Библиографическое описание: Trade-off strategies between growth and defense of spring ephemeral plants in early spring : научное издание / L. Pan, T. Wang, Vladimir L. Gavrikov [и др.]. - Текст : непосредственный // Frontiers in Plant Science. - 2025. - Т. 16, № . - ISSN 1664-462X, DOI 10.3389/fpls.2025.1503169.
Аннотация: <jats:sec><jats:title>Introduction</jats:title><jats:p>Spring ephemeral plants represent a unique ecological category of herbaceous plants, characterized by early blooming and vivid flowers with significant ornamental value. Understanding the adaptive strategies of spring ephemerals is crucial for the introduction and cultivation of early spring plants, as well as for optimizing light energy utilization and nutrient cycling within ecosystems.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>We evaluated 26 functional traits across four spring ephemerals and four spring non-ephemeral plants along an elevation gradient. By establishing a plant functional trait network, we examined the adaptation strategies of early spring plants at different elevations and compared the differences in adaptation strategies between two types of plants.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Spring ephemerals exhibited higher concentrations of carbon and nitrogen, lower concentrations of carbohydrates, higher edge density and modularity in trait networks, and stronger linkages between defense traits. Plants at higher elevations demonstrated higher leaf dry matter content and leaf total flavonoid concentration, and lower nitrogen concentration, influenced by temperature, precipitation, and soil nutrients.</jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p>These results demonstrated that spring ephemerals have a strong nutrient uptake capacity, and adopt resource competition strategies to rapidly accumulate nutrients and reproduce. The plants at higher elevations adopt more conservative strategies, with trait networks showing increased modularity, edge density, and closer correlations among traits to enhance resource utilization. This study provides new insights into the adaptive strategies of spring ephemerals by demonstrating how plants allocate resources for growth and defense through the regulation of trait variation and correlations among traits.</jats:p></jats:sec>
