The jewel beetle species Chrysobothrisdesmaresti (Laporte & Gory, 1836) and Hiperanthastempelmanni Berg, 1889, have been recorded in Bolivia for the first time. Both species were collected on xeric Acacia trees. As indicated by their presence on Acacia and previous records, both species may be endemic to the arid intermountain valleys of the Southern Bolivian and Northern Argentinean Andes as w...

The Bolivian Amazon holds a complex configuration of people and forested landscapes in which communities hold secure tenure rights over a rich ecosystem offering a range of livelihood income opportunities. A large share of this income is derived from Amazon nut (Bertholletia excelsa). Many communities also have long-standing experience with community timber management plans. However, livelihood...

This study identifies the spatial and temporal trends, as well drivers, of fire dynamics in Bolivian Amazon basin. Bolivia ranks top ten countries terms total annual burnt, with fires affecting an estimated 2.3 million hectares forest 2020. However, comparison to Brazilian Amazon, there has been little research into regime Bolivia. The sparse limited literature on subject indicate that activity...

The Bolivian Andes flank one of Earth’s major topographic features and dominate sediment input into the Amazon Basin. Millennial-scale erosion rates and dominant controls on erosion patterns in this range are poorly known. To define these patterns, we present 48 erosion rate estimates, derived from analysis of in situ Be in quartz-bearing alluvium collected from the Upper Beni River basin. Eros...

To investigate human babesiosis in the Bolivian Chaco, in 2013 we tested blood samples from 271 healthy persons living in 2 rural communities in this region. Microscopy and PCR indicated that 3.3% of persons were positive for Babesia microti parasites (US lineage); seroprevalence was 45.7%. Appropriate screening should mitigate the risk for transfusion-associated babesiosis.

Bolivian sex workers were more likely than other employed women to report tuberculosis screening only if they reported HIV screening. Of all women with household tuberculosis exposure, <40% reported screening for themselves or their children. Coupling tuberculosis screening with sex workers' mandatory HIV screenings may be a cost-efficient disease-control strategy.

Zoonoses within wild reservoir host populations often occur focally obeying Pavlovskii's rules of "natural nidality". What appears to be a clear example is Bolivian hemorrhagic fever (BHF), a disease endemic to northeastern Bolivia. The etiological agent is Machupo virus (MACV, Arenaviridae). The vertebrate reservoir, identified 30 years ago, was Calomys callosus a wild rodent common to open bi...

To address inequitable access to health services of indigenous communities in the Bolivian highlands, the Bolivian Ministry of Health, with the support of Save the Children-Saving Newborn Lives, conducted operational research to identify, implement and test a package of maternal and newborn interventions using locally recruited, volunteer Community Health Workers (vCHW) between 2008 and 2010. T...
