Figs Print E-mail
The 'Figs' are contained in the genus Ficus of about 1000 different species found worldwide, including as potted plants in many households. They are of one of the best known and widespread of all plant genera. It is not just the distribution that attracts interest, however, for the genus has some important and fascinating ecology.

Many start off as mere epiphytes, with the 'strangler' forms of many species having their fruits deposited in the top of a canopy by a fig eating animal, and growing their roots down around a host tree. Some species of figs in the Australian rainforests have evolved the unusual habits of 'ramiflory' and 'cauliflory', the fruiting on the branches and the main trunk respectively.

They do not have flowers in the traditional sense, for the tiny reproductive parts are hidden inside round receptacles that we normally recognize as the fruit. Figs have a highly specific and reliant relationship with 'fig wasps' (family Agaonidae); the plant relies on the wasps for pollination, while the wasps rely on receptacle to reproduce. These tiny flowers of each particular species of fig are pollinated only by another particular species of 'fig wasp' (family Agaonidae). The plant relies on the wasps for pollination, while the wasps rely on the 'fruit' to reproduce within.  Because of this relationship, it is thought figs have to provide these fruit receptacles more or less continuously, and thus many figs fruit asynchronously. That is, trees fruit out of sync with other individuals of the same species.

Plants

Fungi
Fungi actually belong to a completely different kingdom from the animals and the plants and are not particularly related to either. There are thought to be about 250,000 species of fungi in Australia, and thus they far outnumber the regular vascular plants but most of these species are too small to be noticed.

Birds

Grebes
Grebes are an unusual group of birds that constitute their own order. Some of the larger grebes are well known for their spectacular mirror courtship displays, amongst much water splashing. The smaller grebes, often known as 'dabchicks' resemble baby ducks. Grebes are rarely observed on land. They even tend to nest on the water, often within reed beds. Individuals of some species may spend their entire life cycle on one lake. When underwater hunting for their prey, they propel themselves with their feet, not their wings.

Dogs
The first animal to be deliberately introduced to Australia by humans was probably the dingo. This 'Australian Native Dog' is, despite common misconceptions, like all breeds of domestic dogs, merely a type of the Grey Wolf,Canis lupus.
