(Sociedad de Biologia de Chile, 2009)Plant regeneration is strongly determined by light and soil moisture differences between habitats; both variables are modified by large-scale forest fragmentation. Several studies have indicated this alteration as the ...
-
(American Museum of Natural History, 2015)Darwin's naturalization hypothesis (DNH) states that the successful establishment of alien species is favored when the phylogenetic relationship between the colonizer and the recipient community is distant. From a population ...

(Universidad de Chile, 2002)Se realizó un experimento de respuesta de tabla de vida (ERTV) para investigaros efectos en }as variables de historia de vida de Stratidrilús aeglaphilus, al ser sometido a una difusión a1 50% de la contaminación ...
-
(Universidad de Chile, 2021-07)La interacción antagónica que involucra a las plantas y sus insectos herbívoros es un proceso ecológico con un gran impacto sobre la biodiversidad y el funcionamiento de los ecosistemas terrestres. En distintas regiones ...

(2012)• Premise of the study: We isolated and characterized microsatellite markers for the California poppy, Eschscholzia californica, which is an invasive species in central Chile. • Methods and Results: A total of eight ...
-
(Universidad de Chile, 2013)Objetivo: Comprender en qué medida los nichos climáticos de las especies exóticas se conservan, es fundamental para evaluar su riesgo de invasión. El conservatismo de nicho ha sido recientemente cuestionado por la ...
-
(2004)Comparisons between regions with similar climates have traditionally helped to tackle big questions in evolutionary ecology and historical biogeography. We claim that plant invasion ecology can benefit greatly from further ...
-
(Universisdad de Chile, 2014)El peso de la semilla es un atributo de historia de vida hereda ble que impacta significativamente sobre la adecuación biológicas de las plantas. Su aumento ocurriría en desmedro del numero de semillas; de esta forma, los ...
-
(Elsevier, 2014)The utility of spatial conservation prioritization (SCP), could be limited by the biases produced by taxonomic uncertainty and by the lack of an accepted taxonomic checklist for a diverse group of species. Using information ...

(Taylor and Francis Ltd., 2015)Background: The explosive growth of urbanisation in Mediterranean ecosystems in Chile has favoured the rapid expansion of exotic plant species, yet factors driving these invasion patterns in adjacent natural areas remain ...
-
(2013)Natural protected areas (ASP) located in the south-central Chile (Región Metropolitana-Región de la Araucanía) are a conservation relict embedded in agricultural and silvicultural matrices. We compared the taxonomic diversity ...
-
(2017)En la relación parásito-hospedero se ha evidenciado que ciertos parásitos pueden producir distintos cambios en sus hospederos, incluyendo alteraciones fisiológicas, morfológicas y/o conductuales. Un ejemplo de lo anterior ...
-
(Universidad de Chile, 2012)Las interacciones positivas constituyen un importante determinante de la estructura de poblaciones y comunidades vegetales. A nivel intraespecífico, las interacciones positivas incluyen al efecto Allee, el cual ha sido ...
-
(2011)Theory predicts that in more stressful environments, positive plant-plant interactions should be more important than negative ones. For instance, in arid and semiarid regions, amelioration of soil drought produced by the ...
-
(Wiley, 2012)Plant-animal interaction networks provide important information on community organization. One of the most critical assumptions of network analysis is that the observed interaction patterns constitute an adequate sample ...
-
(Universisdad de Chile, 2007)Los cambios en la estructura del paisaje generalmente son asociados a factores físico, biológicos y sociales. Sin embargo, es poco frecuente encontrar un análisis hecho de manera integrada. El objetivo de este estudio fue ...
-
(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 ...
-
(Universisdad de Chile, 2011)La invasiones biológicas son definidas como la introducción, establecimiento y dispersión de especies mas allá de su rango de distribución. Los nuevos ambientes pueden originar presiones selectivas sobre estas especies, ...
-
(Public Library of Science, 2014)©2014 Goncalves et al.Lantana camara, a native plant from tropical America, is considered one of the most harmful invasive species worldwide. Several studies have identified potentially invasible areas under scenarios of ...
