Abstract: Here, we describe pollen grains extracted from a Pleistocene-Holocene sediment core (BU-91-GL-05; 22°48'45"S; 41°54'13"W) taken from the Albacora Slope (22°48'45"S; 41°54'13"W), located in the Campos Basin of the northern region of the state of Rio de Janeiro, Brazil. The analysis resulted in the identification and morphological description of 46 types of pollen: one of a gymnosperm genus (Podocarpus); and 45 of angiosperm taxa across 27 families-one family of monocotyledons (Poaceae) and 26 families (30 types… Show more

“…3A), corroborating simulated LGM biome distributions based on global vegetation models (11). Analyses of a marine sediment core from the southeastern Brazilian continental margin revealed a wide spectrum of pollen types, including those representative of dense and semideciduous forests, coastal scrublands, and a low frequency of grasses (12). In contrast, another marine core from the same region suggested maximal grassland expansion and rainforest reduction during the LGM (13), with the two datasets thus reflecting regional variation in forest cover on the shelf.…”

“…However, Ilex species can be also found in varzea forests of the Amazonian lowlands (Wittmann et al 2006;Wittmann et al 2013), and certain Podocarpus species can occur in gallery forests of tree savannahs in central Brazil and in other types of savannah vegetation bordering the Amazon and Peruvian plains (Ledru et al 2007). The pollen from these species often relies on anemophilous transport for dispersal (Behling et al 2002;Freitas & Carvalho 2012;Freitas et al 2013), and there are records of Hedyosmum specimens collected near the town of Humaita, close to our study area (Chamberlain et al 2014). Furthermore, all these species can easily reach the Amazonian lowlands, especially by river transport (Hammen & Hooghiemstra 2000).…”

“…Throughout the analyzed core ( Fig. 1) the relationship between the identified spores (fossil) and the modern flora of pteridophytes found in the vegetation formations on the continent is clear (Freitas 2005;Freitas et al 2013). Therefore, these results along with the pollen data constitute an inventory of the Quaternary flora of SE Brazil, and may be a useful tool for other paleoclimate and paleoenvironmental reconstructions conducted in the SE region of Brazil.…”
