TL;DR: It is described quantitatively the advertisement calls of six species of anurans from Bali and the release call of three of these and the three release calls have not been described previously to the best of the authors' knowledge.
Abstract: We describe quantitatively the advertisement calls of six species of anurans from Bali and the release call of three of these. The advertisement calls of three of the species and the three release calls have not been described previously to the best of our knowledge. This is the first study that describes calls from anurans of the island of Bali. Advertisement call characteristics are discussed in light of within‐individual and between‐individual variation. For the three species with previously published accounts of their advertisement calls we compare the data obtained in Bali with other accounts. While Bufo melanostictus did not show a substantial difference in advertisement calls from Coorg (India), the calls of Balinese Fejervarya (Limnonectes) limnocharis show substantial differences with those recorded in Coorg (India). Furthermore, the Balinese recordings of Polypedates leucomystax are similar to recordings obtained by other authors in Negros (Philippines), the Malaysian part of Borneo, and from on...

TL;DR: Comparisons of variation in PRLR protein expression in the two species under different environments suggest that B. bankorensis is more adaptable to different environments than B. melanostictus.
Abstract: Bufo bankorensis and Bufo melanostictus, the only two species of Bufonidae genus in Taiwan, live in habitats that differ in altitude and humidity. This study tested the hypothesis that prolactin receptor (PRLR) expression responds to environmental change. Western blot analysis showed that the PRLR protein was widely distributed in brain, lung, liver, kidney, dorsal skin and ventral skin of toads. The level PRLR protein was elevated in the dorsal skin of the two toad species treated with dry or wet conditions for 14 days. The increase in PRLR of dorsal skin in B. bankorensis was higher than that in B. melanostictus. This experimental result suggests that B. bankorensis secretes more mucus to reduce water evaporation from its thinner cuticle than B. melanostictus. The expression of PRLR protein was increased in the lung of B. bankorensis and decreased in the lung of B. melanostictus. Moreover, PRLR protein levels were increased in the kidneys in the two species toad, likely due to reduction in water lost through lung and urine. The two toad species were subjected to varying temperatures (25 degrees C, 15 degrees C and 10 degrees C) for 14 days. The lowest PRLR protein expression was observed at 10 degrees C. Comparison of the decreasing trend in PRLR protein levels demonstrated that the variation in B. bankorensis was significantly higher than that in B. melanostictus. Comparisons of variation in PRLR protein expression in the two species under different environments suggest that B. bankorensis is more adaptable to different environments than B. melanostictus.

TL;DR: The experiment involved acute and chronic tests on tadpoles of Bufo melanostictus Schneider,examining the mutagenic effects with respect to tadpole' micronuleus of red blood cells.
Abstract: Three kinds of synthetic detergent were tested for investigating their toxicological effects on aquatic biota.The experiment involved acute and chronic tests on tadpoles of Bufo melanostictus Schneider,examining the mutagenic effects with respect to tadpoles' micronuleus of red blood cells.
