“…Scinaia acuta was originally described for Australia (Setchell 1914), later for the Canaries (Reyes et al 1993) and now for the Azores, a distribution pattern that suggests its introduction to these Macaronesian archipelagos. There are twelve species of marine algae classiWed as non-indigenous species for the Azores (Cardigos et al 2006). Little is known on marine species introductions and invasions to this archipelago, but its high potential for introductions has been widely discussed, considering the increase of the transatlantic leisure boat-traYc stopping at these islands.…”

A re-evaluation of Scinaia (Nemaliales, Rhodophyta) in the Azores

2010

The genus Scinaia in the Azores is re-evaluated based on historical and recent collections. A combination of morphological and anatomical diagnostic characters was used for species segregation, and a key for Azorean species determination is presented. Anatomical information associated to the hair development is described for the Wrst time for the genus. The occurrence of S. furcellata and S. interrupta is conWrmed for the archipelago. The presence of S. acuta is reported for the Wrst time in the Azores, representing a spread from Australia to the N-Atlantic and speciWcally into the Macaronesian region. Its occurrence in the archipelago and the Canaries is discussed as a possible introduction.

“…Given the islands' location and age, their colonization by marine organisms is believed to occur mainly through oceanic currents. Little is known on anthropogenic introductions of marine species in the Azores as only a single study was published on Azorean marine aliens (Cardigos et al 2006). Nevertheless, the islands are exposed to a high risk of species introductions, considering the increase in transatlantic leisure boat traffic and commercial maritime traffic stopping at the islands over the last decade, not to mention potential naturalizations since the fifteenth century when the discovery of the archipelago resulted in an obligatory stop over for most ships crossing the north Atlantic or on their way to Africa and India.…”

New alien barnacles in the Azores and some remarks on the invasive potential of Balanidae

2011

Global homogenization of biota is underway through worldwide introduction and establishment of nonindigenous (exotic) species. Organisms fouling ship hulls are continually in transit and can affect communities through biodiversity loss and serious damage to economy and public health. In the Azores, for the first time, underwater alien species prospection was conducted in marinas and recreational harbours, at São Miguel Island. Populations of three locally previously unknown barnacle species were found: Amphibalanus amphitrite, Amphibalanus eburneus and Perforatus perforatus. These species account for the more than 50% of alien barnacles worldwide that belong to Balanidae family. Hence, some considerations about morphology and life cycle of this family are advanced, discussed and related to their invasive potential.

“…In the last decade, several marine invertebrates have been reported as being introduced recently into the archipelago [14]: Amathia verticillata (Delle Chiaje, 1822) (Gymnolaemata) [3]; Perforatus perforatus (Bruguière, 1789) (Thecostraca) [84]; Schizoporella errata (Waters, 1878) (Gymnolaemata) [57]; Phorcus sauciatus (Koch, 1845) (Gastropoda) [5]. It has been shown, moreover, that the non-indigenous marine algal flora of these remote islands is double the number known at a global scale (6 vs. 3 % non-indigenous macroalgae) [56].…”

Some Bryozoa species recently introduced into the Azores: reproductive strategies as a proxy for further spread

et al. 2016

In the marine environment, control of invasive species' population levels, that is, keeping them at an abundance level which is below a density-dependent adverse effect, may be the most attainable goal for the management of introduced bryozoans. An improved understanding of reproductive strategies and life history traits is key in order to understand the spreading potential. The assessment of the magnitude and temporal dynamics of propagule pressure from the reproducing population important for the success of control actions and needs is to be determined prior to any field intervention. The reproductive cycle of three fouling bryozoans (Bugula neritina, Tricellaria inopinata and Virididentula dentata) in the waters of the Azores Archipelago was assessed. The study revealed that although the release of larvae can occur throughout the entire year, its intensity and developmental and the attachment success of the ancestrula are not even throughout the year and that each species' reproductive development needs to be determine independently. In the light of these findings, it is possible to determine the best time to apply field actions aimed at controlling invasive population's density levels, optimizing the always scarce financial resources for marine management.
