Lentic zonation . . . these are areas of
standing water ("stillwater")
ponds and lakes, that
are primarily "depositional", i.e., they gather siltation; they are
characterized by the presence of 3 distinct zones, as depicted below.
Insect numbers will be highest in the "littoral
zone", with some concentration of specific species found in the "limnetic"
zone. The "profundal" zone
is the least populated by insects.
