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 ...

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

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. Conventional methods to detect parasites in the environment are cumbersome and have

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

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 Role of Methylation of DNA in Environmental Adaptation [PDF]

Integrative and Comparative Biology, 2013
Methylation of DNA is an epigenetic mechanism that influences patterns of gene expression. DNA methylation marks contribute to adaptive phenotypic variation but are erased during development. The role of DNA methylation in adaptive evolution is therefore unclear.

Survival of environmental DNA in sediments: Mineralogic control on DNA taphonomy [PDF]

Environmental DNA, 2020
Abstract Extraction of environmental DNA (eDNA) from sediments are providing ground-breaking views of the past ecosystems and biodiversity. Despite this rich source of information, it is still unclear which sediments favour preservation and why.

The California environmental DNA “CALeDNA” program [PDF]

, 2019
Abstract Global change is leading to habitat shifts that threaten species persistence throughout California’s unique ecosystems. Baseline biodiversity data provide opportunities for ecosystems to be managed for community complexity and connectivity.

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 ...
