The sources of variation in this experiment were: Season = fixed factor with four levels (spring, summer, fall and winter). Gladfelter WB (1982) White-band disease in Acropora palmata: Implications for the structure and growth of shallow reefs. 3). A. cervicornis grew faster [3.1 ± 0.44 cm/month (= 37.2 cm/y)] compared to A. prolifera [2.6 ± 0.41 cm/month (= 31.2 cm/y)], and growth was significantly higher during Winter-Spring compared to Summer-Fall for both taxa (3.5 ± 0.58 vs. 0.53 ± 0.15 cm/month in A. cervicornis, and 2.43 ± 0.71 vs. 0.27 ± 0.20 cm/month in A. prolifera, respectively). Healthy Elkhorn coral can grow up to 13 cm (5 inches) in branch length a year, making them one of the fastest growing coral species. Growth was higher during the cold months of the year, probably resulting from the diversion of resources for reproduction during the summer months. Roving herbivore observations were only recorded at the level of plot due to their fleeting grazing patterns. The research team classified corals into six groups based on their growth forms. These differences were mainly due to damselfishes (especially S. planifrons and S. diancaeus), which were more abundant in San Cristobal than in Mario, whereas the sea urchin E. viride was more abundant in Mario than San Cristobal (Fig. For univariate analysis, the complete model described above was considered, and the sums of squares (Type 3) for each source of variation were estimated by calculating Euclidean distances among all pairs of individual observations (i.e., replicated branches per colony, time, season, site and species). Six of the herbivores noted were damselfish from the genus Stegastes, except for the yellowtail damsel Microspathodon chrysuris. For A. formosa at 5 m, the mean yearly extension rate was 8 cm per year ( Oliver et al., 1983 ), which for 2 months, would be 1.3 cm assuming a constant light regime. Nubbins were individually weighed to the nearest 0.001 g by suspending them on a tray below a semi-micro balance (Shimadzu AUW220D, Japan) in a water bath at ~25 OC. A similar size‐dependent variability in growth rate was observed in juvenile Acropora millepora corals of different size classes outplanted at different times (Guest et al. All surveyed colonies of A. cervicornis showed similar signs of predation throughout the experiment (damselfish bites, snail and fireworm). NOAA-NMFS and NCORE—RSMAS. Bull Mar Sci 32: 639–643. These colonies grow 5-10 cm (2-4 inches) each year, reaching maximum size in 10 to 12 years. Growth rate was monitored using linear measurement techniques. View Article Google Scholar 8. 2A). Populations were reduced to a few surviving colonies or fragments that in many localities had to compete with encroaching algae due to a lack of herbivory because of overfishing and the mass-mortality of the black sea urchin Diadema antillarum (Lessios, Robertson & Cubit, 1984). Only 30–40% of A. prolifera showed evidence of predation during the initial survey time, with the highest increase to 71% only at Mario (Table S1). All colonies in these three localities were wiped out by the intense thermal anomaly of 2005, which produced widespread bleaching and disease outbreaks in the area (Weil, Croquer & Urreiztieta, 2009). These rates are significantly higher than those reported for A. cervicornis in Barbados (14 cm/y) (Lewis, 1974) and in Jamaica (12–26 cm/y) (Tunnicliffe, 1983) and explain in part the fast growth and colony sizes observed from 2010 to the present study. Healthy-looking colonies of similar size (1–2 m in diameter) were selected during preliminary observations one month prior to the commencement of this investigation (August 2015) and marked with a numbered tag on a rebar hammered into the adjacent sandy substrate. Understanding population demographics of A. cervicornis and the hybrid A. prolifera in southwest Puerto Rico will aid future restoration and conservation efforts that could eventually support the recovery of this important structural complexity. This has provided a rare opportunity to evaluate some of the interactions proposed in the literature related to the relationship between damselfish and acroporids, coral health and mortality, and growth of the genotypes in those environments. The taxonomic differences in growth rates of corals were much better resolved using direct tagging. Each branch was randomly selected in each individual colony and marked at the base with a thin, colored cable tie (Fig. Only the thin and more abundant ecomorph was used in this study. This factor was included in the model to avoid simple pseudo replication (see Hurlbert, 1984) when comparing seasons. In the Caribbean region, a mostly disease induced (white band disease) mass-mortality of Acropora palmata and A. cervicornis started in the late 1970’s, wiping-out over 90% of these species throughout the region (Gladfelter, 1982; Knowlton, Lang & Keller, 1990; Aronson & Precht, 2001). The growth rates of actively growing apices were normally distributed and showed a high variability, with an average coefficient of variation of 58%. S1). Despite the territorial guarding behavior of the damselfish within their algal gardens, the Acropora patches support a diverse fish assemblage and provide shelter for several juvenile species of omnivores. An important piece of information missing in this study is the genetic diversity of these populations and how this affects growth and mortality rates (disease susceptibility). Increased phosphate levels increase growth rate in Acropora muricata - Research published in the upcoming January 2012 issue of the Journal of Experimental Marine Biology and Ecology documents an interesting find: increasing phosphate levels positively impacted the growth rate of Acropora muricata. It had overall, better environmental conditions (water quality/clarity, circulation, protection from storm surge and waves, and high illumination) compared to the other two sites. Vectors indicate species that were correlated (>0.7) with either site or time of ordinations. A hardy Acropora with rapid growth. in A. cervicornis, a marked increase in white band disease (WBD) and coral tissue mortality was observed. The combined impact of these stressors has produced drastic biological, ecological and structural consequences, leading to significant declines in live coral, community shifts and the collapse of the three-dimensional (acroporids) structure in many Caribbean and Indo-Pacific coral reefs (Aronson & Precht, 2001; Weil, Croquer & Urreiztieta, 2009; Hughes et al., 2018). This is a sharp contrast to Media Luna and Mario where up to ten urchins per plot and sampling time were quite common, and counts into the low thirties at Mario were recorded on two occasions and two separate plots. All colonies tagged in San Cristobal, Media Luna and Mario reefs seemed to be the product of new sexual recruitment after the bleaching event of 2010. If you are following multiple publications then we will send you present a high-resolution genome of the coral Acropora millepora (see the Perspective by Bay and Guerrero). Many A. cervicornis colonies that were surveyed prior to the investigation did not show signs of heavy algal accumulation; therefore only three branches were marked, which was the most branches already with algal overgrowth that could be found at each plot during the initial survey. This fact potentially makes it an optimum site for future nursery or propagation activities of the acroporid species complex in the LNPR. Nicholas M. Hammerman and Rebecca L. Becicka conceived and designed the experiments, performed the experiments, analyzed the data, prepared figures and/or tables, authored or reviewed drafts of the paper, and approved the final draft. 2D). Recent significant recovery of several back reef populations of A. cervicornis and the F1 hybrid A. prolifera were observed and investigated for over three years in two reef localities in southwest Puerto Rico (Lucas & Weil, 2015). Later stages of foliose algae have a greater potential to negatively affect the coral colony itself and are not as palatable to most herbivores (Littler, Taylor & Littler, 1983). Montipora requires both clean water and consistently high-levels of major ions to maintain their growth rate. PERMANOVA results based on Euclidean distances on mortality (% of dead tissue per colony) for acroporids testing for the effect of: Period (Pe) = Start and end of study; Sites (Si) = Mario and San Cristobal (no A. prolifera found in Media Luna) and Species (Sp) = A. cervicornis and A. prolifera. They are also highly sought after by reef tank hobbyists, commonly titled the “crown jewel of the SPS world” due to their intense colouration and remarkable growth rates. 3). Most Acroporas grow up to 20 inches (51 cm), but depending on the species some Acropora corals can get up to 10 feet. The highly heat tolerant A. hyacinthus variant “HE” increased in area an average of 2.9% month −1 (0.03 cm average mean radial extension month −1 ). Marine Sciences, University of Puerto Rico, Gehrmann Laboratories, University of Queensland, This is an open access article distributed under the terms of the. Colors of Acropora Corals - the radial polyps 6). Algal overgrowth was measured for A. cervicornis only (cm) (3 replicates per plot, 10 replicates per site), and algal composition (i.e., crustose coralline algae or Dictyota sp.) Univariate response variables were: linear growth and algal accumulation, whereas the multivariate data set was the structure and composition of fish assemblages. You can add specific subject areas through your profile settings. Average growth-rate of the transplanted corals was less than one-half that of the control group, which grew 10 cm. The growth rates of juvenile G. aspera, P. sinensis and A. millepora (1.5-6.8 mm mean diameter in the first year) are considerably slower than those of juveniles from planulating species (greater than 10 mm diameter). Principal Coordinate ordination plots by sampling time (PCO1) and site (PCO2). This was time zero for the assessment of linear growth and volumetric increase. On the other hand, A. prolifera could potentially persist through mild to moderate storm events due to its skeletal density and observed hardiness and continue to provide essential fish habitat and further reef recovery. A. prolifera did not have any conspicuous macro-algae overgrowth during the time of the study; observations in other areas indicate that algae-overgrowth is not common on colonies of A. prolifera in La Parguera. Conspicuous changes in algal species composition occurred when Dictyota spp. It is recommended to place new corals under lower light intensity than usually required. By contrast, the three less tolerant species averaged 6.1% (0.07 cm average mean radial extension month −1 ). However, species of the genus Acropora grow relatively fast: branches can grow more than 100 mm /year. This deterrence, as well as the potential grazing habitat, may provide enough preferential resources and habitat to maintain the reef environment in an intermediate healthy steady state, and continue to support the diversity of acroporid-associated fish and invertebrates. However, no tissue mortality associated with this condition was observed. In this study, the status of three recovering populations of A. cervicornis and two of A. prolifera were assessed over one year using coral growth and mortality metrics, and changes in their associated algae and fish/invertebrate communities in three localities in the La Parguera Natural Reserve (LPNR), southwest coast of Puerto Rico. These updates will appear in your home dashboard each time you visit PeerJ. The composition and abundance of fish and invertebrate assemblages (herbivores, omnivores and coralivores) associated with each plot was evaluated monthly. Although not considered in the overall spatial and temporal analysis due to their lack of site fidelity central to this study, it is important to note that many of the parrotfish species were encountered regularly at all sites. The following information was supplied regarding data availability: The raw data is in the Supplemental Files. PeerJ promises to address all issues as quickly and professionally as possible. Growth of Acropora tenuis juveniles. In this study we selected widely separated colonies (>10 m) and survey sites (>1,000 m) to avoid as much as possible the selection of clones. In contrast, A. cervicornis was also growing fast in Mario, but it was barely keeping ahead of the mortality produced by disease, predation and algal factors, thus any increase, or additional stress that affects growth, (e.g., bleaching, an increase in tissue mortality or a combination of these) would likely tilt the balance to total branch and colony mortality. Acropora species display the widest range of growth forms than any other coral genus, including stubby branches, elegant tables, giant plates, feathery spirals and less commonly, massive growth formations. This factor is orthogonal to all above and was considered in the model to test the main null hypothesis of this study (i.e., no differences between species). Lower disease prevalence in A. prolifera might indicate it is more resistant to diseases. Good survival of both species (>96%) as well as average tip growth rates of A. cervicornis- (2.62 ± 0.15 mm/month) and surface growth of A. palmata (23.65 ± 5.6 mm2/month) fragments, are comparable with similar studies of Caribbean coral nurseries. 6) because of lower disease prevalence, lower predation and no macro-algal overgrowth. The highest relative proportion of S. planifrons (35.09%, Table 3) was found in San Cristobal. 4). San Cristobal had the healthiest and faster growing populations of both taxa. Coral reefs are the most diverse and complex marine habitats on the planet and provide major ecological services to other important coastal and oceanic communities, and to human beings (Naeem, 1998; Huntington et al., 2017). In comparison, in Mario reef, which is about 2.2 km from the mainland, populations are growing in deeper (4–5 m), coarse sandy bottom and hence, the lower growth rates observed. A. hyacinthus, average growth rates range from \3 to 10 cm diameter increase per year, with much of this variation thought to be a response to temperature, in addition to competition and other abiotic and biotic factors (Tomascik et al. Acropora corals are one of the primary reef builders in world's oceans and they are highly sought after by reef tank hobbyists for their remarkable growth rates and intense colors. PERMANOVA results showed that there was a significant and independent (i.e., no interaction) effect of the main factors (Site and Season) on the accumulation of algae (Table 2). Analyses on patterns of spatial and temporal variation of these assemblages showed a significant effect due to site, but not to the temporal factors (Table 4). Series of apices of Acropora pulchra from an intertidal reef at Phuket, Thailand, were grown at different depths in the sea, and the length growth was monitored at 12–24 h intervals with laser diffraction. For these analyses, algal growth was not discriminated among species. Acroporids are the fastest growing coral genus in both the Caribbean and the Indo-Pacific, providing the physical and biological foundation for many shallow water coral reef communities (Lirman, 1999; Aronson & Precht, 2001). In addition to the first order interaction described above, there was a significant and independent effect of species, where linear growth rates were consistently and significantly higher in A. cervicornis [3.1 ± 0.44 cm/month (= 37.2 cm/y)] compared to A. prolifera [2.6 ±0.41 cm/month (= 31.2 cm/y)] (Table 1, Fig. Mario (open circles) reef had higher densities of, Coral tissue mortality (predation + disease) based on relative cover (%) of dead versus live tissue in the tagged branches averaged across colonies estimated from the difference in tissue mortality at the beginning (09/2015) and end of the study (08/2016). (A) Average linear growth rate (cm/month + SE) of. Patterns of multivariate variation across sites and times were illustrated using Principal Coordinate Analyses (PCO) using the routine PCO. After the corals have spent adequate time in the acclimation water, gently place the corals to a new environment. Acropora, for example, average linear extension recorded using direct tagging was 4.15 mm/month, compared to 3.40 mm/month for corals stained using Alizarin Red. White band disease (WBD) was common among all sites. Frags of this beauty are roughly 3/4"-1". A. prolifera has a shorter and denser branching pattern compared to the open, long branches of A. cervicornis. 2F–2I)) habitat in Mario, compared to shallow San Cristobal and Media Luna (Fig. U. of Miami, Biochemistry, Biophysics and Molecular Biology, PeerJ (Life, Biological, Environmental and Health Sciences), PeerJ - General bio (stats, legal, policy, edu), Permutational Multivariate Analysis of Variance (PERMANOVA), Wiley StatsRef: statistics reference online, White-band disease and the changing face of Caribbean coral reefs, Physical, and biological drivers of coral-reefs dynamics, Coral reefs at the crossroads, coral reefs of the world, Proceedings of the 11th International Coral Reef Sympoisum, Ft.

Overall, results indicate variability in both growth and mortality rates in both taxa across localities and seasons, with A. cervicornis showing overall higher mortalities compared to A. prolifera. 2H and 2I). This is especially true within the Caribbean after the disappearance of the acroporids and Diadema due to the onslaught of disease epizootics, bleaching events, overfishing and other anthropogenic impacts (Aronson & Precht, 2001; Precht et al., 2002; Weil & Rogers, 2011; Jackson et al., 2014; Weil, Rogers & Croquer, 2017). Ultra Coral Australia is a World Leading Supplier of sustainably sourced, Premium Rare & Exotic Australian Coral Colonies and Marine Logistical Services for industry & Government on the Great Barrier Reef, based in Mackay, Australia. Higher algae cover expansion during the summer months was observed in colonies at Mario reef, where higher densities of the sea urchin Echinometra lucunter, higher proportion of fish bites, and higher prevalence of disease were observed compared to the other two sites. Start­ing from a sin­gle em­bry­onic cell, it has been found to reach 5.1 mm in di­am­e­ter dur­ing a pe­riod of 9.3 months (Du­bin­sky, 1990). Mario is a ring shaped patch reef with a shallow breakage area to the east and southeast, and a shallow, sand and rubble lagoon (3–4 m deep) with an eastern open narrow channel (Fig. They have been presumably recolonized by sexual recruitment and therefore, different genomes. Contrary to what was observed for growth and some health indicators, there were no clear temporal patterns of variation of fish assemblages associated with acroporids in the study sites (Fig. Algal succession by more aggressive and dominant species may be subdued by the farming behavior of damselfish (Ferreira et al., 1998), and thus lead to a continual presence of early stages of filamentous algae, rather than the more foliose species that could potentially smother the recruiting and recovering acroporids. Overall, results showed that recovery of the acroporids seems to be species and site specific, and attempts to thoroughly conserve and or restore populations of these foundational taxa need to consider the recent history of targeted populations, their genetic variability, variable environmental and ecological stressors and anthropogenic impacts before developing nurseries and/or providing further protection to natural populations of these acroporids. This taxon also showed no algal overgrowth, and significantly less predation signs and tissue mortality compared with A. cervicornis, which had significantly higher tissue losses due to damselfish territories, higher disease prevalence, higher predation and overgrowth by macroalgae. They are also highly sought after by reef tank hobbyists, commonly titled the “crown jewel of the SPS world” due to their intense colouration and remarkable growth rates. This morph has a deep pink-red coloration on its tips and a mint green base. Additionally, the hybrid A. prolifera has been described in previous studies as having high hybrid viability, lower adult mortality, lower disease prevalence, higher tolerance to variable environmental conditions, and higher branch density than A. cervicornis (Bowden-Kerby, 2008; Fogarty, 2012. (4) Growth rates of A. millepora were assessed as differences in buoyant weight over time (Davies 1989). Tissue mortality (estimated as the relative cover of dead tissue compared to live tissue), varied between the species and across sites (Fig. Many strategies have been implemented to foster new Acropora growth, but success is highly variable and generally site-specific. When the vessel becomes full , replace the water with the new environment water by a small amount at a time. Weil E, Hammerman NM, Becicka RL, Cruz-Motta JJ. Algae do not typically settle on healthy tissue, and several health-impairing factors contributing to tissue mortality help to pave the way for algal overgrowth and smothering. It is important to note that while A. cervicornis has a higher growth rate, their elongated and branching structure makes them more susceptible to breakage during localized storm events. There was limited evidence of recent increases in growth rates of corals, rather growth rates of Pocillopora were much lower than expected. Low population levels and a lack of significant recovery for roughly 30 years, led to A. palmata and A. cervicornis being listed as critically endangered under the IUCN Red List of Threatened Species (Aronson et al., 2008). Other colonies in these areas have survived partial mortalities and disease since 2005, when they grew from new sexual recruits. Elkhorn coral can span a diameter of 4 m (12 feet) wide and 2 m (6 feet) tall. Once each plot was located and before measurements were taken, a timed underwater visual census commenced when the diver was approximately 2–3 m from the colonies. This project was funded by the Department of Marine Sciences, University of Puerto Rico. 2014). E. viride had higher relative abundances at Mario and Media Luna compared to San Cristobal (Table 3). Cephalopholis fulva was also considered within this category given that only the juvenile life stage was encountered, albeit not frequently. 1). thank you in advance for your patience and understanding. All analyses (univariate and multivariate) were performed using the routine PERMANOVA (Anderson, 2017). Winter and spring months are relatively rainless (dry season) in southwest Puerto Rico, therefore nutrient input from rain water runoff is minimum, thereby limiting algae growth. PERMANOVA results based on Euclidean distances on mean growth rate for the two acroporids, to test for the effect of: Season (Se), Fall, Winter, Spring and Summer; Sampling time (Ti), 2 to three nested per season; Sites (Si), Mario and San Cristobal (no A. prolifera found in Media Luna) and Species (Sp). The Raspberry Shortcake Acropora is similar to the Strawberry Shortcake variety. Percentage cover of dead areas increased in all sites and for both species through the length of the study, with the greatest increase in A. cervicornis at San Cristobal (Fig. obs., 2016) was common in Media Luna and San Cristobal colonies, largely affecting A. cervicornis. A. cervicornis consistently grew faster than A. prolifera across all three study sites during our study period. Small, medium and large thickets of A. cervicornis and its associated hybrid A. prolifera were abundant at San Cristobal (17.93N, −67.11W) and Mario reefs (17.95N, −67.05W), while only A. cervicornis was present at Media Luna (17.95N, −67.05W). Growth of Acropora tenuis juveniles. Permutation analysis of variances (PERMANOVA) showed a statistically significant first order interaction between ‘site’ and ‘season’ for growth rates (Table 1), indicating that temporal differences depended on the site being sampled. Changes in light quantity and quality and water motions affect growth rates and growth morphologies in most coral species. 5). Each plot (10 replicates per site) was treated as a whole rather than each colony separate because of the behavioral nature of roving herbivores, which may shortly visit each taxa in passing. Acropora displayed at least two fold higher growth rates, significantly greater than other genera, whereas Pocillopora had the lowest growth rate. 2C). It is highly recommended to acclimate all corals to a new environment to prevent shocking corals. Three branches were marked for algal growth with fluorescent string in each colony of A. cervicornis to assess algal accumulation and associated coral mortality over time (Figs. Although intermediate morphotypes of the hybrid have been reported, all those observed and selected for these sites appeared very similar in shape and branch size/density. Multifactorial, mixed analyses of variance based on permutations were done to test various hypotheses related to potential differences between species and whether those differences were consistent across different spatial and temporal scales. J Paleontol 40: 233–240. It is for this reason they are also known as one of the most challenging yet rewarding coral aquarium species.”. Historically, acroporids have provided the essential complexity that: (1) allowed successful recruitment and development of juvenile reef fish and invertebrates (including commercially important species); (2) contributed to coastal protection and sediment stabilization; and (3) fostered biodiversity and ecosystem productivity. Furthermore, results are similar to those just published for a multi-year study in Florida (Goergen et al., 2019). 6, Table S1). Branches were chosen based on the presence of already established algal accumulation (>1 cm). Right after we finished our surveys, hurricane Mathew passed 250 km south of Puerto Rico and produced significant swells that uprooted and fragmented all colonies in Media Luna, but did very little damage (few colonies turned over) at Mario or San Cristobal. Although the damselfish farming behavior encourages the continued growth of algae, their preference for turf algae may slow the growth of later stages and more foliose species. You can also choose to receive updates via daily or weekly email digests. San Cristobal and Media Luna are shallow (1–2 m) back reef habitats with a coarse rubble and sand substrate. Acropora colonies can display in almost any hue of the rainbow, with light-coloured branch tips where growth is occurring. S1). The bite injuries and further tissue mortality facilitates macro-algae growth and accumulation, as well as inducing focal infections of white band disease (Weil et al., 2002; Weil et al., 2002; Weil & Rogers, 2011). Taxa (species) = fixed factor with two levels (A. cervicornis and A. prolifera). The only exception (April 2016) at Mario, showed a significant decrease, but this was due to the breakage of tips of tagged branches (Fig. Being produced after the disease and bleaching impacts, we assume that most of these genotypes were less susceptible than those that died in 2005–10. With Members & Partners in every corner of the globe, at Ultra Coral Australia, if you’re passionate about Coral then you’re in the right place. Although Diadema were not encountered in our sample plots, the other species of urchins observed may play an important role in deterring the occurrence of algal phase shifts. Acro­p­ora mille­pora is a hard coral. It has been consistently shown that damselfishes rapidly colonize young and older acroporid colonies, and actively bite and kill polyps to establish their algae lawns and nesting territories (Potts, 1977; Suefuji & Woesik, 2001; Wilkes et al., 2008). The length of the branch was measured with a plastic ruler (cm) and photographed (Fig. Growth-rates, however, showed considerable variation. 3, Table 1). A. cervicornis had consistent problems with algal overgrowth, disease and higher damselfish bites and predation pressure, which resulted in higher mean tissue mortality compared to A. prolifera. A. cervicornis showed significantly higher (P < 0.022) proportion of colonies with predation signs compared to A. prolifera in all sites, with between 90% and 100% of colonies having evidence of predation. Each site was visited monthly from September 2015 to August 2016. This species was not found at any time at San Cristobal, and only found infrequently at Mario and Media Luna (Table 3). We Place the corals in the water from the packing bags and slowly add the water from new environment (Dripping method is recommended). Volumetric growth for each colony was measured and photographed from the top and from the side with a 20-cm scale at the beginning and end of this study to obtain overall volumetric growth differentials and mortality areas. They are most commonly found as branching corals, exhibiting axial and radial polyps. Climate change and wildlife diseases: when does the host matter the most?
