Cation responses to global changes alter ecological processes in ombrotrophic systems

Joshua Scott Lynn, Benjamin Bell, Peter Ryan, William; id_orcid 0000-0001-8918-0690 Fletcher et autres

Abstract Ombrotrophic bogs, which store large amounts of carbon as peat, receive all their mineral nutrition through deposition. This limited nutrient input means they are particularly sensitive to local and global changes that displace vital cations. We review how acid deposition drives …

The effects of drought on Sphagnum moss species and the implications for peatland carbon cycling in a changing climate

Ben Keane, Gareth D. Clay, Nina Overtoom, Jonathan P. Ritson et autres

Peatlands store more carbon (C) than any other terrestrial ecosystem and as a C sink they are vital to mitigating climate change. The keystone of many peatland ecosystems is Sphagnum, a bryophyte genus of ca. 350 species found on every continent except …

Impacts of bund construction and Sphagnum reintroduction on peatland CO₂ and CH₄ fluxes: insights from field monitoring and mesocosm experiments

Wenlue Miao, Jonathan P. Ritson, Emma Shuttleworth, Martin Evans

Peatlands are a major component of the global carbon cycle, storing large quantities of soil carbon. However, widespread drainage and land-use change have degraded many peatland systems, converting them from net carbon sinks into important sources of greenhouse gases. Water-table lowering is …

Creative interdisciplinary geographies in practice: Stitching sphagnum moss

Laura Pottinger, Anke Bernau, Abigail Bleach, Amanda Cobbett et autres

How might we get to know moss on more intimate terms? This paper outlines a creative stitching workshop as a method for facilitating interdisciplinary collaboration and for encouraging slowly paced, tactile ways of noticing and getting to know plants – in this …

The Sponge Analogy Problem: Moving Towards Clearer Communication of Peatland Hydrological Processes

Kirsten J. Lees, Colin P. R. McCarter, Jonathan P. Ritson, James Michael Waddington et autres

ABSTRACT Peatlands are important habitats that provide a range of ecosystem services, one of which is hydrological regulation. Depending on landscape position, healthy peatlands can reduce flood risk and provide resilience to drought, while degraded peatlands can exacerbate these hydrological disturbances. There …

The effects of drought on Sphagnum moss species and the implications for hydrology in peatlands

Ben Keane, Danielle M. Alderson, Gareth D. Clay, Martin Evans et autres

Summary Peatlands store more carbon (C) than any other terrestrial ecosystem and as a C sink they are vital to mitigating climate change. The keystone of many peatland ecosystems is Sphagnum , a bryophyte genus of c . 350 species found on …

Recovery of Sphagnum from drought is controlled by species-specific moisture thresholds

Ben Keane, Emma Shuttleworth, Martin Evans, Jonathan P. Ritson et autres

Abstract As the largest terrestrial carbon (C) store, peatlands are vital to meeting climate targets. Sphagnum, a genus of ca. 350 species, sustains many peatlands through its high water content and chemistry which inhibits decomposition and vascular plant proliferation. However, many peatlands …

The resilience and recovery of two globally important Sphagnum species to drought

Ben Keane, Gareth D. Clay, Emma Shuttleworth, Martin Evans et autres

Sphagnum mosses are key to peatland functioning and C cycling. They may cover 80- 100% of peatland land area and make up the vast majority of the peat itself. Sphagnum chemistry slows decomposition, enabling organic material accumulation which forms peat; it holds …

Climate change impacts on blanket peatland in Great Britain

Jonathan P. Ritson, Kirsten J. Lees, James Hill, Angela V. Gallego-Sala et autres

Abstract Peatland restoration has been suggested as a key method for the UK to meet national, legally binding climate targets. This can involve blocking up drainage ditches or erosion features, as well as encouraging regeneration of peatland vegetation through Sphagnum reintroduction or …

The formation of peat—Decreasing density with depth in UK peats

Fred Worrall, Gareth D. Clay, Katherine Heckman, Jonathan P. Ritson et autres

Abstract Increasing bulk density with depth in a peat profile has been seen as key to the formation of peat. Increasing bulk density with depth causing the changes in porosity and permeability of peat soils has been proposed as a mechanism to …
