“…The increased slope gradient may in uence soil waterholding capacity, resulting in a narrower range of species that can thrive within the same climatic zone in SJ, consequently leading to lower species richness compared to NG. The negative correlation between species richness and slope aligns with previous research (Souza et al 2024). Additionally, the higher slope in SJ may contribute to micro-topographic variations within the region, such as Danxia landforms, providing diverse microhabitats.…”

Background Shrub communities play a crucial role in forest restoration, soil and water conservation, and maintaining ecological balance in terrestrial ecosystems. However, the influence of environmental factors on the distribution characteristics of shrub plants, particularly in the subtropical region of China, remains poorly understood. Materials and methods Two subtropical areas with similar dimensions in southern Jiangxi and northeastern Guangxi, China were examined. We compared species composition, diversity and life forms in two subtropical regions, and quantified the niche width of the same species using Levins index (Bi). Principal Coordinates Analysis (PCoA) and Redundancy Analysis (RDA) were employed to comprehensively explore the relationship between shrub community composition and environmental factors. Results Southern Jiangxi (with 100 recorded shrub species) and northeastern Guangxi (with 108 recorded shrub species) exhibit comparable species richness in their respective shrub communities. Southern Jiangxi had higher species diversity and a more pronounced dominance of certain species compared to northeastern Guangxi. Additionally, northeastern Guangxi had a higher proportion of aboveground-shoot plants and underground-shoot plants compared to southern Jiangxi. The niche width and niche overlap of the same species exhibit significant differences between the two regions. Low similarity in species composition between their respective shrub communities while RDA analysis highlighted significant correlations between soil physicochemical factors (C, N, P, pH), slope aspect with species composition emphasizing variations in explanatory power across different environmental factors. Conclusion Soil factors exert a significant influence on the structure and species composition of shrub communities in subtropical climates, underscoring the intricate interplay between soil properties and vegetation dynamics within ecosystems.

The Atlantic Forest, in the state of Bahia, Brazil, is a fragmented hotspot that faces challenges in order to overcome environmental degradation. Ecological connectivity is one strategy that may mitigate environmental impacts. The objective of the study was to develop a spatial proposal for an ecological corridor between the forest fragment of the UFSB Sosigenes Costa University Campus, the private Natural Heritage Reserve Estação Veracel and the Pau Brasil National Park, as well as understand the mechanisms for the implementation of an ecological corridor that involves different government sectors in possible public-private support strategies. The topographic, socioeconomic, ecological and legal characteristics were evaluated in a geographic information system. Using the minimum cost method, the potential areas were modeled for a spatial mapping of connectivity between the areas. The proposed corridor has a length of 9.78 km, a width of 978.70 m and a total area of 942.70 ha. Due to a predominance of anthropogenic activities, mitigation strategies would be required for its implementation. Public-private partnerships can promote forest connectivity and mitigate threats to the stability of local ecosystems, inside and outside of conservation units, and permanent preservation areas should be prioritized as a source of forest connectivity.

The Ibitipoca Mountains occur in southeastern Minas Gerais state, Southeast Brazil, and includes a mosaic of different vegetation types, as part of the Atlantic Forest domain. Such heterogeneity results in the occurrence of several ecotones in the region, considered essential buffer zones for maintaining biodiversity and structure among adjacent ecosystems. Given the importance of these environments for biodiversity conservation, floristic surveys are important to catalogue plant richness in natural areas, where species and landscapes have been destroyed, especially over the last decades. To contribute to increase the knowledge on the vascular Flora in the Ibitipoca Mountains, a floristic inventory was undertaken in private properties located in the boundaries of “Parque Estadual do Ibitipoca” (Ibitipoca State Park). Relevant findings of the present study include: characterization of the different vegetation types, 17 new records for the Flora of Minas Gerais, collection of 288 species never recorded in the state park (80% dissimilarity – especially due to the occurrence and size of different phytophysiognomies between these areas) and presence of 31 threatened species. In addition, discussions about conservation efforts and public policies are presented.
