Apart from factors related to social organization, gene flow and recognition that predispose certain ants to become invasive pests, ecological factors are most likely to determine which introductions will ultimately give rise to invasive range expansions.
For some attempts to articulate conditions under which introduction and elimination rules do fix a meaning, see Belnap (1962), Hacking (1979, 296 8), Kremer (1988, 62 6), and Hodes (2004, 156 7).
For example, in vitro testing-machine studies should be followed by 2-year RSA studies in small cohorts in different institutions worldwide, followed by larger comparative studies, after which introduction to the market can be started (Malchau 2000)—with the latter also involving follow-up in national registries.
The present study assessed the extent to which the introduction of non-invasive prenatal diagnosis (NIPD) of Down's syndrome may undermine the process of making informed choices to undergo prenatal testing or screening for Down's syndrome by altering the quality and quantity of pre-test counselling.
There have also been complaints about the reluctance of lenders to pass on rate changes, and about the extent to which the introduction and management of QE have risked politicising the committee.
Future research should explore experiences of mixed-feeding intenders over time and the extent to which early introduction of mixed-feeding impacts on how long a woman successfully continues breastfeeding.
Population age and sex composition and all-cause mortality rates were calculated for each dataset and results were compared with the gold standard of the original 10-year data to determine the extent to which the introduction of errors affected the data's ability to represent the surveillance population.
The available data favor maintenance of SINV in a local endemic cycle but the extent to which new introductions of SINV may play a role remains a subject for further investigation.
We also included a random effect describing the biogeographic realm in which introductions occurred to control for clustering of introduction attempts within regions.
Our thermal denaturation studies on both wt and fluorinated protein aimed to investigate to which extent the introduction of (4R -FPro can enhance the stability of ubiquitin.
