Short summary
Short summary
The long-term effects of alkalinisation upon peatland ecosystem functioning remains poorly understood. Using palaeoecological techniques, we show that intensive cement dust pollution altered vegetation cover and reduced carbon storage in an Estonian peatland. Changes also occurred during the 13th century following agricultural intensification. These shifts occurred following two-to-threefold alkalinity increases. Limited recovery was evident ~30 years post-pollution.

We present a continental dataset of pollen accumulation rates (PARs) collected by pollen traps. This absolute measure of pollen rain (grains cm−2 yr−1) has a positive relationship to current vegetation and latitude. Trap and fossil PARs have similar values within one region, so it opens up possibilities for using fossil PARs to reconstruct past changes in plant biomass and primary productivity. The dataset is available in the Neotoma Paleoecology Database.

Our study covers the full Holocene (the past 11 500 years) climate variability and vegetation composition and provides a test on how vegetation and climate interact to determine fire hazard. An important implication of this test is that percentage of tree cover can be used as a predictor of the probability of fire occurrence. Biomass burned is highest at ~ 45 % tree cover in temperate forests and at ~ 60–65 % tree cover in needleleaf-dominated forests.

Lake Ohrid is considered to be the oldest existing lake in Europe. Moreover, it has a very high degree of endemic biodiversity. During a drilling campaign at Lake Ohrid in 2013, a 569 m long sediment sequence was recovered from Lake Ohrid. The ongoing studies of this record provide first important information on the environmental and evolutionary history of the lake and the reasons for its high endimic biodiversity.

We analyse a southern Siberian stalagmite to reconstruct soil respiration, wildfire, and vegetation trends during the Last Interglacial (LIG) (124.1–118.8 ka) and the Holocene (10–0 ka). Wildfires were more prevalent during the LIG than the Holocene and were supported by fire-prone species, low soil respiration, and a greater difference between summer and winter temperature. We show that vegetation type and summer/winter temperature contrast are strong drivers of Siberian wildfires.

We present a global megabiome dynamics and distributions derived from pollen-based reconstructions over the last 21,000 years, which are suitable for the evaluation of Earth System Model-based paleo-megabiome simulations. We identified strong deviations between pollen- and model-derived megabiome distributions in the circum-Arctic areas and Tibetan Plateau during the Last Glacial Maximum and early deglaciation, as well as in North Africa and the Mediterranean regions during the Holocene.

The high-quality pollen records (collected from lakes and peat bogs) of the last 40 ka cal BP form north Asia are homogenized and the plant abundance signals are calibrated by the modern relative pollen productivity estimates. Calibrated plant abundances for each site are generally consistent with in situ modern vegetation, and vegetation changes within the regions are characterized by minor changes in the abundance of major taxa rather than by invasions of new taxa during the last 40 ka cal BP.

Here we reconstruct vegetation and precipitation, in eastern South Africa, over the last 32 000 years, by measuring the stable carbon and hydrogen isotope composition of plant waxes from Mfabeni peat bog (KwaZulu-Natal). Our results indicate that the late Quaternary climate in eastern South Africa did not respond directly to orbital forcing or to changes in sea-surface temperatures. Our findings stress the influence of the Southern Hemisphere westerlies in driving climate change in the region.

Results from Lago Edita, central-western Patagonia (47° S), allow examination of the timing and direction of paleoclimate signals during the last glacial termination (T1) in southern midlatitudes. Cold and wet conditions prevailed during T1, terminated by warm pulses at 13 000 and 11 000 yr BP. Delayed warming, relative to sites along the Pacific coast, raises the possibility that residual ice masses in the Andes induced regional cooling along downwind sectors of central Patagonia during T1.

The use of stalagmites for last interglacial continental climate reconstructions in Europe has been successful in the past; however to expand the geographical coverage, additional data from Belgium is presented. It has been shown that stalagmite growth, morphology and stable isotope content reflect regional and local climate conditions, with Eemian optimum climate occurring between 125.3 and 117.3 ka. The start the Weichselian is expressed by a stop of growth caused by a drying climate.

Short summary
In this paper we use two climate models to test how Earth’s vegetation responded to changes in climate over the last 120 000 years, looking at warm interglacial climates like today, cold ice-age glacial climates, and intermediate climates. The models agree well with observations from pollen, showing smaller forested areas and larger desert areas during cold periods. Forests store most terrestrial carbon; the terrestrial carbon lost during cold climates was most likely relocated to the oceans.

Short summary
The spring onset and growing season dynamics during the Late Glacial period in the Baltic region were reconstructed using the micro-phenology based on dwarf birch subfossil leaf cuticles. The comparison of pollen- and chironomid-inferred past temperature estimations with spring onset, growth degree day, and plant macrofossil data shows coherent patterns during the cooler Older Dryas and warmer Bølling–Allerød periods but more complicated climate dynamics during the Younger Dryas cold reversal.
