Extended Data Table 4 | Individual- and population-level lateralization of coral reef fishes
Individual- and population-level lateralization was tested for four species of coral reef fishes (P. amboinensis, C. atripectoralis, D. aruanus and P. moluccensis) in a detour test (LIRS 2014) under
control (around 400 μatm CO 2 ) and high CO 2 (about 1,000 μatm) conditions. The sample size (n) and mean number of right turns (X) out of a total of 10 turns is indicated for each species and
treatment group (sample sizes represent biologically independent animals). χ^2 statistics (ind χ^2 ) and P values (ind P) are presented for tests of individual-level lateralization. z values (pop z)
and P values (pop P) are presented for tests of population-level lateralization. P < 0.05 indicates lateralization. ‘retest’ indicates a subset of individuals that underwent a second trial in an
effort to validate the findings from their first trial. Statistical significance is indicated in bold (α = 0.05).
