The species Mulinia lateralis (Say, 1822) is native to the western North Atlantic Ocean and was first documented in European coastal waters in 2017. Since then, M. lateralis was reported several times in large abundances in the coastal waters of the Netherlands, Belgium, and more scattered in Germany. While the introduction vector is still unclear, we assume that dispersal in the southern North Sea is driven by larval drift related to anti-clockwise residual tidal currents. To test this hypothesis and to document its current status in the central Wadden Sea, individuals were sampled systematically from intertidal flats along 10 transects ranging from the outer Ems River estuary in the west to the outer Elbe River estuary in the east (German North Sea coast) between February and May 2022. In total, 897 specimens of M. lateralis were sampled from 392 stations (mean abundance 2.3 ± 5.0 ind./m ² ). The shell length ranged between 4.0 and 23.6 mm. Regarding the increasing number of records of M. lateralis at multiple sites in Europe since 2017 and based on the data of this study, the species can be considered as established in the western and central Wadden Sea.

In the 2010s, the American dwarf surf clam Mulinia lateralis spread within four years, and the Pacific Manila clam Ruditapes philippinarum established in the northern Wadden Sea (Craeymeersch et al. 2019;Klunder et al. 2019;Lackschewitz et al. 2022). The former arrived with ballast water, and the latter initially by aquacultures in France and Britain. ...
For about a century, biodiversity in the tidal Wadden Sea (North Sea, European Atlantic) has increased by more than one hundred introduced species from overseas. Most originate from warmer waters and could facilitate the transformation of this coastal ecosystem to comply with climate warming. Some introduced species promote sediment stabilization and mud accretion. This could help tidal flats to keep up with sea level rise. Although some introduced species also entail negative effects, introductions have diversified lower food web levels, and may benefit foraging birds. So far, no resident populations have gone extinct because an introduced species had established. Rather than degrading the ecosystem, the establishment of introduced species seems to have raised the capacity to follow environmental change. We support increasing efforts against introductions to avoid risk. However, once species are integrated, the common condemnation attitude against “non-natives” or “aliens” ought to be reconsidered for tidal ecosystems of low biodiversity.

Mulinia lateralis is a native bivalve from the Western Atlantic Ocean, distributed from the Gulf of Saint Lawrence in Canada to Yucatan in Mexico. Based on morphological and genetic data of specimens collected in shrimp farms, in this work, we confirm the presence of M. lateralis in the Gulf of Guayaquil, Ecuador. Presence and its consequences of this invasive bivalve in the region is discussed.
... This species occupies a range of salinities and environments from estuaries to the shallow shelf (e.g. Cleveland et al., 2002;Craeymeersch et al., 2019) but is largely absent from cores in the Holocene estuarine environment. It therefore serves, when paired with lithostratigraphy, as a useful biostratigraphic indicator of upper (top 2 to 3 m) Pleistocene-age sediments. ...
The response of barrier islands to sea‐level rise is modulated by combinations of coastal processes, eco‐geomorphic feedbacks and structural controls, such as antecedent topography. Interactions among these drivers can lead to complex and non‐linear changes in island morphology and transitions between migrational, erosional or progradational states. This study seeks to constrain the morphological consequences of barrier islands migrating across complex antecedent topography in response to rising sea level. The stratigraphy of four barrier–backbarrier systems along the United States Mid‐Atlantic coast informs idealized geometries of diverse antecedent substrate. These outcomes are integrated into a cross‐shore morphodynamic model of barrier‐island migration to quantify the influence of this antecedent geology on barrier‐retreat behaviour. Additionally, this study explores the future response of specific barrier islands to various rates of sea‐level rise over multi‐decadal to millennial timescales. The results show that antecedent substrate slope plays a central role in barrier morphodynamic behaviour. In particular, migration across a subaqueous backbarrier ridge (for example, coastal barrier or dune deposits from earlier sea‐level highstands) can cause a succession of phase changes in a modern island. For example, the case studies illustrate that the steep slopes and decreased backbarrier accommodation associated with antecedent highs greater than 3 m in profile can greatly reduce island migration rates, effectively ‘pinning’ the island in place, even with sea‐level rise rates up to 6 mm yr−1. However, once the island migrates over the high, backbarrier accommodation increases, leading to enhanced overwash fluxes, more rapid landward migration, and possible drowning. Additionally, the results indicate that antecedent substrate may slow barrier‐island migration by providing sediment through both shoreface and inlet processes. The field and modelling insights from this study are presented as a conceptual model of the relative influence of various antecedent features on barrier‐island dynamics along sandy, siliciclastic coasts.
... The species was first recorded for the Netherlands, Germany (and Europe) in August 2017 in subtidal sediment samples taken in the Wadden Sea on both sides of the border between the Netherlands and Germany(Gittenberger et al., 2019;Klunder et al., 2019). About a month later it was additionally recorded in the south of the Netherlands off the coast of Zeeland(Craeymeersch et al., 2019). In 2018 populations were recorded at various localities along the Dutch coastline indicating that the species is establishing itself. ...
... The impact of invasive bivalves in their new habitats is difficult to predict as it depends on factors specific for the invaded ecosystem including settlement substrate types, local biodiversity and interactions with native communities (Padilla, 2010). Potentially detrimental effects of non-indigenous bivalves commonly range from competition for habitat and food resources with native species, to changes in biodiversity and impact on recruitment of other species (Cavaleiro et al., 2019;Craeymeersch et al., 2019;Guy et al., 2018;Troost, 2010). The effects of colonisation by invasive bivalves is not necessarily negative, as it reportedly contributed to biodiversity increase within degraded habitats and formation of complex three dimensional shelters from predators (Christianen et al., 2018). ...
Marine pollution favours the invasion and spreading of non-indigenous species in their new habitats. Comparative advantages of introduced and potentially invasive bivalves over their native counterparts might be reflected in better ability to cope with chemical stressors.
The objective of the present study was to investigate differences in the biochemical stress response to Cd and Cu between the flat oyster Ostrea edulis (Linnaeus, 1758), native to European coasts, and its non-indigenous congener, the Pacific oyster Crassostrea gigas (Thunberg, 1793), recently detected in the eastern Adriatic. Oysters were co-exposed in vivo to sub lethal concentrations of metals. The stress response of two oyster species was evaluated using biomarkers of neurotoxicity (acetylcholinesterase, AChE), detoxification (metallothioneins, MTs) and oxidative stress (glutathione S-transferase, GST; lipid peroxidation, LPO). Biomarkers related to oxidative stress response were the most informative and suggested comparably lower capability of the non-indigenous C. gigas for handling pro-oxidant conditions after Cu exposure.
Overall, the species-specific biomarker alterations displayed by oysters exposed simultaneously to the same experimental conditions represent the first evidence of differences between these two bivalves in the ability to overcome the chemically induced stress. The present research highlights the need for monitoring of biochemical features that might determine the behaviour of oysters in newly colonised habitats under environmental challenges foreseen in the upcoming years.
... Une première alternative pourrait être d´acquérir une des nouvelles plateformes de séquençage en temps réel (MinION -Oxford Nanopore Technologies).

L’extraction de l’arche noire (AN) Anadara tuberculosa est une des activités de pêche artisanale ancestrales des mangroves de la côte ouest d’Amérique Latine et son commerce soutient l’économie de milliers de familles. La conservation de ce bivalve emblématique des mangroves est menacée par la surexploitation des populations naturelles. Les mesures classiques de préservation de l’espèce se sont révélées inefficaces pour enrayer le déclin des populations. Ce travail de thèse propose la production de naissains en conditions artificielles d’écloserie, au Pérou, à des fins de repeuplement à l’issue d’un processus de « domestication » de ce bivalve sauvage. Nous avons 1) analysé la structure génétique des populations d’AN Sud-américaines, 2) évalué l’effet de différentes salinités sur la réponse physiologique de l’AN, 3) établi une stratégie de production de naissains SPF (Specific Pathogen Free) à partir de reproducteurs caractérisés génétiquement et provenant du Sanctuaire National des Mangroves de Tumbes. Ce travail constitue un modèle pour les futures stratégies de production et de repeuplement des stocks d’autres espèces vulnérables.
