    • Structuring dynamic models of exploited ecosystems from trophic mass-balance assessment 

      Walters, C.; Christensen, V.; Pauly, D. (1997)
      Type: Journal Article
      The linear equations that describe trophic fluxes in mass-balance, equilibrium assessments of ecosystems (such as in the ECOPATH approach) can be re-expressed as differential equations defining trophic interactions as ...

    • The climate and eastern ocean systems project 

      Bakun, A.; Christensen, V.; Curtis, C.; Cury, P.; Durand, M.H.; Husby, D.; Mendelssohn, R.; Mendo, J.; Parrish, R.; Pauly, D.; Roy, C. (1992)
      Type: Journal Article
      A brief description of the NMFS/ORSTOM/ILCARM climate and Eastern Ocean systems (CEOS) project is given. CEOS will study the four major eastern boundary current regions (Peru/Chile, California, Northwest and Southwest ...

    • The ECOPATH II software or how we can gain from working together 

      Christensen, V. (1990)
      Type: Journal Article
      Problems involved in the development of ecosystem models are discussed, considering in particular the use of the ECOPATH II software and the approach used at ICLARM in the project "Global comparisons of trophic aquatic ...

    • The South China Sea: analyzing fisheries catch data in an ecosystem context 

      Christensen, V.; Pauly, D. (1991)
      Type: Journal Article
      The South China Sea is an important fishing area with an annual harvest of some 5 million tonnes, or 10% of the catches jointly taken by the developing nations of the world. Details are given of a model of the area describing ...

    • Towards quantification of ecological sustainability in farming systems analysis 

      Dalsgaard, J.P.T.; Lightfoot, C.; Christensen, V. (1993)
      Type: Journal Article
      A tentative list of ecological attributes; diversity, cycling, stability and capacity, is proposed for quantification and ranking of farming systems along a hypothetical scale of increasing ecological sustainability. The ...

    • Trophic models of aquatic ecosystems 

      Christensen, V.; Pauly, D. (eds.) (1993)
      Type: Conference Proceedings
      A large proportion of the contributions to the ICES Theme Session on "Trophic models in aquatic ecosystems" is presented, together with papers of a number of scientists and very experienced ecosystem modellers.
