Conflicts in connection with hydro-energy and mining activities vis-à-vis other water uses, mainly human consumption, agriculture, industry, tourism, or even the essential flows needed for ecosystem protection, call into question whether South America’s path in the 21st Century will be characterized as ‘open veins’ (borrowing from the title of Uruguayan writer Eduardo Galeano’s book) or sustainable development. In this era of ‘New Conquistadors’, as some have called it, the key question is whether water law and environmental legal frameworks in the region are fit to deal with the pressure posed by these extracting industries. The paper seeks to contribute to this debate by discussing legal issues in connection with a controversial gold mining project in the Argentina-Chile border and a hydro-energy project in the Chilean Patagonia. The goal of the paper is to provide a South American perspective of water law through the lens of conflict. The paper concludes that water-related conflicts in these projects reveal weaknesses in the regulatory scheme for such endeavours and underscores the need to adopt reforms or implement mechanisms to ensure that water resources are adequately assessed, protected, and monitored.

AbstractField observations during a journey through the arid regions of the South American Andes in June-July 1969 are evaluated in conjunction with available air photographs and reports from adjacent regions of the High Andes. Results indicate an increase of the Pleistocene snow-line depression in the western Cordillera from about 700 m at lat. 12° S. to more than 1 500 m at lat. 30° S. The Pleistocene snow-line depression decreases from the Pacific to the Atlantic side of the Andes, but particularly strongly so on the poleward fringe of the arid region. From this geomorphic evidence it is suggested that the atmospheric circulation during the glacial period was characterized by an Equatorward displacement of the boundary between tropical easterlies and temperate-latitude westerlies.


In Andean academia, a highly conservative environment, gender as a category of analysis has been an elusive and poorly understood concept. Despite the fact that in many countries of the Northern Hemisphere (where Euro-American knowledge is constructed), as well as South American countries, historians and anthropologists working from feminist perspectives have used gender theory since the 1980s, it is only in the 2010s that Andeanist scholars have begun to fully acknowledge that almost all historical narratives (from the Pre-Hispanic, Colonial, Republican and Contemporary Periods) excluded women as actors in all-important historical processes. As many Andean countries reevaluate their national republican discourses while celebrating the bicentennial of their independence, this flaw has become more evident. Hegemonic and historical accounts of South American independence movements, which highlight critical events and important historical figures, have focused on male figures and republican ideals mostly based on masculine values. Disseminating history from a masculine viewpoint, these narratives ignore women and other marginalized social groups, including indigenous and Afro-descendant communities, and fail to recognize their role as agents of political change. Consequently, using these narratives in the construction of national identities and citizenship has created social inequalities. The exclusion of women and nonbinary gender identities from the narrative has been noticed and acknowledged not only by academics, but also by society in general. Therefore, academic institutions and nonprofit organizations have promoted the publication and investigation of gender topics in history. However, archaeology, an isolated discipline immersed in its own discussions and dynamics, has developed in its own way. In general, opportunistic discoveries of “great and powerful women” have positioned archaeologists (mostly men) and their interpretations of the Andean past and power in an uncomfortable position. How to interpret these contexts using societal models that envision female bodies and feminine collectivities in a perpetually subordinated role? How to understand them without the tools of feminism and decolonial and anthropological theory? How to construct complex roles for Andean women in the past from a place in the present where that seems impossible and unimaginable (or even subversive)? From an Andean political awakening that takes a deep historical perspective, gender theory is under (de)construction. The topic of gender and history in the Andes is not about placing some female figures and mixing them up in an already hegemonic history; it is about creating innovative visions of the past, where multiple historical voices from the past and present appear.

Fruit-eating bats of the genus Artibeus are widely distributed across the Neotropics and are one of the most recently evolved assemblages of the family Phyllostomidae. Although the taxonomy and systematics of species of Artibeus has been the subject of an intense historical debate, the most current taxonomic arrangements recognize approximately eleven species within the genus. However, recent phylogenetic studies indicate that species diversity within South and Middle American populations of Artibeus is underestimated. South American populations referable to A. jamaicensis aequatorialis are of considerable interest because previous studies of mitochondrial DNA variation identified potential species level variation west of the Andes Mountains. In this study we use morphometric and genetic data (nuclear AFLPs) to investigate the taxonomic status of A. j. aequatorialis. Our results indicate that elevating aequatorialis to species level is appropriate based on statistically supported reciprocal monophyly in mitochondrial and nuclear datasets and diagnostic morphological characters. In light of our results, and of those presented elsewhere, we provide a revised classification of the genus.

A new species of the genus Colias Fabricius from the Arequipa region of Peru, C. misti Kir’yanov sp. nov., stat. nov., is established by raising it from the subspecies rank, C. lesbia misti Kir’yanov 2017. This taxonomic act is justified after detailed comparison of C. misti with representatives of phenotypically similar other South American Colias, including the subspecies of C. lesbia. The newly presented taxa are diagnosed by adult morphology, bionomics, and male genitalia. The diagnosis of a new subspecies Colias misti ccota Kir’yanov ssp. nov., discovered in the World’s deepest canyon Cotahuasi (Peru), is based on different and stable characters in phenotypes, genitalia, and bionomics of C. misti ccota and C. misti misti. Both subspecies of C. misti are endemic to the Western slopes of the Andes. It is also demonstrated that the shape of the male aedeagus is diagnostic for a reliable identification of the South American Colias.

The distribution of crustaceans of inland waters in southern Patagonia is characterized by the presence of sub-Antarctic and southern South American species. The aims of the present study were to study the geographical distribution of the calanoid copepod Boeckella brevicaudata (Brady, 1875) and the community structure of the zooplankton assemblages in which this species occurs. This last purpose was approached by applying null-models analyses based on species co-occurrence and niche-sharing. The species itself inhabits sub-Antarctic islands as well as southern South America. The results of the co-occurrence null model analysis revealed that the communities with this species have no regulating factors, whereas the niche overlap null model analysis revealed that these species share the same ecological niche. We thus found low abundances for all species, with specifically low B. brevicaudata abundance, at low mineral contents of the water. The results obtained were similar among sites in southern Argentinean and southern Chilean Patagonia, and on sub-Antarctic islands of which data were available.

ABSTRACT Nucleotide sequences were determined for the complete S genome segments of the six distinct hantavirus genotypes from Argentina and for two cell culture-isolated Andes virus strains from Chile. Phylogenetic analysis indicates that, although divergent from each other, all Argentinian hantavirus genotypes group together and form a novel phylogenetic clade with the Andes virus. The previously characterized South American hantaviruses Laguna Negra virus and Rio Mamore virus make up another clade that originates from the same ancestral node as the Argentinian/Chilean viruses. Within the clade of Argentinian/Chilean viruses, three subclades can be defined, although the branching order is somewhat obscure. These are made of (i) “Lechiguanas-like” virus genotypes, (ii) Maciel virus and Pergamino virus genotypes, and (iii) strains of the Andes virus. Two hantavirus genotypes from Brazil, Araraquara and Castello dos Sonhos, were found to group with Maciel virus and Andes virus, respectively. The nucleocapsid protein amino acid sequence variability among the members of the Argentinian/Chilean clade does not exceed 5.8%. It is especially low (3.5%) among oryzomyine species-associated virus genotypes, suggesting recent divergence from the common ancestor. Interestingly, the Maciel and Pergamino viruses fit well with the rest of the clade although their hosts are akodontine rodents. Taken together, these data suggest that under conditions in which potential hosts display a high level of genetic diversity and are sympatric, host switching may play a prominent role in establishing hantavirus genetic diversity. However, cospeciation still remains the dominant factor in the evolution of hantaviruses.
