Esse estudo buscou informacoes sobre o processo reprodutivo de cinco especies arboreas com diferentes caracteristicas ecologicas, no contexto da Exploracao de Impacto Reduzido (EIR): Jacaranda copaia (Aubl.) D. Don (Bignoniaceae), Dipteryx odorata (Aubl.) Willd. (Leguminosae - Papilionoidae), Carapa guianensis Aubl. (Meliaceae(, Symphonia globulifera L.f. (Clusiaceae) e Bagassa guianensis Aubl. (Moraceae). 
FENOLOGIA REPRODUTIVA DA ESPÉCIE Carapa guianensis Aubl. (ANDIROBEIRA) EM ECOSSISTEMAS DE TERRA FIRME E VÁRZEA, AMAPÁ, BRASIL.
The aspects phenology of Carapa guianensis Aubl. are presented, related to the precipitation pluviometric of the region, in two ecosystems of natural occurrence of the species. The period of monthlyExpand
FENOLOGIA REPRODUTIVA DE Bertholletia excelsa Bonpl. EM FLORESTA DE TERRA FIRME EM MAZAGÃO, AMAPÁ.
TLDR
A disseminacao de frutos coincidiu com o desenvolvimento dos mesmos, obtendo maior desenVOLVimento na estacao chuvosa, com pico no mes of fevereiro. Expand
Pollen morphology of Carapa species (Meliaceae) from the Brazilian Amazon
TLDR
It was found that the three Carapa species present little variations in pollen morphology, and Carapa vasquezii has higher values for the length and width of endoaperture; however, it has lower values for polar and equatorial diameter. Expand
Parâmetros do sistema reprodutivo em uma população de alta densidade de andirobas na Floresta Amazônica
TLDR
Results sugerem that, para manter um tamanho efetivo minimo de 150 individuos, para melhoramento, conservacao genetica e programas de reflorestamento ambiental, sementes de pelo menos 56 arvores devem ser coletadas. Expand
Control of Carapa guianensis phenology and seed production at multiple scales: a five-year study exploring the influences of tree attributes, habitat heterogeneity and climate cues
TLDR
Climatic cues were central to setting overall patterns in reproductive activity and seemed to best explain why years with high seed production were consistent across the two forest types examined. Expand
Diversidade genética de populações de andiroba no Baixo Acre
TLDR
The genetic diversity of two Carapa guianensis Aubl.(crabwood) populations, in the Tate of Acre, Brazil, and to compare the diversity estimations with those obtained in other populations of the species are evaluated, showing that inbreeding does not occur in these populations. Expand
O MERCADO DE AMÊNDOAS DE Dipteryx odorada (CUMARU) NO ESTADO DO PARÁ
The study aimed to present the results of a market study of  cumaru  nuts in the State of Para, for the 2005 harvest. The data used in the research were obtained at the Brazilian Institute ofExpand
Explosive pollen release, stigma receptivity and pollen dispersal pattern of Boehmeria caudata Sw. (Urticaceae) in a Brazilian rain forest
TLDR
Be Beetles and halictid bees were observed feeding on pollen from staminate flowers, but probably did not affect pollination because they did not seem to visit pistillate flowers. Expand
Pollen Dispersal Patterns in a Fragmented Population of Carapa nicaraguensis (Meliaceae)
TLDR
The results are consistent with those of previous studies indicating that pollen-dispersal patterns are dependent on the degree of isolation and tree density of local populations. Expand
Mating system and genetic diversity of progenies before and after logging: a case study of Bagassa guianensis (Moraceae), a low-density dioecious tree of the Amazonian forest
TLDR
Investigation of the impact of logging on mating system and genetic diversity of the low-density, thrip-pollinated, dioecious tree Bagassa guianensis within a 500-ha plot at Tapajós National Forest, Pará State, Brazil finds that the loss of alleles in the population was compensated by the higher heterogeneity in the pollen pool after the removal of the largest trees by logging.
