Investments in forest plantations have grown in the last 40 years thanks to implementation of the Decree Law 701. Planted forests currently account for 17.4% of the total national forest cover. The objective of the study is to analyse non-industrial forest owners’ perceptions of positive and negative externalities of forest plantations in four less developed municipalities of the Maule Region. We implemented a literature review, the estimation of an Expert’s Response Indicator (ERI), and the implementation of an Analytic Hierarchy Process (AHP) methodology for the analysis.

OJANGUREN AFFILASTRO,1 CAMILO I. MATTONI,2 AND LORENZO PRENDINI3 ABSTRACT We review the taxonomy of the Brachistosternus Pocock, 1893 scorpions of Chile, providing revised diagnoses, comprehensive distribution maps (based on all known locality records), and an illustrated key to all Chilean species of the genus. Two new species, Brachistosternus (Leptosternus) chango, n.sp., and Brachistosternus (Leptosternus) kamanchaca, n.sp., are described from northern Chile. The phylogenetic affinities of B. chango are unclear. Some characters suggest that this species may be related to Brachistosternus (L.) artigasi Cekalovic, 1974 but others suggest that it may be related to Brachistosternus (L.) roigalsinai Ojanguren Affilastro, 2002. Brachistosternus kamanchaca, in contrast, appears to be closely related to Brachistosternus (L.) donosoi Cekalovic, 1974 and other species from the plains of northern Chile and southern Peru´.

  • Production and Establishment Techniques for the Restoration of Nothofagus Alessandrii, an Endangered Keystone Species in a Mediterranean Forest
    New Forests (2020) 51:159–174 https://doi.org/10.1007/s11056-019-09724-x Production and establishment techniques for the restoration of Nothofagus alessandrii, an endangered keystone species in a Mediterranean forest Manuel Acevedo1 · Carolina Álvarez1,2 · Eduardo Cartes1 · R. Kasten Dumroese3 · Marta González1 Received: 4 October 2018 / Accepted: 29 May 2019 / Published online: 13 June 2019 © Springer Nature B.V. 2019 Abstract Ruil (Nothofagus alessandrii) is an endangered keystone species from the Mediterranean climate zone of Chile. Ruil’s fragile state of conservation urges development of restora- tion programs, but specifc protocols for nursery production and feld establishment that ensure plant survival are largely unknown. Therefore, we examined the efect on nitrogen (N) fertilization and container size during nursery production in combination with the use of mesh shelters after outplanting on survival and growth during the frst growing sea- son in the feld. First year outplanting survival of nursery-grown container seedlings was enhanced when seedlings were given nitrogen (N) during nursery production and deployed with mesh tree shelters in the feld. The volume of the container had no efect on out- planting survival and growth. Increasing N from zero to 200 mg N L−1 provided sufcient N levels, resulting in increased seedling height, root-collar diameter, shoot biomass, and total seedling N and phosphorous concentrations. Additional N provided by the 400 and 600 mg N L−1 treatments underwent luxury consumption by the seedlings with no fur- ther benefts in feld performance. Improved growth in the nursery, along with the use of mesh tree shelters after outplanting, especially during the typical summer drought, may be responsible for increased survival during the frst growing season.

WEEK 5 LESSON 9 GEOMORPHOLOGY: CASE STUDY BASED ON RECENT EARTHQUAKES Read the report with regard to earthquakes that occured in Chile in South America in 2010 and 2019. Answer the questions that follow. Chile is located on an active area known as the Ring of Fire, a horseshoe shaped area along the Pasific basin, in which around 90% of the world’s eartquakes and about 81% of the world’s largest earthquakes occur. Chile is largely located on the boarders of the Nazca plate and the continental South American plate. The subduction of the Nazca plate beneath the South American plate is causing high stress beneath Chile, making the country highly prone to large magnitude earthquakes.
