Description

Over recent decades, climate changes, especially revealed through alteration in rainfall patterns, with apparent intensification of the dry season, have been documented throughout Latin America. At the same time, this region of the globe has displayed strong economic growth along with profound changes in land use and emission of air pollutants. Long-term studies have shown that functional groups of plants from tropical and sub-tropical rainforests and savannas, the largest and most diverse biomes in the region, present different sensitivities to climate change, increasing CO2 and atmospheric deposition of nitrogen, for example, resulting in evident changes in community structure and dynamics. In general, these factors have led to a reduction in plant diversity. Ozone, though less studied in the region, has been monitored in the major urban centres, and its relation to land use change, as through biomass burning, has become evident. The main results of plant responses to pollutants and climate change are presented.
