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.

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

Comparative Analysis of Environmental DNA Metabarcoding and Spectro-Fluorescence for Phytoplankton Community Assessments [Elektronisk resurs] [PDF]
Quantifications of phytoplankton biomass and species composition are crucial for monitoring biodiversity and population dynamics in aquatic environments, and both direct microscopic counts and fluorescence-based methods have been widely used for ...

Experimental feeding validates nanofluidic array technology for DNA detection of ungulate prey in wolf scats [Elektronisk resurs] [PDF]
, 2023 The study of carnivores' diet is a key component to enhance knowledge on the ecology of predators and their effect on prey populations. Although molecular approaches to detect prey DNA in carnivore scats are improving, the validation of their accuracy, a

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.

Data Structure-Aware Ensemble Modeling for Time-Series Prediction: A Case Study of Sewage Generation
Applied SciencesThis study investigates the influence of time-series data structure on model behavior in sewage generation estimation. Annual data from four regions (2017–2023) were analyzed using Random Forest (RF) and Voting Regressor (VR), while structural ...
