1. Esporulação in vitro e inoculação de Exserohilum turcicum em milho
RESUMO A helmintosporiose está entre as principais doenças da cultura do milho. Realizou-se dois ensaios com os objetivos de avaliar a esporulação do fungo diferentes meios de cultura, métodos de inoculação e concentrações de inóculo para Exserohilum turcicum. Para a esporulação em diferentes meios de cultura, testou-se seis diferentes substratos

2. ESTRUCTURAS FUNDAMENTALES CONCRETAS
Abstract Several problems in philosophy of physics have led to ‘ontic structural realism’, i. e., the supposition that, at the fundamental physical level, there are no ‘objects’, but ‘structures’. There are various requirements that a ‘structure’ should satisfy for ‘ontic structural realism’. Structures must be concrete entities, there mu

3. Invading the natural marine substrates: a case study with invertebrates in South Brazil
ABSTRACT The number of biological invasions has grown dramatically in recent decades, as well as the world's human population and coastal development. Anthropogenic habitats, such as pier pilings and break waters, have been constantly added to marine environment, usually concentrated in estuarine areas. These habitats are focal points for marine invasions, b

4. The non-indigenous bryozoan Triphyllozoon (Cheilostomata: Phidoloporidae) in the Atlantic: morphology and dispersion on the Brazilian coast
ABSTRACT Bryozoans constitute an important component of marine-fouling communities of anthropogenic substrata. Many species have been reported as exotic or widespread around the world, typically in ports and harbors of non-polar regions. Here we present the first record of a species of the bryozoan Triphyllozoon in the Atlantic Ocean. Triphyllozoon arcuatum

5. Nesting substrata, colony success and productivity of the wasp Mischocyttarus cassununga
Nesting substrata, colony success and productivity of the wasp Mischocyttarus cassununga. Colonies of the wasp Mischocyttarus cassununga (von Ihering, 1903) are easily found in urban areas. However, in spite of the massive presence of this species in cities, little is known about its nesting habits, colony success and productivity. The present study aimed at

6. Techniques for the detection of pathogenic Cryptococcus species in wood decay substrata and the evaluation of viability in stored samples
In this study, we evaluated several techniques for the detection of the yeast form of Cryptococcus in decaying wood and measured the viability of these fungi in environmental samples stored in the laboratory. Samples were collected from a tree known to be positive for Cryptococcus and were each inoculated on 10 Niger seed agar (NSA) plates. The conventional

7. Reproductive plasticity of Hypostomus affinis (Siluriformes: Loricariidae) as a mechanism to adapt to a reservoir with poor habitat complexity
In this work we describe the gonad morphology and spawning season of Hypostomus affinis (Steindachner, 1877) in a tropical reservoir based on 55 males and 125 females. Our aim was to assess eventual adaptations in reproductive tactics developed by this riverine species inhabiting an oligotrophic reservoir with low habitat complexity, few rocks and few other

8. Potencial hídrico induzido por polietilenoglicol-6000 no vigor de sementes de algodoeiro.
A hidratação é o fator externo mais importante na germinação de sementes. Para simular as condições complexas do solo, soluções com diferentes potenciais hídricos têm sido usadas para umedecer os substratos de germinação. O objetivo deste trabalho foi avaliar os efeitos do estresse hídrico sobre o vigor de sementes de algodão (Gossypium hirsut

9. Influência da composição de substrato do recife na atividade e distribuição de peixes zoobentívoros no arquipélago de Fernando de Noronha, Pernambuco / The influence of substratum composition on the activity and distribution of benthic carnivorous reef fishes of the Fernando de Noronha Archipelago
Reefs provide shelter and food for several fish species and, thus, there may be a correlation between the abundance and behaviour of fishes and the reef bottom composition-Physical factors, such as water movement and depth, may also have a profound impact in species distribuiton and activity on reefs. Here, the possible relationship between the distribution

10. Obtenção de células de Salmonella resistentes a desidratação para o preparo de material de referência / Attainment of resistant cells of Salmonella the dehydration for the preparation of material of reference
Programs of control and management of the quality in laboratories, the necessity of standardization of the analysis methods and repeatability of the experimental data have stimulated the increase of the use of Reference Material (RM) in the microbiological analyses. Considering that the stages of preparation and storage of the MR are stress processes that ca

A família Chironomidae constitui um dos principais grupos de insetos aquáticos, estando presente em uma grande variedade de ambientes e participando de vários processos ecológicos, como a ciclagem de nutrientes e transferência energética. No Sul do país, poucos estudos são direcionados a esta comunidade, não existindo trabalhos na região de Santa M
