Notas Acerca de la distribución de Idiostolus insularis Berg, 1883 Hemiptera: Heteroptera: Idiostolidae) Resumen Se discuten y corrigen errores existentes acerca de los límites de la distribución de Idiostolus insularis Berg, 1883, estableciéndose Río Blanco, Curacautín, Región de la Araucanía *38°26’S-71°53’W+, como límite norte para esta especie. Se entregan nuevos registros que aportan nueva información acerca de la biología y distribución de esta especie. Palabras clave: Idiostolidae, Idiostolus insularis, distribución, Nuevo registro. Idiostolidae is a family of Heteroptera which shows a classic Gondwanaland distribution (Schaefer & Wilcox, 1969). There are few data about the biology of this family. It is only known that idiostolids are phytophagous insects and are associated with Nothofagus (Nothofagaceae) forests (Scudder, 1962; Schaefer & Wilcox, 1969). -
17.2 Present Situation and Outlook of Regional Integration Investments
17.2 Present Situation and Outlook of Regional Integration Investments and exports in the North Zone will be largely determined by the degree to which the macro-region is physically and institutionally integrated. At present, it is highly important to facilitate physical integration through the improvement of infrastructure and the transport system of export corridors. Institutional integration, e.g., standardized customs procedures, foreign investment laws, taxation systems, etc., is no less important than physical integration. Such development will widen and strengthen relations among economies of the macro-region and increase the possibility of handling export and import cargo and receiving foreign investment in the North Zone. Enterprises in the zone may also benefit from economies of scale while consumers will enjoy increases in the variety of goods and services available due to an expansion of their market. Cooperation between the private and public sectors and among central and local governments in the macro-region is indispensable for physical and institutional integration. This is because neither the private sector, nor the Chilean or regional governments of the North Zone, can carry out all necessary tasks alone. When the public sector renders support to improve physical and institutional infrastructure, particularly through international and inter-regional cooperation, the private sector’s interest in investing in the macro-region will be significantly increased. This will happen because such a situation will help investors minimize economic and political risks and maximize profits. 17.2.1 Regional Integration Schemes Institutional arrangements that can facilitate trade and investment in the macro-region include a customs union, a common market, a free trade agreement, a free trade zone, etc., but these schemes for regional economic integration are not new in South America. -

One of the most direct ways to evaluate this relationship is to measure the condition of the vegetation cover and land-use information. In southernmost South America there is a limited number of long-term studies on these matters, an incomplete network of weather stations and almost no database on ecosystems productivity. In the present work, we characterized the climate variability of the Magellan Region, southernmost Chilean Patagonia, for the last 34 years, studying key variables associated with one of its main economic sectors, sheep production, and evaluating the effect of extreme weather events on ecosystem productivity and sheep production. -
Torres Del Paine National Park, Patagonia – Chile 2012: Work Experience in Extreme Behavior Conditions 1 in the Context of Global Warming
Proceedings of the Fourth International Symposium on Fire Economics, Planning, and Policy: Climate Change and Wildfires Mega Wildfire in the World Biosphere Reserve (UNESCO), Torres del Paine National Park, Patagonia – Chile 2012: Work Experience In Extreme Behavior Conditions 1 in the Context of Global Warming René Cifuentes Medina2 Abstract Mega wildfires are critical, high-impact events that cause severe environmental, economic and social damage, resulting, in turn, in high-cost suppression operations and the need for mutual support, phased use of resources and the coordinated efforts of civilian government agencies, the armed forces, private companies and the international community. The mega forest fire that struck the Torres del Paine National Park and World Biosphere Reserve in the southern Magallanes region of Chile, in the period from December 2011 to February 2012, was caused by the negligent act of a tourist, in an area of difficult access by land and under extreme behavior conditions that made rapid access of ground attack resources even more difficult and made air attack impossible. Factors that influenced the event from the beginning were rapid rate of spread, high caloric intensity, resistance to control and long- distance emission of firebrands. On the other hand, the effects of climate change and global warming are being felt and viewed worldwide as a real threat, generating perfect scenarios for the occurrence of fires of this kind. Thus, this fire serves as a concrete example worthy of analysis for its magnitude, the considerable resources and means used, the level of complexity in attack operations, the great logistical deployments that had to be implemented due to the remoteness and inaccessibility of the site, the complications that had to be overcome, its impact on tourism and the local economy, the extensive media coverage it received, and its considerable political impact. -
Damage Assessment of the 2015 Mw 8.3 Illapel Earthquake in the North‑Central Chile
Natural Hazards https://doi.org/10.1007/s11069-018-3541-3 ORIGINAL PAPER Damage assessment of the 2015 Mw 8.3 Illapel earthquake in the North‑Central Chile José Fernández1 · César Pastén1 · Sergio Ruiz2 · Felipe Leyton3 Received: 27 May 2018 / Accepted: 19 November 2018 © Springer Nature B.V. 2018 Abstract Destructive megathrust earthquakes, such as the 2015 Mw 8.3 Illapel event, frequently afect Chile. In this study, we assess the damage of the 2015 Illapel Earthquake in the Coquimbo Region (North-Central Chile) using the MSK-64 macroseismic intensity scale, adapted to Chilean civil structures. We complement these observations with the analysis of strong motion records and geophysical data of 29 seismic stations, including average shear wave velocities in the upper 30 m, Vs30, and horizontal-to-vertical spectral ratios. The calculated MSK intensities indicate that the damage was lower than expected for such megathrust earthquake, which can be attributable to the high Vs30 and the low predominant vibration periods of the sites. Nevertheless, few sites have shown systematic high intensi- ties during comparable earthquakes most likely due to local site efects. The intensities of the 2015 Illapel earthquake are lower than the reported for the 1997 Mw 7.1 Punitaqui intraplate intermediate-depth earthquake, despite the larger magnitude of the recent event. Keywords Subduction earthquake · H/V spectral ratio · Earthquake intensity 1 Introduction On September 16, 2015, at 22:54:31 (UTC), the Mw 8.3 Illapel earthquake occurred in the Coquimbo Region, North-Central Chile. The epicenter was located at 71.74°W, 31.64°S and 23.3 km depth and the rupture reached an extent of 200 km × 100 km, with a near trench rupture that caused a local tsunami in the Chilean coast (Heidarzadeh et al. -

Alvarez Rojas1*, Fernando Fredes2, Marisa Torres3, Gerardo Acosta-Jamett4, Juan Francisco Alvarez5, Carlos Pavletic6, Rodolfo Paredes7* and Sandra Cortés3,8 Abstract This report summarizes the outcomes of a meeting on cystic echinococcosis (CE) in animals and humans in Chile held in Santiago, Chile, between the 21st and 22nd of January 2016. The meeting participants included representatives of the Departamento de Zoonosis, Ministerio de Salud (Zoonotic Diseases Department, Ministry of Health), representatives of the Secretarias Regionales del Ministerio de Salud (Regional Department of Health, Ministry of Health), Instituto Nacional de Desarrollo Agropecuario (National Institute for the Development of Agriculture and Livestock, INDAP), Instituto de Salud Pública (National Institute for Public Health, ISP) and the Servicio Agrícola y Ganadero (Animal Health Department, SAG), academics from various universities, veterinarians and physicians. Current and future CE control activities were discussed. It was noted that the EG95 vaccine was being implemented for the first time in pilot control programmes, with the vaccine scheduled during 2016 in two different regions in the South of Chile. In relation to use of the vaccine, the need was highlighted for acquiring good quality data, based on CE findings at slaughterhouse, previous to initiation of vaccination so as to enable correct assessment of the efficacy of the vaccine in the following years. The current world’s-best-practice concerning the use of ultrasound as a diagnostic tool for the screening population in highly endemic remote and poor areas was also discussed. -

Application of Technologies to Improve Nothofagus Pumilio Restoration in Chilean Patagonia
Application of technologies to improve Nothofagus pumilio restoration in Chilean Patagonia. Eduardo Arellano, Pontificia Universidad Católica de Chile, Chile. Additional Authors: Patricio Valenzuela, Pablo Becerra Throughout history Patagonian forests have been converted to other land uses such as grazing and mining. Surface coal mining in Chilean Patagonian region results in forest and grassland disturbance, altering the landscape and affecting sensitive vegetation naturally adapted to grow in extreme site conditions. Previous reclamation experiences have been focuses on restoring grassland using exotic herbaceous species. There are no local experiences on restoring native Nothofagus forest due to poor reforestation practices that not consider seedling sensibility to soil moisture stress and windy conditions that normally end in high seedling mortality. Using the forest reclamation approach model, we previously identified microsite conditions that promote natural regeneration. Despite the high landscape variability, natural forest regeneration occurs on microsite condition where shrubs and native grasses protect the seedling. Our objective was to explore which biotic and abiotic factors favor Nothofagus pumilio reforestation following anthropic disturbance. The study have been conducted in Magallanes Region in Chilean Patagonia, 130 Km north from Punta Arenas, in the Riesco Island. The climate is an oceanic climate bordering on a tundra climate. The seasonal temperature is greatly moderated by its proximity to the ocean, with average lows in July near −1 °C and highs in January of 14 °C, the average precipitation is 450 mm. We conducted a randomized split plot experiment to examine the effects of woody debris, shrubs, and shelters on seedlings growth, and survival during first year following planting in a mined site where top soil was replace and in grassland. -
