Tropical rainforest changed in term of structure, composition and population, resulting from logging. One of target trees during logging is Pometia. Our goals of this research were to answer that (1) How were survival, growth, fecundity and population growth rate (λ) of Pometia within remnant stands?; (2) what were driving factors to explain population dynamics of Pometia within logged forest?. Data were derived from three hectares-permanent sample plot (PSP) in logged forest of PT Tunas Timber Lestari. Integral Projection Models (IPMs) were applied to analyze population dynamics. The study showed dynamically that probability of the individuals of Pometia survived in this area did not significantly differ among their size, while stands showed the significant difference between small and large individuals. The growth of both individuals of Pometia and stands varied significantly in different size. The probability of fecundity both Pometia and stands were significantly different among size. The population of Pometia has been increasing for about a decade as the population of all stands was growing as well. Moreover, the regular documentation of species composition and structure before and after logging is necessary as a control of biodiversity. Therefore, a proper protocol to monitor the biodiversity should be designed by government and disseminated it to logging companies.

“…Additionally, tree recruitment and mortality rates across tropical forests have been associated to changing climatic factors (Lewis, Lloyd, Sitch, Mitchard, & Laurance, ; Vilanova et al., ). Forest dynamics are influenced by raising CO 2 levels, local soil fertility (Phillips et al., ), biotic interactions (Ma et al., ), temperature and water availability (Vilanova et al., ). Consequently, many local and regional factors might influence the productivity and carbon dynamics of forests, by driving the mechanisms underlying demographic and biomass changes of trees.…”

“…Little is known about the patterns of biomass change in subtropical remnants of old-growth forests (Ali & Yan, 2017b;Lin, Lai, Muller-Landau, Mi, & Ma, 2012), or about the drivers of tree demographic rates (Ma et al, 2016). Subtropical Atlantic forests have different climatic filters than tropical forests, as evidenced by the fact that floristic variation is related to minimum temperature ranges (Oliveira-Filho, Budke, Jarenkow, Eisenlohr, & Neves, 2015;dos Santos, Saraiva, Müller, & Overbeck, 2015), which might impact forest dynamics.…”

Question How do biotic forest conditions, in terms of plant functional traits and tree basal area, and soil variables influence old‐growth forest dynamics? Location A subtropical old‐growth forest in Southern Brazil. Methods Forest inventories were conducted in 1999 and 2017, in 24 permanent plots of 500 m2. All trees with a circumference at breast height of ≥ 30 cm were measured, identified to the species level, and tagged. We fitted linear models to evaluate the effect of the biotic variables of initial forest communities (tree basal area, trait community‐weighted mean [CWM] and both species and functional diversity metrics) and of soil variables on forest dynamics. These models included biomass dynamics (annual rate of biomass increment and mortality) and demographic rates (recruitment and mortality rates). Furthermore, linear models were used to evaluate the effect of tree survival, recruitment and mortality and biomass increment on the net biomass change. Results We observed a positive effect of species diversity and a negative effect of CWM leaf phosphorus content on the biomass increment. Biomass loss was positively related to basal area and negatively related to the CWM of leaf nitrogen content. Overall, net biomass change was negatively influenced by biomass loss due to mortality. Recruitment rates were negatively affected by soil potassium content and were positively affected by soil pH and functional evenness of the community. Mortality rates were positively predicted by soil clay content and negatively predicted by species diversity. Conclusions Community functional traits, basal area and soil variables predicted growth, mortality and recruitment dynamics of this subtropical old‐growth forest. This work provides important information about the biomass and demographic dynamics of subtropical forests, showing that initial community characteristics influence the gain and loss of biomass and individuals over a period of almost two decades.

Plant sexual systems appear to play an important role in community assembly: Dioecious species are found to tend to have a higher propensity to colonize communities in early successional stages. Here, we test two demographic hypotheses to explain this pattern in temperate forests. First, we test demographic differences between hermaphrodite and dioecious species in stressful younger successional stages: Previous theory predicts that hermaphrodite seed production is more harmed in stressful environments than that of dioecious populations leading to an advantage for females of dioecious species. Second, in primary forest, we hypothesized that dioecious species would show demographic advantage over monomorphic ones. We used data from two temperate forest plots in Northeast China surveyed over 10 years to compare the rates of growth and mortality of tree species with contrasting breeding systems in both secondary and primary forests. We assessed the effect of breeding system on the growth‐mortality trade‐off, while controlling for other traits usually considered as correlates of growth and mortality rates. We show that in the secondary forest, dioecious species showed weak advantage in demographic rates compared with monomorphic species; dioecious species showed considerably both lower relative growth and mortality rates compared to the hermaphrodites in the primary forest over 10 years, consistent with a priori predictions. Hermaphrodites showed strong growth‐mortality trade‐offs across forest stages, even when possibly confounding factors had been accounted for. These results suggest that sexual system influences community succession and assembly by acting on the rates of growth and mortality, and the trade‐off between them. As vegetation develops, the demographic differences between breeding systems are much larger. Our results demonstrate the association between breeding system, succession, and community assembly and that this relationship is succession‐stage dependent. Our findings support the suggestion that the demographic advantage of dioecious species facilitates the coexistence of sexual systems in primary forest.
