Investigations on the Ecology and Production - Biology of the Floating Meadows ( Paspalo - Echinochloethum) on the Middle Amazon. Part II. The Aquatic Fauna in the Root Zone of Floating Vegetation
(1973) Junk, Wofgang J.
Besides their importance for primary production, (JUNK 1970) the floating vegetation in the varzea region of the Amazon must be taken into consideration as a very important factor for the secondary production in the waters of this region as well. The floating stands represent a biotope which, with few exceptions, offers very good living conditions for aquatic animals. Accordingly they are populated with a large number of individuais and species.
Crocodiles and the nutrient metabolism of Amazonian Waters
(1973) Fittkau, Ernst Josef
Am Beispiel des zentralamazonischen Regenwaldes wird ein ökologisches Prinzip auf,gezeigt, das die Struktur eines tropischen Ökosystems bei einem zwar ausgeglichenen , aber sehr seringen Nährstoffangebot bestimmt. Dieses Prinzip besagt . daíß die Biozönose solch eines Systems umso stabiler ist, je arten- und individuenreicher sie ist, d.h. je differenzierter
