Mechanisms and ecological implications of the movement of bacteria in soil (2018, background): “Finally, it may be (horizontally) transferred into bacterial cells, spurring adaptive processes (Nielsen et al., 2007).”
The ecology of environmental DNA and implications for conservation genetics (2016, background): “…of biological and environmental study use DNA to detect various taxa across many different types of environments, including forensics (van Oorschot et al. 2010), fecal pollution tracking (Caldwell et al. 2011), paleogenetics (Pedersen et al. 2015), and environmental biosafety (Nielsen et al. 2007).”
Critical considerations for the application of environmental DNA methods to detect aquatic species (2016, background): “Environmental DNA begins to decay immediately after shedding (Thomsen et al. 2012a,b); this process continues after sample collection due to mechanical forces, microbial activity (nucleases) and spontaneous chemical reactions (oxygenation, Lindahl 1993; Nielsen et al. 2007).”
Environmental DNA - An emerging tool in conservation for monitoring past and present biodiversity (2015, background): “The macrobial eDNA may in some systems exists predominantly inside mitochondria or small cells (Turner et al., 2014), but owing to eventual membrane degradation, extracellular DNA will also be present in the environment (Nielsen et al., 2007).”
Extracellular DNA in soil and sediment: fate and ecological relevance (2009, background): “…by microorganisms located out of the specific micropore (Blum et al. 1997; Benedik and Strych 1998; Nielsen 2003; Nielsen et al. 2004) because during the diffusion of these enzymes to the eDNA, they can be adsorbed by soil particles or degraded by extracellular proteases (Nielsen et al. 2007).”
Relic DNA is abundant in soil and obscures estimates of soil microbial diversity (2016, methodology): “Conversely, it is unlikely that our approach removed DNA from living cells because (1) studies have shown the effects of PMA on intact microbial cells are minimal and PMA primarily targets extracellular DNA or DNA from cells that are no longer intact4,16,18,19; (2) our own tests confirmed PMA treatm”
Experimental observations on the decay of environmental DNA from bighead and silver carps (2017, background): “The significant influence of microbial extracellular enzymes on the fate of extracellular DNA is well known (Nielsen et al. 2007), while the fate of encapsulated eDNA (e.g. free mitochondria), which can constitute a significant fraction of eDNA in aquatic systems (Turner et al. 2014; Wilcox et al.…”
