  • Biosecurity and the topologies of infected life: From borderlines to borderlands 

    Hinchliffe, S; Allen, John; Lavau, S; Bingham, N; Carter, S (Wiley / Institute of British Geographers / Royal Geographical Society, 2012-08-10)
    Biosecurity, as a response to threats from zoonotic, food-borne and emerging infectious diseases, implies and is often understood in terms of a spatial segregation of forms of life, a struggle to separate healthy life from ...
  • Biotic and abiotic changes in ecosystem structure over a shrub-encroachment gradient in the southwestern USA. 

    Turnbull, Laura; Brazier, Richard E.; Wainwright, John; Bol, Roland (Springer Verlag, 2010)
    In this study, we investigate changes in ecosystem structure that occur over a gradient of land-degradation in the southwestern USA, where shrubs are encroaching into native grassland. We evaluate a conceptual model which ...

    Repeat-pass ICESat altimetry has revealed 124 discrete surface height changes across the Antarctic Ice Sheet, interpreted to be caused by subglacial lake discharges (surface lowering) and inputs (surface uplift). Few of ...
  • Carbon and nutrient accumulation in secondary forests regenerating on pastures in central Amazonia 

    Feldpausch, T.R.; Rondon, MA; Fernandes, Erick; 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

    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, 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 ...
  • 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 ...
  • 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. ...

    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 ...
