  • Broad Down, Devon: archaeological and other stories 

    Harvey, David (Sage, 2010)
    This article explores the knowledge construction process of an archaeological site in East Devon, UK. Bouncing off an oral historical account of the site that seems to run against scientific truth claims, the author ...
  • Carbon and nutrient accumulation in secondary forests regenerating on pastures in central Amazonia 

    Feldpausch, TR; Rondon, MA; Fernandes, ECM; Riha, SJ; Wandelli, E (Ecological Society of America, 2004)
    Over the past three decades, large expanses of forest in the Amazon Basin were converted to pasture, many of which later degraded to woody fallows and were abandoned. While the majority of tropical secondary forest (SF) ...
  • The carbon balance of South America: A review of the status, decadal trends and main determinants 

    Gloor, M; Gatti, L; Brienen, R; Feldpausch, TR; Phillips, OL; Miller, J; Ometto, JP; Rocha, H; Baker, T; De Jong, B; Houghton, RA; Malhi, Y; C Aragão, LEO; Guyot, J-L; Zhao, K; Jackson, R; Peylin, P; Sitch, S; Poulter, B; Lomas, M; Zaehle, S; Huntingford, C; Levy, P; Lloyd, J (European Geosciences Union (EGU), 2012)
    We attempt to summarize the carbon budget of South America and relate it to its dominant controls: population and economic growth, changes in land use practices and a changing atmospheric environment and climate. Flux ...
  • Carbon dynamics of the Weddell Gyre, Southern Ocean 

    Brown, PJ; Jullion, L; Landschützer, P; Bakker, DCE; Naveira Garabato, AC; Meredith, MP; Torres-Valdés, S; Watson, Andrew J.; Hoppema, M; Loose, B; Jones, EM; Telszewski, M; Jones, SD; Wanninkhof, R (Blackwell Publishing Ltd, 2015-03-19)
    The accumulation of carbon within the Weddell Gyre and its exchanges across the gyre boundaries are investigated with three recent full-depth oceanographic sections enclosing this climatically important region. The combination ...
  • Caribbean-wide decline in carbonate production threatens coral reef growth. 

    Perry, CT; Murphy, GN; Kench, PS; Smithers, SG; Edinger, EN; Steneck, RS; Mumby, PJ (Nature Publishing Group, 2013-01-29)
    Global-scale deteriorations in coral reef health have caused major shifts in species composition. One projected consequence is a lowering of reef carbonate production rates, potentially impairing reef growth, compromising ...
  • Caring for the collective: biopower and agential subjectification in wildlife conservation 

    Srinivasan, K (Pion, 2014-06)
    This paper explores turtle conservation in Odisha, India, to map the complicated ways in which animal well-being is pursued in the contemporary world. Using insights from Foucault’s work on biopolitics, it offers an account ...
  • Caring for the multiple and the multitude: assembling animal welfare and enabling ethical critique 

    Davies, Gail (Pion, 2012)
    This paper constitutes a speculative bioethical intervention into the challenge of developing cultures of care and assembling enriched environments for genetically altered mice in laboratory environments. The principles ...
  • Centennial climate variability in the British Isles during the mid-late Holocene 

    Charman, DJ (Elsevier, 2010-06)
    Multi-millennial climate changes were relatively minor over the mid–late Holocene in the British Isles, because orbitally forced insolation changes were smaller than those at higher latitudes. Centennial climate variability ...
  • Challenging the 'view from nowhere': citizen reflections on specialist expertise in a deliberative process. 

    Davies, Gail; Burgess, J (Elsevier, 2004-12)
    This paper presents analysis of citizen encounters with specialists in a deliberative process, called Deliberative Mapping, which explored options for addressing the shortage of organs for transplantation in the UK. There ...
  • Changes in hydrology and erosion over a transition from grassland to shrubland 

    Turnbull, Laura; Wainwright, John; Brazier, Richard E. (Wiley-Blackwell, 2010-02-15)
    The degradation of grasslands is a common problem across semi-arid areas worldwide. Over the last 150 years, much of the south-western United States has experienced significant land degradation, with desert grasslands ...
  • Changing tectonic controls on the long-term carbon cycle from Mesozoic to present 

    Mills, Benjamin; Daines, Stuart; Lenton, Timothy M. (Wiley/AGU, 2014-12-17)
    Tectonic drivers of degassing and weathering processes are key long-term controls on atmos- pheric CO2. However, there is considerable debate over the changing relative importance of different car- bon sources and sinks. ...
  • Changing UK river temperatures and their impact on fish populations 

    Webb, B.W.; Walsh, A.J. (British Hydrological Society, 2004)
  • Chronologies for recent peat deposits using wiggle-matched radiocarbon ages: problems with old carbon contamination 

    Charman, Dan, J; Garnett, Mark, H (University of Arizona, 2005)
    Dating sediments which have accumulated over the last few hundred years is critical to the calibration of longer-term paleoclimate records with instrumental climate data. We attempted to use wiggle-matched radiocarbon ages ...
  • Climate change and visual imagery 

    O'Neill, SJ; Smith, N (Royal Meteorological Society / Royal Geographical Society / Wiley, 2014-02)
    Many actors—including scientists, journalists, artists, and campaigning organizations—create visualizations of climate change. In doing so, they evoke climate change in particular ways, and make the issue meaningful in ...
  • Climate drivers for peatland palaeoclimate records 

    Charman, Dan, J; Barber, Keith E.; Blaauw, Maarten; Langdon, Pete G.; Mauquoy, Dmitri; Daley, Tim J.; Hughes, Paul D.M.; Karofeld, Edgar (Elsevier Ltd, 2009-09)
    Reconstruction of hydroclimate variability is an important part of understanding natural climate change on decadal to millennial timescales. Peatland records reconstruct ‘bog surface wetness’ (BSW) changes, but it is unclear ...
  • Climate-related changes in peatland carbon accumulation during the last millennium 

    Charman, DJ; Beilman, DW; Blaauw, M; Booth, RK; Brewer, S; Chambers, FM; Christen, JA; Gallego-Sala, A; Harrison, SP; Hughes, PDM; Jackson, ST; Korhola, A; Mauquoy, D; Mitchell, FJG; Prentice, IC; Van Der Linden, M; De Vleeschouwer, F; Yu, ZC; Alm, J; Bauer, IE; Corish, YMC; Garneau, M; Hohl, V; Huang, Y; Karofeld, E; Le Roux, G; Loisel, J; Moschen, R; Nichols, JE; Nieminen, TM; MacDonald, Glen M.; Phadtare, NR; Rausch, N; Sillasoo, U; Swindles, GT; Tuittila, E-S; Ukonmaanaho, L; Väliranta, M; Van Bellen, S; Van Geel, B; Vitt, DH; Zhao, Y (European Geosciences Union (EGU), 2013)
    Peatlands are a major terrestrial carbon store and a persistent natural carbon sink during the Holocene, but there is considerable uncertainty over the fate of peatland carbon in a changing climate. It is generally assumed ...
