Pattern and process in a New Zealand subalpine plant community
Tóm tắt
Two dynamic patterns found in subalpine herbaceous communities of the North Island of New Zealand are described. These show remarkable similarities with patterns in comparable areas of the northern hemisphere described by Watt (1957) and Burges (1951) as “eroded Rhacomitrietum”. While the genera, except for Rhacomitrium are distinctive, the families represented by other basic zone formers in this pattern are in related families in both hemispheres. The place of Empetrum (Ericaceae) is taken by Dracophyllum (Epacridaceae) in New Zealand. Vaccinium has its equivalent in Gaultheria (both Ericaceae). It is suggested that when further information is obtained, some interesting comparisons and generalisations will be possible.
