1. Description of immature stages and natural history of Stigmella schinivora (Lepidoptera: Nepticulidae), a leaf-miner associated with the Brazilian peppertree
ABSTRACT Stigmella schinivora van Nieukerken, 2016 was described from Cataratas de Iguazú, Misiones, Argentina, based on adults reared from Schinus terebinthifolius Raddi (Anacardiaceae) leaf mines. The aim of this study is to describe for the first time the external morphology of the immature stages of S. schinivora with the aid of light and scanning elect

2. Comparative morphoanatomical analysis of Mikania species
ABSTRACT Mikania belongs to the Asteraceae family and includes a wide range of promising pharmacological activities. Several species of Mikania, which is popularly known in Brazil as “guaco”, occur in Southern Brazil and their external morphology is similar. The aim of this study was to investigate the morpho-anatomical characteristics of the leaf and st

3. Comparative anatomy of leaves of Kalanchoe pinnata and K. crenata in sun and shade conditions, as a support for their identification
Kalanchoe pinnata (Lam.) Pers. and K. crenata (Andrews) Haw., Crassulaceae, are popularly used in the treatment of many diseases. Their biological activities, such as anti-leishmaniasis and analgesic, can be useful in phytotherapy. Both species are often misidentified as the other, because of their similar popular uses and names, and the similar external mor

4. Morphological and bioecological aspects of Epichrysocaris burwelli (Hymenoptera, Eulophidae) the gall wasp of Corymbia citriodora (Myrtaceae) leaves / Aspectos morfo-bioecológicos de Epichrysocharis burwelli (Eulophidae, Hymenoptera), vespa-das-galhas das folhas de Corymbia citriodora
This research deals with aspects of morphology, biology and ecology of Epichrysocaris burwelli a micro-wasp inducing galls on leaves of Corymbia citriodora, and recently introduced in Brazil. The following parameters were studied: percentage of galls on the leaf, time of adult emergence, adult longevity, sex ratio and characterization of the male, duration o

5. Revisão taxonômica do gênero Coleodactylus Parker, 1926 (Squamata, Sphaerodactylidae) / Taxonomic review of Coleodactylus genus Parker, 1926 (Squamata, Sphaerodactylidae)
Coleodactylus genus is widespread among the north of South America and assembles five species of dimunitive lizards that live in forests leaf-leather. The majority of studies regarding this genus do not consider morphological variations between species. Vanzolini (1967) made the last revision about this group. Species from this genus are known for being cryp

6. Padrão de venação e epiderme foliar de espécies de lauraceae juss do Distrito Federal, Brasil
Eighteen Lauraceae species, occurrent in Distrito Federal Brazil, had their leaf blades examined with the aim to assess the general characters usually considered in studies about epidermis and leaf architecture beyond proposing the use of additional characters. For the venation patterns analysis, some characters were proposed as well as the distancing betwee

7. Sistemática de Anthurium sect. Urospadix (Araceae) / Systematics of Anthurium sect. Urospadix (Araceae)
We present a phylogenetic analysis of Anthurium sect. Urospadix and related groups (Araceae). The genus has traditionally been considered taxonomically difficult and there has been little resolution of relationship within it. We performed parsimony analyses on morphological and molecular, and combined data sets. Anatomical characters have been used in classi

8. One Plant Actin Isovariant, ACT7, Is Induced by Auxin and Required for Normal Callus Formation
During plant growth and development, the phytohormone auxin induces a wide array of changes that include cell division, cell expansion, cell differentiation, and organ initiation. It has been suggested that the actin cytoskeleton plays an active role in the elaboration of these responses by directing specific changes in cell morphology and cytoarchitecture.
