Spatiotemporal variation in deer browse and tolerance in a woodland herHR Prendeville, JC Steven, LF Galloway - Ecology, 2014
 ... To investigate broad-scale patterns of deer herbivory, we examined the frequency and reproductive consequences of deer browse over three years in 17 populations of Campanulastrum americanum spanning the latitudinal extent of its range. Even though deer are overabundant throughout the range of C. americanum, we found spatiotemporal variation in deer browse frequency (0-0.96, mean 0.46) and its effects on plant reproductive success. The four southernmost populations experienced high levels of herbivory ... Across many populations and years, average fitnesses of browsed and uneaten plants were similar, suggesting that plants are tolerant to browse. However, since large plants have greater reproductive success and are more likely to be browsed, tolerance may be influenced by plant size...
