Demografia e diversidade genética de onça-parda (Puma concolor) e jaguatirica (Leopardus pardalis) da Estação Ecológica de Caetetus SP e sua importância para a conservação desses felinos
(Universidade Federal de São Carlos, 2013-02-28)
The loss and fragmentation of habitat due to intensive human intervention are the main threats to natural populations. Species with low density and large home range, like felids, are the most threatened species by these ...
Alterações bioquímico-fisiológicas em pacu (Piaractus mesopotamicus Holmberg 1887) exposto a um inseticida à base de deltametrina
(Universidade Federal de São Carlos, 2013-02-21)
The use of insecticides is increasing not only for agriculture purposes but also against threats to public health caused by insects. However, in the last few years it is possible to see a frequent replacement of current ...
Avaliação dos efeitos de polimorfismos e da origem parental do alelo na expressão de genes candidatos à característica maciez da carne em bovinos da raça Nelore
(Universidade Federal de São Carlos, 2012-02-29)
Tenderness is the main trait appreciated by consumers of bovine meat, however Nellore animals that comprise the largest part of Brazilian cattle, have lower tenderness when compared with European animals. In this way, it ...

(Universidade Federal de São Carlos, 2012-05-17)
Pilosocereus machrisii is a columnar cacti with natural fragmented distribution; restrict to campos rupestres vegetation patches or rocky outcrops on the Cerrado domain; in Central and eastern Brazil. These features makes ...
Construção e caracterização de uma enzima quimérica obtida pela fusão gênica endoglucanase-xilanase de Trichoderma harzianum
(Universidade Federal de São Carlos, 2013-02-05)
The sugarcane bagasse is a lignocellulosic material that can be converted into ethanol by action of cellulases and xylanases. These enzymes act synergistically to convert cellulose and hemicellulose into glucose. In order ...
Associação entre polimorfismos no gene da glicoproteína-P (PgP) e resistência múltipla a anti-helmínticos em Haemonchus contortus e identificação de fatores de risco relacionados
(Universidade Federal de São Carlos, 2014-02-28)
Among the sheep parasites, Haemonchus contortus is the most prevalent and pathogenic nematode in tropical areas, causing huge economic losses. Alterations in the gene encoding the membrane P-glycoprotein (PgP) have been ...

(Universidade Federal de São Carlos, 2018-02-23)
The order Osteoglossiformes represent one of the most basal groups among the Teleosteos. These fishes live exclusively on freshwater environments and are characterized by the presence of a bonytongue. The group is a good ...
Investigação da diversificação e evolução cromossômica em espécies de Pimelodidae (Siluriformes): contribuição dos DNAs repetitivos e cromossomos B
(Universidade Federal de São Carlos, 2019-02-18)
Pimelodidae comprises 114 valid species, whith few of them are cytogenetically characterized, mainly, especially with respect to molecular cytogenetics. In addition, the species taxonomic delimitation is still very imprecise ...
