The future of environmental DNA in ecology

Molecular Ecology, 2012
The contributions of environmental DNA to ecology are reviewed, focusing on diet, trophic interactions, species distributions and biodiversity assessment. Environmental DNA has the potential to dramatically improve quantitative studies in these fields.

Environmental DNA: The next chapter

Molecular Ecology
AbstractMolecular tools are an indispensable part of ecology and biodiversity sciences and implemented across all biomes. About a decade ago, the use and implementation of environmental DNA (eDNA) to detect biodiversity signals extracted from environmental samples opened new avenues of research. Initial eDNA research focused on understanding population

Environmental DNA Time Series in Ecology

Trends in Ecology & Evolution, 2018
Ecological communities change in time and space, but long-term dynamics at the century-to-millennia scale are poorly documented due to lack of relevant data sets. Nevertheless, understanding long-term dynamics is important for explaining present-day biodiversity patterns and placing conservation goals in a historical context.

Environmental implications of recombinant DNA technology

Biotechnology Advances, 1986
Applications of recombinant DNA technology are discussed as a backdrop for evaluation of the environmental impacts of this technology. Some of applications include using traditional biological techniques for specific purposes, including nitrogen fixation, microbial pesticides, and waste treatment.

Characterization of human DNA in environmental samples

Forensic Science International, 2008
Environmental samples from indoor surfaces can be confounded by dust, which is composed largely of human skin cells and has been documented to contain roughly tens of micrograms of total DNA per gram of dust. This study complements previous published work by providing estimates of the quantity of amplifiable human DNA found in environmental samples ...

DNA Microarray Applications in Environmental Microbiology

Analytical Letters, 2003
Although the majority of microarray reports are concerned with gene expression profiling in health-related studies, the use of DNA microarray technology is expanding into new fields and new applications. In environmental microbiology, developments are also focusing on the detection of specific sequences in complex environmental samples and on genomic ...

Environmental DNA for functional diversity

2018
Abstract Chapter 10 “Environmental DNA for functional diversity” discusses the potential of environmental DNA to assess functional diversity. It first focuses on DNA metabarcoding and discusses the extent to which this approach can be used and/or optimized to retrieve meaningful information on the functions of the target community.

DNA as a Biosensor for Environmental Agents

1991
It is the thesis of this paper that DNA can be utilized as a target to detect environmental agents that can modify DNA directly or indirectly through metabolic activation. Expression of DNA modification will be achieved by using as a target a bacterial gene encoding an easily assessable enzyme.

Introduction to environmental DNA (eDNA)

2018
Abstract Chapter “Introduction to environmental DNA (eDNA)” defines the central concepts of this book. Environmental DNA (eDNA) corresponds to a mixture of genomic DNA from many different organisms found in an environmental sample such as water, soil, or feces. DNA metabarcoding can be defined as the simultaneous DNA-based identification

Electrochemical DNA biosensor for environmental monitoring

Analytica Chimica Acta, 2001
Abstract A disposable electrochemical DNA biosensor for the determination of toxic aromatic amines has been developed. The device relies on the intercalative or electrostatic collection of aromatic amines onto an immobilized dsDNA or ssDNA layer (obtained from several sources), followed by a chronopotentiometric analysis.
