(Cell Press, 2015)
-
(Elsevier, 2021)Freshwater ecosystems are responsible for an important part of the methane (CH4) emissions which are likely to change with global warming. This study aims to evaluate temperature-induced (from 5 to 20 ◦C) changes on microbial ...
-
(1995)The diffusion coefficients of lithium in LixMoS2 (0 < x < 0.43) compounds were determined at different temperatures by the galvanostatic-pulse relaxation technique. In the temperature range studied, the diffusion ...
-
(Sociedad Mexicana de Fisica, 1998)The behavior of free surfaces and of grain boundaries of a bcc Zr system, close to the melting temperature, are investigated using molecular dynamics in combination with a tight-binding potential. Our system consists in ...
-
(Elsevier, 2018-04-11)Superstatistics (Beck and Cohen, 2003) is a formalism that attempts to explain the presence of distributions other than the Boltzmann–Gibbs distributions in Nature, typically powerlaw behavior, for systems out of equilibrium ...
-
(Sociedad Chilena de la Ciencia del Suelo, 2016)© 2016, Sociedad Chilena de la Ciencia del Suelo. All rights reserved.Global warming affects the carbon (C) pools in terrestrial ecosystems, accelerating biological processes that feed back into the phenomenon of climate ...
-
(ELSEVIER, 2004-10)This paper reports the results of a study on temperature inhomogeneities conducted on a thermal plume by using ultrasound scattering as a non-intrusive measurement technique. The plume rises from a metallic disk which can ...
-
(2016)Background: Among the predictions of the effect of future climate change, the impact of thermal conditions at local levels on the performance of individuals and their acclimation capacities is key to understanding animals' ...
-
(2013)How high-alpine plants confront stochastic conditions for animal pollination is a critical question. We investigated the effect of temperature on potential flower longevity (FL) measured in pollinator-excluded flowers and ...
-
(Kluwer Academic Publishers, 1994)Extensive mortality of silversides (Atherinidae), Odontesthes bonariensis, was recorded during July 1989 in the Rapel Reservoir. Temporal and spatial changes observed in biomass concentration (chlorophyll-a) through both ...
-
(Kluwer Academic Publishers, 1984)Rotifers were sampled at monthly intervals for a year at four monitoring stations in Rapel Reservoir (a hydroelectric impoundment) in Central Chile (34°02′S; 71°35′W). Fifteen species were identified, but only Keratella ...
-
(Wiley, 2020)Human activity has caused a deterioration in the health and population size of riverine species; thus, public policies have been implemented to mitigate the anthropogenic impacts of water use, watercourse transformation, ...
-
(Sociedad de Biologia de Chile, 2005)During lactation, both the nutritional and energetic requirements of suckling change gradually. These changes normally are accompanied by modifications in chemical composition of the milk. We investigated the temporal ...
-
(Blackwell Publishing Ltd, 2014)The study of complexity in two aspects of the magnetic activity in the Sun-Earth system is presented. We compare the temporal evolution of the magnetic fluctuations in the Earth's magnetosphere and the spatial distribution ...

(American Geophysical Union, 2014)The study of complexity in two aspects of the magnetic activity in the Sun-Earth system is presented. We compare the temporal evolution of the magnetic fluctuations in the Earth’s magnetosphere and the spatial distribution ...
-
(Wiley-Blackwell, 2016)Small mammals use plant species for gathering food resources and for shelter. Preferences for certain plant species are related to nutritional restrictions and behavioural patterns, which could be altered in the presence ...
-
(Springer Verlag, 2017)© 2016, Springer-Verlag Berlin Heidelberg.Several studies have suggested that penguins are undergoing a major restructuring of their feeding habits and distribution after drastic climatic changes in the Antarctic Peninsula ...
-
(Elsevier, 2015)Chagas disease is a zoonosis caused by the protozoan parasite Trypanosome cruzi and transmitted by triatomine insects to several mammalian species acting as reservoir hosts. In the present study, we assess T. cruzi-prevalence ...
-
(2002)Hydroxamic acids (Hx) contained in wheat are active mutagens which play an important role in the defence of the plant against aphids. Random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) dominant markers ...
