Geografías imaginarias y el oasis del desarrollo. Cambio climático y la promesa del futuro esplendor (LOM, 2020)El libro nos invita a reflexionar sobre la promesa de un futuro esplendor que ha proyectado el discurso del desarrollo en el Chile de las últimas décadas. Tras esa imagen es posible observar y constatar importantes ...

(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 ...
-
(PUBLIC LIBRARY SCIENCE, 2008-03)The large and diverse population of Latin America is potentially a powerful resource for elucidating the genetic basis of complex traits through admixture mapping. However, no genome-wide characterization of admixture ...
-
(MDPI, 2022)Estimation of biodiversity patterns in poorly known areas is hampered by data availability and biased collecting efforts. To overcome the former, patterns can be estimated at higher taxonomic levels and larger spatial ...
-
(Elsevier Masson SAS, 2014)© 2014 Elsevier Ltd.Geographic variation of traits may represent the first step for evolutionary divergence potentially leading to speciation. Signals are behavioral traits of particular interest for the study of variation ...
-
(2012)Increasing research has attempted to clarify the links between animal personality and physiology. However, the mechanisms driving this association remain largely unknown, and knowledge of how ecological factors may affect ...
-
(Oxford University Press, 2020)Sound-producing organs generate acoustic signals that have a fundamental role in communication systems. In species exhibiting different biogeographic patterns, variations of these structures can explain a large part of ...

(Wiley, 2021)Effective communication requires a match among signal characteristics, environmental conditions, and receptor tuning and decoding. The degree of matching, however, can vary, among others due to different selective pressures ...
-
(OXFORD UNIV PRESS INC, 2010-08-06)Animal personalities are interindividual behavioral differences that are consistent across time or contexts. Increasing research is revealing the adaptive significance of personalities, although the mechanisms driving ...
-
(BLACKWELL, 2008-06)1. It has been proposed that habitats with low productivity, and hence low resource availability, may favour individuals with lower rates of resource use and energy expenditure. In birds, some studies have shown that basal ...
-
(Springer, 2020)The geographical distribution and ecological niche of the two circulating species of the Sporothrix genus in Venezuela was established. For this, 68 isolates of Sporothrix spp. from patients of different regions of the ...
-
(Elsevier, 2018-05)The presented study analyzed the presence and geographical distribution of the tropical and temperate lineages of Rhipicephalus sanguineus sensu lato in Chile. R. sanguineus s.l. ticks were collected from dogs at 14 sites ...
-
(Nature Publishing Group, 1993)Childhood acute lymphoblastic leukaemia (ALL) T and B precursor subtypes have been identified by standardised immunophenotyping in different geographic and ethnic settings. Comparison of the relative frequencies and estimated ...
-
(Elsevier, 2015)Objective: To describe the distribution of alcohol-attributable mortality (AAM) at the local level (345 municipalities) in Chile, including fully and partially attributable causes in 2009. Methods: AAM was estimated ...
-
(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. ...
-
(WILEY-BLACKWELL, 2016)Orestias ascotanensis is a killifish endemic to the Ascotan salt pan in the Chilean Altiplano, where it inhabits 12 springs with different degrees of isolation. This species is a suitable model for studying the effect of ...
-
(Public Library Science, 2020)Many freshwater ecosystems worldwide, and particularly Mediterranean ones, show increasing levels of salinity. These changes in water conditions could affect abundance and distribution of inhabiting species as well as the ...
-
(BLACKWELL, 2008-05)The movement of materials and organisms between ecosystems is a common process in nature. In the present study we investigate the hypothesis that the movement of consumers between ecosystems depends not only on the ...
