Comparing effects of auditory and visual disturbances on smallmouth bass parental care behaviors during the summer of 2025 at Douglas Lake, Michigan, USA
A prevalent source of sensory pollution within aquatic systems is recreational motorboats that can impact aquatic organisms through several exposure mechanisms. Auditory and visual sensory disturbances are particularly important as fish may utilize these cues during critical reproductive behaviors such as parental care. Here, we conducted a field study in Douglas Lake, Michigan, and located wild smallouth bass nests actively guarded by males. We exposed smallmouth bass to two sequential treatments of playback auditory noise and visual disturbances. Using an underwater drone, parental care behaviors of smallmouth bass were monitored before, during, and after both auditory and visual disturbances. The results show that auditory and visual disturbances may alter smallmouth bass parental care behaviors differently.

Negative effect of turbidity on prey capture for both visual and non-visual aquatic predators
<p>1. Turbidity plays an important role in aquatic predator-prey interactions. Increases in turbidity are expected to reduce prey capture rates, especially for visually oriented predators. However, there is also evidence indicating that turbidity may have little or no effect on predation rates. 2. Here, we conducted a systematic review and meta-analysis of the relationship between turbidity and capture rate. We explored possible sources of heterogeneity in the effect sizes (capture strategy, predator's body size, relative eye size and turbidity range in the experiments) while controlling for the dependence among effects sizes and phylogenetic relationships among predator species. 3. We found a consistent negative effect of turbidity on prey capture and that turbidity range (manipulated in the experiments) was the main factor accounting for between-study variation in effect sizes. Also, capture rates of both visually and non-visually oriented predators decreased with an increase in turbidity. In addition, for visually oriented fish predators, the relative eye size did not influence the effect sizes. 4. Despite the paucity of studies for some groups of aquatic predators (mainly in tropical regions), we provide corroborative evidence that turbidity is a critical environmental factor controlling predator-prey interactions. This result is especially relevant considering that changes in turbidity is a human-induced pervasive environmental alteration resulted from, among other mechanisms, runoff after deforestation, eutrophication or oligotrophication in reservoir cascades, which imply changes in predator-prey interactions.</p>
Regional effect of visual clutter
<p class="western"><span><span><span><span>Stabilizing responses to disturbances are a critical part of the flight control system in flies. While strongly mediated by mechanoreception, much of the final steering response results from the wide field motion detection system associated with vision. The accuracy of the optomotor responses is affected when the characteristics of the visual input exceed the dynamic range of the motion detecting system. This has been demonstrated for stimulus parameters such as contrast, brightness, velocity, and spatial and temporal frequencies in gratings, but less is known about the effect of variables in more complex moving stimuli. By presenting laterally-moving dotfields of different densities we found that, in </span></span></span><span><i><span>Drosophila melanogaster</span></i></span><span><span><span>, the amplitude of the optomotor response is significantly affected by the level of visual clutter in the stimulus. Flies countersteer strongly within a relatively low and narrow range of element densities. But this effect is exclusive to the ventral region of the eye, and dorsal stimuli elicit an unaltered and stereotypical response throughout levels of visual clutter. This highlights local specialization of the eye and suggests the lower region may play a more critical role in translational flight-stabilization.</span></span></span></span></p>
Perceiving tempo in incongruent audiovisual presentation of human motion: Evidence for a visual driving effect
<p>The video set includes 81 audiovisual stimuli which served in the bisection experiment of the study "Perceiving tempo in incongruent audiovisual presentation of human motion: Evidence for a visual driving effect". The auditory sound tracks (bass drum) and visual stimuli (point-light displays of biological motions) each cover the tempo range from 60 to 180BPM, 15BPM per step. Coupling of the stimuli from both modalities results in 81 stimuli in total. </p>
Data from: Effects of arousal and movement on secondary somatosensory and visual thalamus
<p>Neocortical sensory areas have associated primary and secondary thalamic nuclei. While primary nuclei transmit sensory information to cortex, secondary nuclei remain poorly understood. We recorded juxtasomally from secondary somatosensory (POm) and visual (LP) nuclei of awake mice while tracking whisking and pupil size. POm activity correlated with whisking, but not precise whisker kinematics. This coarse movement modulation persisted after facial paralysis and thus was not due to sensory reafference. This phenomenon also continued during optogenetic silencing of somatosensory and motor cortex and after lesion of superior colliculus, ruling out a motor efference copy mechanism. Whisking and pupil dilation were strongly correlated, possibly reflecting arousal. Indeed LP, which is not part of the whisker system, tracked whisking equally well, further indicating that POm activity does not encode whisker movement <em>per se.</em> The semblance of movement-related activity is likely instead a global effect of arousal on both nuclei. We conclude that secondary thalamus monitors behavioral state, rather than movement, and may exist to alter cortical activity accordingly.</p>
