Changes in forest diversity over a chronosequence of fluvial islands

Abstract: The high environmental heterogeneity of large fluvial systems is reflected by the co-existence of contrasting plant communities and landforms. The main objective of this study was to assess the forest diversity changes in islands of the Middle Paraná River (Argentina) in order to discuss an integrative question: how synchronized are the major changes in the features of islands and forests? Persistence age, elevation and flood regime of 11 main channel islands were determined. Variables related to the vascular … Show more

“…Along the four stages, the importance of the physical and abiotic factors that control the succession decreases, whereas that of biotic factors increases, and, as indicated above, the biogeomorphic stage starts with the germination of T. integrifolia and S. humboldtiana (Brumnich et al, 2019). These pioneer tree species act as traps for sediments, a fact that in turn allows an increase in the elevation of sand bars, and next allows the germination and recruitment of other plant species (Brumnich et al, 2019). Consequently, the forest types and relative abundance of plant species on islands are defined by topographic, edaphic and age factors (Casco & Neiff, 2013; Daly & Mitchell, 2000; Daly & Prance, 1989).…”

“…As in other fluvial systems, these Paraná islands present four succession stages (i.e. the geomorphic, pioneer, biogeomorphic and ecological stages) (Brumnich et al, 2019; Corenblit et al, 2007). Along the four stages, the importance of the physical and abiotic factors that control the succession decreases, whereas that of biotic factors increases, and, as indicated above, the biogeomorphic stage starts with the germination of T. integrifolia and S. humboldtiana (Brumnich et al, 2019).…”

“…Otras especies relevantes en igual sentido son el sauce y el aliso, ya que en meses colonizan las nuevas áreas sedimentadas en los cauces, sea en bancos centrales como laterales, contribuyendo a su consolidación (Brumnich et al, 2019;Foto 2.6).…”
