Forest vegetation is an important component of forest ecosystems, contributing to terrestrial plant diversity while also providing a variety ecological services. In managed landscapes, plantations emerge as dominant kinds after stand-replacing disturbances. However, the dynamics cover, diversity, and composition in plantation forests remains poorly understood subtropical region. Our study recorded rich floral with 173 angiosperm species, characterized by varying life forms distinct flowering phenology. The uneven distribution species across families demonstrated complexity ecosystem, Poaceae being dominant. Diversity patterns among different types varied, Dalbergia sissoo Populus nigra exhibiting higher richness diversity. Conversely, Eucalyptus camaldulensis Morus alba displayed lower emphasizing influence type on biodiversity. Non-metric multidimensional scaling (nMDS) PERMANOVA analyses revealed significant dissimilarity composition. Indicator analysis identified unique compositions within each type, importance conserving specific protect indicator maintained distinctiveness. Canonical Correspondence Analysis (CCA) that road accessibility, stem cutting, fire significantly influenced patterns. present research underscored considering management for biodiversity conservation highlighted environmental variables’ formation communities. These results provided major implications sustainable efforts tropical regions.

Urban development greatly alters the natural and semi-natural habitats of native plants. Urbanisation results in a range diverse including remnant agricultural lands, urban parks, roadside habitats. This habitat diversity often promotes trait divergence within areas. However, mechanisms by which influence population genetic structure individual plant species remain poorly understood. We investigated effects urbanisation on 24

Abstract With the rapid development of urbanization, natural habitats in many parts world have been seriously damaged by urban expansion. However, expansion is a complex process, and impacts different levels on at regional scales their distance thresholds are still unclear. We conducted study Hubei Province, China to evaluate prefecture-level cities county towns quantity, area, quality critical threshold distances affecting habitats. The results show that, scale, habitat degradation was driven primarily large numbers towns, but affected over greater distances. Specifically, impact town first increased then decreased with from built-up areas, for quantity being approximately 8 km 80 km, respectively. expanding showed similar nonlinear change distance, rose 40 130 These findings not only reverse conventional view that dominates degradation, also draws more attention influence numerous small habitat, when measured scale. Understanding particular spatial can be help inform decision-making regards conservation.

Abstract Spontaneous plants are crucial components of urban biodiversity. The distribution spontaneous can be profoundly affected by their seed dispersal mode and environmental factors in systems. Since a comprehensive investigation into the drivers successful modes is still lacking, we explored impacts natural factors, limitation, habitat quality on diversity pattern plants. We assessed patterns four 16 major cities Yunnan province, most biodiverse province China. A total 1,744 916 genera 175 families were recorded 893 green patches. dominating (13 out 16) was autochory (33.5–38.7%), with hydrochory being least frequent (4.3–10.9%). Our research highlights heavily disturbed anthropogenic ecosystems, such as areas, tend to adopt convergent strategies address stressors. Their richness significantly higher colder humid climates. However, limitations (measured distance city boundary, size urbanization rate) increased decrease (as expressed patch area), all experienced reduction. sensitivities among different these divergent. Hydrochory exhibited strongest sensitivity climate factors. Whereas demonstrated sensitivity, anemochory showed weakest limitation. These results suggest that include improving or creating corridors mitigate limitation between areas surrounding mountains will valuable additions biodiversity conservation efforts.
