Genetic admixture of divergent intraspecific lineages is increasingly suspected to have an
important role in the success of colonising populations. However, admixture is not a …

During the past three decades, coastal marine waters have become among the most
invaded habitats globally. Ascidians are among the most notorious invaders in these …

Biological invasions have become a defining feature of marine Mediterranean ecosystems
with significant impacts on biodiversity, ecosystem services, and human health. We …

Aim The global sprawl of marine hard infrastructure (eg breakwaters, sea walls and jetties)
can extensively modify coastal seascapes, but the knowledge of such impacts remains …

Over the last 15 years studies on invasion genetics have provided important insights to
unravel cryptic diversity, track the origin of colonizers and reveal pathways of introductions …

Globally, ascidians are a significant contributor to benthic marine fouling communities, but
have remained poorly studied in this context. In some cases, such as in shellfish and finfish …

Humans have built ports on all the coasts of the world, allowing people to travel, exploit the
sea, and develop trade. The proliferation of these artificial habitats and the associated …

A main goal of population geneticists is to study patterns of gene flow to gain a better
understanding of the population structure in a given organism. To date most efforts have …

The invasion of natural ecosystems by non-indigenous species (NIS) is one of the greatest
threats to native biodiversity (Wilcove et al. 1998, Butchart et al. 2010). Although only a small …

The relationship between shipping and invasion success in marine waters has rarely been
demonstrated empirically. In commercial ports, greater shipping activity is expected to …
