| composition and structure of helminth communities of the salamanders, aneides lugubris, batrachoseps nigriventris, ensatina eschscholtzii (plethodontidae), and taricha torosa (salamandridae) from california. | component helminth communities of aneides lugubris (n=31), batrachoseps nigriventris (n=63), ensatina eschscholtzii (n=30), and taricha torosa (n=68) from california were determined. the compound helminth community consisted of 1 species of cestode, bitegmen gerrhonoti and 6 species of nematodes, batracholandros salamandrae, cosmocercoides variabilis, falcaustra pretiosa, megalobatrachonema gigantica, oswaldocruzia pipiens, and rhabdias joaquinensis. the least diverse infracommunities were assoc ... | 1998 | 9576495 |
| the complete mitochondrial genome of batrachoseps nigriventris (caudata: plethodontidae). | batrachoseps nigriventris was classified in order caudata, family plethodontidae. in this study, we obtained the complete mitochondrial genome sequence of b. nigriventris, which was 17 403 bp in length. with a base composition of 33.5%a, 30.9%t, 21.4%c, and 14.2%g, this genome contained 13 protein-coding genes (pcgs), 23 transfer rna genes (trna), 2 ribosomal rna genes (rrna), and 1 control region (d-loop) . phylogenetic analysis was performed using protein-coding genes cox1, combined with other ... | 2017 | 26710719 |
| slender salamanders (genus batrachoseps) reveal southern california to be a center for the diversification, persistence, and introduction of salamander lineages. | the southern california biodiversity hotspot has had a complex geological history, with both plate tectonic forces and sea level changes repeatedly reconfiguring the region, and likely driving both lineage splittings and extinctions. here we investigate patterns of genetic divergence in two species of slender salamanders (plethodontidae: batrachoseps) in this region. the complex geological history in combination with several organismal traits led us to predict that these species harbor multiple ... | 2020 | 32864205 |
