Summary: This study investigates the spatiotemporal patterns of fire activity in China and discusses the possible impacts of climate and human activities on fires. Results show that the changes in Holocene fire activity are closely related to millennial scale moisture variations across China, and intensified human activities over the past 3,000 years may also contribute to the sharp increase in fire activity.

Summary: Long-term ecological studies can provide valuable insights into the resilience of forest ecosystems against past climate change and human disturbances. In this study, a 2200-year-long record of forest development in north-eastern Poland was analyzed using paleobotanical proxies. The findings reveal that the forest remained in a near pristine state until 900 AD, followed by a semi-natural state until 1500 AD. After 1500 AD, coniferous trees became the dominant forest component. The 17th century witnessed massive deforestation and continued human impact, leading to a significant decline in deciduous tree cover. Despite climatic shifts and sustained human activities, Quercus remained a stable forest component until 1500 AD. The study emphasizes the importance of Quercus stability for forest management strategies, as future climate changes are expected to impact forest composition and structure. The results suggest the need for increased abundance of deciduous tree species and reduced conifer cover in the Suwalki region. The study also highlights regional differences in forest development, indicating the influence of local hydrology, geomorphology, and human activity on forest composition.

Summary: The interaction between climate change and disturbances affects forest composition and dynamics. Long-term observations show that climate and disturbances are the main driving forces of forest change. Forests in central Nova Scotia, with relatively low fire frequency, are less influenced by climate variability. Changes in the relative abundances of tree taxa are mainly caused by climate change.

Summary: Climate change is expected to increase fire activity in central Siberia, but little is known about the potential changes in fire regime characteristics and spatial variation in magnitude. This study used a forest landscape model to simulate changes under different climate scenarios, and found that fire activity and intensity increased with climate change. The study also observed a shift in forest composition towards deciduous species in response to increased fire activity.

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: Understanding fire regimes is crucial for effective fire management. By analyzing fire weather and forest fire regimes in China, a zoning system was established based on spatial distribution characteristics. The fire seasons varied based on differences in vegetation, climate, and ignition sources. Human activity was identified as the main cause of fires, particularly in regions with high population density. Fire management strategies should be tailored to each fire regime type to achieve specific management goals.

Summary: Paleoecological records from lake sediments on Pender Island, Canada, were used to reconstruct fire regimes over the past 10,000 years and understand their interaction with climate and forest composition. The study found that the early Holocene was characterized by frequent fires and open-canopy forests dominated by fire-enduring species. However, as temperature and moisture decreased, fire return intervals lengthened and a mixed fire regime of low to moderate-intensity fires emerged. The findings highlight the importance of long-term interactions between vegetation and fire in shaping fire regimes and forest dynamics.

Summary: The role of environmental change in the evolution of cultural traits has been a long-standing topic of debate. Fragmentary archaeological and geoscientific archives, along with insufficient chronological resolution, make it challenging to assess environmental impacts on the evolution of material culture. While repeated co-occurrences of certain features may suggest causality, they are not absolute proof.

Summary: Analysis of the decline of maritime pine forests in the SW Iberian Peninsula reveals complex interactions between climate, fire, grazing, and forest resilience. The decline of pine trees represented a critical transition in SW Iberia, with prolonged drought likely being a key factor leading to tree mortality and the rapid spread of resprouter shrubs. In the face of increasing droughts and other stressors, fire suppression, encroachment of resprouters, and grazing threaten the persistence of Mediterranean forests.

Summary: A coupled pollen-brGDGT paleoclimate reconstruction approach has been tested in the extremely arid environment of mountainous areas from Arid Central Asia to the Mongolian Plateau. The results show millennial and centennial-scale climate oscillations throughout the Late Holocene, with discussions on human historical occupation events and climate system domination. Despite complex climate dynamics, the study suggests a dominant influence of Westerlies/Siberian High cells on central Mongolian climate during the Late Holocene.

Summary: The Sicily region is facing a high risk of drying and desertification due to current warming and land management. A study examined a sediment core from Lake Pergusa to understand the past climatic changes and variability. The findings suggest that the area has experienced wetter and drier periods throughout the Holocene, but the trend of the last 3000 years indicates unprecedented drying, which will be exacerbated by human impact.

Summary: This study focuses on the identification of past slash-and-burn agriculture in soils by analyzing charcoal assemblages. The research reveals that different agricultural practices leave different charcoal signatures in soils, and that soil structure and porosity play a key role in the preservation of the slash-and-burn signal. Additionally, the study demonstrates the potential of combining pedoanthracology with infra-millimetric soil charcoal analysis to track changing slash-and-burn regimes and clarify spatial-temporal patterns of agriculture intensification and extensification in human history.
