“…It was surprising to find sixty fouling species on vessels in the Port of Recife in spite of the advice control of International Maritime Organization (IMO) and the very wide use of anti-fouling techniques, including paints. The predominance of arthropods in the fouling community sampled here (including crustaceans 47% of the species and insect chironomids and pycnogonids, both representing 2%) was also observed by Ray (2005), who observed respectively 27%, 20% and 6% for these taxa. Also Godwin (2003) observed that 35% of the hulls fouling species invaders to the Hawaiian isles were arthropods, against 16% and 13% of mollusks and polychaetes, respectively.…”

Ports of big coastal cities are exposed to exotic species as a consequence of shipping traffic. As the Port of Recife receives an annual average of 491 ships from other regions of Brazil and from all over the world, this work was aimed at knowing which marine animals were passively transported on such vessels hulls, in order to map and monitor new bioinvasions in the area. Thus, 32 vessels of several origins were investigated between November 2005 and March 2006, samples were taken and the macrofauna identified. Sixty species of associated animals were identified, consisting of 28 sessile species, particularly the Cirripedia Balanomorpha and Lepadomorpha as dominants, 8 sedentary animals, namely Mytillidae and Dreissenidae and 23 free-living species, particularly, Caprellidae, Gammaridae, Tanaidacea, Turbellaria, Nemertea and Polychaeta. The first occurrence of Conchoderma virgatum was recorded with exact location for the Brazilian littoral, and Conchoderma auritum, Amphibalanus subalbidus and Haliplanella lineata were recorded for the first time at the littoral of Pernambuco State. The invasion pathway was confirmed for Amphibalanus reticulatus and Mytilopsis leucophaeta, invader species of the estuarine area of Recife's city. Megabalanus coccopoma was considered as a risk invader species for the region.
Regiões portuárias das grandes cidades litorâneas estão sujeitas à recepção de espécies exóticas como conseqüência da movimentação dos navios. Como o Porto do Recife recebe uma média anual de 491 atracações de navios, provenientes de várias regiões do Brasil e do mundo, objetivou-se conhecer quais animais marinhos eram transportados passivamente nos cascos das embarcações para mapear e monitorar novas invasões biológicas na área. Assim, foram investigados 32 barcos de diversas origens, nos meses de novembro de 2005 a março de 2006, tendo a macrofauna sido amostrada e identificada. Foram encontradas 60 espécies de animais associados, sendo: 28 espécies incrustantes, destacando-se os Cirripedia Balanomorpha e Lepadomorpha, como dominantes, 8 sedentárias, destacando-se os Mytillidae e Dreissenidae e 23 vágeis, sendo os principais: Caprellidae, Gammaridae, Tanaidacea, Turbellaria, Nemertea e Polychaeta. A primeira citação de Conchoderma virgatum foi registrada com localização exata para o litoral brasileiro, e Conchoderma auritum, Amphibalanus subalbidus e Haliplanella lineata foram registradas pela primeira vez para o litoral do estado de Pernambuco. O meio de dispersão foi confirmado para Amphibalanus reticulatus e Mytilopsis leucophaeta, espécies invasoras da área estuarina da Cidade do Recife. Megabalanus coccopoma foi considerada como espécie em risco de invasão para a região

Coral reefs are iconic, threatened ecosystems that have been in existence for approximately 500 million years, yet their continued ecological persistence seems doubtful at present. Anthropogenic modification of chemical and physical atmospheric dynamics that cause coral death by bleaching and newly emergent diseases due to increased heat and irradiation, as well as decline in calcification caused by ocean acidification due to increased CO(2), are the most important large-scale threats. On more local scales, overfishing and destructive fisheries, coastal construction, nutrient enrichment, increased runoff and sedimentation, and the introduction of nonindigenous invasive species have caused phase shifts away from corals. Already approximately 20% of the world's reefs are lost and approximately 26% are under imminent threat. Conservation science of coral reefs is well advanced, but its practical application has often been lagging. Societal priorites, economic pressures, and legal/administrative systems of many countries are more prone to destroy rather than conserve coral-reef ecosystems. Nevertheless, many examples of successful conservation exist from the national level to community-enforced local action. When effectively managed, protected areas have contributed to regeneration of coral reefs and stocks of associated marine resources. Local communities often support coral-reef conservation in order to raise income potential associated with tourism and/or improved resource levels. Coral reefs create an annual income in S-Florida alone of over $4 billion. Thus, no conflict between development, societal welfare, and coral-reef conservation needs to exist. Despite growing threats, it is not too late for decisive action to protect and save these economically and ecologically high-value ecosystems. Conservation science plays a critical role in designing effective strategies.
