(Pensoft, 2020)Functional traits that predict plant invasiveness are a central issue in invasion ecology. However, in many cases they are difficult to determine, especially for a large set of species. Climatic niche traits can overcome ...
-
(Universidad de Chile, 2015)Los coccinélidos (Coleoptera: Coccinellidae) son insectos beneficiosos al controlar plagas importantes de la agricultura. Una de las especies que ha sido introducida en diferentes países es Harmonia axyridis (Pallas), ...
-
(Universidad de Chile, 2005)La fragmentación y la pérdida del hábitat en la actualidad son las mayores amenazas para la biodiversidad. Generalmente actúan en forma simultánea y por esta razón sus efectos frecuentemente son confundidos, sin embargo, ...

(2010)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, ...
-
(ELSEVIER, 2007-12-15)As matrices form the major component of landscapes mosaics, assessing regeneration suitability for native species within matrices is relevant for conservation and mandatory if native remnant patches are scarce, small and ...
-
(PLOS One, 2014)Species climate requirements are useful for predicting their geographic distribution. It is often assumed that the niche requirements for invasive plants are conserved during invasion, especially when the invaded regions ...
-
(KLUWER ACADEMIC PUBL, 1997-05)Copper mining activities are very important in central Chile. Like other metals, copper is a nutrient for most plants at low concentration levels; however, at higher levels it may become toxic. At present, copper abundance ...
-
(Elsevier, 2020)The mechanisms which promote divergence in populations of phytophagous insects using alternative hosts depend on the characterization of hosts as different selective scenarios and the modeling of the demographic dynamics ...
-
(SPRINGER, 2007-09-09)Demographic responses of a commensal annelid of freshwater crayfish, Stratiodrilus aeglaphilus, to a sublethal organic enrichment were tested. Censuses of the S. aeglaphilus population were performed every 3 days during ...
-
(Universidad de Chile, 2002)La fragmentación del hábitat puede afectar a las plantas al modificar su éxito reproductivo. Poblaciones más pequeñas y aisladas podrían experimentar reducción en la cantidad y calidad de semillas producidas, por cambios ...
-
(Sociedad de Biología de Chile, 2013)Pouteria splendens (lúcumo chileno, palo colorado) es un árbol endémico de Chile central con problemas de conservación. Es la única especie representante de la familia Sapotaceae en el país y se conoce muy poco de su ciclo ...

-
(Blackwell, 2007)Aim Taxonomic comparisons of alien floras across climatically similar regions have been proposed as a powerful approach for increasing our understanding of plant invasions across scales. However, detailed comparisons between ...
-
(Springer, 2010)Pollinator-mediated selection is one of the most important factors driving adaptation in flowering plants. However, as ecological conditions change through habitat loss and fragmentation, the interactions among species ...
-
(2009)The Chilean palm, Jubaea chilensis (Front Cover), one of the most emblematic tree species of the Chilean flora, has suffered a gradual reduction of its population numbers in the last 150 years, with the estimated 120,000 ...
-
(BLACKWELL, 2007-07)1. Ecosystem engineers are organisms that change abiotic conditions in ways that affect the performance and distribution of other species, including exotics. Several mechanisms have been proposed for the successful ...
-
(Universidad de Chile, 2005)La fragmentación per se es la subdivisión de un hábitat continuo en fragmentos más pequeños y aislados entre sí. La teoría predice que las abundancias poblacionales deberían disminuir a medida que aumenta la fragmentación ...
-
(Universidad de Chile, 2006)La fragmentación del hábitat es la transformación de un paisaje continuo en unidades más pequeñas y aisladas entre sí, inmersas en una matriz de estructura o composición diferente al paisaje original. La pérdida de hábitat ...
-
(ELSEVIER, 2008-10-15)Herbivory may be an important factor affecting seedling survival of exotic species invading new habitats. We evaluated the effect of vertebrate herbivory on the seedling survival of two widely planted and invasive tree ...
