Ancient and modern environmental DNA [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2015 DNA obtained from environmental samples such as sediments, ice or water (environmental DNA, eDNA), represents an important source of information on past and present biodiversity. It has revealed an ancient forest in Greenland, extended by several thousand years the survival dates for mainland woolly mammoth in Alaska, and pushed back the dates for ...

Persistence of environmental DNA in marine systems [PDF]
Communications Biology, 2018 AbstractAs environmental DNA (eDNA) becomes an increasingly valuable resource for marine ecosystem monitoring, understanding variation in its persistence across contrasting environments is critical. Here, we quantify the breakdown of macrobial eDNA over a spatio-temporal axis of locally extreme conditions, varying from ocean-influenced offshore to ...

Biodiversity monitoring using environmental DNA
Molecular Ecology Resources, 2021 Monitoring biodiversity is essential to protect, preserve and restore ecosystems, particularly in the context of current challenges such as climate change, habitat destruction and globalization (Baird & Hajibabaei, 2012). Biomonitoring is needed for developing biotic indices for assessing ecological status, measuring impacts of anthropogenic activities

Environmental DNA for improved detection and environmental surveillance of schistosomiasis [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance Accurate detection and delineation of schistosomiasis transmission sites will be vital in ongoing efforts to control and ultimately eliminate one of the most neglected tropical parasitic diseases affecting >250 million people worldwide.

Sponges as natural environmental DNA samplers [PDF]
Current Biology, 2019 At a time of unprecedented impacts on marine biodiversity, scientists are rapidly becoming persuaded by the potential of screening large swathes of the oceans through the retrieval, amplification and sequencing of trace DNA fragments left behind by marine organisms; an approach known as 'environmental DNA' (eDNA) [1].

The Future of Environmental DNA in Forensic Science [PDF]
Applied and Environmental Microbiology, 2020 DNA sequencing technologies continue to improve, and there has been a corresponding expansion of DNA-based applications in the forensic sciences. DNA recovered from dust and environmental debris can be used to identify the organisms associated with these sample types, including bacteria, plants, fungi, and insects. Such results can then be leveraged to

Metagenomics: DNA sequencing of environmental samples [PDF]
Nature Reviews Genetics, 2005 Although genomics has classically focused on pure, easy-to-obtain samples, such as microbes that grow readily in culture or large animals and plants, these organisms represent only a fraction of the living or once-living organisms of interest. Many species are difficult to study in isolation because they fail to grow in laboratory culture, depend on ...

Challenges to Implementing Environmental-DNA Monitoring in Namibia [PDF]
Frontiers in Environmental Science, 2022 By identifying fragments of DNA in the environment, eDNA approaches present a promising tool for monitoring biodiversity in a cost-effective way. This is particularly pertinent for countries where traditional morphological monitoring has been sparse. The first step to realising the potential of eDNA is to develop methodologies that are adapted to local

Influence of Environmental Parameters on the Stability of the DNA Molecule [PDF]
Entropy, 2021 Fluctuations in viscosity within the cell nucleus have wide limits. When a DNA molecule passes from the region of high viscosity values to the region of low values, open states, denaturation bubbles, and unweaving of DNA strands can occur. Stabilization of the molecule is provided by energy dissipation—dissipation due to interaction with the ...
