A COMMUNITY ANALYSIS OF THE SOFT BOTTOM MEGAFAUNA (CRUSTACEA, MOLLUSCA) FROM THE SOUTHWESTERN REGION OF SANTA MARTA, COLOMBIAN CARIBBEAN Boletín de Investigaciones
Arango,Claudia P.; Solano,Oscar D..
Soft bottom megabenthic communities have been poorly studied in the Caribbean Sea. In this study we describe the structure and species composition of a Crustacea-Mollusca megafaunal community based on beam trawl samples taken between 13 and 60 m depth at the southwestern region of Santa Marta, Colombian Caribbean. Classification and ordination analyses using abundance data of crustaceans and molluscs produced two main groups (A and C), which seem to be controlled by depth and sediment characteristics. Group A consisted of species collected at the deeper stations and high content of silts (between 30 and 60 m depth) and exhibited the highest density and biomass mean values. The decapod Chasmocarcinus cilindricus was found as the characteristic species for...

A monograph of the shallow-water Chalinidae (Porifera, Haplosclerida) of the Caribbean Naturalis
Weerdt, Wallie H. de.
All known species of the sponge family Chalinidae (Demospongiae, Haplosclerida) occurring in the shallower part of the Caribbean are described and taxonomically revised. The study is the result of collecting activities of the author and others throughout the Caribbean, and examination of type and other material in musea and institutes. In a previous revision of north-eastern Atlantic Chalinidae (De Weerdt, 1986, 1989), the family was subdivided into eight monophyletic species groups, with various states of the skeletal architecture as main synapomorphous (shared derived) characters. After examination of all available type species of the nominal genera of the family, the species groups are now given proper names, replacing the tentative names in the earlier...

A Revision of Neomegalotomus (Hemiptera: Alydidae) Neotropical Entomology
Schaefer,Carl W.; Ahmad,Imtiaz.
We recognize two species in Neomegalotomus, N. parvus (Westwood), the type species; and N. rufipes (Westwood). The two species are redescribed from type specimens, and are keyed. We synonymize the following species with Neomegalotomus parvus: N. simplex (Westwood), N. latifascia (Berg), and N. pallescens (Stål) (all new synonymies). We synonymize N. jamaicensis (Westwood) with N. rufipes (new synonymy). The type specimens of all species hitherto placed in the genus are also redescribed, except those of N. debilis (Walker) and N. vicinus (Westwood). N. parvus occurs from México through Central America into northern Argentina and east into Venezuela and adjacent Caribbean islands. N. rufipes is widespread in the Caribbean south towards Venezuela. The two...

A study of the dry forest communities in the Dominican Republic Anais da ABC (AABC)
García-Fuentes,Antonio; Torres-Cordero,Juan A.; Ruiz-Valenzuela,Luis; Lendínez-Barriga,María Lucía; Quesada-Rincón,Juan; Valle-Tendero,Francisco; Veloz,Alberto; León,Yolanda M.; Salazar-Mendías,Carlos.
This paper is a floristic and phytosociological study of the dry forest communities of the Dominican Republic. A total of 69 relevés in dry forest biotopes were carried out. The samples were subsequently subjected to Detrended Correspondence Analysis for the determination and study of possible groupings. The study does not cover tree formations growing on serpentines, nor the so-called semideciduous forests, peculiar to areas with higher rainfall. A total of nine phytocoenoses were identified. The most significant results led to the description of six new phytosociological associations: Simaroubetum berteroani(thorny dry forest on coastal dunes), Phyllostylo rhamnoidis-Prosopidetum juliflorae (southern Dominican disturbed dry forest), Consoleo...

A taxonomical study of benthic Prorocentrum species (Prorocentrales, Dinophyceae) from Anse Dufour (Martinique Island, eastern Caribbean Sea) ArchiMer
Chomérat, Nicolas; Bilien, Gwenael; Zentz, Frédéric.
About 30 benthic Prorocentrum species have been described, some of which producing okadaic acid and derivatives involved in diarrhetic shellfish poisoning. The western Caribbean has been extensively studied for benthic dinoflagellates associated with ciguatera, and fifteen Prorocentrum species were described from mangroves and coral reefs of Belize. In contrast, no study reported the diversity of this genus in the Eastern Caribbean, especially in the Lesser Antilles. This study adds to the biodiversity knowledge in Martinique Island by investigating one site of the Caribbean coast from 2010 to 2017. Sediment samples were collected each year in March and studied taxonomically. Identification was realized morphologically by scanning electron microscopy,...

ABUNDANCE OF THE EXCAVATING SPONGE CLIONA DELITRIX IN RELATION TO SEWAGE DISCHARGE AT SAN ANDRÉS ISLAND, SW CARIBBEAN, COLOMBIA Boletín de Investigaciones
Chaves-Fonnegra,Andia; Zea,Sven; Gómez,Martha L..
It is known that the encrusting and excavating Caribbean sponge Cliona delitrix may increase its abundance near sources of sewage. To ascertain whether its current conspicuousness in leeward reefs of San Andrés Island (SW Caribbean, Colombia) is related to organic pollution from local raw sewage discharges, quantitative data on density and cover of this sponge and other benthic components was obtained from belt and line transects at seven stations along the shallow (5-10 m deep) terrace. Coral mucus was sampled to quantify Escherichia coli bacteria, as an approximate indicator of sewage plume influence on benthic biota. A negative multiplicative regression between amount of E. coli in coral mucus and distance from the main raw sewage outlet demonstrated...

Agricultural Export Diversification in Latin America and the Caribbean AgEcon
Taylor, Timothy G.; Francis, Brian.
Agriculture, in general, and agricultural exports in particular, have long been critical to economic growth and development in Latin America and the Caribbean (LAC). Despite the importance of agriculture to the region and the vast amount of resources devoted to the promotion of agricultural export diversification in LAC, there has been virtually no research undertaken to assess the degree to which the agricultural export structures in LAC countries have in fact diversified. Using disaggregate data on agricultural exports over the 1961-2000 period for 10 LAC countries, entropy-based measures of diversification are computed and analyzed. The empirical results show that the post-1985 period has witnessed some degree of agricultural export diversification...

Analyse technico-économique de projets d'élevage d'ombrine (Sciaenops ocellata) en cages flottantes à la Martinique ArchiMer
Houel, S; Falguiere, Jean-claude; Paquotte, Philippe.
The availability in interesting sites and the zootechnical performances of tropical fish are two impo rt ant assets in favor of the development of fish farming in the Caribbean islands. This repor presents a technical and financial analysis of red drum farming projects in floating cages in Martinique(French West Indies). This project analysis makes it possible to compare the economic feasability of a small-scale production system with that of a semi-industrial one submitted to different technical constraints. The main criteria of the project analysis are the profitability of the funded capital, the financial feasability during the buildup period, the profitability at a steady state and the cost price. Production costs are hi gher in the the small-scale...

Assessing Domestic Demand for Organic and ‘Locally Grown' Produce on An ‘Organic Island': Dominica's Dilemma AgEcon
Boys, Kathryn A.; Willis, David B.; George, Seraphine; Hammig, Michael D..
The economy of Dominica faces a unique set of challenges. As with many other Caribbean nations, Dominica has historically been dependent upon agriculture. Over the past several hundred years, the island's economy has been largely supported through the concentrated mono-cropping of a variety of export-oriented crops including coffee, limes, vanilla, and bananas (FAVACA, 2008). Today, approximately 45% of Dominica's labor force is employed in the agricultural sector (FAVACA, 2008). While neighboring countries have economically benefited from tourism, due to its lack of white sand beaches, Dominica is not a typical tourist destination. Taking advantage of its landscape, rainforests, and diversity of natural wildlife, in an effort to diversify its economy...

Avicularia rickwesti sp. nov., a remarkable new species of Avicularia (Theraphosidae: Aviculariinae) from Dominican Republic Rev. Bras. Zool.
Bertani,Rogério; Huff,Jeremy.
A remarkable new species of Avicularia Lamarck, 1818, Avicularia rickwesti sp. nov., is described from Dominican Republic. Female specimens of the new species are unusual by having two very short and broad spermathecae with distal half strongly sclerotized, a feature not found in any other aviculariine. Additionally, it has the leg coxae with spiniform setae, smaller on leg I and prolateral leg II, larger, black on retrolateral leg II, prolateral and retrolateral leg III and prolateral leg IV. Males are unknown. The new species is known only from two localities, in southwestern Dominican Republic. This is the first record for the subfamily on Hispañola which is close to the northern boundary for the Aviculariinae distribution.

Biofuels Potential in Latin America and the Caribbean: Quantitative Considerations and Policy Implications for the Agricultural Sector AgEcon
Ludena, Carlos E.; Razo, Carlos; Saucedo, Alberto.
Rising oil prices has led to increased interest to replace domestic demand for liquid fuels for transport (petrol and diesel) with biofuel production (ethanol and biodiesel). One of the pioneers in biofuel production is Brazil, which since the 1970s has established a government program that promotes the production and consumption of ethanol. Currently, Brazil is the leading producer of ethanol in the world and has started also programs for biodiesel production based on soybeans, oil palm and other crops. Other countries in Latin America and the Caribbean have also expressed interest in biofuel production, and have started programs, and in some cases the legislation that promotes biofuel production. However, most of the analysis of biofuel crops has been...

Ciguatera fish poisoning in Brazilian traveler to Caribbean BJID
Neves Junior,Cidney K.; Goldani,Luciano Z..
ABSTRACT Ciguatera poisoning is the most common form of non-bacterial food-poisoning from fish worldwide. The incidence among Brazilians returning from high-risk regions is unclear because it is not a mandatory reportable disease. We describe a previously healthy 53-year-old Brazilian woman developed Ciguatera fish poisoning while traveling to Havana, Cuba. Physicians and health care professionals should advise travelers to avoid eating ciguatoxic fish species and potentially toxic fish species in the Caribbean islands. Despite the prognosis for most cases is good with a short duration of self-limited symptoms, early recognition of the identifying clinical features of ciguatera can result in improved patient care.

Ciguatoxin Occurrence in Food-Web Components of a Cuban Coral Reef Ecosystem: Risk-Assessment Implications ArchiMer
Díaz-asencio, Lisbet; Clausing, Rachel J.; Vandersea, Mark; Chamero-lago, Donaida; Gómez-batista, Miguel; Hernández-albernas, Joan I.; Chomérat, Nicolas; Rojas-abrahantes, Gabriel; Litaker, Wayne; Tester, Patricia; Diogène, Jorge; Alonso-hernández, Carlos M.; Dechraoui Bottein, Marie-yasmine.
In Cuba, ciguatera poisoning associated with fish consumption is the most commonly occurring non-bacterial seafood-borne illness. Risk management through fish market regulation has existed in Cuba for decades and consists of bans on selected species above a certain weight; however, the actual occurrence of ciguatoxins (CTXs) in seafood has never been verified. From this food safety risk management perspective, a study site locally known to be at risk for ciguatera was selected. Analysis of the epiphytic dinoflagellate community identified the microalga Gambierdiscus. Gambierdiscus species included six of the seven species known to be present in Cuba (G. caribaeus, G. belizeanus, G. carpenteri, G. carolinianus, G. silvae, and F. ruetzleri). CTX-like...
