The star represents the geographic coordinates of the experiment location.
Fig 2.
Experimental design for field (a) and lab (b) experiments.
Arrangement of moisture levels in both experiments was randomized.
Table 1.
Numbers of eggs oviposited on cotton substrate (values summed per moisture level) after 48 hours in field and lab experiments.
Fig 3.
Cricket oviposition responses to substrate moisture level.
(a) represents oviposition probability, a binary response variable with a value of either 0 (if oviposition did not occur in any replicate containers for that moisture level) or 1 (if oviposition occurred at least one of the container replicates in that level). Circles represent the field experiment, while triangles represent the lab experiment. The size of circles and triangles represents the number of observations (= the number of replicates in which the binary response occurred) for the same moisture level. Curves represent the minimal adequate model of the adjusted logistic regression (solid line for field experiment, dashed line for lab experiment; n = 30 for each experiment). (b) Numbers of eggs deposited per container by moisture level in field (circles) and lab (filled triangles) experiments. Curves represent the minimal adequate model of the adjusted regression (GLMM with negative binomial distribution) for field (solid line) and lab (dashed line) experiments (n = 30 for each experiment). The equations represent the estimated parameters for each model.
