In general, the various methods used in species distribution modelling can be classified in two categories, one set of methods require species presence and absence data for model…

Climate change impacts have resulted in ecological changes that cause physiological stress on species and can affect population dynamics. Sources of stress include biotic factors such as predation and competition, as well as abiotic factors such as extremes in temperature and increased frequency of fires and drought. For example, global temperature levels have and are…

The concepts of Thermodynamics are extremely important on the application for thermal systems design. As they present heat transfer process by conduction on the warmth source and sink, evaporation and condensation of the working fluid, the whole cycle that those devices perform are often well explained by the laws of thermodynamics The Laws of Thermodynamics…

Dolphins are a kind of our favourite sea creatures. Everyone loves them. But, most of us only know a few things about them. Have you heard of the pink dolphins which are much more cute? Today, I’d love to present some good news about a dolphin birth. A dolphin mom who is called Pinky has…

“Electricity conservation is the number one way to save money” Cha-ching cha-ching.

The conservation status of koala in every state of Australia fluctuates according…

Emperor Penguins have to survive in some of the harshest weather conditions in the world (as low as -40°Cand 200 km/h winds). They have a set of features that help them adapt to this. These penguins have large reserves of sub-dermal body fat to insulate them. They have many layers of stiff short scale-like-feathers which…
