A colonização de uma área por espécies de abelhas sem ferrão. Um estudo de caso: Partamona helleri (Friese, 1900) (Hymenoptera : Apidae: Meliponini)
(Universidade Federal de São Carlos, 2011-02-28)
Bees are obligatory floral visitors and are considered the main pollinators of angiosperms. The increasing interest in the services of bees has led to efforts to develop management strategies for conservation purposes. The ...
Origem das linhagens mitocondriais nas abelhas africanizadas (Apis mellifera L.) do Brasil
(Universidade Federal de São Carlos, 2012-03-30)
The Africanization process of Apis mellifera has raised several questions about the genetic makeup of resulting populations. This study aimed to identify the number, frequency and distribution of different mitochondrial ...
Clonagem gênica e caracterização de uma enzima tipo-luciferase de coleópteros não bioluminescentes e sua relação com a origem da atividade luminescente
(Universidade Federal de São Carlos, 2012-03-06)
Bioluminescence in beetles is dependent on luciferase which evolved from AMP/CoA ligases. The cDNA of a luciferase-like enzime was cloned from the Malpighian tubules of Zophobas morio mealworm (Coleoptera: Tenebrionidae). ...

(Universidade Federal de São Carlos, 2012-02-17)
The destruction of ecosystems and their fragmentation are major environmental problems, being biodiversity conservation one of biggest challenges today .These processes result in the reduction and isolation of populations, ...
Expressão recombinante e caracterização de uma endoxilanase não descrita de Trichoderma harzianum
(Universidade Federal de São Carlos, 2012-06-29)
The use of alternative and renewable fuels is vital to solve the problems derived from the dependence of fuels, and the vegetal biomass is the only renewable source available in large scale that can be converted in energy. ...
Efeitos epigenéticos sobre a diferenciação in vitro de mioblastos e a expressão dos genes CAST e CAPN1 em bovinos
(Universidade Federal de São Carlos, 2013-09-20)
Epigenetics can be defined as the study of heritable changes in phenotype without the occurrence of changes in nucleotide sequence. Epigenetic modifications occur by the chemical changes in DNA and their associated proteins, ...
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 ...
