The dynamics of marine stepwise mass extinction
نویسندگان
چکیده
Mass extinction is characterized by the loss of 50 - 90 + percent genetically and ecologically diverse species within 1 3.5 Myr intervals. Three conflicting theories exist: (1) Graded Extinction; (2) Stepwise (3) Catastrophic Extinction. These can only be adequately tested with high resolution (cm-scale) stratigraphic data spanning entire mass interval adjacent strata. Such are presently available for Eocene-Oligocene (E-O), Cretaceous-Tertiary (K-T) Cenomanian-Turonian (C-T) extinctions. In general, prevalent uniformitarian philosophy use modern Earth/Life system as a model Phanerozoic has hindered search for, expectations of, high-resolution critical) to research. The "model" predicts highly variable, environmentally biologically resilient systems predominantly autocyclic response large-scale forcing mechanisms.

متن کاملDynamics of origination and extinction in the marine fossil record
The discipline-wide effort to database the fossil record at the occurrence level has made it possible to estimate marine invertebrate extinction and origination rates with much greater accuracy. The new data show that two biotic mechanisms have hastened recoveries from mass extinctions and confined diversity to a relatively narrow range over the past 500 million years (Myr). First, a drop in di...
متن کاملOrigination, extinction, and mass depletions of marine diversity
—In post-Cambrian time, five events—the end-Ordovician, end-Frasnian in the Late Devonian, end-Permian, end-Triassic, and end-Cretaceous—are commonly grouped as the ‘‘big five’’ global intervals of mass extinction. Plotted by magnitude, extinction intensities for all Phanerozoic substages show a continuous distribution, with the five traditionally recognized mass extinctions located in the uppe...
متن کاملEnd-Cretaceous marine mass extinction not caused by productivity collapse.
An asteroid impact at the end of the Cretaceous caused mass extinction, but extinction mechanisms are not well-understood. The collapse of sea surface to sea floor carbon isotope gradients has been interpreted as reflecting a global collapse of primary productivity (Strangelove Ocean) or export productivity (Living Ocean), which caused mass extinction higher in the marine food chain. Phytoplank...

In recent decades, necessity to protect environment has been a serious concern for all people and international communities. In appropriate development of human economic activities, subsistence dependence of the growing world population on nature decreases the natural diversity of ecosystems and habitats day by day and provides additional constraints for life and survival of wildlife. As a resu...
