Computerized stimuli for studying oddity effects (2019)
Journal Article
Morrell, L., Dobbinson, K., & Skarratt, P. (in press). Computerized stimuli for studying oddity effects. Behavioral ecology, https://doi.org/10.1093/beheco/arz174

Visually hunting predators must overcome the challenges that prey groups present. One such challenge is the confusion effect where an overburdened visual system means predators are unable to successfully target prey. A strategy to overcome confusion...

Iterated assessment and feedback improves student outcomes (2019)
Journal Article
Morrell, L. J. (in press). Iterated assessment and feedback improves student outcomes. Studies in higher education, https://doi.org/10.1080/03075079.2019.1643301

Feedback is critically important to student learning, but reduced frequency of assignments combined with isolated or stand-alone tasks reduces the opportunity for students to engage with feedback and use it effectively to enhance their learning. Here... Read More about Iterated assessment and feedback improves student outcomes.

Animals can adapt to changes in their environment through behavioural or developmental plasticity, but studies of these responses tend to focus on either short-term exposure of adults to the changed conditions, or long-term exposure of juveniles. Juv... Read More about Foraging guppies can compensate for low-light conditions, but not via a sensory switch.

Group size and individual ‘personality’ influence emergence times in hermit crabs (2018)
Journal Article
Broadhurst, H. E., & Morrell, L. J. (2019). Group size and individual ‘personality’ influence emergence times in hermit crabs. Bioscience Horizons, 11, doi:10.1093/biohorizons/hzy011

Many animals benefit from aggregating due to the anti-predator effects associated with living in groups. Hermit crabs are known to form groups, or ‘clusters’, which may occur at sites of high shell availability. Clustering may also have anti-predator...

Disturbed flow in an aquatic environment may create a sensory refuge for aggregated prey (2017)
Journal Article
Johannesen, A., Dunn, A. M., & Morrell, L. J. (2017). Disturbed flow in an aquatic environment may create a sensory refuge for aggregated prey. PeerJ, 5, https://doi.org/10.7717/peerj.3121

Predators use olfactory cues moved within water and air to locate prey. Because prey aggregations may produce more cue and be easier to detect, predation could limit aggregation size. However, disturbance in the flow may diminish the reliability of o... Read More about Disturbed flow in an aquatic environment may create a sensory refuge for aggregated prey.

The ability to change coloration allows animals to modify their patterning to suit a specific function. Many freshwater fishes, for example, can appear cryptic by altering the dispersion of melanin pigment in the skin to match the visual background....
