Abstract
Oak forests accompanied by Cistus species are a common landscape in the Mediterranean basin. It is argued that Cistus dominated fields serve as recruitment areas for Quercus seedlings, as they help in the transmission of the fungal community through vegetative succession in these ecosystems. To test these assumptions, we analyzed the fungal community in terms of its richness and composition, taking into account the effects of host (Oaks vs. Cistus) and forest structure, mainly based on age. Edaphic variables related to the different structures were also analyzed to examine how they evolve through succession and relate to shifts in the fungal community. No differences in fungal richness were observed between old Cistus stands and younger Quercus, while a brief increase in ECM richness was observed. Community composition also showed a greater overlap between old Cistus and young Quercus stands. We suggest that the most important step in fungal transfer from one host to another is the shift from the oldest Cistus fields to the youngest Quercus stands, with the genera Amanita, Cortinarius, Lactarius, Inocybe, Russula, and Tomentella probably playing a major role. In summary, our work has also revealed the network of fungal community structure in the succession of Cistus to Oak stands, it would suggest that the fungi share niches and significantly enhance the ecological setting of the transition from Cistus to Oak stands.

Abstract
Soil function refers to all the roles and services that the soil performs, and can be assessed by measuring physical, chemical and biological properties. In any case, studies on the state of fertility and biological activities are now emphasized as indicators of soil functions. Degradation of rangelands and their conversion to agricultural land is one of the most common land use changes in different parts of the world, with significant impacts on soil functions. Not much is known about the effects of land use change (especially rangeland to orchards of different ages) on soil function indicators in semi-arid areas. In the current study, the following five types of land covers were considered in a semi-arid region of northern Iran: (1) enclosured rangeland, (2) 10-year-old apple orchard, (3) 25-year-old apple orchard, (4) 10-year-old walnut orchard, and (5) 25-year-old walnut orchard. Results showed that the apple orchards (25-year-old) had a more fertile soil and a higher biological activity than the other land uses studied. Based on heat plots of soil properties under different land uses, the apple orchards (25-year-old) formed hot spots of soil functional indicators in the study area, followed by the walnut orchard (25-year-old) > enclosured rangeland > apple orchard (10-year-old) > walnut orchard (10-year-old). Although the conversion of natural lands (i.e., rangelands) to anthropogenic ones (i.e., orchards) is generally associated with negative feedbacks, tree species can be used (by creating forested rangeland or a combination of rangeland-agriculture) in areas with low soil function to improve soil conditions (in the long term).

Kooch Y, Amani M, Abedi M. Vegetation degradation threatens soil health in a mountainous semi-arid region. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 830:154827. [PMID: 35341847 DOI: 10.1016/j.scitotenv.2022.154827] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 03/10/2022] [Accepted: 03/21/2022] [Indexed: 06/14/2023]
Abstract
Soil biological properties are good indicators for the evaluation of soil quality, introduced as key indicators in soil health, which is in line with the nutrient cycles in terrestrial ecosystems. To the best of the authors' knowledge, responses of belowground biota to habitat degradation have received little attention. The present study aimed to study the effect of different intensities of vegetation degradation [heavy (0-10% coverage), moderate (30-40% coverage) and light (60-70% coverage)] and non-degraded sites (as control; 90-100% coverage) in lands covered by Crataegus and Berberis shrubs on soil fauna, microbiota and microbial activities in the north of Iran. From each of these sites, 45 soil (30 × 30 cm area) samples were taken from 0 to 10 cm, 10-20 cm and 20-30 cm depths and 180 samples were transferred to the laboratory. According to principal component analysis, the studied habitats can be distinguished based on soil health and functional characteristics. In this regard, due to the more fertile soil in ecosystems without degradation, highest soil biological activities belonged to these areas. Following the increase in the intensity of degradation, the population of soil organisms and microbial activities are suppressed due to reduction of organic matter inputs, unsuitable soil microclimate, increase in soil erosion and finally depletion of soil nutrients. The results of this study indicate the dependence of soil quality on aboveground vegetation cover, especially in the topsoil, so the vegetation degradation can cause severe damages to soil health in semi-arid regions.
