Abbreviations: * = six days isolated silverfish; ** = nine days isolated silverfish A control experiment was performed with silverfish to determine whether the isolation treatment itself had an effect on their social acceptance, rather than changes in their CHC signature (e.g., due to physical suffering or adoption of additional compounds that originate from the experimental setup).
Francis Omaswa, who led Uganda's successful effort to control an Ebola epidemic in 2000, said last week, "Controlling the epidemic is about early detection, isolation, treatment of new infections, contact tracing, and safe handling of body fluids and the remains of those who die".
In addition, limited or no information was collected in the interview about a number of factors that may be important for nonadherence, including social support, isolation, treatment efficacy, and self-efficacy [32], [33].
Eggs that accessed the sperm of multiple males simultaneously achieved, on average, ∼17% higher rates of fertilisation than eggs that accessed sperm from the same males but in isolation (Treatment: F1,9 = 11.03, P = 0.009; Block: F9,17 = 11.93, P<0.001; Treatment×Block: F9,17 = 2.81, P = 0.032, Figure 2).
When we examined larval survival, there was a significant interaction between Block and the treatment and so the main effect of treatment could not be examined in isolation (Treatment: F2,4 = 3.78, P = 0.120; Block: F2,8 = 0.64, P = 0.55 Treatment×Block: F4,8 = 3.89, P = 0.048).
Many workers come from the same communities they work in, part of an effort to bring isolation treatment and basic care closer to the village level.
The number of detected host compounds on silverfish decreased after isolation treatments (no isolation: Ncompounds = 28, Nsilverfish = 63; 6 days isolation: Ncompounds = 22, Nsilverfish = 12; 9 days isolation: Ncompounds = 23, Nsilverfish = 58).
In agreement with a behavioural adoption, the mimetic CHCs on silverfish decreased in isolation treatments quantitatively (total concentration) and qualitatively (relative abundance and presence or absence).
However, in our experiments an acquisition of additional compounds during isolation treatments that could have been responsible for the observed aggression seems unlikely for several reasons.
To test whether the chemical similarity of silverfish to their host colony was influenced by isolation treatments, Bray-Curtis similarities to the average worker CHC profile of the respective host colony were used as a univariate response variable, and a PERMANOVA with a 2-factor nested design (colonies (random), days of isolation (fixed), nested in colony) was applied.
For vertical vibration isolation, the treatment of the Euler spring isolator is based on the post-buckling dynamic characteristics of the column elastica and axial stiffness.
