20.500.12556/RUL-137575 Limits to reproduction and seed size-number tradeoffs that shape forest dominance and future recovery The relationships that control seed production in trees are fundamental to understanding the evolution of forest species and their capacity to recover from increasing losses to drought, fire, and harvest. A synthesis of fecundity data from 714 species worldwide allowed us to examine hypotheses that are central to quantifying reproduction, a foundation for assessing fitness in forest trees. Four major findings emerged. First, seed production is not constrained by a strict trade-off between seed size and numbers. Instead, seed numbers vary over ten orders of magnitude, with species that invest in large seeds producing more seeds than expected from the 1:1 trade-off. Second, gymnosperms have lower seed production than angiosperms, potentially due to their extra investments in protective woody cones. Third, nutrient-demanding species, indicated by high foliar phosphorus concentrations, have low seed production. Finally, sensitivity of individual species to soil fertility varies widely, limiting the response of community seed production to fertility gradients. In combination, these findings can inform models of forest response that need to incorporate reproductive potential. seed production production control natural disasters reproductive potential pridelava semen nadzor pridelave ujme reprodukcijski potencial true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-22 12:35:29 2022-06-22 12:35:35 2022-09-15 04:15:24 0000-00-00 00:00:00 2022 0 0 12 str. art. 2381 Vol. 13 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-05-02 630*23 2041-1723 10.1038/s41467-022-30037-9 112469251 https://www.nature.com/articles/s41467-022-30037-9 1 dd52b274-f216-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157576 s41467-022-30037-9.pdf s41467-022-30037-9.pdf 1 BD85324D9EEBF7FD4160F184F16AE57F e1a2acdeffd6b1fcae8ecd1955f220297d9e020e9e16d7fbf50e382803da78ae 261e5f54-f217-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157578 Biotehniška fakulteta 0 0 0
