title: Data from: Long-term climate and hydrologic regimes shape stream invertebrate community responses to a hurricane disturbance

description: Disturbances can produce a spectrum of short- and long-term ecological
 consequences that depend on complex interactions of the characteristics of
 the event, antecedent environmental conditions, and the intrinsic
 properties of resistance and resilience of the affected biological system.
 We used Hurricane Harvey’s impact on coastal rivers of Texas to examine
 the roles of storm-related changes in hydrology and long-term
 precipitation regime on the response of stream invertebrate communities to
 hurricane disturbance. We detected declines in richness, diversity, and
 total abundance following the storm, but responses were strongly tied to
 direct and indirect effects of long-term aridity and short-term changes in
 stream hydrology. The amount of rainfall a site received drove both flood
 duration and flood magnitude across sites, but lower annual rainfall
 amounts (i.e., aridity) increased flood magnitude and decreased flood
 duration. Across all sites, flood duration was positively related to the
 time it took for invertebrate communities to return to a long-term
 baseline and flood magnitude drove larger invertebrate community responses
 (i.e., changes in diversity and total abundance). However, invertebrate
 response per unit flood magnitude was lower in sub-humid sites,
 potentially because of differences in refuge availability or
 ecological-evolutionary interactions. Interestingly, sub-humid streams had
 temporary large peaks in invertebrate total abundance and diversity
 following recovery period that may be indicative of the larger organic
 matter pulses expected in these systems because of their comparatively
 well-developed riparian vegetation. Our findings show that hydrology and
 long-term precipitation regime predictably affected invertebrate community
 responses and, thus, our work underscores the important influence of local
 climate to ecosystem sensitivity to disturbances.
