Research ArticleOpen accessEvery word in the titleThe Impact of Changes in Forage Vegetation for Saiga (Saiga Tatarica) On Natural Pastures in The Steppe Zone of the West Kazakhstan RegionAmanay Myrzabayev, Zhanbolat Ibraibekov, Zhangeldi Ussenov et al.This study investigates the impact of recent climate changes and reduced anthropogenic pressure on the vegetation cover in the steppe regions of Russia and Kazakhstan, particularly focusing on the effects on saiga (Saiga tatarica) populations. By the late 1990s, a significant shift towards the dominance of grasses and the reduction of herbaceous plants in semi-arid and arid regions was observed, … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 7 Feb 2026 · 1,765 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Altitude on Species Diversity and Vegetation Structure of Kigelia africana Parklands in CameroonAwé Djongmo Victor, Vroh Bi Tra Aimé, Noiha Noumi Valery et al.In the Faro Subdivision (North, Cameroon), there are populations of Kigelia africana, known by the common name “Dambale", whose variety is largely unknown. The study's goal is to demonstrate how altitude affects species diversity and vegetation structure in Kigelia africana parklands. To gather information for statistical analysis, a Randomized Complete Block Design (RCBD) was employed. A total of 90 quadrats … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 20 Dec 2025 · 3,176 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Study of Seasonal Patterns in Vegetation Diversity and Forage Yield DynamicsSema, Jasmal Ahmari Syamsu et al.This study examines the seasonal dynamics of vegetation diversity, forage yield, and nutrient quality in Tarabbi Village, Malili District, East Luwu Regency, conducted from July 2023 to July 2024. Using a survey approach and field measurements, data were collected through the Estimated Actual Weight method and Summed Dominance Ratio (SDR), complemented by Geographic Information System (GIS) technology for analysis.
