As such, VLU is a chronic disease that requires lifelong maintenance and awareness. A correct diagnosis of VLU is essential for management.

Here, downstream moving juvenile sea lamprey () were exposed to light and a conspecific chemosensory alarm cue in a flume and movement were monitored with overhead cameras and nets. When exposed to light, sea lamprey were more likely to be captured in a net closest to the light array.

We detect three bifurcation scenarios. In the first scenario, the smooth bifurcation, the regularity of the invariant torus is preserved, and the stable and unstable invariant bundles collide smoothly.
