Groundwater Controls on Wetland Vegetation of a Ridge-and-Swale Chronosequence in a Lake Michigan Embayment Wetlands (IF 1.783) Pub Date : 2020-08-20 Douglas A. Wilcox, Martha L. Carlson Mazur, Todd A. Thompson
A chronosequence of wetland swales between beach ridges in the Manistique/Thompson embayments of Lake Michigan contains plant communities that differ across the strandplain. We characterized vegetation in 33 swales and compared distribution with previously reported groundwater flow systems. Older swales near a groundwater divide created by the peak Nipissing ridge receive local flows and hold sedge/leatherleaf

Wave Attenuation by Spartina alterniflora under Macro-Tidal and Storm Surge Conditions Wetlands (IF 1.783) Pub Date : 2020-08-15 Xiaoxia Zhang, Pengzhi Lin, Zelin Gong, Bing Li, Xinping Chen
Salt marshes are coastal wetlands that provide many ecosystem services. They protect coasts from erosion, storm surge, and small tsunami by dissipating wave energy. Plant flexibility has been reported to reduce drag force on and wave attenuation of marsh plants. In this study, we proposed a new drag coefficient formula to account plant flexibility so that the classical theory based on rigid cylinders

Effect of Water Level and Salinity on Metal Fractionation in Sediments of the Yellow River Delta Wetlands (IF 1.783) Pub Date : 2020-08-13 Xiao Li, Xuehong Wang, Junbao Yu, Jisong Yang, Yang Yu, Di Zhou, Yunzhao Li
In estuarine wetland ecosystems, the heavy metal content and especially the metal fractionation are influenced by water and salinity conditions. We collected sediments from the intertidal zone of the Yellow River Delta, where the water and salinity conditions changed frequently. The incubation experiments at different water and salinity levels were carried out in the laboratory to investigate the migration

Land-Use Changes Associated with Oil Palm Plantations Impact PLFA Microbial Phenotypic Community Structure throughout the Depth of Tropical Peats Wetlands (IF 1.783) Pub Date : 2020-08-11 Selvakumar Dhandapani, Karl Ritz, Stephanie Evers, Hannah Cooper, Amanda Tonks, Sofie Sjögersten
Tropical peatlands are complex and globally-important ecosystems that are increasingly threatened by anthropogenic disturbances, primarily via agricultural development. Microbes in peatlands play important roles in governing overall ecosystem functions and sustenance, with specific population dynamics governing carbon sink or source dynamics. We determined phenotypic microbial community structures
