  abstract = {{I}n the "{L}agoa {C}ampestre" (lake) of {S}alitre (19°{S}, 46°46'{W}, 970 m elev.), there are plant taxa belonging to many ecological groups that are encountered nowhere else at this latitude. {F}requent incursions of polar advections causing cooling and humidity, a cool and foggy climate in the middle of the depression and warmer temperatures on the surrounding slopes help to maintain all these groups within a fairly restricted area. {L}ate {P}leistocene-{H}olocene climatic change has had a considerable impact on the flora and vegetation of {S}alitre. {T}he pollen record of the 6 m deep core {LC}3 shows how cold forest trees such as #{A}raucaria angustifolia$ and #{D}rimys brasiliensis$, semi-deciduous forest, halophytic plants and peat bog started to develop on this site. {T}he initial period, between c. 50,000 and 40,000 yr {B}.{P}., was an arid phase not recorded in any other neotropical lowland site. {I}t was followed by a period of high moisture levels (40,000 to 27,000 yr {B}.{P}.) with a maximum estimated at c. 35,000 yr {B}.{P}. {T}he {L}ate {G}lacial maximum is missing because of a gap in sedimentation. {H}umidity gradually increased during the {L}ate {P}leistocene, between 16,000 and 11,000 yr {B}.{P}. {T}he early {H}olocene, 9500 to 5000 yr {B}.{P}., is characterized by a more marked seasonal pattern and higher temperatures, reaching a maximum c. 5000 yr {B}.{P}. {T}he spread of semi-deciduous forest between 4000 and 3000 yr {B}.{P}. attests to a return of humidity. {C}omparison with the {S}erra {N}egra section (19°{S}, 46°45'-46'{W}, 1170 m elev.) not far from {S}alitre confirms the high moisture rates recorded at c. 35-40,000 yr {B}.{P}. (although temperatures were cooler at the altitude of {S}erra {N}egra, as is attested by the presence of #{A}raucaria$ forest) and also confirms the strong impact of polar advections on the climate of {S}outheastern {B}razil.
