Abstract

Studies of processes connected with various Phanerozoic mass extinctions suggest that although these events differ in details from each other, they manifest certain global mutual similarities. There is a number of detailed data on the mass extinction phases but only scarce information on the survival and recovery intervals directly following the crises. In connection with the biota crises studies also the problem of refugia started to be discussed very intensively, because namely fossil refugia can contain fossils representing important connecting links getting over boundaries of mass extinctions. The aim of this article is to join some general considerations of possible refugia structures, functions and spatial and temporal changes to the discussion being in progress.

Kurzfassung

Die Studien über verschiedene phanerozoische Massenaussterben bestätigen, daß, obwohl diese Ereignisse in Details verschieden sind, sie gewisse globale Ähnlichkeiten haben. Es gibt viele ausführliche Daten über die Zeitspannen der Massenaussterben selbst, aber nur wenige Daten über die unmittelbar folgenden Intervalle des Überlebens sowie der Wiederaufnahme der (Paläo-)Ökosysteme. Im Zusammenhang mit den Studien über einzelne biotische Krisen kommt es heutzutage auch zu einer lebhaften Diskussion über das Problem der Refugien. Eben diese fossilen Refugien können nämlich solche Fossilien enthalten, die die Grenzen der Massenaussterben überschreiten. Das Ziel dieses Artikels ist es, mit einigen allgemeinen Modellen der möglichen Struktur und Funktion der Refugien sowie ihrer räumlichen und zeitlichen Änderungen zu dieser Diskussion beizutragen.
