Nitrogen-rich groundwater intrusion affects productivity, but not herbivory, of the tropical seagrass Thalassia testudinum

Individual and population indicators of Zostera japonica respond quickly to experimental addition of sediment-nutrient and organic matter

“…In our study, sediment nutrient increased leaf length and belowground biomass of seagrasses, which indicated that nutrients are used for seagrasses growth (Short, 1983;Peterson et al, 2012). Previous studies also showed sediment nutrient fertilization increased leaves biomass (e.g.…”

“…Nutrient availability is reflected within seagrasses via increased growth (Peterson et al, 2012). In our study, sediment nutrient increased leaf length and belowground biomass of seagrasses, which indicated that nutrients are used for seagrasses growth (Short, 1983;Peterson et al, 2012).…”

“…Plants exposed to high nutrient loads can show physiological change, such as increases in tissue nutrient content (Invers et al, 2004;Peterson et al, 2012;Pérez et al, 2007;Udy and Dennison, 1997a). In our study, N content of seagrass roots and rhizomes was lower than 1.8% of the dry weight (Table 1; Fig.…”

“…Previous studies also showed sediment nutrient fertilization increased leaves biomass (e.g. Hemminga and Duarte, 2000;La Nafie et al, 2013;Lee and Dunton, 1999;Peralta et al, 2003;Peterson et al, 2012). Nutrient availability may be incorporated into the carbohydrate reserves of seagrasses (e.g.…”

Ecosystem structure in disturbed and restored subtropical seagrass meadows

“…In south Florida and the Caribbean, the dominant seagrass species include Thalassia testudinum, Syringodium filiforme, and Halodule wrightii, which occur in both monospecific and mixed beds (McMillan & Phillips 1979;Thorhaug 1981). Nutrient content varies among and within these species over relatively small spatial scales in response to terrestrial, oceanic, groundwater, or point source inputs (Fourqurean et al 1992a;Caccia & Boyer 2005;Campbell & Fourqurean 2009;Peterson et al 2012). Thus local seagrass landscapes can exhibit substantial variation in community composition and stoichiometry, to which herbivores respond.…”
