Distribution and habitat preferences of the genus Biomphalaria (Gastropoda: Planorbidae) in Cuba

A study was carried out to determine the distribution and habitat preferences of several species of the genus Biomphalaria. Samples were taken at 350 freshwater locations in Cuba. Three species of Biomphalaria (Biomphalaria havanensis, Biomphalaria helophila and Biomphalaria pallida) were recorded based on their distribution. Of the three species, B. havanensis has the weakest distribution because it was identified in only one locality. The other species, B. helophila and B. pallida, are abundant in rivers and dams and have large populations in Cuba. However, the only species that appears to occur in ecosystems shared with thiarids is B. pallida, possibly due to recent introduction of thiarids, but always in fewer numbers. Here we discuss the possibility of these species to act as intermediary hosts of Schistosoma mansoni in Cuba over the basis of occurrence in natural and anthropic habitats.

Bionomics of phlebotomine sand flies (Diptera: Psychodidae) in the province of Al-Baha, Saudi Arabia

The bionomics of phlebotomine sand flies (Diptera: Psychodidae) were studied for two successive years (January 1996-December 1997) at 12 collecting stations representing six sectors of the province of Al-Baha, Saudi Arabia. The predominant species was Phlebotomus bergeroti (41.7%), followed by lesser numbers of Phlebotomus sergenti (11%), Phlebotomus arabicus (10.6%), Sergentomyia tiberiadis (10.5%), Phlebotomus papatasi (10.2%), Sergentomyia antennata (9.6%), Phlebotomus alexandri (3%), Phlebotomus orientalis (2.3%) and Sergentomyia clydei (1.1%). The distribution of the collected species including species that are elsewhere known to act as vectors of human cutaneous leishmaniasis were distributed across different altitudes in Al-Baha. P. bergeroti, P. papatasi and P. arabicus were more abundant indoors; however, P. sergenti was more abundant outdoors. Sand fly populations exhibited three patterns of seasonal abundance in terms of their monthly activity. P. bergeroti, P. sergenti and P. arabicus were found to be naturally infected with Leishmania-like flagellates at an infection rate of 0.2%.

The European Union Perception of Cuba: From Frustation to Irritation

On Friday May 16, the Ministry of Foreign Affairs of Cuba summoned the newly-appointed charged’affairs of the European Commission in Havana and announced the withdrawal of the application procedure for membership in the Cotonou Agreement of the Africa, Caribbean, and Pacific (ACP) countries, and in fact renouncing to benefit from European development aid.1 In a blistering note published in the Granma official newspaper of the Cuban Communist Party, the government blamed the EU Commission for exerting undue pressure, its alleged alignment with the policies of the United States, and censure for the measures taken by Cuba during the previous weeks.2 In reality, Cuba avoided an embarrasin flat rejection for its application. This was the anti-climatic ending for a long process that can be traced back to the end of the Cold War, in a context where Cuba has been testing alternative grounds to substitute for the overwhelming protection of the Soviet Union

Proposta d’una metodologia pràctica: càlcul de potencialitats de captació de carboni en sistemes agroforestals a l'APA Itacaré/Serra Grande, Bahía- Brasil

En aquest projecte s’ha treballat amb una entitat no governamental, que es troba en la regió de Bahia (Brasil). L’associació “Mecenas da Vida” és una ONG que treballa en l’àmbit de la conservació del medi natural, fent partícips la pròpia població local. Petits agricultors dels municipis d’Itacaré i Uruçuca a l’Estat de Bahia que formen part del projecte, realitzen pràctiques conservacionistes i en compensació reben un pagament, per aquests serveis. Aquests diners provenen d’una taxa voluntària que paguen alguns empresaris turístics dels mateixos municipis. Pagant aquest import, els empresaris obtenen un segell distintiu que acredita la compensació de les seves emissions de CO2. El projecte tracta d’aportar un model de càlcul més específic al seuprograma de neutralització de carboni, amb sistemes agroforestals (SAF).No s’han trobat fonts d’informació sobre monitoratge de carboni en SAF en aquesta regió

Genetic origin, admixture, and asymmetry in maternal and paternal human lineages in Cuba

Background: Before the arrival of Europeans to Cuba, the island was inhabited by two Native American groups, the Tainos and the Ciboneys. Most of the present archaeological, linguistic and ancient DNA evidence indicates a South American origin for these populations. In colonial times, Cuban Native American people were replaced by European settlers and slaves from Africa. It is still unknown however, to what extent their genetic pool intermingled with and was 'diluted' by the arrival of newcomers. In order to investigate the demographic processes that gave rise to the current Cuban population, we analyzed the hypervariable region I (HVS-I) and five single nucleotide polymorphisms (SNPs) in the mitochondrial DNA (mtDNA) coding region in 245 individuals, and 40 Y-chromosome SNPs in 132 male individuals. Results: The Native American contribution to present-day Cubans accounted for 33% of the maternal lineages, whereas Africa and Eurasia contributed 45% and 22% of the lineages, respectively. This Native American substrate in Cuba cannot be traced back to a single origin within the American continent, as previously suggested by ancient DNA analyses. Strikingly, no Native American lineages were found for the Y-chromosome, for which the Eurasian and African contributions were around 80% and 20%, respectively. Conclusion: While the ancestral Native American substrate is still appreciable in the maternal lineages, the extensive process of population admixture in Cuba has left no trace of the paternal Native American lineages, mirroring the strong sexual bias in the admixture processes taking place during colonial times.

Música d’Amèrica Llatina del segle XX : el piano a l’Argentina, al Brasil i a Cuba

No podem pensar en una tradició musical llatinoamericana si no és a partir de la relació i confrontació de les cultures indígenes, africanes i europees, enteses des de la colonització fins a corrents immigratoris posteriors. El que es coneix com a nacionalisme musical va molt més enllà de les limitades barreres d'una nació o de la utilització de melodies i ritmes trets del folklore; consisteix en tot un procés de difusió i d'assimilació que sí que ens fa possible parlar d'unes produccions sonores pròpies, en aquest cas argentines, cubanes o brasileres. Enmig d'aquest context, els compositor llatinoamericans de música culta han hagut de fer una difícil elecció entre la música europea i la dels seus propis països, elecció que mitjançant aquest treball m'agradaria destacar.
