25. Caracterização morfológica de ovinos no Brasil, Uruguai e Colômbia
Morphometric data was collected on sheep from naturalized breeds in Brazil, Uruguay and Colombia, as wella s from some commercial breeds, for comparison. Phenotypic characterization was carrie dout using size, colour and conformation of the animals, as well as sixtyeen morphometric traits. data was analysed using PROC GLM, CORR and PRINCOMP of SAS .

27. Morphometric and molecular characterization of Anastrepha bistrigata Bezzi and Anastrepha striata Schiner (Diptera: Tephritidae) / Caracterização morfométrica e molecular de Anastrepha bistrigata Bezzi e Anastrepha striata Schiner (Diptera: Tephritidae)
Because of the fact that Anastrepha striata Schiner and Anastrepha bistrigata Bezzi are very similar morphologically and may also occur sympatrically, this study aimed to propose different ways to characterize them by using wing and aculeus morphometry, and mitochondrial DNA sequencing. This work also aimed to develop species-specific primers to allow for th

28. Sistemática morfológica e molecular de ácaros fitófagos do gênero Brevipalpus Donnadieu de importância econômica e quarentária para o Brasil / Morphological and molecular systematics of phytophagous mites of brevipalpus donnadieu genus of economic and quarantine importance to Brazil
Brevipalpus Donnadieu is the most importante genus in the Tenuipalpidae family. This genus presents about 300 species distributed around the world. Brevipalpus mites present agricultural importance because they are pests of several crops and especially due to their role as vectors of serious plant viroses. In Brazil, the main Brevipalpus species are B. phoen

29. Utilização de técnicas citogenéticas, de citometria de fluxo e de imagem para caracterização do genoma de Coffea canephora e C. arabica / Utilization of cytogenetic, flow and image cytometric techniques for genome characterization of Coffea canephora and C. arabica
The application of cytogenetic, flow and image cytometric techniques has been enabling the genome characterization of Coffea arabica L. and Coffea canephora Pierre ex Froehner. These approaches have been providing relevant information for evolutionary studies and breeding programs. Considering the need of increasing the information available on the genomes o

30. Characterization of Tyzzeria parvula (Kotlan, 1933) Klimes, 1963 oocysts (Apicomplexa: Eimeriidae) of the greylag goose (Anser anser Linnaeus, 1758) in Brazil. / Caracterização dos oocistos de Tyzzeria parvula (Kótlan, 1933) Klimes, 1963 (Apicomplexa: Eimeriidae) do ganso doméstico (Anser anser) no Brasil.
The principal objective of this research was to describe an coccidium found in the feces of greylag goose Anser anser Linnaeus, 1758. Based on morphometric analysis of these sporulated oocysts, they were classified as Tyzzeria parvula (Kótlan, 1933) Klimes, 1963. This coccidium was described for the firt time in goose of Brazil at rural and urban areas from

31. Estratégias de análise da diversidade em germoplasma de cajueiro (Anacardium spp. L.) / Strategies for evaluating the diversity in germplasm of the cashew (Anacardium spp. L.)
The cashew (Anacardium occidentale) is a perennial arboreal fruit tree that is actually cropped in several tropical countries around the World. The Brazilian territory is probably the original and main diversity center of this tree fruit, as well as for most species of the genus Anacardium. On the other hand, studies concerning to the evaluation and characte

32. Effect of the sexed semen process through flow cytometry and cryopreservation on the morphometry of spermatozoid heads and chromatin stability / Efeito do processo de sexagem de sêmen por citometria de fluxo e crioprervação sobre a morfometria da cabeça de espermatozóides e estabilidade de cromatina
Bovine sexed semen has been commercially evaluated due to its great economic value for sex selection in milk and beef cattle raising, with purity around 90% for the desired sex. However, its employment depends on the cryopreservation use. The objective of the present study was to analyze the spermatic chromatin stability and morphometric alterations in sperm

33. Caracterização fisica de ambientes carsticos atraves de sensoriamento remoto e SIG : o caso do Parque Nacional Cavernas do Peruaçu - Januaria/ Itacarambi, MG / Characterization of karstic environments by means of remote sensing and GIS : the case of Cavernas do Peruaçu National Park, Januaria/ Itacarambi, Minas Gerais State, Brazil
This dissertation deals with the characterization of karstic environments through the use of remote sensing and GIS techniques, using as a case study the Cavernas do Peruaçu National Park, located in Januária and Itacarambi counties, Minas Gerais State, Brazil. The selection of this area was due to its relevance in terms of the speleological, archeological

34. Síndrome de emagrecimento progressivo dos calitriquídeos - processo de má absorção semelhante à doença celíaca humana - caracterização clínica, laboratorial e anatomopatológica / Wasting marmoset syndrome is a malabsorption process similar to celiac disease: clinical and pathology characterization
Wasting marmoset syndrome (WMS) is an important cause of morbidity and mortality of marmosets and tamarins kept in captivity. The etiology of this syndrome has not been established and its main features are progressive weight loss, diarrhea, colitis, anemia, hind limb paralysis, and alopecia. The aims of this research were to demonstrate that WMS is a malabs

35. Morphologic and morphometric analysis of Hepatozoon spp. (Apicomplexa, Hepatozoidae) of snakes
Hepatozoon species are the most abundant hemoparasites of snakes. Its identification has been based mainly on the morphologic characterization of the gamonts in the peripheral blood of the vertebrate host and also of the cysts found in the internal organs of the vertebrate and invertebrate hosts. Using a computerized image analysis system, we studied five sp

36. Desenvolvimento inicial de larvas de Rhaphiodon vulpinus Agassiz (Characiformes, Cynodontidae)
The cynodontid fish Rhaphiodon vulpinus Agassiz, 1829, known as "peixe-cachorro", is the only species of the family oceurring in the Pantanal of Mato Grosso. The initial development of its larvae was characterized, based on material collected with a 500 µm mesh size plankton-net, in several biotopes of the Pantanal of Barão de Melgaço, State of Mato Gross
