  • Andean grasslands are as productive as tropical cloud forests 

    Oliveras, I.; Girardin, C.; Doughty, C. E.; Cahuana, N.; Arenas, C. E.; Oliver, V.; Huasco, W. Huaraca; Malhi, Y. (2014-11) - Journal article
    We aim to assess net primary productivity (NPP) and carbon cycling in Andean tropical alpine grasslands (puna) and compare it with NPP of tropical montane cloud forests. We ask the following questions: (1) how do NPP and ...
  • The anthropogenic influence on wildfire regimes : charcoal records from the Holocene and Last Interglacial at Ioannina, Greece 

    Lawson, I. T.; Tzedakis, P. C.; Roucoux, K. H.; Galanidou, N. (2013-12) - Journal article
    Aim: To characterize the changing fire regime of a Mediterranean landscape during the Holocene and the Last Interglacial and, by comparing the two periods, to improve our understanding of the extent and timing of human ...
  • The distribution and amount of carbon in the largest peatland complex in Amazonia 

    Draper, Frederick; Roucoux, Katherine Helen; Lawson, Ian Thomas; Mitchard, Edward; Honorio Coronado, Euridice; Lahteenoja, Outi; Torres Montenegro, Luis; Valderrama Sandoval, Elvis; Zarate, Ricardo; Baker, Timothy (2014-12) - Journal article
    Peatlands in Amazonian Peru are known to store large quantities of carbon, but there is high uncertainty in the spatial extent and total carbon stocks of these ecosystems. Here, we use a multi-sensor (Landsat, ALOS PALSAR ...
  • Human impact on an island ecosystem : pollen data from Sandoy, Faroe Islands 

    Lawson, Ian T.; Edwards, Kevin J.; Church, Mike J.; Newton, Anthony J.; Cook, Gordon T.; Gathorne-Hardy, Freddy J.; Dugmore, Andrew J. (2008-06) - Journal article
    Aim To investigate the form and dynamics of ecosystems on an isolated island in the North Atlantic before human settlement in the first millennium AD, and the effects of human activities thereafter. Location The island of ...
  • Optimizing sampling design to deal with mist-net avoidance in Amazonian birds and bats 

    Marques, Joao Tiago; Ramos Pereira, Maria J.; Marques, Tiago A.; Santos, Carlos David; Santana, Joana; Beja, Pedro; Palmeirim, Jorge M. (2013-09-18) - Journal article
    Mist netting is a widely used technique to sample bird and bat assemblages. However, captures often decline with time because animals learn and avoid the locations of nets. This avoidance or net shyness can substantially ...
  • Peat initiation in the Faroe Islands : climate change, pedogenesis or human impact? 

    Lawson, Ian T.; Church, Mike J.; Edwards, Kevin J.; Cook, Gordon T.; Dugmore, Andrew J. (2007-03) - Journal article
    As an isolated island group lying off the NW. European mainland which was uninhabited until the mid-first millennium AD, the Farces offer a unique opportunity to study natural processes of Holocene ecosystem development ...
  • Rapid primary productivity changes in one of the last coastal rainforests : the case of Kahua, Solomon Islands 

    Garonna, Irene; Fazey, Ioan Raymond Albert; Brown, Molly E.; Pettorelli, Nathalie (2009-09) - Journal article
    The growth of human populations has many direct and indirect impacts on tropical forest ecosystems both locally and globally. This is particularly true in the Solon-ion Islands, where coastal rainforest cover still remains, ...
