Nesting by three species of marine turtles persists in the Dominican Republic, despite historic threats and long-term population decline. We conducted a genetic survey of marine turtles in the Dominican Republic in order to link them with other rookeries around the Caribbean. We sequenced a 740bp fragment of the control region of the mitochondrial DNA of 92 samples from three marine turtle spec...

The hawksbill sea turtle, Eretmochelys imbricata, is an endangered species of the Caribbean Colombian coast due to anthropic and natural factors that have decreased their population levels. Little is known about the genes that are involved in their immune system, sex determination, aging and others important functions. The data generated represents RNA sequencing and the first de-novo assembly ...

background: for psychiatric disorders, comorbidity is a rule rather than exception. thus it is particularly important to study additive and multiplicative effects of multiple mental disorders on suicidal behaviors. objectives: the aim of this study was to investigate the ethnic differences in multiplicative effects of mental disorders on suicidal ideation among black adults in the united states...

The tiger shrimp Penaeus monodon is a native species of the Indo-Pacific Ocean that was introduced to promote its cultivation in several American countries, including Colombia. As result inappropriate aquaculture practices, it has established itself wild almost all Colombian Caribbean Sea. To evaluate genetic diversity, population structure, and origin founder populations, samples from three si...

The Caribbean Sea is the most species-rich sea in Atlantic, largely due to its vast coral reef systems. However, high biodiversity and endemism face unprecedented anthropogenic threats, including synergistic modern pressures from overfishing, climate change bioinvasion. Archaeological data indicate initial human settlement of ∼7000 years before present (yr BP), with regionally variable impacts ...

First records of peracarid crustaceans obtained from the Cayo Matías Ocean Blue Hole, southwestern Cuba, are documented. In addition, two new species of isopod and amphipod are herein described. Gnathia micheli n. sp. (Isopoda, Gnathiidae) and Boca normae n. sp. (Amphipoda, Aristiidae) were associated with filamentous algae at a depth of 20 m. Both represent the first report for a blue hole and...

We investigate the decision rules adopted by individuals in local communities, whose livelihoods depend on common pool resource stocks and who face the cooperation dilemma in their everyday life. For this purpose, field experiments are modeled and the model structure and output are confronted with experimental data and with the relevant theory of collective action proposed by Ostrom (1998). The...

Female green turtles exhibit strong nest-site fidelity as adults, but whether the nesting beach is the natal site is not known. Under the natal homing hypothesis, females return to their natal beach to nest, whereas under the social facilitation model, virgin females follow experienced breeders to nesting beaches and after a "favorable" nesting experience, fix on that site for future nestings. ...

Three new species of deepwater calocaridid shrimps are recorded from the Gulf of Mexico: Calastacus colpos, Calastacus mexicanus, and Calocaris caribbaeus. The latter species is also recorded from several sites in the Caribbean Sea. Calastacus colpos is characterised by flattened contiguous eyes, a single spine on the dorsal margin of the merus of pereopod I, and 3-4 spines on the uropodal sutu...
