Situación poblacional del cóndor andino (Vultur gryphus) en las sierras de Córdoba. Population status of the Andean Condor (Vultur gryphus) in Sierras de Córdoba mountain range.

Existe una clara necesidad de obtener información científica y comprensible sobre la distribución actual, abundancia y el estado de conservación del cóndor andino (Vultur gryphus) en Córdoba. Las justificaciones de ello incluyen: 1) la información disponible es muy limitada y fragmentada, y es insuficiente para las decisiones de manejo, 2) el aparente aislamiento de la población de cóndor andino de Córdoba respecto a la principal distribución de la especie a lo largo de los Andes sudamericanos, hecho que merece especial consideración, 3) indicaciones de que la especie muestra signos de declinación a lo largo de su rango de distribución, y 4) el valor de la especie como ave carismática y componente clave de atracción turística en la provincia de Córdoba. Esta propuesta pretende llenar el vacío de información existente mediante los siguientes objetivos específicos: 1) relevar la distribución del cóndor andino en Córdoba, 2) evaluar el tamaño poblacional de la especie a través de relevamientos en sus colonias no reproductivas, y 3) obtener la información disponible de la literatura publicada, material arqueológico y de informantes calificados. Los métodos incluyen: a) relevamientos sistemáticos a campo, b) conteos poblacionales en aquellos sitios identificados como colonias no reproductivas de la especie, c) revisión bibliográfica, y d) entrevistas a informantes selectos como ornitólogos, guías turísticos, pobladores rurales locales clave, etc. La información obtenida proveerá una línea de base de la situación actual del cóndor andino en Córdoba, como así también los criterios necesarios y la metodología para un monitoreo continuado de la especie en el territorio provincial.

Three new andean species of Drosophila (Diptera, Drosophilidae) of the mesophragmatica group

Three new species of mesophragmatica group, Drosophila amaguana, Drosophila shyri and Drosophila ruminahuii from Pasochoa Forest Reserve, northern Ecuadorian Andes, are described. The two subgroups currently composing the mesophragmatica group are renamed as the mesophragmatica subgroup to which the first two species have been added, and the viracochi subgroup to which the latter species has been added. These subgroups are defined based on the direction of the basal scutellar setae, which are divergent in the species of the former subgroup and convergent in the latter.

The Experience of European Integration and the Potential for Integration in South America

The experience of the European Union is the most significant and far-reaching among all attempts at regional integration. It is, therefore, the most likely to provide some lessons for those world regions that are just beginning this complex process. In turn, the Common Market of the South (MERCOSUR) and the Andean Community (CAN) are among the regional integration projects that have reached the greatest level of formal accomplishment after the EU. MERCOSUR is a customs union that aspires to become a common market, while avowing the commitment to advance towards political integration. For its part, CAN is a customs union that has already developed supranational institutions such as a Commission, a Parliament and a Court of Justice. In both cases, however, words have progressively tended to wander far from deeds. One reason underlying this phenomenon may be a misunderstanding of the European experience with integration. In this article, we discuss the theories that have been developed to account for integration in Europe and may prove useful to understand integration elsewhere and put forward a set of lessons that could be drawn from the European experience. Subsequently, we introduce a description of the experience of integration in South America and reflect (critically) on how the theories and lessons drawn from the EU could be applied to this region –and beyond.

Of Coalition and Speed: Passage and Duration of Statutes in Uruguay's Parliament, 1985-2000

We report preliminary findings from analysis of a database under construction. The paper explores the legislative process in search for some of the alleged consequences of cabinet coalitions in a presidential system. Coalition effects should be less evident in the success of executive initiatives: strategic behavior hampers this intuitive measure of performance. Better measures, because less subject to strategic considerations, are the odds of passage of legislators' bills and the time proposals take to be approved. Thus measured, coalition effects are discernible. Analysis of the universe of proposals processed in the fragmented Uruguayan Parliament between 1985 and 2000 reveals that coalition, observed about half the period, swells success rates of coalition members by 60% on average (and by as much as 150% for those close to the president). Event history analysis shows that coalitions cut the wait for an executive bill by 3 months, 1/6th the average wait. The reverse effect is felt on the duration of legislators' bills.

Old and new Andean Sarcophagidae (Diptera)

Species of the genera Notochaeta, Weyrauchimyia, and Udamopyga are redescribed; new species of the latter genus, of Cuculomyia and of Dexomyophora are proposed, all from the Yungas Biological Province of Ecuador. Key to species of Udamopyga is given.

Prevalence of anti-Taenia solium antibodies in sera from outpatients in an Andean region of Ecuador

Sera from 9,254 individuals that presented at one of three outpatient clinics in Quito, Ecuador were assayed by indirect hemagglutination for the presence of antibodies reactive with antigens from Taenia solium cysts. Immunoblot anlysis of 81 selected sera with IHA titers ranging from 0 to 1,028 showed that a titer of maior ou igual a 32 was suggestive of exposure to the parasite. Nine percent (9 %) of the 9,254 patients had titers of 32 or greater. Of 3,503 sera from one clinic, which included sera from food handlers undergoing yearly physicals, 390 (11 %) were positive. In addition, a correlation with age was seen in some, but not all, populations. In situations where age-related effects were noted, the highest incidence was seen in the youngest (0-20 years) and in the oldest (51-60 years) group. Thus, a resurgence of infection after a period of lower prevalence may be developing. Overall, this study shows that cysticercosis is relatively common and potentially a serious health problem in this region.

Pre-Election Positions and Voting Behaviour in Parliament: Consistency among Swiss MPs

This article examines the determinants of positional incongruence between pre-election statements and post-election behaviour in the Swiss parliament between 2003 and 2009. The question is examined at the individual MP level, which is appropriate for dispersion-of-powers systems like Switzerland. While the overall rate of political congruence reaches about 85%, a multilevel logit analysis detects the underlying factors which push or curb a candidate's propensity to change his or her mind once elected. The results show that positional changes are more likely when (1) MPs are freshmen, (2) individual voting behaviour is invisible to the public, (3) the electoral district magnitude is not small, (4) the vote is not about a party's core issue, (5) the MP belongs to a party which is located in the political centre, and (6) if the pre-election statement dissents from the majority position of the legislative party group. Of these factors, the last one is paramount.

Human mixed infections of Leishmania spp. and Leishmania-Trypanosoma cruzi in a sub Andean Bolivian area: identification by polymerase chain reaction/hybridization and isoenzyme

Parasites belonging to Leishmania braziliensis, Leishmania donovani, Leishmania mexicana complexes and Trypanosoma cruzi (clones 20 and 39) were searched in blood, lesions and strains collected from 28 patients with active cutaneous leishmaniasis and one patient with visceral leishmaniasis. PCR-hybridization with specific probes of Leishmania complexes (L. braziliensis, L. donovani and L. mexicana) and T. cruzi clones was applied to the different DNA samples. Over 29 patients, 8 (27.6%) presented a mixed infection Leishmania complex species, 17 (58.6%) a mixed infection Leishmania-T. cruzi, and 4 (13.8%) a multi Leishmania-T. cruzi infection. Several patients were infected by the two Bolivian major clones 20 and 39 of T. cruzi (44.8%). The L. braziliensis complex was more frequently detected in lesions than in blood and a reverse result was observed for L. mexicana complex. The polymerase chain reaction-hybridization design offers new arguments supporting the idea of an underestimated rate of visceral leishmanisis in Bolivia. Parasites were isolated by culture from the blood of two patients and lesions of 10 patients. The UPGMA (unweighted pair-group method with arithmetic averages) dendrogram computed from Jaccard's distances obtained from 11 isoenzyme loci data confirmed the presence of the three Leishmania complexes and undoubtedly identified human infections by L. (V.) braziliensis, L. (L.) chagasi and L. (L.) mexicana species. Additional evidence of parasite mixtures was visualized through mixed isoenzyme profiles, L. (V.) braziliensis-L. (L.) mexicana and Leishmania spp.-T. cruzi.The epidemiological profile in the studied area appeared more complex than currently known. This is the first report of parasitological evidence of Bolivian patients with trypanosomatidae multi infections and consequences on the diseases' control and patient treatments are discussed.
