However, the responses of MDSLs to different climate and site variables still need to be clarified. Thus, this study aimed to assess the potential effects of various climate- and site-related factors on the slopes and intercepts of MDSLs for <em>Larix</em> spp. plantations in northeast China. The parameters of MDSLs were estimated using stochastic frontier regression (SFR) with three different error distribution assumptions, namely half-normal distribution (HN), exponential distribution (ED), and truncated-normal distribution (TN). Spatial distributions of maximum stand density index (<em>SDI<sub>max</sub></em>) were mapped under different climate scenarios (RCP 8.5, RCP 4.5, and RCP2.6). The results revealed that the slopes on MDSLs without covariates were significantly shallower than Reineke's slope (−1.605), ranging from −1.2485 to −1.2026. Of the 22 covariates considered, 13 variables on SFR-HN and SFR-TN and 16 variables on SFR-ED had significant influences on MDSLs. The optimal MDSL model, including mean annual temperature (MAT) and soil pH as covariates using a HN assumption, decreased the Akaike's Information Criterion (AIC) by approximately 7.76%. The results also indicated that increasing MAT significantly reduced the maximum stand density for stands with a natural logarithm of quadratic mean diameter [ln(QMD)] below 2.6, while consistent increases were observed over the entire ln(QMD) range for soil pH. Moreover, the mean <em>SDI<sub>max</sub></em> within the whole region increased significantly from 15.04% under RCP4.5 to 27.78% under RCP8.5. These findings emphasize the significant influences of climate and site conditions on the MDSL, thereby calibrating on traditional density management strategies may contribute significantly on carbon sequestration capacity of forests in the face of climate change.</div></div>","PeriodicalId":51043,"journal":{"name":"Ecological Modelling","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142441642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper provides a comprehensive review of advances and challenges for mechanistically representing lianas in forest ecosystem models and a proposed path towards effectively representing lianas in these models.</div><div>Defining a liana plant functional type is a significant challenge because of the high morphological and physiological diversity amongst liana species, and because of their structural association with trees. Here, we identify critical liana traits that likely should contribute to establishing a liana plant functional type, along with key processes to properly represent lianas in ecosystem models. Subsequently, we discuss a variety of possible liana implementation strategies with their associated strengths, limitations, computational costs and data requirements. A fundamental redesign of the tree-centric demographic vegetation models seems appropriate to accommodate the unique growth and competition strategies of lianas. We illustrate the potential of such models with a single-site case study where we disentangle putative mechanisms of liana increasing abundance. Furthermore, we underscore the critical need for comprehensive liana demographic and functional data (including long-term, physiological, and pantropical observations) for the qualitative implementation and evaluation in the proposed modeling efforts. Currently, there is a scarcity of liana data and the data that do exist have a neotropical bias.

The modeling methodology for habitat suitability is a valuable tool for assessing habitat conditions based on the ecological preferences of indicator species; however, its application to such species in forest soils remains unexplored. Therefore, this study aimed to fill this gap by identifying an optimal procedure for developing a fuzzy model to evaluate the habitat suitability of indicator species based on their abundance classes. Fuzzy models were developed for assessing the habitat suitability of <em>Folsomia quadrioculata</em> and <em>F. octoculata</em> based on data collected from seven mountains using three types of selected variable numbers (3-, 4-, and 5-variable) for two input variable selection methods (statistics-based variable selection, SVS; knowledge-based variable selection, KVS), and their performance was compared. Our results indicate that the SVS-fuzzy model performed better than the KVS-fuzzy model in both the model training and testing phases. As the number of input variables increased, the performance of the KVS-fuzzy model improved; however, it still exhibited lower performance compared to the SVS-fuzzy model. Meanwhile, the optimal SVS-fuzzy model effectively explained the abundance classes of the two collembolan species based on the environmental conditions of their habitats (F1 score &gt; 0.743, Matthews correlation coefficient &gt; 0.520). The findings of this study provide a solid foundation for developing effective models to understand the habitat suitability of soil indicator species.

We used the individual based forest model SORTIE-ND with adult growth forced by four different projected climate change scenarios. To mimic the natural colonization of temperate trees from marginal populations eventually established by long-distance migration, we replaced a patch in the center of the simulated stands with temperate tree species, i.e., red maple, sugar maple or yellow birch. We then performed a sensitivity analysis on the parameters determining the growth, dispersal, and mortality of temperate tree species to determine which of these processes was critical to their expansion. All three temperate tree species were able to colonize the boreal stands with higher performance in younger stands, and greater colonization skills for yellow birch. At the 2100 horizon, the impact of the climate scenarios on the final basal area of temperate tree species was minor. Processes mostly driven by competition and species auto-ecology, including dispersion, mortality, and juvenile growth parameters, were the most important for the colonization capacity.

However, it has also generated severe regional eco-environmental problems, including water shortage, soil erosion, and land desertification. An optimal ecological-network-based regulation of eco-environmentally damaged areas is necessary to balance economic development with rigid eco-environmental constraints in pursuit of sustainable regional development. Using remote-sensing, meteorology, land use, and soil data of energy and chemical industrial areas in the mid-upper reaches of the Yellow River, we quantitatively evaluated the related ecosystem services (ESs) by applying InVEST, CASA, and RWEQ models. Additionally, we constructed ecological conservation networks comprising ecological source areas, resistance surface, corridors, and nodes. The results are as follows. First, from 2000 to 2020, the areas of cultivated and unused land decreased, but those of forest, grassland, water bodies, and construction land increased. Regarding spatial distribution, the proportion of grassland was the highest, followed by unused land, and other types of land accounting for a relatively low proportion. Second, from 2000 to 2020, all ESs and the overall ecosystem improved. However, ESs demonstrated a clear spatial heterogeneity (i.e., better in the southeast than in the northwest). Third, comparing the two ecological networks constructed by minimum cumulative resistance (MCR) and circuit models, the MCR-based ecological network was considered better because of its higher ε, θ, and σ values. Robustness analysis also showed that the MCR-based ecological network was more stable. Finally, ecological source areas of 110,300 km<sup>2</sup> were obtained, accounting for 21.69 % of the study region. Ecological resistance was relatively high in desert areas, which are to the northwest of the study region, and relatively low in the southeast. Fifty-nine ecological corridors (including 31 important ones) and 22 ecological nodes were extracted. The finalized ecological network was diamond-shaped, with the ecological source areas in four directions (i.e., east, south, west, and north) of the study region being closely connected.
