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.
Article Synopsis
- Masting is when trees produce a lot of seeds at different times, which helps them survive by confusing animals that eat seeds.
- However, this can be bad for the animals that help trees spread their seeds because they rely on a steady food supply.
- Researchers found that some trees avoid masting to keep their disperser animals happy, especially in different climates and depending on how much nutrients they need to grow.
Assessing long-term changes in the biomass of old-growth forests with consideration of climate effects is essential for understanding forest ecosystem functions under a changing climate. Long-term biomass changes are the result of accumulated short-term changes, which can be affected by endogenous processes such as gap filling in small-scale canopy openings. Here, we used 26 years (1993-2019) of repeated tree census data in an old-growth, cool-temperate, mixed deciduous forest that contains three topographic units (riparian, denuded slope, and terrace) in northern Japan to document decadal changes in aboveground biomass (AGB) and their processes in relation to endogenous processes and climatic factors.
