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.

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.

Ernst Mayr and the origin of the species

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.

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.
