“…The p i /p a of tropical trees also appears to have remained approximately constant in response to variation in p a from preindustrial times to the present, as inferred from tree-ring D 13 C (Hietz et al, 2005;Nock et al, 2010;Brienen et al, 2011). A similar pattern was inferred for subtropical vegetation from preindustrial times to the present, based on changes in SD and morphology Lammertsma et al, 2011).…”

We investigated responses of growth, leaf gas exchange, carbon-isotope discrimination, and whole-plant water-use efficiency (W P ) to elevated CO 2 concentration ([CO 2 ]) in seedlings of five leguminous and five nonleguminous tropical tree species. Plants were grown at CO 2 partial pressures of 40 and 70 Pa. As a group, legumes did not differ from nonlegumes in growth response to elevated [CO 2 ]. The mean ratio of final plant dry mass at elevated to ambient [CO 2 ] (M E /M A ) was 1.32 and 1.24 for legumes and nonlegumes, respectively. However, there was large variation in M E /M A among legume species (0.92-2.35), whereas nonlegumes varied much less (1.21-1.29). Variation among legume species in M E /M A was closely correlated with their capacity for nodule formation, as expressed by nodule mass ratio, the dry mass of nodules for a given plant dry mass. W P increased markedly in response to elevated [CO 2 ] in all species. The ratio of intercellular to ambient CO 2 partial pressures during photosynthesis remained approximately constant at ambient and elevated [CO 2 ], as did carbon isotope discrimination, suggesting that W P should increase proportionally for a given increase in atmospheric [CO 2 ]. These results suggest that tree legumes with a strong capacity for nodule formation could have a competitive advantage in tropical forests as atmospheric [CO 2 ] rises and that the water-use efficiency of tropical tree species will increase under elevated [CO 2 ].

“…For ten tropical tree species long-term trends in stable isotope levels have now been obtained (Hietz et al 2005;Gebrekirstos et al 2009;Nock et al 2010;Brienen et al 2010b;Gebrekirstos et al 2010). A decrease in d 13 C over time was reported, which led to an increase in intrinsic water use efficiency (iWUE) for six species (Hietz et al 2005;Nock et al 2010;Brienen et al 2010b). Cedrela odorata and Swietenia macrophylla from Brazil showed an increase in C i over time, which led to an increase in iWUE of 34 and 52%, respectively, from 1850 to 1990 (Hietz et al 2005).…”

Over the last decade the field of tropical dendroecology has developed rapidly and major achievements have been made. We reviewed the advances in three main themes within the field. First, long chronologies for tropical tree species were constructed which allowed climate reconstructions, revealed sources of climatic variation and clarified climate-growth relations. Other studies combined tree-ring data and stable isotope ( 13 C and 18 O) measurements to evaluate the response of tropical trees to climatic variation and changes. A second set of studies assessed long-term growth patterns of individual trees throughout their life. These studies enhanced the understanding of growth trajectories to the canopy, quantified autocorrelated tree growth and yielded new estimates of tree ages. Such studies were also used to reconstruct the disturbance history of tropical forests. The last set of studies applied tree-ring data to growth models. Tree-ring data can replace diameter measurements from research plots, provide additional information to construct population models, improve timber yield models and validate model output. Based on our review, we propose two main directions for future research.(1) An evaluation of the causes and consequences of growth variation within and among trees and their relation to environmental variation. Studies evaluating this directly contribute to improved understanding of tropical tree ecology. (2) The simultaneous measurement of widths and stable isotope fractions in tree rings offers the potential to study responses of trees to climatic change. Given the major role of tropical forests in the global carbon cycle, knowing these responses is of high priority.

Climatic hazards, such as severe droughts and floods, affect extensive areas across monsoon Asia and can have profound impacts on the populations of that region. The area surrounding Indonesia, including large portions of the eastern Indian Ocean and Java Sea, plays a key role in the global climate system because of the enormous heat and moisture exchange that occurs between the ocean and atmosphere there. Here, we evaluate the influence of rainfall variability on multiple treering parameters of teak (Tectona grandis) trees growing in a lowland rain forest in Central Java (Indonesia). We assess the potential of, annually resolved, tree-ring width, stable carbon ( 13 C) and oxygen ( 18 O) isotope records to improve our understanding of the Asian monsoon variability.Climate response analysis with regional, monthly rainfall data reveals that all three tree-ring parameters are significantly correlated to rainfall, albeit during different monsoon seasons. Precipitation in the beginning of the rainy season (Sep-Nov) is important for tree-ring width, confirming previous studies. Compared to ring width, the stable isotope records possess a higher degree of common signal, especially during portions of the peak rainy season (
