Ecological Structure of Recent and Last Glacial Mammalian Faunas in Northern Eurasia: The Case of Altai-Sayan Refugium
Pleistocene mammalian communities display unique features which differ from present-day faunas. The paleocommunities were characterized by the extraordinarily large body size of herbivores and predators and by their unique structure consisting of species now inhabiting geographically and ecologically distinct natural zones. These features were probably the result of the unique environmental con...

متن کاملDevelopment of Cenozoic deep-sea benthic foraminiferal faunas in Antarctic waters
Upper abyssal to lower bathyal benthic foraminifera from Ocean Drilling Program Sites 689 (present water depth 2080m) and 690 (present water depth 29I4m) on Maud Rise (Antarctica) recorded changes in deep-water characteristics at high southern latitudes during the cenozoic. The benthic foraminiferal faunas show only minor differences as a result of the difference in water depths between the sit...
متن کاملSeasonal Variability of Benthic Foraminiferal Faunas at 1000 M Depth in the Bay of Biscay
A 1000-meter-deep station in the Bay of Biscay (station A) was sampled 10 times between October 1997 and April 2001 for the purposes of studying the temporal variability of live foraminiferal faunas in the 63–150 mm and .150 mm size fractions. The results are compared with those obtained earlier for a 550-m-deep station nearby. The study area is marked by prolonged, two-month spring blooms and ...
