1. Molecular sexing and intersexual differences in the morphometry of the Hangnest Tody-Tyrant Hemitriccus nidipendulus (Passeriformes: Rhynchocyclidae)
ABSTRACT Variation in the morphometry of individuals in a population may result from natural or sexual selection. In the present study we investigated morphometric differences between males and females of a bird species endemic to the Brazilian Atlantic Forest, the Hangnest Tody-Tyrant, Hemitriccus nidipendulus (Wied, 1831), with no apparent sexual dimorphis

2. Development of an Extraction Protocol for Fetal Sexing from the Fourth Week of Gestation by Real Time PCR
Abstract Low number of fetal cells in maternal blood limited the use of fetal materials in diagnostic and clinical applications. This research developed a technology which allowed the extraction of fetal DNA by a non-invasive method that offers no risk to the mother or fetus. A total of 132 pregnant women participated in this inquiry. The DNA extraction was

3. Somatic embryogenesis in the commercial papaya hybrid UENF/Caliman 01 relying on plantlet production from sexed adult hermaphrodite donor plants
Abstract: Somatic embryogenesis from explants from hermaphrodite papaya mother plants is an alternative for the production of true-to-type plants without the need for sexing. This study aimed to analyze hormonal and osmotic inducers in different somatic embryogenesis stages in the commercial hermaphrodite hybrid papaya UENF/Caliman 01. Leaf disks from in vit

4. Bioimpedance as a Non-Invasive Method to Evaluate Eggs and Poultry
ABSTRACT The need to comply with animal welfare has motivated the research for non-invasive methods that allow the evaluation of poultry and eggs to be painless while providing accurate measurements. In this scenario, bioelectrical impedance was tested as a minimally invasive tool for sexing day-old chicks of two different chicken strains and for evaluating

5. A morphometric method of sexing white layer eggs
The present study was carried out to determine the sex of the fertilized white layer eggs with using morphological measurements. A total of 300 Super Nick White Layer (54 wks of age) eggs were incubated and sexed in the end of incubation period. Before incubation egg length, width and weight were measured. The egg volume and shape index were estimated with u

6. Non-invasive genetic sampling for molecular sexing and microsatellite genotyping of hyacinth macaw (Anodorhynchus hyacinthinus)
Molted feather sampling is a useful tool for genetic analyses of endangered species, but it is often very laborious due to the low quality and quantity of the DNA obtained. In the present study we show the parts of feathers that resulted in better yield of DNA. In descending order these were: blood clot outside the umbilicus, umbilicus (without blood clot),

7. InovaÃÃes tecnolÃgicas na sexagem, manejo reprodutivo e crescimento do pirarucu, Arapaima gigas (SCHINZ, 1822), (Actinopterygii, Arapaimidae) cultivado no Centro de Pesquisas em Aquicultura Rodolpho von Ihering (CPA) do DNOCS, Pentecoste, Estado do Cearà / Technological innovations in sexing, management and reproductive growth of pirarucu, Arapaima gigas (Schinz, 1822) (Actinopterygii, Arapaimidae) grown in the Center of Research in Aquaculture Rodolpho von Ihering (CPA) of DNOCS, Pentecoste, State of Ceara
A tese trata da sexagem, reproduÃÃo, alevinagem e crescimento do pirarucu, Arapaima gigas. No primeiro capÃtulo foram revelados aspectos histÃricos da introduÃÃo e reintroduÃÃo do pirarucu nos aÃudes do nordeste do Brasil objetivando o desenvolvimento de pesquisas de manejo, crescimento e reproduÃÃo voltadas à produÃÃo aquÃcola. No segundo cap

8. Massa corporal e morfometria de Conopophaga melanops (Aves: Conopophagidae): uma comparação intrasexual e entre áreas continental e insular de Mata Atlântica, na região da Baía da Ilha Grande, RJ / Body mass and morphometry of Conopophaga melanops (Aves: Conopophagidae): an intrassexual comparison between mainland and island areas of Atlantic forest in the region of the Bay of Ilha Grande, RJ.
A forma e o tamanho de um determinado organismo devem caracterizar aspectos ecológicos, uma vez que a morfometria é resultado da evolução. Diferenças nos caracteres morfológicos podem ter sido causadas por isolamento geográfico, mesmo em períodos de tempo relativamente curtos. O estudo da morfologia ecológica é uma tentativa de compreender a relaç

9. Determinação da porcentagem de espermatozóides portadores de cromossomos X e Y no sêmen sexado mediante PCR em tempo real / Determination of the proportion of X- and Y- bearing spermatozoa in bovine sexed semen by real time PCR
There are different biotechnologies to apply to increase the animal production nowadays, reproduction techniques are including. The artificial insemination (AI), for example, is a technique very used during many years ago and it is used at extensive production. The aim of this technique is to increase the numbers of pregnancies with just one ejaculation what

11. Estabelecimento de metodologias de análise do DNA livre plasmático para o diagnóstico Pré-natal não invasivo: sexagem fetal
Neste trabalho propusemos e analisamos metodologias empregadas no uso da tecnologia dos Ácidos Nucléicos Livres de Células Fetais (cffDNA = Cell Free Fetal DNA) no diagnóstico pré-natal não invasivo (DPIN = Non-invasive Prenatal Diagnosis). Dada a modernidade das tecnologias empregadas e a sua repercussão nas famílias envolvidas, procuramos discutir

12. Culicídeos associados a bovinos de leite, no sul do Rio Grande do Sul, Brasil
The occurrence of mosquitoes in the authoring environment of dairy cattle was verified in southern Rio Grande do Sul. For collection of specimens, it was installed a Magoon trap, in which during a couple of cattle-approximately six months of age was placed. Samples were collected during 24 hours, twice a month for 12 months. After 24 hours, the cattle were r
