Such models would probably be suitable to investigate the most favorable situations in terms of gene flow (number of sampled and introduced individuals, frequency of introductions) between the three components of the metapopulation.
This framework considers the size and frequency of introductions (i.e. propagule pressure, P), ecosystem invasibility based on abiotic characteristics of the new environment (A), and biotic characteristics of an invasive species and its recipient community (B).
Therefore, it is interesting to observe the frequency of introduction of certain keys during program implementation in Croatia (Fig. 9).
The key parameters for defining a social control strategy are selection criteria of driver nodes, number of random new topics introduced, and frequency of introduction of new topics.
The considerations for the frequency of introduction of new topics are similar to those discussed for the number of new topics.
Their establishment success has not been shown to be higher than that of non-native species with smaller native ranges, meaning that this pattern is best explained by their increased frequency of introduction [69, 79].
For the long-term evolutionary impact of genome changes, the frequency of introduction of fragmented foreign DNA is not the key factor.
The frequency of introduction, diversity, and extent of these viruses in Laos suggests considerable movement of viruses into the country from surrounding territories (China and Vietnam, but not Cambodia) and within the country.
Hence, future models should incorporate how propagule pressure (size and frequency of introduction events) impacts genetic variation and how more realistic genetic architectures contribute to the evolutionary trajectory of invasive species.
Associations between particular host plant species and genetic structure of T. vaporariorum populations might alternatively reflect different introduction sources, as well as varying frequencies of repeated introductions [ 69].
