  • Carbon loss by water erosion in drylands: Implications from a study of vegetation change in the south-west USA 

    Brazier, Richard E.; Turnbull, Laura; Wainwright, John; Bol, Roland (Wiley, 2013-03-26)
    Soil organic carbon (SOC) is an important component of the global carbon cycle yet is rarely quantified adequately in terms of its spatial variability resulting from losses of SOC due to erosion by water. Furthermore, in ...
  • Caribbean-wide decline in carbonate production threatens coral reef growth 

    Perry, Chris T.; Murphy, Gary N.; Kench, Paul S.; Smithers, Scott G.; Edinger, Evan N.; Steneck, Robert S.; Mumby, Peter J. (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, Dan J. (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 ...
  • Century-scale simulations of the response of the West Antarctic Ice Sheet to a warming climate 

    Cornford, Stephen Leslie; Martin, DF; Payne, AJ; Ng, EG; Le Brocq, A.M.; Gladstone, RM; Edwards, TL; Shannon, SR; Agosta, C; Van Den Broeke, MR; Hellmer, HH; Krinner, G; Ligtenberg, SRM; Timmermann, R; Vaughan, DG (Copernicus GmbH, 2015-08-18)
    We use the BISICLES adaptive mesh ice sheet model to carry out one, two, and three century simulations of the fast-flowing ice streams of the West Antarctic Ice Sheet, deploying sub-kilometer resolution around the grounding ...
  • 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 dynamics of Caribbean reef carbonate budgets: emergence of reef bioeroders as critical controls on present and future reef growth potential 

    Perry, Chris T.; Steneck, Robert S.; Murphy, Gary N.; Kench, Paul S.; Edinger, Evan N.; Smithers, Scott G.; Mumby, Peter J. (Royal Society, 2014-10-15)
    Coral cover has declined rapidly on Caribbean reefs since the early 1980s, reducing carbonate production and reef growth. Using a cross-regional dataset, we show that widespread reductions in bioerosion rates—a key carbonate ...
  • 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 ...
  • Civic geographies: pictures and other things at an exhibition 

    Philo, C.; Askins, Kye; Cook, Ian (University of British Columbia, Okanagan, 2015)
