Seagrasses of Piauí, Brazil: A floristic treatment

et al. 2018

View full text Add to dashboard Cite

Marine angiosperms are submerged marine plants with a wide global distribution, occurring in temperate and tropical areas where they form meadows that harbour algae and marine fauna that are important for the functioning of the coastal ecosystem. This study is a floristic survey of the seagrasses occurring in the coastal region of the State of Piauí, Brazil. Five species were recorded for two genera in two families; for the Cymodoceaceae: Halodule wrightii Asch., Halodule beaudettei (Hartog) Hartog and Halodule emarginata Hartog; and for the Hydrocharitaceae: Halophila decipiens Ostenf. and Halophila baillonis Asch. ex Dickie. Species descriptions, an identification key, and information on geographic distributions and habitats of the five taxa are presented. All species are native but only Halodule emarginata is endemic to Brazil, and is reported here as a new record for Piauí, extending its range northwest from the coast of the neighbouring state of Ceará.

“…In contrast, H. decipiens has been correctly reported for the Caribbean of Costa Rica, with many herbarium samples, and it is currently present at Isla Uvita. Nonetheless, H. baillonis has recently been reported in the Caribbean Sea at Belize (Short, Fernandez, Vernon, & Gaeckle, 2006), Honduras (Caviedes-Sánchez & Carrasco, 2016), and in the Atlantic coast of Brazil (Barros, Costa, & Rocha-Barreira, 2014;Magalhães, Borges, & Pitanga, 2015); thus, the record by Dawson (1962) may have been correct, and it is also possible that this inconspicuous species may still be found along the Caribbean coasts of Costa Rica.…”

Seagrass meadows are declining worldwide, mostly attributed to anthropogenic disturbances. Understanding the dynamics of these meadows is urgent in order to establish adequate management and conservation strategies. Here, we analyzed the current knowledge on the seagrass meadows in the Caribbean and Pacific coasts of Costa Rica, Central America. Current knowledge was based on literature searches, herbarium collections, informal interviews, and personal observations. We report a total of five genera and seven species for Costa Rica: Thalassia testudinum, Syringodium filiforme, Halophila decipiens, Halophila baillonis, Halodule wrightii, Halodule beaudettei, and Ruppia maritima. Six species are reported for the Caribbean, and four species for the Pacific. Thalassia testudinum, S. filiforme, and H. decipiens have only been reported for the Caribbean. Halodule beaudettei has only been reported for the Pacific coast. Halophila baillonis, H. wrightii and R. maritima have been reported for both coasts. Seagrasses were found at a total of 31 locations in Costa Rica, most from the Pacific coast; 16 of which are reported here for the first time. Seagrass meadows from both coasts are vastly different. Along the Caribbean coast, meadows are often dominated by the robust T. testudinum, they are extensive and stable, persisting for decades. In contrast, the meadows along the Pacific coast are more dynamic and are dominated by pioneer and smaller ephemeral species, such as H. baillonis and H. beaudettei. The number of studies on Costa Rican seagrasses is scarce but has been increasing over time, and mostly concern taxonomic reports and basic descriptions of the dynamics of T. testudinum meadows from the Caribbean. Research, conservation and management efforts on Costa Rican seagrass meadows would benefit from continued monitoring and research on associated fauna and flora, incorporating ecosystem resilience and services.

“…H. baillonis was registered in 1980 and 1988 in the state of Pernambuco, (surrounding Santa Cruz Channel, 9° 45' S) (DEN HARTOG, 1972;OLIVEIRA et al 1983), but it was not found again for at least three decades . Recently, the species has been reported on the northeastern coast of Brazil, between Piauí (Cajueiro da Praia, 2° 55' S) and Paraíba (Barra de Mamanguape, 6° 47' S), with at least two areas of well-established beds MAGALHÃES et al, 2015).…”

“…H. decipiens is generally found in association with H. wrightii, but in calm and protected areas with muddy sediment between 30 cm and 40 m depth (KEMPF, 1970;LABOREL-DEGUEN, 1963). H. baillonis occurs together with H. wrightii and H. decipiens in areas protected by reefs with strong turbidity and up to 3 m depth (MAGALHÃES et al, 2015). R. maritima meadows are found in estuarine areas, of which the Olho d'Água Lagoon in Recife, Pernambuco, where the sediment is muddy and has a high percentage of organic matter, is a good example (COELHO, 1965;CAZUZA, 2004).…”

Seagrass and Submerged Aquatic Vegetation (VAS) Habitats off the Coast of Brazil: state of knowledge, conservation and main threats

et al. 2016

Financial Support: This study was supported by the Brazilian Network for Coastal Benthic Studies -ReBentos (Programa SISBIOTA), Rede CLIMA and INCT for Climate Changes; sponsored by CNPq and FAPESP. Seagrass meadows are among the most threatened ecosystems on earth, raising concerns about the equilibrium of coastal ecosystems and the sustainability of local fisheries. The present review evaluated the current status of the research on seagrasses and submerged aquatic vegetation (SAV) habitats off the coast of Brazil in terms of plant responses to environmental conditions, changes in distribution and abundance, and the possible role of climate change and variability. Despite an increase in the number of studies, the communication of the results is still relatively limited and is mainly addressed to a national or regional public; thus, South American seagrasses are rarely included or cited in global reviews and models. The scarcity of large-scale and long-term studies allowing the detection of changes in the structure, abundance and composition of seagrass habitats and associated species still hinders the investigation of such communities with respect to the potential effects of climate change. Seagrass meadows and SAV occur all along the Brazilian coast, with species distribution and abundance being strongly influenced by regional oceanography, coastal water masses, river runoff and coastal geomorphology. Based on these geomorphological, hydrological and ecological features, we characterised the distribution of seagrass habitats and abundances within the major coastal compartments. The current conservation AbstrActPradarias de gramas marinhas e vegetação aquática submersa (VAS) estão entre os ecossistemas mais ameaçados do planeta, gerando preocupação sobre o equilíbrio dos ecossistemas costeiros e a sustentabilidade das pescarias. A presente revisão avaliou o estado do conhecimento sobre as pradarias marinhas e VAS do Brasil, considerando as respostas das plantas às condições ambientais, e o possível papel da geomorfologia costeira e variabilidade climática sobre a distribuição e abundância das populações. Apesar do crescente aumento no número de publicações, a comunicação dos resultados ainda é relativamente limitada e destina-se principalmente ao público nacional ou regional. Como resultado, as pradarias de gramas marinhas da América do Sul raramente são incluídas ou citadas em revisões e modelos globais. A escassez de estudos em larga escala e de longo prazo, permitindo a detecção de mudanças na estrutura, abundância e composição dos habitats e espécies associadas, limita a investigação das comunidades no que diz respeito aos efeitos potenciais das mudanças climáticas. Pradarias marinhas e VAS ocorrem ao longo de toda a costa brasileira, mas a distribuição e abundância das espécies são influenciadas pela oceanografia regional, massas de água costeiras, descarga de rios e geomorfologia costeira. Com base nas características oceanográficas, geomorfológicas, hidrológicas e ecológicas, o estudo discutiu a distr...
