(2008)Odour-mediated signal transduction is a complex process that occurs in the cilia of olfactory sensory neurons. To gain insight in to the molecular organization of the odour transduction machinery, we developed a procedure ...
-
(2009)In agroforestry systems, the effect of shade trees on coffee net photosynthesis (An) has been the object of debates among coffee scientists. In this study, we undertook over 600 coffee An "spot" measurements under four ...
-
(2009)We report four opportunistic field observations of a species of Abrocoma in Polylepis besseri woodlands in Cochabamba Department, Bolivia. These observations sug-gest four significant aspects of Abrocoma sp. natural history: ...
-
(2009)Question: How does the duration of temporary ponds affect the morphological attributes and life-history traits of post-metamorphic amphibians? Organism: The anuran Rhinella spinulosa of the Andes range of central Chile. ...
-
(2009)Background: Morphogenetic events that shape the Drosophila melanogaster embryo are tightly controlled by a genetic program in which specific sets of genes are up-regulated. We used a suppressive subtractive hybridization ...
-
(Sociedad de Biologia de Chile, 2009)Egeria densa Planchon is considered an invasive species in continental aquatic systems in Chile. Its original geographical distribution was limited to the subtropical regions of Brazil, Argentina and Uruguay. Its fast ...
-
(Universidade Federal de Sao Carlos, 2008)The behavior of the termites was analyzed when applying sonic and ultrasonic waves with different frequencies, levels of energy, and waveform to establish the conditions to create a physical barrier to the action of the ...
-
(2009)Determination of fecal steroid metabolites is a noninvasive technique that characterizes the physiological state of organisms without the physiological and psychological stress of handling. Although this technique has many ...
-
(2009)We study the properties of two-color nonlinear localized modes which may exist at the interfaces separating two different periodic photonic lattices in quadratic media, focusing on the impact of phase mismatch of the ...
-
(Optical Society of America (OSA), 2009)We study a waveguide array with an embedded nonlinear saturable impurity. We solve the impurity problem in closed form and find the nonlinear localized modes. Next, we consider the scattering of a small-amplitude plane ...
-
(2009)Pollination is a requisite for sexual reproduction in plants and its success may determine the reproductive output of individuals. Pollinator preference for some floral designs or displays that are lacking or poorly developed ...
-
(2009)The chemical composition of essential oils of five aromatic Asteraceae native of Chile was examined using GC and GC/MS. In the oil of Gnaphalium philippi Cabrera, 25 compounds were identified, with (E)-nerolidol (44.3%) ...
-
(2009)We studied the attraction between Au and Tl in the [AuCl(PH3)2]Tl+ complex using ab initio methodology. This is a hypothetical compound. We found that the changes around the Au-Tl equilibrium distance and in the interaction ...
-
(2009)We analyze the geographic distribution pattern of Chilean amphibian and reptile species between 18°20′S (Arica) to 56°S (Magellanic Area) by the identification of centers of higher richness and endemism and we infer the ...
-
(2009)Marine pelagic copepods must cope with a highly heterogeneous environment in coastal upwelling systems. In addition to spatial and temporal heterogeneity in temperature and food supply, advective forces may strongly influence ...
-
(2008)The structural elucidation of natural products and complex organic molecules relies heavily on the application of proton detected heteronuclear NMR. Among these techniques, the HMBC NMR experiment remains as the most popular ...
-
(Sociedad de Biologia de Chile, 2008)Porphyry Cu-Mo deposits have influenced surface water quality in high-Andes of north-central Chile since the Miocene. Water anomalies may reduce species abundance and diversity in alpine meadows as acidic and metalrich ...
-
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2009)The postembryonic development, consumption and life table parameters of Cydnodromus picanus Ragusa and Phytoseiulus persimilis (Athias-Henriot) were studied at 29.44 ± 1.47 °C and 42.35 ± 5.01% of RH with a photoperiod of ...
-
(2008)Peatlands are globally known as major deposits of fresh water and carbon, affecting the planet's weather and local hydrology; for bearing unique plant and animal species, contributing to biodiversity; and because they ...
-
(2009)Light signals perceived by phytochromes (Phys) and cryptochromes (Crys) play key roles in plant growth and development and in photoperiod dependant process such as flowering, tuberization, seasonal growth cessation and ...
