The eco-evolutionary consequences of multiple introductions for colonizing individuals
… change-induced species range shifts, and reintroductions of rare species. Propagule pressure, which comprises the number of introduction events (propagule number) and the number of individuals per introduction event (propagule size), consistently correlates with a greater probability of …

Genetic factors affecting establishment during invasions : the introduction of the topmouth gudgeon (Pseudorasbora parva) and the rainbow trout (Oncorhynchus mykiss) in Europe
… European countries as a result of accidental introductions. Rainbow trout (Oncorhynchus mykiss) has been introduced from the United States for aquaculture and angling, however, despite numerous introductions, it has only been able to establish in few European waters. I used mitochondrial DNA …

Genomic surveillance of methicillin-resistant Staphylococcus aureus at local, regional and national levels
… of cases were positive for MRSA USA300, with multiple introductions and household transmissions identified. Five people were positive for ST2371, all of whom had a direct or indirect link to a substantial outbreak in an intensive care unit at Addenbrooke’s Hospital in 2011, thus confirming the …

Distribution and dispersal of the non-native caprellid amphipod, Caprella mutica Schurin 1935
… distribution of C. mutica is the result of multiple introduction pathways with stepping-stone events. A high genetic diversity was found in the native region but the source for the non-native populations could not be identified. Individuals from the east Pacific grouped together and were …
