(Wiley, 2022)Mechanisms that reliably and efficiently guide practitioners to find relevant evidence are urgent for conservation decision-making in Chilean Patagonia. The objective of this study was to systematically collect, characterize, ...
-
(Universidad de Chile, 2010)Diversas investigaciones han mostrado que cultivos microbianos provenientes de una cepa pura pueden dar paso gradualmente a la emergencia y mantención de diversidad genética en condiciones de privación de recursos. En fase ...
-
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD., 2016)The avifauna of Chile is relatively depauperate, comprising 469 extant species, of which 213 are terrestrial. However, the Coquimbo Region presents a broad ecological transition from the hyperarid Atacama Desert to the ...

(ELSEVIER, 2006-07)Simple patch-occupancy models of competitive metacommunities have shown that coexistence is possible as long as there is a competition-colonization tradeoff such as that of superior competitors and dispersers. In this ...
-
(PUBLIC LIBRARY SCIENCE, 2007-09)Conservation priority-setting schemes have not yet combined geographic priorities with a framework that can guide the allocation of funds among alternate conservation actions that address specific threats. We develop such ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(International Association for Vegetation Science, 2015)QuestionThe biotic resistance hypothesis states that species diversity is a barrier for plant biological invasions because alien species are more likely to find strong competitors as diversity of native plants increases. ...
-
(2011)We analyzed the statistical distribution of intra-specifi c local abundances for a set North American breeding bird species. We constructed frequency plots for every species and found that they showed long-tail power-law ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2006-06)We assessed the geographic distribution of Tillandsia lomas in northern Chile, from Arica (18 degrees 20'S) to the Loa river (21 degrees 25'S) and discussed the factors that might potentially underlie the observed patterns. ...
-
(BLACKWELL, 2008-01)Increasingly, biogeographical knowledge and analysis are playing a fundamental role in assessing the representativeness of biodiversity in protected areas, and in identifying critical areas for conservation. With almost ...
-
(BLACKWELL, 2005-11)Aim We evaluated the phylogeography of sigmodontine taxa of the genera Phyllotis and Abrothrix at the intra and interspecific level, in the Atacama desert and adjacent Andean and Puna regions of northern Chile. The major ...
-
(UNIV CHICAGO PRESS, 2007-01)The effects of energy on food web structure have been debated for at least 80 years. Nevertheless, the empirical evidence is meager, especially from terrestrial ecosystems. We analyzed long-term temporal variation in food ...
-
(BLACKWELL, 2007-09)Understanding the factors that constrain and drive changes in food chain length represents an open challenge in ecology. Although several explanatory hypotheses have been proposed, no synthesis has yet been achieved. The ...
-
(SPRINGER, 2007-08)Forest bird species exhibit noticeable seasonal behavioral changes that might lead to contrasting effects of landscape pattern upon species abundance and performance. We assessed if the effect of patch and habitat attributes ...
-
(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 ...
