Ramp v. Pitfall

Part of the Hopland Bioblitz effort is comparing two styles of traps for ground active arthropods, ramp traps and pitfall traps. There is a lot more sorting and identifying to do, but the tenebrionid catch visually appears to tell us something. Just in terms of absolute numbers of tenebrionid beetles, the ramp (R) traps did about the same as the pitfalls (PF) for habitats 1-4. Habitat 5 looks different.


Samples from Hopland REC. Ramp traps (R) and Pitfall traps (PF) from sites 1-4.
