When I will be back in the Netherlands I will elaborate some more on the specific experiments. Click on the …
Turtles @ Derawan

The net is 5cm in diameter to prevent the turtles from getting stuck into the net. …

In this movie you can see the transport of chloroplasts over a cytoplasmatic …

Here are some pictures of the experimental set-up: A detail of on of the 40 shoots …
