Fragmentos de Floresta Ombrófila Mista têm sido freqüentemente utilizados para o manejo bovinos na região do médio rio Pelotas, Sul Brasil. Para avaliar efeito dos animais estrutura populacional Araucaria angustifolia, Clethra scabra, Dicksonia sellowiana e Maytenus ilicifolia, foram amostrados sítios, sujeitos à alta baixa intensidade pastoreio, em cinco fragmentos, utilizando-se parcelas 20 x m. Apesar pequeno tamanho fragmentos da perturbação pelo gado pela extração seletiva madeira, as...
To understand the growth and reproduction of palm Geonoma schottiana in gallery forest Central Brazil, two hypotheses were raised: (i) production leaves reproductive structures are concentrated period year with high light availability; (ii) leaf activity related to plant length. However, it is expected that senility effects will cause fast reduction activities higher plants. Growth dry season, when insolation than wet suggesting inflorescence on G. understory more limited by soil humidity....
O artesanato de hastes florais capim-dourado Syngonanthus nitens , Eriocaulaceae) costuradas com as fibras folhas-jovens buriti ( Mauritia flexuosa Arecaceae) tornou-se simbolo da regiao do Jalapao e mesmo todo o estado Tocantins na ultima decada. Alem extrativismo vegetal, esta importante atividade economica envolve uso fogo para estimulo floracao capim-dourado. Este artigo sintetiza resultados estudos etno-ecologicos desenvolvidos em cooperacao comunidades rurais gestores ambientais entre...
PREMISE OF THE STUDY: The reproduction and growth of large palms are influenced by many factors, including light plant size, but few studies have examined smaller species (up to 2 m tall). We the effect incident individual size on rates, probability reproduction, number inflorescences three small palm compared two methods for estimating canopy openness. METHODS: measured openness above crowns 132 adult plants in centers 72 subplots (10 × 10 m) where individuals were sampled. also recorded...
Abstract: Plant populations can respond to temporal environmental heterogeneity caused by natural disturbances, such as herbivory. Palm individuals of several species are preyed upon mammals, but the effects herbivory events on population dynamics remain poorly known. To evaluate stochasticity a Geonoma schottiana (Arecaceae) population, we surveyed annually 40 permanent 20 × 10-m plots in riparian tropical forest over 5 y (2000–2004) and results were analysed using matrix models. The growth...

Patterns of species diversity are essential to understand community structure. We aimed determine and patterns beta in different spatial scales. sampled three thousand individuals between the coordinates 22°10'S 22°16'S 47°47'W 48°00'W assess scales (maximum distances 80 m, 1,400 12,000 m), using point-centered-quarter method. partitioned gamma into alpha components. Beta was dissimilarities produced by turnover nestedness. The contribution greater than that all scales, although were similar...

Land cover change threatens biodiversity by reducing epiphyte species richness, altering composition, and favoring generalist species. Pastures can effectively mitigate the structural differences from forests maintaining scattered trees retaining a significant portion of regional diversity. We explore negative effects land potential factors promoting similarity between pastures. hypothesize that pasture assemblages are characterized low richness dominated xerotolerant species; with...
A competição interespecífica é um dos processos ecológicos mais importantes para a coexistência de espécies. Em comunidades arbóreas, morte indivíduos da espécie competitivamente fraca leva à relação espacial dissociação entre populações espécies competidoras. Além disso, pode haver redução no crescimento das plantas nas proximidades competidores fortes. Normalmente, os efeitos são intensos filogeneticamente próximas devido sua similaridade funcional. Para testar se arbóreas importante...
