9-second gridded continental Australia need for assisted dispersal (50% similarity) for Mammals 1990:2050 MIROC5 RCP 8.5 (CMIP5) (GDM: MAM_r2)


Need for assisted dispersal for Mammals as a function of change in long term (30 year average) climates between the present (1990 centred) and projected future (2050 centred) under the MIROC5 model (RCP 8.5) based on Generalised Dissimilarity Modelling (GDM) of compositional turnover. The distance to the nearest grid cell with ecological similarit... more

Need for assisted dispersal was calculated calculated using the highly parallel bespoke CSIRO Muru software running on a LINUX high-performance-computing cluster, taking GDM model transformed environmental grids as inputs. The distance to the nearest future cell with an ecological similarity > 0.5 to the present cell was calculated. More detail of the calculations and methods are given in the document “BiodiversityModellingMethodsSummary.pdf” provided with the data download. GDM Model: Generalised dissimilarity model of compositional turnover in mammal species for continental Australia at 9 second resolution using ALA data extracted 27 February 2014 (GDM: MAM_r2) Climate data. Models were built and projected using: a) 9-second gridded climatology for continental Australia 1976-2005: Summary variables with elevation and radiative adjustment b) 9-second gridded climatology for continental Australia 2036-2065 MIROC5 RCP 8.5 (CMIP5): Summary variables with elevation and radiative adjustment

About this Project

1173.3 Strat: WPC Global Prot Area Ass


This project employs macroecological modelling and analysis techniques pioneered by CSIRO to assess present and future representation of terrestrial biodiversity within the world’s protected-area system. The project aims to address four main questions: 1. How adequately does the world’s protected-area system represent current patterns of compositio... more
