13. Natural history of Micrablepharus maximiliani (Squamata: Gymnophthalmidae) in a Cerrado region of northeastern Brazil
Micrablepharus maximiliani (Reinhardt & Luetken, 1861) is a microteiid lizard widely distributed in the open areas of South America. Little is known about its ecology and reproductive biology. Here, we analyzed aspects of the natural history of a population of M. maximiliani from a Cerrado area in the state of Piauí, northeastern Brazil. Our results suggest

14. Use of artificial substrates of different colors for oviposition by the brown stink bug Euschistus heros (Hemiptera, Pentatomidae)
Aiming to contribute to a rearing methodology for the brown stink bug, Euschistus heros, in the laboratory, we evaluated oviposition on artificial substrates of different colors. During six days, oviposition was evaluated daily, by counting the total number of eggs, number of clutches, and eggs/clutch. Females laid 12,463 eggs, in 1,677 clutches, resulting i

15. Excreção de nitrogênio em embriões de iguana Iguana iguana (Reptilia; Squamata) / Nitrogen excretion in the green iguana (Iguana iguana) embryos (Reptilia; Squamata)
A Table of embryonic stages can be used to detect similarities and differences in developmental features between groups and as a tool for studies based on embryonic phase. In this study, eggs of the lizard Iguana iguana were used to elaborate a staging table and to determine the nitrogen excretion pattern during the development. Iguana is a convenient model

16. Análise qualitativa e quantitativa de compostos de borracha destinados à fabricação de revestimentos de embreagem / Qualitative and quantitative analysis of rubber compounds destined for clutch facings manufacture
In this work it was developed a methodology for qualifying and quantifying rubber compounds destined for facings manufacture. These compounds are formed by a large number of components which use, beyond the elastomeric base, a resin that is used as a process agent, vulcanization agents and different fillers, each one with a specific function. The elastomeric

17. Reproductive ecology and diet of Cnemidophorus ocellifer Spix 1825 (Squamata: Teiidae) in a coastal area from northeastern Brazil / Ecologia reprodutiva e dieta de Cnemidophorus ocellifer Spix 1825 (Squamata: Teiidae) em Ãrea de tabuleiro no nordeste do Brasil
Chapter 1:Reproduction of Cnemidophorus ocellifer was studied based on data collected from September 2009 to August 2010 in a coastal area of the SÃo GonÃalo do Amarante municipality, CearÃ, Brazil. Lizards were captured by manual collection, with the aid of pressure rifle or tourniquet and, after dead, individuals were dissected for sex determination by

18. Immature stages and natural history of the Andean butterfly Altinote ozomene (Nymphalidae: Heliconiinae: Acraeini)
The immature stages (eggs, larvae and pupae), oviposition and larval behavior of Altinote ozomene (Godart, 1819) are described here for the first time. Larvae were reared from egg clutches collected from the host plants Erato vulcanica (Klatt) H.Rob and Munnozia senecionidis Benth (Asteraceae). Eggs were laid in groups on the undersides of leaves. The number

19. Sedimentary characteristics and their effects on hatching success and incubation duration of Caretta caretta (Testudines: Cheloniidae) in Espirito Santo, Brazil
The beaches of Espírito Santo encompass the most important nesting sites of the loggerhead sea turtle, Caretta caretta (Linnaeus, 1758), in the South Atlantic Ocean. Previous research has shown that, unlike other nesting sites in Brazil, Espírito Santo harbors a large percentage of male individuals, which play an important role in maintaining the equilibri

20. Breeding biology and reproductive success of Polystictus superciliaris (Aves: Tyrannidae), an uncommon tyrant-flycatcher endemic to the highlands of eastern Brazil
Polystictus superciliaris (Wied, 1831) is a small tyrant-flycatcher endemic to mountaintops in the highlands of eastern Brazil. In this paper we present the first description of the breeding biology of P. superciliaris and estimate its reproductive success from a population inhabiting rocky outcrops. This study was conducted during 2005 in the Parque Estadua

21. The influence of clutch and brood sizes on nesting success of the biscutate swift, Streptoprocne biscutata (Aves: Apodidae)
The nesting success of three colonies of Streptoprocne biscutata (Sclater, 1866), and the influence of clutch and brood size on nesting success of species were studied. Overall, apparent nesting success was 58% and Mayfield nesting success was 53%. Nest survival during incubation (64%) was lower than during the nestling period (83%). During incubation, clutc

22. Influência da densidade de ovos de Diaphania hyalinata (L.) (Lepidoptera: Crambidae) na capacidade de parasitismo de Trichogramma exiguum Pinto & Platner e Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae)
The effects of the egg density of Diaphania hyalinata (L.) on several biological parameters of Trichogramma exiguum Pinto & Platner and T. pretiosum Riley were investigated. For that, 24h-old egg masses were isolated in glass tubes (15 replicates; 1 egg mass = 1 replicate), and offered to parasitization by a newly-emerged female of T. pretiosum or T. exiguum

23. Estudo comparativo de trens de potência com disco de embreagem convencional e com volante de dupla massa de motores flex e diesel / Comparative study of the powertrain with conventional clutch disc and dual mass flywheel for engines flex and diesel
O motor de combustão interna, embreagem, transmissão, diferencial, eixo Cardan, semieixos e rodas motrizes compõem o trem de potência de um veículo que, por diversas razões de refinamento e peso, oferecem baixa "resistência" aos ruídos decorrentes da irregularidade de rotação do motor. O presente trabalho reúne elementos para analisar os efeitos d

24. Reproductive biology of the mullet Mugil liza (Teleostei: Mugilidae) in a tropical Brazilian bay
The reproductive biology of Mugil liza Valenciennes, 1836 is described as a contribution to an elaborate management programm. A total of 243 specimens (89 males and 154 females) were collected in the Sepetiba Bay in south-eastern Brazil from July/2006 to June/2007. The gonadosomatic index (I G) and the sequential development of the ovaries observed through h
