seed-ecology
Seed ecology is the study of how seeds interact with their environment across the stages of dispersal, dormancy, germination, and seedling establishment. It is fundamental to plant science because these processes determine where and when plant populations recruit, shaping species distributions, community composition, and ecosystem resilience. Understanding seed ecology informs conservation efforts, habitat restoration, and agricultural strategies for managing plant reproduction under changing environmental conditions.

A study of 33 grassland herbs found that the link between a plant's leaf production and its seed output is strongly shaped by plant type — annuals and wildflowers show tight leaf-to-seed coordination, while perennial grasses do not — and that year-to-year weather swings can switch these relationships on or off entirely.
Species identity explained at least 95% of variation in leaf and seed traits, meaning the type of plant matters far more than local environmental noise.
Annual species and forbs showed strong positive leaf-seed correlations (e.g., leaf number vs. seed number), while perennial grasses showed decoupled relationships with no consistent link between leaf and seed traits.
Seeding intensity increased with leafing intensity in 2017 but not in 2016, demonstrating that interannual climate variability can switch leaf-to-seed coordination on or off across the same community of plants.
