    ..The results of this study indicate that chemical defense in a dendrobatid poison frog is dependent on geographic location and habitat type, which presumably controls the abundance and nature of alkaloid-containing arthropods...

    ..pumilio, as well as in the diets of other poison frogs. The results of this study indicate that mites are a significant arthropod repository of a variety of alkaloids and represent a major dietary source of alkaloids in poison frogs...

    J Nat Prod 73:317-21. 2010
    ..The majority of alkaloids present in the skin of O. pumilio appear to be of oribatid mite origin, supporting the importance of these dietary arthropods in the chemical defense of poison frogs...
