Diatom frustules, pollen grains, insects, and other animal remains are preserved in these areas of poor decomposition. These remains are used by paleolimnologists to reconstruct a picture of past plant and animal life and environmental conditions.
palynology The science of reconstructing the past flora and past climate from pollen data obtained from lake and bog sediments. The fossil pollen record is a function of the regional flora and vegetation at a given time and location.
Breeding orchards involve controlling the source of pollen used to fertilize female flowers. This process is expensive and difficult because it involves collecting pollen from male flowers and fertilizing female flowers by hand.
