The growth inhibition of 12 native marine bacteria isolated from Aplysina sponge surfaces, the shell of a bivalve, and Phytagel immersed for 48 h in sea water were used as indicator of the antifouling activity of the extracts of 39 marine organisms (octocorals, sponges, algae, and zoanthid) collected in the Colombian Caribbean Sea and on the Brazilian coast (Santa Catarina). Gram-negative bacte...

It is a fact that not only ships, but also seafarers and passengers vanish without a trace at sea, be it in the past or in present times. Several examples for this phenomenon are given. A scheme of the ship conditions found after discovering that single persons or even whole crews had disappeared from board is provided as an orientation, before describing in detail the more than 18 reasons for ...

submitted to the 25 Symposium on Sea Turtle Biology and Conservation. Night-time spectral sensitivity of adult female leatherback sea turtles Levenson, D.H., Eckert, S.A. Crognale, M.A., Duhamel, P., Kubis, S.A. and Harms, C.A. Flicker electroretinography (ERG) was used to measure the spectral sensitivity of adult female leatherback sea turtles in vivo on a nesting beach on the southern Caribbe...

This study describes the genetic diversity and population structure of 194 native maize populations from 23 countries of Latin America and the Caribbean. The germplasm, representing 131 distinct landraces, was genetically characterized as population bulks using 28 SSR markers. Three main groups of maize germplasm were identified. The first, the Mexico and Southern Andes group, highlights the Pr...

[1] A conundrum exists regarding whether the sea-surface temperatures decreased or increased over the southern Caribbean and the western Tropical Atlantic region during the Younger Dryas when the North Atlantic cooled substantially and the Atlantic thermohaline circulation was weakened significantly. Despite the proximity of core locations, some proxy reconstructions record a surface cooling, w...

Recent study of marine macroalgal diversity of the Republic of Panama has led to a substantial increase in the number of seaweed species documented for the country. In this updated list of marine algae based on collections made in 1999 and reports from the literature, 44 Chlorophyta (43 species and one variety) are documented for the Pacific coast of Panama, including 27 new records. A comparis...

In their recent articles, Mortimer et al. (2007) and Bowen et al. (2007) imply that historical declines in hawksbill sea turtle (Eretmochelys imbricata) populations in the Caribbean together with new phylogenetic data provide solid evidence that hawksbills cannot be harvested on a sustainable level. We suggest that broad inferences on the impacts of harvesting based on phylogenetic data alone a...

Artificial ocean alkalinization (AOA) is investigated as amethod tomitigate local ocean acidification and protect tropical coral ecosystems during a 21st century highCO2 emission scenario. Employing an Earth systemmodel of intermediate complexity, our implementation of AOA in theGreat Barrier Reef, Caribbean Sea and SouthChina Sea regions, shows that alkalinization has the potential to countera...
