| Development of the immature stages of Culex (Culex) saltanensis Dyar (Diptera, Culicidae) under laboratory conditions. Culex (Culex) saltanensis Dyar, 1928 is becoming frequent and abundant in natural and artificial breeding sites in urban and rural areas of Brazil. This study contributes to the knowledge of the biology of a Brazilian strain of C. saltanensis. The development of specimens reared individually or grouped was observed. The study was conducted at a constant temperature of 27 ± 2°C, 14L:10D photoperiod and 80 ± 5% relative humidity. The immature stages were observed every 6 hours until adult emergence, which occurred in 12.29 days among individually reared specimens and in 13.12 days among group-reared specimens. Egg rafts for the experiment... |

| O experimento teve por objetivo avaliar o efeito do sistema de criação e da época do ano, sobre o desempenho e qualidade da carne de frangos de corte. Foram estudadas 524.000 aves da linhagem comercial Cobb 500, distribuídas em três galpões com diferentes sistemas de automatização, durante as quatro estações do ano. O delineamento foi inteiramente casualizado, com esquema fatorial 3 x 4 (tipo de galpão x época do ano). Foram utilizadas rações do sistema integrado, cama de palha de arroz, e as aves foram abatidas em um frigorífico aos 43 dias de idade. Foram avaliados os dados de desempenho (consumo de ração, ganho de peso diário, conversão alimentar e mortalidade), com dados fornecidos pelo sistema integrado. Também, foram avaliados os defeitos nas... |

| ABSTRACT The objective of this study was to evaluate the impact of farrowing and mortality rates on inbreeding levels and genetic gain through data simulation. Data came from two real populations A and B, composed of Pietrain and Landrace breed pigs, respectively. To generate the simulated populations, a Fortran-language simulator was developed using the (co)variances of the breeding values and productive and reproductive information obtained from populations A and B, as well as restrictions on mating and animals selected per generation. Two data files were created. The first contained the pedigree of the previous 10 years, with 21,906 and 251,343 animals in populations A and B, respectively. The second included the breeding values for age, backfat... |

| Entre julio de 2009 y diciembre de 2010 se desarrolló el monitoreo de la flota de botes de fibra de vidrio dirigida a la captura de peces pelágicos grandes con enmalle de superficie de 4 y 5” de ojo de malla, que opera en la caleta pesquera de Sta. Rosa a través de observadores científicos a bordo. Se analizó la información sobre la captura incidental de 537 lances de pesca efectuados entre 01°00,00-03°23,00 S y desde 080°50,00-082°30,00 W (35 y 95 millas náuticas frente al perfil costero). Se estableció que las redes utilizadas operaban adecuadamente y que los porcentajes de incidencia de tortugas y mamíferos marinos en la sección de los flotadores es del 82,4 y 69,8 %, respectivamente. Los índices de captura más elevados por grupos fueron para:... |

| A production monitoring network focused on the blue mussel Mytilus edulis, was developed at the Charentais sounds' geographic level to assess the spatial and temporal variability of the mussel production. Similarly to the oyster growth monitoring network REMORA, an homogeneous and calibrated mussel population (L = 35.5 mm, TW = 3.35 g) was distributed into six rearing sites, representative of the sounds production. The rearing technics were compared and intercalibrated with previous growout facilities used for preliminary trials (round bags-oyster bags). The monitoring was based upon biometric and biochemical measurements on a 3 month and monthly basis, for ail and 3 sites respectively. The mortality rates showed a significant spatial and temporal... |

| Thiis report aims to study the oyster Crwsosrrea gigas growth and production over a 12 years time' s span in the bay of Marennes-DIeron. Results of 12 years of oyster growlh did not show any significant oyster biological productivity decrease, nor trend. ln contrast, annual growth showed a large variability, which will be correlated with environmental conditions. Moreover, annual growth variability was greater than the variability due to site location,. besides the Ronce experimental site. The later, located in the south west part of the bay of Marennes-Dleron, has been the leading oyster growth site since 1989. The annual shell growlh variabiliry was greater than oyster dry meat weight fluctuation . Both 1990 and 1991 years were characterized by the... |

| This study evaluated the influence of nitrogen levels (N) and plant density (D) on the tillering dynamics of Tanzania guinea grass (Panicum maximum Jacq.). Treatments were arranged in a completely randomized block design with 12 treatments and two replicates in a factorial scheme (4 × 3) with four levels of N (0, 80, 160 or 320 kg ha-1 N) and three plant densities (9, 25, and 49 plant m-²). Higher number of tillers was observed in the treatment with 9 plants m-² and under higher levels of N, especially in the second and third generations. Still, the N influenced quadratically the appearance rate of basal and total tillers, which were also affected by plant density and interaction N × D. However, the appearance rate of aerial tiller was not influenced by... |
