    A comparison of electronic and manual fracture risk assessment tools in screening elderly male US veterans at risk for osteoporosis

    This study compares four screening tools in their ability to predict osteoporosis. We found that there was no significant difference between the tools. These results provide support for the use of automated sc...

    Evolution of corallivory in the gastropod genus Drupella

    Although muricid gastropods in the genus Drupella are well-known consumers of Indo-Pacific corals, their evolutionary and ecological history is unclear, as is their relationship to the apparently facultative cora...

    Identification of the primary caspase 3 cleavage site in alpha II-spectrin during apoptosis

    Alpha II-spectrin is one of the major proteins responsible for maintaining the cytoskeletal integrity of the cell. The caspase 3-mediated cleavage of alpha II-spectrin during apoptotic cell death may play an i...

    Species boundaries in the starfish genus Linckia

     The genetic basis for species boundaries in the starfish genus Linckia was examined using variation observed in 613 base pairs (bp) of sequence from the cytochrome oxidase I gene of mtDNA and 16 allozyme loci. F...

    Phylogenetic relationships among giant clam species (Mollusca: Tridacnidae) determined by protein electrophoresis

    Analyses of allozyme variation at 26 loci in eight species of giant clams, collected from the Western Pacific between 1989 and 1991, have confirmed the major grou**s currently recognised within the family T...

    Genetic uniformity of widely separated populations of the coral reef starfishLinckia laevigata from the East Indian and West Pacific Oceans, revealed by allozyme electrophoresis

    Gene flow among 18 widely separated populations of the starfishLinckia laevigata was investigated using allozyme electrophoresis at seven polymorphic enzyme loci. Little genetic differentiation was observed among...

    Gene flow among giant clam (Tridacna gigas) populations in Pacific does not parallel ocean circulation

    Tridacna gigas (L.) populations were sampled from 13 locations throughout the west Pacific in 1990–1991 and screened for allozyme variation at seven polymorphic loci. Significant genetic differences were found b...

    Genetic consequences of long larval life in the starfish Linckia laevigata (Echinodermata: Asteroidea) on the Great Barrier Reef

    Gene flow between populations of the asteroid Linckia laevigata (Linnaeus) was investigated by examining over 1000 individuals collected from ten reefs throughout the Great Barrier Reef (GBR), Australia, for gene...

    No genetic differentiation of giant clam (Tridacna gigas) populations in the Great Barrier Reef, Australia

    Six Tridacna gigas populations were sampled in 1990 from locations throughout the central and northern Great Barrier Reef (GBR). Despite separations in excess of 1000 km, mean Nei's unbiased genetic distances amo...

    Genetic structure of giant clam (Tridacna derasa) populations from reefs in the Indo-Pacific

    Large genetic differences were observed among the Great Barrier Reef (GBR), Fiji and Philippine populations of Tridacna derasa (Roding) sampled in 1989 and 1990 (Nei's unbiased genetic distance, D,=0.137 to 0.341...

    Scanning electron microscope studies of pollen behaviour on immature and mature brussels sprout (Brassica oleracea var. Gemmifera) stigmas

    Observations of pollen tube behaviour on the stigma surface have shown that germination and growth of compatible pollen tubes is unaffected by stigma age. However, incompatible pollen tubes fail to become atta...
