This study focuses on the influence of the 2008 ice storm in China and subsequent forest rehabilitation dynamics up until 2011. All seven plots studied exhibited significant damage, with the total number of damaged trees varying between 63 and 92%. In addition, most trees suffered stem bending in 2008 and the extent of damage varied with tree diameter at breast high (DBH). Relationships between loss of biomass as dead trees and stand characteristics were analyzed by multiple stepwise regression. The results showed that the decrease in biomass (Y) could be related to altitude (X1), slope (X2), and aboveground biomass (AGB) in 2008 (X5) according to the following formula:Y=−0.02456X1+0.2815X5−1.480X2+51.23. After 2 to 3 years, tree numbers had declined in all seven plots. The mean increase in AGB (4.9 t ha−1) for six of the plots was less than the biomass loss as dead trees (9.4 t ha−1) over the 3 year periods. This corresponds to a release of CO2to the atmosphere for each plot. Therefore, the forests of Lechang in the Nanling Montains have probably acted as a carbon source to the atmosphere for a short period after the 2008 ice storm.

Mesquite trees are the preferred dendroenergy sources in arid and semi-arid forests. In spite of their relative importance, regional aboveground biomass (AGB) equations for mesquite trees are scarce in the scientific literature. For that reason, the aims of this study were to: (a) harvest trees and develop regional biomass equations; (b) contrast measured data with equations developed previously; and (c) test the applicability of the fitted equation for mesquite trees in the arid and semi-arid forests of the Americas. We harvested 206 new mesquite trees from arid and semi-arid forests in northern Mexico (Coahuila, Nuevo Leon, and Tamaulipas) in addition to using two other previously compiled data sets from Mexico (N = 304) to develop a regional equation. To test the validity of this equation, for biomass equations reported for the rest of the country, as well as for North and South American mesquite trees, we contrasted AGB measurements with predictions of fitted equations. Statistical analysis revealed the need for a single, regional, semi-empirical equation as together the three data sets represented the variability of the aboveground biomass of mesquite trees across northern Mexico, as well as mesquite trees in America’s arid and semiarid regions. Due to the large quantity of mesquite trees harvested for sampling and their variability, the regional biomass equation developed encompasses all other North and South American equations, and is representative of mesquite trees throughout the arid and semi-arid forests of the Americas.

<p>Spatial heterogeneity has been widely used in the study of succession in abandoned croplands worldwide, and it is often accompanied by time heterogeneity. However, the effect of temporal heterogeneity on succession dynamics over decades is not well understood. Here, we used croplands with same history in northwest China that were abandoned in 1998, 1999, and 2000 and continuously monitored vegetation characteristics for ten years. Croplands were left undisturbed throughout the study. Non-metric multidimensional scaling was used to interpret changes in the plant community, and taxonomic and functional diversity measures were compared in three treatment over time. Our results show that the directions of succession in all three croplands were similar, from single superior community (<em>Salsolacollina</em> Pall.) with higher aboveground biomass to multi-superior community (<em>Artemisia capillaris</em> Thunb., <em>Stipa bungeana</em> Trin., <em>Lespedeza davurica</em> (Laxm.) Schindl, Heteropappus altaicus (Willd.) Novopokr) with lower aboveground biomass. Taxonomic and functional diversity increased rapidly in the first 4–6 years, followed by a slow increase, decrease or stabilization. Temporal heterogeneity had no effect on species richness after the 7th year, on the Shannon-Wiener index, species evenness, modified functional attribute diversity, or functional divergence after the 8th year, or functional evenness after 5th year. We conclude that temporal heterogeneity can affect the process of secondary succession but has no effect on the direction of community succession. Our findings provide evidence for using temporal heterogeneity to study succession in abandoned croplands in semi-arid areas. </p>
