1. Morfologia, anatomia e histoquímica de Noteroclada confluens Taylor ex Hook.Wilson (Pelliaceae, Marchantiophyta) / Morphology, anatomy and histochemistry of Noteroclada confluens Taylor ex Hook. & Wilson (Pelliaceae, Marchantiophyta)
Noteroclada confluens Taylor ex Hook. & Wilson é uma hepática de aparência folhosa, pertencente à família Pelliaceae (Marchantiophyta). Ocorre predominantemente em regiões montanhosas, declives e locais próximos à córregos, em solos argilosos. O presente estudo teve por objetivo descrever a morfologia, anatomia e histoquímica das estruturas do game

2. Inventário de espécies de pteridófitas de uma mata de galeria em Alto Paraíso, Goiás, Brasil e morfogênese dos gametófitos de Pecluma ptilodon (Kunze) Price e Campyloneurum phyllitidis (L.) C. Presl (Polypodiaceae)
This work presents a survey of pteridophytes species established in a Galery Forest, located in the right margin of Couros river, inside the Portal das Chapadas farm, in Alto Paraiso de Goiás country (140988S, 473597W, 1,164m in high), in the region known by Chapadas dos Veadeiros. The samples were collected at 15-day intervals, between June 2006 and June 2

3. Life history of Coelomomyces psorophorae.
The mosquito parasite, Coelomomyces psorophorae (Blastocladiales, Chytridiomycetes) alternates obligately between the larvae of Culiseta inornata and the copepod Cyclops vernalis. Isogametes, derived from heterothallic, wall-less gametangia which develop in the copepod, fuse to produce a diploid zygote that subsequently infects the mosquito host. Zoospores f

4. Mitochondrial DNA rearrangements of Podospora anserina are under the control of the nuclear gene grisea
Podospora anserina is a filamentous fungus with a limited life span. Life span is controlled by nuclear and extranuclear genetic traits. Herein we report the nature of four alterations in the nuclear gene grisea that lead to an altered morphology, a defect in the formation of female gametangia, and an increased life span. Three sequence changes are located i

5. Life history biology of early land plants: Deciphering the gametophyte phase
The ca. 400-million-year-old Rhynie chert biota represents a benchmark for studies of early terrestrial ecosystems. The exquisite preservation of the organisms documents an ancient biodiversity that also includes various levels of biological interaction. Absent from the picture until recently has been detailed information about the development of the gametop
