Spatial dispersal of environmental DNA particles in lentic and marine ecosystems: An overview and synthesis
Knowledge of the transport of environmental DNA (eDNA) particles, including its downstream transport, dispersal, and deposition, is crucial for properly assessing the spatial scale of its signals in the field. Despite the relative progress in research on riverine eDNA transport, the mechanism of eDNA dispersal in lentic (ponds and lakes) and marine (oceans and coasts) ecosystems remains understudied. Here, we reviewed and integrated the previous findings of horizontal and vertical eDNA dispersal in lentic and marine ecosystems. We showed the lack of studies in these ecosystems and substantial variabilities among their results, which could be induced by a variety of ecological, hydrological, and geographical factors. We also re-analyzed the previous studies to estimate the rates of horizontal eDNA dispersal in lentic and marine ecosystems, indicating that eDNA particles can reach substantially farther in the oceans and coasts than in the ponds and lakes. The literature review and analysis suggested that the level of eDNA dispersal influenced the resolution of eDNA signals to reflect the spatial community structures, which could further pose positive and negative impacts on the eDNA sampling strategy. Future efforts to understand such technical background and relate eDNA dispersal dynamics to environmental parameters will help properly interpret the eDNA detection results and make eDNA analysis more effective for conservation and environmental management.
期刊介绍:
The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published.
• All aspects of ecological and environmental indicators and indices.
• New indicators, and new approaches and methods for indicator development, testing and use.
• Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources.
• Analysis and research of resource, system- and scale-specific indicators.
• Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs.
• How research indicators can be transformed into direct application for management purposes.
• Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators.
• Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
