“…The peak of high pollen-DCA axis 2 scores between 1500 and 1650 was nested within this period, suggesting that even though productivity increased as climate changed, compositional change towards more mature forests lagged climate. Accordingly, that lag was of ~100 years, a magnitude that has also been reported for other locations of the Yucatan Peninsula (Hillesheim et al, 2005).…”

“…On the other hand, vegetation response to environmental changes is much slower, with the extreme case of trees that can live for centuries, and therefore delay the response of the vegetation to environmental changes (Hartshorn, 1978). In fact, from the pollen record of the Yucatan Peninsula, it has been estimated that vegetation of the area lags environmental changes by ~100 years (Hillesheim et al, 2005). In Lago Verde, diatoms reached a maximum axis length of almost 4 SD (a complete species turnover), whereas pollen maximum was attained at 2.6 SD ( Table 1).…”

Fossil assemblages reflect the parental communities that produced them, and are in turn associated with specific environmental conditions. Thus, climatic and environmental changes are associated with changes in both the biotic communities and the fossil assemblages they produce. As a consequence, the environmental reconstruction of the past relies on the interpretation of multivariate fossil sequences that are commonly analyzed through dimensional rescaling techniques. Detrended correspondence analysis (DCA) has proven as an excellent technique to summarize ecological changes through time with the advantage of few prior assumptions and results that can be directly interpreted in terms of ecological turnover. In this paper we elaborate on a brief description of the technique and the interpretation of results, using a worked example on pollen and diatom data sets from Lago Verde (Los Tuxtlas, Mexico). With this worked example, we highlight the three basic ways in which DCA can provide useful approaches for a clear and relatively easy interpretation of the fossil data: i) identification of the ecological space through the a priori interpretation of species ordination; ii) localization of time slices within the ecological space defined by species, and quantification of the ecological turnover among samples; and iii) calculation of ecological distances as a means for putting individual samples into the historical context provided by the time frame in question.Keywords: Ecological distance, ecological turnover, ecological baseline, pollen, diatoms, detrended correspondence analysis (DCA). Resumen Los arreglos de fósiles coetáneos reflejan las comunidades parentales que los produjeron, las cuales están asociadas a su vez con condiciones ambientales particulares. Por lo tanto, los cambios climáticos y ambientales están inherentemente asociados con cambios en las comunidades bióticas y en los arreglos fósiles

“…Kullenberg piston coring in 2002 retrieved complete Holocene sections, but recovery was limited to the upper 6 m of sediment because a thick Holocene clay unit impeded penetration of the corer. These piston cores extended to $11.3 ka in the Preboreal period (Hillesheim et al, 2005), but did not recover the Younger Dryas chronozone (12.9-11.57 ka) when proxies from the Cariaco Basin indicate a dramatic change in climate during the last deglaciation (Hughen et al, 1996(Hughen et al, , 1998(Hughen et al, , 2004.…”

“…Lake water pH is high ($8.0) and saturated with calcium carbonate. The lake water is undersaturated with calcium sulfate today, but gypsum deposits at depth in sediment cores suggest that the water was saturated with CaSO 4 in the past (Hillesheim et al, 2005). The lake is fed by direct rainfall, runoff, and subsurface groundwater inputs.…”

a b s t r a c tDrill cores obtained from Lake Peté n Itzá , Peté n, Guatemala, contain a $85-kyr record of terrestrial climate from lowland Central America that was used to reconstruct hydrologic changes in the northern Neotropics during the last glaciation. Sediments are composed of alternating clay and gypsum reflecting relatively wet and dry climate conditions, respectively. From $85 to 48 ka, sediments were dominated by carbonate clay indicating moist conditions during Marine Isotope Stages (MIS) 5a, 4, and early 3. The first gypsum layer was deposited at $48 ka, signifying a shift toward drier hydrologic conditions and the onset of wet-dry oscillations. During the latter part of MIS 3, Peté n climate varied between wetter conditions during interstadials and drier states during stadials. The pattern of clay-gypsum (wet-dry) oscillations during the latter part of MIS 3 ($48-23 ka) closely resembles the temperature records from Greenland ice cores and North Atlantic marine sediment cores and precipitation proxies from the Cariaco Basin. The most arid periods coincided with Heinrich Events when cold sea surface temperatures prevailed in the North Atlantic, meridional overturning circulation was reduced, and the Intertropical Convergence Zone (ITCZ) was displaced southward. A thick clay unit was deposited from 23 to 18 ka suggesting deposition in a deep lake, and pollen accumulated during the same period indicates vegetation consisted of a temperate pine-oak forest. This finding contradicts previous inferences that climate was arid during the Last Glacial Maximum (LGM) chronozone (2172 ka). At $18 ka, Peté n climate switched from moist to arid conditions and remained dry from 18 to 14.7 ka during the early deglaciation. Moister conditions prevailed during the warmer Bolling-Allerod (14.7-12.8 ka) with the exception of a brief return to dry conditions at $13.8 ka that coincides with the Older Dryas and meltwater pulse 1A. The onset of the Younger Dryas at 12.8 ka marked the return of gypsum and hence dry conditions. The lake continued to precipitate gypsum until $10.3 ka when rainfall increased markedly in the early Holocene.

Phylogeographic Patterns of mtDNA Variation Revealed Multiple Glacial Refugia for the Frog Species Feirana taihangnica Endemic to the Qinling Mountains

Diversification patterns and demography of montane species are affected by Pleistocene climate fluctuations. Empirical cases from the Qinling Mountains (QM) region, which is a major biogeographic divider of East Asia, are few. We used DNA sequence data of the complete mitochondrial ND2 gene to detect effects of the Pleistocene glaciations on phylogeographic profiles of a frog species, Feirana taihangnica, which is endemic to the QM. Four distinct lineages consisting of seven sublineages were revealed. The strongest signal of biogeographical structure (F ct = 0.971, P \ 0.01) was found when populations were grouped according to these seven sublineages. One narrow secondary contact zone was detected in the middle QM between the lineage from middle QM and the lineage from eastern QM. Coalescent simulations indicated that this species colonized the QM region by a stepping-stone model. Divergences among lineages had likely been influenced by the uplift of the Tibetan Plateau during the late Miocene-tolate Pleistocene, as well as by the Pleistocene climatic cycles. Coalescent simulations also suggested that F. taihangnica populations have persisted through the Pleistocene glacial periods in multiple refugia across the QM region. Demographic analyses indicated that all lineages, except the lineage in the Funiu Mountains, have been experienced postglacial expansion of population size and distribution range. In conclusion, Pleistocene climate fluctuations and tectonic changes during the late Miocene-late Pleistocene have profoundly influenced the phylogeography and historical demography of F. taihangnica.
