Dams can landlock populations of amphidromous fishes that formerly migrated between rivers and seas. However, the genetic consequences of these life‐cycle changes remain unclear. Rhinogobius is a speciose genus of freshwater gobies widely distributed in Asia, including non‐migratory R. duospilus and facultatively amphidromous R. similis . Using genome‐wide SNPs from Hong Kong, southern China, we compared the genetic diversity...

Periodical cicada ( Magicicada spp.) ranges have continued to decline even as their habitat has rebounded from historic lows. This counterintuitive trajectory may be a consequence of Magicicada 's limited dispersal capabilities combined with their requirement that individual host trees survive across decades. Indeed, we find that the presence of Magicicada breeding populations is best predicted by tree cover in 1930, not by pr...

Evidence of benefit for pancreatic ductal adenocarcinoma (PDAC) surveillance is accumulating, including earlier staging, extended survival, and improved psychological function. This study aimed to assess the 5-year psychological impact of high-risk PDAC surveillance, performed at St Vincent’s Hospital, Sydney, Australia. Participants were offered annual endoscopic ultrasound (EUS) or magnetic resonance imaging (MRI), with freq...

Objectives Physical activity is associated with reduced risk of prostate cancer (PCa) progression and death; changes in insulin sensitivity and inflammation are potential mediating mechanisms. This study examined whether exercise after PCa diagnosis affects insulin-related and inflammatory biomarkers. Methods The Active Surveillance Exercise (ASX) randomized controlled trial was assigned to men undergoing active surveillance f...

We document a unique dorsal protrusion of a southern eagle ray ( Myliobatis tenuicaudatus ) by‐caught in a trawler off the coast of New South Wales, Australia. Radiological imaging led us to conclude the abnormality is a congenital defect that resulted in a pair of additional pelvic fins growing on the dorsal surface. It is unlikely the abnormality had substantial impact on the growth and survival of the animal since it had gr...

Environmental change is increasing vulnerability for many local communities worldwide. This can affect social, health, economic, environmental and cultural values, and challenges our ability to achieve Sustainable Development Goals. Previous research has quantified such community vulnerability using indices such as the Livelihood Vulnerability Index (LVI) and the Livelihood Vulnerability Index-Intergovernmental Panel on Climat...
