| Benthic primary production and respiration were investigated at 4 sites representative of the major coastal communities bordering the Sahara Desert in the Banc d'Arguin, Mauritania, Western Africa. These sites correspond to intertidal Zostera noltii beds (270 km(2)), intertidal bare sediments (88 km(2)), subtidal Cymodocea nodosa beds (374 km(2)), and subtidal bare sediments (311 km(2)). At each site, production-irradiance relationships were established in situ in November 2008 and January 2010, and used to calculate daily carbon fluxes for these communities. In intertidal areas, compared to emersion, the gross maximal photosynthetic rates for Z. noltii bed and bare sediment communities were on average 8-and 7-fold higher during immersion, respectively;... |

| Many bacteria biosynthesize structurally diverse exopolysaccharides (EPS) and excrete them into their surrounding environment. The EPS functional features have found many applications in industries such as cosmetics and pharmaceutics. In particular, some EPS produced by marine bacteria are composed of uronic acids, neutral sugars, and N-acetylhexosamines, and may also bear some functional sulfate groups. This suggests that they can share common structural features with glycosaminoglycans (GAG) like the two EPS (HE800 and GY785) originating from the deep sea. In an attempt to discover new EPS that may be promising candidates as GAG-mimetics, fifty-one marine bacterial strains originating from deep-sea hydrothermal vents were screened. The analysis of the... |

| Blackberries have now become a common fruit in marketing outlets, particularly in North America and the European Union. Blackberries have enjoyed expansion due to a combination of factors including improved cultivars, expanded marketing efforts and fruit availability, and an overall increase in berry consumption, especially as fresh fruit, in many areas of the world. It is estimated that cultivated blackberries are grown in excess of 25,000 ha worldwide. World production, and cultivation are commented.The rapid expansion of the blackberry industry has been remarkable. New, higher quality, cultivars, modified production practices and new production regions have all combined to make this crop one that consumers expect to be available fresh year-round in... |

| In an attempt to understand better Brazil's future role in agricultural markets, the authors of this report traveled to Brazil on a fact-finding mission in September 2003. The goal was to get a first-hand impression of Brazil's agricultural sector and especially its future potential. In this report we provide a general description of crop and livestock production, government policies, public and private cooperation, and transportation and biotechnology issues. The most striking observations made during our time in Brazil was the universal sense of optimism expressed by producers, government officials, agronomists, and market analysts about the future growth of Brazilian agricultural production. Does that mean Brazil, as one person suggested, is the... |

| Soybean production in Brazil has grown rapidly in recent years. The objective of this publication is to evaluate the potential impact of Brazilian soybean production on North Dakota and other producers. Brazil, followed by Argentina, is the leading producer in South America. All South American soybean production surpassed the United States during 2002-03. In Brazil, production and yields have grown the fastest in Mato Grosso (Center-West) and other expansion states that have Cerrado land. Soybean costs of production for 2003 harvest are considerably lower in Mato Grosso than in North Dakota and Iowa even when freight costs to Rotterdam are considered, giving them a strong competitive position in the world market. Consequently, Mato Grosso soybean... |

| Uma variedade de milho é um conjunto de plantas com características comuns, sendo um material geneticamente estável. Por essa razão, o agricultor pode reutilizar a semente colhida sem nenhuma perda na produtividade. Tal fato não ocorre quando o agricultor reutiliza sementes colhidas de um híbrido plantado no ano anterior. Nesse caso, há uma queda mínima na produtividade de 20% . Isso se deve à perda do "vigor híbrido. " Esta publicação tem como objetivo orientar a produção de sementes de milho variedade em comunidades rurais. Seguindo essas instruções, os produtores terão sementes melhores, mais produtivas e não precisarão todo ano adquirir novas sementes de milho. |

| O capim setaria (Setaria anceps Stapf ex Massey ou Setaria sphacelata (Schumach.) Moss var. sericea (Strapf Clayton), cujas cultivares mais utilizadas no formação de pastagens no Brasil são Kazungula e, em menor escala, Nandi e Norok, vem despertando um crescente interesse no meio pecuário, pelas suas boas características forrageiras, especialmente pela sua considerável capacidade de crescimento durante boa parte do período seco. Resultados experimentais e observações a nível de fazendas tem confirmado os bons níveis de produtividade e suporte da espécie verificados em outros paises, destacando-a ainda como uma gramínea resistente ao pisoteio e, aparentemente, as cigarrinhas das pastagens. Neste trabalho, são apresentados uma descrição sucinta das três... |
