-
(PERGAMON-ELSEVIER, 2011-01)Antarctica is structured by a narrow and deep continental shelf that sustains a remarkable number of benthic species. The origin of these species and their affinities with the deep-sea fauna that borders the continent shelf ...
-
(SPRINGER, 2006-09)Pristine wilderness is a scarce global resource, but exotic species are so common that they constitute a principal component of worldwide ecological change. The relationship between these two topics, invasion and remoteness, ...
-
(Wiley, 2021)1. Invasive species have the ability to rapidly adapt in the new regions where they are introduced. Classic evolutionary theory predicts that the accumulation of genetic differences over time in allopatric isolation may ...
-
(Wiley, 2020)Studies on extrapair paternity (EPP) are key to understanding the ecological and evolutionary drivers of variation in avian mating strategies, but information is currently lacking for most tropical and subtropical taxa. ...
-
(ECOLOGICAL SOC AMER, 2006-03)Climatic changes associated with the El Nino Southern Oscillation (ENSO) can have a dramatic impact on terrestrial ecosystems worldwide, but especially on arid and semiarid systems, where productivity is strongly limited ...
-
(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. ...
-
(Wiley, 2021)Extra-pair behavior is present in 76% of socially monogamous bird species with biparental care. This behavior may produce costs to females related to a reduction in paternal care. We estimated the percentage of extra-pair ...
-
(BLACKWELL, 2006-08)The foraging ecology of hummingbirds involves the exploitation of a high number of patchily distributed flowers. This scenario seems to have influenced capabilities related to learning and memory, which help to avoid ...
-
(Academic Press-Elsevier, 2016)Endemic to South America, octodontid rodents are remarkable by being the only mammal taxa where allotetraploidy has been documented. The taxon's extensive morpho-physiological radiation associated to niche shifts has allowed ...
-
(Springer-Verlag, 2012)The Southern Ocean benthic communities are characterized by their levels of endemism and their diversity of invertebrate brooding species. Overall, biological processes acting within these species remain poorly understood ...
-
(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. ...
