Hurst was also a major initiator of the modern " genetical species concept " later known as the biological species concept.

The " Biological Species Concept ", proposed by Ernst Mayr, in 1942, emphasizes reproductive isolation as the basis of defining a species.

Under the biological species concept, a new species name " Rosa kordesii " was created for the tetraploid hybrid roses and their descendants.
14.
Naturalists introduced the biological species concept, the definition of species as a community that is reproductively isolated and occupies a distinctive ecological niche.
15.
:It's worth clarifying that creating species ( according to the biological species concept ) doesn't necessarily mean creating ecological niches or new morphological forms.
16.
The elevation of the subspecies to full species was tentatively rejected under the biological species concept at least, as there still seems significant gene flow.
17.
After articulating the biological species concept in 1942, Mayr played a central role in the species problem debate over what was the best species concept.
18.
If following the phylogenetic species concept, " androstictus " would be a separate species, but under the biological species concept it " only " qualifies as a subspecies.
19.
Mayr also formulated the biological species concept that defined a species as a group of interbreeding or potentially interbreeding populations that were reproductively isolated from all other populations.

L�ve also wrote papers about plant evolution from a more theoretical angle, e . g . the still cited " The biological species concept and its evolutionary structure ".
