INDEX OF ECOLOGICAL SIGNIFICANCE (IES) AS A TOOL TO PHYTOSSOCIOLOGICAL AND CONSERVATION STUDIES FOR MOSS SPECIES IN ADMIRALTY BAY AREA, KING GEORGE ISLAND, ANTARCTICA.

The Antarctic plant distribution depends on the environmental factors, like geomorphological conditions, as surface's stability, rock type and aeolian erosion. It establishes clear home ranges, leading some mosses species to be highly correlated to local geomorphology. During the austral summer...
