Comparison of Seven DNA Metabarcoding Sampling Methods to Assess Diet in a Large Avian Predator

Environmental DNA
DNA metabarcoding is a rapidly advancing tool for diet assessment in wildlife ecology. Studies have used a variety of field collection methods to evaluate diet; however, there is a pressing need to understand the differences among sampling methods and ...

From Genes to Greens: How Diet, Climate and Phylogeny Shape Freshwater Turtle Microbiotas

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Gut microbiotas of 234 Australian freshwater turtles vary with diet, climate and evolutionary history. Carnivorous turtles hosted richer, distinct microbial communities compared with omnivores, while climate zones shaped phylum‐level patterns. Ecological factors dominated over phylogeny, highlighting the importance of integrating microbiome and dietary

Using Ongoing Wildlife Surveillance Programs to Monitor Antibiotic Resistant Bacteria in the Environment

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Screening of ESBL‐, pAmpC‐ and carbapenemase‐producing Escherichia coli among Swedish wildlife demonstrated a low occurrence of antibiotic resistance in wild animals. Only two ESBL/pAmpC‐producers were detected in red foxes originating from highly populated areas.

Ecological implications and lessons from high pathogenicity avian influenza H5N1 2.3.4.4b in Antarctica

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
HPAI H5N1 was confirmed in 22 South Polar Skuas and one Kelp Gull on Dismal and Horseshoe Islands, Marguerite Bay, Western Antarctic Peninsula in early 2025, with high mortalities consistent with global trends. Rapid antigen tests showed 90% agreement with rRT‐PCR, supporting their utility for early detection in remote environments.

Ecology of Low Pathogenicity Avian Influenza Virus H7 in Wild Birds in South‐Eastern Australia Prior to Emergence of High Pathogenicity Avian Influenza H7 in Poultry

Influenza and Other Respiratory Viruses, Volume 20, Issue 7, July 2026.
ABSTRACT Background Adding to the global burden of high pathogenicity avian influenza (HPAI) H5N1, five HPAI H7 outbreaks occurred globally in 2024. Of these, three occurred in South‐East Australia, with the independent emergence of HPAI H7N9, H7N8 and H7N3, resulting in the destruction of 2 million poultry.
