Quantifying the Impact of Seismic Lines on Methane Release in a Treed Bog Ecosystem using Unmanned Aerial Vehicles (UAVs)
Peatlands are extremely complex and sensitive ecosystems, capable of releasing vast amounts of methane in response to disturbance events. To date, little advancement has been made by researchers to quantify the impact of small-scale anthropogenic disturbances on these ecosystems, specifically …

Mapping shrub biomass in a boreal continental fen
… on quantifying aboveground biomass (AGB) in peatlands. This thesis summarizes how allometric equations and unmanned aerial vehicles (UAV) can be used to map AGB across a 2-hectare peatland site. Prior to using UAVs to measure AGB, accurate field measurements are required to calibrate and …

From Genes to Traits and Ecosystems: Evolutionary Ecology of <i>Sphagnum</i> (Peat Moss)
… (peat moss) are the dominant biotic features of boreal peatlands that store nearly one-third of Earth’s terrestrial carbon. Peat mosses are ecosystem engineers and create the peatlands that they inhabit through the accumulation of peat, or partially decayed biomass, and the functional traits …

EFFECTS OF NITROGEN DEPOSITION ON BOREAL BOGS: A THREE YEAR NITROGEN FERTILIZATION AND TRACER EXPERIMENT
Boreal peatlands play important roles in global C and nutrient cycling. Oligotrophic bogs are naturally nitrogen (N) limited, receiving nutrients only via atmospheric deposition. Increased nutrient deposition, particularly N will almost certainly change the microbiology, biogeochemistry, and C and …

Phenology Effects on Carbon and Water Dynamics in a Pristine Boreal Fen A multi-decadal analysis from 2005-2007 & 2014-2022
Boreal peatlands are major constituents of the global carbon (C) and water cycles and therefore important climate regulators. These cycle dynamics are strongly determined by plant phenology (e.g.,vascular plant photosynthesis and seasonality) and evapotranspiration (ET), next to other abiotic …
