G. galatheanum , like many photosynthetic dinoflagellates, contains high amounts of n-3 long-chain-polyunsaturated fatty acids (LC-PUFA) such as docosahexaenoic acid (DHA, 22:6n-3) and the hemolytic toxic fatty acid 18:5n-3. We hypothesize that a benefit of phagotrophy in G. galatheanum is the acquisition of precursor linolenic acid (18:3n-3) that fuels LC-PUFA synthesis. Phototrophs grew at 0.37 d Ϫ 1 , while mixotrophs grew at 0.40 d Ϫ 1 with a feeding rate of 0.62 d Ϫ 1. Photosynthesis was lower in mixotrophs (3.7 pg C cell Ϫ 1 h Ϫ 1) than phototrophs (4.9 pg C cell Ϫ 1 h Ϫ 1). DHA levels were higher in mixotrophs [3.7 (ϩ / Ϫ 0.11) pg cell Ϫ 1 ] than phototrophs [3.0 (ϩ / Ϫ 0.16) pg cell Ϫ 1 ] and prey [0.4 (ϩ / Ϫ 0.01) pg cell Ϫ 1 ]. 18:5n-3 levels [1.7 (ϩ / Ϫ 0.03) pg cell Ϫ 1 ] were similar in phototrophs and mixotrophs. An intermediate in n-3 LC-PUFA synthesis, 20:4n-3, accumulated in mixotrophs [0.6 (ϩ / Ϫ 0.27) pg cell Ϫ 1 ] relative to phototrophs (not detected) and prey [0.03 (ϩ / Ϫ 0.002) pg cell Ϫ 1 ]. Low ratios of linolenic acid to DHA in phototrophic G. galatheanum (0.14) relative to mixotrophic G. galatheanum (0.29) and prey (2.14) are consistent with substrate limitation of LC-PUFA synthesis in phototrophs. Accumulation of 20:4n-3 suggests incomplete conversion of linolenic acid to DHA, possibly due to conditions in batch culture. We conclude that precursors for n-3 LC-PUFA biosynthesis in G. galatheanum may be acquired through ingestion of S. major , and may partially control feeding/photosynthesis in mixotrophic populations.

The data sample corresponds to an integrated luminosity of 4.98 fb −1 of proton-proton collisions at √ s = 7 TeV collected with the CMS detector at the LHC in 2011. The number of observed events is consistent with predictions for standard model processes. Lower limits on the mass of the gluino in supersymmetric models are determined.

Su enfoque puede ser catalogado como etnohistórico, vale decir, con base en documentación escrita de época colonial, que le llevó inclusive a anticipar la tesis sobre el control vertical de pisos ecológicos que medio siglo más tarde formulará John Victor Murra. Palabras claves: Rómulo Cúneo-Vidal, etnohistoria andina, Arica, Tacna, verticality. The purpose of this study is to highlight the intellectual legacy of Rómulo Cúneo-Vidal, a scholar from Arica, whose work represents the study of the ethnic groups of the Arica-Tacna region that was ahead of his time. His studies can be defined as an ethnohistoric approach because he utilized all sources of colonial documents which allowed him to anticipate the model of verticality that was formulated 50 years later by John V. Murra.

Los valores mkimos de biomasa se encontraron en mayo (47.57 gr/m2, peso seco) y mfnimos en diciembre (0.11 gr/m2). En cada muestreo se tomaron plantas para analizar el estado reproductivo de la especie, not8ndose formación de carposporas a fmales de mayo y la ezpulsión de las mismas en los meses subsecuentes. El ejemplar desaparece por completo durante invierno y reaparece en marzo. Dadas las condiciones ambientales del Brea de estudio y el comportamiento sobre la fenologfa y biomasa encontrados esperarfamos detectar posrbles diferencias con las poblaciones localizadas hacia el norte y sur de la bah fa.

The risk of having low-birth-weight babies is measured using nutritional indexes based on women's height, weight, and age group. Data are from a survey of 69,655 women aged 15-49 in the province of Havana. (SUMMARY IN ENG AND FRE)
