Consequences of propagule dispersal and river fragmentation for riparian plant community diversity and turnover

Abstract: Consequences of propagule dispersal and river fragmentation for riparian plant community diversity and turnover. Abstract. The spatial distribution and temporal availability of propagules fundamentally constrain plant community development. This study experimentally tested several hypotheses about the relative roles of wind and water dispersal in colonization and development of riparian communities along rivers. Through controlling the source of propagules (dispersed by wind, water, or both) reaching newly cr… Show more

“…More specific predictions at the level of traits (e.g., trade-offs) or combination of attributes could be tested experimentally (e.g., [23,53,113,[134][135][136]). A more mechanistic and experimental approach could lead to more predictive species distribution and associated community structure against our changing climate and management practices [34,137].…”

“…Dispersal of propagules and establishment of new plant populations is also highly dependent upon these stream flow events, which ironically not only destroy existing populations but also opens up suitable habitat for colonization (Naiman et al 1997, Wintle andKirkpatrick 2007). Given the stochastic success of sexual reproduction in such an environment, dispersal and gene flow of these plants can be limited to movement of vegetative propagules (rhizomes) and occasional seeds downstream within watersheds, as opposed to other non-riparian species in which both seed and pollen may be dispersed more broadly across the landscape (Johansson et al 1996, Merritt et al 2010. However, water dispersal also potentially allows for long-distance gene flow between geographically connected, yet widespread populations (Johansson and Nilsson 1993).…”

“…Propagule pressure has been shown to affect the distribution and abundance of many invasive plants [58,59] and, like many other invasive plants, recruitment limitation tends to slow the range expansion of Japanese honeysuckle [60,61]. These results support the concept that invasions are best mitigated during the early stages of recruitment and establishment [62,63] or via control of outlier populations [64].…”
