“…7 ). Moreover, the structural composition and species diversity indices of plant communities show specific patterns of differentiation and gradient ( Gebrehiwot et al., 2020 ), as topographical factors (elevation, aspect, slope, and slope position) affect the distribution of vegetation ( Fig. 7 ), and in turn they jointly affect the redistribution of water, temperature, nutrients, light, and other materials and energy.…”

“…Evergreen-deciduous broadleaved mixed forest is a forest vegetation type between deciduous broadleaved forest and evergreen broadleaved forest ( Huang et al., 2015 ). At present, studies on evergreen-deciduous broadleaved forest mainly focus on the basic concept ( Nkosi et al., 2016 ), spatial distribution ( Li et al., 2010 ), species composition ( Yun et al., 2020 ), community renewal ( Gebrehiwot et al., 2020 ), invasion of alien species ( Iturrate-Garcia et al., 2016 ), and distribution of rare and endangered species ( Yang et al., 2019 ). However, these studies have rarely examined how topographical and soil nutrient factors in evergreen-deciduous broadleaved mixed forest drive variation in mountain plant community types or quantified the relative contribution of each driver.…”

Topography and soil factors are known to play crucial roles in the species composition of plant communities in subtropical evergreen-deciduous broadleaved mixed forests. In this study, we used a systematic quantitative approach to classify plant community types in the subtropical forests of Hubei Province (central China), and then quantified the relative contribution of drivers responsible for variation in species composition and diversity. We classified the subtropical forests in the study area into 12 community types. Of these, species diversity indices of three communities were significantly higher than those of others. In each community type, species richness, abundance, basal area and importance values of evergreen and deciduous species were different. In most community types, deciduous species richness was higher than that of evergreen species. Linear regression analysis showed that the dominant factors that affect species composition in each community type are elevation, slope, aspect, soil nitrogen content, and soil phosphorus content. Furthermore, structural equation modeling analysis showed that the majority of variance in species composition of plant communities can be explained by elevation, aspect, soil water content, litterfall, total nitrogen, and total phosphorus. Thus, the major factors that affect evergreen and deciduous species distribution across the 12 community types in subtropical evergreen-deciduous broadleaved mixed forests include elevation, slope and aspect, soil total nitrogen content, soil total phosphorus content, soil available nitrogen content and soil available phosphorus content.

Ethiopia is a mountainous country with great geographic diversity. The diversified topographic features in Ethiopia made the country have a rich biodiversity forest cover in tropical Africa. This made Ethiopia have the largest floral diversity in tropical Africa. This floral diversity is rich in endemic elements. About 6,027 vascular plant species (including subspecies) with about 10.7% endemism have been documented. Plant community types are primarily influenced by topographic factors, as well as disturbance and environmental factors. The objective of this study is to demonstrate that 1: The forest patches in the study area exhibit distinct plant community types. 2: The composition and structure of these plant communities are influenced by various environmental variables. To achieve this, a total of 76 plots were used to collect vegetation and environmental data. The collected data were then analyzed using the R software, employing agglomerative hierarchical cluster analysis and redundancy analysis (RDA) to identify plant communities and assess the relationship between these communities and environmental variables.R software was used to identify plant communities and analyze the relationship between plant community types and environmental variables using agglomerative hierarchical cluster analysis and redundancy analysis (RDA). Four plant community types were identified. The RDA results highlighted the significant impact (p < 0.005) of altitude, aspect, slope, grazing, and human interference on species distribution and the formation of plant communities. The RDA results highlighted the significant impact (p < 0.005) of altitude, aspect, slope, grazing, and human interference on species distribution and the formation of plant communities.The findings indicate that the variation in plant communities is closely associated with topographic factors such as altitude, slope, aspect, as well as disturbance factors like grazing, and human interference, with altitude being the most influential factor. Based on these findings, it is recommended that conservation plans take into consideration the effects of grazing and human interference in order to address the challenges faced in conserving forest patches in the future.Additionally, further research efforts should focus on mitigating disturbance factors and understanding the environmental variables that affect forest patches to enhance their conservation.

“…Ethiopia is a country with a very complex topography with elevation varying from about 125 m below sea level to about 4 533 m above sea level (m.a.s.l.) (Gebrehiwot et al 2020). Two of the 36 biodiversity hotspots, the Eastern Afromontane and the Horn of Africa, are found in Ethiopia (Mittermeier et al 2004;Hoffman et al 2016;Gebrehiwot et al 2020).…”

Background: The current status of plant ecology research in Ethiopia is unknown with the result that it is challenging to judge the impact of existing research on policy development and conservation actions.Objectives: The objective of this paper was to systematically analyse the trends in plant ecological research in Ethiopia over the past 50 years.Methods: The inclusion and exclusion of articles for analysis was carried out using the Reporting Standards for Systematic Evidence Syntheses (ROSES) flow diagram developed for systematic review/meta-analysis.Results: The number of articles published, authors and collaboration has increased dramatically since the 1960s. Most of the research (52.6%) focused on the Dry evergreen Afromontane Forest and grassland complex (DAF) and Moist evergreen Afromontane Forest (MAF) vegetation types. Of the remaining vegetation types, woodlands (14.3%) i.e. Acacia–Commiphora woodland and bushland proper (ACW), and Combretum–Terminalia woodland and wooded grassland (CTW), desert and semi-desert scrubland (DSS) (2.3%), and the Afroalpine (AA) and Ericaceous Belt (EB) (1.5%) received comparatively little attention. Classical plant ecology themes and descriptive plant community studies were dominant over the last five decades in contrast to the focus on contemporary themes globally. Reproductive and dispersal ecology of invasive plant species and pollination ecology seem to be largely neglected topics. Furthermore, the recommendations forwarded by most of the articles reviewed (38.1%, n = 51) were not result-based. Conclusions: As a future direction, the Ethiopian government should develop a project database for both completed and ongoing projects.
