| Este texto teórico aborda os desafios de a Agroecologia se consolidar como um campo científico, visto que muitos pesquisadores envolvidos em sua temática requerem para ela o status de Ciência, ao mesmo tempo em que a sua postura epistemológica questiona severamente os paradigmas vigentes no campo científico. Aqui se defende que a Agroecologia pertence também ao campo científico, não negando que ela possa pertencer a outros campos, e que esse pertencimento é estratégico para evitar o seu desvirtuamento. A partir disso remete ao funcionamento dos campos científicos na busca de elementos que auxiliem a Agroecologia a superar as críticas, marginalizações e preconceitos de uma nova ciência que deseja estabelecer os seus novos paradigmas. |

| O artigo analisa as estratégias de 03 redes de cooperativas que trabalham com leite no Território Oeste de Santa Catarina, verificando sua aproximação com princípios e práticas agroecológicas. Foram estudadas as redes Aurora, Terra Viva e Ascooper, analisando documentos e realizando entrevistas com suas principais lideranças. A agricultura familiar está na base organizacional das 03 redes e ela adotou a produção de pastagem como a principal forma de alimentação dos animais, o que representa uma inovação coletiva no território, ocorrida de forma difusa, sem liderança de nenhum ator social específico. Além da produção à pasto, a Terra Viva e a Ascooper avançaram com a fitoterapia e a homeopatia na sanidade dos animais, mostrando maior ênfase na construção de... |

| Modelling of fish movement behaviour within a heterogeneous marine environment is a challenging but also key issue for understanding the effect of environmental factors and climatic change on fish processes (growth, distribution, mortality, reproduction). Fish movement models have the capability to encompass the combined effect of environment and empirical knowledge of fish individuals as energy requirements, known preys and predators, swimming capacities into a unified framework. Following an Individual Based Model (IBM) approach, a fish movement model has been developed to simulate the active movement of adult anchovy in the Bay of Biscay (BoB) in response to the spatio-temporal variations of both biotic and abiotic factors, as well as its internal... |

| This paper offers a theoritical and empirical model of ecosystem-based fishery management. A multi-species and multi-fleet integrating Lotka-Volterra trophic dynamics as well as production and profit assessments is developed and applied to the coastal fishery of French Guiana. This small-scale fishery constitutes a challenging example with high fish biodiversity, several non-selective fleets and a potentially increasing local food demand due to demographic growth. The dynamic model is calibrated with 13 species and four fleets using monthly catch and effort data from 2006 to 2009. Several contrasted fishing scenarios including status quo, total closure, economic and viable strategies are then simulated. They are compared from the viewpoints of both... |

| Background: The melanocortin-4 receptor gene (MC4R) plays an important role in regulating food intake and body weight in mammals. In the present study, we identified the MC4R gene in native Korean brown, brindle, and black cattle by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP), and investigated its association with economic traits. A total of 413 cattle from the three breeds were tested for backfat thickness, carcass weight, longissimus muscle area, and marbling score, and statistical data were analyzed using the SAS program. Results: The C allele had the highest frequency in brown and brindle cattle, and the G allele frequency was highest in black cattle. The C1069G SNP was significantly (p < 0.05) associated with only... |

| The external jugular vein is increasingly being utilized as the recipient vein in head and neck free tissue transfers, and for cannulation in order to conduct diagnostic procedures or intravenous therapies. The variations in the patterns of its course, and knowledge of them, are therefore important. We report on a unique and previously non-described unilateral fenestration and duplication of the external jugular vein found during the neck dissection of a 77-year-old female cadaver. Embryological evaluation and clinical implications of the anomaly are described. Clinicians and surgeons performing neck vascular or reconstructive surgery should be aware of this variation of the external jugular vein in the hope of preventing inadvertent injury. |

| The Hymenoptera laboratory of the Museu de Zoologia da Universidade de São Paulo (MZSP) houses one of the most representative collections of Neotropical ants worldwide. This is due to the wide geographical distribution of its specimens, and also because of the comparatively large number of types and taxa represented. The catalogue, following the general recommendations of the International Code of Zoological Nomenclature, lists types of the tribe Cephalotini deposited in the collection of MZSP; also providing information regarding labels, original publications, state of conservation of specimens, taxonomic status of listed species, and their current classification when different from the original. An index for the listed taxa is also provided. In total,... |
