Post-infection A/Vietnam/1194/2004 (clade 1) ferret serum (infected with a low pathogenic reverse genetics virus produced with hemagglutinin and neuraminidase gene segments of A/Vietnam/1194/2004 and the remaining 6 gene segments of A/Puerto Rico/8/34) was tested by hemagglutination-inhibition (HI) for cross-reactivity with viruses belonging to clade 0 (A/Hong Kong/156/1997), 2.
The most prevalent clades are B (found mainly in North America and Europe), A and D (found mainly in Africa), and C (found mainly in Africa and Asia).
Lastreopsis (corresponding to the clade Lastreopsis s.
individuals with complete gene sampling only) produced similar topologies indicating with high support that the core clade of obligate army-ant-followers (henceforth, the complex) contains five well-supported clades within it (Figs.
The Nearctic clade ranges widely over the western and central USA and northern and central Mexico, with the MTZ as the southern boundary (Figs.
2 (in the BEAST package), where 20 % of the trees were discarded as the bum-in, and a maximum clade credibility tree was estimated from the remaining 32,000 trees.
The 29 haplotypes observed in the Laotian native fowls were clustered into five clades (Figure 1).
Northern Clade and Southern Clade 1 exhibit identical radula morphology, with 2-3 vestigial outer teeth (Figure 3A-D).
In his book The Semiaquatic Bugs, Andersen (1982) established the phylogeny of Gerromorpha, and diagnosed the clade on presence of three pairs of cephalic trichobothria inserted in deep cuticular pits; quadrangular mandibular levers; pretarsi with one dorsal and one ventral arolium, and the female genital tract with a gynatrial complex, including a long tubular spermatheca and a secondary fecundation canal.
Biologists have long assumed that rapid speciation occurred when a clade first developed a new physical trait or mechanism and had begun its own genetic branch.
