| partitioning detectability components in populations subject to within-season temporary emigration using binomial mixture models. | detectability of individual animals is highly variable and nearly always < 1; imperfect detection must be accounted for to reliably estimate population sizes and trends. hierarchical models can simultaneously estimate abundance and effective detection probability, but there are several different mechanisms that cause variation in detectability. neglecting temporary emigration can lead to biased population estimates because availability and conditional detection probability are confounded. in thi ... | 2015 | 25775182 |
| the dynamic evolutionary history of genome size in north american woodland salamanders. | the genus plethodon is the most species-rich salamander genus in north america, and nearly half of its species face an uncertain future. it is also one of the most diverse families in terms of genome sizes, which range from 1c = 18.2 to 69.3 pg, or 5-20 times larger than the human genome. large genome size in salamanders results in part from accumulation of transposable elements and is associated with various developmental and physiological traits. however, genome sizes have been reported for on ... | 2017 | 28121461 |
| sequence capture and next-generation sequencing of ultraconserved elements in a large-genome salamander. | amidst the rapid advancement in next-generation sequencing (ngs) technology over the last few years, salamanders have been left behind. salamanders have enormous genomes-up to 40 times the size of the human genome-and this poses challenges to generating ngs data sets of quality and quantity similar to those of other vertebrates. however, optimization of laboratory protocols is time-consuming and often cost prohibitive, and continued omission of salamanders from novel phylogeographic research is ... | 2016 | 27862524 |
| thriving in the cold: glacial expansion and post-glacial contraction of a temperate terrestrial salamander (plethodon serratus). | the dynamic geologic history of the southeastern united states has played a major role in shaping the geographic distributions of amphibians in the region. in the phylogeographic literature, the predominant pattern of distribution shifts through time of temperate species is one of contraction during glacial maxima and persistence in refugia. however, the diverse biology and ecology of amphibian species suggest that a "one-size-fits-all" model may be inappropriate. nearly 10% of amphibian species ... | 2015 | 26132077 |
