    • Alkaloids of the Cactaceae ? The Classics 
      Cassels Niven, Bruce (Natural Product Incorporation, 2019)
      Alkaloids of the Cactaceae have been studied for the last 120 years. The first half of that period provided the "classic" compounds, after which a large number of usually very similar analogs were isolated or determined ...
    • Assessing the geographic dichotomy hypothesis with cacti in South America 
      Arzabe, A. A.; Aguirre, L. F.; Baldelomar, M. P.; Molina Montenegro, M. A (Wiley, 2018)
      The Cactaceae is one of the most conspicuous and ecologically important plant families in the world. Its species may have specialist or generalist pollination systems that show geographic patterns, which are synthesised ...
    • Assessment of parasite-mediated selection in a host-parasite system in plants 
      Medel Contreras, Rodrigo (Ecological Society of America, 2000)
      A two-year field study was conducted to evaluate the potential of two cactus species, Echinopsis chilensis and Eulychnia acida, to evolve defensive traits against the parasitic mistletoe Tristerix aphyllus (Loranthaceae). ...
    • Corryocactus brevistylus (K. Schum. ex Vaupel) Britton & Rose (Cactaceae): Antioxidant, Gastroprotective ... 
      Areche Medina, Carlos; Hernández, Marco; Cano, Teresa; Ticona, Juana; Cortes, Carmen; Simirgiotis, Mario; Cáceres, Fátima; Bórquez, Jorge; Echeverría, Javier; Sepúlveda, Beatriz (Frontiers Media, 2020)
      Corryocactus brevistylus (K. Schum. ex Vaupel) Britton & Rose (Cactaceae) is a shrubby or often arborescent cactus popularly known as "sancayo" and produce an edible fruit known as "Sanky" which is consumed in Arequipa-Peru. ...
    • Effects of vector behavior and host resistance on mistletoe aggregation 
      Medel Contreras, Rodrigo; Vergara, Eliseo; Silva, Arturo; Arroyo, Mary T. K. (Ecological Society of America, 2004)
      t. Understanding the factors affecting parasite aggregation in natural host pop- ulations is one of the central questions in parasite ecology. While different biological mechanisms giving rise to aggregation have been ...
    • Factors affecting cactus recruitment in semiarid Chile: A role for nurse effects? 
      Cares, Rocío A.; Muñoz, Pablo A.; Medel Contreras, Rodrigo; Botto Mahan, Carezza (Elsevier GmbH., 2013)
      The nurse-protégé hypothesis states that adult plants of one species provide micro-environmental conditions that favor the establishment of seedlings of a second species with no effect for the first species. Several studies ...
    • An integrative approach to understanding the evolution and diversity of Copiapoa (Cactaceae), a threatened ... 
      Larridon, Isabel; Walter, Helmut E.; Guerrero, Pablo C.; Duarte, Milén; Cisternas, Mauricio A.; Peña Hernández, Carol; Bauters, Kenneth; Asselman, Pieter; Goetghebeur, Paul; Samain, Marie Stephanie (Botanical Soc Amer, 2015)
      PREMISE OF THE STUDY: Species of the endemic Chilean cactus genus Copiapoa have cylindrical or (sub)globose stems that are solitary or form (large) clusters and typically yellow flowers. Many species are threatened with ...
    • Phytochemical profiling of coryphantha macromeris (cactaceae) growing in greenhouse conditions using ... 
      Cabañas García, Emmanuel; Areche, Carlos; Jáuregui Rincón, Juan; Cruz Sosa, Francisco; Pérez-Molphe Balch, Eugenio (MDPI AG, 2019)
      Chromatographic separation combined with mass spectrometry is a powerful tool for the characterization of plant metabolites because of its high sensitivity and selectivity. In this work, the phytochemical profile of aerial ...
    • Quantitative natural history of a host-parasite relationship: the Tristerix-cactus system in semiarid Chile 
      Medel Contreras, Rodrigo; Botto Mahan, Carezza; Smith Ramírez, Cecilia; Méndez, Marco; Ossa, Carmen G.; Caputo, Luciano; González, Wilfredo L. (2002)
      We present quantitative information on the natural history of a host-parasite interaction that consists on the holoparasitic mistletoe Tristerix aphyllus (Loranthaceae) and its cacti host species. More specifically, we ...
