The invasive Asian benthic foraminifera Trochammina hadai Uchio, 1962: identification of a new local in Normandy (France) and a discussion on its putative introduction pathways
The invasive benthic foraminifera Trochammina hadai has been found for the first time in Europe along the coast of Normandy. Its native range of distribution is in Asia (Japan and Korea), and it has also been introduced along the coasts of western North America, Brazil and Australia. Morphological and molecular assessments confirm that specimens found in Le Havre and Caen-Ouistreham harbors belong to the Asiatic type. Like in Asia, T. hadai was found in transitional waters with muddy sediments. It exhibited high relative abundances (up to about 40%) confirming that T. hadai is a highly competitive species. In the present study, it was nearly absent from natural transitional waters and very abundant in heavily modified habitats like harbors, suggesting that ballast waters may likely be the vector of introduction. It was not recorded farther north along the coast of the Hauts-de-France. It is further hypothesized that the finding of a few specimens outside the harbor may facilitate the expansion of T. hadai in the English Channel by means of propagules dispersion.
期刊介绍:
Aquatic Invasions is an open access, peer-reviewed international journal focusing on academic research of biological invasions in both inland and coastal water ecosystems from around the world.
It was established in 2006 as initiative of the International Society of Limnology (SIL) Working Group on Aquatic Invasive Species (WGAIS) with start-up funding from the European Commission Sixth Framework Programme for Research and Technological Development Integrated Project ALARM.
Aquatic Invasions is an official journal of International Association for Open Knowledge on Invasive Alien Species (INVASIVESNET).
Aquatic Invasions provides a forum for professionals involved in research of aquatic non-native species, including a focus on the following:
• Patterns of non-native species dispersal, including range extensions with global change
• Trends in new introductions and establishment of non-native species
• Population dynamics of non-native species
• Ecological and evolutionary impacts of non-native species
• Behaviour of invasive and associated native species in invaded areas
• Prediction of new invasions
• Advances in non-native species identification and taxonomy
