Species had introduced to Australia by human since 1788. When a foreign species had successfully out-compete native organisms for food and habitat‚ it may survive and reproduce. However this species can become invasive when there is an excessive increase of population which can cause enormous damage to the ecosystem. The impacts of the foreign species could be immense‚ insidious and irreversible. In Australia‚ invasive species have been recognized one of the most serious threats to biodiversity

and go through a refractory period. During this time the neuron is incapable of producing another action potential (Stillman‚ 2005). In this lab‚ compound action potentials (CAPs) will be measured from an isolated sciatic nerve from a cane toad‚ Bufo marinus. Compound action potentials are the total sum of action potentials from the multitude of neurons that compose a nerve (Stillman‚ 2005).

The focus of the investigation explored the fundamental properties of cardiac muscle on a cane toad’s (Bufo marinus) heart and the adaptive ability of the heart to produce a response when subject to different conditions of temperature‚ stretch on contractile force‚ substances of acetylcholine‚ adrenaline and atropine‚ and increased frequency of stimulus. Regarding Figure 1‚ the regular heartbeat and contraction force of the toad was identified to demonstrate the difference between atrial contractions

According to National Geographic‚ there were only 3‚000 cane toads (also known as Bufo marinus) brought into to Queensland‚ Australia. Now there is an estimated number of over two billion ([2]). With this large number of cane toads‚ their impact on the environment is much greater than was ever anticipated. Cane toads reproduce extremely

MANY PROCESSES MUST TAKE place within the skeletal muscle fibres in order for muscle contraction to occur. The cross bridge cycle‚ process by which the muscle length is shortened as myosin heads‚ extending from the myosin filaments‚ interact cyclically in a rowing motion with the actin filament (Rayment et al. 1993)‚ is one of the crucial mechanical events required. The mechanism is initiated when an ATP molecule is bound to a myosin head. An enzyme within the head. known as ATPase‚ hydrolyzes the
