“…This does not negate the importance of facilitative interactions between species at the same trophic levels (e.g. between primary producers (Bertness 1991; Bruno 2000; Bulleri & Benedetti‐Cecchi 2008), filter feeders (Dizon & Yap 2005), herbivores (Duggins 1981; Nishizaki & Ackerman 2007) or predators (Fodrie, Kenworthy & Powers 2008)).…”

Summary1. Positive species interactions are increasingly recognized as important drivers of community structure and ecosystem functioning. Although the literature on facilitative interactions in terrestrial environments has been reviewed and emerging patterns have been synthesized, comparable attempts are lacking for the marine realm. 2. By means of a quantitative survey of the literature, I provide a critical summary of current knowledge on positive species interactions in marine environments. In particular, I (i) assess how marine facilitation research compares to that carried out in terrestrial environments in terms of focus and philosophical approach; (ii) illustrate the mechanisms by which facilitation takes place in different habitats; (iii) assess whether benefactor and beneficiary species are more likely to belong to the same or to a different trophic level; and (iv) provide examples of how including facilitation into ecological theory might advance our understanding of the mechanisms that regulate ecosystem functioning. 3. Except for some studies in intertidal habitats, few studies in marine environments have been framed within mainstream facilitation theory (e.g. the Stress Gradient Hypothesis) and research does not seem to be organized in a self-contained theme. Amelioration of physical conditions appears to be the most common mechanism of facilitation in intertidal habitats, whilst associational defence predominates in the subtidal. 4. In contrast to the terrestrial literature, dominated by plant-plant interactions, marine benefactors and beneficiary species often belong to different trophic levels. This might imply little overlapping of resource niches or a differential response to environmental conditions or consumer pressure, with implications for the persistence of facilitative effects at the extreme ends of stress gradients. 5. Recent research shows that facilitation can enhance temporal variability and invasibility of marine communities and emphasizes the central role of positive species interactions in regulating the functioning of natural ecosystems. 6. Synthesis. Studies encompassing a wide variety of life histories and environmental conditions are central to achieving a unified facilitation theory. Research in marine environments can provide new insights into the mechanisms underlying variations in the strength and direction of species interactions, but this will require greater awareness and consideration of facilitation.

“…While growth and survival are important in the evaluation of restoration efforts, they are not the only criteria by which reef restoration success should be measured. For example, other areas that require further research include the optimal density and arrangement for coral transplantation, the most appropriate species—or combinations of species—for transplantation, the most suitable time of year to transplant and the effect of fragmentation and transplantation on reproduction (Rinkevich & Loya 1989; Dizon & Yap 2005; Okubo et al 2005; Sleeman et al 2005).…”

How Quickly do Fragments of Coral “Self‐Attach” after Transplantation?

Transplantation of coral fragments is seen as a potential method to rapidly restore coral cover to areas of degraded reef; however, considerable research is still needed to assess the effectiveness of coral transplantation as a viable reef restoration tool. Initially, during restoration efforts, coral transplants are attached artificially. Self-attachment (i.e., growth of coral tissue onto the substrate) provides a more secure and lasting bond, thus knowledge about self-attachment times for corals is of importance to reef restoration. While it is known that coral fragments may generate new tissue and bond to substrata within a few weeks of transplantation, surprisingly little is known about the speed of self-attachment for most species. Two independent experiments were carried out to examine the self-attachment times of 12 scleractinian and one nonscleractinian coral species to a natural calcium carbonate substrate. The first experiment examined times to self-attachment in 11 species of differing morphologies from seven families over approximately 7 months, whereas the second experiment examined three fast-attaching Acropora species over approximately 1 month. In the first experiment, the branching species Acropora muricata had a significantly faster self-attachment time compared to all other species, while Echinopora lamellosa had the slowest self-attachment time. For the second experiment, A. muricata was significantly slower to self-attach than Acropora hyacinthus (tabular) and Acropora digitifera (corymbose-digitate). The results suggest that a combination of factors including growth rates, growth form and life history may determine how quickly fragments of coral species self-attach after fragmentation and transplantation.

“…Coral reef ecosystems face a variety of threats from land and marine based anthropogenic activities (Peter et al, 2014;Ali et al, 2013;Balakrishnan et al, 2012;Sheikh et al, 2007;Sheikh et al, 2009b;ISRS, 2004;Albanis, 2004, Lamoree et al, 2002;Biselli et al, 2000), global warming (Peter et al, 2014) as well as competition for survival (Ferrier-Pages et al, 2011;Amar et al, 2008;Dizon and Yap, 2005) which cause deterioration of coral reefs and other marine resources.…”
