Barred Tiger Salamanders and fathead minnows in amphibian type funnel trap
Detailed Description
Barred Tiger Salamanders and fathead minnows in amphibian type funnel trap, Kidder County, ND.
The duration and amount of water in a wetland and the availability of invertebrate prey are very important predictors of salamander morphology. In North Dakota, cannibal morph barred tiger salamanders have been observed to co-occur with high densities of fathead minnows (Pimephales promelas), which might be a result of increased competition for food.
