1. Diversidade de fungos zoospóricos da Reserva Biológica de Mogi Guaçu, estado de São Paulo, Brasil
Realizou-se o levantamento da diversidade de fungos zoospóricos em duas áreas de Cerrado, com estados de preservação distintos, na Reserva Biológica de Mogi Guaçu, estado de São Paulo. Quatro coletas trimestrais de água e solo foram realizadas em seis pontos por área, durante as estações chuvosa (janeiro e outubro de 2008) e seca (abril e julho de

2. Blastocystis hominis Brumpt 1912 (Chromista: Blastocystea) em cães e gatos de domicílios localizados na região Metropolitana do Rio de Janeiro / Blastocystis hominis Brumpt, 1912 (Chomista: Blastocystea) in housed dogs and cats from Metropolitan Region of Rio de Janeiro
Com o objetivo de determinar a morfologia, freqüência, influência da idade e sexo, e fatores de risco associados à Blastocystis hominis nas fezes de cães e gatos domiciliados na Região Metropolitana do Rio de Janeiro, foram coletadas amostras fecais por conveniência de 175 cães e 59 gatos. Para o diagnóstico de B. hominis, foi utilizado o exame dire

3. The single, ancient origin of chromist plastids
Algae include a diverse array of photosynthetic eukaryotes excluding land plants. Explaining the origin of algal plastids continues to be a major challenge in evolutionary biology. Current knowledge suggests that plastid primary endosymbiosis, in which a single-celled protist engulfs and “enslaves” a cyanobacterium, likely occurred once and resulted in t

4. Kingdom protozoa and its 18 phyla.
The demarcation of protist kingdoms is reviewed, a complete revised classification down to the level of subclass is provided for the kingdoms Protozoa, Archezoa, and Chromista, and the phylogenetic basis of the revised classification is outlined. Removal of Archezoa because of their ancestral absence of mitochondria, peroxisomes, and Golgi dictyosomes makes

5. Developments in Fungal Taxonomy
Fungal infections, especially those caused by opportunistic species, have become substantially more common in recent decades. Numerous species cause human infections, and several new human pathogens are discovered yearly. This situation has created an increasing interest in fungal taxonomy and has led to the development of new methods and approaches to funga

6. Chimeric conundra: are nucleomorphs and chromists monophyletic or polyphyletic?
All algae with chloroplasts located not freely in the cytosol, but inside two extra membranes, probably arose chimerically by the permanent fusion of two different eukaryote cells: a protozoan host and a eukaryotic algal symbiont. Two such groups, cryptomonads (phylum Cryptista) and Chlorarachniophyta, still retain a DNA-containing relic of the nucleus of th
