Article Synopsis
- - The study examines the relationship between tree maturation size and reproduction, finding that larger tree species tend to start reproducing at a smaller size than expected, challenging previous assumptions.
- - Researchers analyzed seed production data from 486 tree species across different climates, revealing that maturation size increases with maximum size but not in a straightforward manner.
- - The results indicate that this trend is particularly pronounced in colder climates, highlighting the importance of understanding maturation size to better predict how forests will respond to climate change and disturbances.
Wildfire governance requires addressing driving physical, biological and socio-economic processes, by promoting the development of fire-resistant and resilient landscapes. These landscapes can best be achieved by strategies that integrate fuel management for direct prevention with allied socio-economic activities, through the collaboration of stakeholders with different and sometimes conflicting interests. This work aims to address the need for new approaches supporting the participatory process of collective decision-making, helping stakeholders explore land management strategies for landscape fire resilience.

- Spatial synchrony in seed production of European beech shows stronger alignment during periods of seed scarcity rather than during peak years.
- High interannual variation in seed production, known as masting, leads to synchronous patterns across large distances, with significant effects on resource availability.
- The study found that seed scarcity is widespread across populations up to 1800 km apart, while mast peaks are synchronized over distances up to 1000 km, indicating that food shortages can have amplified consequences on ecosystems and climate dynamics.
Many perennial plants show mast seeding, characterized by synchronous and highly variable reproduction across years. We propose a general model of masting, integrating proximate factors (environmental variation, weather cues, and resource budgets) with ultimate drivers (predator satiation and pollination efficiency). This general model shows how the relationships between masting and weather shape the diverse responses of species to climate warming, ranging from no change to lower interannual variation or reproductive failure.
