Species Distributions on Successional and Flooding Gradients in Connecticut River Floodplain Forests
Abstract - Floodplain forests provide valuable ecosystem services, yet human activity has degraded many of these riverine systems. Previous investigations of floodplain forest composition have frequently focused on flooding without incorporating successional dynamics; however, their restoration requires understanding both. We investigated floodplain forest composition along both flooding and succession gradients. River meandering builds new floodplain land with a variable microtopography and diverse levels of flood exposure. We compared vegetation to floodplain land ages on chronological sequences. Our results suggest that diverse species assemblages in floodplains result at least in part from geomorphic change. Ensuring that flood pulses continue to erode riverbanks and deposit sediments on sandbars and in floodplains is essential to the restoration and conservation of diverse forest assemblages in these ecosystems.
期刊介绍:
The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion.
The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
