This study identifies 217 viruses in New Zealand passerines, finding that social behavior significantly influences virome diversity.

The paper compares viromes of two galaxiid fish with different life-history strategies, finding that the river-resident species has higher viral diversity than the migratory species.

The paper uses metatranscriptomics to analyze PCR-negative SARI samples, identifying microbial transcripts in 43% of cases and highlighting polymicrobial compositions and novel pathogens.

The paper characterizes viral communities in urban waterfowl across New Zealand, finding widespread viral diversity and connectivity despite geographic distance.

The paper identifies a novel divergent porcine adenovirus associated with a disease outbreak in a high-health pig herd, highlighting its potential role in reproductive and neonatal disease.

The paper identifies two divergent coronaviruses in lamprey with reddening syndrome, showing higher viral abundance in diseased individuals.

The paper evaluates four environmental RNA sampling methods for detecting avian influenza viruses in urban waterfowl ponds over a year, finding they detected AIV but with asynchronous results likely due to low viral concentrations.

This study evaluates the GeneXpert II platform for rapid influenza A virus detection in environmental and wildlife samples at a New Zealand seabird colony, demonstrating its feasibility for early warning surveillance.

The paper surveys viruses in New Zealand's introduced mammals, identifying novel species and showing geographic clustering and potential reverse zoonotic transmission.

This study identifies viral communities in New Zealand's aquatic birds, showing that foraging behavior influences viral diversity and reveals novel viruses and mammalian-associated pathogens.

The paper analyzes viral genomic traits across estuarine environments to show how salinity and ecological niches influence viral proliferation and adaptation.

The paper identifies extraintestinal pathogenic Escherichia coli, Enterococcus faecalis, and Streptococcus gallolyticus as potential causative agents of exudative cloacitis in kakapos through metatranscriptomic analysis of lesions and cloacal swabs.

The study sampled wild birds in New Zealand and its territories, finding no HPAI H5N1 but detecting H1N9 in red knots during 2023-2024 migration.

The paper identifies a novel crustavirus, RRLCV, associated with tail fan necrosis in red rock lobsters through metatranscriptomic analysis of uropod and haemolymph samples.

The paper investigates microbial transmission among reef fishes in the Great Barrier Reef, finding limited cross-species transmission despite ecological interactions.

The paper analyzes oral and faecal viromes of New Zealand calves with idiopathic ill-thrift syndrome, finding no novel viruses significantly linked to the syndrome but identifying diverse viral communities.

The paper analyzes viromes of Antarctic fish to compare viral diversity with lower latitude fish, finding comparable complexity and evidence of host-switching and viral adaptation.

The paper compares fully Bayesian and hybrid methods for inferring demographic parameters in bacterial genomic data, finding hybrid methods are computationally efficient and reliable when data have strong temporal structure.
