Getting to the Root of Organic Inputs in Groundwaters: Stygofaunal Plant Consumption in a Calcrete Aquifer

open access: yesFrontiers in Ecology and Evolution, 2022
Groundwater environments interact with and support subterranean biota as well as superficial aquatic and terrestrial ecosystems. However, knowledge of subterranean energy flows remains incomplete.

On a roll: a direct comparison of extraction methods for the recovery of eDNA from roller swabbing of surfaces

open access: yesBMC Research Notes, 2023
Objective Roller swabbing of surfaces is an effective way to obtain environmental DNA, but the current DNA extraction method for these samples is equipment heavy, time consuming, and increases potential contamination through multiple handling.

The complete mitochondrial genome of the invasive cyanobacteriosponge Terpios hoshinota (Demospongiae, Suberitida, Suberitidae)

open access: yesMitochondrial DNA. Part B. Resources, 2023
The cyanobacteriosponge Terpios hoshinota occurs on tropical reefs throughout the Indo-Pacific. The species encrusts live coral, and other benthos, and is considered a pest species that can threaten the health and productivity of locally native benthic ...

Rock pools as a source of environmental DNA for the detection of the threatened Pilbara olive python (Liasis olivaceus barroni)

open access: yesFrontiers in Environmental Science, 2023
Environmental DNA (eDNA) research is transforming biomonitoring at a global scale, but applicability to reptiles has been restricted because of their presumed low shedding rate. Consequently, eDNA may have considerable limitations as a biomonitoring tool

Characterizing the distribution of the critically endangered estuarine pipefish (Syngnathus watermeyeri) across its range using environmental DNA

open access: yesEnvironmental DNA, 2023
The effective management of rare and threatened species, especially in areas where population sizes have diminished, relies on knowledge of their population size, threats, and distribution.

DNA Leaves a Trace [PDF]

open access: yesScience, 2012
Ecology![Figure][1] CREDIT: ISTOCKPHOTO.COM Detecting the presence of populations of rare and threatened animal species is a challenge for conservation planners and managers, especially in habitats like lakes and rivers, where an animal leaves little or no macroscopic trace. Thomsen et al.

Recovery techniques for contact DNA traces

open access: yesArchives of Forensic Medicine and Criminology, 2023
Donor DNA profiling can serve at least two purposes: 1) to enhance the evidential value of DNA deposited on garments/ items and 2) to provide valuable tactical information during crime scene investigation. In this review, different types of methods for the recovery of the contact DNA traces have been summarized.

Coral monitoring in northwest Australia with environmental DNA metabarcoding using a curated reference database for optimized detection

open access: yesEnvironmental DNA, 2022
The need for efficient and more accurate ways of monitoring threatened ecosystems is becoming increasingly urgent as climate change intensifies. Coral reefs are an example of an ecosystem in crisis, with widespread declines in coral cover and diversity ...

The Detection of Cancer Epigenetic Traces in Cell-Free DNA [PDF]

open access: yesFrontiers in Oncology, 2021
Nucleic acid fragments found in blood circulation originate mostly from dying cells and carry signs pointing to specific features of the parental cell types. Deciphering these clues may be transformative for numerous research and clinical applications but strongly depends on the development and implementation of robust analytical methods.
