| Con el objetivo de determinar la factibilidad de reactivar la ostricultura al Norte de Villa Clara, Cuba, se realizaron dos cruceros de investigación en febrero y mayo de 2006, meses de seca y lluvia respectivamente. La temperatura del agua presentó valores entre 24,8 y 28,8˚ C; la salinidad mostró valores extremos entre 37 y 39,5; el oxígeno disuelto entre 4,62 y 6,34 mg/L; la transparencia del agua de 45 a 90%; la demanda química de oxígeno presentó extremos entre 1.48 y 3.84 mg/L, y el pH entre 7,98 y 8,28. El fitoplancton presentó variaciones espaciales entre las concentraciones de células de 0,2 a 0,9 x 106 cel/L, siendo las diatomeas el grupo más representativo; el género que mayor abundancia presentó fue Pseudonitzschia sp. A partir de... |

| To help integrated natural resource management (INRM) research "deliver the goods" for many of the world's poor over a large area and in a timely manner, the authors suggest a problem-solving approach that facilitates the scaling out of relevant agricultural practices. They propose seven ways to foster scaling out: (1) develop more attractive practices and technologies through participatory research (2) balance supply-driven approaches with resource user demands, (3) use feedback to redefine the research agenda, (4) encourage support groups and networks for information sharing, (5) facilitate negotiation among stakeholders, (6) inform policy change and institutional development, and (7) make sensible use of information management tools, including models... |

| Tanzanian researchers of the on-going SAREC/Sida-sponsored project on Human Responses and Contribution to Environmental Change (HRAC) have focused their research on a narrow strip of the central coast of Tanzania. The area under investigation is specifically between Kisiju to the north and the Rufiji Delta to the south. Survey work was also extended to the off-shore islands including Kwale, Koma and Mafia. The preliminary intention was to look for sites that could provide light to the whole question of environmental change and its human contribution. |

| Uma agricultura intensiva e permanente depende muito do equilibrio entre perdas e ganhos de nutrientes. Os ganhos sao representados pela adubacoes quimicas e organicas e incorporacao da resteva, e as perdas, pelo cultivos, lixiviacao, volatilizacao e erosao. A erosao nao e seletiva quimicamente, nao produzindo concentracoes diversificadas de nutrientes entre o sedimento e o solo que o formou (tabela 1). A selecao ocorre no maior arraste da materia organica e das particulas mais finas do solo, que sao as armazenadoras dos nutrientes. Os menores teores de nutrientes no tratamento solo descoberto devem-se ao fato de que este recebeu apenas adubacao corretiva de P e K, alem da calagem, em 1977, tendo sido mantido sem vegetacao desde entao e preparado todos... |

| During the rainy season of the ecuadorian coast (march 2012) in the study area including two environmental: Marine area and estuarine area. Were identified in Caraquez Bay the following species of benthic foraminifera: Bulimina pulchella, Cibicidea aknerianus, C. bertheloti, F. boueana, Elphidium articulatum, F. typical, Nonion pizarrense, Quinqueloculina lamarckiana, Rotalia beccarii, Triloculina globulosa, y Uvigerina incilis. These species correspond to the Pananmian zoogeographic province proposed by Boltovskoy (1965) and confirmed by Boltovskoy and Gualancañay (1975, 1986). |

| Le Gabon est situé en Afrique centrale avec une façade atlantique . Il est limité au Nord par le Cameroun, au Nord-ouest par la Guinée Equatoriale, à l’Est et au Sud par le Congo. La zone économique exclusive (ZEE) a une surface de 213.000 Km². elle est plus vaste que celle de Sao-Tomé et Principé, pays insulaire voisin (160.000 Km²). La façade maritime à une longueur de 750 Km , de Coccobeach à Ndindi. La largeur moyenne du plateau continental est de 60 Km, soit une surface à peu-près de 40.600 Km² de la côte à l’isobathe de 200 mètres. Ce plateau se termine par un talus peu abrupt, d’une longueur de 750 Km et d’une superficie de 11.200 Km² entre 200 et 800 mètres de profondeur.... |

| The seasonal changes of heat and salt storages in the offshore water of the Red Sea were studied using a historical data collected from different cruises during the period from 1924 to 1998. The heat storage within water column of different depths exhibits a seasonal variability. The heat storage is low during winter and high during summer. Also, the heat storage increases from north to south. The maximum values of heat storage are found in the southern central part of the Red Sea. It reached about 29.9x109 J/m2 within the water column of 300m depth. The seasonal change of heat storage from the annual mean is negative during winter and spring, while it is positive during summer and autumn. It has higher values during winter and summer, while its value... |
