Rapid adaptation to controlling new microbial epibionts in the invaded range promotes invasiveness of an exotic seaweed

Summary Rapid adaptation to novel biotic interactions and abiotic factors in introduced ranges can be critical to invasion success of both exotic terrestrial and aquatic plants. Seaweeds are extremely successful biological invaders in marine environments. Along with herbivores, foulers − ubiquitous enemies in the marine environment − have the potential to determine the success or failure of invasive seaweeds. However, research on the topic of rapid adaptation of seaweeds to biotic challenges is still in its nascent stages and rapid adaptation of seaweeds to fouling is unexplored. We tested whether the impressive invasion success of the red macroalga Gracilaria vermiculophylla may be enhanced by the rapid adaptation of chemical control (defence) of new bacterial epibionts in the invaded range. The native and invasive G. vermiculophylla populations investigated were equally well defended against currently co‐occurring bacterial epibionts isolated from their respective ranges. In contrast, the native populations were weakly defended against bacterial epibionts from the invaded range, whereas the invasive populations were weakly defended against bacterial epibionts from their native range. Apparently during the invasion process, invasive populations have adapted their control capacity to cope with the new epibionts but have lost the capacity to fend off old epibionts. Synthesis. These results provide the first evidence that a change in habitat and, thus, confrontation by new enemies, may trigger rapid defence adaptation of seaweeds, which could be necessary for invasiveness. Such adaptation dynamics as found in the current study could be also applicable to other types of host plant – enemy interaction e.g. plant root – microbe interactions, freshwater plant – fouler interactions in general and for cases of shifting plant – enemy interactions in course of climate change.

“…Toxic prostaglandins (PGE 2 ) are found in the Asian Gracilaria vermiculophylla , which invaded North American and European shores in recent decades (Hammann et al 2016). Wounding of G. vermiculophylla increases synthesis of PGE 2 from arachidonic acid within minutes (Noguchi et al 1994; Nylund et al 2011).…”

“…Wounding of G. vermiculophylla increases synthesis of PGE 2 from arachidonic acid within minutes (Noguchi et al 1994; Nylund et al 2011). Hammann et al (2016) showed that this effect was enhanced in invasive populations, finding that this appears to be a defense against naïve herbivores in the non-native habitat. Their study characterized many additional metabolites present in G. vermiculophylla .…”

Algae as nutritional and functional food sources: revisiting our understanding

et al. 2016

View full text Add to dashboard Cite

Global demand for macroalgal and microalgal foods is growing, and algae are increasingly being consumed for functional benefits beyond the traditional considerations of nutrition and health. There is substantial evidence for the health benefits of algal-derived food products, but there remain considerable challenges in quantifying these benefits, as well as possible adverse effects. First, there is a limited understanding of nutritional composition across algal species, geographical regions, and seasons, all of which can substantially affect their dietary value. The second issue is quantifying which fractions of algal foods are bioavailable to humans, and which factors influence how food constituents are released, ranging from food preparation through genetic differentiation in the gut microbiome. Third is understanding how algal nutritional and functional constituents interact in human metabolism. Superimposed considerations are the effects of harvesting, storage, and food processing techniques that can dramatically influence the potential nutritive value of algal-derived foods. We highlight this rapidly advancing area of algal science with a particular focus on the key research required to assess better the health benefits of an alga or algal product. There are rich opportunities for phycologists in this emerging field, requiring exciting new experimental and collaborative approaches.Electronic supplementary materialThe online version of this article (doi:10.1007/s10811-016-0974-5) contains supplementary material, which is available to authorized users.
