BISON RELSEASE: European bison roaming in Germany for the first time in 400 years
by Wildlife Extra staff
On 11 April 2013, a fence was cut down in the Bad Berleburg region of Germany. Nothing unusual in that, except that cutting the fence allowed a small herd of European bison (sometimes known as wisent) to become the first free roaming herd in Western Europe for 400 years.
The opening of the fence released a small herd, consisting of one adult bull, five cows and two calves, into a 10,000 hectare forest. Two of the animals are fitted with radio transmitters to allow scientists to track and follow them. The animals will roam entirely free in the large forests of the Rothaar Mountains around Bad Berleburg in North Rhine-Westphalia. It is hoped that the herd will grow to about 25 animals. The World Wide Fund For Nature (WWF) called the project a ground-breaking step in nature conservation of Germany…

New Population of Rare Irrawaddy Dolphins Found in the Philippines
Irrawaddy dolphins found off the coast of the Island Palawan

April 2013. - A new population of critically-endangered Irrawaddy dolphins has been found in the Philippines by Mavic Matillano of the WWF Palawan team. Spotted by chance off Palawan - along the coastline of the West Philippine Sea - this pod of rare marine mammals, locally called Lampasut, was observed displaying typical behaviour, foraging for prey around lift net fish traps sitting approximately one kilometre offshore.
Previous populations of these dolphins - gifted with features that offer the barest hint of a congenial smile - have been documented in Malampaya Sound, as well as off the island of Panay. The Quezon pod represents the fourth known group of Irrawaddy dolphins reported in the Philippines…

The Fourier series approximation for the Step Function (or Square Wave) is 1/n * Sin(n*pi*x)/L for odd values of n. Here is the expansion, plotted up to n=49. Below are the individual waves and above is the progression of their added values!
