“…The model predictions generally integrate previous knowledge from the literature, indicating that: 1) in water-limited conditions, water availability has greater effects on NPP than N mass (Macfarlane et al 2004, Klein et al 2005), leading to a negative correlation between NPP and d 13 C (Condon et al 1987, Roux et al 1996; and 2) when water is not limiting, NPP increases with increasing N mass (Field and Mooney 1986, Wright et al 1988, Sun et al 1996, Livingston et al 1998). Equation 5 further suggests a threshold of water limitation of E/E m B0.85.…”

“…Although the d 13 C of tree-ring and leaf materials has been considered as a reasonable indicator of integrated leaf gasexchange properties (Macfarlane et al 2004, Klein et al 2005, there are very few data to indicate the relationship between foliar d 13 C and NPP at larger geographical scales. This study is a step forward in attempts to quantitatively describe the relationships among community characteristics, climatic factors and leaf traits.…”

Warming climate could affect leaf-level carbon isotope composition (d 13 C) through variations in photosynthetic gas exchange. However, it is still unclear to what extent variations in foliar d 13 C can be used to detect changes in net primary productivity (NPP) because leaf physiology is only one of many determinants of stand productivity. We aim to examine how well site-mean foliar d 13 C and stand NPP co-vary across large resource gradients using data obtained from the Tibetan Alpine Vegetation Transects (1900Á4900 m, TAVT). The TAVT data indicated a robust negative correlation between foliar d 13 C and NPP across ecosystems (NPP 0(2.7224d 13 C-67.738, r 2 00.60, p B0.001). The mean foliar d 13 C decreased with increasing annual precipitation and its covariation with mean temperature and soil organic carbon and nitrogen contents. The results were further confirmed by global literature data. Pooled d 13 C data from global literature and this study explained 60% of variations in annual NPP both from TAVT-measures and MODIS-estimates across 67 sites. Our results appear to support a conceptual model relating foliar d 13 C and nitrogen concentration (N mass ) to NPP, suggesting that: 1) there is a general (negative) relationship between d 13 C and NPP across different water availability conditions; 2) in water-limited conditions, water availability has greater effects on NPP than N mass ; 3) when water is not limiting, NPP increases with increasing N mass .

“…Gingko biloba trees, in Japan, also had higher D at the wettest site than the trees growing at the more arid site (Sun et al 2003). In SW Australia, and across a gradient of rainfall of 600-1,400 mm year -1 , Eucalyptus globulus leaf D ranged from 17 to 21%, and was strongly, positively correlated with the ratio of mean annual rainfall to potential evaporation (Macfarlane et al 2004). For the Mediterranean species Q. ilex, Damesin et al (1997) reported that the site with the lowest rainfall had the smaller mean value of D, whereas the greater mean value of foliar D was found at the most mesic site.…”

The aim of our study was to assess the intraspecific variation of a range of leaf attributes and carbon isotope discrimination (D), in Quercus suber, along an 800 mm rainfall gradient in Portugal. We measured specific leaf area (SLA), leaf thickness (LT) and density, and used leaf carbon isotope content as an integrated record of water use efficiency. The values of SLA of Q. suber were strongly, positively correlated with rainfall, decreasing as rainfall decreased. This reduction was mainly driven by LT, which was tightly correlated with SLA (R = -0.80, P \ 0.001), and steadily increased with declining rainfall. The significant increase in carbon isotope discrimination towards the wetter end of the gradient, with a difference of 4.2% in D between the two extremes, suggests a strong adjustment of leaf gas exchange to water availability. Leaf changes associated with precipitation in Q. suber thus seem to influence water economy, since reduction of SLA with the increase of LT with aridity improves water use efficiency. These data suggest that this evergreen tree species relies on its foliage plasticity and physiology to overcome water shortage.

“…intended for bioenergy have been established mostly in Australia, New Zealand, China, South America, the Mediterranean, and Africa (Niemistö, 1995;Sochacki et al, 2007). Species of this genus are characterized by rapid growth and high wood production, making them the primary choice for biomass production (Macfarlane et al, 2004;Parsons et al, 2004;Forrest and Moore, 2008). Numerous studies report the biomass yield of these species as shortrotation crops established at various stockings (Barton and Montagu, 2006;Sochacki et al, 2007;Forrest and Moore, 2008).…”

-Chile has strong interest in biomass production for the purpose of generating bioenergy to accomplish environmental standards for clean energy production. However, no yield or productivity information is available about forest crop plantations established at high-initial planting densities dedicated to energy production. The objective of the present study was to provide long-term results of short-rotation forest crops research trials, investigating first cutting cycle most promising species biomass production. Plantations of Acacia melanoxylon, Eucalyptus camaldulensis, Eucalyptus globulus, and Eucalyptus nitens were established at initial stockings of 5,000; 7,500 and 10,000 trees ha -1 on marginal sites with important nutritional and hydric limitations in the Biobío Region, Chile. After 48 months, E. camaldulensis reached the highest biomass yield at initial stocking of 7,500 trees ha -1 (22.5 Mg ha -1 ) on dry land granitic soils, and E. nitens reached 35.2 Mg ha -1 on sandy soils. Initial stockings and biomass yields were directly related, but strongly conditioned by mortality, where greater initial stocking concurred with greater mortality after 4 years. The collar diameter and total height growth was lower at higher stockings.Keywords: Bioenergy; Growth and biomass yield; Eucalyptus spp. PRIMEIRO CICLO DE CORTE DE CRESCIMENTO BIOMASSA ACIMA DO SOLO E PRODUTIVIDADE DE ENSAIOS DE DENDROENERGIA DE Acacia E EucalyptusRESUMO -O Chile tem um forte interesse na produção de biomassa com o objetivo de gerar bioenergia para cumprir padrões ambientais para a produção de energia limpa. No entanto, não há informações de produtividade ou produtividade disponíveis sobre plantações de culturas florestais estabelecidas em densidades de plantio elevadas, dedicadas à produção de energia. O objetivo do presente estudo foi fornecer resultados a longo prazo de estudos de pesquisa de culturas florestais de rotação curta, investigando o primeiro ciclo de corte, a produção de biomassa de espécies mais promissoras. As plantações de Acacia melanoxylon, Eucalyptus camaldulensis, Eucalyptus globulus e Eucalyptus nitens foram estabelecidas em meias iniciais de 5.000; 7.500 e 10.000 árvores ha -1 em locais marginais com importantes limitações nutricionais e hídricas na Região Biobío, no Chile. Após 48 meses, E. camaldulensis atingiu o maior rendimento de biomassa na base inicial de 7.500 árvores ha -1 (22,5 Mg ha -1 ) em solos graníticos de terra seca e E. nitens atingiu 35,2 Mg ha -1 em solos arenosos. As meias iniciais e os rendimentos de biomassa foram diretamente relacionados, mas fortemente condicionados pela mortalidade, onde maior estocagem inicial concordou com maior mortalidade após 4 anos. O diâmetro do colar eo crescimento da altura total foram menores nas meias mais altas Palavras-Chave: Bioenergia; Crescimento e produção de biomassa, Eucalyptus spp. 2Revista Árvore. 2017;41(6):e410608 ACUNA E et al.
