Datos del proyecto

Bon Accord Lagoon (BAL), Tobago is home to a Thalassia testudinum (K.D. Koenig, 1805) dominated seagrass community and polychaetes usually show an affinity to seagrass beds compared to other environments. The objectives of this study were to investigate the polychaete community associated with the Thalassia beds in BAL and determine seasonal variation. Thirty–one polychaete families were ranked according to trophic categories as described by Fauchald and Jumars (1979) and updated where possible. Deposit feeders were the largest trophic group represented across both seasons in the BALwith Maldanidae being the most dominant. Based on functional traits of the community the environment at BAL can be regarded as healthy. This study establishes a much-needed baseline for future research and management of marine biodiversity in southwest Tobago.

Descripción del área de estudio BAL lies in the southwestern region of Tobago at latitudes 11°10ʹ and 11°11ʹN and longitude, 60°49ʹ and 60°51ʹ E. The seagrass community in BAL covers an area of approximately 102 ha.2 and extends in some places to a depth of approximately 6 m. The seagrass beds are found in three main areas: north of Sheebird’s Point in the back reef area, south of Sheebird’s Point, and in the Lagoon extending from east of Gibson’s jetty straight toward the southeastern end of Pigeon Point. Turtle grass, T. testudinum is the dominant seagrass species in the Lagoon while smaller areas of Halophila decipiens (Ostenfeld, 1902) and Halodule wrightii (Ascherson, 1868) are interspersed among the turtle grass. The dominant algal genera areAcanthophera, Padina, Bryopsis, Dictyota, Halimeda, and Caulerpa while corals such as Porites porites (Pallas, 1766) also occur in the lagoon among the seagrass beds.
Descripción del diseño The objectives of this study were: (i) Assess the polychaete community in Southwest Tobago and group them into trophic categories (ii) Compare the polychaete community across wet and dry seasons in BAL (iii) Establish the status of the environment inBAL based on the functional traits of the polychaete community and (iv) Establish a baseline for future environmental assessment of the benthic environment in southwest Tobago.

Métodos de muestreo

Benthic macrofauna were collected among seagrass beds within the Bon Accord Lagoon, Tobago during two sampling periods, the dry and wet seasons of 2018 (March and September, respectively) using a handheld PVC corer. The National Geography in Shore Areas (NaGISA) protocol for sampling seagrass infauna was used which involved immersing a 15 cm diameter corer to a depth of 10 cm and using a rubber bung at the top of the device to create a vacuum.

Área de Estudio The Bon Accord Lagoon is located on the southwest coast of Tobago, which is located 32 km northeast of Trinidad, in the southeast Caribbean.

Descripción de la metodología paso a paso:

  1. Core samples were sieved in the field using a 0.5 mm mesh screen. Samples were stained with Rose Bengal and preserved with a 10% formalin seawater mixture. The benthic organisms studied were polychaetes, which were sorted and identified to the lowest possible taxonomic level using the key: The Polychaete worms. Accepted taxa were checked against the World Register of Marine Species www.marinespecies.org

Propósito

The purpose of this data set is to provide a baseline for polychaete communities in Bon Accord Lagoon Tobago. These are useful environmental indicators upon which future work can build to monitor the health and status of the marine environment in this area.
