main monophyletic c

Abstract:

The Cordillera de los Andes is one of the most important regions for biodiversity. Among amphibians, many endemic species of terrestrial-breeding frogs have recently been discovered. Herein we describe Phrynopus sancristobali from the Andes of southeastern Peru based on molecular and morphological data. The new species is known from the ecotone between humid puna and montane forest at 3910 m a.s.l. on the left side of the Apurímac Valley in the Department of Ayacucho. The new species differs from congeners by having dorsum bearing pustules and light brown with dark brown reticulations surround

Abstract:

Larval amphibians are especially likely to encounter variation in temperature and resource availability because they live in a variety of aquatic habitats. In this study, plasticity in growth rates, survivorship, age and size at metamorphosis were examined in the Chinese brown frog (Rana chensinensis) under different combinations of rearing temperature and food level. Tadpoles reared at 23.2°C had larger mass at metamorphosis and a longer larval period than tadpoles reared at 25.3 and 28.1°C. High food level shortened the larval period and produced a larger size at metamorphosis. The interacti

Abstract:

Well-controlled development leads to uniform body size and a better growth rate; therefore, the ability to determine the growth rate of frogs and their period of sexual maturity is essential for producing healthy, high-quality descendant frogs. To establish a working model that can best predict the growth performance of frogs, the present study examined the growth of one-year-old and two-year-old brown frogs (Rana dybowskii) from metamorphosis to hibernation (18 weeks) and out-hibernation to hibernation (20 weeks) under the same environmental conditions. Brown frog growth was studied and mathe

This is the first record of a Green Frog consuming a bat species in Canada.

The new species is diagnosed from all its congeners by having one or two tubercles on the upper eyelids; distal phalanges strongly T-shaped; phalangeal formula on hands 2-2-3-3; phalangeal formula on feet 2-2-3-4-3; heel with a small subconical tubercle; disc on all toes with papillae; dorsum brown or brown with gray, with V-shaped inverted or scattered irregular darker marks. We include a detailed description of its osteology and a study of its phylogenetic relationships. Fi

Abstract:

We describe a new species of nurse-frog (Aromobatidae, Allobates) from northwestern Brazilian Amazon. Allobates juami sp. nov. is distinguished from similar congeneric species by the combination of the following characters: body-size range (snout-to-vent length 17.5–18.5 mm), lack of dark pigments on ventral surfaces of male specimens, dorsal color pattern (predominantly solid dark brown, but conspicuously light brown over snout and urostyle regions), presence of conspicuous pale dorsolateral and ventrolateral stripes, and presence of a diffuse pale paracloacal mark.

Abstract:

Based on molecular evidence and morphological data, we describe a new species Raorchestes yadongensis sp. nov. from Yadong County, Xizang Autonomous Region, China. The new species can be distinguished based on a combination of the following characters: (1) small body size, SVL 17.8–24.1 mm in adult males; (2) head wider than long; (3) eye diameter about three times as much as tympanum diameter; (4) tympanum distinct; (5) fingers with rudimentary webbing and narrow lateral dermal fringes; relative finger lengths I < II < IV < III; number of subarticular tubercles in fingers 1, 1, 2, 1;

Abstract:

Populations of phytotelmic frogs from northern Madagascar assigned to Guibemantis (Pandanusicola) pulcher are known to differ genetically from populations further south in the eastern rainforest belt of the island, but to date, their status has not been analyzed in depth. We combined molecular genetic data with an examination of color pattern to clarify the taxonomy of these frogs. DNA sequences of both mitochondrial and nuclear-encoded genes were consistently differentiated between the northern populations and those occurring further south.

Abstract:

Digestion of Rana graeca italica DNA with Asp718I produces highly repetitive fragments of 281 and 385 bp that were cloned and sequenced. The shorter fragment corresponds to the unit repeat (RgiS1b) of a satellite DNA. The longer fragment was found to be part of a 494-bp repeat of another satellite DNA (RgiS1a) that was cloned intact as an EcoRV fragment. RgiS1b is 97% homologous to RgiS1a, from which it seems to be derived by a single deletion. Among all species tested, only the related brown frog Rana dalmatina contained homologous repetitive DNA. The overall number of RgiS1a and RgiS1b repea

Abstract:

AbstractIt is well known that female adults of frog-biting midges (Corethrellidae) are attracted by anuran mating calls. However, the role of host-emitted cues other than mating calls in determining the level of attraction remains poorly understood. Here, we performed field playback experiments to test how the host-seeking behaviour of Corethrella Coquillett is influenced by different sound stimuli: mating call of a tree frog, cricket call, and no sound. Then, after long-distance host detection, we evaluated if Corethrella can distinguish landing sites by using at short distance the colour and

It belongs to the Osteocephalus mimeticus species group and is the sister species of O. mimeticus. It is most similar to three species with predominantly dark irises, tuberculate dorsal skin, and brown dorsal coloration: O. festae Peracca, 1904, O. mimeticus Melin, 1941, and O. verruciger Werner,
