Sedimentary DNA for tracking the long-term changes in biodiversity.Understanding long-term dynamics is vitally important for explaining current biodiversity patterns and setting conservation goals in a changing world.  The sedimentary DNA (sedDNA) has a great potential for paleo-community reconstruction, and it has recently been used as a powerful tool to characterize past dynamics in terms of biodiversity over geological timescales. 
Sedimentary DNA
The sedimentary DNA (sedDNA) has a great potential for paleo-community reconstruction, and it has recently been used as a powerful tool to characterize past dynamics in terms of biodiversity over geological timescales.  Here, a "Research Weaving" method was performed with systematic maps and bibliometric webs based on the Web of Science for Science Citation Index Expanded, presenting a comprehensive landscape of the sedDNA that traces biological dynamics.  We identified that most sedDNA-based studies have focused on microbial dynamics and on using samples from multitypes of sediments.  This review summarized the advantages and common applications of sedDNA, focused on the biodiversity in microbial communities, and provided an outlook for the future of sedDNA research.
