| This is the first record of Acanthoscelides schrankiae Horn. feeding in seeds of Mimosa bimucronata (DC.) Kuntze. We investigated the pattern of oviposition and seed exploitation by A. schrankiae, and the distribution of mature fruits and seed predation in the inflorescences. We also compared the percentage of predated seeds, the total dry weight of fruits and non-predated seeds, the percentage of aborted seeds, and the percentage of non-emergent insects, among different quadrants of the M. bimucronata canopy. To determine the occurring species, the emergence of bruchids and parasitoids was observed in the laboratory, resulting altogether, only in individuals of A. schrankiae and Horismenus sp. (Hymenoptera: Eulophidae) species, respectively. Mean number... |

| Erythrina crista-galli L., Fabaceae, a medium-sized N-fixing tree, is native to flooding soils of several Brazilian biomes. Its cultivation has interest for ornamental and ecological restoration purposes. Information on seed coat dormancy is conflicting and inexact, therefore the present work aimed to verify it and to define methods for its overcoming. The study was composed by two experiments, using seed lots collected in different dates. Seeds were subjected to inducing germination treatments by chemical scarification (ACS commercial sulfuric acid, d=1,84 g/cm³) and thermic scarification (hot water). Results demonstrated high germination under acid scarification (up to 95%) and inferior when submitted to thermic scarification (reaching up to 43%);... |

| This study evaluated the morphological variation (total and commercial height, and diameter at 1.3 m above ground level - DBH) and environmental variables (slope, distance to water bodies, solar orientation, termites, tree damage and elevation) which influence production of oleoresin by Copaifera paupera (Herzog) Dwyer in southwestern Amazon. The present study was conducted at the experimental forest of Embrapa Acre, Rio Branco, Acre State, Brazil. Forty-seven trees with DBH ≥ 40 cm were mapped, of which 21.3% produced oleoresin immediately after being drilled and 53.2% produced oleoresin after 5 to 7 days, totaling 74.5% productive trees. The site slope was the only variable that significantly influenced oleoresin production; the greater the slope, the... |

| Abstract In this study we perform an inventory of the insect galls in savanna and forest sites of Hidrolândia, Goiás, Brazil. We found 150 insect gall morphotypes, distributed on 39 botanical families and 104 plant species. Among the insect galls, 81 gall morphotypes were recorded in the savanna site and 73 in the forest site. The plant taxa richest in insect galls were the family Fabaceae with 22 gall morphotypes, the genus Bauhinia (Fabaceae) with 15, and the species Siparuna guianensis (Siparunaceae) with seven gall morphotypes. We found gall-inducing insects belonging to orders Diptera, Coleoptera, Lepidoptera and Thysanoptera. The galling insects of family Cecidomyiidae (Diptera) were the most common inducing 48.1% of the gall morphotypes. This is the... |

| ABSTRACT In the present paper we investigated the insect gall distribution along savanna and forest sites in the Floresta Nacional de Silvânia, Goiás, Brazil. The insect gall fauna was surveyed bi-monthly between December 2009 and June 2010. In total we found 186 insect gall morphotypes, distributed on 35 botanical families and 61 plant species. Ninety-nine insect gall morphotypes were recorded in the forest and 87 in the savanna. Gall-inducing insects belonged to Coleoptera, Diptera, Hemiptera, Lepidoptera and Thysanoptera, with highlight to Cecidomyiidae (Diptera) that induced 34.1% of the gall morphotypes. Parasitoids and/or inquilines were recorded in 38 morphotypes, mainly from the families Eulophidae, Eurytomidae and Torymidae (Hymenoptera). Fabaceae... |

| After a fire event, germination of seeds with hard coats can be enhanced. In the present study, we investigated whether germination of Mimosa bimucronata (DC.) Kuntze (Fabaceae) seeds, which present hard coats, is increased after fire, even though these trees usually occur in damp areas, where fire is a transient event. Fire events were manipulated in trays filled with soil covered with different amounts of dry grasses, characterizing three treatments: a) 0g (control group); b) 300g, and c) 450g of dry grass. Burning treatments were applied to seeds positioned either on the soil surface or buried in the soil. Germination experiments were carried out at 0-h and 24-h after fire to obtain the germination percentage and the Germination Speed Index (GSI). For... |

| Frutos e sementes de Tipuana tipu foram analisados morfo-anatomicamente, durante seu desenvolvimento, objetivando descrever sua estrutura, esclarecer a origem da ala pericárpica e verificar a ocorrência de poliembrionia, hipótese levantada a partir de dados de literatura. Para tanto, preparou-se o laminário segundo técnicas convencionais e foram observados morfologicamente os embriões das sementes obtidas de 100 frutos. O fruto de T. tipu é uma sâmara, cuja ala se desenvolve a partir da região látero-apical do ovário e lateral do estilete, já estando delineada no ovário de botões florais jovens. As sementes, provenientes de óvulos bitegumentados, são unitegumentadas e testais. A testa não exibe a estrutura característica do tegumento das leguminosas, como... |

| Os pulvinos, estruturas responsáveis por movimentos foliares, rápidos ou lentos, em resposta a estímulos externos ou endógenos, constituem uma característica marcante das leguminosas. Os ajustes no posicionamento foliar representam um mecanismo eficiente que permite a maximização da fotossíntese em condições adversas. Na literatura disponível, a maioria das informações sobre a estrutura de pulvinos refere-se a poucas espécies de leguminosas, especialmente aquelas que apresentam movimentos rápidos. Neste trabalho é descrita a anatomia do pulvino primário de nove espécies de leguminosas nativas do cerrado com diferentes tipos e velocidades de movimento foliar, buscando identificar padrões e apontar peculiaridades estruturais. O pulvino primário das espécies... |
