| A distinctive chert erratic pebble found on the beach at Overstrand, north Norfolk, eastern England, is a Derbyshire screwstone. Such cherts are typical of the Mississippian (Lower Carboniferous) limestones of the southern Pennines (White Peak), over 200 km to the northwest. It was most probably transported by fluvial or glacial action during the Pleistocene and was recently disinterred by coastal erosion. The most diagnostic feature of screwstone cherts are the included mouldic crinoid ossicles, particularly columnals. Columnals of the monobathrid camerate crinoid Megistocrinus? globosus? (Phillips) are described from this screwstone; these have a circular outline, central pentagonal lumen and a raised perilumen. The uncertainty of the identification is... |

| A produção da farinha de mandioca no Território da Cidadania do Vale do Juruá, Acre, contempla os municípios de Cruzeiro do Sul, Mâncio Lima, Rodrigues Alves, Marechal Thaumaturgo e Porto Walter. Esses municípios são reconhecidos pela grande produção de farinha, obtida por método artesanal em unidades familiares denominadas casas de farinha. O modo tradicional de produção de farinha dessa região, herdado por gerações, confere ao produto qualidade notória. A preferência dos consumidores pela farinha de mandioca de Cruzeiro do Sul, há décadas, tornou-a um produto potencial para Indicação Geográfica na modalidade Indicação de Procedência (IP). A IP reconhece a região em que a farinha é produzida, a forma peculiar de fabricação do produto e oferece ao... |

| The Okinawa Trough is a natural laboratory for the study of later Quaternary land-ocean interaction and paleoenvironmental changes. In this study we reconstruct the evolution of clay mineral assemblages in Core DGKS9604 retrieved from the central Okinawa Trough. Illite dominates the clay mineral compositions, with average contents above 60%. Clay mineral evolution since 28 ka is closely related to changes in sediment provenance and paleoenvironment. Sea level rise and the strength of the Kuroshio Current control the dispersal and deposition of clays on the East China Sea shelf and in the Okinawa Trough, and thus, determine the clay mineral compositions in the core sediments. During the late last glacial period (28.0-14.0 ka), the paleo-Changjiang River... |

| We introduce a methodology for determining the transport distance of subglacially comminuted and entrained sediments. We pilot this method on sediments from the terminal margin of the Baltic Ice Stream, the largest ice stream of the Fennoscandian Ice Sheet during the Last Glacial Maximum. A strong correlation (R2 = 0.83) between the εNd and latitudes of circum-Baltic river sediments enables us to use εNd as a calibrated measure of distance. The proportion of subglacially transported sediments in a sample is estimated from grain size ratios in the silt fraction (<63 μm). Coupled εNd and grain size analyses reveal a common erosion source for the Baltic Ice Stream sediments located near the Åland sill, more than 850 km upstream from the terminal moraines.... |

| The invasive behaviour of sourgrass (Digitaria insularis) in cultivated areas is due to its strategy of aggressive regeneration, which is based on seed germination. Knowledge of the physiological ecology of this species can contribute to the development of management and control strategies. The aim of this research was to understand the effects of provenance, temperature and light on the germination of sourgrass seeds collected in the Brazilian state of São Paulo in the cities of Americana, Botucatu and São José do Rio Preto and in the state of Paraná in the city of São Miguel do Iguaçu. The seeds were left to germinate at temperatures of 15, 25, 35 and 45 °C, both with and without light. The number of normal seedlings was recorded daily from seven to 60... |

| O comportamento silvicultural de doze especies/procedencias de Eucalyptus foi estudado em tres regioes bioclimaticas do Estado de Minas Gerais: Uberaba, Paraopeba e Vicosa. As avaliacoes periodicas mostraram maiores incrementos em altura e diametro nas fases iniciais de crescimento, ate os 4,5 anos de idade, quando entao os incrementos foram menores, possivelmente por causa da competicao entre plantas e disponibilidade de nutrientes em funcao da idade. No periodo compreendido entre 6,5 e 7,5 anos verificou-se uma maior velocidade no crescimento em altura e diametro nos tres locais, relacionada com o regime de precipitacao. Nas avaliacoes conduzidas aos 7,5 anos, foram verificadas, de modo geral, diferencas significativas entre as especies, dentro de locais... |
