2. The missing link:Exploring laterality and personality development in two fishes

Author

Abstract

This PhD thesis primarily investigated factors that may influence behavioural laterality and personality traits. I also examined the potential link between behavioural laterality and personality traits. Overall, I demonstrate how environmental factors, such as light and predation, can impact the development of laterality and personality using fish as animal models. Parents can also influence laterality of their offspring through genes and epigenetic effects. Additionally, I discovered a relationship between cognitive bias, laterality, and personality traits. I then explore how laterality may serve as a valuable indicator of welfare status and how environmental conditions can potentially influence laterality and associated behaviours. However, it's important to note that in none of my experiments did I find strong support for our hypothesis that behavioural laterality and personality traits are strongly correlated. The findings of the second chapter suggest that early light exposure can influence laterality in Western rainbowfish but is lost by maturity. The third chapter reveals that parental exposure to predators results in offspring with bolder personalities, greater lateralization, and smaller body size in three-spined sticklebacks. The fourth chapter suggests that laterality in three-spined sticklebacks is influenced by maternal effects; offspring with marine mothers exhibit population-level biases in laterality. In the fifth chapter, I found that bold, lateralized fish tend to display more optimistic cognitive biases, shedding light on the connection between internal states and behaviour, particularly in a welfare context. The sixth chapter is a review paper discussing the importance of understanding laterality in the context of fish welfare across various human-fish interaction contexts.

Abstract

Several factors affect the development of lateralization such as hormones and light exposure during early development. Laterality also often correlates with other behavioral traits. To examine whether there is a common mechanism underlying the development of laterality and other behaviors, we manipulated laterality by exposing embryos of the Western rainbowfish (Melatotaenia australis) to light or continuous darkness during early development and determined whether a shift in laterality was associated with a change in behavior in a novel environment test at two different ages. We found that exposing eggs to darkness led to offspring that displayed significantly less lateralized behavior in the mirror test two weeks after hatching than offspring from eggs exposed to light. Interestingly, the effects of rearing condition were lost by 3 months of age. These data suggest that exposure to light can influence laterality very early in development, but such bias can be overwritten by developmental processes post-hatch. Moreover, our manipulation of laterality apparently had no influence on exploration suggesting independent causal mechanisms. The experimental manipulation of light exposure during development could be a useful tool for enhancing individuals with a specific laterality and behavioral traits to aid future research into the causes and consequences of laterality.

Abstract

Caretta caretta is the most common sea turtle species in the Mediterranean Sea. The species is threatened by anthropomorphic activity that causes thousands of deaths and hundreds of strandings along the Mediterranean coast. Stranded turtles are often cared for in rehabilitation centres until they recover or die. The objective of this study was to characterize the gut microbiome of nine sea turtles stranded along the Sicilian coast of the Mediterranean Sea using high-throughput sequencing analysis targeting V3–V4 regions of the bacterial 16S rRNA gene. Stool samples were collected from eight specimens hosted in the recovery centre after a few days of hospitalization (under 7) and from one hosted for many weeks (78 days). To better explore the role of bacterial communities in loggerhead sea turtles, we compared our data with published fecal microbiomes from specimens stranded along the Tuscan and Ligurian coast. Our results highlight that, despite the different origin, size and health conditions of the animals, Firmicutes, Bacteroidetes and Proteobacteria constitute the main components of the microbiota. This study widens our knowledge on the gut microbiome of sea turtles and could be helpful for the set up of rehabilitation therapies of stranded animals after recovery in specialized centres.
