THE ROLE OF NESTING MINNOWS FOR MODIFYING THE BENTHOSCAPE
Fishes can be important ecosystem engineers in streams. Numerous minnow (Leuciscidae) species modify substrate by constructing nests for spawning. Nocomis chubs carry stones in their months to construct large gravel mounds. Chubs have been documented moving stones up to 25 m each. These nests are unique features on the benthoscape, and are oftentimes the only source of concentrated, unsilted gravel in local habitats. In this study, we aim to quantify (a) the amount of benthic habitat modified by nesting male Bluehead Chubs N. leptocephalus in streams of varying gravel availability, and (b) the role of chubs for upstream and downstream gravel transport. We will measure available and modified substrate throughout the spawning season, and will quantify transport by monitoring marked (painted and PIT-tagged) stones. Preliminary results will be reported.
