Pleistocene glacial advance and retreat has been proposed as an important
isolating mechanism in speciation within Picoides in general in western North America (Jackson and others 2002).

isolating mechanismThe
isolating mechanism of patent protection was operationalized as the total number of patents issued at the U.S.
Edison's lawsuits formed the basis for his competitive strategy and revealed regulatory legitimacy as his institutional
isolating mechanism. He initiated 33 suits on patent rights and copyrights at federal level between 1897 and 1905, whereas his competitors only initiated 13 federal-level suits (calculated from Musser's 1990 Appendix, pp.
Heterospecific pollen competition may be a common
isolating mechanism between hybridizing taxa.
The genetics of an
isolating mechanism between two sibling species of Drosophila.
This step is not yet realized in Guadeloupe, but such a case, where more marked differences in cercarial shedding timing act as a true
isolating mechanism, exists for two closely related species of schistosomes.
A reproductive
isolating mechanism is a composite character of two species considered together, and, except in cases of reinforcement, not the direct product of natural selection.
The degree of imitability is determined by the strength of
isolating mechanisms (Peteraf, 1993), which moves along a continuum from extremely strong to strong
isolating mechanisms in the domain of the RBV and RV, and gradually transitions into the domain of the PBV and SCPV with weak to nonexistent
isolating mechanisms.
His first rap was about reproductive
isolating mechanisms.
Service firms do not only have to develop unique service concepts but also protect these with the help of
isolating mechanisms. Rumelt calls such resource characteristics
isolating mechanisms that prevent an imitation by competitors and defines them as 'phenomena that limit the ex post equilibration of rents among individual firms' (Rumelt 1984: 567).
The instructor can ask them to analyze whether speciation has occurred in a particular story, and if so, what reproductive
isolating mechanisms have evolved; to distinguish Lamarckian versus Darwinian thinking in an author's writing (for example, by analyzing Spiderman's acquisition of powers from a spider bite); to observe how natural selection has led to adaptation and how drift has caused random changes in a given population.
