Bull ants do not feed during all daylight hours. Observation has shown that they feed at twilight. When the sun is brighter for longer for example in summer, or there is no cloud cover, bull ants forage for food later in the day. When the sun is darker, earlier, they search for food sooner in the day. It was believed that all insects fed according to circadian rhythms, but this does not seem to be the case. Activity in the nest was affected by cloud cover. Outside activity that involves feeding occurs at twilight. Obviously, they are feeding during these short intervals to avoid predators: most animals that eat ants would be inactive at twilight. Tests were done at ANU in Canberra. Bull ants were put in containers where diffused light was altered. It was found they only fed when the light was set at a particular low level. Evolution does take some winding paths. This shows though that evolution develops in a rational way. http://www.adventure--australia.blogspot.com/ http://www.t...

There must be a dearth of things to study. Scientists are now researching the odd sounds that people make. It may seem weird but its true. Those who can make odd sounds are called beatboxers. Scientists are interested in percussion sounds. These are expressed in Celtic, Chinese, North American and Indian cultures. Hip-hop is an area of great interest. A young "practitioner" had MRI scans done on his mouth while he created percussion sounds. The conclusion reached is that a lot of brainpower is involved in imitating percussion. It "is a small part of the larger puzzle," experts say. In my view it takes little mental concentration. Just put your tongue behind you top teeth a "tap" away. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml http://www.technorati.com/blogs/ . . . . . . . . . . . . . . . . . . . .

Australia is fighting against the spread of red fire ants. This pest has invaded other countries such as the US. Nothing seems to work to stop their malicious takeover. They give a nasty bite. It was thought to be a simple kind of ant but studies have shown it to be a complex creature. It has two distinct variants in its social structure. Normally colonies keep their distance. On the other hand, many colonies do form a supercolony where queens work together and breed in safety. Ants of the supercolony do kill queens of isolated colonies. The ants are different genetically. Queens of individual colonies are fatter. This is to feed the first larvae when they start the colony. Queens who work together never need the "boost" fat. The change of a single gene dramatically changes physicality and behavior. It is contentious as to whether there will be an evolutionary winner. We just do not know at this stage. It is hoped that chemicals producing violent behavior can ...
