Rainfall variability counteracts N addition by promoting invasiveLonicera maackiiand extending phenology in prairie

AbstractAlthough encroaching woody plants have reduced the global extent of grasslands, continuing increases in soil nitrogen availability could slow this trend by favoring resident herbaceous species. At the same time, projected increases in rainfall variability could promote woody encroachment by aligning spatiotemporal patterns of soil moisture availability with the needs of woody species. We evaluated the responses of two deciduous woody species to these simulated environmental changes by planting seedlings ofQuercus palustrisandLonicera maackiiinto tallgrass prairie communities grown under a factorial combination of increased rainfall variability and nitrogen addition.Lonicera maackiigrowth was reduced 20% by nitrogen addition, and increased rainfall variability led to 33% larger seedlings, despite greater competition for light and soil resources. In contrast,Q. palustrisgrowth showed little response to either treatment. Increased rainfall variability allowed both species to retain their leaves for an additional 6.5 d in autumn, potentially in response to wetter end‐of‐season shallow soils. Our findings suggest increases in rainfall variability will counteract the inhibitory effect of nitrogen deposition on growth ofL. maackii, extend autumn phenology, and promote the encroachment of some woody species into grasslands.
