| evolutionary relationships and reproductive isolating mechanisms in the rice frog (fejervarya limnocharis) species complex from sri lanka, thailand, taiwan and japan, inferred from mtdna gene sequences, allozymes, and crossing experiments. | the rice frog (fejervarya limnocharis) species complex is widely distributed, from india to japan, and most prevalently in southeast asia. conspicuous morphological variation has been reported for this species complex throughout its distribution range. in the present study, we used mtdna gene sequence and allozyme analyses to infer evolutionary affinities within this species complex using eight populations (sri lanka; bangkok and ranong in thailand; taiwan; and hiroshima, okinawa, ishigaki and i ... | 2007 | 17867856 |
| prevalence of malformed frogs in kaoping and tungkang river basins of southern taiwan. | in this study we found many amphibians with bizarre appearances, known as malformations in pingtung county southern taiwan. for this investigation we collected frogs inhabiting the kaoping and tungkang river watersheds between february 2006 and june 2007. among the total number of 10,909 normal frogs (i.e., anurans) collected during the investigation period, the indian rice frogs (rana limnocharis) account for the greatest number next is the chinese bullfrog (rana rugulosa). of all the 244 captu ... | 2010 | 21047008 |
| impacts of the herbicide butachlor on the larvae of a paddy field breeding frog (fejervarya limnocharis) in subtropical taiwan. | butachlor is the most commonly used herbicide on paddy fields in taiwan and throughout southeast asia. since paddy fields provide habitat for pond breeding amphibians, we examined growth, development, time to metamorphosis, and survival of alpine cricket frog tadpoles (fejervarya limnocharis) exposed to environmentally realistic concentrations of butachlor. we documented negative impacts of butachlor on survival, development, and time to metamorphosis, but not on tadpole growth. the 96 h lc(50) ... | 2011 | 21210217 |
| alterations of biochemical parameters in malformed indian rice frogs, rana limnocharis from southern taiwan. | the purpose of this study is to investigate the factors that cause malformed frogs in upstream kaoping river (kp site) and tungkang river (t site) of southern taiwan. in this experiment, the activities of monooxygenase (mo), glutathione-s-transferase (gst), acetylcholinesterase (ache) as well as the concentration of vitellogenin (vg) in the liver were measured. results show that activities of mo, gst and ache, and vg levels in normal frogs (male/female) were 0.09 +/- 0.02/0.09+/-0.01 deltaa min( ... | 2011 | 22471220 |
| effects of salinity on the survival, growth, development, and metamorphosis of fejervarya limnocharis tadpoles living in brackish water. | we studied salinity tolerance and the effects of salinity on growth, development, and metamorphosis in fejervarya limnocharis tadpoles living in brackish water. specifically, we examined whether tadpoles exhibit adaptive plasticity in development when exposed to different salinities. tadpoles collected on green and orchid islands off southeastern taiwan were assigned to salinities of 0, 3, 5, 7, 9, 11, and 13 parts per thousand (ppt). the daily survival, weekly growth, and development of tadpole ... | 2009 | 19663642 |
