“…Notwithstanding some of the anomalies mentioned, the biomisation method applied to Latin American pollen data can reconstruct large-scale vegetation patterns despite many pollen taxa having different ecological interpretations under different environmental settings (Grabandt, 1980), representation of parent vegetation by pollen likely to be subject to inter-annual variability (Behling et al, 1997b), and tropical vegetation is difficult to reconstruct through pollen assemblages (Bush, 1991;Mancini, 1993;Bush and Rivera, 1998;Behling et al, 1997). These factors demonstrate the importance of basing the input matrices for the biomisation process on all the available ecological information that allowing for the multiple assignment of the pollen taxa to the PFTs.…”

Abstract. The biomisation method is used to reconstruct Latin American vegetation at 6000±500 and 18 000±1000 radiocarbon years before present (14C yr BP) from pollen data. Tests using modern pollen data from 381 samples derived from 287 locations broadly reproduce potential natural vegetation. The strong temperature gradient associated with the Andes is recorded by a transition from high altitude cool grass/shrubland and cool mixed forest to mid-altitude cool temperate rain forest, to tropical dry, seasonal and rain forest at low altitudes. Reconstructed biomes from a number of sites do not match the potential vegetation due to local factors such as human impact, methodological artefacts and mechanisms of pollen representivity of the parent vegetation. At 6000±500 14C yr BP 255 samples are analysed from 127 sites. Differences between the modern and the 6000±500 14C yr BP reconstruction are comparatively small; change relative to the modern reconstruction are mainly to biomes characteristic of drier climate in the north of the region with a slight more mesic shift in the south. Cool temperate rain forest remains dominant in western South America. In northwestern South America a number of sites record transitions from tropical seasonal forest to tropical dry forest and tropical rain forest to tropical seasonal forest. Sites in Central America show a change in biome assignment, but to more mesic vegetation, indicative of greater plant available moisture, e.g. on the Yucatán peninsula sites record warm evergreen forest, replacing tropical dry forest and warm mixed forest presently recorded. At 18 000±1000 14C yr BP 61 samples from 34 sites record vegetation reflecting a generally cool and dry environment. Cool grass/shrubland is prevalent in southeast Brazil whereas Amazonian sites record tropical dry forest, warm temperate rain forest and tropical seasonal forest. Southernmost South America is dominated by cool grass/shrubland, a single site retains cool temperate rain forest indicating that forest was present at some locations at the LGM. Some sites in Central Mexico and lowland Colombia remain unchanged in the biome assignments of warm mixed forest and tropical dry forest respectively, although the affinities that these sites have to different biomes do change between 18 000±1000 14C yr BP and present. The "unresponsive" nature of these sites results from their location and the impact of local edaphic influence.

“…In the last decade, however, an increasingly large number of studies that have been conducted started to apply different techniques of Multivariate Analysis in Palynology, such as Detrended Correspondence Analysis -DCA, Principal Component Analysis -PCA, Two-way Indicator Species Analysis -TWINSPAN, Non-metric Multidimensional Scaling -NMDS, and even Canonical Correspondence Analysis -CCA (e.g. , Rodgers and Horn 1996, Behling et al 1997, Haberle and Bennett 2001, Stutz and Prieto 2003, Urrego et al 2005, De Toledo and Bush 2008a.…”

“…Three types of samples have been used in these studies: artificial pollen traps (Tauber 1974, Bush 1992, Behling et al 1997, Bennett and Hicks 2005; sedimentary surface samples from soil, peat bogs and lake, also known as mud-water interface (Rodgers and Horn 1996, Phillips et al 1997, Vincens et al 1997, Willard et al 2001, and finally samples from moss cushions (Weng et al 2004). Even though, there are many studies of modern pollen rain that use samples from different origins to characterize present vegetation.…”

“…The first systematic pollen rain study on southern Atlantic rain forest was published by Behling et al (1997) Although these are the only studies on modern pollen distribution published for Rio de Janeiro State, these data were not systematically used on the interpretation of their respective fossil pollen records , Barreto et al 2007). …”
