Premise: Tree structure and function are constrained by and acclimate to climatic conditions. Drought limits plant growth and carbon acquisition and can result in "legacy" effects that last beyond the period of water stress. Leaf and twig-level legacy effects of past water abundance, such as that experienced by trees that established under wetter conditions are unknown.

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
  • Lack of data on tree seed production across different climates makes it hard to understand how seed availability affects forest regeneration and biodiversity.
  • A global analysis shows that seed abundance increases significantly (by 250 times) from cold-dry to warm-wet climates, mainly due to a hundredfold increase in seeds produced by the same size tree.
  • This dramatic rise in seed supply could be influenced by either evolutionary adaptations to intense species interactions or by the warm, moist climate's direct impact on tree fecundity, which may also affect food webs and species interactions, especially in wet tropical regions.

This paper introduces two families of orthogonal polynomials on the interval (-1,1), with weight function [Formula: see text]. The first family satisfies the boundary condition [Formula: see text], and the second one satisfies the boundary conditions [Formula: see text]. These boundary conditions arise naturally from PDEs defined on a disk with Dirichlet boundary conditions and the requirement of regularity in Cartesian coordinates.
