Body Size and Local Density Explain Movement Patterns in Stream Fishes.

ABSTRACT: Movement is a fundamental process in structuring communities, distributing species, and mediating gene flow. Both extrinsic (e.g., density of species) and intrinsic factors (e.g., body size) influence movement patterns, ultimately driving the spatial organization of ecological communities. However, these extrinsic and intrinsic factors are often assessed in isolation, limiting our ability to understand how multiple factors combine to shape movement patterns in nature. Here, we evaluate whether body size (intrinsic) and intra- and interspecific densities (extrinsic) have an impact on the movement rates of four fish species (Nocomis leptocephalus bluehead chub, Semotilus atromaculatus creek chub, Lepomis cyanellus green sunfish, and L. auritus redbreast sunfish) i
