-
(2013)Based on recent advances in ecological network theory, we present an ad hoc conceptual framework and a methodological proposal for the evaluation of the ecological relevance of species within a community, oriented towards ...
-
(2012)We compared the diversity of vines and vascular epiphytes among an evergreen forest fragment (Laureliopsis philippiana y Eucryphia cordifolia) and four fragments of secondary forest dominated for Nothofagus obliqua in an ...
-
(2013)In this work the available information from scientific and technical studies is compiled and analyzed, to determine the taxonomic composition and trophic structure of river communities belonging to five hydrological basins ...
-
(Institute of Physics Publishing, 2012)We present kinematical profiles and metallicity for the M31 dwarf spheroidal (dSph) satellite galaxy AndromedaII (AndII) based on Keck DEIMOS spectroscopy of 531 red giant branch stars. Our kinematical sample is among the ...
-
(2013)A novel methodology for the synthesis of S- and N-functionalized dithiocarbamates starting from cyclic sulfates, amines and carbon disulfide by using different protocols, including microwave assistance and a multicomponent ...
-
(2013)Using operator valued Fourier multipliers, we characterize maximal regularity for the abstract third-order differential equation αu′″ (t)+u″ (t) = βAu(t)+γBu′(t) + f(t) with boundary conditions u(0) = u(2π), u′(0) = u′(2π) ...
-
(2013)We study almost automorphic solutions of recurrence relations with values in a Banach space V for quasilinear almost automorphic difference systems. Its linear part is a constant bounded linear operator A defined on V ...
-
(2013)Phosphofructokinase-2 is a dimeric enzyme that undergoes cold denaturation following a highly cooperative N2 2I mechanism with dimer dissociation and formation of an expanded monomeric intermediate. Here, we use intrinsic ...
-
(2013)We present the first glacier inventory of the Monte San Lorenzo region (47 35'S, 72 18'W) in the southern Patagonian Andes of Chile and Argentina. This region contains the largest and easternmost glaciers at these latitudes ...
-
(Universidad de Valparaiso, 2013)The macroalga Codium fragile ssp. tomentosoides is characterized by exclusive asexual reproduction through parthenogenesis. We describe the spatial (within thallus) and temporal (seasonal) variability in the abundance of ...
-
(2013)Increasing evidence suggests that, depending on the structural complexity of a plantation, it can act as complementary habitat for insectivore birds and mammals. The magnitude of interactions such as insectivory, in turn, ...
-
(2013)Mediterranean-type ecosystems are one of the most affected environments by habitat loss and fragmentation due to urban development, however only few studies have evaluated the effects of urbanization on the biodiversity ...
-
(2013)It is widely recognized that macroecological patterns are not independent of the evolution of the lineages involved in generating these patterns. While many researchers have begun to evaluate the effect of ancestor-descendant ...
-
(Sociedad Chilena de Quimica, 2012)Mining is one of the most important industrial activities in Chile and there is growing concern on pollution by some mining and metallurgical processes. We have studied the contents of heavy metals in sediments from three ...
-
(2012)The aim of this piece of research was to study the linguistic vitality of Mapudungún in the city of Santiago de Chile, taking into account for its description the (discursive, lexical, writing and communicative) competence ...
-
(2013)We investigate numerically and experimentally the influence of coupling disorder on the self-trapping dynamics in nonlinear one-dimensional optical waveguide arrays. The existence of a lower and upper bound of the effective ...
-
(2013)Nicotine is an agonist of nicotinic acetylcholine receptors (nAChRs) that has been extensively used as a template for the synthesis of α4β2-preferring nAChRs. Here, we used the N-methyl-pyrrolidine moiety of nicotine to ...
-
(2012)Background: Glutamyl queuosine-tRNAAsp synthetase (GluQ-RS) is a paralog of the catalytic domain of glutamyl-tRNA synthetase and catalyzes the formation of glutamyl-queuosine on the wobble position of tRNAAsp. Here we ...
-
(2013)The need to carry out biological conservation outside protected areas requires avoiding, minimizing or mitigating impacts brought about by habitat transformation upon the biota. Usually, forest plantations hold fewer species ...
-
(2013)The dynamics of the collision process of a titanium dimer against a C 20 nanocluster in the bowl configuration is simulated by means ab initio molecular dynamics, focusing our interest on the first steps to synthesize ...
