| Приводятся результаты исследования количественного развития фитопланктона для прибрежных вод Аргентинского архипелага. Материалы собраны в 7-й УАЭ (зимовка 2002 – 2003 гг.) и 10-й УАЭ (сезонные работы 2005 г.). Впервые получены сведения о сезонной динамике количественного развития, видовом разнообразии фитопланктона, выделены доминирующие виды, сроки их массовой вегетации и стадии сукцессии. В водах архипелага обнаружено 126 видов и разновидностей микроводорослей, 73% из которых – диатомовые, 16,6 % - динофитовые. Исследования, проведённые антарктической осенью 2005 г., дополнили список видов на 31 таксон. Наиболее высокие показатели обилия фитопланктона получены для весенне-летнего сезона, когда в октябре наблюдалось «цветение» воды, вызванное мелкими... |

| The aim of this study was to test whether the richness observed and the biomass per trophic group of fish assemblages vary depending on the order (1st and 2nd) of the streams located in three different basins of the Upper Paraná River Basin, Central Brazil. Samples were collected between April and September, 2009, in 27 streams of the Meia Ponte, Piracanjuba and Santa Maria River basins. A total of 4,879 specimens were collected distributed in 59 species and 19 families. The statistical analyses carried out indicate that the observed richness and biomass of omnivore fish were influenced by the interaction of two factors: stream order and basin. The 2nd order streams located in the Santa Maria basin presented significant differences in the observed richness... |

| We characterized the local benthic Chironomidae by analyzing the numerical density, biomass, diversity index of Shannon-Wiener and dominance of larvae in the main channel of the Ivinhema River, in a secondary channel, in five lakes connected to the main channel and in five lakes without connection. Of the 68 taxa identified, Aedokritus sp., Tanytarsus sp., Chironomus strenzkei Fittkau, 1968 and Procladius sp.1 were found in all sampling sites and were considered morphospecies with greater of greatest ecological plasticity. Chironomus strenzkei Fittkau, 1968, contributed with the greatest biomass in the central region of lakes without connection, whereas Aedokritus sp. dominated in the littoral of lakes. The greater values of diversity indices in the... |

| Este trabalho, juntamente com o Documentos 36 (Estudo bibliométrico e análise de patentes acerca da produção de ácidos carboxílicos e álcoois a partir de açúcares - Parte 1: Ácidos carboxílicos) formam o mais completo estudo sobre a utilização da biomassa para a produção de bioquímicos renováveis realizado pela Embrapa Agroenergia. Nesta segunda parte, o tema explorado é a produção de álcoois a partir de fontes renováveis de matéria-prima. Semelhante ao que foi realizado na parte 1, são analisados dados e informações recuperadas em fontes secundárias, especialmente publicações científicas e patentárias, com o objetivo de traçar um panorama da pesquisa científica e aplicada acerca da obtenção de álcoois derivados da biomassa, bem como determinar o cenário... |

| ABSTRACT: In the Cerrado Biome, the internal carbon cycling, the main carbon pools size, and the fluxes intensity between carbon pools are far from to be completely understood. This study presents the main carbon pools and cycling fluxes in terrestrial ecosystems, emphasizing the neotropical savannas. This study will also review literature of internal carbon cycling in the Cerrado. In spite of the science advances, the knowledge of internal carbon dynamics in the Cerrado are scarce. The relation between the carbon pools size and fluxes intensity and the Cerrado's vegetation phytofisionomies, soil gradient, and climate still remains unknown. The carbon pools and fluxes data analysis show that the Cerrado's aerial carbon pools are smaller than the forest... |
