Summary: The study reveals thresholds for physiological viability and vegetation- climate feedbacks in Earth's tropical forests during Late Paleozoic Ice Age, leading to turnover of plant species. The shift to more drought-tolerant plants provided ecological advantages, but their impact on climate was limited by aridity and vegetation density. Atmospheric pCO2 has a larger effect on physiological functioning than pO2 in these extinct plant species.

Summary: The discovery of well-preserved fossils with recurved cupules from the Early Cretaceous in Inner Mongolia, China, suggests that these plants are fundamentally comparable to angiosperms in their structure, specifically the second integument of the ovule. This finding provides insight into the origin of angiosperms and will guide future research in seed plant phylogenetics.

Summary: Based on cluster and correspondence analysis, Late Paleozoic trilobites exhibit varying degrees of provincialism and cosmopolitanism over time. These distributional changes are shown to coincide temporally with the closure of the Rheic Ocean and the onset and decline of the Late Paleozoic Ice Age. The trilobite faunas of different epochs and geological periods also show differences in distribution and ecological tendencies.

Summary: This paper presents a comprehensive data set on sodium carbonate evaporites found in the Fengcheng Formation in northwestern China, offering insights into their mineralogy, age, and formation processes. The study suggests that these deposits were formed in extensional grabens hosting hypersaline lakes, which were influenced by coeval volcanic activity.

Summary: The Tarim basin is a complex sedimentary basin that has undergone multiple and polycyclic tectonic movements. Understanding its prototype basin and tectono-paleogeographic evolution is crucial for understanding the tectonic systems and hydrocarbon exploration. This paper provides maps and illustrations to depict the tectonic and paleogeographic features of the Tarim basin during the Late Paleozoic.

Summary: The tectonic setting of South China during the late Paleozoic is crucial for understanding the geodynamics of the eastern margin of the Pangea supercontinent. By studying the late Carboniferous siliciclastic rocks in southeast South China, it is revealed that there was episodic lithospheric delamination and subduction of the paleo-Pacific plate beneath the South China Block in the late Paleozoic.

Summary: The study of coral fossils from the Shiqiantan Formation (310 Ma) in China has revealed that the growth line increments of a single coral in the area are influenced by the duration of sunlight exposure. Additionally, the daily increment of growth lines, caused by calcium carbonate deposition, follows an unusual bimodal curve. This study indicates that Shiqiantan experienced distinct seasonal changes during the Late Carboniferous period, with a climate similar to that of modern North China. The findings presented in this paper provide important insights into the study of Late Paleozoic climate and the ancient obliquity of the ecliptic.

Summary: This study provides evidence for the involvement of continental aquifers in the global water cycle during icehouse episodes at the million-year scale. The analysis of lacustrine sedimentary sequences and paleoclimate simulations reveals the influence of groundwater aquifers on long-period obliquity cycles and sea-level fluctuations during the late Paleozoic ice age.

Summary: The functional response of plant communities to disturbance is determined by changes in environmental conditions and evolutionary history of species. Direct manipulations of repeated disturbances within ecosystems are rare. We studied the effects of 41 years of manipulated fire on plant leaf economics and found that greater fire frequencies created a high-light and low-nitrogen environment, resulting in more diverse communities with denser leaves and lower foliar nitrogen content. The trait-fire coupling was influenced by both intraspecific trait-fire correlations and interspecific trait differences, with turnover among specific clades playing a role in shaping trait-fire trends.

Summary: The passage discusses the evolution of sediment-dispersal networks from the Late Mississippian to the middle Permian in western equatorial Pangea, influenced by climate, eustasy, and the late Paleozoic orogenic system. Different geological events, such as uplifts, basins, and river systems, contributed to the transportation and distribution of sediment across the region, shaping the landscape over time.

Summary: By analyzing new geochronological, geochemical, and isotopic data, this study sheds light on the characteristics and tectonic evolution of the ophiolitic rocks in the Wandashan accretionary complex. It suggests that the Paleo-Pacific Plate began subduction in the Early Permian, forming a back-arc basin that widened from 280 to 232 Ma and eventually closed to create the Yuejinshan complex.

Summary: This study utilizes anatomical analysis of fossils from Vancouver Island, Canada, to support the development of a whole plant concept for the Eocene species of Gleichenia and provide data for the first organismal concept of an extinct species of Gleichenia from the Cenozoic fossil record. The findings suggest that the characteristics of the Gleicheniaceae family were present during the Cretaceous and Paleogene periods, with modern species well-established and diversifying.

Summary: This study presents a palaeoecological reinvestigation from the Kardashynskyi mire in southern Ukraine, reconstructing the vegetation dynamics, fire history, and land use for the past 8300 years. The results show that both climate and human activities have driven the vegetation changes, and the remaining special vegetation types are severely threatened under current conditions.

Summary: The relationships between woody vegetation cover and fire, climate, herbivory, and human activities in African savanna ecosystems are complex. Fire suppression policies implemented in a national park in northeast Namibia from 1888 to 2005 did not lead to noticeable decreases in fire or enhanced tree recruitment, suggesting that fire occurrence in savanna ecosystems is more closely linked to climate than management. Fire management should adapt to rainfall variability and integrate customs of early dry season burning.
