Isla ; Luis C. Cortizo ABSTRACT The coasts of southern Buenos Aires, Patagonia and Tierra del Fuego are dominated by cliff erosion. Mean rates of cliff retreat are estimated to be about 0.5-0.6 m/year by comparing old photographs with modern satellite images. Considering the height of the Patagonian and Fueguian cliffs (70 to 120 m), the volume of sediment eroded from these cliffs exceeded the volumes provided by the erosion of the cliffs of Buenos Aires (10 to 20 m height). These erosion rates support an estimated delivery of 217 million tons of sediment per year to the continental shelf, exceeding significantly the 22 millions of tons/year transported by the larger Patagonian rivers Negro and Colorado. -
First Record of an Extinct Marabou Stork in the Neogene of South America
First record of an extinct marabou stork in the Neogene of South America JORGE IGNACIO NORIEGA and GERARDO CLADERA Noriega, J.I. and Cladera, G. 2008. First record of an extinct marabou stork in the Neogene of South America. Acta Palaeontologica Polonica 53 (4): 593–600. We describe a new large species of marabou stork, Leptoptilus patagonicus (Ciconiiformes, Ciconiidae, Leptoptilini), from the late Miocene Puerto Madryn Formation, Chubut Province, Argentina. The specimen consists mainly of wing and leg bones, pelvis, sternum, cervical vertebrae, and a few fragments of the skull. We provisionally adopt the traditional system− atic scheme of ciconiid tribes. The specimen is referred to the Leptoptilini on the basis of similarities in morphology and intramembral proportions with the extant genera Ephippiorhynchus, Jabiru,andLeptoptilos. The fossil specimen resembles in overall morphology and size the species of Leptoptilos, but also exhibits several exclusive characters of the sternum, hu− merus, carpometacarpus, tibiotarsus, and pelvis. Additionally, its wing proportions differ from those of any living taxon, providing support to erect a new species. This is the first record of the tribe Leptoptilini in the Tertiary of South America. Key words: Ciconiidae, Leptoptilos, Miocene, Argentina, South America. Jorge I.

Lithium Extraction in Argentina: a Case Study on the Social and Environmental Impacts
Lithium extraction in Argentina: a case study on the social and environmental impacts Pía Marchegiani, Jasmin Höglund Hellgren and Leandro Gómez. Executive summary The global demand for lithium has grown significantly over recent years and is expected to grow further due to its use in batteries for different products. Lithium is used in smaller electronic devices such as mobile phones and laptops but also for larger batteries found in electric vehicles and mobility vehicles. This growing demand has generated a series of policy responses in different countries in the southern cone triangle (Argentina, Bolivia and Chile), which together hold around 80 per cent of the world’s lithium salt brine reserves in their salt flats in the Puna area. Although Argentina has been extracting lithium since 1997, for a long time there was only one lithium-producing project in the country. In recent years, Argentina has experienced increased interest in lithium mining activities. In 2016, it was the most dynamic lithium producing country in the world, increasing production from 11 per cent to 16 per cent of the global market (Telam, 2017). There are now around 46 different projects of lithium extraction at different stages. However, little consideration has been given to the local impacts of lithium extraction considering human rights and the social and environmental sustainability of the projects. With this in mind, the current study seeks to contribute to an increased understanding of the potential and actual impacts of lithium extraction on local communities, providing insights from local perspectives to be considered in the wider discussion of sustainability, green technology and climate change. -

Longevity and fecundity of Dichroplus maculipennis (Orthoptera, Acrididae) at non-outbreaking and outbreaking situations. Dichroplus maculipennis is one of the most characteristic and damaging grasshopper species of Argentina, mainly in areas of the Pampas and Patagonia regions. We estimated and compared the longevity and fecundity of adult female D. maculipennis under controlled conditions (30°C, 14L:10D, 40% RH) from individuals collected as last instar nymphs (VI) in the field and with a known recent history of low and high density conditions. Densities of D. maculipennis at the collecting sites were 0.95 individuals per m2 in 2006 and 46 ind/m2 in 2009, representing non-outbreaking and outbreaking situations, respectively. Adult female longev- ity in 2006 (67.96 ± 3.2 days) was significantly higher (p < 0.05) than in 2009 (37.44 ± 1.98 days). The number of egg-pods per female was 3.32 ± 0.44 for 2006 and 1.62 ± 0.26 for 2009. The average fecundity in 2006 (89.29 ± 11.9 eggs/female) was signifi- cantly greater (p < 0.05) than that in 2009 (36.27 ± 5.82 eggs/female). While it was observed that the oviposition rate was higher in 2006, this difference was not significant (p > 0.05). -

Emilio Pettoruti A Painter before the Mirror m - STOCKCERO - n iii Emilio Pettoruti A Painter before the Mirror iv Emilio Pettoruti The memoirs of Emilio Pettoruti ( La Plata 1892-Paris 1971) “A painter before the Mirror” was published a few years before the painter´s death. Not only do we witness the vicissi- tudes of his struggle in order to impose his works, but we also find key aspects of his aesthetic convictions. His ties with Fu- turism and Cubism, his appreciation of color and light, in short a conception of art that led him to evolve towards an original abstraction, as his last paintings so well demonstrate. His essential concepts about art and life are highlighted by an existence defined by his beliefs and passions”.

The eight species involved are the following: European hare (Lepus europaeus), European rabbit (Oryctolagus cuniculus), wild boar (Sus scrofa), and red deer (Cervus elaphus) were all introduced from Europe (Austria, France, Germany, and Spain) to either or both Chilean and Argentine Patagonia. American beaver (Castor canadensis) and muskrat (Ondatra zibethicus) were introduced from Canada to Argentine Tierra del Fuego Island (shared with Chile). The American mink (Mustela vison) apparently was brought from the United States of America to both Chilean and Argentine Patagonia, independently. The native grey fox (Pseudalopex griseus) was introduced from Chilean to Argentine Tierra del Fuego. -

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). -
