This study shows spiders can effectively sample arthropod DNA from their gut contents, revealing community diversity and biotic interactions comparable to traditional methods and preserving historical data up to 20 years.

The paper compares DNA extraction workflows for leaf-litter eDNA metabarcoding, finding that recovery and reproducibility depend on workflow and marker, with site-level ecological signals retained across methods.

This study compares bulk DNA metabarcoding and environmental DNA (eDNA) methods for assessing arthropod diversity in three Guam habitats, finding both methods detect significant taxa with eDNA offering a non-destructive alternative.

The paper examines beetle-pathogen interactions in Hawaii's Rapid 'Ohi'a Death, identifying key invasive species as disease vectors and highlighting the role of symbiosis in disease spread.

The paper uses leaf-derived eDNA to study arthropod community structure and invasion dynamics on Oahu, Hawaii, revealing elevation-based transitions and plant species effects.
