      1. A key aspect of the ecology and evolution of adaptive prey responses to predator risk is the timing by which the former develop a defensive trait in response to inducing signals released by the latter. This property, ...
    • Ramos Jiliberto, Rodrigo; Aránguiz Acuña, Adriana (Ecological Society of Australia, 2007)
      In this work we report on the seasonal trends of abundances in terms of temperature exposure for four coexisting cladoceran species (Daphnia ambigua (Daphniidae), Ceriodaphnia dubia (Daphniidae), Diaphanosoma chilense ...
    • Aránguiz Acuña, Adriana; Ramos Jiliberto, Rodrigo (Oxford University Press, 2014)
      Production of diapausing eggs in many zooplankton species occurs after partial switching from parthenogenesis to sexual reproduction. Storage effect theory predicts the stable long-term coexistence of competitors ...
    • Aránguiz Acuña, Adriana; Ramos Jiliberto, Rodrigo; Bustamante Araya, Ramiro (2011)
      The expression of phenotypically plastic traits in prey organisms, triggered by changes in the abundance of their predators, is customarily assumed to involve costs in some fitness components such as fecundity, growth or ...
    • Aránguiz Acuña, Adriana; Bustamante Araya, Ramiro; Ramos Jiliberto, Rodrigo (Oxford University Press, 2011)
      Theoretical predictions suggest that adaptive phenotypic plasticity, and induced defenses in particular, exert a stabilizing effect on ecological systems and increase the likelihood of species coexistence. Nonetheless, ...
    • Carvajal Salamanca, J. L.; Aránguiz Acuña, Adriana; Ramos Jiliberto, Rodrigo; Zúñiga, Luis R. (OXFORD UNIV PRESS, 2008-10)
      Studies of planktonic organisms have shown that various life-history traits, and consequently population growth rate, can be affected by chemical cues released by high densities of conspecifics. In this work we test for ...
    • García Sanz, Ignacio; Heine Fuster, Inger Andrea; Luque, José A.; Pizarro Martínez, Héctor Orlando; Castillo, Rodrigo; Pailahual, Matías; Prieto, Manuel; Pérez Portilla, Pablo; Aránguiz Acuña, Adriana (Nature, 2021)
      The Andean Altiplano-Puna is located at an elevation of approximately 4000 m.a.s.l. and is delineated by the Western and the Eastern Andes Cordillera. The high-altitude wetlands (HAWs) in the Central Andes are unique ...
    • Ramos Jiliberto, Rodrigo; Frodden, Ernesto; Aránguiz Acuña, Adriana (Elsevier, 2007)
      It has been reported that, in order to reduce mortality, prey are able to change their phenotype in response to cues released from predators. These short-time responses constitute effective antipredator strategies in ...
