Title:	Sphagnum fuscum Growth and N Concentration in an Alberta Poor Fen Subjected to Increasing Nitrogen Deposition, 2011-2015
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha-1 yr-1; regional background levels <2 kg N ha-1 yr-1. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a poor fen near Mariana Lake, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). Data collected of the growing season using the crank wire method allowed for the calculation of NPP of the dominant 3 mosses. Tissues were also collected and analyzed for total Nitrogen and Carbon. While we found a modest increase in linear growth and net primary production of S. magellanicum with increasing N addition in three of the 5 years, S. fuscum and S. angustifolium growth were unaffected by N addition. At Mariana Lake Bog, S. fuscum linear growth was unaffected by N addition, although there was evidence for inhibition of NPP S. angustifolium linear growth and NPP were stimulated by fertilization in the first year of fertilization, but by the fourth year fertilization had no effect. Sphagnum capitulum N concentrations were also unaffected by N addition. Given the paucity of data on Sphagnum growth in boreal acidic poor fens, with or without experimental N addition, it is difficult to make generalizations, although it appears that S. fuscum, S. magellanicum, and S. angustifolium responses to increasing N deposition may be species-specific and may differ between bogs and acidic poor fens with much of the N coming from N-fixation.

Description:

Net primary production (NPP) of each of the three dominant Sphagna spp. is the product of linear growth of stems (cm yr-1) and stem mass density (SMD), with SMD defined as the mass of 1-cm lengths of Sphagnum stems beneath the capitula per m2. We measured linear growth using the cranked wire method (Clymo 1970). We set 30 cranked wires in each of the 21 study plots, The poor fen plots had a mixture of Sphagnum fuscum, S. magellanicum, and S. angustifolium; the 30 wires were placed according to species representation within each plot, with wires divided between one, two, or all three species. Each year, from 2011 through 2015, we set cranked wires and remeasured them in late September or early October. To measure SMD, we collected surface monoculture cores (6.5 cm diam.) of each of the three Sphagnum spp. in each plot between July 7th and 10th of each year. From each core, we removed and counted all capitula to determine moss plant density (individual plants m-2). We separated 70 stems of Sphagnum spp., and 40 stems of S. angustifolium, and 40 stems of S. magellanicum to a length of 2 cm and dried the stems at 55 °C for 5 days before weighing. These weights divided by 2 and again by 70 or 40 depending on the species to represent the average mass of a 1-cm stem of an individual Sphagnum plant; this value was multiplied by plant density to yield SMD. From cores collected in early July and early October from 2013 through 2015, we calculated capitulum mass density (CMD) as the dry mass of all capitula from a core, scaled up to a m2 basis. Capitula and stems were dried, homogenized with a Thomas Wiley Mini-Mill, and analyzed for N concentration on a Flash EA 1112 Series CN Soil Analyzer. We calculated the amount of N annually utilized by Sphagnum to satisfy NPP requirements as the product of Sphagnum NPP and the N concentration in the 0-2 cm stem sections. For both summer and fall collections, we calculated the quantity of N stored in capitula (g N m-2) as the product of CMD and N concentration in the capitula.
