Research Interests

My interests lie in the relationships between soil and the environment, particularly the regulation of fluxes of gases, nutrients and elements between the soil and the atmosphere, the biosphere and the hydrosphere and the effect of human activities and climate change.

For the past decade, most of my attention has focused on peatlands and wetlands and the controls on the cycling of carbon in these systems. Northern peatlands contain one third of the global soil carbon pool, store carbon dioxide (CO2) in accumulating peat, emit methane (CH4) to the atmosphere and are major sources of dissolved organic carbon (DOC). My work, in landscapes ranging from the Northwest Territories to Nova Scotia, has attempted to measure the magnitude of these fluxes, to establish the important controls, to develop models and to examine the effect of changes, such as directly anthropogenic (for example, through the drainage or flooding of peatlands) or indirectly (for example, through climatic change and atmospheric nitrogen deposition) on carbon cycling. Thus, my work integrates aspects of atmospheric chemistry, plant ecology, hydrology, microbiology and soil science in a search to understand biogeochemical patterns in the landscape.

Research opportunities

Dynamics and chemistry of dissolved organic carbon (DOC) and nitrogen in peatlands: Although we know the concentration of DOC in peat porewater and can estimate export of DOC from a peatland, we have little understanding on the rates of DOC production, consumption and transport within peatlands, and its role in N cycling. This study will be based at Mer Bleue and involve both field-work and laboratory experiments to determine where the DOC comes from and how it is processed by the column, and linking with peatland C models.

Nitrogen fixation in peatlands: Peatlands store substantial amounts of nitrogen (N) along with carbon (C); the main input of N to peatlands is from the atmosphere or through N2 fixation, but little is know about the latter process. This project will examine the rates of N2 fixation at the range of sites (hummock-hollow-beaver pond-fertilized plots) at Mer Bleue using the acetylene reduction method, and establish the major controls on these N2 fixation rates.

Root dynamics in peatlands
Below-ground activities in ecosystems are the ‘Final Frontier’ (Science [2004] 304: 1614-1637) and this is probably particularly the case in wetlands. We have established gradients of species composition and production at Mer Bleue in response to water table position - above:belowground quotients range from 0.3 to 0.6. Mini-rhizotron tubes inserted to the rooting depth along a hummock-hollow sequence and in the fertilizer plots will measure root demographics at monthly intervals.

Response of a bog community to N and P additions
Bogs are oligotrophic and ombrotrophic systems, with low nutrient availability and are being exposed to increased nutrient inputs, especially increases in atmospheric N deposition. To determine the long-term effect of increased nutrient additions, in 2000 I established a study at Mer Bleue with triplicated plots 3 x 3 m with treatments representing 0, 1.6, 3.2, and 6.4 g N m-2 y-1, or 5, 10, and 20 times the growing-season N deposition and about 2, 4 and 8 times the annual deposition. Opportunities are available to establish the response of plant species and their C exchange, of nutrient uptake and release and of ecosystem CO2, CH4 and N2O exchange.

Research Themes

Peatland biogeochemistry

Mer Bleue is the eastern peatland within the Canadian Carbon Program (http://www.fluxnet-canada.ca ). At this site (Figures 1 to 5) an eddy covariance tower operated by Elyn Humphreys (Carleton University) and Peter Lafleur (Trent University) has measured CO2 exchange since 1998 providing an assessment of the seasonal and interannual variability and the influence of changes in climate and water table. Combination of CO2 exchange, CH4 flux and DOC export over 6 years provides an estimate of the interannual variability of the overall C flux in this system (Rouklet et al. 2007).

My work at Mer Bleue, in collaboration with Jill Bubier (Mount Holyoke College, MA), has involved studies of rates of decomposition of litter and peat (e.g. Scanlon and Moore 2000; Moore et al. 2007), of biomass and plant production and distribution (e.g. Moore et al. 2002; Bubier et al. 2006), of CO2 exchange from chambers covering the range of vegetation types from bog to beaver pond (e.g. Bubier et al. 2003) and controls on ecosystem respiration (Lafleur et al. 2006) and the onset of spring photosynthesis in this system (Moore et al. 2006). We have measured CH4 flux at 12 sites over 5 years to define the environmental controls (Moore et al. submitted) and Kerry Dinsmore and Mike Billett (Centre for Ecology and Hydrology, Penicuik, Scotland) have examined fluxes from the beaver ponds).

To evaluate the effect of nutrients on the bog, we are conducting a long-term (12-year +) fertilization with N, P and K, and determining plant and CO2 flux response: vegetation (Fig. 6) and CO2 exchange changes have been observed among the 6 experimental treatments (Bubier et al. 2007; Juutinen et al. in press). Christian Blodau (University of Guelph) conducted a 15N tracing experiment at the fertilized plots (Xing et al. in press). Although there is increased N concentration in shrub leaves in the fertilized plots, there is a weak response in leaf photosynthesis suggesting that, in these bog shrubs, N uptake is stored rather than being in a form enhancing photosynthesis (Bubier et al. submitted). Work by PhD student Meng Wang suggests that the vegetation at Mer Bleue is mainly N and P-limited and nutrient limitation in the fertilized plots will be determined in 2011.

Focus is now being placed on linking the C and N cycles, involving measurements of microbial activities (Basiliko et al. 2005), of [N] and 15N in vegetation and peat, incubation studies of rates of NH4+, NO3- and dissolved organic nitrogen production and N fixation. MSc student Amanda Alfonso is establishing whether peatland plants can take up organic N, using 13C and 15N labeled glycine.

Although we know a lot about above-ground plant activities, understanding the role of roots in peatlands is weak. Post-doctoral Fellow Meaghan Murphy has determined below-ground activities at the Mer Bleue peatland (Murphy et al. 2009 and Murphy and Moore in press) and has installed mini-rhizons to determine root demography and phenology in the peatland and in the fertilization plots.

As part of a broad study of the C dynamics of peatlands in the James Bay region, in collaboration with Nigel Roulet, Jukka Turunen (Geologic Survey of Finland, Kuopio), Michelle Garneau (UQAM) and Pierre Richard (Université de Montréal), M.Sc. student Luc Pelletier measured CO2 and CH4 fluxes from peatlands and small pools Pelletier et al. 2007) and Ph.D. student Nicola McEnroe (McEnroe et al. 2009) examined the biogeochemistry of pools in these northern peatlands.

Sampling of ombrotrophic bogs from northwestern Ontario to the Maritimes and their dating with 210Pb has provided an assessment of recent rates of accumulation of C, N and S in peat and the influence of climate and atmospheric N and S deposition (Turunen et al. 2004; Moore et al. 2005). To estimate industrial contaminant deposition, the cores have been analyzed for poly-aromatic hydrocarbons (Christian Blodau and Anna Dryer, University of Bayreuth). The cores have been analyzed for Hg by Brian Branfireun (University of Western Ontario), to provide a record of the spatial and temporal variation in atmospheric Hg deposition in eastern Canada.

Methane and graves

As part of a SSHRC-sponsored project on the detection of clandestine graves led by Margaret Kalacska, Mike Dalva and I have been examining patterns of CH4 emission from soils in an animal graveyard of Parc Safari Africain, near Hemmingford, QC. Graves emit large amounts of CH4 to the atmosphere, sampling of the [CH4] in the atmosphere just above the soil surface at dawn after a still night reveals the patterns of graves and the soils around graces show high rates of both CH4 production and consumption.

Methane and nitrous oxide fluxes from Canadian forests

Dissolved organic carbon (DOC) in forests

We examined the role of DOC in C cycling within upland forests, supported by BIOCAP and NSERC. Measurements were made of field DOC fluxes, and laboratory experiments performed on DOC production, biodegradability, sorption and chemistry and modelling (Ph.D. students Julie Turgeon and Dolly Kothawala). Sources, sinks and fluxes of DOC were made at the Turkey Point ON (Peichl et al. 2007) and Campbell River BC Fluxnet sites. Sorption studies revealed the importance of mineral soil chemistry on DOC and N sorption (Kothawala et al. 2008, 2009) and DOC production studies revealed the importance of DOM chemistry and temperature (Moore et al. 2008).

Litter decomposition and ecological stoichiometry

Rates of litter decomposition in litter-bags over 5 to 6 years have been determined at several peatland sites across eastern Canada (e.g. Schefferville QC, Sept-Iles QC, Mont St Hilaire QC, Mer Bleue ON and Experimental Lakes Area, ON). Controls of litter chemistry and site have been established (Moore et al. 2007) and a synthesis from all sites is being prepared.

Similar, 5-year litter-bag studies have been established in restiad peatlands near Hamilton, North Island New Zealand (in collaboration with Bev Clarkson, Landcare Research, Figure 7) and in pocosin peatlands, Coastal Plain, North Carolina (in collaboration with Curt Richardson, Duke University, Figure 8). Rates of litter decomposition, and their thermal, hydrologic and litter quality controls will be established for these ombrogenous systems, and inclusion of Typha litter from Mer Bleue allows a comparison with northern peatlands.

Work on forest litter decomposition includes the CIDET (Canadian Intersite Decomposition Experiment) in which 12 litter types were decomposed in litter-bags at 20 upland forest and 3 wetland sites across Canada, over a 12 year period. Patterns of decomposition rates and their climatic and tissue controls over 6 years have been published (Moore et al. 1999; Trofymow et al. 2002).  Comparison of decomposition rates in three pairs of upland and adjacent peatlands in central Canada failed to show any strong differences in C, N and P changes over the first 6 years, though there was greater differentiation after 12 years (Moore et al. 2005, 2008). Analysis of N and P dynamics of the litters across all sites shows a general pattern of retention or loss controlled by litter C:N and C:P ratios as well as the site characteristics, with an overall ‘Redfield Ratio’ of 427C:17N:1P when only 20% of the original litter C remained (Moore et al. 2006, in press).

Restored peatlands

Near Rivière du Loup (QC) and Shippagan (NB), we have examined the effect of drainage and harvesting of peat moss on the C cycle and whether vegetation restoration practices can bring back the peat to C cycling function similar to that before the peat was disturbed (Figures 9 to 11). Post-doctoral Fellow Stephan Glatzel (now University of Rostock, Germany) showed the variation in CO2 and CH4 production potentials of peats at these sites (Glatzel et al. 2004), and the patterns of porewater DOC and influence on CO2 emission rates (Glatzel et al. 2003). M.Sc. student Michele Marinier determined the influence of cotton-grass on CO2 and CH4 fluxes (Marinier et al. 2004). We are currently preparing a manuscript examining changes in gas fluxes from natural peatlands through drainage and harvesting to restoration. Ph.D. student Nate Basiliko (now University of Toronto) determined the potential of peat natural, harvested and restored to exchange CH4 and CO2 and the controls on these potentials (Basiliko et al. 2007). M.Sc. student Julian Cleary (now University of Toronto) performed a C life-cycle analysis of the Sphagnum-peat industry in Canada (Cleary et al. 2005).

Soil carbon and land-use change

I have become involved in broader issues of carbon sequestration in soils, particularly in response to land-use change. In 2001 in Sardinilla, Panama, a large old pasture was converted to a native tree plantation by Catherine Potvin (Biology, McGill) in collaboration with the Smithsonian Tropical Research Institute (Figure 12). M.Sc. student Muriel Abraham determined the pattern of soil characteristics using geo-statistical techniques for the surface layers (0-10 cm) as well as the soil profile. Changes in C cycling and the role of biodiversity have been noted (e.g. Potvin et al. 2004, in press). The site soils will be resampled in June 2011 to provide a well-controlled study of the changes in soil C and N and the origin of organic matter (through changes in δ13C) brought about by the land-use change.
