(Re)Defining Ecosystems
Ecosystems are inherently dynamic and so is our understanding of them. The concept of ecosystems has evolved over time, shaped by the cumulative effect of shifts in scientific paradigms, methodological advancements, environmental concerns and socio‐political interests. This article examines how the Colombian páramos, a high‐elevation mountain ecosystem, have been redefined multiple times through different delimitations, each reflecting a differen…
From Holocene stability to industrial acceleration
Lakes play a crucial role in the continental carbon cycle by burying large amounts of terrestrial organic matter in their sediments. Recent increases in carbon accumulation rates (CAR) have been linked to anthropogenic climate and land-use changes. However, the extent to which modern CAR exceeds naturally varying Holocene trends remains unclear because of a lack of datasets combining long-term and recent CAR records with consistent sediment prope…
Hydrology controls thermokarst and alters carbon cycling and methane emissions in peatlands near the southern limit of permafrost
Permafrost peatlands store vast amounts of frozen carbon across northern landscapes. When ground ice melts, surface subsidence produces thermokarst landforms that expand wetlands at the edges of permafrost plateaus. Thermokarst represents an accelerating climate feedback, but uncertainties remain about how ground ice, hydrology, and vegetation interact to shape landscape change and carbon fluxes. We extended the process-based model ecosys to simu…
The unrecognized importance of carbon stocks and fluxes from swamps in Canada and the USA
Swamps are a highly significant wetland type in North America both in terms of areal extent and their role in terrestrial carbon cycling. These wetlands, characterized by woody vegetation cover, encompass a diverse suite of ecosystems, including broad-leaved, needle-leaved, mixedwood or shrub/thicket swamps. Uncertainties in the role of swamps in carbon uptake and release continue to be substantial due to insufficient data on variabilities in car…
Geographic versus institutional drivers of nitrogen footprints
Excess reactive nitrogen (N) is linked to a myriad of environmental problems that carry large social costs. Nitrogen footprint tools can help institutions understand how their direct and indirect activities are associated with N release to the environment through energy use, food, and transportation. However, little is known about how geographic context shapes the environmental footprints of institutions. Defining the system boundaries over which…
The environmental footprint of academic and student mobility in a large research-oriented university
Academic mobility for field work, research dissemination and global outreach is increasingly recognized as an important contributor to the overall environmental footprint of research institutions. Student mobility, while less studied, also contributes to universities’ environmental footprint. Université de Montréal (UdeM) is the largest university in Montréal, Canada. It has a research budget of 450M$, employs 1426 full-time professors, and has a…
Influence of Holocene permafrost aggradation and thaw on the paleoecology and carbon storage of a peatland complex in northwestern Canada
Permafrost in peatlands strongly influences ecosystem characteristics, including vegetation composition, hydrological functions, and carbon cycling. Large amounts of organic carbon are stored in permafrost peatlands in northwestern Canada. Their possible degradation into permafrost-free wetlands including thermokarst bogs may affect carbon (C) stocks, but the direction and magnitude of change are uncertain. Using peat core reconstructions, we cha…
The cascade of C
Northern peatlands are important carbon (C) sinks and while the patterns of C accumulation have been frequently investigated, nitrogen (N) and phosphorus (P) accumulation are often neglected. Here we link the C:N:P stoichiometry from foliar plant tissues, through senescent litters to peat, and determine C, N and P accumulation rates at Mer Bleue Bog, eastern Canada. Average C:N:P ratios changed from 794:17:1 in the foliar tissues to 911:10:1 in l…
Exploring the relationship between peatland net carbon balance and apparent carbon accumulation rate at century to millennial time scales
Each year, a peatland has an annual net carbon balance ( NCB), which can be positive (net uptake), zero or negative. Over centuries to millennia, this NCB accumulates as a peat profile. Contemporary peatlands can be sampled (cored), and the past apparent carbon accumulation rate ( aCAR) can be determined as the quantity of peat carbon in any particular dated interval down the core profile. We use a process-based peatland carbon and water cycle mo…
