Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

Experimental assessment of Acanthopagrus schlegelii biomass based on environmental DNA technology

Scientific Reports
The Environmental DNA (eDNA) technology has attracted significant attention due to its convenience and high sensitivity. However, the variations of eDNA across diverse environments and biological species remain complex.

Metabarcoding replicate detection frequency tracks ddPCR copy number for cod and herring eDNA in ancient marine sediments

Methods in Ecology and Evolution, EarlyView.
Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...

From fluke to fragment: A multifaceted method for molecular sex identification and mitochondrial haplotyping from environmental DNA samples

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) analyses have become a powerful tool for non‐invasive biodiversity monitoring, yet the applicability of population‐genetic approaches to environmental samples remains largely unexplored. Even when genetic traces originate from a single individual, low target DNA concentrations and amplification or sequencing artefacts ...

Enhanced fish detection sensitivity in aquatic systems using environmental RNA

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental RNA (eRNA) can potentially augment the biological monitoring ability of the established environmental DNA (eDNA) application in conservation. Despite faster degradation, environmental RNA could offer unique advantages: it may help reduce the legacy signal compared to eDNA, provide insights into physiological status through gene ...

Comparative Efficiency of eDNA, Camera Traps and Scat Surveys to Detect a Semi‐Aquatic Mammal Across Multiple Catchments

Animal Conservation, EarlyView.
Monitoring semi‐aquatic mammals is essential for their conservation, but it is made difficult by their elusive lifestyle and generally low abundance. Eurasian otter (Lutra lutra) monitoring has traditionally relied on scat surveys, but eDNA and camera‐trapping are emerging as promising alternatives.

Continual Day–Night eDNA Detectability Amidst Diel Reef Species Fluctuations on Diver Transects

Environmental DNA
Recent research into the spatiotemporal dynamics of eDNA in marine environments indicates that eDNA signals are highly localized and may dissipate beyond detection levels within a few hours of production.

The limits of AI for authoritarian control

American Journal of Political Science, EarlyView.
Abstract An emerging literature suggests that artificial intelligence (AI) can greatly enhance autocrats' repressive capabilities. This paper argues that while AI presents a powerful new tool for authoritarian control, its effectiveness is constrained by the very repressive institutions it is designed to serve.

Avoiding erroneous decisions: evidence, population impact and acceptability of universal mental health interventions in schools – a commentary on Andrews et al.

Child and Adolescent Mental Health, EarlyView.
Foulkes and colleagues argue many ‘universal’ interventions to prevent mental health problems are harmful (‘inflating prevalence’ because they raise awareness of mental health problems, encouraging those without such problems to misinterpret everyday concerns as symptoms of mental health disorders, causing avoidance of stressful situations, worsening ...
