Introducing herbivorous grass carp or predatory bluegill sunfish into ponds poses a threat to the survival of many smaller amphibians. Bullfrogs, which overwinter in ponds, also reduce the populations of smaller amphibians. Cricket frogs reared in enclosures on golf course ponds performed similarly to natural reference ponds.

This nematode penetrates and feeds on soybean roots impairing the plant’s ability to absorb water and nutrients, decreasing their yield potential.
