Summary: Global warming and changes in land use are major threats to high mountain species. This study evaluated the photosynthetic responses of common paramo species to warming and land use changes. The results showed that the species were not stressed by passive warming, but exhibited stronger photosynthetic response in recovering areas during the dry and warm months. The history of paramo use influenced the species' response to warming, and disturbed soil conditions could lead to a narrower range of physiological response to warming.

Summary: The ongoing climate changes are caused by high levels of anthropogenic CO2 released into the atmosphere in the past decades. Carbon-cutting measures have been proposed to reduce global warming by 2 degrees C, aiming to bring it back to preindustrial levels. One possible option is the use of macroalgae, specifically green seaweed Ulva, to sequester CO2 through photosynthesis. However, there are controversial debates on whether seaweeds can effectively trap CO2 for long periods. Technical and biological gaps need to be addressed before establishing an effective and sustainable seaweed-based mass production for CO2 sequestration. This study explores the potential use of Ulva species in carbon sequestration and discusses their efficient inorganic carbon uptake and fixation traits. It also examines the photosynthetic traits and growth of seaweeds in different cultivation settings, focusing on total carbon budgets for Ulva species from the Israeli Mediterranean Sea. Overall, this work highlights the promising role of Ulva species as a valuable tool to mitigate climate change.

Summary: Melatonin is capable of enhancing drought tolerance in plants by improving antioxidant system and photosynthetic parameters, as well as regulating the synthesis of jasmonic acid and abscisic acid. Exogenous melatonin treatment increases endogenous melatonin content and reduces chlorophyll degrading enzyme activity, leading to higher chlorophyll content and improved drought tolerance in sensitive variety. However, exogenous melatonin treatment has no significant effect on endogenous melatonin content in tolerant variety, indicating that the tolerant variety is already equipped with better drought resistance.

Summary: Global climate change impacts crops and grasslands, but the effects of warming and increased atmospheric CO2 concentrations on the photosynthetic process of tropical forages are not well understood. This study examines the effects of elevated CO2 and warming on the photochemical efficiency of photosystem II and photoprotection strategies of a tropical C4 forage Panicum maximum Jacq. The results show that the photosynthetic system of the plants did not suffer damage, and lipid peroxidation did not increase in response to warming and CO2 enrichment. The study also found that warming increased chlorophyll content and decreased α-tocopherol content.

Summary: The freeze-thaw cycle in permafrost regions is greatly influenced by climate change, but the mechanisms controlling the interannual variability of the start date of permafrost frozen (SOF) are still unclear. Through analyzing long-term satellite data and using various analytical techniques, this study identified climate warming as the major driver of SOF, with the start date of permafrost thawing (SOT) also playing a significant role. Machine learning analysis further revealed the importance of SOT in determining SOF. The study also explored the relationship between SOT and SOF, finding that soil temperature had the strongest impact on this relationship regardless of permafrost type. The findings provide important insights into understanding and predicting SOF variations with future climate change.

Summary: Anthropogenic global change is causing more frequent and intense drought and flood events, leading to imbalances and limitations in soil nutrients. This has become a global challenge for biodiversity conservation and food security. Plants have evolved strategies, such as mycorrhizas and root exudates, to enhance nutrient uptake under environmental stress conditions. However, the effects of these strategies on metal nutrients are still unclear. Therefore, further research is needed to improve nutrient uptake capacity in food crops.

Summary: Coastal wetlands are important for global carbon cycling, but often face challenges from exotic plant invasion. This study investigated the effect of Spartina alterniflora invasion on microbial residues and their contribution to soil organic carbon (SOC) in different coastal wetland ecosystems. The invasion of S. alterniflora had varying impacts on microbial residue carbon accumulation in different wetlands. Overall, it significantly increased microbial residue carbon accumulation in marsh with native Phragmites australis, while showing minor impacts on mangroves with Kandelia candel and Avicennia marina. The response of microbial residues could be attributed to changes in edaphic conditions and plant inputs.

Summary: Among the forms of vitamin E, a-tocopherol is the most distributed compound in plants and plays a crucial role in chloroplasts as an antioxidant. Its ability to eliminate singlet oxygen and modulate lipid peroxidation is of great importance at the cellular level. Additionally, a-tocopherol seems to modulate various physiological processes throughout the whole plant, even those unrelated to redox processes, suggesting nonantioxidant functions.

Summary: Arid and semi-arid forests, including Siberian larch and Siberian spruce, act as important carbon sinks, but the effects of climate warming on their growth and carbon sink dynamics remain uncertain due to the complex interactions between precipitation and temperature. This study found that the interaction between temperature and precipitation plays a key role in regulating xylem phenology of the two dominant tree species, with different responses. Precipitation was shown to drive species-specific response to rising temperatures, indicating its significance in determining growing season length and carbon sink dynamics in arid and semi-arid forests under climate warming.
