Interactive effects of light, water, soil type and competition on the endangered Minuartia smejkalii vary over time

Understanding drivers of species performance is crucial for their effective conservation. Despite a range studies on the effects single biotic and abiotic factors plant performance, very little known about interactions among multiple over time. We studied competition in an endemic Czech Republic, serpentinophyte Minuartia smejkalii, four years. In full factorial experiment, we evaluated M. smejkalii alone, presence competitor, Festuca ovina, under different conditions, including types soil, light exposure water regime, observed its changes The results indicate complex these factors. Competition had negative (1.2 times larger plants 1.8 more flowers absence competitor), but stronger than alone. F. ovina also varied depending whether shaded or not soil conditions. Biotic contrasting number flowers, suggesting that investment growth reproduction are context dependent. size grown areas was 2.7 those sun, whereas sun produced 1.7 Type did affect area, 1.5 non-serpentine soils. Our suggest complex, interact with vary highlight importance long-term to identify competitive studying how might endangered certain conditions (i.e. water, shading), provides essential information implementation efficient conservation strategies.
