“…In such GLMs the individual traits (length, weight, or oxygen consumption), foraging time or time spent associating with the stimuli shoals were the dependent variable/s, and the species or treatment (shoal composition) were the fixed factor. All model comparisons were performed using ANOVA in ‘car’ package (Fox and Weisberg, 2019) and post hoc paired tests (Tukey’s post hoc HSD Test) were carried out for comparing the effects of factors that were significant. Chi square tests were performed to check whether the average food consumption by zebrafish individuals in conspecific shoals is comparable to the average food consumption by zebrafish individuals in mixed-species shoals.…”

Mixed-species groups commonly occur across a wide range of faunal communities and are known to provide several benefits to members. While zebrafish have often been observed to form mixed-species shoals with coexisting species, the factors determining their occurrence are not yet understood. Using laboratory-based experiments, we decipher the main ecological drivers of mixed-species shoaling in these tropical fish communities. Shoals comprising zebrafish (Danio rerio), flying barbs (Esomus danricus), and whitespots (Aplocheilus panchax) were collected from a stagnant canal at Haringhata (West Bengal, India). Experiments to assess foraging efficiency were conducted where single or mixed-species shoals (comprising 5 individuals) were given low or high amounts of food. Shoal choice experiments were also conducted to assess the preferences of test subjects (zebrafish individuals) for forming associations based on shoal composition and familiarity. Results from experiments on feeding efficiency revealed that foraging time varied substantially among the shoal types (i.e., single or mixed-species), and was dependent on the quantity of food available, but not linked to the body size of species composing the shoal. The choice experiments to examine preference for associations revealed that under predator risk, zebrafish associate more with mixed shoals, and showed comparable associations to shoals differing in the abundance of conspecifics. Furthermore, we found that zebrafish preferred to associate with familiar conspecific over unfamiliar mixed and unfamiliar conspecific shoals. Therefore, equitable food consumption in mixed shoals, greater association with mixed shoals in presence of predators, and familiarity were found to be important drivers for choosing mixed-species shoaling by zebrafish.

Aims: To measure the impact of Canada's recreational cannabis legalization (RCL) in October 2018 and the subsequent impact of the coronavirus disease 2019 (COVID-19) lockdowns from March 2020 on rates of emergency department (ED) visits and hospitalizations for traffic injury. Design: An interrupted time series analysis of rates of ED visits and hospitalizations in Canada recorded in population-based databases from January/April 2010 to March 2021.

Mixed-species groups occur across a wide range of faunal communities and provide several benefits to members. While zebrafish have often been observed to form mixed-species shoals with coexisting species, the factors determining their occurrence are not yet fully understood. Shoals comprising zebrafish (Danio rerio), flying barbs (Esomus danricus), and whitespots (Aplocheilus panchax) were collected from a stagnant canal at Haringhata (West Bengal, India), and using laboratory-based experiments, we deciphered likely drivers of mixed-species shoaling among zebrafish. Experiments assessing foraging efficiency revealed that the amount of food consumed by zebrafish individuals in mixed shoals was comparable to the amount consumed by these individuals in conspecific shoals. Within mixed-species shoals, zebrafish individuals, despite being smaller than the other species, consumed a comparable amount of food as the other species. Shoal choice experiments revealed that under predator risk, zebrafish associate more with mixed shoals and showed comparable associations to shoals differing in the abundance of conspecifics. Furthermore, zebrafish preferred associating with familiar conspecifics over unfamiliar mixed and unfamiliar conspecific shoals. Therefore, equitable food consumption in mixed shoals, greater association with mixed shoals in the presence of predators, and familiarity were important in driving zebrafish towards mixed-species shoaling.
