1. Caracterização da infecção por tripanossomatídeos (Protozoa: Kinetoplastida) presentes em três espécies de cascudo (Pisces: Loricariidae) do Rio Mogi-Guaçu, SP / Characterization of infection by Tripanossomatídeos (Protozoa: Kinetoplastida) present three species of armored catfish (Pisces: Loricariidae) from Mogi-Guaçu river, SP
Trypanosomes have been reported in several species of fish that inhabit salt and fresh waters. The majority of these protozoan species are described based on morphologic features. The parasites are heteroxenic and are transmitted by leeches. This work aims to characterize the prevalence and density of infection by Trypanosoma sp. present in the blood of thre

2. CARACTERIZAÇÃO DE ACESSOS POLIMÓRFICOS DE ARROZ VERMELHO DO RIO GRANDE DO SUL POR DESCRITORES MORFOLÓGICOS E MICROSSATÉLITES / CHARACTERIZATION OF RED RICE POLYMORPHIC ACCESSES IN THE STATE OF RIO GRANDE DO SUL BRAZIL BY MORPHOLOGIC DESCRIPTORS AND MICROSATELITTE MARKER
This work has for objective to evaluate the phenothypic and genothypic characteristics of different morphologic types of red rice that happen in areas of production of irrigated rice of the State of Rio Grande do Sul - Brazil, for morphologic descriptors and molecular markers, and his response to the use of chemical technology. For this reason, it were condu

3. Inferências carioevolutivas sobre grupos crípticos de peixes marinhos e estuarinos
Cytogenetic studies have been revealing a great diversity not detected, until then, in several families of fishes. Many of these groups, especially those that exhibit great diversity, like Perciformes and Siluriformes, possess species with difficult morphologic characterization, called cryptic species, commonly detected through karyotypic analyses, which rev

4. CaracterizaÃÃo molecular de cultivares de batata Solanum tuberosum L. utilizando marcadores RAPD e SSR / Molecular characterization of potato cultivars (solanum tuberosum L.) using RAPD and SSR markers.
The introduction of new cultivars of potato (Solanum tuberosum L.) has been an adopted strategy to increase the productivity of this culture. Potato presents narrow genetic base, what makes the identification of their cultivars using morphologic markers difficult. Thus, it is necessary to use methods that can identify them and evaluate their genetic variabil

5. Seleção e caracterização de estirpes de Bacillus thuringiensis tóxicas à spodoptera eridania (Cramer), Spodoptera cosmioides (Walker) e Spodoptera frugiperda (smith) (Lepidoptera: noctuidae)
Among the pests of cultivated plants the species of the gender Spodoptera is one of the most important. Spodoptera cosmioides and Spodoptera eridania were reported as cotton (Gossypium hirsutum) and soybean pests (Glycine max), while Spodoptera frugiperda corn (Zea mays) and cotton pests. The objectives of this research were select strains of Bacillus thurin

6. Soils and environments of the Ferriferous Quadrangle (MG) and forestry suitability of the Coastal Plains / Solos e ambientes do QuadrilÃtero FerrÃfero (MG) e aptidÃo silvicultural dos Tabuleiros Costeiros
Two quite different Brazilian environments were approached in this work: the Ferriferous Quadrangle, located in the center-south portion of the State of Minas Gerais, and Coastal Plains, which extend in narrow strip along the coast from the State of Rio de Janeiro to AmapÃ. The first was studied in a more general context, with respect to the distribution of

7. Caracterização morfo-fisiológica e identificação de fragmentos de cDNA diferencialmente expressos de tegumentos de sementes de soja com permeabilidade contrastante / Morpho-physiologic characterization and identification of fragments of cDNA distinguishing expressed in soybean seed coat with contrasting permeability
Some works have reported the existence of contrasting soybean genotypes for physiological quality of seeds. There are such differences because of the presence of seeds with total or partial impermeability for water absorption into the coat that make them less susceptible to mechanical damages, weather adversities, deterioration by humidity and pathogen occur

8. Caracterização morfológica e molecular de híbridos do cruzamento entre Triatoma maculata (Erichson, 1848) e Triatoma pseudomaculata Corrêa &Espínola, 1964 (Hemiptera: Reduviidae). / Morphologic and molecular characterization of hybrids from the cross breeding among Triatoma maculata (Erichson, 1848) and Triatoma pseudomaculata Corrêa &Espínola, 1964 (Hemiptera: Reduviidae)
Due to its great morphological similarities, Triatoma maculata and Triatoma pseudomaculata, classified by Carcavallo et al. (2002) in the maculata complex, were considered the same species until 1964 (Corrêa e Espínola, 1964). These species are alopatric and, according to Schofield (1988), T. maculata would be introduced in the brazilian Northeastern by mi

9. Análise da variabilidade genética e Avaliação da fixação biológica de nitrogênio entre acessos de amendoim (Arachis hypogaea L.) / Analisys of genetic variability and assessment of biological nitrogen fixation among peanut (Arachis hypogaea L.) accessions
The peanut is a crop worldwide cultivated and it presents a high potential to biological nitrogen fixation (BNF). However peanut is considered a very promiscuous crop, what makes necessary a hard work of selection of rhizobial efficient and competitive strains to produce inoculants for this crop. The selection of an efficient association depends of the knowl

10. Caracterização morfológica e molecular de acessos de feijão-fava (Phaseolus lunatus L.,Fabaceae) da Coleção de Germoplasma do Departamento de Agronomia da UFRPE.
Twenty-two lima-beans accessions, which compound the Germoplasm Collection of the Agronomy Department of Federal Rural University of Pernambuco (UFRPE), coming from the States of Ceará, Paraíba and Pernambuco, Brazil, were characterized by their morphological and molecular characteristics (RAPD Random Amplified Polimorphiysm of DNA). In morphological analy

11. Selection and caracterization of Metarhizium anisopliae for the control of Mahanarva fimbriolata (Hemiptera: Cercopidae) in sugar-cane. / Seleção e caracterização de Metarhizium anisopliae visando ao controle de Mahanarva fimbriolata (Hemiptera: Cercopidae) em cana-de-açúcar.
This research was carried out to evaluate the pathogenicity of isolates of the entomopatogenic fungus Metarhizium anisopliae against the spittlebug, Mahanarva fimbriolata, and to characterize them morphologically and genetically through RAPD method. The selection was made under laboratory condition, using nymphs collected at field. The fungus was sprayed on

12. Morphologic and molecular characterization in rice mutant (Oryza sativa L.) to aluminium toxicity tolerance / Caracterização morfológica e molecular em mutantes de arroz (Oryza sativa L.) quanto à tolerância a toxidez por alumínio
Fatores químicos do solo limitam o crescimento da raiz em solos ácidos, diminuindo a produção do cultivo. A toxidez por alumínio é considerada um dos mais importantes problemas de toxicidade de metais em solos ácidos com pH≤5 por representar um fator limitante do crescimento para as plantas. O presente trabalho teve como objetivo caracterizar mo
