Abstract

How plants will respond to climate change in carbon partition is still uncertain, particularly in trees of coastal ecosystems (mangrove and restinga) in southeastern Brazil where temperature and rainfall are expected to rise until the end of this century. The aim of this study was to provide an understanding of the dynamics of partitioning carbon reservoirs in frequent species of mangrove and restinga vegetation, in the seasons marked by climatic contrasting (dry and rainy season). For mangrove species, carbon partition was not influenced by seasonal climate variation. For restinga species, higher levels of NSC and cellulose occurred in the rainy season, suggesting possible accumulation of these carbon reservoirs in restinga vegetation in response to temperature and rainfall rise.
