(Blackwell Publishing, 2014)Araucaria araucana (Araucaria) is a long-lived conifer growing along a sharp west-east biophysical gradient in the Patagonian Andes. The patterns and climate drivers of Araucaria growth have typically been documented on ...
-
(Nature Publishing Group, 2018)© 2018, The Author(s). Increasing evidence indicates that forest disturbances are changing in response to global change, yet local variability in disturbance remains high. We quantified this considerable variability and ...
-
(BLACKWELL, 2006-05)Understanding how animals interact with their environment is critical for evaluating, mitigating and coping with anthropogenic alteration of Earth's biosphere. Researchers have attempted to understand some aspects of these ...

(2000)Nothofagus species from Chile and New Zealand were surveyed in the field for invertebrate abundance and leaf feeding damage and in the laboratory for antifeedant activity against leafrollers (Ctenopsteustis obliquana, ...
-
(BIRKHAUSER VERLAG AG, 2006-09)The plant apparency hypothesis predicts that apparent plants invest in broadly effective defences such as tannins while unapparent plants invest in specific toxins such as alkaloids. The stress hypothesis states that plants ...

-
(2010)The effect of colonization on the distribution of genetic diversity within and among populations in relation to species characteristics remains an open empirical question. The objective of this study was to contrast genetic ...
-
(Academic Press, 2001)Berberidopsis corallina Hook. f. (Berberidopsidaceae) is a threatened vine, endemic to the temperate rainforests of southern Chile. A RAPD analysis was carried out to assess the extent of genetic variation in remaining ...
