Long-Term Effects of Adding Nutrients to an Oligotrophic Coastal Environment

Armitage, Anna R., Frankovich, Thomas A., Fourqurean, James W.·2011·Ecosystems

Abstract

Management of ecological disturbances requires an understanding of the time scale and dynamics of community responses to disturbance events. To characterize long-term seagrass bed responses to nutrient enrichment, we established six study sites in Florida Bay, USA. In 24 plots (0.25 m²) at each site, we regularly added nitrogen (N) and phosphorus (P) in a factorial design for 7 years. Five of the six sites exhibited strong P limitation. Over the first 2 years, P enrichment increased Thalassia testudinum cover in the three most P-limited sites. After 3 years, Halodule wrightii began to colonize many of the P-addition plots, but the degree of colonization was variable among sites, possibly due to differences in the supply of viable propagules. Thalassia increased its allocation to aboveground tissue in response to P enrichment; Halodule increased in total biomass but did not appear to change its aboveground: belowground tissue allocation. Nutrient enrichment did not cause macroalgal or epiphytic overgrowth of the seagrass. Nitrogen retention in the study plots was variable but relatively low, whereas phosphorus retention was very high, often exceeding 100% of the P added as fertilizer over the course of our experiments. Phosphorus retentions exceeding 100% may have been facilitated by increases in Thalassia aboveground biomass, which promoted the settlement of suspended particulate matter containing phosphorus. Our study demonstrated that low-intensity press disturbance events…

  • Previous studies have effectively used these enrichment methods to increase nutrient availability to the above- and below-ground biomass of benthic macrophytes, as well as the epiphyte community in South Florida.

    “Previous studies have effectively used these enrichment methods to increase nutrient availability to the above- and below-ground biomass of benthic macrophytes, as well as the epiphyte community in South Florida (Armitage & Fourqurean 2009; Armitage, Frankovich & Fourqurean 2011; Ferdie & Fourqurean 2004; Frankovich et al. 2009).”

  • Our findings are consistent with prior studies suggesting that epiphyte responses to nutrient enrichment can be variable and site-specific within this region.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
