“…This suggestion finds support in the observation of Rittenhouse (2007) and Lemckert et al (2006) -the habitat selections can be changed with environmental conditions. Though DO was found to be influential in the ecology of Ec by Khan et al (2012) and Akram et al (2015), it was not at all an influential factor, as explained earlier, in any of the three present sites. The highest total influence of the abiotic and biotic factors, included in the present work, on Ec was 69% (Table 1), which indicates that further study on the of Ec should be widened incorporating other related ecological factors.…”

“…It, however, should be mentioned here that the density of Ec was highest, among all the sites, at S2 which had the highest concentration of DO (Table 1). Khan et al (2012), Chowdhury and Das (2014) and Akram et al (2015) pointed out the influence of DO on the population change of Ec. Presently, with total data, the influence of DO was not significant at any of the sites.…”

“…Habitat selection of anurans is known to be influenced by environmental factors, like the abiotic temperature and pH (Banks and Beebee, *Corresponding author: wahed.chowdhury@cu.ac.bd 1987, Pope et al 2000), and the biotic like the competitors, predators, and the degree to which resources are distributed spatially (Crump 1991, Daniels 1992, Nie et al 1999, Lin et al 2008, Indermur et al 2009). Very recently, Akram et al (2015) worked on the influence of some abiotic and biotic factors on the habitat selection of some anurans in Pakistan and Lemckert (2006) worked on the correlation between frogs and pond attributes in Australia. In Bangladesh, similar works are limited to only one publication by Chowdhury and Das (2014), and two unpublished research project (Das 2013, Shil 2014).…”

Habitat selection of common skipper frog [Euphlyctis cyanophlyctis (Schneider, 1799)] was studied by a sampling (covering all the three seasons) of data collection on six abiotic (size and depth of water body, air and water temperature, dissolved oxygen and free carbon dioxide) and three biotic (plant species richness, zooplankton species richness and zooplankton density) factors of three ponds in Chittagong, Bangladesh. The discriminant analysis, cluster analysis and paired t-test of total data revealed that the three water bodies functioned as separate systems. Of the nine factors, only four (AT, WT, FCO2 and Zp_den) had individual significant influence on the frog at least at one of the ponds. However, the maximum R 2 value (0.712, p < 0.001) indicates that at least some important factors were not included in the investigation.

“…Within a site, the discriminating factors between seasonal habitat conditions demonstrated that the same factor did not characterize the habitat in every season, and each factor has differing effects on the frog population throughout the year (discriminating factors in Table 2). Similar to the present observations, low densities of this species have been described in the eastern and western corners of its range (5-10/acre in Islamabad, Pakistan, [13,38]; 10-14/acre from Chittagong, Bangladesh [39]), but the frog is widely distributed [15,[40][41][42].…”

“…For example, Bufo calamita choose breeding sites with a pH above 3.8 (3.8-6.9) [12]. Dissolved oxygen also influences the choice of breeding pools [13]. Pearman [14] studied the multilevel influence of the size of the water body-calculated from the pond surface area and depth-on tadpole populations of Rana clamitans.…”

Temporary Water Holes May Benefit the Breeding of the Common Skipper Frog Euphlyctis cyanophlyctis (Anura: Dicroglossidae)

Seasonal fluctuations in adult Euphlyctis cyanophlyctis density were recorded in two permanent ponds in Southeastern Bangladesh. From a two-year dataset of seven habitat parameters, the seasonal suitability of two different pond habitats was examined to understand these fluctuations of frog density. The combined influence of the parameters on the density was significant in all three seasons. One combination was found to be optimal: water temperature of 24 °C, a pH of approximately 6, and a water depth of 2.29 m. These conditions supported more than 24 frogs per acre in the round pond. In the forestry pond, the optimal parameters were a water temperature of 27 °C and a water depth of less than 1 m, which accommodated 27 frogs per acre. The result indicates that a slight increase in any of these parameters was found to sharply lower the accommodation capacity of the studied ponds to less than half of the aforesaid densities, especially in the rainy season. During this season, the adults were found to breed in the small waterholes adjacent to the ponds. This may be the response of anuran to temporal unsuitability, for example, the depth of water and the pH of the permanent ponds.

The current study was focused on documentation of amphibian assemblage in North Punjab and Islamabad Capital Territory, Pakistan, by using mitochondrial gene sequences of 16S rRNA. Our study entailed 37% of the known amphibian species of the country. We provided a phylogenetic analysis based on 74 newly generated mitochondrial 16S rRNAs from nine species of genus Microlyla, Duttaphrynus, Allopaa, Nanorana, Sphaerotheca, Minervarya, Hoplobatrachus, and Euphlyctis. We employed the maximum-likelihood inference and Bayesian analysis to assess the taxonomic status of the samples obtained from Pakistan, with respect to other congeneric species from surrounding regions. Our findings confirmed the taxonomic status of South Asian anuran species Duttaphrynus stomaticus, Duttaphrynus melanostictus, Microhyla nilphamariensis, Allopaa hazarensis, Nanorana vicina, Sphaerotheca maskeyi (synonym: S. pashchima), Minervarya pierrei, Hoplobatrachus tigerinus, and Euphlyctis kalasgramensis in Pakistan. We have reported new country records of genus Minervarya (M. pierrei).Minervarya pierrei was previously misidentified as Fejervarya limnocharis, due to dearth of genetic information. We provided the first genetic records of our endemic species N. vicina. The results revealed the taxonomic placement of N. vicina with respect to its congeners and validated the taxonomic status of N. vicina from its type locality (Murree) for the first time. The findings of the present study also indicated the paraphyletic relationship of A.-hazarensis with Nanorana species. So, based on our phylogenetic inferences, morphological characters, and habitat preferences, validity of generic status of A. hazarensis is undecided. As our data were not enough to resolve this issue, we suggest sequencing of additional mitochondrial and nuclear genes in the future studies to get a better resolution. We recommend carrying out extensive surveys throughout the country for proper scientific documentation of amphibians of Pakistan. Many new species, some of them might be endemic to Pakistan, are expected to be discovered, and taxonomic status of other species would be resolved.
