“…Coral reefs are present along the coasts of Guatemala, El Salvador, Nicaragua, and Costa Rica (Glynn & Ault 2000). In these regions macroalgae are also present from 0.5 to approximately 20 m in depth (Fernández & Alvarado 2008, Bernecker & Wehrtmann 2009). Patches of coral and the widespread occurrence of rocky reefs, and their associated species of algae and invertebrates, could explain the strong affiliation for shelf waters exhibited by at least 8 of the foraging turtles, i.e.…”

Satellite telemetry has helped reveal migratory movements of sea turtles. We attached satellite transmitters (MK10 Pat Tags) to 10 post-nesting East Pacific green turtles Chelonia mydas from Nombre de Jesús, Costa Rica (in 2006Rica (in , 2007Rica (in and 2009) to track their movements, identify their foraging grounds, and elucidate their foraging behavior. Location data were analyzed by applying a switching state-space model to obtain daily position estimates and to differentiate between 2 behavioral modes (migrating and foraging). All post-nesting movements were along coastal routes ranging up to 1086 km from the nesting beach. Of the 10 turtles, 6 remained local residents of Costa Rica foraging in the Gulf of Papagayo (N = 2) and the Gulf of Santa Elena (N = 4). One individual moved southwards to the Gulf of Panama, and 3 other turtles migrated northwards to waters off the Gulf of Fonseca in northern Nicaragua, with one continuing its foraging movements northwards to coastal Guatemala. Home ranges during foraging varied widely among individuals, and the calculated size of feeding grounds ranged from 315 to 18 335 km 2 , the latter being the largest reported for this species. The fact that members of this nesting population inhabit coastal waters makes them vulnerable to human activities along the coasts of Central America. Our findings highlight the importance of Costa Rica and the coastal waters of Central America for the survival of the Endangered Costa Rican green turtles.

“…In general, sea turtles fast during the internesting period due to the lack of food availability in the breeding areas (Hays et al 2000), but some populations do feed during the nesting season (Hochscheid et al 1999;Tucker & Read 2001). Even though there was no seagrass and few algae were present on the bottom in the area near the nesting beach (Reina et al 2005;Bernecker & Wehrtmann 2009), our green turtles could have been consuming invertebrates (Amorocho & Reina 2007;Quiñones et al 2010). As a result, and because we could not observe turtles in the water, we cannot rule out foraging behavior.…”

Using satellite transmitters, we determined the internesting movements, spatial ecology and diving behavior of East Pacific green turtles (Chelonia mydas) nesting on Nombre de Jesús and Zapotillal beaches along the Pacific coast of northwestern Costa Rica. Kernel density analysis indicated that turtles spent most of their time in a particularly small area in the vicinity of the nesting beaches (50% utilization distribution was an area of 3 km(2) ). Minimum daily distance traveled during a 12 day internesting period was 4.6 ± 3.5 km. Dives were short and primarily occupied the upper 10 m of the water column. Turtles spent most of their time resting at the surface and conducting U-dives (ranging from 60 to 81% of the total tracking time involved in those activities). Turtles showed a strong diel pattern, U-dives mainly took place during the day and turtles spent a large amount of time resting at the surface at night. The lack of long-distance movements demonstrated that this area was heavily utilized by turtles during the nesting season and, therefore, was a crucial location for conservation of this highly endangered green turtle population. The unique behavior of these turtles in resting at the surface at night might make them particularly vulnerable to fishing activities near the nesting beaches.

“…The six new records increased the diversity of Caribbean Costa Rican seaweeds by 1.9 % over that previously reported by Bernecker & Wehrtmann (2009). Four new genera were recorded for Caribbean Costa Rica: Microdictyon, Rhipidosiphon, Predaea and Augophyllum.…”

“…Fernández & Alvarado (2004) later described the coral reef from Punta Cocles, including a list of the associated macroalgae. Then, Bernecker (2009) and Bernecker & Wehrtmann (2009) published an updated list of the macroalgae from both the Caribbean and Pacific coasts of Costa Rica. There are 396 species of benthic marine algae reported for both Pacific and Caribbean coasts of Costa Rica (84 Chlorophyta or green algae, 51 Ochrophyta-Phaeophyceae or brown algae, 1 Xanthophyceae or yellow-green algae, and 260 Rhodophyta or red algae), from which 287 are recorded from the Caribbean coast (Bernecker, 2009).…”

Marine macroalgae are highly diverse and play an important role in marine ecosystems, influencing ecological processes. Recording the algae diversity with precise taxonomic identification is required to understand the marine ecosystems. The biodiversity of macroalgae along the southern Caribbean coast of Costa Rica has been studied by several authors, and the updated checklist includes 396 species of benthic marine algae reported for both Pacific and Caribbean coasts of Costa Rica, from which 287 are recorded from the Caribbean. Eighty percent of the total specimens from the Caribbean coast deposited in botanical collections in Costa Rica were collected at Cahuita National Park, an area where most of the studies have been carried out. This study reports on the addition of five new species and one genus of marine benthic macroalgae to the Caribbean Costa Rican flora, found at the poorly studied reefs of Playa Chiquita (Punta Cocles) and Punta Uva. Sampling was directed, searching for benthic macroalgae at Chiquita beach (SCUBA diving and snorkel) and Punta Uva (snorkel only), during October 2014. Specimens were deposited in the Dr. Luis A. Fournier Origgi Herbarium of the University of Costa Rica (USJ). Most of the new records were Chlorophyta, followed by Rhodophyta and Ochrophyta-Phaeophyceae. We recorded four new genera for the Caribbean coast of Costa Rica: Microdictyon Decaisne, 1841, Rhipidosiphon Montagne, 1842, Predaea G. De Toni, 1936, and Augophyllum S.-M. Lin, S. Fredericq & M. H. Hommersand, 2003. In conclusion, is necessary to continue the detailed taxonomic works in the Caribbean coast, focusing on areas poorly studied, in order to improve our knowledge of the marine flora of Costa Rica.
