Scientific Reports, 2020 Subterranean ecosystems are understudied and challenging to conventionally survey given the inaccessibility of underground voids and networks. In this study, we conducted a eukaryotic environmental DNA (eDNA) metabarcoding survey across the karst ...

Ancient DNA preserved in small bone fragments from the P.W. Lund collection
Ecology and Evolution, 2021 The Lund collection is one of the oldest subfossil collections in the world. The vast assemblage of subfossils was collected in the 1830s and 1840s by Peter Wilhelm Lund in Lagoa Santa, Brazil, and was shipped to Copenhagen in 1848, where it was stored ...

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].

Revising the range of Rocky Mountain tailed frog, Ascaphus montanus, in British Columbia, Canada, using environmental DNA methods [PDF]
, 2020 The Rocky Mountain tailed frog, Ascaphus montanus , is a species at‐risk in Canada. Based upon time‐ and area‐constrained physical search surveys completed between 1996 and 2004, its Canadian distribution was defined as occurring in 19 tributaries and ...

Accurate quantification of microorganisms in PCR-inhibiting environmental DNA extracts by a novel Internal Amplification Control approach using Biotrove OpenArrays [PDF]
, 2009 PCR-based detection assays are prone to inhibition by substances present in environmental samples, thereby potentially leading to inaccurate target quantification or false-negative results.

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.
