In any case, extirpation of the primary lesion appeared to halt further skin lesions.
Selective logging may convert a common forest tree species into a rare one, and cause local extirpation or even extinction of rare and high-value species (Fearnside 1997; Laurance 1999).
Likewise, humans have caused the extirpation of other large carnivores across continents, including North America.
Alternatively, but not mutually excusive, the continental slope might have been exposed during low sea level episodes (as a result of the narrow shelf), causing local extirpation of Cathorops.
In 1825, a storm reconnected the Limfjord and the North Sea, and the increased salinity caused immediate extirpation of most whitefish.
This seems improbable if the British Virgin Islands had been occupied by the Puerto Rican population of bananaquits, and suggests that a catastrophic event might have caused the extirpation of populations in the northern LA and the British Virgin Islands.
Note that these losses pertain to losses of harvested biomass, not of all prey organisms, allowing for the possibility that green crab might eliminate harvestable biomass without causing local extirpation (see Discussion).
Over longer time scales, changes in precipitation regimes will alter relative abundances, allow new species to colonize, and cause the local extirpation of current members of the community [8].
Large-scale conversion of the original tallgrass prairie to agriculture is believed to be the leading cause of local extirpation and widespread reductions in the numbers of P. praeclara (Sheviak and Bowles, 1986).
The idea of a "Jewish Christianity" being written out of history by perfidious Pauline Christians must be set against the real extirpation caused by the Roman destruction of the Temple in the year 70CE, which had profound ramifications for both Judaism and early Christianity.
