methane emission from fields with differences in nitrogen fertilizers and rice varieties in taiwan paddy soils. | flooded rice fields are one of the major biogenic methane sources. in this study, methane emission rates were measured after transplanting in paddy fields with application of two kinds of nitrogen fertilizers (ammonium sulfate, nh4+-n and potassium nitrate, no3(-)-n) and with two kinds of rice varieties (japonica and indica). the experiment was conducted in fields located at tainan district agricultural improvement station in chia-yi county (23 degrees 25'08"n, 120 degrees 16'26"e) of southern t ... | 2003 | 12653295 |
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 |
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 |
