Abstract Wood density is a critical control on tree biomass, so poor understanding of its spatial variation can lead to large and systematic errors in forest biomass estimates carbon maps. The need understand how why wood varies especially tropical America where forests have exceptional species diversity turnover composition. As identity composition are challenging estimate remotely, ground surveys essential know the trees, whether measured directly or inferred from their identity. Here, we...
Abstract We describe the patterns of composition and abundance tree species their relationships to environmental factors in an area affected by Jirau hydroelectric dam on Madeira River Brazilian state Rondônia. Trees were sampled 20 1‐ha forest plots distributed among areas unaffected reservoir. Predictors distribution included analyses soil fertility (sum bases) texture, slope, vertical distance from nearest drainage. 8504 individuals belonging 909 species/morphospecies. Floristic...
Abstract Forest responses to changes in drought frequency is a critical matter for the future of Amazon forests under climate change, but equally important much less studied response large floods, which may also increase tree mortality and change forest functionality. Further, vulnerability flood being exacerbated by hydroelectric dams on rivers that put upland environments not adapted at unique risk. To address this knowledge gap, we evaluated effects extreme 2014 rainfall coupled with...
This study provides a checklist of the phanerogams and pteridophytes Tocantins river middle basin, in northern Goiás state southern state, Brazil. Herbarium samples were collected from 2000 to 2009 this floristic survey recorded 1572 species 135 families. The most species-rich families Fabaceae (217), Poaceae (116), Asteraceae (88), Euphorbiaceae (65), Orchidaceae (58) Malpighiaceae (56). Furthermore, 14 endangered 31 rare recorded, mainly associated with campos rupestres Veadeiros Plateau...
Extreme weather events and the presence of mega-hydroelectric dams, when combined, present an emerging threat to natural habitats in Amazon region. To understand magnitude these impacts, we used remote sensing data assess forest loss areas affected by extreme 2014 flood entire Madeira River basin, location two mega-dams. In addition, plots (26 ha) were monitored between 2011 2015 (14,328 trees) order evaluate changes tree mortality, aboveground biomass (AGB), species composition community...
O objetivo do estudo foi avaliar a estrutura populacional e os efeitos da intensidade luminosa no recrutamento de jatobá-da-mata (Hymenaea courbaril L.) em dois fragmentos Mata Galeria não-inundável, com diferentes graus perturbação antrópica. Foi assumida hipótese que as populações diferem nas classes tamanho (diâmetro altura) abundância dos indivíduos entre o responde às diferenças luminosidade disponível sub-bosque. Como espécie clímax dependente luz amplamente distribuída adaptada...
As árvores nas cidades trazem benefícios como melhorias na paisagem, proporcionando ambientes que favorecem o convívio social e a relação do homem com natureza, assim equilíbrio entre as áreas verdes concreto encontrado cidades. Porém, uma arborização utilização de espécies inadequadas ao espaço urbano, porte muito grande ou susceptível aos ventos, pode trazer problemas, queda grandes galhos, causam prejuízos materiais acidentes. Este estudo foi realizado no Centro Ciências Agroveterinárias...
