Seminar: Marsupial decline following fox control. What an Reindeer tell us

Speaker: Dr Nick Dexter

Location: 11:30 am to 12:30 pm in Building 6, Level C, Room 12, University of Canberra

Fox control programs have resulted in the recovery many Australian mammal species threatened with extinction. However, these increases have often been followed by crashes in abundance. Reasons suggested for these crashes include; meso-predator release and disease. Using simple population models  and evidence from eruptive ungulate populations we suggest that these crashes are to be expected and are due to the increasing population overshooting carrying capacity. We also predict that the timing of the decline will be dependent on the species

Emissions of methyl-halide and -thiol compounds from plants: Biological significance and metabolic regulation.

Biogenic emissions constitute the predominant source of chloromethane in the atmosphere and thus influence the integrity of ozone layer. Biosynthesis of this gas is also a suspected Cl– detoxification mechanism among organisms in saline habitats. Our attempts to dissect this metabolic pathway led to the discovery of a novel class of plant enzymes – thiol methyltransferases (TMTs) – and the genes encoding these, which can methylate halides

Developing Management Techniques Specific to Controlling Little Fire Ants (Wasmannia auropunctata Roger) in Various Ecological Habitats.

Speaker: Michelle Montgomery

Location: 11:30 am to 12:30 pm in Building 6, Level C, Room 12

Electric Ants (Wasmannia auropunctata Roger) are one of five ants on the IUCN-ISSG’s “world’s worst invasive species” list and are widespread throughout the Pacific. Past research on this species focused on impacts to native ecosystems but little has been done on effective control methods. Traditional control efforts using baits and insecticidal sprays have had limited success for various reasons and the pest continues to spread impacting residents, agriculture, and forest ecosystems.
