r_90mir85_snd: 9-second gridded continental Australia composite ecological change for Reptiles 1990:2050 MIROC5 RCP 8.5 (CMIP5) (GDM: REP_R3_V2)


Composite ecological change as a function of three metrics (the potential degree of ecological change and of disappearing and novel ecological environments) shows where change might be greatest and different types of vulnerability using 30-year climate averages between the present (1990:1976- 2005) and projected future (2050:2036-2065) under the MI... more

Ecological similarity ranges between 0 and 1: the closer to zero, the greater the potential for compositional change in biodiversity. Each of the three ecological similarity measures were rescaled between 0 and 255 as integers to match the RGB colour scale, but the Potential degree of ecological change measure was inverted first (1-0 rescaled 0-255). Using the Composite Bands tool in ArcGIS 10.2.2, a three-band raster was created with band1 = similarity, S; band 2 = novel, N; and band 3 = disappearing, D. In ArcGIS mapping symbology, each of the three component measures are then assigned to a colour band: RED channel = BAND_3 (Disappearing) GREEN channel = BAND_1 (Similarity) BLUE channel = BAND_2 (Novel) The gamma stretch legend scaling is not used and the min-max legend stretch is applied with statistics defined from the same custom settings for each band: minimum = 0; maximum= 255, mean = 126, std = 0. These settings correctly reproduce the colours. The composite ecological change index derives from the following three measures that are elsewhere described: 1. S, similarity: 9-second gridded continental Australia potential degree of ecological change for Reptiles 1990:2050 MIROC5 RCP 8.5 (CMIP5) (GDM: REP_R3_V2) 2. N, novel: 9-second gridded continental Australia novel ecological environments for Reptiles 1990:2050 MIROC5 RCP 8.5 (CMIP5) (GDM: REP_R3_V2) 3. D, dissimilarity: 9-second gridded continental Australia disappearing ecological environments for Reptiles 1990:2050 MIROC5 RCP 8.5 (CMIP5) (GDM: REP_R3_V2) More detail of the calculations and methods used to derive the individual measures are given in the document “9sMethodsSummary.pdf” provided with the data download. Each of these three measures use the GDM model that is elsewhere described: Generalised dissimilarity model of compositional turnover in reptile species for continental Australia at 9 second resolution using ANHAT data extracted 4 April 2013 (GDM: REP_R3_V2) Climate data. Generalised dissimilarity models were built and projected using climate data that are elsewhere described: 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 A brief summary of the climate downscaling method is given in the document “9sMethodsSummary.pdf” provided with the data download.

Mean States, Variability, and Climate Sensitivity’, JOURNAL of CLIMATE 23(23), 6312-6335, doi:10.1173/2010JCLI3679.1


The metric is described in the AdaptNRM Guide “Implications of Climate Change for Biodiversity: a community-level modelling approach”, available online at: www.adaptnrm.org. The lineage identifies six datasets that are elsewhere described: html links for those datasets are given in the related materials.

1173.3 WPC Global Protected Area Assessm


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

Biodiversity Impact Analyses


This activity brings together the modelled patterns of species compositional turnover over time with the contextual land use data layers to estimate a range of metrics of projected change for biodiversity for all locations in Australia. The magnitude and character of climatic changes are described for each cell, based on the overall (whole landscap... more
