| Insects are important environmental bioindicators, due to the species diversity and wide range of habitats occupied. The present study evaluated the temporal variation in composition and abundance of soil insects in an urban forest fragment in the municipality of Toledo, in the state of Paraná, by analyzing their abundance and seasonality. Monthly samplings were conducted between August 2011 and July 2012 at four sampling sites within the fragment. At each site, three pitfall traps remained exposed for 48 hours. Captured insects were fixed in alcohol, sorted and identified. Throughout the study period, we captured 11,568 insects from 11 orders and 35 families. Coleoptera was the richest order (12 families), followed by Diptera and Hemiptera (5),... |

| Este trabalho apresenta teoria e análise de dialelos parciais, usando dados dos pais e das gerações F2. A metodologia está fundamentada nos métodos propostos por Hayman, em 1954 e 1958. A análise dialélica possibilita a caracterização dos sistemas poligênicos em estudo, por meio da estimação de componentes genéticos e não genéticos de variação e de parâmetros genéticos, em relação a cada grupo de pais ou a cada pai, dependendo do componente de variação ou parâmetro de natureza genética. Os parâmetros genéticos são: médias dos produtos das freqüências de alelos, graus médios de dominância, proporções médias de genes dominantes e recessivos nos pais, direção de dominância e herdabilidade. É apresentada uma análise dialélica com feijoeiro |

| Micona sellowiana in different types of vegetation (Grassland, Montane Atlantic forest, Upper Montane Atlantic forest and Araucaria Pine forest). Although such variability could be due to phenotypic plasticity, an alternative explanation for this phenomenon is the existence of genetic differentiation among populations resulting from genetic drift or adaptation to different environments. The goal of the present study was to investigate the extent of genetic structures among populations of Miconia sellowiana using a neutral dominant genetic marker (RAPD - Random Amplification of Polymorphic DNA). There was considerable variability in the studied samples, resulting in 96.5% polymorphic loci and a Gst = 0.13. The analysis of molecular variance showed the... |

| In current assay the serotoninergic system in newly-born Wistar rats underwent pharmacological modification by fluoxetine, a selective serotonin reuptake inhibitor (SSRI), to investigate its repercussion on testicular parameters in adult animals. Thirty animals were distributed according to treatment: control animals (n = 6), animals treated with 1 mg kg-1 (n = 6), 5 mg kg-1 (n = 6), 10 mg kg-1 (n = 6) and 20 mg kg-1 (n = 6) of fluoxetine (IP). When 150 days old, the animals were anesthetized and perfused intra-cardiacally with fixative solution. Testes were routinely processed for inclusion in plastic resin (methacrylate glycol). Further, 4 µm-thick histological sections were stained with toluidine blue/sodium borate 1% and analyzed histometrically.... |

| Among the main problems of some temperate fruit species, such as the apple tree (Malus domestica), are the poor set of fruits and low production. Polyamines and Self-Incompatibility Control Substances (SICS), involving mineral nutrients such as manganese and boron, are the major chemical compounds used to reduce these problems. The aim of this study was to use popular polyamines putrescine (Put) at 0.1, 0.25 mM, spermine (Spm) and spermidine (Spd) both at 0.05, 0.25 mM and SICS at 1, 2 mg L-1, alone or with cotton coverage bags and control to show the effects of these chemical compounds on yield indices and qualitative traits of apple (Malus domestica) cv ‘Red Delicious’. Results showed that Spd (0.25 mM) and SICS (1 mg L-1) had higher effect on yield... |

| The Colorado river delta is a unique coastal system in the world, as it combines two important systems: the Colorado river and the Gulf of California. Consequently, the delta is dominated by bilateral interests, and influenced by administrative, political and natural processes, which involve the countries of the United States and Mexico. Located in the northern part of the Gulf of California, under a condition of natural isolation, a series of environmental attributes have been developed (biotic and abiotic) that are only observed in is region. In this work, the development of the bilateral political relations and the most important ecological characteristics are presented, as well as the management instruments that have been developed for over 80 years.... |

| The effects of different light quality treatments on in vitro growth and multiplication of sugarcane (RB867515) were investigated. The plantlets were cultivated on MS medium containing 1.3 μM 6-benzylaminopurine (BAP), and exposed to five light treatments: three combinations of blue/red LED (70:30, 50:50, 30:70), white-LED and fluorescent lamps, during 24 days. Among the LED light treatments, blue/red combination in 50:50 proportions proved to have the best results for stem length, fresh mass, leaf number and shoot multiplication. Higher content of photosynthetic pigments was also obtained with LEDs. Results suggested that the light quality emitted by LEDs was suitable for plant growth and development and it may be used as... |

| Phytoseiulus macropilis (Banks) (Phytoseiidae) is a natural enemy of Tetranychus urticae Koch (TSSM), a common pest in several cultures, especially in greenhouses. This research aimed to know the biological parameters of a strain of P. macropilis from Vale do Taquari, State of Rio Grande do Sul, feeding on TSSM at different temperatures. The study was initiated with 30 eggs individualized in arenas under the temperature of 20, 25 and 30 ± 1°C and relative humidity of 80 ± 10%. The average length (T) of each generation decreased with the increase of temperature, ranging from 25.71 days at 20°C to 11.14 days at 30°C. The net reproductive rate (Ro) ranged from 45.47 at 20°C to 18.25 at 30°C; the innate capacity for increase (rm) was 0.15 at 20°C, reaching... |

| The aim of this study was to evaluate three stocking densities (20, 40 and 60 larvae L-1), and two daily prey concentrations (400 and 700 Artemia nauplii larvae-1) during the first seven days of active feeding (first phase). In the second phase was evaluate the effect of the different feeding regimes: fasting, dry diet (55% crude protein), Artemia sp. and mixed feeding (Artemia sp. plus dry diet), after 17 days of active feeding on Rhinelepis aspera larviculture. In the first phase, growth was affected only by prey concentration. In the second phase, the dry diet induced higher growth rates than fasting, but lower growth rates than the other treatments. The acceptance of the dry diet was evidenced by an increase in the growth rate from 4.6% day-1 in the... |

| This paper describes the epibiosis of Ostrea cf. puelchana on Callinectes exasperatus (Gerstaecker, 1856), both collected from the estuary of the Paraíba River, in the state of Paraíba, northeastern Brazil. The basibiont crab was captured using a trap installed in mangrove area at a depth of about 2 meters. The oyster was closely attached to the left side of dorsal carapace covering most of the epibranchial, mesobranchial and metabranchial regions. Possible advantages and disadvantages for both the epibiont and the basibiont are discussed. We believe that young O. cf. puelchana may avoid a variety of potential predators due to the considerable movement capacity of C. exasperatus and may also serve as a small protective shield for the basibiont. However,... |

| Senna includes about 300 species with circumtropical distribution, widely represented in the Americas, also occurring in Africa, Australia, Asia and Oceania. The genus is represented in Brazil by 80 species, of which 26 are endemic. The Serra Geral de Licínio de Almeida (SGLA), situated in the central portion of the Cadeia do Espinhaço, state of Bahia, Brazil, presents areas relatively little studied, with great potential for the registration of new information about Brazilian biodiversity. The floristic survey of Senna in the SGLA included analysis of specimens collected from February 2012 to October 2013. The analyses were supplemented with dried collections from the following herbaria: ALCB, BHCB, HUEFS, HUNEB, HRB, MBM and SPF.The genus is represented... |
