1. Morpho-anatomical characteristics of Baccharis glaziovii in support of its pharmacobotany
Baccharis glaziovii Baker, Asteraceae, also known as carqueja or carqueja-arbustinho, is a native shrub of Brazil that reaches 0.5-2.5 m in height. It is a dioecious species that blossoms from September to December. This species has cladodes, which are winged stems that belong to the “carquejas” and are widely used indiscriminately by the population due

2. Morphological and molecular diagnostics for plant-parasitic nematodes: working together to get the identification done
Nematodes are considered one of the most difficult organisms to identify due to their microscopic size, morphological similarity, limited number of distinguishable taxonomic characters and overlapping morphometric measurements. However, there are few trained nematode taxonomists remaining, primarily due to retirement without replacement and/or young scientis

3. Biossistematica das especies do complexo Anemopaegma arvense (Vell.) Stellf. ex de Souza (Bignoniaceae, Bignonieae) : aspectos anatomicos, citologicos, moleculares, morfologicos e reprodutivos / Biossystematics of the Anemopaegma arvense (Vell.) Stellf. ex de Souza complex (Bignoniaceae, Bignonieae) : anatomical, cytological, molecular, morphological and reproductive aspects
Anemopaegma arvense complex is constituted by species and varieties of difficult delimiting. Taxonomists opinions based upon morphologic features are controversial as to considering them either an only highly polymorphic species or separating them into different taxa. In order to help with the circumscription of such taxa, a biosystematic study was conducted

4. Taxonomia e filogenia de microssimbiontes de feijoeiro (Phaseolus vulgaris L.) com o uso da metodologia de MLSA (multilocus sequence analysis)
Os rizóbios são bactérias que vivem em simbiose com algumas leguminosas. Atualmente, a filogenia dos rizóbios, assim como de outros procariotos é baseada, principalmente, no gene ribossomal 16S, embora alguns estudos tenham demonstrado que os genes ribossomais podem, ocasionalmente, sofrer transferência lateral e recombinação genética, fazendo com q

5. Revisão taxonomica e analise cladistica do genero Dichorisandra J.C. Mikan (Commelinaceae) / Taxonomic revision and cladistic analysis of Dichorisandra
The neotropical genus Dichorisandra is the largest within the subtribe Dichorisandrinae, being characterized by its poricidal anthers (sometimes opening by slits but functionally poricidal) and its arillated seeds. The plants are perennial, herbaceous, sometimes with a leaf rosette close to the ground, and live mostly within forests. The last revision of the

6. Invertebrados de cavernas do Distrito Federal: diversidade, distribuição temporal e espacial
There are 4,153 registered caves in Brazil, but most cave studies has been done by observant cavers rather than part of surveying programs. A correlate problem is the lack of ertebrates were sampled by active seach (hand collecting and the register of rganisms) and by baited pitfall traps. The number of traps varied among caves due to their morphological and
