Background The Minqin Oasis, which is located in Wuwei City, Gansu Province, China, faces a very serious land desertification problem, with about 94.5% of its total area desertified. Accordingly, it crucial to implement ecological restoration policies such as cropland abandonment this region. In abandoned croplands, abiotic factors soil properties may become more important than biotic driving vegetation succession. However, the connections between and succession remain unclear. To fill knowledge gap, study investigated these explore major that affected succession, meaningful designing management measures restore degraded ecosystems. Methods This seven 1–29-year-old croplands using “space for time” method Oasis. Vegetation was classified into different stages canonical correlation analysis (CCA) two-way indicator species (Twinspan). link analyzed CCA. primary shaping community patterns were chosen by “Forward selection” responses dominant generalized additive models (GAMs). Results Dominant turnover occurred obviously after abandonment. can be three ( i.e ., early, intermediate, late successional stages) markedly composition diversity. main drivers among salinity saturated water content they had led early stages. During development became simpler, diversity decreased significantly, type regressive Therefore, should adopted manage degraded, croplands.

Significance Tropical forests disappear rapidly through deforestation but also have the potential to regrow naturally a process called secondary succession. To advance successional theory, it is essential understand how these and their assembly vary across broad spatial scales. We do so by synthesizing continental-scale patterns in succession using functional trait approach. show that start pathway of varies with climatic water availability. In dry forests, driven drought tolerance traits wet shade traits. Based on principles, we propose an ecologically sound strategy improve active forest restoration.

Abstract Aim Successional changes in functional diversity provide insights into community assembly by indicating how species are filtered local communities based on their traits. Here, we assess successional taxonomic and richness, evenness redundancy along gradients of climate, soil pH forest cover. Location Neotropics. Time period Last 0–100 years. Major taxa studied Trees. Methods We used 22 chronosequence studies 676 plots across the Neotropics to analyse Hill's trees, these vary with continental‐scale precipitation, surrounding Results Taxonomic richness increased, while decreased over time. Functional changed strongly when not accounting for but more weakly after statistically that largely driven richness. Nevertheless, increases correcting may indicate environmental heterogeneity limiting similarity increase during succession. The taxonomically‐independent decreases stronger filtering competition select dominant similar trait values, many rare traits added community. Such also lead increased redundancy. varied resource availability were harsh, resource‐poor environments, weak benign, productive environments. Hence, facilitation important, whereas weaker abiotic allows high initial changes. Main conclusion found succession, mainly caused increasing number due arrival new changing (a)biotic filters.

The spectrum of species diversity (SDi) can be broken down into αSDi (taxocene level), βSDi (community and γSDi (metacommunity level). Species richness (S) Shannon's index (H) are well-known SDi measures. use S as a surrogate for often neglects evenness (J). Additionally, there is wide variety indicators SDi. However, no reliable theoretical criteria selecting the most appropriate despite undeniable empirical usefulness this parameter. This situation probably due to analytical gap still existing between trophodynamics. article contributes closing that by analyzing why single inconsistent from trophodynamic point view, so an combining J, such H or HB (Brillouin's index), choices in context new framework (organic biophysics ecosystems, OBEC) based on classical links ecosystem ecology thermodynamics.

Evaluating plant functional traits helps to understand how plants respond changing environmental conditions and resource availability associated with disturbance events. Livestock production is one of the primary drivers tropical forest loss degradation. alter within by grazing, trampling nutrient inputs, which in turn can influence species composition species. Understanding livestock along a successional gradient poorly understood. Here, we studied effect cattle grazing fallow age on soil nutrients secondary old-growth dry forests. We analyzed most important communities both present excluded plots. Our results showed effects traits, explaining more variation than grazing. In early succession, were water conservation (thicker leaves, lower specific leaf area), later they linked sunlight (larger height, higher area). The presence large fruits seeds advanced sites suggests high availability, may help successfully reproduce. Moreover, under some are herbivory defense (high foliar weight thick leaves). Even though N C increased as succession advanced, had NH4 NO3 concentrations result fecal deposition. Plant responded study that exclusion, management biodiversity strategy, contributes positively nutrition. Thus, exclusion facilitate recovery allows establishing suitable attributes for overcoming filters abandoned fields.
