The use of a short fragment of DNA sequence to distinguish between species -- DNA barcoding -- promises to streamline species identification, thereby enabling scientific research (e.g., studies of community ecology) and practical applications (e.g., monitoring the movement of biological materials across borders).
For the spring/summer 2011 season, streamlined sportswear, a recently endangered species, is back in style.
Steve White, the federation chairman, will tell the conference: "Neighbourhood policing is just one of the endangered species in the new, streamlined, barren policing landscape".
Diving beetles are so streamlined that the males of some species have sucker-like cups on the first pair of legs so that they can hold on to the smooth surface of the female during mating.
This species has a slender, streamlined body typical of the requiem sharks.
Like all penguin species, emperor penguins have streamlined bodies to minimize drag while swimming, and wings that are more like stiff, flat flippers.
By amplifying multiple DNA markers (the trnL intron, internal transcribed spacer region 1 [ITS1], and internal transcribed spacer region 2 [ITsimultaneouslyously, they streamlined the PCR process and increased species resolution for Poaceae, Asteraceae, Cyperaceae, and Rosaceae.
For each locus, we performed 100 bootstrap replicates, which permits error estimates to be generated on the species trees; this entire process was streamlined using a Perl-scripted pipeline developed by FTB and A. Narechania [ 51].
Clade 2, which consists exclusively of single-celled species with small cell size and streamlined genomes, such as marine Prochlorococcus and Synechococcus, are almost completely devoid of IS elements or DNA repeats of any kind.
