Abstract The tropical forest carbon sink is known to be drought sensitive, but it unclear which forests are the most vulnerable extreme events. Forests with hotter and drier baseline conditions may protected by prior adaptation, or more because they operate closer physiological limits. Here we report that in South American climates experienced greatest impacts of 2015–2016 El Niño, indicating greater vulnerability temperatures drought. long-term, ground-measured tree-by-tree responses 123...
Abstract In tropical and highly diverse systems, Seed Dispersal Effectiveness (SDE) is a very useful approach to investigating the role of seed dispersers in one most important complex phases plants by analysing quantitative (QC) qualitative (QL) components dispersal process. Although fishes are recognized as an guild frugivores flooded environments, we still know little about effectiveness performed this group. Our study evaluated two subcomponents effectiveness, where used: (a) volume...
Abstract The response of plants to increasing atmospheric CO 2 depends on the ecological context where are found. Several experiments with elevated (eCO ) have been done worldwide, but Amazonian forest understory has neglected. As central Amazon is limited by light and phosphorus, understanding how responds eCO important for foreseeing will function in future. In a natural Central Amazon, we installed four open‐top chambers as control replicates another under (+250 ppm above ambient levels)....
For more than three decades, major efforts in sampling and analyzing tree diversity South America have focused almost exclusively on trees with stems of at least 10 2.5 cm diameter, showing highest species the wetter western northern Amazon forests. By contrast, little attention has been paid to patterns drivers largest canopy emergent trees, which is surprising given these dominant ecological functions. Here, we use a machine learning approach quantify importance environmental factors apply...
Abstract: Interactions between ants and non-myrmecochorous diaspores occur frequently on the forest floor results of these interactions (e.g. diaspore cleaning or removal) will often depend morpho-chemical characteristics diaspores. We conducted two different experiments with seven plant species in north-eastern Atlantic forest, Brazil. To evaluate whether ant decrease persistence time floor, we established sample stations by placing five each spaced every 10 m along a transect monitored...
Among invertebrates, ants are the most abundant and probably important seed dispersers in both temperate tropical environments. Crickets, also forests, omnivores commonly attracted to fruits on forest floor. However, their capability remove seeds has been reported only once. We compared Marantaceae removal by crickets assess role of as secondary Amazonia. Compared with ants, dispersed an equivalent number tended disperse larger farther. occurs mostly at night, suggesting that arillate floor...
As restingas são ambientes geologicamente recentes e as espécies que habitam típicas de ecossistemas adjacentes como Florestas Ombrófilas, Matas Tabuleiro a Caatinga, sendo este, o aspecto mais importante na sua composição espécies, é composta por diversas formas biológicas, tais árvores, arbustos, herbáceas eretas reptantes. O estudo foi realizado no Município Mata São João vila Praia do Forte, localizada ao longo Litoral Norte Estado da Bahia. Com objetivo avaliar se há existência...
Due to the current rhythm of ecosystem destruction, development new techniques aiming at conservation forest remnants and their biota is urgent. Our objective was compare two leaf-litter translocation (with without withdrawing pre-extent litter layer), through observations on spider ant richness assemblage composition, in order define best way perform translocation. The study carried out Brazilian Atlantic rain (called releaser receptor fragments) Salvador, State Bahia, Brazil. A comparison...
The response of plants to increasing atmospheric CO2 concentration depends on several factors such as life history specific species, availability water, nutrients and light, the ecological context that are found. Although experiments with elevated (eCO2) have been done worldwide, none was performed in Amazon forest understory focusing a community growing naturally. central is limited by both light phosphorus. Understanding how ecosystem responds eCO2 important foresee will function future....
As formigas são os principais dispersores invertebrados de sementes encontradas no solo. No entanto, ainda conhecemos pouco sobre a história natural das espécies e como elas poderiam atuar na dispersão sementes. Em busca padrões alométricos entre sementes, que ser extrapolados para outros locais outras espécies, comparamos modelos artificiais com tamanhos diferentes relacionamos algumas medidas tamanho formigas. foram oferecidas em seis transectos dez pontos observação instalados campus da...
<p>Soils of tropical forests generally have low fertility, therefore nutrient cycling has great importance in these ecosystem functions, once soil elements are essential for vegetative tissue and plant metabolic processes. Understanding quantifying the processes that involve acquisition, storage, output plants, their relationship with forest productivity biomass, is to characterize dynamics understand how global environmental changes, such as increase CO2 can affect Therefore,...
