Summary: This research presents the paleoenvironmental evolution of a drained lake at the Lousoi plateau (northern Peloponnese) for the past 10,000 years, based on the analysis of a 7 m depth core. The study reveals that the lake experienced increased water levels and wet climatic conditions from 10,900 to 7700 cal BP, with a dry pulse at 9400 cal BP. The transition to more shallow waters and a more oxygenated phase occurred at 8200 cal BP. In the Late Holocene period, the lake was highly affected by pedogenic processes, making it difficult to distinguish paleoclimatic/paleoenvironmental signals.

Summary: This paper reports on the long-term debris-flow activity in the Tsivlos landslide area in Greece, finding that debris-flow activity has been most frequent since 2014, with a link to increased extreme precipitation events. Analysis of aerial images confirmed the shift of active channels and debris-flow fans, mainly due to the occurrence of collapsed slopes. The study suggests the need for continuous monitoring and field research to prevent future debris flow hazards.

Summary: The Kotychi Lagoon, part of the wider area of Strofylia Wetlands National Park and Protected Areas of Western Peloponnese in Greece, has been protected since 1971 and classified as a Natura 2000 area. This study used remote sensing techniques to estimate the water surface evolution of the lagoon from 1945 to 2016 and evaluated its ecological and environmental status. High-resolution aerial photos, orthomosaics, and satellite images were used, and linear regression rates were calculated. In-situ measurements and sample analysis were conducted to monitor environmental and ecological parameters. The results showed shrinkage of the lagoon's water surface, particularly in the northeastern and southern parts, with rates of 17.75 and 6.46 m/year, respectively. The ecological status was determined to be poor. Remote sensing techniques and in-situ analyses highlighted the ecological problems of the Kotychi Lagoon. Restorative measures are needed to improve its ecological status.

Summary: Through the study of high-resolution lake sediment records from northern China, it is found that the rise of the Earth's crust has led to significant changes in lake temperatures, which corresponds to the increase in mid-Holocene warm-season temperatures in China. Combined with reliable pollen-inferred precipitation data from northern China, it can be independently verified that the East Asian thermal and summer monsoon reached their maxima synchronously during the mid-Holocene, indicating that the interaction between heat and temperature is the most probable mechanism for the East Asian summer monsoon throughout the Holocene.

Summary: The aim of this study was to investigate the usability of artificial neural networks (ANNs) for estimating reference evapotranspiration (ETo) in the Peloponnese Peninsula, Greece. The results showed that ANNs can be a good predictive model for ETo, even with a simple architecture. The most influential factors for ETo were found to be the mean temperature (Tmean) and wind speed (u(2)).

Summary: As dynamic processes in the Earth's mantle stretch and thin the African plate, broad plateaus interrupted by deep valleys and flanking mountains have formed. These movements occur concurrent with global climate changes. Together, they modulate eastern Africa's habitats for early humans and other organisms. The uplift of the plateau in Ethiopia, which initiated around 30 million years ago, played a role in the evolution of humans. The sedimentary sequences in rift basins record the history of human evolution and the complex interplay between climate change, uplift, volcanism, and faulting in equatorial Africa. The lake shorelines and hydrothermal systems provided oases for early hunter-gatherers, and the topography of the faulted landscape may have served as refugia.

Summary: The Achaea and Corinth regions in the northern Peloponnese are well-known for their archaeological record and the important role of ceramic production in local social and economic evolution. Through compositional and technological analysis of clayey raw materials, distinct regional variations were identified, influencing the performance characteristics of the materials for ceramic production. Despite the lack of significant differences in clay deposits across the areas, improvements were needed for them to be suitable for ceramic artifact production.

Summary: This study presents detailed environmental and climate records from a lake sequence of MIS 5a age in Sokli basin in northern Finland, providing insights into regional vegetation development and climate changes during this period. Pollen and plant fossil data indicate typical interglacial vegetation development during the early half of MIS 5a, while reconstructions of July temperatures based on pollen assemblages are influenced by local pollen from the lake's littoral zone. However, plant fossil data suggest that summer temperatures reached present-day values during the upper part of the lake sequence.

Summary: This study reconstructs the vegetation of the Argive Plain in Greece for the past 5000 years and shows the significant impact of human activities on the environment. From the Early to Late Bronze Age, the landscape changed due to cultivation and the presence of palatial centers. From the Archaic period onwards, human pressure and drought caused landscape instability, leading to vegetation degradation.

Summary: This study reconstructs the Holocene shore displacement of the Vastervik-Gamlebyviken area in Sweden and provides evidence for the transgressions of the Littorina Sea. Sediment cores were analyzed to determine the sea level changes and the results show an initial transgression at 8.5 ka BP, a rise in sea level between 8.0 and 7.5 ka BP, and a highstand at around 22 m a.s.l. between 7.5 and 6.2 ka BP. These findings are consistent with the Littorina Sea transgressions in southern Sweden and the deglaciation of North America.

Summary: This study analyzed fossil diatoms and litho-stratigraphic changes in the Guern El Loulailet depressions in the northern Algerian Sahara. The findings provide evidence for two Holocene lacustrine episodes related to the African Humid Period. The study suggests that the main drivers of the African Humid Period were the northward shift of the Intertropical Convergence Zone (ITCZ) and expansion of summer monsoonal rains.

Summary: Naxos in the Greek Cyclades islands is an important example of polymetamorphism that has recorded different metamorphic events in different parts of the island. A new approach using electron probe microanalyzer (EPMA) characterization of white mica (WM) and Ar-39-Ar-40-Rb-Sr multichronometry is proposed to study these events. The study reveals the presence of five different generations of WM and provides insights into the ages and metamorphic history of the island. This approach has potential applications in reconstructing polyphase metamorphic histories worldwide.
