.The Amazon basin is covered by the most species‐rich forests in world and considered to house many endemic tree species. Yet, Amazonian ecosystems lack reliable estimates of their degree endemism, causes diversity endemism are intense matters debate. We reviewed spatial distribution 658 important flood‐tolerant white‐water (várzea) species across entire Neotropics using data from herbaria, floras, inventories checklists. Our results show that 90% várzea partially or widely distributed...
In the context of 200th anniversary Charles Darwin's birth in 1809, this study discusses variation structure and adaptation associated with survival reproductive success face environmental stresses trees tropical floodplains. We provide a comparative review on responses to flooding stress freshwater wetlands environments. The four large we evaluate are: (i) Central Amazonian floodplains South America, (ii) Okavango Delta Africa, (iii) Mekong Asia (iv) Northern Australia. They each have...
Abstract Amazonia’s floodplain system is the largest and most biodiverse on Earth. Although forests are crucial to ecological integrity of floodplains, our understanding their species composition how this may differ from surrounding forest types still far too limited, particularly as changing inundation regimes begin reshape tree communities critical ecosystem functions they underpin. Here we address gap by taking a spatially explicit look at Amazonia-wide patterns tree-species turnover...
In the Central Amazonian floodplains, several hundred tree species grow in areas that are periodically flooded by nutrient-rich white-water rivers (várzea) and nutrient poor black-water (igapó). Seed masses of 31 from várzea 27 igapó were compared taking into consideration their taxonomic relatedness. Overall average seed mass was higher (mean = 7.08 g) nutrient-poor than 1.16 g). igapó, growing at high elevations on flooding gradient had significantly low elevations. várzea, no difference...
The major rivers of the Amazon River basin and their biota are threatened by planned construction large hydroelectric dams that expected to have strong impacts on floodplain plant communities. present study presents forest inventories from three sites colonized alluvial riparian vegetation in Tapajós, Xingu Tocantins basins eastern Amazonian. Results indicate tree species highly specialized clearly distinct among river basins, although they not very each other environmental constraints...
Secondary plants may be added to a cropping system for the purpose of improving pest control. In recent article (Parolin P, Bresch C, Brun R, Bout A, Boll Desneux N, Poncet C (2012) used in biological control: review, International Journal Pest Management 58, 91–100) we defined different categories secondary enhance companion, repellent, barrier, indicator, trap, insectary, and banker are intentionally agricultural systems order improve management through either top-down or bottom-up...
Construction of hydroelectric dams in tropical regions has been contributing significantly to forest fragmentation. Alterations at edges fragments impact plant communities that suffer increases tree damage and dead, decreases seedling recruitment. This study aimed test the core-area model a fragmented landscape caused by construction power Brazilian Amazon. We studied variations structure between margin interiors 17 islands 8-100 hectares Tucuruí dam reservoir, two plots (30 >100m from...
Abstract Question The encroachment of woody species has been globally reported over much arid and semi‐arid biomes, associated with a decrease in cover number herbaceous species. How does the shrub affect community structure composition grasslands wetland ecosystem? Location Seasonally flooded Neotropical Hyperseasonal Savanna, Pantanal wetland, Brazil. Methods We investigated effect encroaching plant Combretum laxum on from seasonally using 29 vegetation samples representing at different...
ABSTRACT Sediment‐rich rivers seasonally flood central Amazonian várzea forests, leading to periodic anoxic conditions in the rhizosphere and requiring morphological structural adaptations, such as aboveground root systems. We investigated some possible relationships between types environmental factors forest plots covering 3.1 ha of Mamirauá Sustainable Development Reserve, Brazil. Digital elevation models study sites were obtained; sedimentation soil texture check relationship position...
In the Amazonian floodplains plants withstand annual periods of flooding which can last 7 months. Under these conditions seedlings remain submerged in dark for long since light penetration water is limited. Himatanthus sucuuba a tree species found 'várzea' (VZ) and adjacent non-flooded 'terra-firme' (TF) forests. Biochemical traits enhance flood tolerance colonization success H. periodically flooded environments were investigated. Storage carbohydrates seeds VZ TF populations extracted...
