Abstract: Energy and habitat distribution are inherently linked. Energy is a major driver of the distribution of consumers, but estimating how much specific habitats contribute to the energetic needs of a consumer can be problematic. We present a new approach that combines remote sensing information and stable isotope ecology to produce maps of energetic resources (E-scapes). E-scapes project species specific resource use information onto the landscape to classify areas based on energetic importance and successfully predict the biomass and energy density of a consumer in salt marsh habitats in coastal Louisiana, USA. Our E-scape maps can be used alone or in combination with existing models to improve habitat management and restoration practices and have potential to be used to test fundamental movement theory.
