Lymnaea viatrix and Lymnaea columella in the neotropical region: a distributional outline

A review of lymnaeid samples collected by the author from 106 localities in Mexico, Cuba, Jamaica, Haiti, Dominican Republic, Puerto Rico, Martinique, Saint Lucia, Guatemala, Costa Rica, Panamá, Ecuador, Peru, Bolivia, Chile, Argentina, Uruguay andBrazil showed that one of them (from Ecuador) belonged to Lymnaea cousini Jousseaume, 1887, and all the others to either L. viatrix Orbigny, 1835 or l. columella Say, 1817. The ranges of L. viatrix and L. columella overlap in Middle America, and in northern and southern South America (Venezuela-Colombia-Ecuador and northeastern Argentina-Uruguay-southernmost Brazil, respectively). L. viatrix was the only species found in Peru west of the Andes and in Chile, and is supposed to have migrated eastward to Argentina via the Negro river basin. The range of L. columella in South America is discontinuous. The species has been recorded from Venezuela, Colombia and Ecuador and, east of the Andes, from latitudes 15º S (central-west Brazil) to 35º S (La Plata, Argentina). Such a gap may be attributed to either introduction from the northern into the southern area, or migration along the unsampled region on the eastern side of the Andes, or extinction in the now vacant area. No lymnaeids have been found so far in Brazil north of latitude 15º S and in the Guianas.

Génétique et hypertension artérielle: qu'avons nous-appris ? [Hypertension genetics: what have we learned so far?]

Hypertension is a common, modifiable and heritable cardiovascular risk factor. Some rare monogenic forms of hypertension have been described, but the majority of patients suffer from "essential" hypertension, for whom the underlying pathophysiological mechanism is not clear. Essential hypertension is a complex trait, involving multiple genes and environmental factors. Recently, progress in the identification of common genetic variants associated with blood pressure and hypertension has been made thanks to large-scale international collaborative projects involving geneticists, epidemiologists, statisticians and clinicians. In this article, we review some basic genetic concepts and the main research methods used to study the genetics of hypertension, as well as selected recent findings in this field.

Clúster creatius en entorns urbans: 22@Bcn i Shoreditch East London

La localització de les empreses de nova economia en zones urbanes, a pesar que el factor distància no sigui important, no deixa de ser considerable pels seus avantatges que els suposa estar situades conjuntament en relació amb les infraestructures, consum, beneficis socioculturals, i facilitat en les transaccions cara a cara. És inevitable que el primer quart del segle vint-i-un estigui lligat a l’economia creativa de forma similar amb que el començament del segle vint estava íntimament lligat a l’economia industrial i la invenció del sistema de producció en massa. La ciutat també va jugar un dels papers més importants per al desenvolupament de “la nova economia industrial” a les albors del segle vint, com ho és la ciutat del coneixement que acull “la nova economia creativa” al segle vint-i-un. És evident que els resultats morfològics, socials, econòmics i urbans són ben diferents en ambdós fenòmens, però l’impacte a les ciutats és molt gran. L’objectiu d’aquest estudi és analitzar els mecanismes d’aglomeració (clustering) d’activitats competitives basades en creació de coneixement i de serveis avançats que estan al darrera de desenvolupaments punters a ciutats com Barcelona, el projecte 22@bcn, i East London, el projecte Shoreditch. L’esforç que han posat les autoritats locals en crear l’entorn apropiat per atreure i crear empreses innovadores, com a motor de desenvolupament d’algunes ciutats modernes europees ha resultat en el sorgiment de nuclis o centres urbans molt dinàmics que suposadament estan preparats i acullen punts de creació de coneixement (“Urban Knowledge Hubs”), amb una demanda i llocs de treball altament qualificats. Aquest és el cas dels projectes de Barcelona (22@bcn) i East London (Shoreditch).

Monetary policy strategies, financial institutions and financial markets in the Middle East and North Africa: an overview

Three polar types of monetary architecture are identified together with the institutional and market infrastructure required for each type and the kinds of monetary policy feasible in each case: a ‘basic’ architecture where there is little or no financial system as such but an elementary central bank which is able to fix the exchange rate, as a substitute for a proper monetary policy; a ‘modern’ monetary architecture with developed banks, financial markets and central bank where policy choices include types of inflation targeting; and an ‘intermediate’ monetary architecture where less market-based monetary policies involving less discretion are feasible. A range of data is used to locate the various MENA countries with respect to these polar types. Five countries (Iran, Libya, Sudan, Syria and Yemen) are identified as those with the least developed monetary architecture, while Bahrain and Jordan are identified as the group at the other end of the spectrum, reaching beyond the intermediate polar type in some dimensions but not others. The countries in between vary on different dimensions but all lie between basic and intermediate architectures. The key general findings are that the MENA countries are both less differentiated and less ‘developed’ than might have been expected. The paper ends by calling for research on the costs and benefits of different types of monetary architecture.
