Reproductive traits
Life history strategies related to reproduction are similarly connected with trade-offs in allocation patterns. For example, larger seeds and those that require longer germination times tend to have increased pathogen susceptibility (Pringleet al. 2007; Beckman & Muller-Landau 2011; Beckstead et al. 2014; Domínguez‐Begines et al. 2020). However, seed traits related to dormancy (e.g. physical barriers, chemical defense, association with beneficial microbes, and germination time) are associated with resistance to pathogen infection (Dalling et al.2011). These seed defense syndromes provide a framework to study if seed traits of invasive plants influence the probability of pathogen accumulation. Seed and plant traits such as seed mass, plant height, and dispersal mode also influence seed dispersal distance (Thomson et al.2011; Tamme et al. 2014), which is an important determinant of density dependent pathogen effects and negative plant-soil feedbacks (Augspurger & Kelly 1984). Foraging arthropods, including pollinators and herbivores, can transmit pathogens among plants (Durrer & Schmid-Hempel 1994). Plants with more attractive flowers (e.g, higher nectar production) may thus be particularly susceptible to pathogen attack (Rocheet al. 1995; Shykoff & Bucheli 1995; Shykoff et al. 1996; Ferrari et al. 2007).
