“…In general, the PqPann fluctuations matched temperature anomaly fluctuations in northeast China 7 (Fig. 4a, f), whereas the time-series variability data of δ 18 O for BN-1 was comparable to the time series solar irradiance 49 (Fig. 4e), resulting in BN-1 leads with lags in the variation of PqPann.…”

“…4b). The variability and trend of the PqPann and ANNs reconstruction of South Korea (GG19-2-1 and SOJ-2 18 ) are comparable to those of northeast China (Lakes Jingpo 32 and Silhailongwan 27 ), but the Korean PqPann amplitudes (655-1530 mm/yr) are higher than those in China (644-949 mm/yr) ( Fig. 4a), despite the almost equivalent rainfall duration (Fig.…”

“…Therefore, the KP is much closer to the EASM rainband than is northeast China, so the KP is highly affected by rainfall forcing of the EASM rainband. In comparison with BN-1 9 of South Korea, δ 18 O of HC 33 for southeastern China had small values, but a higher amplitude ( Fig. 4c, d), indicating greater rainfall intensity in southeastern China due to its location within the EASM rainband area (Fig.…”

“…The time series of the PqPann GG19-2-1 and δ 18 O data for BN-1 9 were compared using 100-year Butterworth low-pass filtering and cross-correlation analysis. Remarkably, the medians of the most highly significant crosscorrelations between the two datasets revealed similar variability, with lags of 25-50 and 50-100 years during the MWP and LIA, respectively (Fig.…”

“…Changes in precipitation on the KP over the past 1300 years were reconstructed, including through pollen analysis and covering the hiatus period. When the same statistical technique was applied to the reconstructed pollen-based precipitation and δ 18 O of speleothem data, we found time-series lags between biotic and abiotic responses to rainfall, although they showed similar fluctuation trends. The time-series lags differed between the Medieval Warm Period (MWP) and Little Ice Age (LIA).…”

East Asian summer monsoon (EASM)-driven rapid hydroclimatic variation is a crucial factor with major socioeconomic impacts. Nevertheless, decadal- to centennial-scale EASM variability over the last two millennia is still poorly understood. Pollen-based quantitative annual precipitation (PqPann) and annual precipitation reconstructed by artificial neural networks (ANNs) for the period 650–1940 CE were reconstructed from a paleo-reservoir in South Korea. ANNs reconstruction was performed to compensate for a hiatus section. On a decadal timescale, 10 high-precipitation periods were identified, and PqPann and ANNs reconstructions were comparable to local instrumental rainfall and historic drought records. Biotic lags to rapid climatic changes ranging from 25 to 100 years were recognized by asynchronous pollen and speleothem responses to precipitation. We suggest that PqPann-based decadal- to centennial-scale climatic change reconstruction should take biotic lags into account, although the lags can be ignored on the millennial scale. The position of the EASM rainband influenced rainfall magnitude.

Climatic fluctuations and geological events since the LGM are believed to have significantly impacted the population size, distribution, and mobility of many species that we observe today. In this paper, we determined the processes driving the phylogeographic structure of the Korean endemic white forsythia by combining the use of genome‐wide SNPs and predicting paleoclimatic habitats during the LGM (21 kya), Early Holocene (10 kya), Mid‐Holocene (6 kya), and Late Holocene (3 kya). Using a maximum of 1897 SNPs retrieved from 124 samples across nine wild populations, five environmental predictors, and the species' natural occurrence records, we aimed to infer the species' demographic history and reconstruct its possible paleodistributions with the use of approximate Bayesian computation and ecological niche models, respectively. Under this integrated framework, we found strong evidence for patterns of range shift and expansion, and population divergence events from the onset of the Holocene, resulting in the formation of its five distinct genetic units. The most highly supported model inferred that after the split of an ancestral population into the southern group and a larger central metapopulation lineage, the latter gave rise to the eastern and northern clusters, before finally dividing into two sub‐central groups. While the use of molecular data allowed us to identify and refine the (phylo)genetic relationships of the species' lineages and populations, the use of ecological data helped us infer a past LGM refugium and the directions of post‐glacial range dynamics. The time frames of these demographic events were shown to be congruent with climatic and geological events that affected the central Korean Peninsula during these periods. These findings gave us a better understanding of the consequences of past spatiotemporal factors that may have resulted in the current fragmented population distribution of this endangered plant.

Climate and land use change can profoundly impact the provision of ecosystem services (ES) over time, particularly in the landscape of open fields along with growing urbanization and rising demand for space, food and energy. Policymakers are keen on knowing the combined effects of climate and land use change on ESs as a critical issue in human well-being. However, deep knowledge of how to identify these relationships is still lacking. This research aims to undertake a comprehensive assessment of soil- and water-related ES, and improvement in understanding how they are affected by climate and land use change. We applied the Integrated Valuation of Ecosystem Services and Trade-offs model for four ES (soil retention, nutrient delivery ratio, carbon storage, and water yield) for the years 2000 and 2018 in the Nitra region, Slovakia. We investigated the spatial and temporal changes in ES provision and determined the hotspots and coldspots of multiple ES. We found that soil retention, water yield, and carbon storage display a rising trend while the nutrient delivery ratio showed a decreasing trend over the past 18 years. Although all the mentioned services mainly attributed to land use change, the relative contribution of climate change was not deniable. Forests in the north and east and distributed urbanization and agriculture are the hotspots and coldspots for all ESs, respectively. Our results, in terms of determining the relative importance of land use and climate change and identifying the sensitive areas of ES provision, provide a scientific basis for ecosystem conservation and management priority setting at the local and regional levels.
