1. Revisão das espécies de Macrobrachium, Bate, 1868, pertencentes ao complexo M. olfersii (Crustacea, Palaemonidae): análises morfológicas e moleculares / Revision of species from Macrobrachium, Bate, 1868, that belonging M. olfersii complex (Crustacea, Palaemonidae): morphologic and molecular analysis.
Pesquisas envolvendo a sistemática e a taxonomia de camarões de água doce do gênero Macrobrachium Bate, 1868 ainda são pouco elucidativas para alguns de seus membros. Este é o caso de Macrobrachium olfersii (Wiegmann, 1836) que ocorre desde o sudeste dos Estados Unidos até o sul do Brasil e é comumente confundido com espécies que ocorrem preferencia

2. Diversidade cromossômica e molecular no gênero Astyanax (Characiformes: Characidae) / Chromosomal and molecular diversity in the genus Astyanax (Characiformes: Characidae)
The origin of the genus Astyanax, one of the most specious genera of the family Characidae is appointed as polyphyletic, with its current taxonomic status Incertae sedis.Morphologic, genetic and phylogeographic studies contribute to a better knowledge on the genus, which is considered a model. In this work, several species of different locations were studied

3. Phylogeny and taxonomic revision of Pseudotrimezia (Iridaceae) / Filogenia e revisão de Pseudotrimezia (Iridaceae)
Several molecular phylogenetic studies focusing on Iridaceae contribute to confirm Trimezieae as a monophyletic group. Despite that, the tribe is poorly characterized and lacks morphological synapomorphies as support. On the other hand, Pseudotrimezia is morphologically well characterized, but its monophyly has never been investigated. Anatomical studies car

4. Morphological variation and mitochondrial DNA diversity in natural populations of Dendropsophus minutus (Anura: Hylidae) / Variabilidade genetica e relações interpopulacionais de Dendropsophus minutus do Brasil
In despite of its complex reproductive behavior, Dendropsophus minutus has a large distribution at East of Andes, South America and show high acoustic and morphologic diversity, suggesting that possibly more than one species may exist under this name. Its dorsum coloration has basically two main patterns, hourglass or bivittata. Here, 14 morphometric paramet

5. Phylogeny of Lamiales, with emphasis on Gratiolaceae species to Brazil / Filogenia molecular de Lamiales, com ênfase em espécies nativas de Gratiolaceae
The history of Scrophulariaceae has been characterized by different treatments regarding the circumscription of the family. Some proposals have included in the family groups currently recognized as belonging to families such as Globulariaceae, Lentibulariaceae, Orobanchaceae, Plantaginaceae e Selaginaceae. Tribe Gratioleae, traditionally included in Scrophul

6. O Complexo Cliona celata Grant, 1826 (Porifera, Demospongiae) na América do Sul: uma abordagem molecular e morfológica / The Cliona celata Grant, 1826 (Porifera, Demospongiae) complex in South America: a molecular and morphologic approach.
Este trabalho visou a averiguação do status taxonômico das esponjas bioerosivas do complexo Cliona celata da América do Sul por meio de técnicas moleculares, utilizando como marcadores a subunidade I da Citocromo c oxidase (cox1) e os Espaçadores Internos Transcritos do RNAr nuclear (ITS1 e ITS2), além de testar outros marcadores. Igualmente, avaliou

7. Sistemática de Anthurium sect. Urospadix (Araceae) / Systematics of Anthurium sect. Urospadix (Araceae)
We present a phylogenetic analysis of Anthurium sect. Urospadix and related groups (Araceae). The genus has traditionally been considered taxonomically difficult and there has been little resolution of relationship within it. We performed parsimony analyses on morphological and molecular, and combined data sets. Anatomical characters have been used in classi
