Using a new generation of high tech tags, like the SMART collar worn by this mountain lion (Photo Credit: Sebastian Kennerknecht/pumapix.com), scientists are discovering that the world is becoming an energetically challenging place to live for large carnivores, as discussed in Williams et al's Calow‐Grace Review, “Hunters versus Hunted: New perspectives on the energetic costs of survival at the top of the food chain” (Funct Ecol. 34: 2015‐2029, https://doi.org/10.1111/1365-2435.13649)
