(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 ...
-
(Regional Euro-Asian Biological Invasions Centre (REABIC), 2020)Metridium senile is a circumboreally distributed sea anemone (Cnidaria: Anthozoa: Actiniaria) native to the northern hemisphere, and has been presumed as introduced to several locations in the southern hemisphere. Although ...

(AMER ORNITHOLOGISTS UNION, 2011-01)We assessed how individual foraging preferences and cognitive performance affect foraging bout interval and the flexibility of foraging behavior in the nectarivorous Green-backed Firecrown (Sephanoides sephaniodes). Our ...
-
(JOURNAL OF VISUALIZED EXPERIMENTS, 2014)Insufficient vascularization is considered to be one of the main factors limiting the clinical success of tissue-engineered constructs. In order to evaluate new strategies that aim at improving vascularization, reliable ...
-
(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 ...
-
(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 ...
-
(Springer, 2012)Colonising populations do not always exhibit founder effects. Common explanations are high levels of immigration and/or reproduction, but few empirical tests have been done. We measured genetic diversity of Nassauvia ...
-
(Public Library Science, 2016)Glacial episodes of the Quaternary, and particularly the Last Glacial Maximum (LGM) drastically altered the distribution of the Southern-Hemisphere biota, principally at higher latitudes. The irregular coastline of Patagonia ...
-
(Blackwell, 2012)Aim Our aim in this study was to document the global biogeographic variation in the effects of soil microbes on the growth of Centaurea solstitialis (yellow starthistle; Asteraceae), a species that has been introduced ...
-
(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. ...
-
(Elsevier, 2012)The prevailing view in the palaeoclimate literature of the last 20 years is that the Southern Westerly Winds (SWW) were intensified over southern Australia and Tasmania during the warmer-than-present early Holocene (11e8 ...
-
(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 ...
-
(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 ...

-
(Andean Geology, 2016)Two Holocene tephras encountered in outcrops, cores and trenches in bogs, and lake cores in the area around Cochrane, southern Chile, are identified (based on their age, tephra glass color and morphology, mineralogy, and ...
-
(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 ...
-
(Springer, 2015)Abstract Antarctic microorganisms have developed different strategies to live in their environments, including modifications to their membrane components to regulate fluidity and the production of photoprotective ...
-
(BLACKWELL, 2006-07)Ecosystem engineers are organisms able to modulate environmental forces and, hence, may change the habitat conditions for other species. In so doing, ecosystem engineers may affect both species richness and evenness of ...
