“…P and K were analysed with the Mehlich 1 extraction method; Ca2+, Mg2+, Al3+ with 1 mol L-1 KCl extraction; SOC following the Walkley-Black method. Another subset of each composite sample was used for the assessment of easily extractable glomalin (EEG) and total glomalin (TG), extracted from soil (2 g) as described by Wright and Upadhyaya (1998) and detailed in Gomes et al (2021). The data with soil properties per each plot in different habitat types are provided in Supporting Information S1.…”

“…The vegetation comprises a mosaic of physiognomies growing on either quartzitic or ferruginous substrates, which have very different physical and chemical edaphic characteristics (Conceição et al., 2016; Fernandes, 2016; Giulietti et al., 1997). Compared to quartzitic substrates, ferruginous substrates have overall higher nutrient contents and glomalin‐related soil protein, which is produced by arbuscular mycorrhizal fungi (AMF) and is an important agent not only for preserving and accumulating soil organic carbon but also as a stabilizing soil against erosion (e.g., Abrahão et al., 2019; Gomes et al., 2021). Hence, these different substrates are expected to sustain plant species with contrasting resource acquisition strategies (e.g., AMF‐association versus nonmycorrhizal strategies such as sand‐binding roots and vellozioid roots).…”

A functional approach to understand natural plant communities helps elucidate the dynamics of environmental filters and community assembly. Species classification into functional groups allows the translation of ecological complexity into simplified and applicable knowledge. Here, we developed a plant functional type (PFT) system to investigate whether functional structure (PFT composition and abundance) of plant communities varies between substrate types and plant physiognomies in an old climatically buffered infertile landscape (OCBIL), namely Brazilian campo rupestre. We sampled the herbaceous and shrubby vegetation and collected soil variables in four different plant physiognomies growing in quartzitic and ferruginous substrates. We classified the sampled species according to life‐history traits related to species persistence, reproduction, and biological interactions. Functional dissimilarity among plant physiognomies and the two substrate types and the role of soil factors affecting the dissimilarities were assessed. Pollination and seed dispersal syndromes, mycorrhizal association, and reproductive phenology were the main traits defining the PFTs. We found distinct functional structure between plant communities of different substrates and physiognomies, with a marked influence of chemical and physical soil factors. Also, we defined main PFTs profiles for each physiognomy, identifying core PFTs with basic combinations of traits, common to all or almost all physiognomies. The functional perspective proposed by this study provides applicable knowledge to the restoration and conservation of campo rupestre ecosystem, reinforcing the importance of habitat heterogeneity for maintaining its functioning.

“…The campo rupestre forms a complex landscape composed of a variety of habitats such as quartzite and ferruginous outcrops interconnected by stony, gravel, sandy, acidy, nutrient-poor, and low water retention soils (Conceição & Pirani, 2005;de Carvalho et al, 2014;Fernandes, 2016;Schaefer et al, 2016a,b;Silveira et al, 2016). This edaphic diversity is one of the main local modulators of the coexistence of plant species, often endemic and rare (Giulietti et al, 1997;Jacobi et al, 2007;Messias et al, 2013;Fernandes, 2016;Gomes et al, 2021). Despite its restricted area (ca.…”

The increase in rates of habitat loss requires an understanding of how biodiversity is distributed. Campo rupestre is an old, climatically buffered, and infertile landscape located in Brazil. Considered a biodiversity hotspot, the campo rupestre is mainly threatened by mining activity that requires a large operating area. Campo rupestre is known for its restricted distribution area and high abiotic heterogeneity, which modulates species coexistence and richness. To recognise the association between habitat type and plant communities, we propose to describe the floristic composition of herbaceous and shrub components in four habitats of the campo rupestre comprising quartzite and ferruginous substrate. We classified habitat types by the main surface soil features. In each habitat, we sampled ten 100-m2 plots to access information on the shrub and ten 1-m2 plots for the herbaceous component. Altogether we sampled 153 species, belonging to 38 families. The cluster analysis ordered by Sorensen metric indicates a clear distinction of species composition in the shrub component in the four habitats. However, the floristic composition of the herbaceous component was similar between the four habitats but showed a distinction when contrasting with the substrate type. Our results highlight the local taxonomic distinction between habitat types and substrates, indicating that the ecological distinction among substrate types of the campo rupestre cannot be overlooked in conservation and restoration actions.

“…Due to the vegetation loss and changes in edaphic parameters and watercourses after the collapse of the Fundão dam, the restoration of the impacted sites became urgent (Whitham et al 2006, Omachi et al 2018). Otherwise, proper restoration of this vanishing ecosystem requires species that provide structural and functional sustainability to the rest of the biotic community (Whitham et al 2006, De Deyn et al 2008, Hughes et al 2008, Gomes et al 2021), especially those that influence the land–water interface. Species, called basal constitute the foundation of ecosystems, as they create the habitats occupied by other species and/or contribute an important fraction of energy to the food web (Jones et al 1994, Ellison et al 2005, 2010, Davidson and Jeppesen 2013).…”

“…Due to the influence that basal species exert on other organisms, the phenotypic variability of these plants in response to extrinsic factors – biotic or abiotic – and intrinsic genetic factors, will determine the spatio‐temporal heterogeneity, biodiversity and environmental ecosystem services (Whitham et al 2006). Thus, the conservation of these natural systems and even the restoration environment depend on the persistence and success (eco‐efficiency) of these species in the environment (Fernandes et al 2016, Kollmann et al 2016, Gomes et al 2021, Pisani et al 2021).…”

Studies on the composition, richness and diversity of plant species in tropical communities are essential for understanding relevant ecological processes and for developing appropriate conservation policies. Considering that areas subject to direct impacts due to dam breach may in the long‐term present changes in species composition and in soil parameters, we evaluated the composition of the flora, described the current vegetation profile, and evaluated whether differences in species composition was influenced by soil variables of three areas along the Gualaxo River, in Minas Gerais State, Brazil. In addition, we identified important plant species through occurrence and phytosociological parameters for ecological restoration projects in the affected region, serving as reference areas. We sampled plant species with DBH ≥ 5 cm (diameter at breast height – measured 1.30 m above ground level) in 77 plots distributed in three riparian forest areas. We calculated phytosociological parameters and related them to edaphic factors. A total of 1579 individual plants belonging to 53 botanical families and 227 species were sampled in the three areas. The Fabaceae family was the most representative with 46 species. Species composition and diversity among the sampled areas was similar and was associated with edaphic factors. Furthermore, some species (e.g. Xylopia sericea, Cupania emarginata and Ocotea pulchalla) showed an important relation with soil variables. Some species of the genera (e.g. Byrsonima, Xylopia, Ocotea and Croton) and families (e.g. Fabaceae and Myrtaceae) found here, can be important species in the restauration process for the local and regional maintenance of floristic identity in the Rio Doce river.
