Detailed knowledge about the geographical pathways followed by propagules from their
source to the invading populations—referred to here as routes of invasion—provides …

There is mounting evidence that reduced genetic diversity in invasive populations is not as
commonplace as expected. Recent studies indicate that high propagule vectors, such as …

Invasive species are predicted to suffer from reductions in genetic diversity during founding
events, reducing adaptive potential. Integrating evidence from two literature reviews and two …

Biological invaders represent one of the primary threats to the maintenance of global
biodiversity, human health, and the success of human economic enterprises. The continuing …

Invasive freshwater fish represent a major threat to biodiversity. Here, we first demonstrate
the dramatic, human-mediated range expansion of the Trinidadian guppy (Poecilia …

The early stages of invasion involve demographic bottlenecks that may result in lower
genetic variation in introduced populations as compared to source population/s. Low genetic …

Animals are usually expected to avoid mating with relatives (kin avoidance) as incestuous
mating can lead to the expression of inbreeding depression. Yet, theoretical models predict …

The level of genetic diversity within populations of introduced species has received
increasing attention as an important factor influencing their survival and adaptive potential …

Aim Understanding the factors determining the transition from introduction of aliens to the
establishment of invasive populations is a critical issue of the study of biological invasions …

Chemical pollution from pharmaceuticals is increasingly recognised as a major threat to
aquatic communities. One compound of great concern is fluoxetine, which is one of the most …
