Two new types of noose for capturing herps.

We present two new types of noose for capturing herps, which allow adapting the size of the loop to the size of prey rapidly. We use a plastic ring to make the loop: the thread moves perfectly without any impediment or friction, and remains in good conditions for a longer time. The plastic ring can be made during fieldwork. Both new types of noose increase capture effectiveness, as it is possible to noose different types of preys with a simple and rapid adaptation of the loop. We have tested this methodology in different species of lacertids, some snakes under rocks, and also some amphibians. [ABSTRACT FROM AUTHOR]
