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

Is There a Causal Association between Genotoxicity and the Imposex Effect? [PDF]
, 2006 There is a growing body of evidence that indicates common environmental pollutants are capable of disrupting reproductive and developmental processes by interfering with the actions of endogenous hormones.

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 ...

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 ...

Evaluating detection limits of next-generation sequencing for the surveillance and monitoring of international marine pests [PDF]
, 2013 Most surveillance programmes for marine invasive species (MIS) require considerable taxonomic expertise, are laborious, and are unable to identify species at larval or juvenile stages.

DNA repair systems and the pathogenesis of Mycobacterium tuberculosis: varying activities at different stages of infection [PDF]
, 2010 Mycobacteria, including most of all MTB (Mycobacterium tuberculosis), cause pathogenic infections in humans and, during the infectious process, are exposed to a range of environmental insults, including the host's immune response.

An integrative assessment to determine the genotoxic hazard of estuarine sediments: combining cell and whole-organism responses [PDF]
, 2014 The application of the Comet assay in environmental monitoring remains challenging in face of the complexity of environmental stressors, e.g., when dealing with estuarine sediments, that hampers the drawing of cause-effect relationships.

The effect of tides on nearshore environmental DNA
PeerJ, 2017 Organisms of all kinds leave genetic traces in their environments, and in recent years, sequencing this environmental DNA (eDNA) has become a tractable means of surveying many species using water, air, or soil samples. The technique is beginning to become a core tool for ecologists, environmental scientists, and biologists of many kinds, but the ...
