Abstract	Invasive species threaten the conservation of marine environments, and urgent management strategies are needed to prevent their introduction, establishment and spread. Specifically, marine invasive predators destabilize ecological interactions and alter community structure and function. However, most of the evidence showing the effect of these predators is restricted to a few species and regions, while for others the information remains scarce. This study experimentally evaluated the ecological effects of the sea slug Pleurobranchaea maculata, a recently introduced invasive predator, on the fouling communities of a cold‐temperate port in the South‐western Atlantic. The results show that increasing predation pressure reduces significantly the abundance of sea anemones, which are among the preferred prey items. This study reveals new evidence to help better understand the effects of P. maculata on the biological communities of a recently invaded region. Furthermore, it provides the first experimental evidence supporting the hypothesis that marine invasive predators can induce a significant decrease in the abundance of native species in benthic communities of cold‐temperate marine environments in the South‐western Atlantic.

Article: Predator–prey interactions as key drivers for the invasion success of a potentially neurotoxic sea slug

Abstract	Only a fraction of the species that are introduced succeed in the non-native environment, while others fail to survive, reproduce and/or disperse. Understanding the causes underlying each outcome is key to designing better early detection, prevention and management programs, and to deepen our knowledge of the invasion process. Here, we examine whether predator–prey interactions favor the invasion of a potentially neurotoxic mollusk in the South Western Atlantic (SWA). The grey side-gilled sea slug Pleurobranchaea maculata was recently detected in the SWA, where it has spread rapidly along the coast. In this work, we examine two hypotheses that may have driven the invasion success of P. maculata: (1) it has a high dietary plasticity, able to exploit resources in a variety of habitats within the invaded range and simultaneously (2) it lacks native predators that can control its abundance or spread. First, we identified the prey sources of P. maculata through experimental trials; then we compared its diet composition between different sites and seasons; and finally we experimentally assessed the effect of native potential predators. We found that diet composition is broad and varies in time and space, probably in relation to prey availability. Additionally, we observed that local predators do not recognize P. maculata as a prey. Probably, mechanisms underlying predator avoidance are related to the presence of chemical defenses that can be novel in the invaded environment. We propose that predator–prey interactions are key drivers favoring the establishment of non-native P. maculata via high levels of plasticity to exploit resources, the absence of biotic resistance and the increased availability of food associated with artificial substrates such as ports are probable mechanisms underlying the invasion success of this marine gastropod.

Abstract	Why do ecologists seem to underestimate the consequences of using bad taxonomy? Is it because the consequences of doing so have not been yet scrutinized well enough? Is it because these consequences are irrelevant? In this paper I examine and discuss these questions, focusing on the fact that because ecological works provide baseline information for many other biological disciplines, they play a key role in spreading and magnifying the abundance of a variety of conceptual and methodological errors. Although overlooked and underestimated, this cascade-like process originates from trivial taxonomical problems that affect hypotheses and ideas, but it soon shifts into a profound practical problem affecting our knowledge about nature, as well as the ecosystem structure and functioning and the efficiency of human health care programs. In order to improve the intercommunication among disciplines, I propose a set of specific requirements that peer reviewed journals should request from all authors, and I also advocate for urgent institutional and financial support directed at reinvigorating the formation of scientific collections that integrate taxonomy and ecology.

Article: Macropredators as shapers of invaded fouling communities in a cold temperate port

Abstract	Ports are vulnerable to biological invasions because of the high shipping exchange and the abundance and diversity of artificial structures. These artificial environments provide new habitats for fouling communities, commonly hosting a large number of exotic species. The colonization of artificial structures is influenced by large and small scale processes, such as differences in recruitment time (that may vary with season and availability of new substrates) or predation. In cold temperate regions, with a marked seasonality, not only the starting time of colonization may influence fouling community structure but also the community of macropredators associated. This study addressed the following question: What is the effect of macropredators on invaded fouling communities started at different time in a cold temperate port? To asses this, the following experimental treatments were assigned to three plates attached to a fiberglass structure: exclusion, open cage and open plate. At the beginning of each season, seven of these structures were tied to port pilings, each one containing the three experimental treatments. We found that fouling communities are shaped by macropredators, such as sea urchins, gastropods and crabs, and that their effect on community structure depends on the time or season in which the colonization started. Exotic ascidians were absent in open plates and open cages when macropredators were present, and species diversity was highest when these predators were excluded. Our results suggest that predation at high latitudes in cold temperate regions might be more important than what is predicted in recent works. Although our study is conclusive on specific points, it also exposes a need for further research disentangling the processes regulating the colonization of artificial fixed versus floating structures at different latitudes.

Abstract	Invasive species threaten native ecosystems worldwide. However, these species can interact positively with local communities, increasing their richness, or the abundance of some species. Many invasive species are capable of influencing the habitat itself, by ameliorating physical stress and facilitating the colonization and survival of other organisms. Barnacles are common engineer species that can change the physical structure of the environment, its complexity, and heterogeneity through their own structure. Balanus glandula is a native barnacle of the rocky shores of the west coast of North America. In Argentina, this invasive species not only colonizes rocky shores but it also has successfully colonized soft-bottom salt marshes, where hard substrata are a limiting resource. In these environments, barnacles form three-dimensional structures that increase the structural complexity of the invaded salt marshes. In this work, we compared the composition, density, richness, and diversity of the macroinvertebrate assemblages associated with habitats of different structural complexity in two Patagonian salt marshes where B. glandula is well established. Our results showed differences in the relative distribution and abundances of the invertebrate species between habitats of different complexities. Furthermore, the response of the communities to the changes in the structural complexity generated by B. glandula was different in the two marshes studied. This highlights the fact that B. glandula facilitates other invertebrates and affect community structure, mainly where the settlement substrata (Spartina vs. mussels) are not functionally similar to the barnacle. Thus, our work shows that the rocky shore B. glandula is currently a critical structuring component of the native invertebrate community of soft-bottom environments where this species was introduced along the coast of southern South America.

Abstract	Aim: Human activities have introduced numerous non-native species (NNS) worldwide. Understanding and predicting large-scale NNS establishment patterns remain fundamental scientific challenges. Here, we evaluate if NNS composition represents a proportional subset of the total species pool available to invade (i.e. total global biodiversity), or, conversely, certain taxa are disproportionately pre-disposed to establish in non-native areas. Location: Global. Time period: Present day. Major taxa studied: Global diversity. Methods: We compiled one of the most comprehensive global databases of NNS (36,822 established species) to determine if NNS diversity is a representative proportional subset of global biodiversity. Results: Our study revealed that, while NNS diversity mirrors global biodiversity to a certain extent, due to significant deviance from the null model it is not always a representative proportional subset of global biodiversity. The strength of global biodiversity as a predictor depended on the taxonomic scale, with successive lower taxonomic levels less predictive than the one above it. Consequently, on average, 58%, 42% and 28% of variability in NNS numbers were explained by global biodiversity for phylum, class and family respectively. Moreover, global biodiversity was a similarly strong explanatory variable for NNS diversity among regions, but not habitats (i.e. terrestrial, freshwater and marine), where it better predicted NNS diversity for terrestrial than for freshwater and marine habitats. Freshwater and marine habitats were also greatly understudied relative to invasions in the terrestrial habitats. Over-represented NNS relative to global biodiversity tended to be those intentionally introduced and/or ‘hitchhikers’ associated with deliberate introductions. Finally, randomness is likely an important factor in the establishment success of NNS. Main conclusions: Besides global biodiversity, other important explanatory variables for large-scale patterns of NNS diversity likely include propagule and ...

Article: Does low temperature prevent Spartina alterniflora from expanding toward the austral-most salt marshes

Abstract	Along the Atlantic coast of South America, the northern salt marshes (lower than 43°S) are dominated by Spartina species while the southern salt marshes (greater than 43°S) are dominated by Sarcocornia perennis. The most abundant Spartina species are Spartina densiflora which is present in most coastal marshes, and Spartina alterniflora that was never recorded above the ~42°25′S. It is not clear why S. alterniflora has not succeeded in the southern marshes, in which the low marsh zone remains as an extensive bared mud flat. We address the hypothesis that the absence of S. alterniflora in the south is driven by the cold temperatures inversely related with increasing latitudes along the East coast of Patagonia. To evaluate this hypothesis, we carried out an experiment in which we manipulated the temperature in combination with frost formation and photoperiod. We found that cold temperature produced a negative effect on S. alterniflora, and this effect seems accentuated by the frost but not by the reduction in the photoperiod. Our results support the hypothesis that the absence of S. alterniflora in the southernmost salt marshes of Patagonia is a consequence of the frost as an outcome of the co-occurrence of low temperature and high humidity. The importance of our results are discussed in the context of the global warming and how Spartina species enlarge their distributional range toward higher latitudes.
