Area step step step 1: forager size changes along the foraging year

With the earliest area, for every mix of predictors are checked 3 times, making use of the about three human body specifications just like the reaction parameters. We modelled the results of “months” and you can “locatweons” (we.elizabeth. apiary ID) to your proportions dimension and on the coefficient out-of type (CoV). We tested the effect out-of months because a factor and possess due to the fact an effective covariate during the separate models. Significantly more truthfully, whenever assessment months once the something, i checked-out having a distinction in proportions measurements anywhere between some of the new weeks, whereas whenever evaluation days because the good covariate, we checked-out for a broad pattern (increase otherwise disappear) over the days. At the same time, we examined the consequences off nest proportions as well as if an effective nest swarmed when you look at the independent models because this advice is actually offered simply to possess a great subset of territories. I felt territories for swarmed just after swarming taken place and you may as well as when they was indeed split to get rid of absolute swarming (did on the presence off swarm cells). To test whether or not swarming inspired muscles proportions proportions, we opposed your body measurements from the week before swarming in order to dimensions removed the three adopting the weeks.

Therefore, the fresh matchmaking within areas of the body was equivalent in every around three places

On the second area, i used LMEs to check on whether or not the waggle work at duration of bees away from a nest try linked to the average head proportions out-of bees off that nest. During the last region, LMEs were did to check on in the event that waggle manage period conveyed of the a performer is coordinated into lead thickness of the same performer.


The three body measurements were highly correlated (LME; head-wing ? 2 1 = , P < 0.0001; head-leg ? 2 1 = , P < 0.0001; wing-leg ? 2 1 = , P < 0.0001). There was no interaction with location (LME; head-wing ? 2 2 = 2.1167, P = 0.347; head-leg ? 2 2 = 1.5043, P = 0.471342; wing-leg ? 2 2 = 1.6048, P = 0.4483). Our results also indicated that the relationship between the leg width and the head width was allometric (slope = 2.2, CI 2.09–2.3), as well as the relationship between the leg width and the forewing length (slope = 2.08, CI 1.99–2.18). The relationship between the head width and forewing length was isometric (slope = 1.05, CI 1–1.09).

Using month as a factor, a significant interaction was found between the months and the locations for each body part (head ? 2 fourteen = 55.5, P = <0.0001; wing ? 2 14 = 27.5, P = 0.0164; leg ? 2 14 = , P < 0.0001). Thus, the change in size during the season differed between locations. More precisely, the two apiaries in Lausanne show highly significant differences of bee size between the months (see Table I). This is not the case for the apiary in Liebefeld (except for the leg measurements, Table I). To explore the temporal effects further, we used month as covariate to test if there was a tendency of bees to increase in size during the study period. We found that the three body measurements significantly increased over the months (LME; head ? 2 1 = , P < 0.0001; wing ? 2 1 = , P = 0.0007; leg ? 2 1 = 7.1524, P = 0.007) (Figure 2). Subsequent analyses, exploring general patterns over the months, found no interaction between the month and the location (head ? 2 2 = 1.8578, P = 0.395; wing ? 2 2 = 4.9916, P = 0.082; leg ? 2 2 = 1.012, P = 0.603).

Head width (a), forewing duration (b) and you may hind foot width (c) split up because of the apiaries by days. Field plots of land into kept portray Liebefeld apiary (Liebefeld), in-between show the latest terrace apiary within the Lausanne (Terrace) as well as on just the right depict new roof apiary from inside the Lausanne (Roof). The fresh new packets suggest the info involving the twenty-five and you may 75 % quartiles including the median (black colored range); this new whiskers represent minimal and you may restriction philosophy, outliers omitted (illustrated from the open circles).
