Para narrarla, nos hemos sumergido en las fuentes primarias, en los testimonios directos de aquellos que fueron testigos y protagonistas de esta historia. Hemos escuchado las voces de poetas, cronistas españoles, exploradores franceses, científicos polacos, alemanes y visionarios chilenos; hombres que, de manera permanente o transitoria, se vincularon con esta tierra y dejaron por escrito sus impresiones, sus asombros y sus preocupaciones sobre los montes, las maderas, la leña y los frutos que definían el paisaje. 364 páginas Wed, 01 Jan 2025 00:00:00 GMT https://bibliotecadigital.infor.cl/handle/20.500.12220/33174 2025-01-01T00:00:00Z https://bibliotecadigital.infor.cl/handle/20.500.12220/33162 Trait variation between and within Andes and coastal mountain ranges in the iconic South American tree Araucaria araucana in Chile McIntosh, Mariah; González Campos, Jorge; Demaree, Patrick; Toro Salamanca, Omayra; Ipinza Carmona, Roberto; Bustamante Sánchez, Marcela Andrea; Hasbún Zaror, Rodrigo Jorge; Nelson, Cara A major barrier globally to achieving restoration goals is the identification and production of appropriate plant materials. To produce high-quality plant materials for restoration success, prevent negative consequences to plant populations, and conserve genetic diversity, it is critical to understand ecotypic variation among plant populations, especially in relation to environmental conditions. For Araucaria araucana, a highly threatened iconic South American tree that grows across a substantial climate gradient, this information is urgently needed to guide restoration and conservation efforts. We conducted a common garden experiment using seedlings from 12 populations of A. araucana across its range in Chile. This approach allowed us to assess regional (coastal versus Andes mountain ranges) and population-level variation in plant traits and relate this variation to environmental variables. Our results demonstrate that A. araucana exhibits differentiation at both regional and population levels, particularly in traits such as branch number and length (indicative of plant architectural differences) and needle width (reflecting variation in leaf investment). This variation is at least partly explained by climate variables, with the most significant differences attributed to regional variations in temperature annual range and mean vapor pressure deficit. Based on these findings, we recommend restoration efforts prioritize conserving genetic variation both among and within regions and their populations, while avoiding translocations of genotypes between coastal and Andes populations.

However, studies assessing the mechanisms underlying this variability (i.e., genetic differentiation and/or phenotypic plasticity) are highly limited for tree species, especially for those from the Southern Hemisphere. The aim of this study was to evaluate intraspecific variability in functional traits related to drought tolerance and the underlying mechanisms in Nothofagus obliqua (Mirb.) Oerst. (southern beech), an ecologically and economically important tree species in Chile. We measured 11 functional traits and tree radial growth in six populations growing in a common garden and at their site of origin across a latitudinal gradient in the Andean and Coastal Cordilleras of south-central Chile. There were significant differences in most of the evaluated drought tolerance traits across the gradient, although few of them exhibited a clinal trend. From the studied populations, two located in the northern and southern limits of the Coastal Range were the most drought tolerant, probably due to restrictive site-specific conditions. Only two traits, wood vessel proportion and tree-radial growth, were genetically differentiated with the wettest population having the largest radial growth. Plasticity to local environmental conditions is likely to be the key mechanism for Nothofagus obliqua adaptation to climate change. Finally, a weak but significant trade-off between growth and safety was found across the gradient, with populations from wetter environments growing faster and being less drought-tolerant than populations from drier sites. This is the first study of this type carried out in adult trees of the temperate forests of South America. In a climate change adaptation context, our results demonstrated that assisted migration of provenances cannot be broadly recommended, as some northern populations perform poorly when planted in the south.

Una mirada desde la silvicultura Larraín Larraín, Oscar; Romero-Mieres, Mario Este libro tiene por propósito, compartir con la ciudadanía y sector forestal en general, una mirada de los bosques nativos de la región de Ñuble en dos dimensiones. Primero centrando el interés en la conservación de los bosques nativos y las especies arbóreas principales que actualmente se encuentran amenazadas, mediante acciones silviculturales que promuevan su regeneración y conservación. Y segundo, aporta a la construcción de programas de restauración más integrales, que reconozcan la diversidad funcional de las especies en categoría de conservación, sus requerimientos ecológicos y las restricciones operacionales que implica su manejo. Asimismo, se busca orientar a profesionales, técnicos, propietarios y autoridades en la toma de decisiones informadas respecto al uso, protección y restauración de estas especies de manera de favorecer su desarrollo y permanencia en el ecosistema en el cual están insertas. 103 páginas Wed, 01 Jan 2025 00:00:00 GMT https://bibliotecadigital.infor.cl/handle/20.500.12220/33116 2025-01-01T00:00:00Z
