Consistency in the strength of laterality in male, but not female, guppies across different behavioural contexts (2020)
Journal Article
McLean, S., & Morrell, L. (2020). Consistency in the strength of laterality in male, but not female, guppies across different behavioural contexts. Biology Letters, 16(5), https://doi.org/10.1098/rsbl.2019.0870

Laterality, the division of brain functions into separate hemispheres, is widespread across animal taxa. Lateralised individuals exhibit cognitive advantages yet substantial variation in laterality exists, particularly between the sexes. Why variatio...

The influence of fieldwork design on student perceptions of skills development during field courses (2019)
Journal Article
Morrell, L. J., Peasland, E. L., Peasland, E., Henri, D. C., Morrell, L., & Scott, G. W. (in press). The influence of fieldwork design on student perceptions of skills development during field courses. International journal of science education, 1-20. https://doi.org/10.1080/09500693.2019.1679906

Employability is a key issue for students and Higher Education Institutions and a key component of employability is possessing the skills a role requires. In the environmental sciences, fieldwork has been shown to provide an opportunity for students...

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.

Foraging guppies can compensate for low-light conditions, but not via a sensory switch (2019)
Journal Article
Kimbell, H., Chapman, B., Dobbinson, K., & Morrell, L. (2019). Foraging guppies can compensate for low-light conditions, but not via a sensory switch. Behavioral Ecology and Sociobiology, 73, https://doi.org/10.1007/s00265-019-2640-9

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...

Local interactions and global properties of wild, free-ranging stickleback shoals (2017)
Journal Article
Ward, A. J. W., Schaerf, T. M., Herbert-Read, J. E., Morrell, L., Sumpter, D. J. T., & Webster, M. M. (2017). Local interactions and global properties of wild, free-ranging stickleback shoals. Royal Society Open Science, 4(7), 170043. doi:10.1098/rsos.170043

Collective motion describes the global properties of moving groups of animals and the self-organized, coordinated patterns of individual behaviour that produce them. We examined the group-level patterns and local interactions between individuals in w... Read More about Local interactions and global properties of wild, free-ranging stickleback shoals.

Student perceptions of their autonomy at University (2017)
Journal Article
Henri, D. C., Morrell, L. J., & Scott, G. W. (2018). Student perceptions of their autonomy at University. Higher Education, 75(3), 507-516. https://doi.org/10.1007/s10734-017-0152-y

© 2017, The Author(s). Learner autonomy is a primary learning outcome of Higher Education in many countries. However, empirical evaluation of how student autonomy progresses during undergraduate degrees is limited. We surveyed a total of 636 students...

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.

Colour preferences of UK garden birds at supplementary seed feeders (2017)
Journal Article
Rothery, L., Scott, G. W., & Morrell, L. J. (2017). Colour preferences of UK garden birds at supplementary seed feeders. PloS one, 12(2), https://doi.org/10.1371/journal.pone.0172422

Supplementary feeding of garden birds generally has benefits for both bird populations and human wellbeing. Birds have excellent colour vision, and show preferences for food items of particular colours, but research into colour preferences associated...
