Abstract Growth rate varies across plant species and represents an important ecological strategy for competition, resource use and fitness. However, empirical studies often show a low predictability of functional traits to tree growth. We measured stem diameter and height growth rates of 96 juvenile trees (2 to 5 m tall) of eight evergreen and eight deciduous broadleaf tree species over three consecutive years in a subtropical forest in southwestern China. We examined the relationships between tree growth rates and 20 leaf/stem traits that associated with carbon gain, stem hydraulics and nutrient use efficiency, as well as the difference between evergreen and deciduous trees. We found that cross-species variations of stem diameter/height growth rate can be predicted by leaf photosynthetic capacity, leaf mass per area, xylem theoretical specific hydraulic conductivity, wood density and photosynthetic nutrient use efficiencies. Higher leaf carbon assimilation and lower leaf/stem constructing costs facilitate deciduous species to be more resource acquisitive and consequently faster growth within a relatively shorter growing season, whereas evergreen species exhibit a more conservative strategies and thus slower growth. Further, stem growth rates of evergreen species showed were more dependence on leaf carbon gains, whereas stem hydraulic efficiency were more important for deciduous tree growth. Our results suggest that physiological traits (photosynthesis, hydraulics, nutrient use efficiency) can predict tree diameter and height growth of subtropical tree species. The differential resource acquisition and use strategies and their associations with tree growth between evergreen and deciduous trees provide insights in explaining the co-existence of evergreen and deciduous tree species in subtropical forests.

ABSTRACTThe distribution of the nutrients N, P and K in soil and vegetation and their mobility through litterfall and decomposition in mature and successional stands of a subtropical dry forest were studied in Guánica, Puerto Rico. Soils of the Guánica forest have high total amounts of N (9100 kg/ha), P (1820 kg/ha), and K (7460 kg/ha). However, high extractable Ca (>4000 mg/g) and pH (> 7–8) may explain why only 1.3 and 25% of the total P and K, respectively, were extractable. Total ecosystem storage of N, P and K was 10,300, 1900 and 7700 kg/ha, respectively, of which vegetation stored only 10, 2 and 3%, respectively. Litterfall returned 26, 18 and 180% per year of the N, P and K stored in the ground litter compartment. Trees retranslocated about 30 and 65% of the N and P required to satisfy aboveground net primary production and immobilized P in dead roots. Slow leaf decomposition (7.3 yr for 95% decomposition) released K faster than mass, P as fast as mass, and ash and N slower than mass. The use efficiency of P by litterfall was high compared with other tropical forests, while that of N and K was similar to other tropical and temperate forests. Cutting and regrowth of vegetation resulted in differences in the nutrient concentration in litterfall and nutrient use efficiency of successional vegetation.

The Absolute

Seasonal changes in 10 nutrients were investigated in the foliage and current twigs of jack pine (Pinusbanksiana Lamb.) and northern pin oak (Quercusellipsoidalis E.J. Hill) growing on a sandy, nutrient-poor soil in northwestern Wisconsin. Midsummer (July 26) concentrations of all nutrients except Zn were significantly greater in oak foliage than in current needles of pine. Whereas the absolute amounts of N, P, K, Mg, S, B, and Fe in oak foliage peaked in midsummer, generally in late July, the amounts of Ca, Zn, and Mn continued to increase until leaf abscission. The absolute amounts of all 10 nutrients in current needles of pine increased over the growing season. Absolute amounts of nutrients in 2- and 3-year-old needles generally decreased from midsummer to leaf abscission. The two species differ in mechanisms of nutrient-use efficiency. Northern pin oak has a greater requirement for all macronutrients except Mg than jack pine. Although the absolute amounts are greater, proportionally lower amounts of required nutrients are retained in perennial tissues of northern pin oak than in jack pine. A large portion of the nutrient requirement in oak is met by recycling of nutrients contributed by litterfall, throughfall, and fine-root turnover. Northern pin oak resorbed greater amounts of N and K prior to leaf abscission than jack pine. In contrast, jack pine conserves nutrients by investing low amounts of nutrients per unit of leaf or bolewood production and by returning a low proportion of nutrients in litterfall per unit aboveground tissue produced.

To determine the relative importance of soil moisture and soil nutrient availability in determining levels of nutrient use efficiency, seasonal nutrient dynamics and growth rates were determined for individuals of Hamamelis virginiana L., an understory tree, in three forest microsites. The mixed oak site had the lowest levels of soil nutrients and moisture, the mixed mesophytic site the highest nutrient availability, and the valley bottom the highest moisture levels. Foliar nitrogen and phosphorus levels declined over the season in all trees, while calcium levels increased with time. Relative growth rates did not differ significantly among sites, though growth varied inversely with tree mass. Proportional nitrogen resorption was highest in trees at the fertile mesophytic site. Phosphorus and calcium use efficiency were higher at the infertile mixed oak site than the others, and phosphorus resorption was highest in trees from the mixed oak site. Projected nitrogen uptake needs for the next growing season were least at the mixed mesophytic site, while projected phosphorus uptake needs were least at the mixed oak site. Within the ranges of moisture and soil pH – nutrient availability present, growth and nitrogen dynamics seemed most closely correlated to soil moisture, and phosphorus dynamics to phosphorus availability. This differential dependence among elements on moisture levels is suggested to be the underlying reason for differences in the form of the relationship between proportional resorption and soil availability of N and P for a variety of woody species.
