Specific limitations include the small number of suitable publications encountered in our systematic review to guide the analysis.
For example, human action can increase propagule pressure and multiple introduction events make establishment more likely, because species have a higher chance to encounter suitable environmental conditions.
Together, these data suggest that the association between enhancers and promoters does not occur by random collision, but rather by a progressive scanning activity on the part of the enhancers, which then form a stable interaction with the first suitable element they encounter, i.e. the H19 promoter on the maternal chromosome and the Igf2 promoter on the paternal chromosome (27).
Results: There were 3601 encounters suitable for inclusion in the study.
Winter infection occurs when eggs excreted during unfavourable winters commence development in early spring, once suitable conditions are encountered, [2], [7], with infection typically evident in the host from July to October [8].
Incorporation of the mecA gene into the S. aureus genome is an unusual event, and requires both a delivery entity called the staphylococcal chromosome cassette (SCC), and a suitable but rarely encountered S. aureus genetic background that can tolerate the presence and expression of the mecA gene [ 45].
There is a common misconception that knowledge of a second language automatically confers the ability to translate out of and into it; translators have only to find one-to-one sets of verbal correspondence, consulting suitable dictionaries when they encounter unknown terms.
In these specific experimental conditions (arguably more realistic than those in experiments 1 and 2, because colonies in their natural environment should encounter several suitable nesting cavities of different qualities) gathering information prior to emigration therefore allowed to improve simultaneously speed, accuracy and group cohesion.
The larger the group, the more likely a person will encounter a suitable partner from his/her own ethnic group (Chiswick and Houseworth 2008; González-Ferrer 2006; Lieberson and Waters 1988; Lievens 1998).
The 'self-twining' (i.e. vine stems twining around each other) often occurs when vines grow beyond the height of a short support and then go up and down it, or when they fail to encounter a suitable support (Darwin 1875).
