NGS-57078R-19), the Teasley Endowment to the Georgia Institute of Technology, and the Anna and Harry Teasley Gift Fund.</p> Methods and Sampling: <p>To test the impact of macroalgal species richness on coral performance, we manipulated macroalgal assemblages on the upper surface of 25 cm x 21 cm cement plots that each contained six&nbsp;<em>Pocillopora verrucosa</em>&nbsp;coral outplants (6 corals per plot, 72 plots, 432 corals total). Each plot was affixed to the substrate and elevated&nbsp;~30 cm&nbsp;to prevent scour by sand and rubble. The upper surface of each plot contained a 4 x 3 grid space, with upturned soda bottle caps embedded within each space. To create a standardized coral population, 6–8 cm length branches of&nbsp;<em>P. verrucosa&nbsp;</em>were fragmented from colonies&nbsp;<em>in situ&nbsp;</em>and individually epoxied (Z-Spar A-788 Splash Zone Epoxy) into the cut-off necks of inverted plastic bottles&nbsp;(following methods of Clements and Hay 2015). Prior to outplanting, all corals and their epoxy/bottle-top base were wet-weighed in the field using an electronic scale (OHAUS Scout Pro) enclosed within a plastic container mounted to a tripod holding it above the water surface. Before weighing, each coral was gently shaken 30 times to remove excess water, and then weighed, immediately placed back into the water, and attached to their designated plot. Six corals that each originated from different&nbsp;<em>P. verrucosa&nbsp;</em>colonies were attached to plots by screwing the corals into bottle caps embedded within every other grid space within each plot.</p>
<p>We varied the macroalgal community on the upper surface of each plot by outplanting monocultures holding similar masses of: (1)&nbsp;<em>Sargassum pacificum</em>, (2)&nbsp;<em>Turbinaria ornata</em>, or (3)&nbsp;<em>Amansia rhodantha</em>, as well as (4) polycultures containing all three species (12 plots per treatment; Figure 1 of Clements et al., 2024). There were also two additional treatments: (5) plots with plastic algal mimics to control for effects of shading or abrasion unrelated to the biotic properties of live seaweeds and 6) control plots where corals, but not living algae or physical mimics, were present (<em>n</em>&nbsp;= 12 plots per treatment).&nbsp;</p>
<p>To create six standardized units of macroalgae or algal mimics within every other space of the 4 x 3 grid of each plot, cable ties were first individually epoxied into the cut-off necks of inverted plastic bottles that were screwed into bottle caps embedded within the plots. An additional cable tie was then used to attach either&nbsp;<em>Sargassum</em>&nbsp;(two ~6-8 cm thalli),&nbsp;<em>Turbinaria</em>&nbsp;(two ~6-8 cm thalli),&nbsp;<em>Amansia</em>&nbsp;(two ~6-8 cm thalli), or algal mimics (two ~6 cm plastic aquarium plants) to the cable tie embedded in each soda bottle neck. Standardized units used in control plots only had a cable tie attached to the embedded cable tie. In polycultures, units of&nbsp;<em>Sargassum</em>,&nbsp;<em>Turbinaria</em>, and&nbsp;<em>Amansia</em>&nbsp;(2 units/species/plot) were distributed to ensure that conspecifics were not located adjacent to one another within the grid space of the plot and so that the mass of each species was approximately the same (Figure 1 of Clements et al., 2024). Any macroalgae or algal mimics displaced from their cable tie (e.g., because of wave action or herbivory) were replaced every 1-2 days, and all mimics were replaced weekly to minimize the influence of fouling organisms (e.g., diatoms, cyanobacteria) that might produce chemical or biological interactions confounding the physical effects these biologically inert "controls" are meant to produce. The different treatments were interspersed randomly to prevent confounding spatial effects with treatment effects.</p>
<p>The percentage growth and tissue mortality of individual corals in each plot were assessed at 9 weeks (experiment initiated on 30 May with treatment effects assessed on 7 August 2021). Each coral was visually examined from all sides and the percentage tissue mortality was estimated and assigned in 10% classes (0, 10, 20%, etc., up to 100%). Twenty-four to 48 hours before the second weighing session, each coral’s epoxy/bottle-top base was brushed clean of fouling organisms. To assess growth, corals were detached from the substratum, reweighed in the field as previously described to determine the percentage change in mass, and immediately placed back into the water and reattached to their respective bottle cap.</p>

Positive Effects of Coral Biodiversity on Coral Performance: Patterns, Processes, and Dynamics

Positive Effects of Coral Biodiversity on Coral Performance: Patterns, Processes, and Dynamics
<p><em>NSF Award Abstract:</em><strong> </strong><br />
Coral reefs are extremely diverse, supply critical ecosystem services, and are collapsing at an alarming rate, with 80% coral loss in the Caribbean and >50% in the Pacific in recent decades. Previous studies emphasized negative interactions (competition, predation) as structuring reef systems, but positive interactions in such species-rich systems could be of equal importance in maintaining ecosystem function. If foundation species like corals depend on positive interactions, then their fitness may decline with the loss of surrounding species, creating a biodiversity meltdown where loss of one coral causes losses of others. This project conducts manipulative field experiments to understand the role of coral biodiversity in facilitating coral growth, survival, resilience, and retention of these foundation species and the critical ecosystem services they provide in shallow tropical seas. This project is committed to: 1) Educating and exciting influential business and civic leaders about conservation and restoration of coastal marine systems before these systems lose ecological function and value. This will involve influential Rotary clubs within North Georgia/Atlanta (the major economic engine of the southeastern US) as an initial focus. 2) Using the Research News and Institute Communications Office at Georgia Tech and well-developed contacts with science writers to produce popular press pieces on important ocean ecology discoveries emerging from these studies. (3) Organizing a public workshop of internationally prominent scientists focused on Maintaining Marine Biodiversity as a Strategy to Sustain Ecosystem Services and Coastal Cultures and Economies. A previous effort like this, organized by the investigators, attracted about 200 attendees and was webcast to numerous high schools in Georgia and to foreign investigators in less developed countries that could not attend. Speakers also conducted in-person video interviews with local high school classes. Due to that success, this model will be repeated. 4) Working with an association of educators and cultural leaders in French Polynesia to produce electronic format presentations on our work and on reef conservation that are appropriate for use by both teachers and leaders within Polynesian culture.</p>
<p>Ecologists have excelled at demonstrating the importance of direct (often negative) interactions among species pairs. However, when these interactions occur in a complex context among thousands of other species in the field, the sum of the many, poorly-known, indirect interactions can counterbalance, or even reverse, the better-known direct interactions, generating diffuse mutualisms instead of agonistic outcomes. In a proof-of-concept initial experiment, coral growth and survivorship were greater in coral polycultures than monocultures, especially during early stages of community development. Processes generating this outcome are unclear but understanding these is of critical importance as diversity and function of reefs decline and as humans need to predict and adapt to changing environments. This interdisciplinary investigation merges expertise in experimental field ecology, chemical ecology, and the ecology of microbiomes to investigate the functional role of biodiversity in coral reef ecosystems. Experiments use a novel coral transplantation method and field manipulations to assess: 1) whether greater coral species diversity enhances coral community performance, as well as growth and survivorship of individual corals, 2) whether greater genotypic diversity enhances coral performance within a species, 3) whether greater diversity of seaweed competitors further suppresses corals and enhances seaweed performance, and 4) the processes driving the patterns documented above, including the roles of disease, intraspecific versus interspecific competition, predators, mutualists, and differential access to, or use of, resources. The research investigates the relationship between biodiversity and ecosystem function across dimensions of coral taxonomic diversity, from species to genotypes, and creates a series of experiments elucidating general principles underlying ecosystem dynamics. Filling these knowledge gaps advances our fundamental understanding of how biodiversity influences ecosystem function at multiple scales and provides insight into the processes promoting coral coexistence in these species-rich ecosystems. Findings will have practical implications for coral management and restoration and may improve predictions regarding coral reef resilience and recovery in the face of changing climate.</p>
