Abstract

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.

康涅狄格河漫滩森林演替和洪水梯度的物种分布

摘要-洪泛平原森林提供了宝贵的生态系统服务，但人类活动已经使许多河流系统退化。先前对泛滥平原森林组成的调查经常集中在洪水上，而没有纳入演替动力学；然而，它们的修复需要理解两者。我们调查了沿洪水和演替梯度的泛滥平原森林组成。河流蜿蜒形成了具有可变微观地形和不同洪水暴露水平的新洪泛平原。我们根据时间序列比较了植被和泛滥平原的年代。我们的研究结果表明，洪泛平原中不同的物种组合至少部分是地貌变化的结果。确保洪水脉冲继续侵蚀河岸，并在沙洲和泛滥平原沉积沉积物，对于恢复和保护这些生态系统中的各种森林群落至关重要。

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.
