Modern geography is based on ecological thinking. In this paper some geoecological notions are discussed: the scales and levels regarding spatial magnitude and complexity, the "hierarchy" of landscape units and especially the scale of time and the concept of the superimposing "stamps". This last mentioned concept is very important in relation to the problem regarding regionalization and its possibilities.Three "stamps" are recognized: 1. the substrate, 2. the climatic conditions, 3. the human (no6tic) influence. Holistic regionalization in which all elements (including the human influences) are telling to full advantage, is unsatisfactory.
Abstract. Es wurden in dieser kurzen Arbeit Literaturangaben über die quartären Klimaänderungen gesammelt, die aus dem karibischen Gebiet und den benachbarten Teilen Südamerikas bekannt sind. Man kann feststellen, daß in Kolumbien, Nordwest-Venezuela, Aruba, Curasao, Bonaire und Barbados pluviale Perioden etwa synchron waren mit den Glazialen in Gebieten höherer Breite. Die Daten aus Guyana und Suriname lassen zwar noch keine endgültigen Schlüsse zu, doch deutet vieles darauf hin, daß dort während der Glazialzeiten trockenere klimatische Bedingungen herrschten als heute. Das würde einer Verschiebung der „ariden" Zone um etwa 10° entsprechen.
