Quercus fabri is a pioneer species of secondary succession in evergreen broadleaved forests in China. In this study, we isolated and developed 12 polymorphic and 2 monomorphic microsatellite loci for Q. fabri using the biotin-streptavidin capture method. We characterized 12 polymorphic loci in 52 individuals from two populations. The number of alleles per locus ranged from 3 to 23. The observed...

To explore the importance of soil microbial community composition on explaining the difference in heterotrophic soil respiration (R(h)) across forests, a field investigation was conducted on Rh and soil physiochemical and microbial properties in four subtropical forests in southern China. We observed that Rh differed significantly among forests, being 2.48 ± 0.23, 2.31 ± 0.21, 1.83 ± 0.08 and 1...

Soil extracellular enzyme activities among aggregate fractions are critical to short-term microbial activity and long–term carbon dynamics in forest ecosystems, but little is known regarding the effects of types on soil different fractions. Three typical subtropical (Broadleaved forest, Moso bamboo Chinese fir forest) were selected, undisturbed samples (0–15 cm) collected. We investigated stabi...

Assessing environmental effects of shelter forests is primarily necessary for realizing their greatest protective benefits. The Three-North Shelter Forest Program (TNSFP), the largest ecological afforestation program in the world, has been operated for three decades in China but so far lacks comprehensive assessment of its environmental impacts. Horqin Sandy Land (HSL) in Northeast China is one...

The aim of this study was to investigate vegetation composition in broadleaved  and conifers plantations in 220 ha of  Loblloly pine (Pinus taeda), alder (Alnus glutinosa( and poplar (Popolus deltoides) hardwood plantations and its comparison with natural forests in Bibiyanlu protected forest park, Astara. A total of 60 sampling plots of 1000 m2 were taken using randomly-systematic method with1...

Assessing forest stand conditions in urban and peri-urban areas is essential to support ecosystem service planning and management, as most of the ecosystem services provided are a consequence of forest stand characteristics. However, collecting data for assessing forest stand conditions is time consuming and labor intensive. A plausible approach for addressing this issue is to establish a relat...
