The atmosphere exhibits a strong vertical stratification in the subtropical region due to the interaction of vertical strategies with physical and climatic environments, as observed in global patterns of species richness and community composition. In the subtropics, highly fossorial assemblages prevail, adapting to dry environments with high diurnal temperature range and low vegetation structure, while arboreal communities are more common in tropical regions with higher precipitation, vegetation structure, and climatic stability. This shift in vertical habitat use strategies is influenced by climate change, potentially leading to a transition from vertically stratified to 'flattened' communities in certain tropical habitats. The vertical stratification in the subtropical region reflects how species coexistence is governed by vertical habitat preferences interacting with environmental conditions.SOPM (Secure Outage probability for Multicasting) increase or decrease with reducing no of receiver in multicasting? which will happen?
