All sham animals treated with placebo survived (mortality 0%, Fig. 4).
Older honey bee larvae are less likely rejected [31], and a higher percentage survived (mortality was 24%) when treatments were initiated during the 4th instar.
In the streptozotocin-treated group, 40 animals survived (mortality rate: 42%, n = 20 males and 20 females).
In the citrate buffer-treated group, 38 animals survived (mortality rate: 0%, n = 21 male and 17 female).
In a convincing study, Martin et al. [ 29] reported that although patients with admission hypothermia at <32°C have high mortality, some do survive and mortality rates remain constant at temperatures between 27°C and 32°C.
Most of those who are stricken survive, but mortality is higher among the elderly.
If older children are more likely to survive, then mortality may decline more than incidence.
Embryos may be most vulnerable to warming while larvae that survive early mortality bottlenecks may be more affected by acidification [13], [15], [18], [34], [47].
Hence, the larger initial size and the status of multi-polyp at settlement may confer these inborn colonies better capacities to compete for space and survive partial mortality.
Since our laboratory colonies tended to survive this mortality window despite endophyte loads, however, this hypothesis assumes that the cost of endophytes in ant forage material interacts with other environmental or biotic factors to cause less productivity or greater mortality.
This group (the nonprolonged group) consisted of two types of patients: the first is patients with an illness too severe to survive (early mortality patients); the other is patients who have a real nonprolonged ICU stay.
