(Blackwell Publishing Ltd, 2014)The amphibian genus Telmatobius is a diverse group of species that inhabits the Andes. This study analysed the phylogenetic relationships of 19 species described from the central Andes of Chile and Bolivia, and 12 undescribed ...
-
(Allen Press Publishing Services, 2014)In clonal macroalgae, evidence of guerrilla and phalanx growth strategies has been related to a differential response due to a heterogeneous habitat. However, some species of the green algal genus Codium may exhibit different ...
-
(Sociedad Chilena de Quimica, 2014)The crystalline structure of spinels is extremely flexible due to the presence of several sublattices in which the cations can be distributed and localized in different crystallographic sites depending on their sizes, ...
-
(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 ...
-
(Paleontological Society, 2014)We present new records of chondrichthyans recovered from strata of Maastrichtian age of the López de Bertodano Formation, Seymour (=Marambio) Island, and from levels of latest Campanian age of the Santa Marta Formation, ...
-
(John Wiley and Sons Ltd, 2014)Host plants are used by herbivorous insects as feeding or nesting resources. In wood-boring insects, host plants features may impose selective forces leading to phenotypic differentiation on traits related to nest construction. ...
-
(2014)It has been suggested that respiratory stress is involved in the mechanism underlying the dormancy-breaking effect of hydrogen cyanamide (H2CN2) and sodium azide in grapevine buds; indeed, reductions in oxygen levels ...
-
(Kluwer Academic Publishers, 2014)Biogas must be pretreated before its use; thus, both physical and chemical methods have been implemented to remove the fuel's principal pollutants (CO 2and H2S). Additional removal methods that use microorganisms' biological ...
-
(Elsevier Inc., 2014)We consider an evolution algebra which corresponds to a bisexual population with a set of females partitioned into finitely many different types and the males having only one type. We study basic properties of the algebra. ...
-
(Elsevier, 2014)To increase our understanding about the mode of toxic action of organophosphorus pesticides in earthworms, a microcosm experiment was performed with Aporrectodea caliginosa exposed to chlorpyrifos-spiked soils (0.51 and ...
-
(Japan Society for Analytical Chemistry, 2014)This study demonstrates the first use of polydimethylsiloxane (PDMS) immobilized on a rotating disk for the extraction of copper from aqueous matrices and its subsequent direct determination by solid phase UV-Visible ...
-
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2014)Sclerophyllous shrubs and forests are predominant in semiarid Central Chile and have a long history of degradation by fire, cultivation, firewood extraction and grazing. The aim of this study was to compare the amount and ...
-
(Blackwell Publishing Ltd, 2014)In some archaea, the phosphorylation of glucose and fructose 6-phosphate (fructose 6P) is carried out by enzymes that are specific for either substrate and that use ADP as phosphoryl donor. In the hyperthermophilic archaeon ...
-
(Kluwer Academic Publishers, 2014)A genome of a living organism consists of a long string of symbols over a finite alphabet carrying critical information for the organism. This includes its ability to control post natal growth, homeostasis, adaptation to ...
-
(Wiley-VCH Verlag, 2014)New solid solutions Cu2MnxFe1-xSnS4 were prepared by direct combination of the corresponding elements at 850°C. The crystal structure of Cu2Mn0.4Fe0.6SnS4 was determined by single-crystal X-ray diffraction. This phase is ...
-
(Academic Press, 2014)A postcranial specimen from the lower Maastrichtian levels of the Conway Formation, Middle Waipara River, North Canterbury, New Zealand shows clear elasmosaurid affinities, based on the articular faces, with a ventral ...
-
(Sociedad Espanola de Microbiologia, 2013)Decreasing quality of forest habitats is among the major factors leading to a loss of epiphytic lichen diversity. However, there is little information about how this factor influences the diversity of terricolous lichens, ...
-
(Sociedad Chilena de Quimica, 2013)Twenty six compounds were identified by GC-MS analysis from culture broth of six Macromycetes growing in subantarctic forests in southern Chile: Mycena hialinotricha, Collybia butyracea, Inocybe geophylla, Entoloma nubigenum, ...
-
(Escuela de Ciencias del Mar, 2014)During April-May 2004 the Cruces River wetland ecosystem, located in Valdivia (40°S), southern Chile, was described as shifting from a clear water regime, dominated by the exotic macrophyte Egeria densa, to turbid waters ...
-
(Chinese Academy of Sciences, 2014)Due to the higher energy requirements of birds during winter, it is predicted that the activities of metabolic enzymes (e.g., citrate synthase, CS and cytochrome C oxidase, COX) should increase in tandem with increases in ...
