“…For example, some invasive plants and filter-feeders can, in contrast to our predictions, have positive effects on biodiversity within trophic groups, e.g. through habitat formation , and invasive plants may have both positive and negative effects on higher trophic levels depending on type and pathway of the dominant interactions, for example, through third-or fourth-order consumption cascades (Eastwood et al 2007, Tronstad et al 2010). We did not test how invaders affect biodiversity of lower trophic levels because our literature search did not locate enough relevant primary studies.…”

Impacts of marine invaders on local biodiversity have not been analyzed across invasive species and invaded habitats. We conducted a meta-analysis of 56 field experiments published in 29 papers that examined the effects of marine invaders on local species richness, diversity, and/or evenness. We show that invaders, across studies, typically have negative effects on biodiversity within a trophic level but positive effects on biodiversity of higher trophic levels. For example, both plants and sessile filter-feeders had positive effects on richness and diversity of mobile consumers. The contrasting negative and positive effects on similar versus higher trophic levels are potentially manifested through community-wide antagonism (competition and consumption) versus facilitation (habitat and food provisioning) interactions, respectively. These relation ships extended to functional interactions, as sessile invaders had negative effects on the biodiversity of sessile communities (intra-functional interactions) but positive effects on the biodiversity of mobile communities (inter-functional interactions). Our analyses highlight the importance of pairing attributes of the invader and the impacted organisms to obtain simple predictions of how the diversity of entire communities may respond to species invasions on local scales. We also note that our analysis did not require information on co-evolutionary history but that such data, coupled with long-term large-scale mensurative data, are needed to gain a comprehensive predictive insight into invasion impact.

“…With only 16% of the worlds' marine eco regions free from NIS [7] , invasive species are challenging pre-and post-border bio security strategies, and threatening biodiversity and ecosystem services around the world [8,9] . However, invasions can also provide insight into community ecology dynamics [10] ; competitive interactions [11] and the resilience of native assemblages as NIS make their way into new ecosystems.…”

The mechanisms determining the strength of interactions between non-indigenous and native species in the invaded environment are of great interest to both ecologists and managers. On a Brazilian rocky shore, we experimentally measured predation intensity and prey preference of native predators on 2 exotic bivalves, Perna perna (which has been present for centuries) and Isognomon bicolor (introduced ca. 20 yr ago). Overall, predation was more intense on P. perna than on I. bicolor. Furthermore, P. perna was preyed upon more intensively by benthic crawling predators (whelks and, possibly, crabs), while larger, more mobile predators (fish and birds) were less selective. In addition, the larger, more abundant whelk Stramonita haemastoma selectively preyed on P. perna (for which handling time was shorter), while another whelk (Trachypollia nodulosa) preferred I. bicolor, although handling time was longer. Different shell morphologies of the 2 exotic prey and resource partitioning between the whelks may explain S. haemastoma and T. nodulosa feeding preferences, respectively. The thicker valves of I. bicolor compared to those of P. perna reduced the drilling or chipping efficiency by whelks. Although these prey species belong to the same functional group, differences in their shell characteristics could entail different mechanical constraints to predators. Therefore, native predators in the study system may prefer P. perna over I. bicolor because they are still adapting their foraging skills to handle the more recent invader, I. bicolor.

Prey preference of these predators can be influenced by many factors such as prey size, energy content, handling time, availability and the past experience of the predator (Pyke et al. 1977, Hughes & Dunkin 1984, Fairweather 1988, Etter 1996.Multiple species have invaded many hard substrate habitats over time; therefore, native species have been exposed to different invaders for different periods of time (e.g. Wasson et al. 2005, Eastwood et al. 2007. A number of complex novel interactions could be established subsequent to invasion due to the arrangement of new native-exotic or exotic-exotic contact (Dudas et al. 2005, Grosholz 2005, Matern & Brown 2005, MacDonald et al. 2007, Pratt & Grason 2007. On the one hand, non-indigenous species are expected to lose some or all native co-evolved enemies. This enemyrelease hypothesis is one of many possible explanations for the success of invasive species in a new area (Colautti et al. 2004). On the other hand, non-indigenous species could find new enemies in invaded areas that could control their populations (Parker & Hay 2005, Parker et al. 2006.Invasive species can have important...
