    • The negative effect of lianas on tree growth varies with tree species and seasonPalavras-chave 

      Venegas-Gonzalez, Alejandro [Univ Mayor, Fac Ciencias, Hemera Ctr Observac Tierra, Escuela Ingn Forestal, Chile]; Mello, Felipe N. A.; Schnitzer, Stefan A.; Cesar, Ricardo G.; Tomazello-Filho, Mario (Wiley-Blackwell, 2020-05)
      Lianas reduce tree growth, reproduction, and survival in tropical forests. Liana competition can be particularly intense in isolated forest fragments, where liana densities are high, and thus, host tree infestation is ...
    • Time-Series of Vegetation Indices (VNIR/SWIR) Derived from Sentinel-2 (A/B) to Assess Turgor Pressure in Kiwifruit 

      Jopia, Alberto [Univ Mayor, Fac Ciencias, Hemera Ctr Observac Tierra, Escuela Agron, Chile]; Zambrano, Francisco [Univ Mayor, Fac Ciencias, Hemera Ctr Observac Tierra, Escuela Agron, Chile]; Pérez-Martínez, Waldo [Univ Mayor, Fac Ciencias, Hemera Ctr Observac Tierra, Escuela Ingn Forestal, Chile]; Molina, Julio [Univ Mayor, Fac Ciencias, Escuela Agron, Chile]; Hoz Mardones, Felipe de la (MDPI AG, 2020-11)
      Simple Summary: Measures of plant water status on kiwifruit were evaluated using Sentinel-2 (A/B) for two seasons in Central Chile. For more than ten years, Central Chile has faced drought conditions, which impact crop ...
    • Tree-ring-based hydroclimatic reconstruction for the northwest Argentine Patagonia since 1055 CE and its teleconnection to large-scale atmospheric circulation 

      Hadad, Martin A.; González-Reyes, Alvaro [Univ Mayor, Hemera Ctr Observac Tierra, Escuela Ing Forestal, Fac Ciencias, Chile]; Roig, Fidel A. [Univ Mayor, Hemera Ctr Observac Tierra, Escuela Ingn Forestal, Fac Ciencias, Chile]; Matskovsky, Vladimir; Cherubini, Paolo (ELSEVIER, 2021-07)
      State-of-the-art climate models project droughts of stronger intensity and longer persistence in many arid and semi-arid regions such as northern Patagonia, which constitutes a serious concern worldwide. Moisture availability ...
    • Two Centuries of Hydroclimatic Variability Reconstructed From Tree-Ring Records Over the Amazonian Andes of Peru 

      Humanes-Fuente, V.; Ferrero, M. E.; Muñoz, A. A.; González-Reyes, A. [Univ Mayor, Hemera Ctr Observac Tierra, Escuela Ingn Forestal, Fac Ciencias, Chile]; Requena-Rojas, E. J.; Barichivich, J.; Inga, J. G.; Layme-Huaman, E. T. (Chile. Universidad Mayor, 2020)
      Almost half of the tributaries of the Amazon River originate in the tropical Andes and support large populations in mountain regions and downstream areas. However, it is difficult to assess hydroclimatic conditions or to ...
    • Water Crisis in Petorca Basin, Chile: The Combined Effects of a Mega-Drought and Water Management 

      Muñoz, Ariel A.; Klock-Barria, Karin; Alvarez-Garretón, Camila; Aguilera-Betti, Isabella; Lastra, José A.; Chávez, Roberto O.; Barria, Pilar; Duncan, Christie; Rojas-Badilla, Moisés; LeQuesne, Carlos; González-Reyes, Alvaro [Univ Mayor, Fac Ciencias, Hemera Ctr Observac Tierra, Escuela Ingn Forestal, Chile] (Chile. Universidad Mayor, 2020)
      Since 2010, Chile has experienced one of the most severe droughts over the last century, the so-called mega-drought (MD). The MD conditions, combined with intensive agricultural activities and the current water management ...
    • Weakening of the Summer Monsoon Over the Past 150 Years Shown by a Tree-Ring Record From Shandong, Eastern China, and the Potential Role of North Atlantic Climate 

      Chen, Qiaomei; Zhang, Xiaojian; Chen, Feng; Zhang, Heli; Yuan, Yujiang; Yu, Shulong; Hadad, Martin A.; Roig, FA [Univ Mayor, Escuela Ingn Forestal, Fac Ciencias, Hemera Ctr Observac Tierra, Huechuraba, Chile] (AMER GEOPHYSICAL UNION, 2023-03)
      The causes of the decreased intensity of the East Asian summer monsoon (EASM) over the past 150 years are still not fully understood, although several studies have linked the monsoon weakening to the warming of tropical ...
