A SOCIAL-ECOGICAL INVESTIGATION OF RIVERINE HABITAT COMPLEXITY: INSECT EMERGENCE, TERRESTRIAL INSECTIVORES, AND PUBLIC PERCEPTIONS
Emergence of adult aquatic insects constitutes a resource flux that can influence a suite of terrestrial insectivores, and the timing, magnitude, and composition of these aquatic–terrestrial fluxes can vary considerably in space. Thus, spatial complexity of riverine habitats (or, reciprocally, their homogenization) may influence numerous terrestrial organisms, but these relationships are poorly understood. We conducted a comparative study during summer of 2016 to investigate the effect of spatial heterogeneity on the emergence of aquatic insects, and subsequent consequences for terrestrial predators (using spiders and bats as indicator species) on the Portneuf River in southeast Idaho. Additionally, we administered a social survey assessing public perceptions of habitat complexity to better understand the ways in which people might support or oppose restoration efforts. Although our ecological study demonstrated that complex habitats support greater fluxes of insect emergence and increased densities of riparian spiders, the results of the social survey revealed a potential mismatch. While citizens generally recognized the ecological importance of heterogeneity, they tended to exhibit preference for only moderately complex river systems. Our findings provide a direct, locally relevant basis to inform and adapt restoration efforts planned for the Portneuf River.
