The effect of seasonal and human pressure on macrobenthic fauna in the Caroni Swamp Ramsar Site, Trinidad and Tobago

Rev. biol. trop; 66 (3), 2018
Abstract Human pressures have placed many tropical estuaries in developing countries under increased levels of stress. The Caroni Swamp Ramsar Site, the largest mangrove swamp along the west coast of Trinidad, has been subjected to high levels of anthropogenic impacts including hydrological alteration an...

Marine Protected Area monitoring in the nearshore waters of Grenada, Eastern Caribbean: benthic cover and fish populations

Rev. biol. trop; 62 (supl.3), 2014
Grenada is highly dependent on coral reefs as a source of food and to support tourism. Local and global environmental stressors threaten these reefs. Legislation was created for this MPA in 2001, permanent mooring buoys were deployed in 2009 and enforcement of fishing restrictions began in 2010. Initiati...

Status of the coral reefs in Foul and Folly Bays, Morant Wetlands, south-eastern Jamaica, with emphasis on corals and macroalgae

Rev. biol. trop; 62 (supl.3), 2014
Foul and Folly Bays are located within the Morant Wetlands near the eastern tip of Jamaica. They have never been investigated but were believed to be important for larval productivity because of the extent of benthic habitats, absence of major coastal developments and remote location. The study was aimed...

The results of long term coral reef monitoring at three locations in Jamaica: Monkey Island, "Gorgo City" and Southeast Cay

Rev. biol. trop; 62 (supl.3), 2014
The global and regional impacts of climate change are having devastating consequences on the coral reef ecosystems of the Caribbean. Long term monitoring are important tool for assessing reef health. Monitoring was established in 2000 in the Bahamas, Belize and Jamaica. Following the pilot project, the p...

Estructura de las comunidades de corales y octocorales de Isla de Aves, Venezuela, Caribe Nororiental

Rev. biol. trop; 62 (supl.3), 2014
The Isla de Aves Wildlife Refuge is the northernmost portion of the Venezuelan territory generating 135 000km² of Exclusive Economic Zone. Studies on coral communities are scarce and old (1970s), due to its location 650km northeast of La Guaira Port and because it has military facilities. To upgrade bas...

Algas marinas bentónicas de la Isla Gorgona, costa pacífica colombiana

Rev. biol. trop; 62 (supl.1), 2014
The knowledge of the biodiversity of Gorgona, a continental island in Colombia, is very limited in the case of algae. We present an updated list of the benthic marine algae of Gorgona Island, associated with different marine environments and type of substrates, such as coral reefs, rocks, and soft bottom...

Marine biodiversity of an Eastern Tropical Pacific oceanic island, Isla del Coco, Costa Rica

Rev. biol. trop; 60 (supl.3), 2012
Isla del Coco (also known as Cocos Island) is an oceanic island in the Eastern Tropical Pacific; it is part of the largest national park of Costa Rica and a UNESCO World Heritage Site. The island has been visited since the 16th Century due to its abundance of freshwater and wood. Marine biodiversity stud...

Massive hard coral loss after a severe bleaching event in 2010 at Los Roques, Venezuela

Rev. biol. trop; 60 (supl.1), 2012
Thermal anomalies have become more severe, frequent and well-documented across the Caribbean for the past 30 years. This increase in temperature has caused coral bleaching resulting in reef decline. At Los Roques National Park, Venezuela, temperature has been monitored at four reef sites. In mid-Septembe...

Benthic and fish population monitoring associated with a marine protected area in the nearshore waters of Grenada, Eastern Caribbean

Rev. biol. trop; 60 (supl.1), 2012
Annual benthic and fish population surveys were completed at five locations in the nearshore waters along Grenada´s southwest coast during 2008-2010. Two survey sites are located in a newly launched Marine Protected Area (MPA). Photo Quadrat (PQ) and Point Line Intercept (PLI) surveys were used to deter...
