First, the DNA barcoding markers were found useful for interspecies identification but not suitable for intraspecies
As Table 1 shows, all typical uncertainty factors include an uncertainty component, and an adjustment component, except for the intraspecies
factor, where the adjustment component is replaced by a variability component.

This may be related to intraspecies
variations that are common in Monogenea or to an adaptive process (Kritsky et al., 1995).
In contrast, landscapes that are further along in succession or ecosystem development--i.e., landscapes with perennial vegetation and greater interspecies and intraspecies
diver-sity--are generally superior with respect to their numerous regulating, supporting, and provisioning ecosystem services relevant to agriculture, including nutrient and carbon retention and water uptake efficiency, regulation of pest populations, and net primary productivity.
This implies that intraspecies
transmission would be unlikely.
It is known that during the deferment period, the total number of tillers of the pasture decreases concomitantly with a decrease in vegetative tiller population density and elevation of those in the reproductive stage and dead ones (SANTOS et al., 2009b, 2010a), in response to the greater intraspecies
competition for light in the sward (DA SILVA; NASCIMENTO JUNIOR, 2007).
The existing investigations have no doubt assisted in fungal identification; however, some of the reports could not accurately categorize the fungi genera, particularly intraspecies

Examples of interspecies transmission of influenza viruses include: recent human and dog infections with the H5N1 subtype avian influenza virus ; canine infections with the H3N8 equine influenza virus in recent years [7, 8, 9]; transmission of a complete avian influenza virus (H3N2) to dogs and its successive intraspecies
transmission between dogs [6, 10, 11]; or experimental infection of dogs with H9N2 (avian influenza) .
The constant [U.sub.jj] (j = 1, 2) is the intraspecies
scattering length of the j-th hyperfine state and [U.sub.ij](i [not equal to] j) is the interspecies scattering length.
