Data from: Acquisition of obligate mutualist symbionts during the larval stage is not beneficial for a coral host
Theory suggests that the direct transmission of endosymbionts from parents to offspring (vertical transmission) in animal hosts is advantageous and evolutionarily stable, yet many host species instead acquire their symbionts from the environment (horizontal acquisition). An outstanding question in marine biology is why some scleractinian corals do not provision their eggs and larvae with the endosymbiotic dinoflagellates that are necessary for a juvenile's ultimate survival. We tested whether the acquisition of photosynthetic endosymbionts (family Symbiodiniaceae) during the planktonic larval stage was advantageous, as is widely assumed, in the ecologically important and threatened Caribbean reef-building coral Orbicella faveolata. Following acquisition, similar changes occurred in larval energetic lipid use and gene expression regardless of whether their symbionts were photosynthesizing, suggesting the algae did not provide the energetic benefits characteristic of the mutualism in adults. Larvae that acquired photosymbionts isolated from conspecific adults on their natal reef exhibited a reduction in swimming, which may interfere with their ability to find suitable settlement substrate, and also a decrease in survival. Larvae exposed to two cultured algal species did not exhibit differences in survival, but decreased their swimming activity in response to one species. We conclude that acquiring photosymbionts during the larval stage confers no advantages and can in fact be disadvantageous to this coral host. The timing of symbiont acquisition appears to be a critical component of a host's life history strategy and overall reproductive fitness, and this timing itself appears to be under selective pressure.
Effect of tomato-fruit cultivar and ripening stage on Bactrocera tryoni (Froggatt) egg and larval survival
<p>In studies of frugivorous tephritids, determining when offspring (i.e. egg and three larval instars) mortality occurs within the fruit can greatly improve the mechanistic understanding of the fly/host interaction. Previous research has demonstrated that the Queensland fruit fly, <i>Bactrocera tryoni</i>, has differential offspring performance in two tomato cultivars Cherry and Roma, but when juvenile mortality was occurring was not determined. We examined <i>B. tryoni </i>egg and larval survival in three different ripening stages (immature-green (IG), colour-break (CB) and fully-ripe (FR)) of Cherry and Roma tomato cultivars through destructive fruit sampling at 72 and 120 hrs for eggs, and 48 (1<sup>st</sup> instar), 96 (2<sup>nd</sup> instar) and 120 hours (3<sup>rd</sup> instar) after fruit inoculation with neonates for larvae. Cultivar and ripening stage had no significant effect on egg survival, nor larval survival at 48 hrs: egg survival was high across all treatments, while 1<sup>st</sup> instar larval was low across all treatments. At 96 and 120 hrs, there were significant cultivar and ripening stage impacts on larval survival. In fully-ripe fruit, no further significant mortality happened after the first instar. However, in colour-break fruit, after the initial 1<sup>st</sup> instar mortality, high mortality also occurred in third instar larvae. In immature-green fruits nearly all mortality occurred during the first and second instars. The difference in timing of larval mortality with ripening stage provides indirect evidence of active fruit defense which is strongest in immature-green fruit, less in colour-break fruit and absent in fully-ripe fruit. Increased knowledge of fruit defenses against fruit flies is a starting point for developing fruit fly resistant crops.</p>
