**AQOB celebrates five years' on 2SER this week** Many heartfelt thanks to all the wonderful, enthusiastic, wise and informed guests who have freely given their time to appear on AQOB and provide material for the website. That's community for you! Join Mark O'Connor for more myths and misinformation about population management in Australia. And then out to the backyard (or even balcony) with Costa Georgiadis and learn about aquaponics.

Two stories about managing populations today, One's about flying fox camps. Apparently this can be difficult but no where near the problems associated with Australia's people population.

On the program today: A very thirsty Coorong wetland - five years without a drop of water from the Murray! And popular myths about Australia’s population predicament.

Frogs may like water but even they can have too much - what happens to them in a flood? For Sydney's Botanic Gardens, trees and flying foxes have become a heated issue (and a court case). How dangerous ARE our sharks? Does it depend on being in the wrong place at the wrong time?

Diving with sharks – an experience that is becoming increasingly sought after, it has many positive benefits for people’s attitudes to sharks and their preservation. Environmentally friendly fruit fly research. Dr Marianne Frommer describes some fascinating Australian research into fruit fly control.

Dams, coal, agriculture and water - and then there’s the environment too… NSW seems to have a few problems with sustainable, long term management of natural resources. Guests on the program discuss different areas of concern. Leigh Martin reviews first the disappointingly poor progress for the return of flows to the Snowy River and then the disturbing likelihood of the spawning of an additional very expensive white elephant – Hunter Water’s proposed Tilliga dam. Dr Ann Young examines further Hunter Valley environmental problems with the impact of both open cut and long wall tunnel coal mining on the region’s rivers and streams and quality agricultural land.

You can grow far more in a garden than plants. Costa Georgiadis sows the seeds of colour, movement and FUN – elements that will grow any season of the year. The Common myna (AKA Indian mynah) is here to stay it seems. Darryl Jones and colleagues at Griffith University believe that studying the birds’ roosting colonies is essential to determine the effectiveness of any control strategies.

The horned turtle has been long extinct, known only through ancient fossil records so imagine the thrill of excavating midden packed with actual bones less than 3000 years old. Still extinct but this time the cause is obvious. What’s happening to ENSO? El Niño has been a great shaper of Australia’s predictable patterns of droughts and flooding rains and for example, of the behavioural adaptations of Australian wildlife. But now weather patterns are changing dramatically as a result of our rapid climate changes.
