13. Analise filogenetica da familia Teiidae (Squamata, Reptilia), a ultra-estrutura de espermatozoide e a sua utilidade filogenetica
Several studies have attempted to clarify the relationship among the teiid genera, based on several types of morphological data sets. Therefore, the relationships among teiid genera are not completely solved. Increase the number of characters, using new sources of characters, the sperm ultrastructure, and additional traditional morphological characters such

14. Ecologia geografica de Tropidurus torquatus (Squamata : Tropiduridae) em areas de restinga da costa sudeste e sul-nordeste do Brasil : aspectos reprodutivos, ecologia termica e comunidades de nematodeos associados
Studies of geographical ecology can detect variation in a species ecological attributes along its geographical range, and determine the extent to which historical factors and/or local environmental factors can explain such variations. The wide geographic distribution of the tropidurid lizard Tropidurus torquatus makes it a good model for geographical ecology

15. Quelonios, jacares e ribeirinhos no Parque Nacional do Jau (AM)
Quelônios e jacarés são recursos historicamente utilizados pelos moradores das florestas das planícies inundáveis da Amazônia. Ribeirinhos, obtém a maior parte da proteína capturando vertebrados aquáticos, sobretudo peixes. Mas quelônios e jacarés são importantes fontes de carne renda. Os rios de água preta e as terras que drenam tem baixo poten

16. Estudo ultraestrutural de espermatozoide de squamata (Reptilia), e sua importancia na analise filogenetica
The phylogenetic analysis based on sperrn ultrastructure has proved to be very interesting to cellular and systematics biologists. This interest stems from the fact that the sperrn ultrastructure provides an important new and non-traditional source of data, evolutionarily more conservative than the morphological characters traditionally used and, hence, this
