Idiosyncratic shifts in life-history traits at species’ geographic range edges

Anne Duputié, Mathilde Latron, Jean-Francois Arnaud, Eric Schmitt & Anne Duputié
Anthropogenic changes drive shifts in species’ geographic distributions and increase the occurrence of leading or trailing-edge marginal populations. Theoretical predictions and empirical observations indicate substantial changes in life-history traits in marginal populations, often involving dispersal and reproductive abilities. Using a common garden experiment, we studied the variation of life-history traits of populations sampled on spatial gradients extending from range-core to range-edge habitats for three expanding (miner’s lettuce Claytonia perfoliata, Danish scurvygrass Cochlearia danica, and rock...
