Screening Universal COⅠ Primers for eDNA Metabarcoding of Freshwater Fishes on Hainan Island

Progress in Fishery Sciences, 2023
The known universal primers for environmental DNA (eDNA) metabarcoding of fish are mainly located in the mitochondrial ribosome gene regions. Not only are the reference sequences insufficient but also some relative fish species could not be identified ...

The California environmental DNA “CALeDNA” program [PDF]

, 2019
Abstract Global change is leading to habitat shifts that threaten species persistence throughout California’s unique ecosystems. Baseline biodiversity data provide opportunities for ecosystems to be managed for community complexity and connectivity.

Metagenomics: DNA sequencing of environmental samples [PDF]

Nature Reviews Genetics, 2005
Although genomics has classically focused on pure, easy-to-obtain samples, such as microbes that grow readily in culture or large animals and plants, these organisms represent only a fraction of the living or once-living organisms of interest. Many species are difficult to study in isolation because they fail to grow in laboratory culture, depend on ...

Fecal sample collection methods and time of day impact microbiome composition and short chain fatty acid concentrations

Scientific Reports, 2021
Associations between the human gut microbiome and health outcomes continues to be of great interest, although fecal sample collection methods which impact microbiome studies are sometimes neglected. Here, we expand on previous work in sample optimization,

Persistence of environmental DNA in marine systems [PDF]

Communications Biology, 2018
AbstractAs environmental DNA (eDNA) becomes an increasingly valuable resource for marine ecosystem monitoring, understanding variation in its persistence across contrasting environments is critical. Here, we quantify the breakdown of macrobial eDNA over a spatio-temporal axis of locally extreme conditions, varying from ocean-influenced offshore to ...

The complete mitochondrial genome of the Mekong Giant Salmon Carp (Aaptosyax grypus): a tool to conserve an emblematic and elusive megafish

Knowledge and Management of Aquatic Ecosystems
The giant salmon carp is a Critically Endangered megafish from the Mekong River. Despite its emblematic species status, it is rarely observed, and less than 30 confirmed specimens have been recorded since the original species description in 1991.

Investigation of the first recent crayfish plague outbreak in Ireland and its subsequent spread in the Bruskey River and surrounding areas

Knowledge and Management of Aquatic Ecosystems, 2022
White-clawed crayfish (Austropotamobius pallipes) is a keystone species found in western European freshwater bodies, where it has suffered drastic declines due to pathogens, competition with non-indigenous crayfish species (NICS) and habitat ...

eDIY-sampler: an effective low-cost, compact and reproducible filtration system for aquatic eDNA sampling

Knowledge and Management of Aquatic Ecosystems
Environmental DNA (eDNA) methods are now commonly used for aquatic biodiversity monitoring, yet a lack of protocol standardization and the high cost of commercial samplers hinder broader application and results comparisons.

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.

Persistence of Environmental DNA in Freshwater Ecosystems

PLoS ONE, 2011
The precise knowledge of species distribution is a key step in conservation biology. However, species detection can be extremely difficult in many environments, specific life stages and in populations at very low density. The aim of this study was to improve the knowledge on DNA persistence in water in order to confirm the presence of the focus species
