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...
Unprecedenteded rates of deforestation and biomass burning in tropical dry forests are dramatically influencing biogeochemical cycles, resulting resource depletion, declines biodiversity, atmospheric pollution. We quantified the effects varying levels slash—fire severity on nutrient losses redistribution a second—growth forest ("Caatinga") near Serra Talhada, Pernambuco, Brazil. Total aboveground prior to was °74 Mg/ha. Nitrogen phosphorous concentrations were highest litter, leaves attached...
ABSTRACT The phenology of 19 species plants was followed for two years at Serra Talhada, Pernambuco State, Northeastern Brazil. Ten each were monitored biweekly. All had a complete canopy cover from February (well established rainy season) until May‐June (just after rains ceased), and all but few individuals, belonging to six species, leafless in October‐November (peak the dry season). Leaf fall flush, flowering, fruiting almost continuous community throughout both years, they peaked...
A Vegetação Caducifólia Espinhosa (VCE) que recobre a maior parte do semi-árido, vulgarmente chamada caatinga, é bastante diversificada em função de diferenciações climáticas e morfopedológicas. Como pouco se sabe sobre suas características nos limites sua distribuição, como na região fisiográfica Agreste no planalto da Borborema, foi realizado o levantamento florístico fitossociológico uma área município Caruaru, Pernambuco. Foram amostrados todos os indivíduos com diâmetro caule ao nível...
Ethnobotanical studies have contributed significantly in research of plants with therapeutic potential. The aim the present study was to learn about use native medicinal cited by traditional population "cerradão" (savanna woodland) areas Northeast Brazil, providing data on indications species used and their versatility.Semi-structured interviews were conducted basis a standardized questionnaire designed for key informants selected using "snowball" technique. selection potential performed...
Abstract Sugarcane ( Saccharum spp.) production systems commonly include preharvest or postharvest burning to dispose of residue. In northeastern Brazil, no‐burn mulching practices are being introduced as a labor‐intensive but environmentally more friendly alternative. We examined the effect crop residues on sugarcane yield and C, N, P cycles. Carbon, losses during were measured for first ratoon crop. Postharvest burn mulch treatments compared plant grown an Oxic Haplustult soil. During...
Para testar a hipótese de que vegetação do Seridó é aberta e baixo porte, mesmo em local preservado, foi feito o levantamento fitossociológico uma área na Estação Ecológica Seridó, Serra Negra Norte, RN, Brasil. Todas as plantas lenhosas com perímetro caule 1,30 m altura solo > 3 cm, 100 parcelas 10×10 m, foram contadas tiveram alturas, perímetros diâmetros das copas medidos biomassas aéreas estimadas. Foram encontradas 15 espécies, pertencendo gêneros 10 famílias, índice diversidade...
Allometric equations to estimate total aboveground alive biomass (B) or crown projection area (C) of ten caatinga species based on plant height (H) and/or stem diameter at ground level (DGL) breast (DBH) were developed. Thirty plants each species, covering the common range diameters (3 50 cm), measured (C, H, DGL, DBH), cut base, separated into parts, weighted and subsampled determine dry biomass. Wood density (p) largest branches was determined. B, C, H p ranged from 1 500 kg, 0.2 112 m²,...
The sprouting response of the vegetation in three areas that were slashed and burned under different fire severities was determined a 12 year second growth tropical dry forest (caatinga) near Serra Talhada, PE, Brazil. Plots at onset season (July) on 19 September (B), 26 (C) or 4 October (D). Sprouting responses also examined unburned areas. Longer drying periods resulted increasing severity consumption original biomass (; 74 Mg/ha): 72, 87, 93 percent consumption, respectively. Prior to...
