Summary: The timing of seed germination in alpine plants is regulated by dormancy, with seeds needing to germinate early in the spring to ensure seedlings can grow to a critical size during the short growing season. Factors such as burial time and dormancy cycle affect the germination timing and season, with seeds remaining dormant until optimal conditions for growth are met.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: The aim of this study was to investigate the seed germination conditions of three Lamiaceae species in Algeria. Two experiments were carried out: ex vitro and in vitro germination tests. In the ex vitro experiment, the combination of different conditions did not have a significant effect on germination success rate (GSR) in all three species. In the in vitro experiment, Thymus algeriensis showed high GSR, while Marrubium vulgare had significantly high GSR with the application of gibberellic acid (GA3) at certain doses and continuous darkness. Rosmarinus officinalis had a very low GSR regardless of the treatments used.

Summary: The study investigated the germination responses of the secondary capitula of Gundelia tournefortii from East Mediterranean mountain populations. Results showed that temperature and plant morphology play a crucial role in controlling seed germination timing, with cold stratification enhancing germination rates. The findings highlight the presence of mechanical and hormonal components of physiological seed dormancy, which can be valuable for plant propagation programs and food security in the East Mediterranean region.

Summary: The research revealed a clear relationship between A. fasciculatum and resident and migratory granivores in the chaparral, as well as the significant role of seed banks in vegetation recovery following fires. The 8-month seed rain duration with over 1 million seeds per square meter, multiple seed predators including passerines and rodents, and the potential role of native ants in seed dispersal were documented. The study also showed that a 39-year-old stand had higher germination rates than stands of different ages, emphasizing the importance of seed banks in ensuring resilience.

Summary: The ability of plants to form persistent seed banks is strongly associated with naturalisation and invasiveness, while traits like seed bank densities play a relatively weaker role. Knowledge of seed persistence can enhance our predictive ability for global naturalisation and invasiveness.

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: The study of seed ecology of poisonous plants is essential for providing theoretical support and recommendations for the control of poisonous plants in grasslands. Commonalities in the seed ecology of different poisonous plants include the persistence and surface aggregation of soil seed banks, as well as primary dispersal by wind and animals.

Summary: This research examined the seed dormancy, germination, and soil seed bank dynamics of Eruca sativa, a versatile cruciferous species. The study found that E. sativa seeds can germinate in a wide temperature range and exhibit non-deep physiological dormancy at maturity. The germination of seeds is sensitive to water and salinity stress. When buried in soil, the seeds form a persistent soil seed bank, but emergence is hindered when buried deeper than 5 cm. This species' germination characteristics allow it to adapt to the harsh low-temperature climate of the Qinghai-Tibet Plateau.

Summary: This study investigates the applicability of the seed size-seed number allocation model in long-term persistent soil seed banks. The results show a significant negative relationship between seed bank density and fruit or seed size in Arctostaphylos species. This is attributed to seed predation and postfire seedling establishment, rather than an issue of trade-off between size and number.

Summary: This study presents a comparative analysis of riparian vegetation dominated by Alnus glutinosa in Italy and Tyrrhenian islands, based on literature data and unpublished releves. A total of 456 phytosociological releves were analyzed using clustering and ordination methods. The study identified 18 A. glutinosa-riparian wood communities, including two new associations and one new subassociation. The classification of the releves showed two main vegetation groups: Osmundo-Alnion alliance and Ligustro vulgaris-Alnion glutinosae alliance.

Summary: The 'metalliferous ring' of Iglesiente in Italy, which was once the most important mining district for centuries, has faced a decline in mining activities. Alternative management strategies were proposed to address issues of unemployment and environmental pollution. The study focused on the coastal section of the mining district and evaluated the vegetation development and conservation value of the area. The analysis of 96 vegetation samples revealed three main plant assemblages with 227 vascular plant species and 18 endemics. Herbivory was found to be the most influential variable affecting species composition, negatively impacting species richness and diversity while positively affecting evenness. Elevation and debris/rock flow degree were also influential variables. Other factors influencing vegetation included soil grain size and years of mining inactivity. The identified plant communities, especially those with perennial herbs and small shrubs, can be used for phytostabilization and remediation, providing surrogate habitats for endemic plants.

Summary: The Mediterranean Basin is a hotspot for plant diversity and is highly vulnerable to climate change and human activities. There has been a significant increase in practical conservation actions, particularly plant translocations, to prevent species extinction and improve their conservation status. However, there is a lack of scientific documentation on plant translocations compared to the number of actions carried out.

Summary: The study analyzed the impact of ecological and anthropic factors on the recruitment of the common yew in Sardinia, Italy. Through research and field surveys, 232 sites were discovered where yew grows in Sardinia. The results showed that shrub cover and soil moisture positively correlated with yew recruitment, while browsing from livestock and wild animals had a negative effect.

Summary: The objective of this study was to evaluate the morphophysiological and biochemical changes in Enterolobium contortisiliquum seedlings subjected to water and salt stresses. The results showed that both salt and water stresses compromised the development of E. contortisiliquum seedlings, with the damage becoming more severe from an electrical conductivity of irrigation water of 2 dS m-1 and four days without irrigation. The survival mechanism of E. contortisiliquum to abiotic stresses involves reduction in growth and quality of seedlings, accompanied by the activation of biochemical defense mechanisms of the species.
