Some species including honey bees, bumblebees, and stingless bees live socially in colonies. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bee pollination is important both ecologically and commercially; …show more content…
Multiple mechanisms is triggered by various processes which leads to coexistence of ecologically similar species within these mutualist guilds (Palmer et al., 2003). One important mechanism that facilitates species coexistence is resource partitioning (Schoener., 1974, Tilman., 1982). Tendency of occurrence of resource partitioning is most likely to occur in heterogeneous environments that is sparsely dispersed, which is characterized by different species that can specialize on distinct resources, exploit resources at different times, or utilizing resources in different regions (Amarasekare., 2003). If space is separated, variety of species can occupy different niches from the local scale of a resource patches to the topographical scale of divergent landscapes containing multiple patches of several resources. Thus, more species have the ability to coexist across different spatial scales. (Kneitel and Chase.,
