Seasonal variation in environmental DNA in relation to population size and environmental factors [PDF]
Scientific Reports, 2017 AbstractAnalysing DNA that organisms release into the environment (environmental DNA, or eDNA) has enormous potential for assessing rare and cryptic species. At present the method is only reliably used to assess the presence-absence of species in natural environments, as seasonal influences on eDNA in relation to presence, abundance, life stages and ...

DNA energy constraints shape biological evolutionary trajectories [PDF]
arXiv, 2019 Most living systems rely on double-stranded DNA (dsDNA) to store their genetic information and perpetuate themselves. This biological information has been considered the main target of evolution. However, here we show that symmetries and patterns in the dsDNA sequence can emerge from the physical peculiarities of the dsDNA molecule itself and the ...

Environmental DNA for conservation
, 2021 Abstract Detection and monitoring of wildlife species of concern is a costly and time-consuming challenge that is critical to the management of such species. Tools such as lures and traps can cause unnecessary stress or other health impacts to sensitive species.

Improving Taxonomic Image-based Out-of-distribution Detection With DNA Barcodes [PDF]
Image-based species identification could help scaling biodiversity monitoring to a global scale. Many challenges still need to be solved in order to implement these systems in real-world applications. A reliable image-based monitoring system must detect out-of-distribution (OOD) classes it has not been presented before.

Effect of environmental noise on charge diffusion in DNA: Towards modeling its potential epigenetic impact in live processes [PDF]
arXivCharge diffusion through desoxyribonucleic acid (DNA) is a physico-chemical phenomenon that on the one hand is being explored for technological purposes, on the other hand is applied by nature for various informational processes in life. With regard to the latter, increasing experimental and theoretical evidence indicates that charge diffusion through ...

Does quantum entanglement in DNA synchronize the catalytic centers of type II restriction endonucleases? [PDF]
arXiv, 2014 Several living systems have been examined for their apparent optimization of structure and function for quantum behavior at biological length scales. Orthodox type II endonucleases, the largest class of restriction enzymes, recognize four-to-eight base pair sequences of palindromic DNA, cut both strands symmetrically, and act without an external ...

CompostBin: A DNA composition-based algorithm for binning environmental shotgun reads [PDF]
arXiv, 2007 A major hindrance to studies of microbial diversity has been that the vast majority of microbes cannot be cultured in the laboratory and thus are not amenable to traditional methods of characterization. Environmental shotgun sequencing (ESS) overcomes this hurdle by sequencing the DNA from the organisms present in a microbial community.

Estimation of Fish Biomass Using Environmental DNA
PLoS ONE, 2012 Environmental DNA (eDNA) from aquatic vertebrates has recently been used to estimate the presence of a species. We hypothesized that fish release DNA into the water at a rate commensurate with their biomass. Thus, the concentration of eDNA of a target species may be used to estimate the species biomass.

Starr: Simple Tiling Array Analysis of Affymetrix ChIP-chip data [PDF]
arXiv, 2009 Chromatin immunoprecipitation combined with DNA microarrays (ChIP-chip) is an assay for DNA-protein-binding or post-translational chromatin/histone modifications. As with all high-throughput technologies, it requires a thorough bioinformatic processing of the data for which there is no standard yet.
