Variabilidade genética em populações de Jabiru mycteria (Lichtenstein, 1819) e Mycteria americana (Linneaus, 1758) (Aves, Ciconiidae): fluxo gênico e filogeografia
(Universidade Federal de São Carlos, 2006-06-07)
This study evaluates the levels of variability, genetic structure, and phylogeographical
patterns of wild populations of Jabiru Storks (Jabiru mycteria) and Wood Storks (Mycteria
americana). These species belong to the ...
Estudo de haplótipos do DNA mitocondrial de colhereiros (Aves, Ordem Ciconiiformes, Platalea ajaja)
(Universidade Federal de São Carlos, 2005-12-02)
Roseate spoonbill (Platalea ajaja) is a neotropical bird with wide geographic distribution in intercontinental and coastal wetland habitats. Populations are morphologically indistinguishable, with no apparent differentiation ...
Relações genéticas entre plantéis de reprodutores do camarão marinho Litopenaeus vannamei, através do seqüenciamento dos genes RNAr 16S e COI do DNAmt
(Universidade Federal de São Carlos, 2003-08-22)
The evaluation of genetic relationships among broodstocks is a useful tool for culture management programs. In the present work, the relationships amongst four broodstocks of the marine shrimp Litopenaeus vannamei were ...
Estrutura genética das populações de abelhas africanizadas (Apis mellifera L.) do Brasil determinada por meio de polimorfismos do DNA mitocondrial.
(Universidade Federal de São Carlos, 2004-08-25)
The Apis mellifera subspecies are classified into evolutionary branches originally distributed in the African (branches A and Y), European (branches C and M) and Asian (branch O) continents. This distribution has been ...
Aspectos da biologia, variabilidade genética e estrutura sociogenética dos agregados de Digelasinus diversipes (Kirby, 1882) (Hymenoptera: Agridae).
(Universidade Federal de São Carlos, 2003-07-29)
Symphyta is a suborder of Hymenoptera, which presents primitive characters, like absence of constriction at the base of the abdomen. Symphyta larvae are phytophagous and feed gregariously, causing damage to agricultural ...
Estrutura genética das populações de abelhas africanizadas (Apis mellifera L.) da Colômbia estimada através de marcadores nucleares e mitocondriais.
(Universidade Federal de São Carlos, 2004-07-30)
In 1957 a hybridization process occurred in South America between European and African bees just introduced in the continent. Since the arrival of the Africanized bees to Colombia in 1978 and their total establishment four ...
Estudo da infestação de fêmeas bovinas de corte pelo Rhipichepalus (Boophilus) microplus, Haematobia irritans e Dermatobia hominis
(Universidade Federal de São Carlos, 2006-10-31)
In tropical regions, resistance of cattle to external parasites is an
important factor determining efficiency of the production systems. The objectives in
this study were to evaluate the degree of resistance of Nelore ...
