In the Memory of Our Teacher

Students, colleagues, and friends of Bella Rafailovna Striganova as well as the Editorial Board of the journal Biology Bulletin, which she headed for many years, dedicate this issue of the journal to her memory.

Striganova: regularities of geographic changes in taxonomic diversity, abundance, and landscape distribution of soil communities; trophic relations of pedobionts and zoomicrobial relationships; functioning of detrital food webs; the importance, conservation, and rational use of the biological diversity of natural systems; soil zoology and problems of the national economy; problems of evolutionary theory.
