Summary: While extreme weather and climate events have been studied for several decades, analysis of compound events has only begun in recent years. The study found that many severe flooding events in Tasmania do not coincide with the highest rainfall days. A method was developed using climate data and models to examine compound rainfall events from 1961 to 2100. The findings showed a decrease in the number of compound rainfall events in the Tasmanian catchments studied, with an increase in intensity in some areas.

Summary: Compared to arid regions, forests in humid regions are more susceptible to drought due to their lack of adaptation to water stress. This study investigated the xylem structures and functions of two Cupressaceae species in a mesic garden, revealing differences in hydraulic function and anatomical structure between branches and roots. The results showed no trade-off in anatomical structure and suggested that the two species exhibit low efficiency and low safety in xylem. The study also suggested that the structural basis for a safety-efficiency trade-off does not exist in these species.

Summary: Identifying refugia, where species can survive during unsuitable climate, is crucial for conservation in a warming world. Conservation paleobiology combines fossil records with modeling to locate refugia and understand vulnerability to climate change. A case study in Acadia National Park demonstrates the importance of using plant macrofossils and pollen to update vulnerability assessments and locate potential future refugia.

Summary: A study on fossil records suggests that Ailanthus has been distributed in low latitude regions since the middle Eocene. It is believed that Ailanthus originated from the Indian subcontinent and quickly spread to East Asia and western North America following the India-Eurasia collision. With the global cooling, Ailanthus gradually disappeared in the mid-high latitudes and may have continued to spread southward to northern Australia.

Summary: This study presents high-resolution palynological data from Mogan Lake in the Golbasi Basin of central Anatolia, Turkey, providing insights into the paleobotanical, paleoclimatological, and paleoenvironmental records of the region over the last ca. 3100 years. The vegetation changes in the Ankara region are primarily driven by climate, with influences from both natural and human-induced factors.

Summary: A new apionine genus and species, Diselmobius lechi, was discovered in Tasmania and compared with other related species in Australia and New Zealand. Although the tribal placement of Diselmobius remains uncertain due to a lack of male characters, it represents an important addition to the fauna of Australia.

Summary: This paper discusses how to deal with the unbalanced archival remains of climate knowledge production in Hobart Observatory and other locations, proposing a comprehensive methodology. Through the study, it is revealed that gender relations played a significant role in shaping how atmospheric knowledge was produced and utilized by historical actors in colonial Tasmania.

Summary: Spring-fed fens with calcareous substrates are unique biodiversity islands hosting endangered plants. Long-term paleoecological studies provide insights into wetland ecosystem development and preservation, highlighting the importance of protection measures in the face of human activities and climate change.

Summary: The 2019/2020 southeast Australian fires posed a significant threat to the endemic vegetation groups, especially the Tasmanian montane rainforest. However, little is known about the impacts of fire and decline in montane rainforest on aquatic ecosystems in the region. This study investigates the effects of repeat fires and decline in montane rainforest species on the aquatic ecosystem of Lake Osborne, Tasmania, Australia over a period of 6500 years using a palaeoecological approach. The results suggest that fire disturbance leads to the decline of montane rainforest, increased erosion, and higher aquatic productivity and conductivity.

Summary: Somatic embryogenesis in conifers and Gnetales is a complex process with multiple steps, including the development of proembryogenic cell masses, histodifferentiation, somatic embryo development, maturation, desiccation, and plant regeneration. Our understanding of this process is mainly based on studies using Pinaceae species as a model, and the evolutionary relationship between conifers is still unclear. This review aims to provide a comprehensive overview of the current knowledge on somatic embryogenesis in conifers and Gnetales, highlighting similarities and current challenges. Further research on this morphogenetic pathway may reveal common points between these species and improve the success of somatic embryogenesis.

Summary: The study demonstrates significant changes in vegetation and fire dynamics around Lake Svityaz during the Holocene. A boreal forest was established around 13,450 years ago, followed by the expansion of temperate tree species. Fire activity was highest during the Early Holocene, while human impact on vegetation began to increase around 3,400 years ago.

Summary: Managing fire in the changing climate of Tasmania is crucial, with eucalyptus species playing a significant role in fuel load and flammability. Future projections suggest notable changes in the distribution of these important fuel species, highlighting the need for adaptive fire management strategies. Different responses of E. delegatensis and E. obliqua to changing climates indicate the complexity of the impacts, requiring further research for understanding the mechanisms driving these changes.

Summary: Cupressaceae fossil tree stumps from the Oligocene of southwestern China were found to contain abundant quartz-petrified damage traces, and the fossils also revealed arthropods and fungus, filling a gap in the fossil records for insect herbivory in this region. The disappearance of Taxodium supports the changes in the environment at that time.

Summary: This study analyzes sediment samples from Bjerkreim, SW Norway, providing detailed information about the late-glacial environments. The analysis includes pollen, plant macrofossils, chironomids, paleomagnetism, elements, volcanic ash, and loss-on-ignition. The study reveals the dominance of pioneer vegetation on unstable mineral soils during the pre-Bolling period, the establishment of dwarf shrubs and snow beds during the Bolling warming, and the expansion of early Betula/Populus-forests and later Corylus forests during the early Holocene warming.

Summary: Proxy records from the late Quaternary provide insights into climate variability on extended time scales. A study on ancient Douglas fir logs in Oregon, USA, reveals the response of tree growth to climate on annual and decadal scales. The findings suggest that the growth of Douglas fir trees was sensitive to moisture and ecological disturbances, and their tree-ring records showed both low and high-frequency cyclic behavior. Oxygen isotopes may track moisture, while carbon isotopes may track temperature or sunlight.

Summary: The study focused on the structure of phylloclades and true leaves in Phyllocladus, with emphasis on function, ecology, and evolution. It was found that only in the earliest ontogenetic stages do true, needle leaves develop, while mature individuals have entire short shoot systems that increase their photosynthetic area. These adaptations were likely necessary due to competition from angiosperm forests in the Southern Hemisphere.
