Assessing the benefits and risks of translocations in changing environments: a genetic perspective
A classification of translocations based on specific genetic goals for both threatened species and ecological restoration is provided, separating targets based on ‘genetic rescue’ of current population fitness from those focused on maintaining adaptive potential.
Clonality and sexual reproductive failure in remnant populations of Santalum lanceolatum (Santalaceae)
Clonality, genetic isolation and sexual reproductive failure indicate that preservation of each population, and possibly the establishment of new ones, should be objectives of the conservation strategy for the S. lanceolatum remnants.
Divergent levels of genetic variation and ploidy among populations of the rare shrub, Grevillea repens (Proteaceae)
It is proposed that the development of clonality and polyploidy in small or isolated populations may allow persistence but also reduces the effective size of the sexual population.
Connectivity, genetic structure and stress response of Phragmites australis: Issues for restoration in a salinising wetland system
Gene flow appeared regular and widespread between populations of P. australis in the Gippsland Lakes with some local genetic structure and no clear association with salinity, but no genetic evidence of either salt tolerant or introduced variants.
Mycorrhizal specificity of Diuris fragrantissima (Orchidaceae) and persistence in a reintroduced population
This study investigated the diversity and specificity of mycorrhizal fungi associated with five Diuris (Orchidaceae) taxa in south-eastern Australia, as part of a reintroduction program for the
Mutagenesis by the autoxidation of iron with isolated DNA.
The results suggest that DNA damage and mutagenesis brought about by Fe2+ are likely to occur by a Fenton-type mechanism that involves the generation of hydrogen peroxide by the autoxidation of iron and hydroxyl radicals by the interaction of the hydrogenperoxide with Fe2+.
New subspecies of Leionema bilobum (Rutaceae)
Morphological variation in Leionema bilobum (Lindl.) Paul G. Wilson is described taxonomically as four subspecies: viz. subsp. bilobum, which is restricted to the eastern ranges of Grampians National
Detection of endotoxin using an evanescent wave fiber-optic biosensor
The lipopolysaccharide endotoxin is the most powerful immune stimulant known and a causative agent in the clinical syndrome known as sepsis, and this method can be used with other LPS capture molecules such as antibodies, lectins, or antibiotics, to simultaneously detect LPS and to determine the LPS serotype.
Studies on Metatherian Sex Chromosomes VII. Glucose-6-phosphate Dehydrogenase Expression in Tissues and Cultured Fibroblasts of Kangaroos
Expression of the sex-linked enzyme glucose-6-phosphate dehydrogenase (G6PD) was examined electrophoretically in tissues and cultured fibroblasts of female kangaroo heterozygotes ranging in age from
Genomic diversity guides conservation strategies among rare terrestrial orchid species when taxonomy remains uncertain
Genomic diversity identified among the four Diuris species suggests that conservation of this taxonomically complex group will be best served by considering them as one ESU rather than separately aligned with species as currently recognized.
