Summary: Litter cover has a negative effect on seedling emergence and survival, but has no significant effect on root, leaf, and total biomass. It has a positive effect on stem biomass and seedling height. Thick litter layers have a greater impact on seedling emergence, survival, and total biomass. Broadleaf litter cover has a stronger negative effect on seedling emergence and total biomass than needle litter.

Summary: This study found that seed predation in tallgrass prairie restorations varies significantly throughout the year, peaking in late fall to early winter. However, seed predators consumed significantly fewer seeds when plant litter was removed following fall burn and fall mow treatments. These management techniques can reduce seed predation losses, emphasizing the importance of management decisions in grassland restorations.

Summary: This study demonstrates that there is no trade-off between seed persistence and seedling emergence from the soil seed bank. Physically dormant seeds are more persistent but exhibit lower emergence. Monocarpic species have both higher persistence and emergence than polycarpic species. Seed mass has a marginal effect on persistence, while emergence increases nearly twofold from the smallest to the largest seeds.

Summary: Grazing negatively affects the seed rain, soil seed bank, and seedling recruitment of Nassella tenuis, especially in interpatch areas. Soil compaction, seed removal by wind, and increased cover of annual species decrease the soil seed bank of N. tenuis, particularly in microsites exposed to the prevailing wind direction. However, there is no difference in seed rain and soil seed bank density between grazed and ungrazed sites in shrub patches and interpatches.

Summary: Seed longevity is crucial for plant germplasm conservation, species reproduction, geographical distribution, crop yield and quality, and food safety. The decrease in seed longevity and vigor during storage directly impacts seed germination and post-germination seedling establishment. Studies have shown that the rapid catabolism of triacylglycerols, fatty acids, and sugars during seed storage is closely linked to seed longevity.

Summary: Quaking aspen is an important component of western U.S. forests, and this study explored the spatial establishment patterns, survival, and growth of aspen seedlings following a large post-fire event in southern Utah. The study found that aspen seedlings were more likely to establish at higher elevations and closer to seed sources, preferred concave microsites, and were tightly associated with burned soil. Aspen seedling persistence was strongly impacted by competition with co-occurring aspen suckers, with survival lower for seedlings closer to nearby suckers and growth reduced in plots with high sucker density.

Summary: This study quantified the responses of different stages of vegetation regeneration to litter at a global scale. The results showed that litter had different effects on seed, seedling, and plant development stages, with negative effects on seedling establishment and positive effects on plant height. Litter had a minor impact on the vegetation community.

Summary: Global increase in unseasonal fires is threatening postfire seedling recruitment due to impacts on seed persistence and seedling establishment. Experimental evidence shows up to 99% reduction in seedling recruitment following unseasonal fires compared to seasonal fires, highlighting the vulnerability of plant regeneration to changing fire seasons.

Summary: Restoration of degraded drylands is crucial to mitigate climate change, with seeding of native species playing a critical role. Research shows that around one-third of seeding projects are successful, while 17% fail. Success of seeding establishment is influenced by factors such as seeding rate, seed size, site aridity, taxonomic identity, and species life form.

Summary: Seed dispersal is crucial for the survival of plant populations, and zoochory is a widely observed method that enables long-distance dispersal through animals. Secondary seed dispersal by far-ranging raptors, such as barn owls, plays a role in colonizing new habitats. In this study, we found that barn owls primarily dispersed seeds through herbivorous Microtus arvalis, indicating the importance of habitats with abundant small mammals. Furthermore, the remains of prey enhanced seedling establishment, suggesting the potential of barn owl-mediated seed dispersal to increase dispersal distance and seed exchange between habitat types.

Summary: This study compared the bacterial communities associated with seeds of seven weed species after burial in soil for two years and demonstrated the relationships between these changes and seed properties as well as attractiveness for a seed predator. The results showed that seed microbiomes remained specific after burial and contained taxa characteristic for both plant endophytes and insect guts. Changes in seed consumption were partially explained by bacterial communities and seed properties.

Summary: Seed size, seed vigor, illumination duration, temperature, water content, and salt concentration all have an impact on the formation and development of maize seedlings. Small seeds have a higher conversion rate than large seeds, prolonged illumination time is beneficial for the formation of strong seedlings, while low temperature, drought stress, and salt stress have negative effects on the utilization of seed storage reserves.

Summary: Accurately assessing community diversity patterns across distributional ranges is important for effective management. Utilizing a range of analytical approaches helps in understanding floristic patterns and improving management. Conservation of floristic diversity in BGW requires protection and management across its range, something which has not previously been adequately addressed.

Summary: Globally, the increasing frequency and severity of large-scale wildfires pose a significant threat to biodiversity. This review proposes novel frameworks to identify plant species and ecosystems that are most in need of management actions as a result of these wildfires. The frameworks consider the impacts of fire events in the context of the whole fire regime and its interactions with other threatening processes. By applying these frameworks, management priorities and responses can be guided to effectively conserve biodiversity and address the challenges posed by changing fire regimes.

Summary: Systematic approaches to conservation assessment are needed to protect plant diversity. However, the completion of threat assessments for endemic plants is weakly related to a country's wealth or the level of threat that species face. The lack of assessment limits national regulation of actions that endanger plant species.
