“…Vermetids cannot colonize live coral tissue (Phillips et al 2014); instead, they rely on disturbances to open up free space. We suggest that these cryptic coral phenotypes are key to understanding coral‐vermetid dynamics in this system.…”

Phenotypic variation can lead to variation in the strength and outcome of species interactions. Variation in phenotypic traits can arise due to plastic responses to environmental stimuli, underlying genetic variation, or both, and may reflect differences in the focal organism or aspects of the extended phenotype (e.g., associated microbes). We used a reciprocal transplant experiment of Porites corals to evaluate the role of plasticity vs. heritable diversity on phenotypic traits and performance of corals that varied in their prior exposure to vermetid gastropods, an organism known to reduce coral growth and survival. We measured a suite of phenotypic traits associated with coral performance, many of which showed a plastic response to vermetid exposure. Vermetids decreased calcification of corals, increased microbial diversity, and shifted microbial composition. Most traits also showed a signature of previous exposure environment that persisted even when exposure was reversed: i.e., under the same conditions, corals naïve to vermetids had slower calcification rates, thicker tissues, higher Symbiodiniaceae densities, and different microbiomes than corals previously exposed to vermetids. We suggest the phenotypic differences are heritable, as reefs with and without vermetids were comprised of two different mitotypes, that revealed high, consistent genetic variation. Vermetids were only found on the fast‐growing coral mitotype that was characterized by thin tissue, and that likely had a history of disturbance. As extended phenotypes can have community impacts, we suggest vermetid, in addition to microbes, are part of the extended community phenotype of these corals. Coral genotypes can establish different reef trajectories, with thin‐tissue types more prone to disturbance and subsequent colonization by other species, like vermetids, which can further facilitate the degradation of coral reefs. The effects of the extended phenotype of species likely influence heterogeneity across landscapes as well as temporal differences in community composition.

“…et al 2014 for recent taxonomic revision), reduces the growth and survival of several species of corals and may have the ability to dramatically alter coral growth forms (Colgan 1985;Zvuloni et al 2008;Shima et al 2010). C. maximum produces pelagic larvae (Phillips and Shima 2010) that settle and permanently attach to bare substrate (Phillips et al 2014). Settled individuals grow by adding to uncoiled tubular shells and often become encased in a matrix of live and dead coral.…”

colony morphology. Given that structural complexity of coral colonies is an important determinant of "habitat quality" for many other species (fishes and invertebrates), these results suggest that the vermetid gastropod, C. maximum (with a widespread distribution and reported increases in density in some portions of its range), may have important indirect effects on many coral-associated organisms.

“…Our previous work (Phillips et al 2014) suggests that living coral tissue inhibits vermetid recruitment (live corals can kill and consume vermetid larvae), so high coral cover may provide initial 'resistance' to vermetid establishment, preventing population outbreaks from starting. Vermetids also increase coral mortality (e.g.…”

with biomass was steeper for reefs where vermetid densities had been experimentally reduced. Survival was also greater on living coral Porites lobata (where coral growth covered longitudinal extensions of vermetid shells) relative to dead coral substrate (where vermetid shells extensions remained exposed). These data suggest little scope for regulation of vermetid population growth via direct density dependence in demographic rates. However, given that vermetids can kill corals, and vermetid survival probabilities appear to depend upon coral cover, it is predicted that vermetids may experience cyclical dynamics that are coupled to the dynamics of living coral.
