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...
Grant-Making Criteria for Developing Useful and Usable Marine Science: A Philanthropic PerspectiveOA Marine
Decades of scholarship and practice highlight the need for scientific research that informs individuals on the front lines of decision-making. Funding organizations can play an important role in supporting useful and usable research by discussing the criteria and processes they use to guide the development and review of funded projects. However, practical examples of how funders can engage with grantees on the design of resear...
This investigation sought to determine whether post-exercise cold water immersion and low glycogen availability, separately and in combination, would preferentially activate either the Exon 1a or Exon 1b Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) promoter. Through a reanalysis of sample design, we identified that the systemic cold-induced augmentation of total PGC-1α gene expression observed...
Recruitment and growth of two small‐bodied resident fish species (Gobiidae and Atherinidae) in oligohaline, seasonally open lagoonsNARA Subscribed
Spatio‐temporal recruitment patterns, growth and survival of the Swan River goby Pseudogobius olorum and western hardyhead Leptatherina wallacei are described from two small, coastal lagoons on the south coast of Western Australia. In these lagoons, estuarine salinity dynamics were relatively stable over much of the autumn–spring period when freshwater inputs from rivers were reduced and there was no oceanic connection. Prefle...
Diversity of hopanoids and squalene‐hopene cyclases across a tropical land‐sea gradientNARA Subscribed
Summary Bacterial hopanoids are ubiquitous in Earth surface environments. They hold promise as environmental and ecological biomarkers, if the phylogeny and physiological drivers of hopanoid biosynthesis can be linked with the distribution of hopanoids observed across a breadth of samples. Here we survey the diversity of hopanoid cyclases from a land‐sea gradient across the island of San Salvador, in the easternmost part of th...
Cryptic estuarine gobiid fish larvae (Pisces: Gobiidae) identified as Pseudogobius olorum using allozyme markersNARA Subscribed
Allozyme electrophoresis was used to identify cryptic larvae of potentially four sympatric south‐western Australian estuarine gobiid species: Afurcagobius suppositus , Arenigobius bifrenatus , Favonigobius lateralis and Pseudogobius olorum . Genotypes of six diagnostic loci expressed in 46 unidentified larval gobiids indicated that they were unambiguously P. olorum .
Descriptions and illustrations of stages in the larval development of two common sympatric freshwater fishes in streams of tropical north‐east Queensland, the fly‐specked hardyhead Craterocephalus stercusmuscarum stercusmuscarum and the purple‐spotted gudgeon Mogurnda adspersa are presented. Larval development is described in terms of ontogenetic changes in gross morphology, notochord morphology, pigmentation, finfold morpholo...
Early ontogeny of coal grunter from hormone‐induced spawnings and laboratory‐reared embryos and larvaeNARA Subscribed
Spawning of coal grunter Hephaestus carbo was successfully induced using doses of human chorionic gonadotrophin (hCG) between 500 and 3000 IU kg (body weight) −1 . Water hardened eggs are telolecithal, amber in colour, spherical, transparent, demersal and slightly adhesive with a single large oil droplet and perivitelline space 47% of total egg volume. Cleavage begins 10–15 min after fertilization. Epiboly begins 6h after fert...
