“…This dramatic transcriptional shift in colonial cells supports a high resource cost associated with producing colonies (Wang et al. ). Specifically, our results indicate that resources are being diverted from protein translation and transport and cell division in order to produce or maintain the colonial matrix.…”

Phaeocystis globosa forms dense, monospecific blooms in temperate, northern waters. Blooms are usually dominated by the colonial morphotype—nonflagellated cells embedded in a secreted mucilaginous mass. Colonial Phaeocystis blooms significantly affect food‐web structure and function and negatively impact fisheries and aquaculture, but factors regulating colony formation remain enigmatic. Destructive P. globosa blooms have been reported in tropical and subtropical regions more recently and warm‐water blooms could become more common with continued climate change and coastal eutrophication. We therefore assessed genetic pathways associated with colony formation by investigating differential gene expression between colonial and solitary cells of a warm‐water P. globosa strain. Our results illustrate a transcriptional shift in colonial cells with most of the differentially expressed genes downregulated, supporting a reallocation of resources associated with forming and maintaining colonies. Dimethylsulfide and acrylate production and pathogen interaction pathways were upregulated in colonial cells, suggesting a defensive role for producing colonies. We identify several protein kinase signaling pathways that may influence the transition between morphotypes, providing targets for future research into factors affecting colony formation. This study provides novel insights into genetic mechanisms involved in Phaeocystis colony formation and provides new evidence supporting a defensive role for Phaeocystis colonies.

“…Previous studies testing for a cost of multicellular group formation have tended to obtain positive results (Lurling and Van Donk 2000;O'donnell et al 2012;Wang et al 2014;Wang et al 2015;Zhu et al 2015;Zhu et al 2016). Potential costs of group forma-tion include resource competition, a cost of producing extracellular adhesive molecules, and higher sinking rates (Reynolds 1984;Lancelot and Mathot 1985;Kirk 1994;Trainor 1998;Ploug et al 1999;Lürling 1999;Tollrian and Dodson 1999).…”

The first step in the evolution of complex multicellular organisms involves single cells forming a cooperative group. Consequently, to understand multicellularity, we need to understand the costs and benefits associated with multicellular group formation. We found that in the facultatively multicellular algae Chlorella sorokiniana: (1) the presence of the flagellate Ochromonas danica or the crustacean Daphnia magna leads to the formation of multicellular groups; (2) the formation of multicellular groups reduces predation by O. danica, but not by the larger predator D. magna; (3) under conditions of relatively low light intensity, where competition for light is greater, multicellular groups grow slower than single cells; (4) in the absence of live predators, the proportion of cells in multicellular groups decreases at a rate that does not vary with light intensity. These results can explain why, in cases such as this algae species, multicellular group formation is facultative, in response to the presence of predators.

“…Loss of individuals, although not terminal, may reduce overall colony fitness through costs associated with induced defences or loss of reproductive structures (Harvell ; Rotjan & Lewis ; Wang et al . ) but may be beneficial in other ways by allowing removal of competitors or helping to create recruitment opportunities where space is limited (e.g. Mumby ).…”

Uncovering the holes and cracks: from anecdote to testable hypotheses in predation studies

Biological interactions between organisms have long been believed to be very important in structuring communities and, when scaled up over geological time, in the evolution of organisms. Investigations of palaeontological evidence for predator–prey interactions have been popular pursuits, and a number of attractive hypotheses have been proposed which link increased predation pressure with a wide range of morphological and ecological changes which are apparent over the course of the Phanerozoic. In particular studies of fossil drill holes and repair scars in shelly prey have been common targets for research. However, the nature of some of our data has been rather anecdotal and restricted in range. Perhaps we should be more concerned that we are not picking up the true range of natural variability. This paper aims to highlight the sources of variability in our data and, going forward, to urge the collection of quantitative data from many more samples and (palaeo)environmental settings in order that we might properly be able to separate the intrinsic natural variability in our data from robust temporal or spatial trends.
