Australian Moths and Butterflies Are Barcoded

Australian moths and butterflies are being barcoded. There are 10,000 species in Australia and 65 per cent of them have been coded, 28,000 specimens in all. They are not flying around with a tag on them. DNA is analyzed then recorded with an image of a specimen in a barcode system.

The database is a combined project by the Atlas of Living Australia (ALA) and CSIRO's Australian National Insect Collection (ANIC). It is the first time such a system has been used to categorize a group of insects in a country. This is the beginning. Plans are in train to record most organisms worldwide.

The technology has been used to determine if wrongly named fish are being sold. It will be used to identify dangerous pests coming into Australia. Species will now be more effectively categorised in research.

New Jellyfish in Coffs Harbour

It seems humans know just about everything. This is a myth really. A new species of jellyfish has be seen in Coffs Harbour, NSW. It seems the marine creature has been there for a long time.

The mystery "object" is a box jellyfish that appears to be totally harmless. It is unlike the Irujandji and is smaller than the dangerous Chironex flecker box jellyfish. Fishermen have been seeing the new jellyfish for sometime but authorities took no notice. A game crew took photos of the animal last week.

Finally "professionals" acted and arrangements are being made to catch some specimens. Fish of all kinds are moving south as the temperature of the ocean increases due to climate change. It is believed the visiting jellyfish come from more northern climes. Usually jellyfish do not move south because they can be harmed by rougher seas. They prefer the warm, calmer tropics.

If Fishing Is Not Reduced There Will Be Little to Sell

Consumers will have to learn to do without. If we want our children to enjoy seafood we will have to eat less of it now. That means paying a higher price.

A guide has been put out by the Australian Conservation Society to make people aware of what species are in danger. This Christmas consumers have bought lobster, bugs and mackerel. It is debatable as to whether all of these are actually threatened.

Not everyone is in favor of informing the general public about the need for change in the seafood industry. The Queensland Seafood Industry Association, in particular retailers the body represents, are angry because they fear a fall in income. They are saying the industry is already struggling. Yes, it is struggling because seafood is becoming more difficult to supply.

It is really a case of "someone has to pay and it won't be us". They say fishing boats have been bought and licensing fees have been paid. The reality is, however, that if fishing is not cut back there will not be much to sell.

Ocean Dead Zones Could Cause Mass Extinction

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 deemed to be a contributing factor to dead zones. Man changes the balance of life.

Things Falling From the Sky

Things have been falling from the sky for hundreds of years with no solid explanation. It has been claimed that marble pillars from ancient Rome fell gently to earth a century or so ago. This is deemed to be just a story, but Frogs, fish, worms and squid being dumped onto the earth during rainstorms is fact.

The main theory is that they were picked up from small shallow ponds by whirlwinds. This is just theory and has not be proven. Indeed, no one has observed actual "pick up" occurring. When a fall has taken place more of the same can be expected. The species of frogs and fish are not always local. They are from different climes than the dumping location. Such passengers of storm have one thing in common: they are generally small.

Although stories of small creatures falling with rain are usually much the same, some cases are truly extraordinary. Fish fell from the sky during a Singaporean earthquake in 1861. Leonard Bourne was running in a rainstorm in 1966 in Australia when a large fish hit him on the shoulder.

The explanation of pick up has one major flaw: Why are creatures of only one species selected with no pond debris? Furthermore, the dumped animals are always alive so the move from one area to another must have been short.

Cutting Out Fat to Lose Weight Results in Osteoporosis

Being overweight leads to heart disease but it can also cause osteoporosis. This is due to people cutting out vital elements in the diet in their attempts to lose weight. Dairy products are essential for strong bones. Yet milk, butter and cheese are precisely what it being disregarded in diet by 30 per cent of women. Another danger is the consumption of bread. An astounding 40 per cent of women have stopped eating this food that is calcium fortified.

Research has shown that the real cause of weight gain is carbohydrates. Yes, it's as simple as that. People who only cut out sugar lose weight very quickly and maintain a low body weight thereafter. People concentrate on eating low fat diets. Even though research shows this to be the wrong thing to do. Look at movies made up to WWII. Actors and actresses and especially the extras were all quite skinny then. In those days most Western nations had not developed the high sugar habit. And most workers then went to work on a large fatty fried breakfast.

Danger in the future will not be with low fat diets. Young people today just refuse to eat vegetables. Cabbage and broccoli are high in iron. Young people steer well clear of these. Hope lies with the intake of fish. The young do like fish. Note the dash for seafood at Christmas. Fish contains calcium and minerals. Processed food is high in sugar. Government needs to have a policy aimed at lowering sugar intake in our diets.
