Today's featured article

The Green and Golden Bell Frog is a ground-dwelling tree frog native to eastern Australia. Measuring 11 centimetres (4.3 in) in length, the Green and Golden Bell Frog is one of the largest Australian frogs. Many populations, particularly in the Sydney region, are in areas of frequent disturbance, including golf courses, disused industrial land, brick pits and landfill areas. Once one of the most common frogs in south-east Australia, the Green and Golden Bell Frog has undergone major population declines, leading to its current classification as globally vulnerable. Population numbers have continued to decline and major threats include habitat loss and degradation, pollution, introduced species, and parasites and pathogens, such as the amphibian chytrid fungus.

Today's featured picture

A male Mallard in mid-flight. The fundamentals of bird flight are similar to those of aircraft. Lift force is produced by the action of air-flow on the wing, which is an airfoil. This occurs because the air has a lower air pressure just above the wing and higher pressure below. When a bird flaps its wings they continue to develop lift but they also create an additional forward and upward force, thrust, to counteract its weight and drag.
