| Abstract |
The drastic shift from pelagic larvae to benthic adult form that occurs during marine invertebrate metamorphosis is often induced by intimate interactions between settling larvae and their benthic environment. Larval experience prior to and during metamorphosis can significantly affect adult fitness, but it is presently unknown whether the exact nature of the inductive cue is an experience that matters, or by what mechanism such carry-over effects are mediated. Here we test for carry-over effects of the specific nature of inductive cues on gene expression in metamorphosing postlarvae of the tropical abalone, Haliotis asinina. Postlarvae induced by three different species of coralline algae all successfully undergo metamorphosis, yet the expression profiles of 11 of 17 metamorphosis-related genes differ according to which species of algae the larvae settled upon. Significantly, several genes continue to be differentially expressed for at least 40 h after removal of the algae from the postlarvae, clearly demonstrating a carry-over effect of inductive cue on gene expression. We observe a carryover effect in several genes with varying functions and spatial expression patterns, indicating that each algal species impacts global gene expression in a unique manner. These data unexpectedly reveal that transcriptional modulation of metamorphosis-related genes is contingent upon the precise composition of the benthic microenvironment experienced directly at induction of settlement, and highlight transcription as a mechanism that can mediate between larval and postlarval experiences. For new recruits into an abalone population, metamorphosis clearly does not represent a new transcriptional beginning. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 November 2009.
All research outputs
#16,727,629
of 24,602,766 outputs
Outputs from Molecular Ecology
#5,612
of 6,592 outputs
Outputs of similar age
#81,992
of 97,518 outputs
Outputs of similar age from Molecular Ecology
#22
of 24 outputs
Altmetric has tracked 24,602,766 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,592 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 11.5. This one is in the 9th percentile – i.e., 9% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 97,518 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
