Forests are the largest terrestrial biomass pool, with over half of this stored in highly productive tropical lowland forests. The future evolution forest depends critically on response tree longevity and growth rates to climate. We present an analysis variation rate using tree-ring data 3,343 populations 438 species assess how climate controls across world biomes. Tropical trees grow, average, two times faster compared from temperate boreal biomes live significantly shorter, average (186 ±...
In central Amazonian white-water floodplains (várzea), different forest types become established in relation to the flood-level gradient. The formations are characterized by typical patterns of species composition, and their architecture results light reflectance patterns, which can be detected Landsat TM image data. Ground checking comprised a detailed inventory 4 ha, with Digital Elevation Models (DEM) being generated for all sites. indicate that, at average flood level 3 m, diversity...
We investigated tree water relations in a lower tropical montane rain forest at 1950–1975 m a.s.l. southern Ecuador. During two field campaigns, sap flow measurements (Granier-type) were carried out on 16 trees (14 species) differing size and position within the stand. Stomatal conductance (gs) leaf transpiration (El) measured five canopy 10 understory plants. Atmospheric coupling of stomatal was good (decoupling coefficient Ω = 0.25–0.43), but response gs El to atmospheric environment...
Age and radial growth rate are key data on understanding some aspects of tropical forest dynamics ecology.In species that produce annual tree rings, tree-ring analysis allows the most precise estimate these two parameters.The present study assessed age three Hymenaea inhabiting four six biomes found in Brazil.Out biomes, harbor largest rainforests South America, Amazon Forest west Atlantic east.The Cerrado biome is an open seasonally drier vegetation between them Pantanal a wetland west.The...
The stable isotopes of carbon were analysed in total wood and cellulose from the tree-rings tropical species Cariniana micrantha (Ducke). aim was to examine isotopic relationship between its over last two a half centuries. Although correlation for whole time period is very high (r = 0.96) it remarkable that different sub-periods deviate strongly this close relationship. Consequently, good subset longer record cannot necessarily prove validity record. study indicates changes show sometimes...
The wood of the pau-brasil tree (<em>Paubrasilia echinata</em> Lam., formerly <em>Caesalpinia Lam.) is used worldwide as raw material for construction high-quality bows string instruments. Alternative species are rarely accepted by professional musicians, or bow and violin makers. Historical overexploitation this endemic in Brazilian Atlantic Forest biome (Mata Atlântica), a global biodiversity hotpot including UNESCO World Natural Heritage Sites, illegal trade have caused drastic declines...
Abstract Charcoal is an important urban fuel; however, when production unregulated, it a major cause of land and forest degradation. Production through selective harvesting the preferred large, hardwood tree species leads to degraded residual or woodland composed juvenile trees unused softwood species. This situation can be addressed by ensuring that rate extraction does not exceed mean annual increment. study estimated sustainable for charcoal in Mutomo District, based on field data...
Tropical forests uptake more atmospheric CO2 and transpire water than any other forest in the world are critical components of global carbon hydrological cycles. Both cycles depend to a great extent on balance individual trees. Such adjustments usually evaluated through well-established newly-emerging traits but integrating them for systemic understanding trees' responses climate change can be challenging. We propose using complex correlation networks integrate understand how trees...
