The extent to which pre-Columbian societies altered Amazonian landscapes is hotly debated. We performed a basin-wide analysis of impacts on forests by overlaying known archaeological sites in Amazonia with the distributions and abundances 85 woody species domesticated peoples. Domesticated are five times more likely than nondomesticated be hyperdominant. Across basin, relative abundance richness increase around sites. In southwestern eastern Amazonia, distance strongly influences species....
Abstract Aim Tropical forests store 25% of global carbon and harbour 96% the world's tree species, but it is not clear whether this high biodiversity matters for storage. Few studies have teased apart relative importance forest attributes environmental drivers ecosystem functioning, no such study exists tropics. Location Neotropics. Methods We relate aboveground biomass ( AGB ) to (diversity structure) (annual rainfall soil fertility) using data from 144,000 trees, 2050 plots 59 sites. The...
Abstract. The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these account for more assimilation and storage than any other terrestrial ecosystem. Based on a unique combination pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements 35 litter measurements), their associated canopy photosynthetic capacity (enhanced vegetation index, EVI) climate, we ask how allocation are related to seasonality...
Abstract Aim Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms evolutionarily, morphologically physiologically distinct from other trees, these differences have important consequences for services (e.g., carbon sequestration storage) in terms responses to climate change. We quantified global patterns palm relative abundance help improve understanding forests reduce uncertainty about under Location...
The Brazilian Cerrado biome consists of a highly heterogeneous tropical savanna, and is one the world's biodiversity hotspots. High rates deforestation, however, place it as second-largest source carbon emissions in Brazil. Due to its heterogeneity, biomass stocks vegetation are variable, mapping monitoring these not trivial effort. To address this challenge, we built an aboveground woody (AGWB) model for using 30-m resolution optical satellite imagery (Landsat-5 Landsat-8), 25-m SAR (ALOS...
Abstract The good functioning of aquatic ecosystems is essential for providing diverse ecosystem services that benefit humans. degradation health due to continuous stressors, such as climate change or water pollution, leading an increase in human risks and well-being. Indicators have been developed determine from recreational drinking water. Still, a general application linking has not done. We here reviewed indicators indices applied assess the their links with risk evaluated extent which...
Ecosystem services (ESs) are extremely important, specifically in urban areas. Urban forests, even representing a pivotal role global sustainability, have been converted into different human-modified landscapes. This paper aims to analyze the ES provided by areas of 25 cities Atlantic Forest Brazil. We used i-Tree Canopy v.7.1 classify land use. quantified monetary benefits vegetation and socioeconomic variables (i.e., total population, population density, Human Development Index (HDI),...
Freshwaters are considered among the most endangered ecosystems globally due to multiple stressors, which coincide in time and space. These local stressors typically result from land-use intensification or hydroclimatic alterations, others. Despite recent advances on stressor effects, current knowledge is still limited manipulative approaches minimizing biological abiotic variability. Thus, assessment of effects real-world required. Using an extensive survey 50 stream reaches across North...
Neste trabalho, descreveram-se a composição florística e estrutura do estrato arbóreo de um remanescente Floresta Ombrófila Densa Submontana (Mata Rio Vermelho) na região Centro-Norte fluminense, comparando-a com outras florestas da região. Foram alocadas oito parcelas 5 m x 100 m, todos os indivíduos vivos mortos DAP > cm foram amostrados. Ao todo, registradas 106 espécies pertencentes 77 gêneros 32 famílias. As famílias maior riqueza Leguminosae (13 espécies) Lauraceae (8), as mais...

Seasonal forests cover about 15% of the Brazilian Savannah and are among most degraded fragmented vegetation types in this biome. This study aimed to provide an overview current knowledge on these disseminate information that can contribute amplification deepening previous studies. It shows studies have already explained a large amount questions raised by earlier researchers, but some important aspects still remains incomplete. The anthropogenic activities reduction remaining areas, as well...
The leaf and soil nutrient status of plants has been used to infer structural functional aspects at the ecosystem level. Such data are available for tropical savanna systems growing on poor acidic soils; however, information species eutrophic basic soils is lacking. Deciduous forest one most endangered types forest, despite high level attention aimed it, little known about nutritional composition its leaves. Here, we provided content ratios relationships deciduous tree a limestone outcrop in...
O presente trabalho teve por objetivo avaliar a composição florística arbórea de um trecho Floresta Atlântica submontana na região Imbaú, Silva Jardim, RJ. Esta formava contínuo florestal que foi fragmentado há mais 50 anos práticas agropecuárias. Cinco fragmentos foram selecionados e em cada deles alocadas quatro parcelas 100×5 m. Todas as árvores vivas com DAP > 5 cm amostradas identificadas. No hectare amostrado encontradas 161 espécies distribuídas 39 famílias. A similaridade entre os...
O objetivo deste trabalho foi avaliar a estrutura diamétrica arbórea de um remanescente Floresta Atlântica Submontana no Município Silva Jardim, RJ. Foram utilizadas 20 parcelas 100 x 5 m, em que todas as árvores com DAP > cm foram amostradas. A analisada toda comunidade e nas principais populações (determinadas segundo o VI), partir histogramas intervalos classes definidos pela fórmula Spiegel. análise também considerou os grupos sucessionais das espécies (pioneiras: PI; secundárias...
O objetivo deste estudo foi analisar as mudanças florísticas e estruturais da comunidade arbórea de uma floresta sobre afloramentos calcários no município Iaciara (14º03'53"S; 46º29'15"O), nordeste Goiás, Brasil Central, após intervalo seis anos (2000-2006). Considerando limitações bióticas impostas pela forte estacionalidade climática condições edáficas estressantes (solos rasos rochosos), partiu-se hipótese que a apresentaria dinâmica acelerada, mas não implicaria em pronunciadas. As foram...
Abstract Recent insights show that tropical forests are shifting in species composition, possibly due to changing environmental conditions. However, we still poorly understand the forest response different change drivers, which limits our ability predict future of forests. Although some studies have evaluated drought effects on tree communities, know little about influence increased water availability. Here, how an increase availability caused by artificial reservoir affected temporal...
Understanding the drivers of aboveground biomass (AGB) variation in present-day tropical forests can contribute to management strategies that help mitigate against CO2-driven climate change and provide other services related high AGB. Higher tree diversity lead higher woody productivity carbon storage, but how interacts with land-use history is less certain. We assessed AGB across different histories surrounding landscapes southeastern Brazil relates per se, while controlling for important...
Plant communities store carbon in their biomass, contributing to the reduction of greenhouse gases atmosphere. Many studies about aboveground biomass (AGB) have been conducted Brazilian Atlantic Forest, but non-forest ecosystems (NFE) remain neglected. This is case cloud savannas that occur at high altitudes (>800 m) Mantiqueira Mountain Range, Southeastern Brazil. To evaluate wood structure and live AGB variation this phytophysiognomy, we carried out an inventory woody dead stems 1-ha...
