Socio-ecological challenges and food security in the ‘salad bowl’ of Fiji, Sigatoka ValleyNARA Subscribed
This article examines food security in the Sigatoka Valley, one of the most productive food regions in Fiji, in the context of recent socio-ecological challenges through a case study of Narewa village. Data were collected using semi-structured interviews ( n = 25), a fixed question food insecurity experience survey ( n = 25), and a free listing exercise about preferred and consumed foods ( n = 24). Results revealed that while...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Patterns of rain forest plant endemism in subtropical Australia relate to stable mesic refugia and species dispersal limitationsNARA Subscribed
Aim Our aims were to identify centres of endemism and to infer whether these areas have functioned as refugia for subtropical rain forest plants through historical climate fluctuations. Location Subtropical eastern A ustralia (23–33° S; 145–155° E). Methods We collated 25,000 records of 179 endemic rain forest plants to identify geographical areas with unusually high concentrations of endemic taxa and range‐restricted endemics...
Cell types and structures involved in tench, Tinca tinca (L.), defence mechanisms against a systemic digenean infectionNARA Subscribed
Histopathological and ultrastructural investigations were conducted on 36 tench, Tinca tinca (L.), from Lake Trasimeno (Italy). The gills, intestine, liver, spleen, kidney and heart of 21 individuals were found to harbour an extensive infection of larvae of an unidentified digenean trematode. The eyes, gonads, swim bladder and muscles were uninfected. The parasites in each tissue type were embedded in a granulomatous prolifera...
This study presents an adaptation of current methodologies for preparing mitotic chromosomes from fishes, optimized for use in the field. The high‐quality preparations obtained using this modified methodology is suitable for subsequent chromosomal analysis. Importantly, this method is particularly useful when specimen collection sites are far from research laboratories or when researchers are working with highly sensitive spec...
