Preliminary scope of work

Téma je založeno na změnách rychlostí evoluce ježovek (i dalšího bentosu) na pozadí environmentálních a klimatických změn křídového greenhouse. Práce je rešeršní s možností omezeného/spíše minimálního terénního výzkumu (svrchní turon). V rámci BP by studentka měla zhodnotit chování společenstev ježovek v rámci Weissert eventu, OAE1 (a-c), OAE2, klimatických variací svrchního turonu, OAE3 a vymírání ve spodním maastrichtu a na K/Pg hranici.

Preliminary scope of work in English

The topic is based on changes in the rate of evolution of sea urchins (and other benthos) in relation to environmental and climatic changes of the Cretaceous greenhouse. The work is exploratory with the possibility of limited/rather minimal field research (Upper Turon). Within the BP, the student should evaluate the behavior of sea urchin communities within the Weissert event, OAE1 (a-c), OAE2, climatic variations of the Upper Turonian, OAE3 and extinction in the lower Maastrichtian and at the K/Pg border.
