The effect of tides on nearshore environmental DNA

摘要: We can recover genetic information from organisms of all kinds using environmental sampling. In recent years, sequencing this DNA (eDNA) has become a tractable means surveying many species water, air, or soil samples. The technique is beginning to core tool for ecologists, scientists, and biologists kinds, but the temporal resolution eDNA sampling often unclear, limiting ecological interpretations resulting datasets. Here, in temporally spatially replicated field study ca. 313 bp eukaryotic COI mtDNA as marker, we find that nearshore organismal communities are largely consistent across tides. Our findings suggest both benthic planktonic taxa tends be endogenous site water mass sampled, rather than changing with each tidal cycle. However, where physiochemical characteristics change, relative contributions broad range shift concert.
