  • Upper Paraná Atlantic Forest Program
    Upper Paraná Atlantic Forest Program The Upper Paraná Atlantic Forest – locally called Selva Misionera or Paranaense - is one of the world’s most biodiverse subtropical ecoregions. Spread across three countries – Argentina, Brazil and Paraguay – these forests are one of the planet’s most threatened areas as a result of past and present deforestation. Over the last decade, Fundación Vida Silvestre Argentina (FVSA), WWF’s associate organization, has been working towards the conservation of the forests of the Misiones Province. These forests –located in northeastern Argentina- are one of the largest forest blocks that still remains, and one of the few that still houses a jaguar population. From the heart of the jungle, FVSA-WWF’s office in Puerto Iguazú, just a few kilometers away from the impressive scenario offered by the Iguazú Falls, promotes conservation and sustainable development actions. Some of these undertakings are the Misiones Green Corridor and the Biodiversity Vision, a planning tool for the ecoregion. The Upper Paraná Atlantic Forest (UPAF) covers The Misiones Green Corridor was singled out in most part of the Misiones Province in northeastern the Biodiversity Vision as the most important area Argentina, and expands through the south of where to focus local actions with regional impact.

Argentina - a country where water domain is vested in the provinces - is governed by a federal government with specific powers of jurisdiction. Any conflicts between provinces concerning water rights must be adjudicated by the Supreme Court. The case of La Pampa vs. Mendoza established rules for the allocation of waters of interstate rivers. In doing this, the Court was following precedents of international law and jurisprudence, particularly as established in the United States. The controversy focused on the Atuel River, which the Court ruled was an interstate river. The province of La Pampa sued, claiming that its possessory rights on public interstate waters had been challenged by the province of Mendoza's autonomous development of such waters.

Earlier indices developed for Argentina (Velázquez, 2008; 2010a) provided basically two dimensions: a) socio-economic and b) environmental. Socio-economic dimension embraces such indicators as education, health and housing, while environmental one considers three aspects: nature-based recreational resources, socially constructed recreational resources and environmental problems.

  • New Radiometric 40Ar–39Ar Dates and Faunistic Analyses Refine
    www.nature.com/scientificreports OPEN New radiometric 40Ar–39Ar dates and faunistic analyses refne evolutionary dynamics of Neogene vertebrate assemblages in southern South America Francisco J. Prevosti1,2*, Cristo O. Romano2,3, Analía M. Forasiepi2,3, Sidney Hemming4, Ricardo Bonini2,5, Adriana M. Candela2,6, Esperanza Cerdeño2,3, M. Carolina Madozzo Jaén2,7,8, Pablo E. Ortiz2,7, François Pujos2,3, Luciano Rasia2,6, Gabriela I. Schmidt2,9, Matias Taglioretti10,11,12, Ross D. E. MacPhee13 & Ulyses F. J. Pardiñas2,14,15 The vertebrate fossil record of the Pampean Region of Argentina occupies an important place in South American vertebrate paleontology. An abundance of localities has long been the main basis for constructing the chronostratigraphical/geochronological scale for the late Neogene–Quaternary of South America, as well as for understanding major patterns of vertebrate evolution, including the Great American Biotic Interchange. However, few independently-derived dates are available for constraining this record. In this contribution, we present new 40Ar/39Ar dates on escorias (likely the product of meteoric impacts) from the Argentinean Atlantic coast and statistically-based biochronological analyses that help to calibrate Late Miocene–Pliocene Pampean faunal successions. For the type areas of the Montehermosan and Chapadmalalan Ages/Stages, our results delimit their age ranges to 4.7–3.7 Ma and ca. 3.74–3.04 Ma, respectively. Additionally, from Buenos Aires Province, dates of 5.17 Ma and 4.33 Ma were recovered for “Huayquerian” and Montehermosan faunas. This information helps to better calibrate important frst appearances of allochthonous taxa in South America, including one of the oldest records for procyonids (7.24–5.95 Ma), cricetids (6.95– 5.46 Ma), and tayassuids (> 3.74 Ma, oldest high-confdence record).

Herein we present two new distribution records that extend its southern limits towards localities with extremer environmental conditions than reported to date. San Antonio Oeste constitutes the southernmost finding for the continent (40º44’S), whereas Tandil is the infested locality with the coldest mean annual temperature in Argentina (14.17ºC). The projection of a previous distribution model for Ae. aegypti predicts these two cities as positive and suggests several other localities with suitable conditions for vector proliferation beyond its assumed distribution limits. Key words: dengue vector - South American distribution - extreme environmental conditions - Patagonia. Over half of the world’s population live in areas The current geographic distribution of Ae. aegypti at where Aedes (Stegomyia) aegypti (L.), the main vector the global scale and its potential spread under different of dengue, chikungunya, Zika and yellow fever, occurs.
