The Australian pygopodid lizard genus Delma is characterised by morphologically conservative but genetically divergent lineages and species. An initial assessment of molecular and morphological variation in Delma australis Kluge, 1974 throughout its main distribution in Western and South Australia reveals at least two undescribed species that are presently included under this epithet. Here we d...

This study investigates the comparative hepatoprotective activity of crude ethanol extracts of Cuscuta australis against acetaminophen (APAP) intoxication. Thirty-six rats were randomly divided into six groups of 6 replicates: Group 1 which served as control received water. Group 2 was orally administered 835 mg/kg body wt. of paracetamol on day 8. Groups 3 and 4 were orally administered ethano...

Using controlled experiments, the ability of the trematode parasite Stegodexamene anguillae, encysted within its intermediate fish host, the common bully Gobiomorphus cotidianus, was tested to indirectly detect the presence of its definitive host by exposing infected G. cotidianus to chemical cues from the definitive host, the short-finned eel Anguilla australis. The trematode can abbreviate it...

The impact of gnawing by Microcavia australis on the survival of Geoffroea decorticans plants was studied in the Monte Desert of Argentina. Sampled ( ) plants N s 105 were selected randomly from two different colonies of M. australis. For each plant sampled the following properties were measured: the diameter of the trunk at ground level; the distance to the nearest burrow of M. australis; the ...

Alstroemeria L., one of the most diverse genera of the Chilean flora and of high floricultural value, is represented by 35 species, most of them distributed between 28-38° S in the Mediterranean zone of Central Chile. There are 24 complex-forming taxa, of which 18 have conservation problems (8 are considered "endangered" and 10 as "vulnerable"). One of these complexes is Alstroemeria presliana ...

Title of Document: A COMPETITIVE INTERACTION AND DOMINANCE EXPERIMENT BETWEEN THE VEGETATIVE MARSH SPECIES PHRAGMITES AUSTRALIS AND SPARTINA CYNOSUROIDES UNDER ELEVATED NITROGEN AND SALINITY LEVELS Michelle L. Arthur, Master of Science, 2013 Directed By: Dr. Andrew Baldwin, Department of Environmental Science and Technology In recent decades the invasive plant Phragmites australis (common reed)...

Disturbances are a primary facilitator of the growth and spread of invasive species. However, the effects of large-scale disturbances, such as hurricanes and tropical storms, on the broad geographic patterns of invasive species growth and spread have not been investigated. We used historical aerial imagery to determine the growth rate of invasive Phragmites australis patches in wetlands along t...

The response and adaptation to drought remains poorly understood for Paulownia australis. To investigate this issue, transcriptome profiling of four P. australis accessions (two diploid and the other two autotetraploid) under water stress condition were studied using Illumina Genome Analyzer IIx analysis. The current study aimed to identify genes of P. australis metabolism pathways that might b...

AT PRESENT five species are known in the genus Rb odopeltis, which belongs to the red algal order, Cryptonemiales. Of these, Rbodopeltis anstralis was first found in Australia, and the other four species, R. borealis, R. setchelliae, R. liagoroides, and R. gracilis all grow in the southern islands of Japan and were described by Yamada. The first description of a species of the genus Rh odopelti...

Cytotoxic T-lymphocyte (CTL) activity developed against the major infected target cells of rickettsial infections, endothelial cells and macrophages. Spleen cells from mice immune to Rickettsia conorii exerted specific major histocompatibility complex (MHC) class I-matched CTL activity against R. conorii-infected SVEC-10 endothelial cells, with peak activity on day 10. Similarly, spleen cells f...
