Problemas taxonômicos da família Threskiornithidae: filogenia molecular e o caso de Eudocimus
(Universidade Federal de São Carlos, 2011-03-01)
The family Threskiornithidae includes 13 genera and 32 species, but the relationships among genera, species or subspecies have been little studied. This family is traditionally divided into two subfamilies: Plataleinae and ...
Caracterização citogenética de populações alopátricas do gênero Hoplias (Characiformes, Erythrinidae), com enfoque nos grupos malabaricus e lacerdae
(Universidade Federal de São Carlos, 2010-02-01)
Erythrinidae represents a relatively small family of Neotropical fish, presenting a great geographical distribution. It is composed only by three genera, Hoplias, Hoplerythrinus and Erythrinus. The genus Hoplias is most ...
Marcadores cromossômicos em Hoplias malabaricus (Characiformes, Erythrinidae). Citogenética comparativa entre cariomorfos
(Universidade Federal de São Carlos, 2010-02-08)
Hoplias malabaricus, a widespread Erythrinidae fish, is characterized by a karyotypic diversity, with seven karyomorphs already described. This report presented a comparative study of the karyomorphs A, B, C and D, which ...
Filogenia molecular e filogeografia do gênero Salminus (Characiformes)
(Universidade Federal de São Carlos, 2016-09-30)
Salminus is a genus comprised of four Neotropical medium- and large-sized fishes species,
top predators, with both recreational and commercial importance. The paucity of information
on taxonomy, phylogeny and phylogeography ...
Estudos citogenéticos em espécies da família Paradontidae (Actinopterygii: Characiformes), com enfoque no papel dos DNAs repetitivos na evolução cariotípica do grupo
(Universidade Federal de São Carlos, 2016-07-01)
Parodontidae is organized in three genera according to their morphological
characteristics: Parodon, Saccodon and Apareiodon. The diploid number is conserved
in this group with 2n=54 chromosomes, with species without ...
Citogenética comparativa em espécies de Hypostomus (Siluriformes, Loricariidae, Hypostominae). Contribuição da fração repetitiva do genoma para a diversidade cromossômica do grupo
(Universidade Federal de São Carlos, 2012-11-14)
Hypostomus is the widest genus of the armored catfishes in South America. This group presents a great diversity in color pattern and morphology, and shows not conservative chromosomal features. Different classes of repetitive ...
Estudos evolutivos em Auchenipteridae (Siluriformes): citogenética, DNA mitocondrial e DNA satélite
(Universidade Federal de São Carlos, 2013-02-04)
The neotropical freshwater fish fauna is the most diverse in the world, with more than 4.000 descrbed spcecies. In Brazil, about 2.500 species of freshwater fishes are considered valid, and the most formallyand a small ...
Evolução molecular da família gênica dos receptores de odores e proteínas ligantes a feromônios e genética de populações de genes quimiossensoriais em espécies de Anastrepha do grupo fraterculus
(Universidade Federal de São Carlos, 2016-05-02)
This dissertation is divided into three chapters. In the first chapter, we provide a concise
literature review that discusses key theoretical concepts, the rationale, and main objectives
outlined for this study. The ...
Evolução molecular e padrões de expressão de genes da família das proteínas ligantes a odores (OBPs) em duas espécies de moscas-das-frutas do grupo Anastrepha fraterculus
(Universidade Federal de São Carlos, 2016-04-18)
Odorant-binding proteins (OBPs) are of great importance for survival and reproduction
since they participate in initial steps of the olfactory signal transduction cascade,
solubilizing and transporting chemical signals ...
Expressão heteróloga em Saccharomyces cerevisiae e ensaio de atividade de uma ß-1,4- endoglucanase isolada do cupim Velocitermes heteropterus (Isoptera, Termitidae)
(Universidade Federal de São Carlos, 2013-10-01)
The current world scenery points out that the environment changes in the Earth planet is due to the intense use of fossil fuels along decades. This panorama launched the needs for the replacement of fossil fuels to sustained ...
