Summary: As changes in climate have been happening rapidly, with in thermal regimes and water balance, becoming a large-scale threat to the environment. As the plants will respond by a transmission, and there is little information on the responses to the carbon reservoirs to changes in temperature and precipitation. Thus, it is important to identify as possible vulnerabilities of the functional species of the Atlantic Forest in a climate change scenario. The objective of this study was to evaluate the risk of vulnerability of carbon reservoirs in restinga and mangrove tree species, in relation to
temperature and atmospheric variations in natural conditions. Leaf and stem samples were collected from three functional species of the restinga, Clusia hilariana, Ocotea notata and Protium icicariba, and the Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle mangroves. Samples were collected in the fall of 2016 and in the summer of 2017. The non-structural carbohydrates (starch, sucrose and total soluble carbohydrates) and structural carbohydrates (cellulose and hemicellulose) were determined for the vulnerability assessmen, lignin. As average data and comparisons applying, the analysis of variance and subsequent Tukey test at the level of 5% (P <0.05) significance. The ecosystems responded differently to the carbon pools, in front of the instant of the climate exposed. The mangrove presented
only one reservoir of structural carbon, a cellulose. While the restinga exhibited
greater variation in its carbon, starch, sucrose and cellulose reservoirs. Both in
conditions of higher precipitation and lower temperature. The restinga can be
considered with greater vulnerability to the current changes of temperature and precipitation in which the ecosystems are being submitted.
Key words: Climate change carbon reservoirs restinga mangrove vulnerability
