Dead fish on South Australian beaches gives bad conservation image. When marine animals wash up on the shore dead what does a state government do about it? It tries do deny it and cover it up! Maybe it will stop in time - unfortunately it continues. The thousands of small fish dead on the beaches are bad enough, but dolphin corpses are found as well, even some penguins. The location is on the South Australian coast near the Port River, Adelaide.  Recently, a grieving female dolphin was seen nuzzling her dead baby, a terrible sight. A concerned PHD student, Nikki Zanardo, is investigating the issue. There is a worrying mystery here. Why has the state government sent dolphin samples to New Zealand? Tests could have been done in South Australia. If herbicides or industry poisoning is at fault, it will all come out eventually. You cannot hide anything today. It is not right that consumers are allowed to eat seafood when there is a possibility that dangerous biologic...

Who would have thought that ear wax would add to scientific knowledge. A wax ear plug from a dead 12 years old whale has shed more light on its life. Traditional research involved blubber, faeces and blood. Lipids, keratin and waxes built up by two layers a year. This was used to tell the age of the whale. When sliced ultrafine, 24 separate rings were identified. Closer analysis was done and various industrial chemicals and pesticides were found. Some of the chemicals persisted in the wax despite being banned world wide ten years before. There is no doubt that these chemicals were stored in the females fat and passed onto the young. Mercury was high at two periods in the whale"s life. Testosterone level rose when the whale reached maturity at ten years of age. The high chemical rate is believed to have an indirect effect on the high cortisol level, the stress hormone. However, a 12 year old male would have been driven to compete with other males for females and form so...

The number of oceanic dead zones in the world is increasing. In the zones oxygen levels are too low to sustain life. It is widely know that a monster area in the south Atlantic is growing in size, but there are hundreds more smaller dead zones. They are caused by overfishing and the nutrient rich residue in fertilizer runoff. Climate change also plays a part. As oceans warm up layers form and some become stagnant with low oxygen levels. Long standing currents and wind directions have changed which has reduced layer intermixing. Since 2000 over 400 dead zones have been identified. In the 1980s there were little more than a hundred. Some are huge, more than 70,00 sq kilometers, while many are less than a square kilometer. The lack of oxygen not only causes death. Offspring are born deformed. They do not survive, or produce fewer young. Danger of a mass extinction is now very high. Dead zones are forming on continental shelves where most fishing is done. The mere presence of humans is dee...
