“…Nutrient availability in sediments is reflected by greater aboveground biomass and nitrogen storage. In South Carolina, Noe et al (2014) indicated that the increased availability of nitrogen enables S. alterniflorus to out compete black needlerush but allows an increase in biomass and nitrogen storage in J. roemerianus. Ledford et al (2020) found that a threefold nutrient enhancement had no effect on black needlerush.…”

Juncus roemerianus Scheele, black needlerush, is a rhizomatous salt marsh species that often forms dense monotypic stands in the mid-and high marshes along the mid-to SE Atlantic coastline and southward to the upper Texas coast in the United States. A dense rhizome complex allows this taxon to reproduce asexually and to exclude potential competitors. Juncus roemerianus has numerous ecosystem functions, including carbon sequestration, control of erosion, protection from storm surges, and as a nursery for numerous marine organisms. This species tolerates a range of salinity generally less than 5.0 ppt to as high as 35 ppt in a few marshes. Juncus roemerianus is noted for its high levels of productivity in below-and aboveground biomass values. Black needlerush is highly sensitive to oil pollution, much more so than its closest associate in the salt marsh community Sporoblus alterniflorus. Juncus roemerianus plays an important role in revegetating disturbed marshes and has a potential role for preventing the re-invasion of Phragmites australis in newly created marshes.

“…Distinct changes would occur during the paludification and disappearance processes because of continuous interruption triggered by human activities. Numerous studies have been conducted with different emphases, such as sustainable uses of lake resources (Zalewski, 2000;Cruickshank and Grover, 2012;Pavri et al, 2013), water or sediment pollution in lakes by heavy metals and persistent organic pollutants (Smol, 2008;Jernström et al, 2010;Schmid et al, 2010;Bai et al, 2011), lake eutrophication induced by the mass input of nutrients (e.g., nitrogen and phosphorus) (Paerl et al, 2011;Yuan et al, 2011;Schindler, 2012;Søndergaard et al, 2013), and lake siltation and marsh development with respect to natural and/or anthropogenic activities (Xue et al, 2008;Brauneck et al, 2012;Kirwan and Murray, 2012;Noe et al, 2013).…”

Radionuclide dating techniques characterized by 137 Cs and 210 Pb ex have recently been applied in the study of lake sediments around the world. In this study, a chronological series of sediment cores was established based on 137 Cs and 210 Pb ex analyses along with the evaluation of sediment properties, such as particle size distribution, total organic carbon (TOC), carbonate content, and acid-insoluble residue, to study sediment accumulation rates, sediment sources, and responses to human activities in the Jiuzhaigou National Nature Reserve in southwestern China. In terms of the particle size distribution of sediments, silt content was the highest, and clay and sand contents were relatively low. The sediments displayed high TOC contents because of the significant amounts of vegetation grown in the lakes. The carbonate content was also high due to the overall geological background of carbonates in Jiuzhaigou. Carbonate content tended to decline from top to bottom in the sediment cores, whereas the acid-insoluble residue tended to increase. These results suggested that the depth variation of the environmental parameters of the sediments in two lakes in Jiuzhaigou would correspond to each other. The results indicated that the sediment rate of Jiuzhaigou was generally high with strong siltation, indicating that serious soil loss was induced by intensive human activities in the basin over the past decades. The increases in the mass accumulation rate, contents of acid-insoluble residue, and mean particle size during the periods of 1840-1900s, late 1930s-early 1950s, 1966-1978, and 2003-2006 revealed the occurrence of severe soil and water loss as a result of extensive agricultural expansion, large-scale deforestation, and road construction in Jiuzhaigou. The deposition rate and the properties of lacustrine sediments could reflect the significant impact of human activities on lake sedimentation during Jiuzhaigou′s history.
