Floral spectral reflectance data for: Floral color properties of serpentine seep assemblages depend on community size and species richness

Functional traits, particularly those that impact fitness, can shape the ecological and evolutionary relationships among coexisting species of the same trophic level. Thus, examining these traits and properties of their distributions (underdispersion, overdispersion) within communities can provide insights into key ecological interactions (e.g., competition, facilitation) involved in community assembly. For instance, the distribution of floral colors in a community may reflect pollinator-mediated interactions between sympatric plant species, and the phylogenetic distribution of color can inform how evolutionary contingencies can continue to shape extant community assemblages. Additionally, the abundance and species richness of the local habitat may influence the type or strength of ecological interactions among co-occurring species. To evaluate the impact of community size and species richness on mechanisms shaping the distribution of ecologically relevant traits, we examined how floral...功能性状（functional traits），尤其是那些影响适合度（fitness）的性状，可塑造同一营养级（trophic level）共存物种间的生态与进化关系。因此，对群落内这些性状及其分布特征（欠离散（underdispersion）、过离散（overdispersion））的研究，能够为揭示群落构建（community assembly）过程中涉及的关键生态相互作用（如竞争、促进作用）提供见解。例如，群落内花色的分布格局可反映同域分布（sympatric）植物物种间由传粉者介导的（pollinator-mediated）相互作用，而花色的系统发育分布（phylogenetic distribution）则可阐明进化偶然性（evolutionary contingencies）如何持续塑造现存群落组合。此外，本地生境的物种丰度与物种丰富度，可能会影响共存物种间生态相互作用的类型与强度。为评估群落规模与物种丰富度对塑造生态相关性状分布的机制的影响，本研究考察了花色……
