The hypothesis that the lungless salamander Desmognathus fuscus responds actively to hypoxia was tested. Patterns of buccal movements [apneic period duration, the duration (min h(-)(1)) of buccal pumping and buccal pumping frequency], heart rate and metabolic rate (rates of oxygen uptake and carbon dioxide output) were determined during a control period (21 % oxygen), a hypoxic period (2, 5, 6....

We herein present clinical findings of an Iriomote cat with Hepatozoon felis parasitemia. A male Iriomote cat was captured for ecological analyses three times from January 2010 to January 2011. Although this cat did not show any hematological abnormalities at the time of the first capture, H. felis parasitemia and increased serum creatine kinase levels were detected at the second and third capt...

Sex differentiation of gonads in amphibians is believed to be controlled genetically, but altered epigenetically or environmentally. When larvae of the salamander Hynobius retardatus were reared at defined temperatures from hatching to metamorphic stages, a high temperature (28 degrees C) induced exclusively female gonads (ovaries), whereas intermediate (20 and 23 degrees C) or lower (16 degree...

Pacific yellowtail emperor, Lethrinus atkinsoni Seale, 1910, is one of the most targeted reef fish species in Southern Sulawesi, Indonesia. Therefore, assessing its stock important to understand condition population, providing valuable inputs for sustainable fisheries management area. Here we assess L. Indonesia, using length-based spawning potential ratio model. A total 4,887 individuals were ...

Development of effective conservation and management strategies requires assessments ecosystem biodiversity status, especially in understudied hotspots global fish diversity. Coral reefs are important habitats for fishes, with known globally. We present the first data on molecular diversity fishes Mischief Reef, largest atoll Nansha Islands. Partial sequences (650 bp) mitochondrial COI gene (Cy...

A new species of the Scinax ruber clade is described from Chapada dos Veadeiros region, Central Brazil. The new species is diagnosed by having SVL 21.9-27.7 mm in males and 26.7-31.7 mm in females; snout acuminate in dorsal view and rounded in profile; medium-sized tympanum; vocal sac single, median, subgular, that does not reach the pectoral region; iris iridescent yellow, with some thin, dark...

Temporary ponds where many amphibians breed experience a gradual desiccation that leads to growing larval densities, which can reduce tadpole survival rates and increase cannibalistic interactions among carnivorous salamander larvae. Concentrations of many agrochemicals, including nitrogenous fertilizers, can also increase as the water volume decreases. We analyzed the effects of ammonium nitra...
