| tetrodotoxin in asian newts (salamandridae). | tetrodotoxin (ttx) and its analogues occur in a wide range of marine animals but also in terrestrial vertebrates such as frogs, toads and newts. despite numerous studies on ttx in new world newts (notophthalmus viridescens, taricha spp.), few data only exist for asian newts. methanolic extracts of newts from china (cynops orientalis, pachytriton labiatus, paramesotriton chinensis), vietnam (paramesotriton deloustali, p. guangxiensis), and laos (laotriton laoensis) were analyzed by liquid-chromat ... | 2017 | 28528177 |
| mitochondrial genome of pachytriton feii (urodela: salamandridae). | in this paper, the complete mitochondrial genome of pachytriton feii is sequenced and reported for the first time. in our result, the complete mitochondrial genome of p. feii is 16 293 bp in length. similar to the typical mtdna of vertebrates, it contained 37 genes (13 protein-coding genes, 2 rrna genes, and 22 trna genes) and 1 non-coding region (d-loop). all the genes in p. feii were distributed on the h-strand, except for the nd6 subunit gene and eight trna genes which were encoded on the l-s ... | 2017 | 26714231 |
| predicting environmental suitability for a rare and threatened species (lao newt, laotriton laoensis) using validated species distribution models. | the lao newt (laotriton laoensis) is a recently described species currently known only from northern laos. little is known about the species, but it is threatened as a result of overharvesting. we integrated field survey results with climate and altitude data to predict the geographic distribution of this species using the niche modeling program maxent, and we validated these predictions by using interviews with local residents to confirm model predictions of presence and absence. the results of ... | 2013 | 23555808 |
