Once drawn, species could not be drawn again for that particular simulated ensemble or functional group.
They demonstrated that this community could be accurately modelled by drawing species at random from a defined pool of British breeding woodland bird species.
We assessed the data for evidence of LBA which would manifest itself in the data by drawing species with a greater number of mutations in the gene of interest together erroneously on the phylogenetic tree.
The issue is, I think, mostly empirical (what do we do in case of phylogenetic conflict between genes?) and quantitative (up to which level of conflict should we keep drawing "species" trees?).
In order to maintain this popularity – and income – they have to cram in as many charismatic, big-draw species as possible into a limited space.
These virulence studies along with findings that G. vaginalis is the only species that can be detected in the vast majority of cases of BV and increasing reports of extravaginal infections in which it is the only species isolated, such as bacteremia and osteomyelitis, have drawn this species back into the spotlight and resurrected the notion of its pathogenic potential [ 13- 16].
Other parts of the world, like the South Pacific, may draw more species, but the shells are not nearly as easy to find.
Likewise, the implication that this central event spurred Audubon on his quest to draw every species of bird in America (just as it led Gautreaux to give up the serious study of anatomy) falls short.
And so with each near- microscopic paillon she positions and seals in its glass tomb, Porchet draws the species that much closer to extinction.
No matter how finely the distinctions are drawn, the species (or "varieties") that replace one another in time, space, and even on nearby islands in an archipelago, show "constant" differences, one from another.
