Temporal heterogeneity increases with spatial heterogeneity in ecological communities.

abstract：:Previous work suggests that animal water balance can influence trophic interactions, with predators increasing their consumption of water-laden prey to meet water demands. But it is unclear how the need for water interacts with the need for energy to drive trophic interactions under shifting conditions. Using manipula...
