Using fecal DNA metabarcoding to investigate the animal diet of black rails, yellow rails, and soras
Wildlife Society Bulletin, Volume 49, Issue 3, September 2025.We used fecal DNA metabarcoding to investigate the diet of yellow rails, Eastern black rails, and sora during the non‐breeding season. Arthropods, particularly ants, were prevalent in their diets, suggesting possible interactions with invasive red imported fire ants.

Occurrence characteristics of microplastics in Dongting Lake, China
River, Volume 4, Issue 3, Page 363-374, August 2025.Abstract Lakes are critical sinks for terrigenous microplastics (MPs), yet understanding their ecological risks remains hindered by data uncertainties and the absence of local background values. In this study, an enhanced pollution load index (PLI) model integrating stochastic mathematical methods and species sensitivity distributions (SSD) was ...

Cross‐Validation of Diet Determination Methods for Seabird Conservation
Environmental DNA, Volume 7, Issue 4, July–August 2025.This study on the diet of the endangered New Zealand king shag (Leucocarbo carunculatus) compared the frequency of occurrence of fishes detected from the same regurgitated pellets (n = 191) using both hard parts and DNA metabarcoding methodologies.

Impact of CO2‐Induced Aquatic Acidification on Environmental DNA and RNA Shedding and Persistence
Environmental DNA, Volume 7, Issue 4, July–August 2025.We conducted mesocosm experiments to determine the shedding and decay rate constants of eDNA and eRNA in Pacific oysters (Crassostrea gigas) at various partial CO2 pressures in seawater. To our knowledge, this is the first study manipulating seawater pH using CO2.

Molecular phylogenetic analyses support the monophyly of Hexapoda and suggest the paraphyly of Entognatha [PDF]
, 2013 BackgroundMolecular phylogenetic analyses have revealed that Hexapoda and Crustacea form a common clade (the Pancrustacea), which is now widely accepted among zoologists; however, the origin of Hexapoda remains unresolved.
