| As a result of the Uruguay Round (UR), the impact on the international rice market is dramatic.The major U.S. benefit of the UR has been the access to the Japanese market. However, the U.S. share of this import market has been unstable and the share of Korean rice market is nearly zero prior to February 2002. Econometric estimation and Political Preference Function (PPF) approach are incorporated into a game theoretic analysis to analyze U.S. export potential to Japan and Korea. |

| The genus Faika Philipson (Monimiaceae) consists of the single species F. villosa (Kaneh. & Hatus.) Philipson, previously known only from Irian Jaya between the Vogelkop Peninsula and the Cyclops Mts (Philipson, 1986). A recent identification by Renner (of Takeuchi 10349 from the April River; A, LAE) indicates that Faika is also present in Papua New Guinea (PNG). The first author revisited this locality in August 2001 and obtained additional specimens, notes, and photos to document this new record. PNG now has eight genera of Monimiaceae s.s. (excluding Atherospermataceae and Siparunaceae; Renner, 1999): Faika, Kairoa, Kibara, Lauterbachia, Levieria, Palmeria, Steganthera, and Wilkiea. Faika villosa was originally described as Steganthera villosa... |

| Oceans, coasts, and islands are essential to global sustainable development. The oceans, comprising 72% of the earth’s surface, play an essential life-support function without which life on earth would not be possible. 50% of the world’s population lives in coastal areas, and 44 of the world’s nations are small island developing States (SIDS) which are especially dependent on the oceans. Human populations everywhere depend on the oceans for food, energy, transportation, tourism, and other uses. Oceans, coasts, and islands thus do not represent a special or sectoral interest and concern—they are essential to global well-being. Achieving sustainable development in oceans, coasts, and islands thus would go a long way towards achieving global sustainable... |

| Polycystine radiolarians are used to reconstruct summer sea surface temperatures (SSSTs) for the Late Pleistocene-Holocene (600-13,400 C-14 years BP) in the Norwegian Sea. At 13,200 C-14 years BP, the SSST was close to the average Holocene SSST (similar to12degreesC). It then gradually dropped to 7.1degreesC in the Younger Dryas. Near the Younger Dryas-Holocene transition (similar to10,000 C-14 years BP), the SSST increased 5degreesC in about 530 years. Four abrupt cooling events, with temperature drops of up to 2.1degreesC, are recognized during the Holocene: at 9340, 7100 ("8200 calendar years event''), 6400 and 1650 C-14 years BP. Radiolarian SSSTs and the isotopic signal from the GISP2 ice core are strongly coupled, stressing the importance of the... |

| Foi analisado o efeito do predador invertebrado, Chaoborus brasiliensis (Diptera, Chaoboridae), sobre a distribuição espacial dos táxons predominantes da comunidade zooplanctônica de um reservatório tropical raso, lagoa do Nado, explorando as mudanças na sobreposição espacial entre predador e presas durante a migração vertical diária. A comunidade zooplanctônica apresentou uma variada gama de respostas à pressão de predação exercida pelas larvas de Chaoborus. Diversos táxons exibiram MVD (Brachionus falcatus, B. caudatus, B. angularis, Moina micrura, Thermocyclops minutus) e outros em que esse comportamento não foi tão nítido ou não foi detectado (K. cochlearis, K. tropica, K. bostoniensis e náuplios de T. minutus). A maioria dos táxons estudados tiveram a... |

| Invasões biológicas são uma ameaça à manutenção da diversidade biológica, especialmente em fragmentos de hábitat pequenos e isolados. Este trabalho reporta a invasão da Reserva Florestal da Cidade Universitária "Armando de Salles Oliveira" (23º34' S e 46º43' W), um pequeno (10 ha) fragmento florestal, por uma palmeira nativa da Austrália, através da descrição dos padrões espaciais, estrutura de tamanhos e aspectos dinâmicos de sua população. Indivíduos adultos (DAP > 25 cm) se distribuem por grande parte da Reserva. Entre as árvores com DAP > ou = 9,5 cm, em uma área de 2,1 ha, A. cunninghamiana foi a espécie com maior densidade, com 305 indivíduos (22,5% do total). A espécie esteve ausente em locais com histórico recente de perturbação antrópica,... |

| The microencapsulation of recombinant cells, widely used for in vitro high-density cell culture, is a novel and potentially cost-effective method of in vivo heterologous protein delivery, where the protein producing cells are immunologically protected from tissue rejection. We report here a simple, reliable and inexpensive laboratory method to generate calcium alginate microcapsules containing genetically engineered, interleukin-2 expressing, Chinese hamster ovary (CHO) cells. |

| The origins and fates of the Atlantic salinity maximum water (SMW), formed through excess evaporation in the tropics and subtropics of both hemispheres, are studied using monthly mean outputs of a numerical simulation of the world ocean climatological circulation. After defining formation domains from the surface salinity field and the vertical stratification, a Lagrangian technique is used to estimate the formation rates and main pathways in each hemisphere and the role of this water in the framework of the warm water return flow of the meridional overturning cell. Formation rates around 9 and 11 Sv are found in the Southern and Northern Hemispheres, respectively. While the export of the southern SMW from its formation area is realized by the western... |

| Nominal grain and oilseed prices have declined dramatically from the high levels observed in the mid-1990s. As a result, it has been suggested by some industry stakeholders that measures should be taken to limit world crop supplies to raise prices. One such measure is a set-aside program involving a number of participants that would significantly reduce the quantity of land in production over a certain period of time. In fact, the European Union and the United States currently have set-aside programs that, together, already have had a positive effect on crop prices. Set-aside programs could also become relevant if the use of the World Trade Organization blue box is extended to more countries after the next round of negotiations. This analysis focuses on... |
