    • Full annual cycle bioenergetics model of migration applied to Galapagos tortoises—Data

    Metadata Updated: July 6, 2024

    Ambient-shade temperature was measured every 4 h with iButton thermochrons (Maxim Integrated Products, Inc., Sunnyville, CA, USA) placed at 1m above-ground level for a previous paper (Blake et al., 2012 – DOI 10.1111/1365-2656.12020). The Normalized Difference Vegetation Index (NDVI) of the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument (Huete et al. 2002 - http://dx.doi.org/10.1016/S0034-4257(02)00096-2) was used as an index of vegetation quantity. Monthly average NDVI values within the range of each tortoise population were derived based on grid sampling within the convex hull created by upland and lowland relocations of migratory individuals during their sedentary (non-migratory) phases of movement. We linearly interpolated between monthly values to create daily values. The other data (hmat) is a matrix with the time of data corresponding to the temperature data. All data cover the period Feb. 1, 2010 to Jan. 31, 2011 and were originally presented in Blake et al. (2012 – DOI 10.1111/1365-2656.12020), but are required for the model presented here.
