1. Myrtaceae familyMyrtaceae, also known as the Myrtle family; they are known for their high adaptability and survival rate in harsh Australian environments, allowing them to survive in a variety of ecological conditions. The family ranges from tall trees to medium-sized shrubs and is found in tropical and subtropical environments, although it can be found growing in desert-like conditions due to the nutrient-poor soil found on coastal lines. It is also known for the high abundance of fragrant oils it produces (David V. Beardsell. Etal, 1993).2. The characteristics of this family typically resemble the harsh conditions that the Australian environment offers to plants. Tall Myrtaceae trees are covered in smooth bark, which sheds annually to protect fire-sensitive areas. The surface of the leaf has tiny dots called sebaceous glands and the flowers form in clusters. Research has also shown that they also have multiple stems emerging from the surface. These stems appear to be novel adaptation measures against their high fire risk habitats (Peter G. Wilson, 2011). Some species of the Myrtaceae family found in rainforest habitats are generally broad and mesophyllous, with the presence of sharp tips as a leaf morphology; while species from arid or coastal regions often have smaller, narrower leaves that sometimes have a scale-like feel, while retaining simple, non-vascularized leaves, with adaptations to serrated protrusions (Peter G. Wilson, 2011). The flowering of this family varies due to providing a barrier to interspecific hybridization factors, through; numerous species of the family in the same locality usually flower at the same time each year (David V. Beardsell. Etal, 1993). Due to the high abundance of wildlife in Au...... middle of paper...... animals will not survive. If eucalypt species became extinct, koala species would be endangered (JD Majer. Etal, 1992).4.3 Importance to ecosystemsThe center of many Australian ecosystems is eucalyptus as there are numerous organisms whose lifestyles interact with plants that provide food sources, shelter and nesting sites. Eucalyptus species are present throughout much of the Australian continent due to its adaptability and morphology aspects. These species found on the coasts, their roots provide stable soil as the sand is very aerated and can move incredibly. With the presence of the species' strong and long roots, this allows the soil to be secure and resilient whereas if you remove the plants from this environment, the sand on the beaches will erode away due to the lack of stability (David V. Beardsell. Etale, 1993).
