Scope and approach: The purpose of this review is to raise potential applications for coffee by-products in topical formulations. Besides, to present the main bioactive compounds responsible for their biological activity.
Soil organic matter (OM) stratification and macro and micro fauna are both good indicators for the evaluation of soil ecological functioning, which is interrelated with nutrient cycles. To the best of the authors’ knowledge, responses of the degree of OM stratification with soil depth expressed as a ratio, and belowground biota to forest degradation and land cover changes have received little attention, particularly in northern Iran.
