In the past, most researchers used a single technique for identification of cryptic taxa, population structures, biosystematics, and phylogenetic studies. Our experience with the Anopheles quadrimaculatus complex shows the importance of using several methods on individual mosquitoes. This approach consists of analysis of the polytene chromosomes in ovarian nurse cells, gas chromatographic profi...

In modern biology, digitization of biosystematics publications is an important task. Extraction of taxonomic names from such documents is one of its major issues. This is because these names identify the various genera and species. This article reports on our experiences with learning techniques for this particular task. We say why established Named-Entity Recognition techniques are somewhat di...

Large numbers of virus species exist in the realm of nature, and are now classified into distinct sub-groups based on their biochemical and biological characteristics (Knipe et al., 2007). Viruses are unique in their genomic composition, nucleocapsid/ virion morphology, replication strategy, and/or target host. Even though viruses represent the smallest entity encoding a genetic program and are...

Genetic information is a valuable component of biosystematics, especially specimen identification through the use of species-specific DNA barcodes. Although many genomics applications have shifted to High-Throughput Sequencing (HTS) or Next-Generation Sequencing (NGS) technologies, sample identification (e.g., via DNA barcoding) is still most often done with Sanger sequencing. Here, we present ...
