  abstract = {{T}o describe the composition of the penultimate glacial {B}razilian {A}tlantic forest, we analyzed pollen, charcoal and diatoms deposited in the section from 871 to 1400 cm of core {CO}14 drilled in the {C}olonia basin in southeastern {B}razil. {T}he landscape was characterized by a cool grassland with three conifer genera: {A}raucaria, {P}odocarpus and {E}phedra. {T}otal arboreal pollen frequency did not change during the transition from glacial to interglacial conditions. {C}hanges in {P}odocarpus frequency and concentration showed out-of-phase responses with austral summer insolation at an orbital scale while, at a millennial scale, both northern and southern hemisphere ice volume controlled the interplay between positions of the {I}nter-{T}ropical {C}onvergence {Z}one and {S}outh {T}ropical {F}ront ({STF}), which in turn defined the latitudinal distribution of rainfall. {T}he disappearance of {P}odocarpus and the decrease of {A}raucaria observed between similar to 167 and 160 ka were related to a dry interval which was not observed elsewhere. {D}uring {T}ermination {II} a progressive decrease in conifer pollen taxa was in phase with a southward shift in the {STF} and increase in {A}tlantic sea surface temperatures. {O}ur results show that southern hemisphere conifer distribution is strongly linked to austral summer insolation and winter precipitation and will be threatened by the southward expansion of the summer rainfall boundary.},
