Nitrite (NO 2 − ) is a key denitrification intermediate, formed from nitrate (NO 3 − ). Transient NO 2 − accumulation varies among denitrifiers, yet the underlying causes remain poorly understood, despite its potential toxicity and role in NO and N 2 O emissions. We profiled 18 related Stutzerimonas strains, including the model Stutzerimonas perfectomarina ZoBell, and identified three phenotypic clusters (full, partial and low...

Aim After environmental disasters, species with large population losses may need urgent protection to prevent extinction and support recovery. Following the 2019–2020 Australian megafires, we estimated population losses and recovery in fire‐affected fauna, to inform conservation status assessments and management. Location Temperate and subtropical Australia. Time period 2019–2030 and beyond. Major taxa Australian terrestrial a...

Otosclerosis is a bone disorder of the otic capsule and common form of late-onset hearing impairment. Considered a complex disease, little is known about its pathogenesis. Over the past 20 years, ten autosomal dominant loci ( OTSC1-10 ) have been mapped but no genes identified. Herein, we map a new OTSC locus to a 9.96 Mb region within the FOX gene cluster on 16q24.1 and identify a 15 bp coding deletion in Forkhead Box L1 co-s...

Breeding systems vary widely in birds, from monogamous pairs through to complex group systems where subordinates assist breeding individuals to rear young each season. The Australian magpie varies geographically both in plumage patterns and social organization. Some populations of both eastern and western plumage forms are plural breeders with group size varying from three to over 15 mature individuals. This study used variati...

Pancreas disease (PD) is a serious disease of farmed Atlantic salmon, Salmo salar L . It was first described in Scotland in 1976 and has subsequently been found in Ireland, Norway and North America. The disease primarily affects Atlantic salmon smolts during their first year at sea and losses can be as high as 50% of the yearly smolt input, but more recently it has become more common in one sea winter fish. Although there have...
