Biogeochemical parameters of sea water and bottom sediments near the Curieuse Island (Seychelles Islands)

Biogeochemical reef studies carried out in 1981 and 1984 found low concentration of total natural and anthropogenic hydrocarbons in inshore waters. Detection of lignin in marine and bottom sediments indicates that the land has major effect on makeup of organic matter there. Comparison of compositions of organic matter in sea water, suspended matter and bottom sediments indicated that it was altered rapidly by the reef community. Thus, in the inshore zone of the island, runoff from the land is important in supplying nutrients to the reef ecosystem alongside with transport of nutrients by deep waters. Concentrations of nutri¬ents (N, P) in the inshore zone are higher than in waters of the tropical part of the ocean. Nitrogen is the limiting element in development of phytoplankton in the inshore zone.

(Table 1) Lithological and organic-geochemical compositions of bottom sediments from the Southwestern Indian Ocean (Mozambique Basin)

Geochemical changes in organic matter of bottom sediments from the Mozambique Basin at the river-sea barrier from the mouths of the Zambezi and Limpopo rivers toward the pelagic zone are discussed. Changes in bitumen, hydrolyzable material, humic acids, amino acids, n-alkanes, and polycyclic aromatic compounds resulting from genetic and diagenetic factors are described. This information is significant for paleoceanology reconstructions and for knowing ways of organic matter transformation into fossil forms.

Carbon dioxide assimilation rate, gas and ion composition in samples, and bacterial production of organic matter within and above the Broken Spur and TAG hydrothermal fields, Mid-Atlantic Ridge

Rate of CO2 assimilation was determined above the Broken Spur and TAG active hydrothermal fields for three main ecosystems: (1) hydrothermal vents; (2) 300 m near-bottom layer of plume water; and (3) bottom sediments. In water samples from warm (40-45°C) vents assimilation rates were maximal and reached 2.82-3.76 µg C/l/day. In plume waters CO2 assimilation rates ranged from 0.38 to 0.65 µg C/l/day. In bottom sediments CO2 assimilation rates varied from 0.8 to 28.0 µg C/l/day, rising up to 56 mg C/kg/day near shrimp swarms. In the most active plume zone of the long-living TAG field bacterial production of organic matter (OM) from carbonic is up to 170 mg C/m**2/day); production of autotrophic process of bacterial chemosynthesis reaches about 90% (156 mg C/m**2/day). Thus, chemosynthetic production of OM in September-October is almost equal to that of photosynthetic production in the oceanic region. Bacterial production of OM above the Broken Spur hydrothermal field is one order lower and reaches only 20 mg C/m**2/day.

Systematic expression profiling of the mouse transcriptome using RIKEN cDNA mircoarrays

The number of known mRNA transcripts in the mouse has been greatly expanded by the RIKEN Mouse Gene Encyclopedia project. Validation of their reproducible expression in a tissue is an important contribution to the study of functional genomics. In this report, we determine the expression profile of 57,931 clones on 20 mouse tissues using cDNA microarrays. Of these 57,931 clones, 22,928 clones correspond to the FANTOM2 clone set. The set represents 20,234 transcriptional units (TUs) out of 33,409 TUs in the FANTOM2 set. We identified 7206 separate clones that satisfied stringent criteria for tissue-specific expression. Gene Ontology terms were assigned for these 7206 clones, and the proportion of 'molecular function' ontology for each tissue-specific clone was examined. These data will provide insights into the function of each tissue. Tissue-specific gene expression profiles obtained using our cDNA microarrays were also compared with the data extracted from the GNF Expression Atlas based on Affymetrix microarrays. One major outcome of the RIKEN transcriptome analysis is the identification of numerous nonprotein-coding mRNAs. The expression profile was also used to obtain evidence of expression for putative noncoding RNAs. In addition, 1926 clones (70%) of 2768 clones that were categorized as unknown EST, and 1969 (58%) clones of 3388 clones that were categorized as unclassifiable were also shown to be reproducibly expressed.

Alternativas botánica, biológica y química para el manejo de piojo del tomate (Halticus sp) (Hemíptera: Miridae) y mosca blanca (Bemisia tabaci, Gen) (Hemiptera: Aleyroridae) en el cultivo de tomate (Solanum lycopersicum L.), bajo condiciones de casa malla.

El piojo del tomate (Halticus sp.) y la mosca blanca (Bemisia tabaci) son los principales agentes de daño, causantes de problemas fitosanitarios severos para los productores de tomate (Solanum lycopersicum, L), bajo condiciones de casa malla. Esta plaga provoca importantes pérdidas económicas, disminuyendo así los rendimientos al afectar la calidad de los frutos lo cual incide en mayores costos de producción. En base a esta problemática en el CEVAT (Centro de Experimentación y Validación de Tecnologías), UNA, se realizó un estudio en el período comprendido entre los meses de Septiembre 2015 a Enero 2016, con el objetivo de evaluar insecticidas biológico, botánico y químico contra el piojo del tomate y mosca blanca. Los productos evaluados fueron: Engeo, Madero Negro y Metarhizium anisopliae. Las variables evaluadas fueron: número de Halticus sp por planta, incidencia del daño por Halticus sp por planta, numero de mosca blanca por planta, incidencia del daño de virosis por planta, severidad del daño de virosis por planta. De los tratamientos evaluados, el menor promedio de piojo del tomate por planta lo presentó el tratamiento Engeo y de igual manera en mosca blanca, seguido de madero negro. El menor porcentaje de incidencia y severidad lo presentó el tratamiento Engeo en comparación con los demás tratamientos evaluados. El análisis económico realizado determinó que los tratamientos que presentaron los mejores rendimientos fueron Engeo con 18,156.25 kg/ha, seguido por Madero Negro con 16,891 kg/ha y Metarhizium anisopliae que obtuvo 14,797 kg/ha. Engeo presentó el mayor beneficio neto con 16,642.92 US$/ha, seguido por Madero Negro con 15,240.86 US$/ha. En el análisis de la tasa de retorno marginal resultó que el tratamiento Madero Negro es el que obtuvo la mejor tasa de retorno marginal con 6,307.36 % es decir 63.07 US$ por cada dólar invertido.
