Dynamic colour change in zebrafish () across multiple contexts.

Many animals are capable of rapid dynamic colour change, which is particularly well represented in fishes. The proximate mechanisms of dynamic colour change in fishes are well understood; however, less attention has been given to understanding its ecological relevance. In this study, we investigate dynamic colour change in zebrafish () across multiple contexts, using a protocol to image the colouration of live fish without anaesthesia under standardized conditions.

Factors associated with quality of life in long-COVID syndrome.

Approximately 10% of patients experience persistent symptoms following COVID-19, known as long-COVID syndrome. This cross-sectional study explored factors of quality of life (QoL) in 53 long-COVID patients. QoL was measured using the World Health Organization-Five Well-Being Index, fatigue with the Fatigue Visual Analogue Scale, and psychological health with the Depression-Anxiety-Stress-21 questionnaire.

Predator Personality Variation, Not the Multiple Stressors of Temperature and Light, Determines Feeding Motivation in an Ambush Piscivore .

Environmental conditions in freshwater ecosystems are increasingly determined by human activity. Increased temperature and light intensity are among the anthropogenic stressors dramatically altering these ecosystems, for example, through deforestation that reduces canopy cover of riparian vegetation. Simultaneous exposure to multiple stressors complicates predictions of responses to environmental stressors due to potential interactions, yet the interaction between temperature and light intensity on feeding motivation remains poorly understood.
