“…A total shift in the composition of the vegetation served as the basis for the selection of three distinct elevations: 1600 m, 1950 m, and 2650 m [9]. Four samplings were conducted in each of the four directions from the chosen elevation, centered on the wholesome tree composition, following the recommendation of [12]. In order to distinguish trees from shrubs and other woody plants, the following variables were noted in each sample plot: species, number, diameter, and cut stumps in study plots.…”

The floral community changes in elevation. Due to the more diverse ecological characteristics, the diverse flora, and the number of landscape elements, there is a change in diversity called the edge effect. This study examines the role of altitude (1400–1800 m, 1800–2400 m, and above 2400 m) and how floral diversity changes with altitude variation. The aim of this study is to examine the carbon stock at which altitudinal range it is higher and why. One tree species (oak) was found at highest altitude (2650 m) followed by intermediate altitude (2100 m) further with greatest number of tree species at low altitude (1600 m). Higher species diversity (Shanon Index: 2.1863) and density (5575 individuals per hectares) was found at altitudinal range I (1400 to 1800 m) composed by Rhododendrum arborium, Quercus glauca, Myrica esculenta, and Myrsine capitellat. Whereas Rhododendron arboretum, Castanopsis tribuloides, and Quercus incana dominate altitudinal range II (1800m to 2400m) with diversity (Shannon Index: 1.759) and an average density (2150 individuals per hectare). In Altitudinal Area III (2400 m and above), the forest is dominated by Quercus semicarpifolia. The highest carbon stock was found in the altitudinal range (1800m to 2400m) compared to altitudinal ranges I and III. Edge effects shaped the community composition and affected tree diversity and carbon stock. In conclusion, the floral community and carbon stock were affected by forest edges, which led to conservation actions and mitigation of climate change in surprisingly different ways.

“…Losses of several plant species worldwide have been attributed to temperature fluctuations [ 85 ]. Climate change is one of the major problems of the 21st century [ 86 ]. Climatic changes due to temperature variation have also been reported to result in decreased pollination and seed production [ 87 ].…”

The genus Taxus (yews) is the largest genus of the family Taxaceae. It comprises about 24 species with 55 varieties distributed mainly in Asia, Europe, North Africa, and North America. In addition to the taxane diterpenoids and the cancer drug taxol, its species contain many essential oils with actual or potential biological activity. This review covers the chemical constituents as well as biological activities of these oils that have been studied in fourteen countries over 46 years (1975–2021). It also discusses the biotic and abiotic factors that limit the regeneration of these economically and medicinally important plants.
