(2013)Background: Xanthophyllomyces dendrorhous is a basidiomycetous yeast that is relevant to biotechnology, as it can synthesize the carotenoid astaxanthin. However, the astaxanthin levels produced by wild-type strains are ...
-
(2013)The impacts of exotic plants on the pollination and reproductive success of natives have been widely reported; however, in spite of its importance for the invasive process, the role of native plants in the pollination and ...
-
(Elsevier B.V., 2013)We have observed by means of scanning tunneling microscopy (STM) moiré patterns corresponding to the rotation of one graphene layer on HOPG surface. These moiré patterns were characterized by rotation angle and extension ...
-
(Elsevier Ireland Ltd, 2013)Codons expanded by a silent position (quadruplet or tetracodons) may solve the conundrum that at life's origins, the weak tricodon-anticodon interactions could not promote translation in the absence of complex ribosomes. ...
-
(2013)Weakly bonded Cadmium clusters have, even for small number of atoms, many isomers that are stable structures. Before any attempt to use ab initio calculations on these clusters, a limited set of good possible stable isomers ...
-
(2013)How much do ecosystems contribute to the wellbeing of rural populations in developing nations? In this article we provide an answer to this question through an eco-social study of two provisioning ecosystem services (wood ...
-
(2013)Quaternary glaciations in Antarctica drastically modified geographical ranges and population sizes of marine benthic invertebrates and thus affected the amount and distribution of intraspecific genetic variation. Here, we ...
-
(2013)Loxoscelism is a health problem caused by the bite of spiders of the genus Loxosceles. In Chile all cases are attributable to Loxosceles laeta. It has been suggested that the spitting spider Scytodes globula may be a ...

(2012)In April 2009, at the Salar de Punta Negra (24°35'S, 68°58'W) in the Antofagasta Region of northern Chile, we quantified the composition, diversity, and size of diatoms, the only consumed prey by both adults and nestlings ...
-
(Verlag der Zeitschrift fur Naturforschung, 2013)The relative lack of specificity of atropine as a competitive antagonist of muscarinic receptors is a frequent cause of undesirable parasympathetic side effects. Consequently, new tropane alkaloids with potentially greater ...
-
(2012)GLUT4-containing vesicles cycle between the plasma membrane and intracellular compartments. Insulin promotes GLUT4 exocytosis by regulating GLUT4 vesicle arrival at the cell periphery and its subsequent tethering, docking, ...
-
(2013)We describe the songs and courtship displays of three closely related hummingbirds, the Peruvian Sheartail (Thaumastura cora), Oasis Hummingbird (Rhodopis vesper), and the endangered Chilean Woodstar (Eulidia yarrellii). ...
-
(2013)A small, new species of gerbil rodents of the genus Eligmodontia from the southwestern dunes of the Atacama Desert in northern Chile is described; the genus had not been reported for this western lowland region. Our ...
-
(2013)The evolution and functions of avian and mammalian antipredator calls are well understood, which contrasts with a lack of progress in reptiles. Here, we present the first investigation of the functions of a distress call ...
-
(2013)Animal translocation is a popular tool in wildlife management. It is frequently used to solve human-animal conflicts and recently has been applied as a mitigation tool when animals inhabit land desired for development. ...
-
(Verlag der Zeitschrift fur Naturforschung, 2013)The extracts of several plants of Central Chile exhibited anti-Trypanosoma cruzi trypomastigotes activity. Most active extracts were those obtained from Podanthus ovatifolius, Berberis microphylla, Kageneckia oblonga, and ...
-
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2013)Guanaco (Lama guanicoe), the only native ungulate of Tierra del Fuego, uses the forests more extensively after the introduction of sheep. It is presumed that the regeneration of lenga (Nothofagus pumilio) is hampered by ...
-
(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 ...
-
(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 ...
