Red Tailed Black Cockatoo Abstract Calyptorhynchus banksii, or red-tailed black-cockatoo, has coped with extreme variations in its environment. Much like the plant species of Australia, the red-tailed black-cockatoo has evolved physiological and anatomical adaptations that have allowed it to survive in changing surroundings. One of the most prevalent adaptations was that seen in the beak apparatus. Changes in the beak allowed the cockatoos to consume the newly evolved sources of food. The
Adaptations An adaptation is the characteristic of an organism that makes it likely to survive. There are three types of adaptations: structural, physiological, and behavioural. Structural adaptations are physical features, physiological adaptations are related to the internal body functions, while behavioural adaptations refer to how organisms respond to stimuli (Beavis 2014). This paper will discuss some adaptations that help koalas and eucalyptus trees survive in their environments. Part One:
Diversity and Distribution of Eucalyptus Eucalyptus is a genus of hardwood evergreen forest trees, and is the most conspicuous element of Australian vegetation. Its members constitute 95 percent of the continent's forests and are the dominant trees of Australia's woodlands (Kelly 1969). It is an extremely diverse group, with approximately 500 named species and subspecies and nearly 200 described hybrid varieties (Blakely 1965). The genus is overwhelmingly endemic to the Australian mainland and
