(SPRINGER, 2005-03)Soil nutrient availability directly enhances vegetative growth, flowering, and fruiting in alpine ecosystems. However, the impacts of nutrient addition on pollinator visitation, which could affect seed output indirectly, ...
-
(SPRINGER, 2006-04)Non-native (alien, exotic) plant invasions are affecting ecological processes and threatening biodiversity worldwide. Patterns of plant invasions, and the ecological processes which generate these patterns, vary across ...
-
(ELSEVIER, 2006-01)Urbanization is increasingly homogenizing the biota of less developed countries. Even though urban sprawl is a worldwide problem, most studies on the effects of urbanization, and the conceptual models have focused on ...

-
(ELSEVIER, 2006-03-01)Forest edges have been long recognized as the first landscape elements to be invaded by alien plant species in forest ecosystems. However, little is known about the role of forest edge type in invasive species patterns. ...
-
(SOCIEDAD BIOLOGIA CHILE, 2006-06)In recent years natural history has been derided by some scientists as an old-fashion endeavor that does not follow the model of "hard" science and therefore should be considered "dead" and replaced by modern ecology, ...
-
(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, 2006-02)Little is known about how animals acquire and use prior information, particularly for Bayesian patch assessment strategies. Because different patch assessment strategies rely upon distinct capabilities to obtain information, ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2007-01)Habitat fragmentation may modify ecological interactions such as herbivory, and these changes can impinge upon plant fitness. Through a natural experiment, we evaluated if herbivory, foliar survival and shoot growth of the ...
-
(SPRINGER, 2006-12)The red alga Mazzaella laminarioides is an economically important species with an extended latitudinal distribution along the Chilean coast. Its populations form mid-intertidal stands, several meters wide, and therefore ...
-
(OXFORD UNIV PRESS, 2007-07)Background and Aims The endemic tree Nothofagus alessandrii (Fagaceae) has been historically restricted to the coastal range of Region VII of central Chile, and its forests have been increasingly destroyed and fragmented ...
-
(BLACKWELL, 2007-01)The spatial structure of habitats contains physical barriers that restrict the performance of diverse behavioural tasks. In heterogeneous habitats, information acquisition may allow animals to improve the performance of ...
-
(ELSEVIER, 2005-12)In the past decade, there has been growing concern about the rapid degradation of marine ecosystems due to anthropogenic causes. Consequently, identifying priority areas for the conservation of marine biodiversity has ...
-
(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, 2006-02)We studied the effects of fragment size, vegetation structure and presence of habitat corridors on the reproductive success of the Des Murs' Wiretail (Sylviorthorhynchus desmursii Des Murs, Furnariidae), a small (10 g) ...
-
(SOCIEDAD BIOLOGIA CHILE, 2007-03)Successional shrublands created by clearcutting and burning of forests are frequent in Chiloe Island and surrounding mainland in southern Chile. These areas are characterized by seasonally waterlogged soils, and vegetation ...
-
(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 ...
-
(BRITISH HERPETOL SOC, 2006-01)Insuetophrynus acarpicus is a poorly known frog restricted to the temperate forests of the coastal range of Chile (39 degrees 25' S, 73 degrees 10' W). Until recently, this species was known only from one type locality ...

(BLACKWELL, 2006-12)While climatic extremes are predicted to increase with global warming, we know little about the effect of climatic variability on biome distribution. Here, we show that rainy El Nino Southern Oscillation (ENSO) events can ...
