Díaz, María Francisca; Bigelow, Seth; Armesto, Juan J. (ELSEVIER SCIENCE BV, 2007-06)Since the 19th century, 41% of the land on Chiloe´ Island (418500S, 738400W) in Chile was cleared. Following clearing and burning, much of the converted land remains in sparse shrub cover. We hypothesized that the arrested ...

Root-Bernstein, Meredith; Fierro, Andres; Armesto, Juan J.; Ebensperger, Luis A. (2013)Background: Birds are important mobile link species that contribute to landscape-scale patterns by means of pollination, seed dispersal, and predation. Birds are often associated with habitats modified by small mammal ...

Núñez-Ávila, Mariela; Uriarte, María; Marquet, Pablo A.; Armesto, Juan J. (British Ecological Society, 2013)1. Forest fragmentation may intensify recruitment limitation through impacts on seed production, dissemination and seedling establishment processes. In an ancient mosaic of fog-dependent rain forest patches on coastal ...

del-Val, Ek; Armesto, Juan J.; Barbosa, Olga; Marquet, Pablo A. (2007)The landscape (matrix) surrounding habitat fragments critically affects the biodiversity of those fragments due to biotic interchange and physical effects. However, to date, there have been only a limited number of studies ...

Gutiérrez, Alvaro G.; Aravena, Juan Carlos; Carrasco Farías, Natalia V.; Christie, Duncan A.; Fuentes, Mauricio; Armesto, Juan J. (BLACKWELL PUBLISHING, 2008-09)Aim A major question with regard to the ecology of temperate rain forests in south-central Chile is how pioneer and shade-tolerant tree species coexist in old-growth forests. We explored the correspondence between tree ...

Díaz, Iván; Armesto, Juan J.; Reid, Sharon; Sieving, Kathryn; Willson, Mary F. (ELSEVIER SCI LTD, 2005-05)We show how Chilean forest bird species richness, abundance and guild structure changes as a function of structural properties of forest stands. We surveyed bird assemblages in two old-growth (>200 years), two mid-successional ...

Pickett, S. T.A.; Collins, S. L.; Armesto, Juan J. (1987)The study of succession has been hampered by the lack of a general theory. This is illustrated by confusion over basic concepts and inadequacy of certain models. This review clarifies the basic ideas of pathway, mechanism, ...
