Слайд 2Subject
Coleopteran-any member of the insect order Coleoptera, consisting of the beetles and
weevils. It is the largest order of insects.
Слайд 3Type of sediments
Generally coleopteras yield more terrestrial than aquatic specimens.
This is probably due to a combination of factors, including
greater species diversity in terrestrial habitats, and the concentration of wind-blown specimens in catchment basins.The ground beatle, showing parts of exoskeleton commonly used for fossil indication
Слайд 4Time period
The remains of beetles are often abundant and well-preserved
in Quaternary lacustrine sediments.
Слайд 5What could be defined
-ancient substrates
-water temperature
-air temperature
-regional vegetation (both aquatic
and terrestrial)
-sensitive to the trophic status and pH of the
water
Слайд 6Reconstructions
The principal method of paleotemperature estimation from fossil beetle MCR
method (Atkinson et al., 1986).
Geographical overlap method (Atkinson et
al., 1986).Regional examples from Europe serve to illustrate the quality and kinds of paleoenvironmental reconstructions that have been drawn from fossil insect assemblages from lake sediments.
