Review of the Role of Bees as Ecosystem Engineers in Nature

Abstract

Bees are a highly important group, providing a multitude of services to ecosystems, most notably through pollination. While much of the research on bees has traditionally focused on their role in pollinating a variety of wild and cultivated crops, this review paper expands the discourse by examining their functions as ecosystem engineers. Traditional definitions of ecosystem engineers exclude pollinators due to their nonphysical modifications of habitats for other species. However, contemporary studies challenge this perspective, recognizing pollinators as integral ecosystem engineers who offer a range of direct and indirect ecological services. For instance, bees’ pollination activities lead to the formation of dry fruits that subsequently serve as shelters for various organisms. In addition, ground-nesting bees modify soil composition through mechanisms such as aeration and bioturbation. This review aims to elucidate the transformative impact bees have as ecosystem engineers, thereby enhancing our understanding of their ecological importance.
