The invertebrate communities of the northern Chilean rivers are characterised by their marked endemism andspecificity of their community structure in different basins. The river systems located in the Atacama Desert are endorheicand are affected by the rainy period of January-February commonly known as the “Bolivian winter“. The present study isthe first report on the observations of arthropods...

The atmospheric circulation over the Bolivian Altiplano during composite WET and DRY periods and during HIGH and LOW index phases of the Southern Oscillation was investigated using daily radiosonde data from Antofagasta (Chile), Salta (Argentina), Lima (Peru) and La Paz (Bolivia), daily precipitation data from the Bolivian/Chilean border between 18° and 19°S and monthly NCEP (National Centers f...

The enzyme profiles of three major Brazilian Trypanosoma cruzi zymodemes (Brazilian Z1, Brazilian Z2, Brazilian Z3) and of two principal Bolivian zymodemes were compared. Relationships were assessed both intuitively and by calculating genetic distances. One of the Bolivian zymodemes, Bolivian Z1, was closely related to the Brazilian Z1. The second Bolivian zymodeme, Bolivian Z2, was related to ...

Data on the genetic background of Peruvian and Bolivian populations is still scarce. Studies have shown that mestizos (i.e. mixed, but of predominantly Native American ancestry) present several HLA alleles originally described in genetically isolated Amerindian tribes, and that Peruvian and Bolivian mestizos are closely genetically related. Using Reverse Line Blot Assay, HLA typing for Class I ...

Compared to other Bolivian ecoregions, the Prepuna and Puna in the Bolivian highlands are distinguished by low precipitation and low biological diversity. These factors have likely contributed to the perception that the Prepuna and Puna are less interesting for entomological studies, and reports of longhorned beetles from these regions remain scarce. Here, the first longhorned beetle record for...

Personality has been studied in all of the great apes, many Old World monkey species, but only a handful of New World monkey species. Because understanding the personalities of New World monkeys is crucial to understanding personality evolution in primates, we used the Hominoid Personality Questionnaire to assess personality in 55 common squirrel monkeys (Saimiri sciureus) and 40 Bolivian squir...

Anthropometry is important as clinical tool for individual follow-up as well as for planning and health policy-making at population level. Recent references of Bolivian Adolescents are not available. The aim of this cross sectional study was to provide age and sex specific centile values and charts of Body Mass Index, height, weight, arm, wrist and abdominal circumference from Bolivian Adolesce...

Biomphalaria amazonica Paraense, 1996 was collected from a permanent pond in the outskirts of the Bolivian city of Santa Cruz. Identification of the collected specimens was made by comparison with the original description of the species and with topotypic material in the collection of Instituto Oswaldo Cruz. Phylogenetic analysis confirmed that these Bolivian specimens belong to B. amazonica.

The absence of urban yellow fever virus (YFV) in Bolivian cities has been attributed to the lack of competent urban mosquito vectors. Experiments with Aedes aegypti from Santa Cruz, Bolivia, demonstrated infection (100%), dissemination (20%), and transmission of a Bolivian YFV strain (CENETROP-322).
