“…Malheureusement, aucun échantillon n'a été conservé. C. mutica a donc réussi dans le port du Havre une implantation pionnière pour la Manche et constitue, à ce jour, l'introduction la plus méridio-nale de l'espèce (Cook et al, 2007 ;Dewarumez et al, 2011).…”

Résumé -L'exploration des bassins des ports du -Aval (2010-Aval ( -2012, has led to a survey of 364 animal species, of which 36 are non native to the port of Le Havre ( studied since 1978); 268 species of which 13 are non native to the port of Antifer, and 98 animal and vegetal species, of which 12 are non native to the port of Rouen. Ancient and recent introductions are distinguished. The invasive character -or not -of every alien species, as well as the dynamics of the invasion, are discussed. Unlike Antifer and Rouen harbours, where the biological populations are respectively similar to those of the neighbouring coast or hydrographical system, the port of Le Havre plays the role of pioneer site for the settlement of many alien species. This role is favoured by the paralic character of this port.

“…However, S. muticum has been shown to provide a refuge for small fish and can be seen as a gathering point for plankton-seemingly making it a positive introduction to the Wadden Sea by increasing habitat value (Polte and Buschbaum 2008). How introductions and especially warm water species integrate into the ecosystem is the subject of our ongoing studies (Buschbaum 2005;Cook et al 2007;Kochmann et al 2008).…”

The Helgoland Roads time series is one of the richest temporal marine data sets available. Running since 1962, it documents changes for phytoplankton, salinity, Secchi disc depths and macronutrients. Uniquely, the data have been carefully quality controlled and linked to relevant meta-data, and the pelagic time series is further augmented by zooplankton, intertidal macroalgae, macrozoobenthos and bacterioplankton data. Data analyses have shown changes in hydrography and biota around Helgoland. In the late 1970s, water inflows from the south-west to the German Bight increased with a corresponding increase in flushing rates. Salinity and annual mean temperature have also increased since 1962 and the latter by an average of 1.67°C. This has influenced seasonal phytoplankton growth causing significant shifts in diatom densities and the numbers of large diatoms (e. g. Coscinodiscus wailesii). Changes in zooplankton diversity have included the appearance of the ctenophore Mnemiopsis leidyi. The macroalgal community also showed an increase in green algal and a decrease in brown algal species after 1959. Over 30 benthic macrofaunal species have been newly recorded at Helgoland over the last 20 years, with a distinct shift towards southern species. These detailed data provide the basis for long-term analyses of changes on many trophic levels at Helgoland Roads.

“…However, given the widespread distribution of non-native C. mutica, it is necessary to understand its ecology and biology in non-native habitats. Caprella mutica was first identified on the west coast of Scotland in 2000 (Willis et al 2004), and is now widely distributed on artificial substrates on both the east and west coasts of Scotland (Cook et al 2007). Artificial substrates (e.g.…”

Abstract. Information on the life history and population dynamics of non-native species is essential to understand the process of invasion and impacts on invaded ecosystems. The non-native marine caprellid amphipod Caprella mutica has successfully established populations on coastlines throughout the temperate northern hemisphere and in New Zealand in the southern hemisphere. The introduction mechanism has been surpassed and it is now important to understand its ecology and biology in non-native habitats. The seasonal population dynamics of C. mutica were investigated over 18 months at four sites with different levels of anthropogenic disturbance on the west coast of Scotland. Abundance of C. mutica fluctuated seasonally at all sites, peaking during June to October. The highest abundance recorded on a single mesh collector was 319 000 individuals m À2 in August 2004 at one of the fish farms. Both seasonal and site-specific factors influenced the population dynamics of C. mutica. Both males and females were significantly larger and more abundant at the fish farm sites. Individuals displayed reproductive characteristics at a smaller size at the fish farm sites, indicating earlier maturity. The results suggest that anthropogenic disturbance and artificial resource enhancement contribute to the global establishment success of non-native C. mutica.
