At placement temperatures of 20°C or below, few or no larvae moved toward the zone of higher temperature.
A 'first choice' response was noted when larvae moved inside one arm.
During this work, we noted that lam larvae pupariated lower on the sides of the vials than controls did (Fig. 4A), suggesting that lam larvae moved less.
The heavier larvae moved earlier than lighter larvae to young leaves which typically have higher levels of protein and water contents [ 27, 48, 49].
Stonefly larvae kept moving during most of the observation periods under both treatments, whereas mayfly larvae moved 27% of the time without trout (F1,18=33.1, p<0.001) and 19% of the time when trout were present (F1,18=46.5, p<0.001).
The tracks of parkin mutant larvae crawling across an agar plate are shorter for animals migrating for a set interval of time (2 min) than wild-type as the parkin larvae move more slowly (Fig. 1A).
After hatching, the young larvae move toward the lower part of the internode while they feed on the sheath.
Nor is the selective abortion of parasitized carpels an option because developing larvae move freely from one carpel to another.
In contrast, imaging gfp positive eater mutant plasmatocytes showed that the majority of gfp+ hemocytes do not remain stationary with respect to the cuticle as the larva moved, indicating that the majority of eater deficient hemocytes lacked sessility (supplementary material Fig. S1 and Movie 2).
To test visual system function in kif5aa mutant larvae, we employed the optokinetic response (OKR) to a moving grating as a sensitive and quantifiable indicator of visual functions in zebrafish (Brockerhoff et al., 1995).
