Energetic resources and habitat distribution are inherently linked. Energetic resource availability is a major driver of the distribution of consumers, but estimating how much specific habitats contribute to the energetic resource 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.
Using our E-scapes, we investigated the relationship between energetic resource distribution and white shrimp distribution and how the scale used to generate the E-scape mediated this relationship.
E-scapes successfully predicted the size, abundance, biomass, and total energy of a consumer in salt marsh habitats in coastal Louisiana, USA at scales relevant to the movement of the consumer.
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.

E-scape：来自稳定同位素分析和遥感的能源资源的消费者特定景观

能源资源和栖息地分布具有内在联系。能源资源的可用性是消费者分布的主要驱动力，但估计特定栖息地对消费者能源资源需求的贡献可能是有问题的。
我们提出了一种将遥感信息和稳定同位素生态相结合的新方法，以生成能量资源图（E -scapes）。E -scapes 将特定物种的资源使用信息投射到景观上，以根据能源重要性对区域进行分类。
使用我们的E -scapes，我们研究了能量资源分布和白虾分布之间的关系，以及用于生成E -scape 的尺度如何调节这种关系。
E -scapes 成功地预测了美国路易斯安那州沿海盐沼栖息地中消费者的规模、丰度、生物量和总能量，其规模与消费者的运动相关。
我们的E -scape 地图可以单独使用，也可以与现有模型结合使用，以改善栖息地管理和恢复实践，并有可能用于测试基本运动理论。
