Este trabajo indaga los primeros años del Partido Comunista del Paraguay tomando como ejes su inserción como sección nacional de la Internacional Comunista y sus relaciones con esa organización mundial fundada a través de su órgano regional: el Secretariado Sudamericano. En primer lugar, se ocupa de los conflictos que tuvieron lugar entre la sección nacional paraguaya y la Komintern en un contexto de inminencia de la Guerra del Chaco (1932-1935). Estos desacuerdos estuvieron relacionados con las posibilidades de la sección paraguaya de aplicar las tácticas contra la guerra impulsadas por la In

Abstract:

Lepidobatrachus asper is a large to medium frog known from the Chaco lowlands of Paraguay and Argentina. We provide the first species record for the Brazilian Chaco, which extends the species geographical distribution ca. 73 km northeast from Puerto Casado, Alto Paraguay Departament, Paraguay. We also provide a distribution map and information about the species habitat conditions and diet. The Brazilian Chaco is still poorly surveyed, and the rapid environmental degradation can lead to local extinctions of certain species.

Abstract:

This essay compares two communities of common origin that now dwell in separate rural lowland South American settings, one in the Bolivian Chaco and the other in the Paraguayan Chaco (maps 1 and 2). South America's Gran Chaco is sparsely populated, averaging one person per three square kilometers (Censo Nacional Indígena [Paraguay], 2002). Nevertheless, the present essay takes as its analytic-theoretical point of departure a phrase invoked by Michael Warner in his 1999 book on queer publics in New York City: “Urban space is always a host space” (1999: 190).

Abstract:

The Chacoan peccary Catagonus wagneri is endemic to the dry thorn forest of the Gran Chaco of Paraguay, Argentina and Bolivia. Since its discovery by scientists in the 1970s its population has declined due to overhunting, habitat destruction, and possibly disease. As of 1989 about 5000 individuals are estimated to survive in the Paraguayan Chaco. Small dispersed populations still exist in Argentina and Bolivia, but more information is needed on the status of this species in those two countries. In Paraguay, Chacoan peccaries have almost disappeared from the two national parks within their rang

AbstractThis essay seeks to throw light on the missionary efforts undertaken by the Oblates of Mary Immaculate (OMI), a Roman Catholic congregation, among the Nivaclé in today's Paraguayan Chaco (Chaco Boreal), between 1925 and 1940. Based on current anthropological knowledge, it assesses a series of ethnographic observations made by Father Walter Vervoort, OMI, a paradigmatic missionary of the time. Besides, it considers various ambiguities, paradoxes, and mediations in the relationship between Indians, missionaries, and the military in a socio-political context dominated by the Chaco War bet

Abstract:

SummaryStudies of records of the Black-bodied Woodpecker Dryocopus schulzi through literature searches, communications with ornithologists, personal observations and data from museum specimens show that the distribution of the species is basically limited to xero-phytic chaco woodlands in western Paraguay, northern and central Argentina, and southern Bolivia. Its western limit is defined by the transition zone between the chaco and the semi-humid montane forest on the east Andean slopes of southern Bolivia and north-west Argentina; in the extreme south it extends into the dry deciduous woodlan

Synandrospadix vermitoxicus es una especie nativa del Gran Chaco (Bolivia, Paraguay y Argentina) y regiones aledañas. Se realizó una investigación etnobotánica con el fin de compendiar el conocimiento vernáculo referido a la planta: nombres comunes, usos, conocimientos varios, así como su papel en la vida social y cultural de distintos pueblos que habitan en las regiones donde crece. Este trabajo constituye una síntesis que reúne datos originales obtenidos in situ así como aquellos registrados por variadas fuentes bibliográficas. La información oral y el material de herbario se recolectó duran

Abstract:

The gecko genus Phyllopezus is distributed mainly along South America’s “Dry Diagonal” (Caatinga, Cerrado, and Chaco). The genus has been the subject of recent taxonomic analyses and includes four described species and seven candidate species referred to here as Phyllopezus pollicaris sensu lato. In Paraguay, Phyllopezus is known from the Chaco and Cerrado where it is abundant, and also from a small isolated population from a rocky hill formation named “Cordillera de Los Altos” (Los Altos mountain range). Here we analyzed genetic samples from across its range, including new samples from Paragu

Abstract:

SUMMARYActive Trypanosoma cruzi transmission persists in the Gran Chaco region, which is considered hyperendemic for Chagas disease. Understanding domestic and sylvatic transmission cycles and therefore the relationship between vectors and mammalian hosts is crucial to designing and implementing improved effective control strategies. Here we describe the species of triatomine vectors and the sylvatic mammal reservoirs of T. cruzi, in different localities of the Paraguayan and Bolivian Chaco. We identify the T. cruzi genotypes discrete typing units (DTUs) and provide a map of their geographical

Abstract:

Nausigaster flukei Curran is recorded for the first time from Argentina. New specimens were collected in Mendoza, Jujuy and La Rioja provinces (Argentina), in the Monte and Chaco Phytogeographical Provinces. New records broaden the distribution of this species previously known from Paraguay and south Brazil and represent the first record of the genus Nausigaster from Argentina since 1892.

Abstract:

Abstract A new species of rodent is added to the highly diverse genus Oecomys (Cricetidae, Sigmodontinae, Oryzomyini) based on specimens collected in the Argentinian provinces of Chaco and Formosa. The new species is characterized by a derived carotid circulatory pattern, a feature shared with O. concolor, O. mamorae, and O. sydandersoni. A unique combination of morphological, morphometric, and molecular characters, however, provides unambiguous evidence of its validity as a separate entity. Individuals of the new species are larger than other representatives of Oecomys, and their skulls have

Abstract:

Among the physiographic regions included in the central South American diagonal of open formations, the Chaco, with some endemic species, represents the southernmost dry area. In Brazil, the Chaco is found in southwestern corner of Mato Grosso do Sul state, mostly in the municipality of Porto Murtinho along the Paraguay and Apa rivers. From February 2008 to December 2009, we carried out an inventory of amphibians and reptiles in Porto Murtinho, using pitfall traps, time-limited searches, and occasional encounters. A total of 34 amphibian and 39 reptile species were registered. Although some ty

Abstract:

Plagiolabra von Schulthess has only two recognized species and both were only recorded previously from Argentina and Paraguay. The two species of the genus were collected in Brazil for the first time, indicating that the biota of Mato Grosso do Sul has elements of the Chacoan province, thus indicating the importance for conservation of this area which is the only representative of the Chaco biome in Brazil.
