Models reveal the high carbon mitigation potential of tropical forest regeneration.
Tropical secondary forests recover quickly (decades) in tree species richness but slowly (centuries) composition.
Tropical forests disappear rapidly because of deforestation, yet they have the potential to regrow naturally on abandoned lands. We analyze how 12 forest attributes recover during secondary succession and their recovery is interrelated using 77 sites across tropics. are highly resilient low-intensity land use; after 20 years, attain 78% (33 100%) old-growth values. Recovery 90% values fastest for soil (<1 decade) plant functioning (<2.5 decades), intermediate structure species diversity (2.5...
Significance Tropical forests disappear rapidly through deforestation but also have the potential to regrow naturally a process called secondary succession. To advance successional theory, it is essential understand how these and their assembly vary across broad spatial scales. We do so by synthesizing continental-scale patterns in succession using functional trait approach. show that start pathway of varies with climatic water availability. In dry forests, driven drought tolerance traits...
The recovery of soil conditions is crucial for successful ecosystem restoration and, hence, achieving the goals UN Decade on Ecosystem Restoration. Here, we assess how soils resist forest conversion and agricultural land use, recover during subsequent tropical succession abandoned fields. Our overarching question resistance depend local such as climate, type land-use history. For 300 plots in 21 sites across Neotropics, used a chronosequence approach which sampled from two depths old-growth...
The most important condition of ecological restoration is the identification reference ecosystems, which function as a guide for assertive practice with biological integrity and ecosystem structure can be compared. For conservation projects to effective in current scenario biodiversity services decay worldwide, it fundamental understand soil-plant interactions each environment. In this study, we evaluated composition flora 45 plots, equally distributed three preserved areas (reference...
The chromatographic fractionation of the Mauritia flexuosa L. f., Arecaceae, leaves extract, a plant known by name buriti palm tree, resulted in isolation six flavonoids: tricin-7-O-rutinoside, apigenin-6-C-arabinoside, 8-C-glucoside (isoschaftoside), kaempferol-3-O-rutinoside (nicotiflorine), quercetin-3-O-rutinoside (rutin), luteolin-8-C-glucoside (orientin) and luteolin-6-C-glucoside (isoorientin). flavonoids were found out previously reported as constituents Arecaceae family plants, but...
In Cerrado humid areas, veredas are considered as hygrophilous communities, marked by the presence of Mauritia flexuosa palm tree emerging in wetter zones. Changes ecosystems due to drought and changes water table, which represent important areas for biodiversity maintenance Brazilian cerrado, can lead emergence new landscapes ecosystems. Assuming that changed species composition anthropogenic factors, this study, we evaluated flora described current vegetation profile two under different...
Os objetivos deste estudo foram caracterizar e comparar a composição florística de oito fragmentos Mata Seca Calcária Caatinga Arbórea localizados no norte do Estado Minas Gerais. O levantamento das espécies arbóreas foi realizado através visitas periódicas aos para coleta material botânico. Nos encontradas 114 pertencentes 40 famílias botânicas. Dentre as 89 nos Seca, 37 (42%) peculiares essa formação. No entanto, 75 amostradas remanescentes Arbórea, 25 (33%) ocorreram apenas nesses...
Myracrodruon urundeuva Allemão, espécie arbórea conhecida como aroeira, constitui-se em um importante componente das Florestas Estacionais Deciduais do norte de Minas Gerais. Apesar disso, a aroeira vem sofrendo processo exploração intensa, forma predatória, o que causando devastação suas populações naturais. Este trabalho teve objetivo conhecer os padrões fenológicos reprodutivos e vegetativos, bem capacidade germinativa da na Área Preservação COPASA Juramento, MG. Foram feitas observações...
Abstract The high biodiversity of tropical forest streams depends on the strong input organic matter, yet leaf litter decomposition dynamics in these are not well understood. We assessed how seasonal litterfall affects breakdown, density and biomass aquatic invertebrates, microbial sporulation hyphomycetes a South American grassland ‘vereda’ landscape. Although production riparian area was low, breakdown compared with other systems, maximum values coinciding rainy season. Fungal decomposing...
Abstract Aim Successional changes in functional diversity provide insights into community assembly by indicating how species are filtered local communities based on their traits. Here, we assess successional taxonomic and richness, evenness redundancy along gradients of climate, soil pH forest cover. Location Neotropics. Time period Last 0–100 years. Major taxa studied Trees. Methods We used 22 chronosequence studies 676 plots across the Neotropics to analyse Hill's trees, these vary with...
Este estudo teve como objetivo analisar diferenças na estrutura fisionômica, diversidade de espécies e composição guildas da comunidade arbórea setores um fragmento floresta semidecidual que se encontram em diferentes fases regeneração graus exposição à borda. O fragmento, possui 5,8ha área está situado no município Lavras, MG (21°13'40''S, 44°57'50''W), foi dividido quatro submetido a censo das árvores com DAP > 5cm. Os foram comparados quanto densidade, basal, distribuição alturas...
We analyze here how much carbon is being accumulated annually by secondary tropical dry forests (TDFs) and structure, composition, time since abandonment, climate can influence the dynamics of forest accumulation. The study was carried out in Santa Rosa National Park Guanacaste province, Costa Rica Mata Seca State Minas Gerais, Brazil. Total storage accumulation were obtained for both sites from sum aboveground belowground gain plus annual litterfall. Carbon these TDFs varied 2.6 Mg C ha−1...
In this study, we evaluated variation in vegetative and reproductive phenological events of four phylogenetically related plant species subjected to a seasonal environment. To aim, sampled 15 individuals each every fortnight for one year, between January December 2017. assess when given phenophase occurred more intensely the population, Fournier intensity index was used synchrony sample event estimated using activity index. The Rayleigh (Z) test determine whether have distribution....
