(Blackwell Publishing Ltd, 2015)© 2015 John Wiley & Sons Ltd/CNRS.The strength of species interactions influences strongly the structure and dynamics of ecological systems. Thus, quantifying such strength is crucial to understand how species interactions ...
-
(2009)This study characterizes the structure of a plant-pollinator network in a temperate rain forest of Chiloé Island, southern Chile, where woody species are strongly dependent on biotic pollinators, and analyzes its robustness ...
-
(2010)Early work based on the Dynamical Systems Theory demonstrates that the larger the number of interacting populations, the system tends to be more unstable. Nevertheless, empirical evidence indicates that natural populations ...
-
(Universidad de Chile, 2009)En este estudio se analiza, mediante teoría de redes, la estructura de interacciones planta-polinizador de un bosque templado localizado en Ancud. Las propiedades topológicas de esta red como distribución de grado, anidamiento ...
-
(Universidad de Chile, 2018)Diversas actividades industriales generan como subproducto la liberación de metales pesados, que, al no ser degradables, se acumulan en el ambiente, incorporándose a las tramas tróficas y bioacumulándose, generando efectos ...
-
(2013)In this work the available information from scientific and technical studies is compiled and analyzed, to determine the taxonomic composition and trophic structure of river communities belonging to five hydrological basins ...
-
(Springer, 2014)Long-term studies of plant–pollinator interactions are almost nonexistent in the scientific literature. The objective of the present study was to determine changes and trends in the pollinator assemblage of ulmo (Eucryphia ...

-
(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 ...
-
(Blackwell, 2018)In nature species react to a variety of endogenous and exogenous ecological factors. Understanding the mechanisms by which these factors interact and drive population dynamics is a need for understanding and managing ...

(Universidad de Chile, 2013)El desarrollo de defensas en respuesta a señales químicas liberadas por depredadores es una estrategia plástica presente en muchas especies que habitan diferentes ambientes. Estas respuestas son expresadas como cambios ...
-
(Universisdad de Chile, 2008)En este estudio, se uso la aproximación de red compleja para evaluar la influencia de las plantas introducidas sobre una red de polinización real sujeta a perdida de hábitat. Mas específicamente, nos enfocamos en como la ...
-
(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 ...
-
(2009)The bidirectional relationship that aquaculture has with the environment set limits to the growth this economic activity has in Chile. This condition has generated both technical constraints and environmental as well as ...
-
(2013)Based on recent advances in ecological network theory, we present an ad hoc conceptual framework and a methodological proposal for the evaluation of the ecological relevance of species within a community, oriented towards ...
-
(Universisdad de Chile, 2012)Brachionus calyciflorus (Rotifera).tiene una fase reproductiva partenogenetica y una fase sexual, el estimulo que induce el cambio entre estrategias reproductivas, es la percepción de infoquimicos por alta densidad de ...
-
(Universisdad de Chile, 2011)Los organismos acuáticos están continuamente expuestos a una combinación de factores ambientales de distintos orígenes que afecta su adecuación biológica. Sin embargo se dispone de un entendimiento limitado acerca de la ...
