The coalescent analysis in this study clearly identifies several large wild infestations in cool areas of Santa Cruz, Marin, and Sonoma counties as stepping stones to further introductions, providing the first solid evidence that large pathogen population size may be the most important factor leading to long distance spread of the disease.
Although 84% (46/55) of closed herds were already reported to be infected, maintaining a closed herd is an effective method to prevent further introduction of infected cows.
Moreover, prevention measures can be deployed to clean infested bivalve stock in order to avoid further introductions via aquaculture transfers, but the methods assayed are time-consuming and not free of environmental concerns (Denny 2008) and can even decrease the survival of the stock (Switzer et al. 2011).
To prevent further introductions of non-native ornamental fish, their sale must be more tightly regulated and their import, sale and ownership should be controlled through a permit system even if they are not yet declared as invasive.
To prevent the further introduction and spread of the virus, federal agencies restricted the importation of African rodents and restricted the domestic trade or movement of prairie dogs and certain other rodents.
In a move to quell the further introduction of such species, a federal district judge in California ruled in September 2006 that the EPA must begin regulating ballast water as a biological pollutant beginning in 2008.
The peer-reviewed papers presented in this issue by experts in their fields provide a further introduction to this information, most of which is, unfortunately, unknown to non-specialists.
If those who follow college football needed a further introduction to Dixon, he provided it here on a crisp evening before a nationwide television audience.
The modification of graphene on GC electrode leads to ca. 130 mV positive shift of the half-wave potential for the reduction of O2 to peroxide (HO2−), and further introduction of α-MnO2 nanowire catalyzes the disproportionation of HO2− produced effectively, which enables 4-electron reduction of O2 at low overpotential.
But the last thing we want is a further introduction to the boogeyman.
