Abstract:
... There is an unresolved debate as to whether natural disasters present true obstacles to a country's economic growth and development, given that the empirical evidence is rather heterogeneous. In this paper we explore whether aggregate analyses are likely to mask different responses of the components (export and import, government consumption, investment and private consumption) of Gross Domestic P ...
... Monitoring of benthic dinoflagellates is usually conducted between sub-surface and 5 m depth, where these organisms are supposed to be in highest abundances. However, only few studies have focused on the small-scale depth distribution of benthic dinoflagellates. In the present study, abundances of dinoflagellates were evaluated on an invasive macrophyte Halophila stipulacea in two coastal sites in ...
... The distribution of the Africanized honey bee (AHB) in the Caribbean region is “patchy”, with some islands, such as Puerto Rico, testing positive for AHB since the mid 1990s, while other regions, including the Dominican Republic and Haiti appeared to be free of AHB. In this study we confirm, through molecular test of mitochondrial genetic material, that AHB is now present in managed colonies in th ...

Abstract:
... Chromoblastomycosis is a mutilating infection of the skin and subcutaneous tissues caused by melanized fungi belonging to the order Chaetothyriales. Proven cases of the main agent, Fonsecaea pedrosoi are mainly limited to (sub)tropical, humid climates of Latin and Central America and the Caribbean. Fonsecaea monophora has a global distribution along the equator. Cases outside the (sub)tropics have ...
... Predators may have consumptive (lethal) and non-consumptive (sub-lethal) effects on prey. Non-consumptive effects include altered behavior and reduced growth and fecundity. Native prey may not recognize non-native predators as a threat, and therefore may suffer pronounced effects. Additionally, non-native predators may elicit different behavioral responses from prey compared to native predators. T ...
... The cryptic invader, Ferrissia californica (Rowell, 1863) (Gastropoda: Planorbidae), was identified using specimens collected in freshwater streams on Montserrat, West Indies using mtDNA sequences. This is the first record of a freshwater limpet from Montserrat and the third ancyline reported from the Caribbean. Freshwater limpets are small and difficult to find, which suggests that they are prese ...

Abstract:
... Information on amphibian diversity in Neotropical savannas and in protected areas in the Caribbean is lacking. We evaluated amphibian diversity and species composition in the Aripo Savannas Scientific Reserve in Trinidad, in relation to the two major habitat types, savanna and marsh forest. Thirty 200-m-long transects were sampled visually and aurally in 4 periods (total 120 samples), with 10 tran ...
... Diadromous fishes are known biotransport vectors that can move nutrients, energy and contaminants in an upstream direction in lotic ecosystems. This function has been demonstrated repeatedly in anadromous salmonids, but the role of other diadromous species, especially tropical taxa, as biotransport vectors is less studied. Amphidromous fish species exhibit potential to act as upstream vectors of n ...
