Scientists have joined forces to save magical Madagascar by using a new method they hope to apply to other hot spots of biodiversity. For full details you can check my colleague Deborah Zabarenko’s story.

As someone who has had the great privilege of visiting this island continent twice I can only say: “Right on!”

Madagascar is a classic example of natural selection at work: most of its species have evolved in splendid isolation because the island broke free from the rest of Africa tens of millions of years ago. 

This is what evolution and natural selection are all about. It is no coincidence that Charles Darwin and Alfred Russel Wallace separately stumbled upon this profound notion in the 19th century while observing life on islands — or, more specifically, the difference to be found in life on islands often only a few miles apart. 

Madagascar, because of its size and the length of time it has been a cast away, is a prime an example of natural selection run riot.

Its snakes have no venom because that is an evolutionary trait they picked up after Madagascar and the rest of Africa went their separate ways.

It has boa constrictors (which I have observed in its forests) which are found nowhere in Africa but are found in South America. Why? How? Because, or so goes one theory I have heard, Madagascar and South America BOTH broke free from Africa at one point. So it stands to reason that they might both keep something that died out in Africa and vice versa.

That is the dynamic of natural selection.

I could go on and on and on. Madagascar is most famous for its roughly 70 species on lemurs, dainty primates that come in all shapes and colors. The largest among them, the indri, has a haunting cry that belies its small stature and which sent tingles down my spine the first time I heard it.

Much of the indri population is now restricted to a fragment of isolated habitat in a protected reserve. An island on an island.

For a good popular introduction to the study of island life I would recommend David Quammen’s superb book “The Song of the Dodo.” It inspired me to go to Madagascar in the first place with my wife when I was a Johannesburg-based correspondent.

And if you really want to see natural selection at work on an island, go to Madagascar yourself. Eco-tourism can help preserve species by giving rural people an economic incentive not to hunt them or destroy their habitat.  And that can only help the scientists and their new efforts to save this cradle of weird and wonderful evolution.

Three giant wind turbines are helping the Galapagos Islands in the Pacific Ocean towards a goal of eliminating use of fossil fuels by 2015 — and no birds have been killed in a six-month pilot scheme despite worries in many nations that big blades and bird brains don’t mix.

The Galapagos are home to mocking birds, finches, petrels, blue-footed boobies, doves, albatrosses and other exotic species many of which only live on the islands. Studies of Galapagos birds helped British 19th century naturalist Charles Darwin work out his theory of evolution.

“In six months of pilot operations there have been no bird kills,” said Melinda Kimble of the U.N. Foundation, a sponsor of the $10.8 million project led by power producers including American Electric Power and also backed by Ecuador’s government.

Power producers studied birds’ flight paths and nesting habits to decide the siting of the turbines and reduce risks of collisions.

“There seems a very broad support for the project, right down to school kids,” said Kimble after attending an official dedication ceremony late last month on San Cristobal, the island with the biggest human population.

The turbines have a generating capacity of 800 Kwh and will provide up to about 80 percent of San Cristobal’s electricity needs in windy months, halving the need for diesel fuel to power the island.

The shift to renewable energy for the islands was spurred after the oil tanker Jessica ran aground with 160,000 gallons of diesel fuel in 2001 — some oil leaked but a catastrophe was narrowly averted thanks to favourable winds and tides.

Bird lovers say that turbines from California to Denmark often kill birds.

But are the turbines a threat — or is it just a case of siting them with care?
