Environmental DNA (eDNA) Quantitative Polymerase Chain Reaction‐Based Assays for Surveying 125 Taxa of Importance to North America

Environmental DNA, Volume 7, Issue 3, May–June 2025.
We present 125 eDNA quantitative real‐time polymerase chain reaction (qPCR) assays against animal species of importance to North America. We show how these assays were designed and validated to comply with the Canadian national eDNA standards to allow confident eDNA detection for coastal and inland ecological surveys and biosurveillance.

Research on the Prediction Method of 3D Surface Deformation in Filling Mining Based on InSAR‐IPIM

Energy Science &Engineering, Volume 13, Issue 5, Page 2401-2414, May 2025.
Aiming at a series of defects existing in the monitoring of mining area by InSAR technology, this paper proposes an insar‐ipim model to predict the three‐dimensional surface deformation of filling mining. The parameters of the model are inversed by using the group optimization algorithm slime bacteria algorithm proposed in 2020, and the empirical ...
