We have investigated the distribution of several recently inserted Alu family members within representatives of diverse human groups. Human population studies using 65 unrelated human DNA samples, as well as a familial study to test inheritance, showed that individual Alu family members could be divided into three groups. The first group consisted of(More)
Molecular and biochemical genetic analyses have revealed that many marine invertebrate taxa, including some well-studied and presumably cosmopolitan species, are actually complexes of sibling species. When morphological differences are slight and estimated divergence times are old, data suggest either unusually high rates of sequence evolution or long-term(More)
One of our goals for the echinoderm tree of life project ( http://echinotol.org ) is to identify orthologs suitable for phylogenetic analysis from next-generation transcriptome data. The current dataset is the largest assembled for echinoderm phylogeny and transcriptomics. We used RNA-Seq to profile adult tissues from 42 echinoderm specimens from 24 orders(More)
Given a collection of strings, goal of the approximate string matching is to efficiently find the strings in the collection that are similar to a query string. In this paper, we focus on edit distance as measure to quantify the similarity between two strings. Existing <i>q</i>-gram based methods to address this problem use inverted indexes to index the(More)
Geological events in the latter Cenozoic have influenced the distribution, abundance and genetic structure of tree populations in temperate and tropical North America. The biogeographical history of temperate vegetation that spans large ranges of latitude is complex, involving multiple latitudinal shifts that might have occurred via different migration(More)
Allozyme polymorphisms have been used frequently in laboratory mating experiments to study patterns of sperm utilization in multiply mated females. In some instances, due either to chance or to design, there is a diagnostic difference between male genotypes that allows unambiguous assignment of paternity. In other instances, there is some overlap in allelic(More)
