1. Leaf structural traits of three species of Qualea Mart. (Vochysiaceae) in a cerradão area in the Cerrado-Amazonian Forest transition
Resumo Qualea é um gênero comumente encontrado em diferentes fisionomias do cerrado brasileiro, crescendo em ecossistemas abertos até áreas florestais fechadas, sujeitos à alta irradiância, incêndios, baixa disponibilidade de nutrientes e deficit hídrico sazonal. Comparam-se aqui, atributos estruturais foliares de Qualea grandiflora Mart., Qualea mul

3. Epidermal morphology of the cordaitalean leaf Noeggerathiopsis brasiliensis nom. nov. from the southern Paraná Basin (Lower Permian, Rio Bonito Formation) and paleoenvironmental considerations
Abstract A Brazilian cordaitalean leaf is reassigned and redescribed based on cuticular analysis. The new name Noeggerathiopsis brasiliensis is erected as a replacement for Rufloria gondwanensis Guerra-Sommer. The leaf adpressions come from a tonstein layer within a Sakmarian coal seam of the Faxinal Coalfield, southern Paraná Basin, Brazil (U-Pb SHRIMP mea

5. Permineralized conifer-like leaves from the Jurassic of Patagonia (Argentina) and its paleoenvironmental implications
Abstract Abstract: Anatomically preserved conifer-like leaves from the Middle Jurassic La Matilde Formation at the Barda Blanca locality in the Gran Bajo de San Julián area, southern Patagonia are described here. Leaves are assigned to conifers based on the following foliar features: thick-walled epidermal cells, a sclerenchymatic hypodermis, resin canals a

6. Cd-tolerance markers of Pfaffia glomerata (Spreng.) Pedersen plants: anatomical and physiological features
Physiological and anatomical features of Cd-tolerance in Pfaffia glomerata were examined by exposing plantlets to nutrient solutions with increasing Cd concentrations (0, 15, 45, and 90 µmol Cd L-1), and possible Cd-tolerance markers were established. Cd contents were found to be higher in roots than in shoots. According to the bio-concentration factor data

7. Anatomia ecolÃgica foliar de espÃcies da caatinga / Leaf anatomy of species of ecological caatinga
In semiarid environments water availability is a main limiting factor for plants. A combination of characteristics can contribute to saving water, including the anatomical ones. The anatomical attributes often associated with environments of water restriction are called xeromorphic. The leaves are organs commonly exposed to sunlight which have large areas of

8. Impactos climáticos regionais da mudança de vegetação no semi-árido do nordeste brasileiro / Impacts climatics regionals of the change vegetation in the simi-arid in the northeast Brazil
In the present study the regional climatic impacts due to the vegetation changes were evaluated, through long term numerical simulations with the regional Eta/SSiB model of the CPTEC/INPE, in which modifications were included to operate in climatic mode. The work was accomplished in two phases. In Phase I, it was evaluated the climatic change of the Northeas

10. Foliar anatomy of species of Chamaecrista Moench. (Leguminosae/Caesalpinioideae) occurring in rupestrial fields / Anatomia foliar de espécies de Chamaecrista Moench. (Leguminosae/Caesalpinioideae) ocorrentes em campo rupestre
Minas Gerais state flora presents different biomas but little is known about the diversity of its species, some of which secrete natural compounds having well-known biological activity. There is a large number of species of recognized economic interest in the Leguminosae family and in the rupestrial fields of Minas Gerais, totaling 28 of the 351 species incl

11. As especies do genero Vochysia Aubl.(Vochysiaceae) ocorrentes no Estado de São Paulo
Taxonomic studies of the species of the genus Vochysia Aublet (Vochysiaceae), which occur in the state of São Paulo, Brazil, based on herbarium material and field observations, are presented. They comprise 12 species: four from cerrado, V. cinnamomea, V. rufa and V. sessilifolia, of the sect. Vochysiel/a, and V. thyrsoidea, of the sect. Ciliantha; and eight
