“…These results are in line with many other studies which have emphasized the simultaneous existence and role of both mechanisms and have concluded that these hypotheses are not mutually exclusive (e.g. Conti and Díaz 2013;Tahmasebi et al 2017). Lastly, as hypothesized, we showed that the functional groups based on plant life form have an influence on the relationships between plant diversity and soil functions.…”

“…For example, Finke and Snyder (2008) emphasized the importance of diversity in increasing the use of available resources (due to niche complementary) leading to a higher production of biomass and carbon storage. In contrast, Tahmasebi et al (2017) put forward the central role played by the dominant ecosystem species (selection effects) while they found no evidence to support the niche complementary hypothesis. These contrasted studies illustrate that changes in environmental conditions can cause differences in the mechanisms that determine the relationships between biodiversity and ecosystem functioning (Mokany et al 2015).…”

“…The results of the present study show that soil-based functions of ecosystem increase simultaneously with increasing richness and diversity of plant species. Many studies have recorded a positive relationship between increased species richness and ecosystem function including soil carbon sequestration (Cardinale et al 2012;Tahmasebi et al 2017), microbial respiration (Dias et al 2010), and microbial biomass carbon (Rawat et al 2019). A positive relationship was also observed between ecosystem functions and species richness not only in forest ecosystems Sullivan et al 2017;Liu et al 2018) but also in other ecosystems such as grasslands (Li et al 2019) or marine ecosystems (Worm et al 2006;Burkepile and Hay 2008).…”

There is a growing body of knowledge that ecosystem functions, in particular soil-based ecosystem functions, are related to biodiversity. However, how plant species diversity influences soil-based functions along post-agricultural secondary succession is still a largely ignored question in Mediterranean semi-arid conditions. Therefore, we used the plant functional group approach to investigate the relationships between plant species diversity indices and soil-based functions including microbial biomass carbon (MBC), basal respiration (BR) and carbon sequestration (CS) across three different stages of the vegetation succession corresponding to ~ five years after agricultural abandonment, ~ 15 years after abandonment, and oak forests which represent the terminal stage. We also tested if these relationships are supported by the niche complementarity and selection effect hypotheses. The results showed that soil-based functions significantly increased with time since abandonment as BR, MBC and CS increased respectively by 1.7, 1.5 and 2.7 times across the three successional stages. We also found strong correlations between the diversity indices and the soil-based functions BR, MBC and CS which were positive for richness (R 2 values: 0.75, 0.74 and 0.75) and Shannon diversity (R 2 values: 0.61, 0.58 and 0.61) but negative for evenness (R 2 values: 0.38, 0.38 and 0.36 for, respectively). Similarly, richness and Shannon diversity of the different plant functional groups positively correlated with soil-based functions. However, contrasted results were found for evenness which positively correlated with soil-based functions for perennial grass only. We suggested that increasing the diversity of plant species and facilitating dominant species would be needed to improve the soil-based ecosystem functions after abandonment of degraded soils. This study also revealed that the mechanisms behind the relationships between biodiversity and ecosystems functions were influenced by the vegetative forms. Keywords Carbon sequestration. Cropland abandonment. Land use change. Richness. Semiarid forest Highlights  Species diversity and soil-based functions improve along the successional stages after land abandonment  The relationships between plant diversity and soil-based functions are influenced by the plant functional groups..  Niche complementarity plays a more vital role in soil-based ecosystem functions than the selection effect.

“…The soil shows a higher mineralization rate of carbon and nitrogen with the vegetation restoration. Many studies have shown that soil function increases with the increase in plant species richness and diversity, such as increasing soil carbon and nitrogen content [44,45], reducing leaching, and improving soil nutrients [46,47]. In this study, the soil quality index increased gradually with the succession from bare land to forest land, which showed the effect of vegetation on soil development.…”

The bare lands formed after volcanic eruptions provide an excellent opportunity to study the interactions between vegetation succession and soil formation. To explore the changes in soil physicochemical properties in the vegetation succession processes and the relationship between them, soil physicochemical properties of different volcanic ash accumulation on Miyake-jima Island were studied at different vegetation succession stages. The results showed that soil bulk density gradually decreased and that soil porosity, soil water content (SWC), pH, cation exchange capacity (CEC), soil total organic carbon (TOC), and total nitrogen (TN) increased significantly with vegetation succession. The physicochemical properties changes in the soil surface horizon were most obvious, and the deep soil accumulated a large amount of relatively stable soil carbon and nitrogen. The forest land formed a thicker organic matter horizon, accumulating more carbon and nitrogen than grassland, and the soil quality index (SQI) was higher than that of grassland and shrubland. In conclusion, our research indicates the significant change in soil physicochemical properties and the improvement in soil quality in the vegetation succession processes, emphasizing a significant relationship between vegetation succession and soil development in bare land.

“…Plant functional traits are considered good surrogates of ecosystem function (Díaz & Cabido, ; Díaz et al, ; Lavorel & Granier, ; Tahmasebi, Moradi, & Omidipour, ). Ten plant functional traits which present adaptations relevant to nutrient cycling, provision of food to animals, primary production and response to damage were recorded for each plant taxa (Appendix ).…”

Rainfall and herbivory shape savannah herbaceous communities, but these disturbances are being altered globally. To assess potential consequences of such alterations, we evaluated herbivore effects on species and functional diversity during an episodic drought in a sodic savannah using data collected from long-term herbivore exclosures in the Kruger National Park, South Africa. Herbaceous life forms are rarely acknowledged as distinct functional entities. Moreover, the functional ecology of forbs remains elusive. Here, we present disturbances-responses by forbs separately from grasses. We hypothesised that combinations of intense utilisation and drought would be associated with low diversity and high dominance at species and functional levels for both life forms. Contrary to our hypothesis, low forb and grass diversity was associated with long-term herbivore exclusion, which exceeded expected undesirable effects of intense utilisation and drought. Grasses responded less sensitively, suggesting that forbs respond dynamically to changes in herbivore assemblage when these alterations are combined with drought. Consistent with patterns in savannah systems, forbs contributed significantly to species and functional trait diversity.High forb diversity is suggested to enhance resilience of this nutrient-rich ecosystem against declines in its functioning when subjected to drought and alterations in herbivory. RésuméLes précipitations et les herbivores modèlent les communautés herbacées de la savane, mais ces perturbations sont en train d'être modifiées à l'échelle mondiale. Pour évaluer les consequences potentielles de telles altérations, nous avons évalué les effets des herbivores sur la diversité des espèces et des fonctions pendant une sécheresse épisodique dans une savane sodique en utilisant des données collectées sur des enclos à long terme pour herbivores dans le parc national Kruger, en Afrique du Sud. Les formes de vie herbacées sont rarement reconnues comme des entités fonctionnelles distinctes. De plus, l'écologie fonctionnelle des plantes herbacées reste difficile à atteindre. Ici, nous présentons les réactionsperturbations des plantes herbacées séparément des herbes. Nous avons émis l'hypothèse que les combinaisons d'utilisation intense et de sécheresse seraient associées à une faible diversité et à une forte domination au niveau des espèces et des fonctions pour les deux formes de vie.
