1. Selecting alternative sterile and non-sterile substrates for mycorrhizal inoculant production
ABSTRACT Alternative substrates were evaluated for mycorrhizal inoculants production considering the beneficial effects of arbuscular mycorrhizal fungi (AMF) for plants and environment. The first step of the experiment aimed at evaluating the potential of substrates produced from sugarcane bagasse (SB), coconut fibre (CF) and urban waste compost (UWC) to pro

3. DORMANCY BREAKING, GERMINATION, AND PRODUCTION OF MIMOSA BIMUCRONATA (DC.) KUNTZE SEEDLINGS
ABSTRACT Mimosa bimucronata is a pioneer, easily adapted, fast-growing species used in restoration programs. The objectives of this study were to experimentally compare (1) methods for dormancy breaking; (2) suitable temperature and substrate for germination; and (3) suitable light intensity and substrate volume for seedling production of M. bimucronata. In

4. Organization of fish assemblages in blackwater Atlantic Forest streams
RESUMO O objetivo do estudo foi testar se espécies de peixes ocupam diferentes mesohabitats definidos por critérios específicos de tipos de substrato em riachos de águas pretas de Mata Atlântica. Durante a estação de baixa vazão (junho-setembro/2016), foram amostrados quatorze riachos costeiros de águas pretas no litoral de São Paulo, Brasil. Para

5. Height and number of shoots on the survival and development of micropropagated bamboo plantlets during pre-acclimatization
RESUMO Durante a multiplicação in vitro de bambu, é rotineiro ocorrer a formação de agregados de brotos. Uma vez individualizados, eles podem render maior número de mudas do que se plantados agrupados. Objetivou-se avaliar o efeito da relação entre a altura e o número de brotos iniciais em mudas de bambu micropropagadas na sobrevivência e desenvolv

6. Soil-vegetation relationships and community structure in a "terra-firme"-white-sand vegetation gradient in Viruá National Park, northern Amazon, Brazil
ABSTRACT Viruá National Park encompasses a vast and complex system of hydromorphic sandy soils covered largely by the white sand vegetation ("Campinarana") ecosystem. The purpose of this study was to investigate a vegetation gradient of "terra-firme"-white sand vegetation at the Viruá National Park. Nine plots representing three physiognomic units were ins

7. Antiseptics and microcosm biofilm formation on titanium surfaces
Abstract Oral rehabilitation with osseointegrated implants is a way to restore esthetics and masticatory function in edentulous patients, but bacterial colonization around the implants may lead to mucositis or peri-implantitis and consequent implant loss. Peri-implantitis is the main complication of oral rehabilitation with dental implants and, therefore, it

8. Characterization and Distribution of Pyrogenic Carbon in a Fraction of Archaeological Black Earth from Caxiuanã
This study aims to determine the atomic ratio of O/C in an archaeological black earth (ABE) profile of the Ilha de Terra site, a region of Caxiuanã in the Pará State, Brazil, to determine the types of pyrogenic carbon (PyC) particles and to infer the source of biomass and burning temperature necessary to produce the PyC. The O/C ratios were monitored us

9. Optimization of the production of mycorrhizal inoculum on substrate with organic fertilizer
The system for production of inoculum of arbuscular mycorrhizal fungi (AMF) using sand and vermiculite irrigated with nutrient solution is promising. However, organic amendments added to the substrate can stimulate sporulation of AMF and replace the nutrient solution. The aim of this study was to maximize the production of AMF (Acaulospora longula, Claroideo

10. Manejo da fertirrigação em Physalis cultivado em vaso com areia
With the increased media coverage of the nutraceutical properties of small fruits like strawberries, raspberries and other, consumer interest increases, and consequently its production. A species of the nightshade family that see recently is being cultivated Physalis L.. Its cultivation is simple, and managed according to the tomato crop. Several authors hav

11. Controles da produção primária em um Córrego de Mata Atlântica / Controls of primary production in an Atlantic Rainforest Stream
This dissertation consists of two chapters, each corresponding to an independent study. In an Atlantic Rainforest stream, Rio de Janeiro, Brazil, the effects of herbivores and of environmental controls on periphyton were studied. In the first experiment I tested the effects of the shrimp Potimirim glabra, an ecosystem engineer, on the metabolic parameters of

12. Resposta do arroz de terras altas a diferentes doses de carvão vegetal: desenvolvimento da planta e deficiência hídrica / Resposta do arroz de terras altas a diferentes doses de carvão vegetal: desenvolvimento da planta e deficiência hídrica / Response of upland rice to different doses of charcoal, plant development and water deficit / Response of upland rice to different doses of charcoal, plant development and water deficit
The average national rice yield was 11,3 million tones, with a harvested area of about 2,7 million hectares (IBGE 2010). Part of this comes from upland production systems in savannas that have high acidity, low fertility, with low phosphorus and potassium levels, low cation exchange capacity and high aluminum saturation. Upland rice in the Brazilian savannas
