    Malhi, Y; Metcalfe, DB; Silva-Espejo, JE; Jiménez, E; Navarrete, D; Almeida, S; Costa, ACL; Salinas, N; Phillips, OL; Anderson, LO; Alvarez, E; Baker, TR; Goncalvez, PH; Huamán-Ovalle, J; Mamani-Solórzano, M; Meir, P; Monteagudo, A; Patĩo, S; Peñuela, MC; Prieto, A; Quesada, CA; Rozas-Dávila, A; Rudas, A; Silva Jr, JA; Vásquez, R; Aragao, Luiz (European Geosciences Union (EGU), 2009)
    The net primary productivity (NPP) of tropical forests is one of the most important and least quantified components of the global carbon cycle. Most relevant studies have focused particularly on the quantification of the ...

  • After the Anthropocene: Politics and geographic inquiry for a new epoch 

    Johnson, ER; Morehouse, H; Dalby, S; Lehman, J; Nelson, S; Rowan, R; Wakefield, S; Yusoff, K (SAGE Publications Ltd, 2014-02-07)
    Crutzen and Stoermer's (2000) naming of the 'Anthropocene' has provoked lively debate across the physical and social sciences, but, while the term is gradually gaining acceptance as the signifier of the current geological ...
  • The age of CO2 released from soils in contrasting ecosystems during the arctic winter 

    Hartley, IP; Garnett, MH; Sommerkorn, M; Hopkins, DW; Wookey, PA (Elsevier, 2013)
    In arctic ecosystems, winter soil respiration can contribute substantially to annual CO2 release, yet the source of this C is not clear. We analysed the 14C content of C released from plant-free plots in mountain birch ...
  • Agricultural change and farm incomes in Devon: an update 

    Robbins, Keith; Butler, Allan; Turner, Martin; Lobley, Matt (Centre for Rural Policy Research, University of Exeter, 2006-06)
  • Agricultural restructuring: the potential role of joint venture arrangements 

    Turner, Martin; Hambly, John (Centre for Rural Policy Research, University of Exeter, 2005-01)
  • Anticipating ubiquitous computing: Logics to forecast technological futures 

    Kinsley, Samuel (Elsevier, 2011-03)
    Visions of the future predict spaces apparently teaming with ever more novel and pervasive technologies. Significant amongst such forecasts is the notion of ‘ubiquitous computing’ (ubicomp), understood as an affordance or ...
  • Arguably big biology: Sociology, spatiality and the knockout mouse project 

    Davies, Gail (Palgrave Macmillan, 2013-12)
    Following the completion of the Human Genome Project (HGP), a critical challenge has been how to make biological sense of the amassed sequence data and translate this into clinical applications. A range of large biological ...
  • Atmospheres of progress in a data-based school 

    Finn, M (SAGE Publications, 2015-03-23)
    In this article, I seek to extend the geographies of education, youth and young people by offering an account of the significant shifts taking place in contemporary English state education around the production and use of ...
  • Biomimetic Futures: Life, Death, and the Enclosure of a More-Than-Human Intellect 

    Johnson, ER; Goldstein, J (Routledge, 2015-03-04)
    The growing field of biomimicry promises to supplant modern industry's energy-intensive models of engineering with a mode of production more sensitively attuned to nonhuman life and matter. This article considers the ...
  • Biomimicry: New Natures, New Enclosures 

    Goldstein, J; Johnson, ER (SAGE Publications Ltd, 2015-01-16)
    Advocates of biomimicry encourage a new industrial paradigm that ostensibly leaves behind the crude violence of Francis Bacon, the domination of nature-as-machine, and a history of toxic production processes that have given ...
  • The biopolitics of animal being and welfare: dog control and care in the UK and India 

    Srinivasan, K (Institute of British Geographers / Royal Geographical Society / Wiley-Blackwell, 2013-01)
