Summary: Understanding the germination pattern and seed longevity of Echinochloa colona in field conditions is crucial for effective weed management. The study found that the populations of E. colona exhibited innate dormancy, with some seeds capable of germinating in the next season. The research also indicated that seed persistence and germination patterns of E. colona can vary with different soil and agro-climatic conditions.

Summary: Temperature and salinity have significant effects on seed germination, but the sensitivity to these factors varies among plant species. Festuca arundinacea is less sensitive to temperature and salinity, while Bromus inermis and Elymus breviaristatus are sensitive to high salinity levels. These findings can enhance our understanding of seed germination in saline soils under changing climate conditions.

Summary: Desiccation tolerance is a key adaptation feature of photoautotrophic organisms in terrestrial habitats. Vascular plants have developed complex anatomy structures and molecular mechanisms to maintain cell hydration, with different genes encoding mechanisms playing varying roles in different stages of plant evolution.Mechanisms behind desiccation tolerance include LEA proteins, sHSP, oligosaccharides, and antioxidants, activated during late seed maturation stage. Regulation is controlled by abscisic acid and protein DOG1, along with a network of transcription factors and epigenetic regulation.

Summary: The experiment studied the longevity of seeds in soil by burying glass bottles filled with seeds and sand for over a century. The results showed that a significant percentage of Verbascum seeds can still germinate after 141 years. This long-term experiment provides valuable insights into the viability of seeds in natural soil conditions.

Summary: This study examined the seed morphology, superficial ornamentation, and germination characteristics of eight wild tulip species native to China. The results showed diverse seed shapes, sizes, colors, weights, and superficial ornamentation. The morphology of the seed was related to germination, and factors such as embryo length, embryo/seed length ratio, seed coat color, temperature, and gibberellin concentration influenced germination.

Summary: Understanding responsible functional traits is important for managing invasive species. Seed traits and germination strategies of nine invasive species were studied. Results showed interspecific variation in germination percentage and temperature affects germination. Variability in germination requirements may explain species coexistence and invasion ability.

Summary: The research focused on the seed germination of two alien plant species, Phytolacca americana and P. acinosa, in Europe. Both species were found to have different levels of invasive success, with P. americana exhibiting better germination and fruit ripening on cut plants compared to P. acinosa. The study suggests that removing all fruiting plants from the eradication site is crucial regardless of the fruit development stage.

Summary: This research is the first to study the seed germination of two varieties of the endangered medicinal species Anacyclus pyrethrum. The study reveals that the seeds exhibit strong dormancy characteristics, which can be broken by cold scarification and chemical treatment. Additionally, long-term storage in wet cold conditions decreases seed viability, while long-term storage at low temperatures induces dormancy.

Summary: Global change and environmental pollution have raised the alarm for ecologists about the significant threat of multi-stress interactions to plant growth stages. This research focused on the effects of sand burial, salinity, drought, and their interactions on the germination of Sophora alopecuroides L. seeds. The results showed that sand burial and salinity stress had significant effects on seed germination, while drought stress had no significant effect, but the interaction of the three stresses had a significant effect. The study also found that sand burial stress was the most limiting factor for seed germination, and moderate increase in soil saline-alkali content and soil moisture could improve germination ability.

Summary: This study demonstrates that invasive plant Ambrosia artemisiifolia adapts its seed traits in response to climate variations along latitudes and longitudes. Germination time is delayed with increasing latitude and longitude, while germination rate shows a reversed pattern. Temperature is identified as the dominant driver of the variability in seed traits and germination.

Summary: The formation of soil seed banks is crucial for the survival of desert plant species. Stored seeds show higher germination percentages and changed light requirement for germination compared to fresh seeds. Additionally, stored seeds can persist in soil seed banks, offering great potential for maintaining and restoring desert ecosystems.

Summary: This study investigated the mechanisms underlying interspecific differences in seed thermotolerance in desert Cactaceae species. It was found that enhanced dry seed thermotolerance is realized through enhanced recovery from heat stress during imbibition, particularly during critical stages in the plant life cycle. The study highlights the importance of heat-responsive gene expression patterns in contributing to higher dry seed thermotolerance in extremophile Cactaceae species.

Summary: This study investigates the changes in the atmospheric electric field (Ez) during foggy conditions in the hyperarid region of the United Arab Emirates. The results show that as fog persists, Ez becomes more variable due to the absorption and redistribution of charges by the fog, which alters the ion balance and affects electrical conductivity in the atmosphere.

Summary: This study investigated whether the prey of striped hyenas has adapted to the change in the natural environment caused by human activities, particularly artificial light at night (ALAN). The results showed that ALAN had no impact on the diet or den distribution of the hyenas in central Israel. The study also found that domestic animals were the most common prey, and there were also some vegetative species in their diet. Overall, the feeding behavior of striped hyenas is influenced by geographical region, habitat, and human activities.

Summary: This study evaluated the IMERG satellite-based precipitation product in the Fars province of Iran using daily rain gauges as reference data. The results showed that the product tends to overestimate light rainfall and underestimate heavy rainfall, with the best performance in the 40-80 mm/day range. The accuracy of the product varies by month and is less biased in months with milder temperatures. Additionally, there was a higher correlation in mid-elevated areas, positive bias in low-elevated areas, and negative bias in high-elevated areas. Longer time scales showed considerable improvement in the IMERG estimates.
