A type of trap for sampling the mesovoid shallow substratum (MSS) fauna

Heriberto López, Pedro Oromí

Abstract


A special type of pitfall trap for sampling the MSS is presented, explaining in detail its design and installation. This trap can be used repeatedly for a long time, with minimal disturbance of the habitat once the system is stabilized. It is made of a PVC pipe with abundant small holes in its lower half, with a jar inside at the bottom containing the bait and preservative liquid. The pipe is set vertically underground in such way that the holes reach the MSS, and the top remains a few centimetres below surface, closed with a cap and covered by soil. The use of this trap in the volcanic MSS on the Canary Islands (Spain) has shown surprising results.
