“…Melita palmata , as a NIS highly associated to the habitat generated by another NIS (an invader ecosystem engineer), has a reduced potential to expand to novel habitats when habitat does not match with similar (or enough) resources to those provided by the invasive ecosystem engineer (edge limited, Fagan et al, 1999). Therefore, an invasive autogenic ecosystem engineer with high potential to modify the environment would not necessarily contribute to an invasional meltdown process (see Heiman et al., 2008), but rather constitute a primary substrate for other NIS, representing novel and easy‐to‐colonize habitats (Heiman & Micheli, 2010; Mangano, Ape, & Mirto, 2019; Ros, Lacerda, Vázquez‐Luis, Masunari, & Guerra‐García, 2016). The studied interactions are an example that might be relevant in ecosystem managing planning involving habitat restoration programs using artificial structure addition (e.g., Byers et al., 2006; Ros et al., 2016).…”

Effects of Ficopomatus enigmaticus ecosystem‐engineered habitat structure on population parameters of the amphipod Melita palmata: A NIS‐NIS interaction study

The variability of some population (demo) parameters of the gammarid amphipod Melita palmata was associated with contrasting habitat structures created by the non‐indigenous reef‐builder polychaete Ficopomatus enigmaticus in the Mar Chiquita coastal lagoon (37°40 S, 57°23 W, Argentina). Sampling of M. palmata was conducted biweekly during the reproductive period in F. enigmaticus reefs and sediment from reef‐free areas, accounting for the vertical distribution and the presence/absence of macroalgae. Males, females (non‐ovigerous and ovigerous), and juveniles are present in both reefs and sediment, but the abundance of M. palmata is several orders of magnitude higher in reefs. Reefs’ M. palmata population (demo) displays variations in: (a) abundance, (b) mean size, and (c) proportions of demographic categories. In reefs, females show a higher proportion of ovigerous specimens and a female‐biased sex ratio, contrasting the 1:1 ratio observed in sediment. Individuals are more abundant in the surface layer covered with macroalgae in reefs (small sizes) and macroalgae or valves in sediment. The association of M. palmata to F. enigmaticus reefs drives its permanency in the system, enhancing its reproductive potential via different reproductive traits and habitat use, with a reduced potential to spread to marginal areas.

“…Although the kelp populations did not differ in photosynthetic capacity, these results suggest a negative impact of the artificial structures on the host. Artificial substrates tend to provide suitable opportunities for novel, often invasive, organisms to settle (Mayer-Pinto et al 2015, Ros et al 2016). The same goes for newly introduced bacteria, which can potentially establish more easily on anthropogenic substrates where there may be a lower biological diversity (Amalfitano et al 2015).…”

Aquatic organisms rely on microbial symbionts for coping with various challenges they encounter during stress and for defending themselves against predators, pathogens and parasites. Microbial symbionts are also often indispensable for the host's development or life cycle completion. Many aquatic ecosystems are currently under pressure due to diverse human activities that have a profound impact on ecosystem functioning. These human activities are also ex pected to alter interactions between aquatic hosts and their associated microbes. This can directly impact the host's health and -given the importance and widespread occurrence of microbial symbiosis in aquatic systems -the ecosystem at large. In this review, we provide an overview of the importance of microbial symbionts for aquatic organisms, and we consider how the beneficial services provided by microbial symbionts can be affected by human activities. The scarcity of available studies that assess the functional consequences of human impacts on aquatic microbial symbioses shows that our knowledge on this topic is currently limited, making it difficult to draw general conclusions and predict future changes in microbial symbiont−host relationships in a changing world. To address this important knowledge gap, we provide an overview of ap proaches that can be used to assess the impact of human disturbances on the functioning of aquatic microbial symbioses.

“…First, most records of P. pusilla, both recent and old, come from this area (Ros and Guerra-García 2012). Second, while most records of P. pusilla from putative introduced areas are located in artificial habitats (such as those from India, Europe, Australia, Hawaii, and Pacific Mexico and Panama), in the putative native region P. pusilla is also common in natural habitats (Ros et al 2016b). Third, the biogeographic distribution of species of Paracaprella (Fig.…”

Paracaprellapusilla Mayer, 1890 is a tropical caprellid species recently introduced to the Eastern Atlantic coast of the Iberian Peninsula and the Mediterranean Sea. In this study, we used direct sequencing of mitochondrial (COI and 16S) and nuclear (28S and ITS) genes to compare genetic differences in presumed native and introduced populations in order to infer its introduction pattern and to shed light on the native range of this species. The temporal pattern of genetic diversity at the westernmost limit of the geographic range of P.pusilla in Europe (the Atlantic coast of southern Spain) over an eight-year period was also investigated. Our results confirm P.pusilla as a neocosmopolitan species and suggest that the species is native to the Atlantic coast of Central and South America. Paracaprellapusilla seems to have been introduced into European waters from multiple introduction pathways and source populations, which are likely to include populations from coastal waters of Brazil. Multiple introduction pathways may have been involved, with the most important being commercial shipping through the Strait of Gibraltar. While this tropical species appears to be expanding in the Mediterranean, populations from the westernmost limit of its geographic range in Europe showed a temporal instability. This study constitutes the first molecular approach focused on this species, but it is also the first study of temporal change in genetic diversity of any introduced marine amphipod. Additional intensive sampling of this species, including both native and non-native populations, and detailed temporal studies are still necessary to properly understand how genetic diversity influences the introduction and survival of P.pusilla in invaded areas.
