Germination and seedling frost tolerance differ between the native and invasive range in common ragweed

Abstract: Germination characteristics and frost tolerance of seedlings are crucial parameters for establishment and invasion success of plants. The characterization of differences between populations in native and invasive ranges may improve our understanding of range expansion and adaptation. Here, we investigated germination characteristics of Ambrosia artemisiifolia L., a successful invader in Europe, under a temperature gradient between 5 and 25 °C. Besides rate and speed of germination we determined optimal, minima… Show more

“…In contrast, for other common ragweed life history traits, e.g. germination traits, no correlations with environmental factors have been found, despite a high level of variation between populations for these traits (Leiblein-Wild et al 2013). Most of the differences between populations observed in this study were correlated with environmental parameters and/or the geographical origin.…”

“…This factor was identified as the main splitter between the two stages of the invasion process (following the terminology of Richardson et al 2000, Blackburn et al 2011. This is in accordance with experimentally demonstrated effect of low temperature in slowing down the rate of seed germination (Leiblein-Wild et al 2014) and development of seedlings (Skálová et al 2015) and leaves (Deen et al 1998). The negative effect of low temperature may be partly compensated by an increased nutrient availability (Skálová et al 2015), which may explain the occurrence at disturbed sites (where nutrient availability is usually high) and facilitate further spread into arable fields.…”

“…Such change can contribute to their invasion success, for example, by altering phenotypic traits (Bossdorf et al 2005) that enhances tolerance to biotic or abiotic conditions (Maron et al 2004; Abhilasha and Joshi 2009; Leiblein-Wild et al 2014), or increasing early life cycle traits like germination or seedling growth (Blair and Wolfe 2004). Early life cycle trait performances are of great importance for the spread and establishment of introduced populations in a new range.…”
