Resumen:
The GLORIA target
region at Cumbres Calchaquíes in Tucumán, Argentina, is the first GLORIA site
in the country. This isolated mountain range is a much older than the Andes,
and straddles the gradients between high rainfall eastern slopes and dry
western slopes, making it particularly appropriate to detect the effect of
climate change on vegetation responses. We present the first results of high
Andean vegetation monitoring, in the context of the GLORIA project in Tucumán.
We established the bases for the long term monitoring, to study the effect of
climate change on plant communities. The area is highly diverse compared with
other Andean Gloria sites. Vascular plant richness declines with altitude, and
plant cover decline even more. Diversity and evenness altitudinal pattern
changes are less clear. While HUA showed a lower diversity compared with all
other sites, its α diversity was higher. Both methods, 1m2 and the
entire area samplings are needed to capture the whole species richness.
