Fitossociologia de um trecho da mata ciliar do rio da Prata, Jardim, MS, Brasil
Provedor de dados: Acta Botanica Brasilica
Autores: Battilani,Joanice Lube; Scremin-Dias,Edna; Souza,Andréa Lúcia Teixeira de.
O presente estudo teve como objetivos descrever a riqueza e a diversidade em espécies e analisar os aspectos fitossociológicos de um trecho da mata ciliar do rio da Prata, localizado na Fazenda Nossa Senhora Aparecida no município de Jardim, MS. Seis transectos de 150 m cada foram distribuídos aleatoriamente perpendiculares à margem do rio e subdivididos em 90 parcelas de 10 m×10 m. Em cada parcela foram amostrados todos os indivíduos com diâmetro à 1,30 m de altura do solo (DAP) &gt; 3,18 cm, totalizando 661 indivíduos pertencentes a 33 famílias, 57 gêneros e 66 espécies. As famílias Meliaceae, Mimosaceae, Sapindaceae, Euphorbiaceae, Fabaceae, Myrtaceae e Rutaceae destacaramse pelo elevado número de espécies. Myrcianthes pungens (O. Berg) D. Legrand,...

Structural features of species of Asteraceae that arouse discussions about adaptation to seasonally dry environments of the Neotropics
Provedor de dados: Acta Botanica Brasilica
Autores: Ferraro,Alexandre; Scremin-Dias,Edna.
ABSTRACT Seasonally-dry environments of the Neotropics, such as the South American Chaco, exert selective pressures on vegetation through a pronounced water deficit. We describe the underground system and leaf anatomy of three species of Asteraceae from the Brazilian portion of the Chaco (Pterocaulon purpurascens Malme, Wedelia trichostephia DC., and Pectis gardneri Baker), aiming to describe their structural and adaptive features using standard plant anatomy techniques. Pterocaulon purpurascens and W. trichostephia exhibited slightly thickened xylopodia, with gemmiferous character and self-grafted stem shoots; Pectis gardneri displayed a slightly-thickened tuberous root with storage substances. Longitudinal sequences of cells with highly thickened walls...

Meristematic activity of the Endodermis and the Pericycle in the primary thickening in monocotyledons: considerations on the "PTM"
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Menezes,Nanuza L. de; Silva,Delmira C.; Arruda,Rosani C.O.; Melo-de-Pinna,Gladys F.; Cardoso,Vanessa A.; Castro,Neuza M.; Scatena,Vera L.; Scremin-Dias,Edna.
This paper proposes a new interpretation for primary thickening in monocotyledons. The anatomy of the vegetative organs of the following species was examined: Cephalostemon riedelianus (Rapataceae), Cyperus papyrus (Cyperaceae), Lagenocarpus rigidus, L. junciformis (Cyperaceae), Echinodorus paniculatus (Alismataceae) and Zingiber officinale (Zingiberaceae). The endodermis with meristematic activity was observed in the root of all the species, in the stem of Cyperus, Cephalostemum and Lagenocarpus rigidus, and in the leaf trace of Cyperus and leaf of Echinodorus. Considering the continuity of tissues through the root, stem and leaf, the authors conclude that in the stem the pericycle remains active throughout the life of the plant as the generator of the...

Botanical Knowledge in the Law Enforcement: a Preliminary Approach Towards its Potential Use in Brazilian Criminal Caseworks
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Manvailer,Vinicius; Leandro,Thales D.; Scremin-Dias,Edna.
ABSTRACT We surveyed Brazilian forensic institutes in order to provide a baseline for botanical knowledge used in forensic applications. Our approach provides a better understanding of the law enforcement dynamics as a whole, and establishes perspectives and guidelines for implementing this discipline in Brazil, enhancing the elucidative power of Brazilian forensic institutes.
