Interaction of seed dispersal and environmental filtering affects woody encroachment patterns in coastal grassland

Abstract: Encroachment of woody plants into grasslands has occurred worldwide and includes coastal ecosystems. This conversion process is mediated by seed dispersal patterns, environmental filtering, and biotic interactions. As spatiotemporally heterogeneous, harsh environments, barrier islands present a unique set of challenges for dispersal and establishment. Environmental conditions act as filters on dispersed seeds, thereby influencing encroachment and distribution patterns. Seldom have patterns of propagule dispers… Show more

“…75.686 W) is characterized as having high topographic heterogeneity with a long continuous foredune ridge that protects swale communities from overwash events caused during disturbance, as well as general sea spray, sand burial, and other environmental stressors associated with coastal systems (Fig. 1b; Woods et al 2019, Zinnert et al 2019). This is evidenced by no change in the marsh–upland boundary over the last ~30 yr (Zinnert et al 2019).…”

“…Species diversity is restricted as a result of these environmental filters 27,29 . For island landscapes, species diversity is additionally filtered by dispersal 26,27,30 . The vegetation on barrier islands is further limited by the availability of freshwater and precipitation regime; barrier islands have a freshwater lens that is entirely precipitation-fed 21,31,32 .…”
