Abstract

In this closing chapter, we summarize the advances in biological soil crust (biocrust) research made during the last 1.5 decades. In the first part of the chapter, we discuss how in some research fields, such as the microbial diversity of fungi, bacteria, and microfauna, the interaction between biocrusts and vascular plants, and in the rehabilitation of biocrusts, particularly large achievements have been made. We also review the corroboration and refinement of previously established knowledge in other research areas, e.g., in the fields of soil stabilization and disturbance effects.

In the second part of the chapter, we outline the research gaps and challenges foreseen by us. We identify multiple knowledge gaps, including many understudied geographic regions, the largely missing link between genetic and morphological species identification data, and the answers to some mechanistic questions, such as the overall role of biocrusts in hydrology and nutrient cycles. With some ideas on promising new research questions and approaches, we close this chapter and the overall book.
