Gloomy Octopus Moves to Tasmanian Waters - Marine Science Study

The common Sydney octopus does not look like a happy chappy, but he always looks gloomy. It is just the way he is. Not doing so well in the sea around New South Wales he has moved down to the cooler waters off Tasmania. Because they increased in number from a few early arrivals their genetic diversity is less than those on the east coast. More are arriving from NSW and Victoria so things are improving. The exodus began in the mid-2000s. A joint project between James Cook University, the Centre for Marine Socioecology (CMS) at the University of Tasmania and the Institute for Marine and Antarctic Studies (IMAS) is researching the genetics of the species. Gloomy octopuses have been found as far south as the waters near Hobart. A new study, published in the journal Scientific Reports, suggests the species is thriving in Tasmanian waters with a healthy mix of genes from local and interstate populations. The species, also referred to as the common Sydney octopus, or octopus ...

Over 50,000 Years Ago People Knew How get to Australia

According to new research humans purposefully set out to reach Australia. It seems scientists can read minds now - what a great leap forward! Seriously though, knowing what individuals are thinking is an impossible thing to do, largely because people perceive settings differently. No two people are exactly alike not even twins. Perception is a function of consciousness as perceived through the senses which differs for everyone. Sea levels were lower in 65,000 BP, so islands off the coast of northern Australia could be seen from high points on islands off Indonesia. There is a problem here, however, in that there are major racial differences between Australian Aboriginals and Indonesians. Surely, some dark skinned inhabitants of the South East Asian archipelago would have remained and interbred with "typical" Asians we see today. Note, Papua New Guineans are different than Australian "natives". To say that an assembly of about 100 boats were organized...

Mercury From Northern Hemisphere Pollutes Australia

Mercury pollutes both the northern and southern hemisphere. The Australian tropical zone is polluted. ◘1 northern up we mercury at am it aged mercury news mercury an northern ◘1 Australia is getting mercury pollution from the northern hemisphere. Most of the deadly metal stays in the air over the top half of the planet.
