                         depositional environmental change in southeastern Brazil, based 
                         upon the integration of particulate organic matter and stable 
                         isotope (C and N) data from a 136-cm sediment core from Lake Canto 
                         Grande. These proxies are used to explore the evolution of 
                         terrestrial and marine influence on the lake. Isotopic 
                         (\δ13C: \−27.87 to \−31.9; \δ15N: 
                         \−0.074.9) and elemental (total organic carbon - TOC: 
                         0.58%37.19%; total nitrogen - TN: 0.08%1.73%; C/N: 0.3 to 54.7) 
                         values recorded in Lake Canto Grande suggest that the sedimentary 
                         organic matter was derived from mostly C3 land plants and 
                         freshwater phytoplankton. Particulate organic matter and cluster 
                         analyses distinguished four associations characterized by the 
                         predominance of amorphous organic matter, followed by phytoclasts 
                         and palynomorphs. These results indicate two different phases of 
                         lake evolution. The first phase (136 - 65 cm; \∼10,943 cal 
                         yr. B.P. to \∼8529 cal yr. B.P.) is recorded by sand layers 
                         interbedded with mud, which contain amorphous organic matter (AOM, 
                         4559%) and phytoclasts (opaques - OP: 618%; non-opaques NOP: 
                         1723%) which indicate a floodplain area. The second phase (650 cm; 
                         \∼8529 cal yr. B.P. to \∼662 cal yr. B.P.) comprises 
                         mud, AOM (6886%) and palynomorphs (PAL, 816%) related to lake 
                         establishment comparable to modern conditions. Thus, 
                         characterizing particulate organic matter, in combination with 
                         stable isotopes, proved to be invaluable proxies for lacustrine 
                         paleoenvironmental change through the Holocene.",
