  • Aerial photography collected with a multirotor drone reveals impact of Eurasian beaver reintroduction on ecosystem structure 

    Puttock, A; Cunliffe, AM; Anderson, K; Brazier, Richard E. (NRC Research Press, 2015-04-29)
    Beavers are often described as ecological engineers with an ability to modify the structure and flow of fluvial systems and create complex wetland environments with dams, ponds and canals. Consequently, beaver activity has ...
  • 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

  • Animal Geographies III: Ethics 

    Buller, HJ (SAGE Publications, 2015-04-19)
    There is no animal geography without ethics. The very coupling of the words gives rise to an ethical endeavor; an acceptance that animals have a geography, a making visible of animals within our human geography and ...
  • Antecedent conditions control carbon loss and downstream water quality from shallow, damaged peatlands. 

    Grand-Clement, Emilie; Luscombe, David J; Anderson, K; Gatis, Naomi; Benaud, P; Brazier, Richard E. (Elsevier, 2014-09-15)
    Losses of dissolved organic carbon (DOC) from drained peatlands are of concern, due to the effects this has on the delivery of ecosystem services, and especially on the long-term store of carbon and the provision of drinking ...

  • 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 ...
