Summary: This study investigated a former mangrove wetland in Peninsular Malaysia and produced new sea-level index points (SLIPs). The study re-analyzed modern vegetation and pollen results to establish the relationship between vegetation zones and tidal levels for estimating indicative meanings for the SLIPs. The results showed a gradual rise and fall of relative sea-level in the middle-to-late Holocene, supporting the hypothesis of additional ice melting during that time. Additionally, SLIPs from the east coast were systematically lower in elevation than those from the west coast, indicating the existence of continental levering during the Holocene.

Summary: Studying the interactions between paleoecology and climate variations in semi-arid areas, such as the Songnen grasslands in northeastern China, provides insights into how future vegetation changes and hydrological variations may impact semi-arid ecosystems. This study presents a high resolution palaeoecological dataset covering the past 7300 years and reveals the dynamics of vegetation and water levels in the Dabusu peatlands. By comparing these features with regional climate change, the study suggests that East Asian Summer Monsoon circulations might be the main driving force controlling the regional paleovegetation dynamics and hydrological variations.

Summary: A multiproxy analysis of sediment core from Glukhoye Lake in the southern Kuril Islands reveals the basin's history mainly reflects local coastal dynamics, unaffected by Archipelago-wide sea level changes. Vegetation changes indicate a gradual cooling from the Holocene thermal maximum to present, with Picea and Abies pollen suggesting slightly cooler conditions between 2.3 and 1.1 cal. ka BP. The difficulty in developing accurate age models due to multiple depositional environments poses a significant challenge in understanding the Archipelago's vegetation and climate histories.

Summary: This study reconstructs the past plant cover changes in the Songnen grasslands in northeastern China and examines the relative importance of climate, fire, and human activity on vegetation dynamics. Results show that vegetation evolution was mainly driven by East Asia Summer Monsoon and related precipitation variations, while also affected by fire frequency and human activity. Fire events can alter vegetation stability and facilitate rapid responses to climate changes, while human activity has limited influence on vegetation changes.

Summary: This paper investigates the groundwater characteristics and chemical composition in coastal areas. The results show that the groundwater is neutral to weakly alkaline and the chemical types are mainly chloride-sulfate and sulfate-chloride-calcium-magnesium. The hydrochemistry is mainly influenced by rock weathering and evaporative concentration. A current situation map of groundwater quality in Laoshan District is obtained using GIS technology and the kriging spatial interpolation method. The research is significant for the utilization of groundwater resources and the management of seawater intrusion.

Summary: This paper presents a high-resolution palynological record from the Lake Victoria basin, showing the ecological successions and landscape transformations in tropical East Africa from 16,600 to 9,000 cal yr BP. The study demonstrates the dynamic response of African tropical ecosystems to long-term temperature and humidity variations during this period.

Summary: Understanding past climate and vegetation changes is crucial in assessing the impact of climate and human activity on regional vegetation compositions. Research shows that subtropical East Asia has experienced a shift from evergreen broad-leaved forests to more open landscapes since the late Holocene, which is attributed to increased human activities during that period.

Summary: This study isolated and identified Escherichia coli from pigeons in Qingdao to determine their susceptibility to 18 antibiotics. The results showed that the resistance to some antibiotics and the multi-drug resistance of Escherichia coli from meat pigeons were higher than those from homing and ornamental pigeons.

Summary: The rapid expansion of the Pearl River Delta Plain in recent millennia was primarily attributed to intensified human activities rather than changes in climate variables, as indicated by a study of a marine core from the northern South China Sea. The findings suggest that human activities significantly influence the formation and development of deltas, highlighting the potential impact of ongoing global warming and human activities on deltas worldwide.

Summary: The study revises the existing stratigraphic records in central and eastern Fennoscandia, revealing a more complete and extended palaeoenvironmental history than previously thought. The findings suggest the presence of birch forest tundra during certain warm intervals, challenging the previous assumption of boreal pine forests in the region. Additional research is needed to further explore the warm periods and sedimentary records during the Middle Weichselian in the studied area.

Summary: This study examines the correlation between hydroclimatic change and vegetation history in the Xixi Basin, eastern China, during the late Pleistocene to early Holocene. The analysis reveals warm/dry and cold/wet climatic patterns that are consistent with palaeoclimatic records in the middle Yangtze region. These patterns are related to the migration of the Meiyu Front modulated by the El Nino-Southern Oscillation (ENSO) activities.

Summary: In this study, we calculated the rates of vegetation composition changes (RoCs) in the Central Arid Zone of Asia during the Holocene using 46 pollen records. We also examined the importance of six drivers (temperature, precipitation, CO2 concentration, fire, pasture, and cropland activities) using Structural Equation Modeling (SEM). The results showed that RoCs at high elevations had high values in the early Holocene, decreased to their lowest values at -6000 cal. yr BP, gradually increased between -6000 and -3000 cal. yr BP, abruptly decreased in the past 3000 years, and then resumed an upward trend. RoCs at lower elevations experienced a steady acceleration throughout the Holocene, possibly due to climate cooling and wetting, as well as intensified fire activities.

Summary: This study presents the first continuous pollen record for the Iberian Pyrenees during the Late Glacial-Early Holocene period. The aims of the study were to establish a chronostratigraphic correlation framework, understand the relationships between vegetation shifts, climatic changes, and fire, and obtain a regional picture of the vegetation during this period. The results revealed four vegetation types and showed wetter climates during the Younger Dryas, challenging previous assumptions of arid conditions. The study also found an increase in fire incidence during the Early Holocene. The findings were compared with other pollen records in the Pyrenean range and surrounding lowlands.

Summary: This study explores the impact of climate change and human activity on the ecological border and societies. By analyzing sediment cores from a mire in Ukraine, it is found that fluctuations in the southern tree line correspond to changes in cultural economies. The spread of forests and increased moisture have contributed to the transition from nomadism to agriculture.
