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 …

Gully erosion in India: Geo‐environmental controls and region‐specific characteristics

Anindya Majhi, Martin Evans, Emma Shuttleworth, Angela Harris

Abstract Gully erosion, which is the rapid incision of soils by concentrated overland and/or subsurface runoff, affects India widely. However, Central and Western India suffer from particularly intense land degradation as prolonged gullying has resulted in the formation of extensive badlands therein. …

‘I Health Educate, Therefore I Am’: Intrinsic Motivation and Health Education

Martin Evans

This paper concerns itself with the link between the psychological theory of intrinsic motivation and the increasing uptake of health education as a behaviour. Based on some fairly crude research done by the author and his experience over the last four years, …

Ideas and Perspectives: Potentially large but highly uncertain carbon dioxide emissions resulting from peat erosion

Thomas C. Parker, Chris Evans, Martin Evans, Miriam Glendell et autres

Peatland erosion and resulting particulate organic carbon (POC) flux is an international problem that is causing loss of peat carbon to the atmosphere and contributing to climate change. Peatlands from around the world are eroding and losing carbon for a range of …

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 …

Strength, Power, and Plyometric Training in Football

Benjamin Rosenblatt, Martin Evans

The purpose of any physical training programme in sport is to improve an athlete’s capability of excelling within the technical and tactical constraints of their sport. This involves improving the effectiveness of critical actions and also reducing the biomechanical and physiological cost …

Large cobblestone dams for natural flood management in wide peatland gullies

Adam Johnston, David Brown, Tim Allott, Salim Goudarzi et autres

Peatland restoration is increasingly used for natural flood management (NFM). In the restoration of heavily degraded blanket peatland sites, erosional gully blocking is used to capture sediment and rewet peat in smaller peat gullies. There is limited prospect for restoration of wider …

Gully erosion in India: Land degradation, geomorphology and dynamics

Anindya Majhi, Kunal Mallick, Dinabandhu Barman, Angela Harris et autres

Gully erosion is the rapid incision of soils by concentrated overland and/or subsurface runoff. Badlands, which are barren landscapes sculpted through prolonged and intense gully erosion, occur extensively across Central and Western India. These vast and immensely degraded landscapes have had several …

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 …
