Plant communities as bioclimate indicators on Isla Navarino, one of the southernmost forested areas of the world Gayana Botánica
Molina,José Antonio; Lumbreras,Ana; Benavent-González,Alberto; Rozzi,Ricardo; Sancho,Leopoldo G..
ABSTRACT Variation in climactic vegetation with altitude is widely used as an ecological indicator to identify bioclimatic belts. Tierra del Fuego is known to undergo structural and functional changes in forests along altitudinal gradients. However there is still little knowledge of the changes in plant-community composition and plant diversity -including both forests and tundra and their area of contact (krummholz)- and their relation to climatic factors along an altitudinal gradient. This study focuses on Isla Navarino (Chile), at the eastern part of Beagle Channel, included in the Cape Horn Biosphere Reserve. Numerical analysis revealed four community types along the cited gradient: a) mixed forest of Nothofagus betuloides and Nothofagus pumilio...
