Sentence examples for operational species from inspiring English sources

d) Note that operational species concepts would be secondary to this primary concept        .

Rather than posing a problem, multiple operational species concepts are a natural outcome of the development of new technologies and the impact of the results those technologies provide.

These operational species concepts should be viewed not as competing definitions that falsely inflate the so-called species problem, but as compatible concepts consistent with an ontological understanding of species that has been in effect for decades.

A basic assumption of many species concepts [e.g. [ 9- 13]] and operational species delimitation methods [ 14] is that individuals of one species share common ancestry to the exclusion of members of other species.

The metapopulation lineage species definition leads to operational species delimitation approaches that recognize sets of populations that freely exchange genes in nature but have no or very restricted gene exchange with other sets of populations [ 18].

After all, the inability to breed successfully with other groups has long been an operational definition of species.

Although many concepts were promoted as superior to the rest, their operational approaches to species recognition limited the scope of each.

In both cases, there is perhaps a good case for monism regarding the concept, with pluralism welcomed at the operational level (for species — many kinds of evidence for hypotheses; for biodiversity — many kinds of protection strategies and many kinds of values of society to be traded-off).

For operational genes, 11 species show this pattern (P < 0.03).

MSHR1132, and the CC75 lineage in general, presents a very interesting and challenging case study in bacterial systematics, particularly given the recent interest in identifying operational and conceptual species definitions (Achtman and Wagner 2008).

Using a threshold of 1 1.3% for the operational identification of species based on 16S rRNA genes (Thompson et al. 2005; Pei et al. 2010), 137 genomes demonstrated an intragenomic diversity equal to or higher than the operational threshold, revealing a borderline diversity (between 1% and 1.3%) in 57 genomes and ≥1.3% in 80 genomes.
