This factor was included in the model to evaluate whether the response variables considered in this study responded to clear changes of natural environmental conditions. Growth of Acropora pulchra Growth of Acropora pulchra Yap, H.; Gomez, E. 1984-08-01 00:00:00 The growth of both undisturbed colonies and transplants of the branching coral Acropora pulchra (Brook) was studied over a 17-month period in the reef of Bolinao, Pangasinan, northern Philippines. Acropora species are small polyp stony (SPS) corals, consisting of corallites around 2mm in size. As such, these foundational species have received much attention from NOAA’s coral reef management plans, the Endangered Species Act and the IUCN Red list (Weil et al., 2002; Acropora Biological Review Team, 2005; Aronson et al., 2008). Download the Ultra Coral Australia App for FREE. Even though Acropora cervicornis and the hybrid A. prolifera are the fastest growing coral species in the Caribbean, populations have failed to recover region-wide, 35 years after the disease-induced mass mortalities (Precht et al., 2002; Mumby et al., 2006), with only a few populations now covering large areas (Vargas-Ángel, Thomas & Hoke, 2003; Keck et al., 2005; Busch et al., 2016; D’Antonio, Gilliam & Walker, 2016). 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. In contrast to our results, Bowden-Kerby (2008) reported higher growth rates for A. prolifera compared to A. cervicornis for the same area in La Parguera, which indicates that growth rates are probably highly variable across habitats and over time for both taxa, and single-year data might be limited to address growth and survivorship over mid- to long periods of time. These were recorded as present or absent for the entire colony, assuming the whole colony is equally susceptible to each of these variables. PERMANOVA results based on Bray Curtis dissimilarities (Squared root transformed and standardized by total) on assemblages of fish associated with the acroporids and testing for the effect of: Season (Se), Fall, Winter, Spring and Summer; Sampling time (Ti), two to four nested within season, and Sites (Si), Mario, San Cristobal and Media Luna. Soon after the mortality, the tri-dimensional, complex structure collapsed, significantly reducing essential fish habitat and niche availability for other invertebrate species, which impacted biodiversity and trophic dynamics in shallow Caribbean coral reefs (Knowlton, 1992; Weil et al., 2002; Acropora Biological Review Team, 2005). Continued arrows indicate temporal changes. The red sea urchin, Echinometra viride, was the only macro-invertebrate living within A. cervicornis colonies across all sites and times (Table 3, Fig. Acropora downingi , the dominant species of the coral reef of Hengam Island, were compared in autumn 2011. 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). Overall, the growth of Acropora pulchra branches over an 8 week period in this field study was comparable to that reported for Acropora formosa transplantation experiments. It is recommended to place new corals under lower light intensity than usually required. Elkhorn coral can span a diameter of 4 m (12 feet) wide and 2 m (6 feet) tall. By contrast, the three less tolerant species averaged 6.1% (0.07 cm average mean radial extension month −1 ). The growth rates of the corals under the heated conditions were not significantly different from those of the ambient group (P = 0.32 at 30 °C, P = 0.86 at 32 °C, Wald test under GLM). S1). Growth was higher during the cold months of the year, probably resulting from the diversion of resources for reproduction during the summer months. 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. overgrew branches during the summer months (Figs. 5). 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. Growth rate Branching corals of the genus Acropora are among the fastest-growing taxa on most coral reefs. On average, colonies of A. cervicornis increased by 4.17 ± 1.71 m3/year across all three sites and A. prolifera increased by 4.39 ± 1.34 m3/year across two sites. There was limited evidence of recent increases in growth rates of corals, rather growth rates of Pocillopora were much lower than expected. A total of twelve herbivorous fish species were identified and recorded based on their regularity of encounters at all sites (Table 3). Growth was estimated using Gompertz growth functions: the general form is: where y is the size, a is the maximum size asymptote, b is the displacement of the curve along the x-axis, c is the growth rate, and t is time. Tissue mortality (estimated as the relative cover of dead tissue compared to live tissue), varied between the species and across sites (Fig. We Corals in the larger size class had a higher growth rate than corals in the smaller size class. Data was square root transformed to down weight the contribution of abundant species. 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. Acropora millepora is a hard coral. The research team classified corals into six groups based on their growth forms. Unexpectedly, linear 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). View Article Google Scholar 8. Growth dynamics in Acropora cervicornis and A. prolifera in southwest Puerto Rico. Natural population recovery of Acropora palmata, A. cervicornis and their hybrid, Acropora prolifera, have fluctuated significantly after their Caribbean-wide, disease-induced mass mortality in the early 1980s. Vectors indicate species that were correlated (> 0.7) with either of the two first axis of ordinations. Average growth-rate of the transplanted corals was less than one-half that of the control group, which grew 10 cm. Each site was visited monthly from September 2015 to August 2016. This balance seems to be pushed to the high mortality side often by increasing frequency of high thermal anomalies, inducing bleaching and disease outbreaks and other factors, which have historically impacted the natural recovery of these taxa in the La Parguera Natural Reserve in Puerto Rico and possibly other areas in the region. S1). Acropora species in general, reach sexual maturity within 3 to 5 years, with a branch diameter of 1.5 - 2.75" (4 - 7 cm). 3). 2D). The length of the branch was measured with a plastic ruler (cm) and photographed (Fig. 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. 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). It is for this reason they are also known as one of the most challenging yet rewarding coral aquarium species.”. The significant sources of variation for mortality was period and site (i.e., start to end of the study, and site (Table S1)). If you are following multiple publications then we will send you 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. A. cervicornis presented two different growth morphologies (ecomorphs) in the area: one characterized by thin, long and slender, yellowish branches (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.

The tissue loss occurring without the subsequent algal accumulation could, on a short temporal basis, be attributed to urchin grazing, but in the long term could signify a more positive outcome for the recovery of healthy tissue given that urchins are not deterred by damselfish nor are they as particular about the algae they feed upon (Littler, Taylor & Littler, 1983). 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). Weil E, Hammerman NM, Becicka RL, Cruz-Motta JJ. It grows into compact, low profile thickets with little inter-branch space (Fig. 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. The sources of variation in this experiment were: Season = fixed factor with four levels (spring, summer, fall and winter). 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. Only A. palmata have been reported and/or observed to have had good recovery in just a few localities (Lucas & Weil, 2015). Although corals grow relatively slowly in general (often less than 1 cm year −1), under optimal conditions, the growth rates of branching corals in the genus Acropora can exceed 10 cm year −1 (Lirman et al., 2010). Branches were chosen based on the presence of already established algal accumulation (>1 cm). This species was not found at any time at San Cristobal, and only found infrequently at Mario and Media Luna (Table 3). Lower disease prevalence in A. prolifera might indicate it is more resistant to diseases. 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). Due to gaps in the photographic record and reduced sample sizes, colonies that survived four years or longer were combined into a single group. Ensure the water temperature matches with the new environment’s water. Changes in light quantity and quality and water motions affect growth rates and growth morphologies in most coral species. "Following" is like subscribing to any updates related to a publication. Six species of omnivorous fish were also found regularly in association with Acropora colonies at all sites (Table 3); two of which, Haemulon flavolineatum and Holocentrus adscensionis, were most frequently observed sheltering within the branches. 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. They are most commonly found as branching corals, exhibiting axial and radial polyps. Out of those multiple sites, three were chosen in the La Parguera Natural Reserve (PNR), Puerto Rico (Fig. 6, Table S1). 3D–3F). 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). This factor was included in the model to avoid simple pseudo replication (see Hurlbert, 1984) when comparing seasons. 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). Results of this study show the seasonal growth dynamics of both A. cervicornis and A. prolifera and the impact of natural, common stressors over a short period of time (one year). 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. Recovery of the acroporid complex seems to be species and site specific, and is highly influenced by environmental variability, so attempts to thoroughly conserve these foundational species should consider targeted populations, localities, bathymetry, ecological and anthropogenic stressors, and the genetic variability of the target populations before developing recovery/protection plans. Conspicuous changes in algal species composition occurred when Dictyota spp. After one year, the mean annual linear growth rate was 52.5 ± 1.1 cm/yr and the average In this case, a Bray-Curtis similarities matrix calculated on the square rooted transformed data was the basis of multivariate analyses. 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. Growth rates (linear and maximum diameter) and survival of 712 colonies were monitored for one year examining the effects of genotype, depth and attachment method. Note: You are now also subscribed to the subject areas of this publication After 10 days, juveniles of all three species contained zooxanthellae. Nevertheless, a posteriori comparisons of this interaction showed a significantly higher growth rate during winter/spring (for both species and in all sites) compared to summer/fall (Fig. Acropora formosa and A. nobilis, was observed during March-August 2013. and Acanthurus coeruleus). 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. Ernesto Weil conceived and designed the experiments, performed the experiments, prepared figures and/or tables, authored or reviewed drafts of the paper, and approved the final draft. PeerJ promises to address all issues as quickly and professionally as possible. San Cristobal had the healthiest and faster growing populations of both taxa. 1). 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). Our results showed sub -normal growth rate of inversely transplanted fragments and provided some basic knowledge about the growth rate Climate change and wildlife diseases: when does the host matter the most? Regarding the specific mechanisms regulating damselfish-Acropora interactions, populations of damselfish have exploded in many localities due to the interactive effect of two processes: (1) lack of predators due to overfishing, and (2) availability of the newly created three-dimensional structure associated with the re-growth of acroporids, which provides refuge and habitat to the juveniles and then, the adults (Cole, Pratchett & Jones, 2008; Huntington et al., 2017). Natural population recovery of Acropora palmata, A. cervicornis and their hybrid, Acropora prolifera, have fluctuated significantly after their Caribbean-wide, disease-induced mass mortality in the early 1980s. This was time zero for the assessment of linear growth and volumetric increase. All routines were done with the software PRIMER V7 and PERMANOVA add on Clarke & Gorley (2015). 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. However, these rates are similar and/or significantly lower to growth rates reported for different genotypes of asexually produced, nursery and field fragments in Florida, the Dominican Republic and other localities (25.6–80.6 cm/y) (Lirman et al., 2014; Schopmeyer et al., 2017). A little pseudo time lapse documenting SPS and Acropora growth in my reefer 250 over 2 years. Algal accumulation was only observed in A. cervicornis, and was higher during Spring-Summer compared to Fall-Winter (6.1 ± 0.91 cm/month and 3.8 ± 0.29 cm/month, respectively, (PERMANOVA, df = 2, MS = 10.2, p = 0.37)). This seems to be a clear indication of the diversion of resources from growth into reproduction (production of eggs) and spawning in both taxa. Place the corals in the water from the packing bags and slowly add the water from new environment (Dripping method is recommended). Growth of Acropora tenuis juveniles. Despite having a higher rate of disease prevalence, mortality and predation signs compared to the other two sites, San Cristobal populations consistently showed higher growth rates, which translated into higher growth and overall survivorship of both taxa. All were observed at each site at least once, apart from Sparisoma chrysopterum, the redtail parrotfish. Growth-rates, however, showed considerable variation. Criteria to define the sampling sites for our study, were based on: (1) the existence of long-term observations of environmental conditions, habitat type, and colony health status; and (2) relative abundance of A. cervicornis and A. prolifera (Lucas & Weil, 2015). present a high-resolution genome of the coral Acropora millepora (see the Perspective by Bay and Guerrero). This factor is orthogonal to all above and was considered to test the generality of potential differences observed between species. The only exception (April 2016) at Mario, showed a significant decrease, but this was due to the breakage of tips of tagged branches (Fig. 3, Table 1). 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. 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). Robust planar growth estimates were not obtained for Platygyra due to its morphology, but we report high survivorship of the colonies: 94% with no mortality as compared with 79% for Acropora … 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). Additionally the highly branching nature of A. cervicornis creates a more accessible refuge for several fish and invertebrate species as opposed to A. prolifera, however the proximity of each colony per plot favored potential mobility between the two. Cephalopholis fulva was also considered within this category given that only the juvenile life stage was encountered, albeit not frequently. Seasonal variation in all these variables needs further temporal replication, since storms, diseases, thermal anomalies, bleaching, predation and other anthropogenic impacts could skew results from a single season or year of study. Branches were measured monthly, together with observations to evaluate associated disease(s), algae accumulation and predation. 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). Good environmental conditions since 2010 might explain the significantly higher growth rates of these two taxa for this period compared to previous data, and to other areas in the Caribbean. Another condition termed “Acropora red band” which has been observed for some time now in LPNR (E Weil, pers. Our promise In the absence of thermal stress, the major stressors seem to be (in order of increasing importance): damselfish gardening behavior, algal smothering, predation by invertebrates (i.e., snails and fire-worms) and recurrent but low prevalence of WBD-like problems (Wilkes et al., 2008; Weil & Rogers, 2011; Goergen et al., 2019). After the fish were counted, the invertebrates present were also located and counted. Vectors indicate species that were correlated (>0.7) with either site or time of ordinations. 2008;Linares et al. Growth rates were on average lower than those reported for nursery fragments, but higher than most of those reported for wild populations in the region. 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. Each branch was randomly selected in each individual colony and marked at the base with a thin, colored cable tie (Fig. San Cristobal and Media Luna are shallow (1–2 m) back reef habitats with a coarse rubble and sand substrate. The taxonomic differences in growth rates of corals were much better resolved using direct tagging. 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). Copyright 2020 | Ultra Coral Australia | All Rights Reserved. Linear growth rates and total volume of each colony was determined using Coral Point Count (Kohler & Gill, 2006) with excel extensions as outlined by Kiel, Huntington & Miller (2012). Images are for illustration purposes only and please note that Coral species vary significantly from one to the next as far as colour, size and temperament. 1996; Wakeford et al. However, species of the genus Acropora grow relatively fast: branches can grow more than 100 mm /year. Most Acroporas grow up to 20 inches (51 cm), but depending on the species some Acropora corals can get up to 10 feet. Other colonies in these areas have survived partial mortalities and disease since 2005, when they grew from new sexual recruits. Roving herbivore observations were only recorded at the level of plot due to their fleeting grazing patterns. Fuller et al. A. cervicornis consistently grew faster than A. prolifera across all three study sites during our study period. “Acropora” is by far the most common contributor to our tropical coral reefs, with 149 species known to date. 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). thank you in advance for your patience and understanding. This genetic inference and the frontal reef-crest sheltering properties of selected reefs are important considerations for future selection of potential nursery or re-population areas in the LPNR or elsewhere. These updates will appear in your home dashboard each time you visit PeerJ. 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. 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. 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. The following information was supplied regarding data availability: The raw data is in the Supplemental Files. (A) Mario (17°95′N, −67°05′W), (B) Media Luna (17°95′N, −67°05′W), (C) San Cristobal (17°93′N, −67°11′W). 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. Eucidaris tribuloides was observed occasionally. Relative species abundance of associated organisms observed in the two.

Principal Coordinate ordination plots by sampling time (PCO1) and site (PCO2). When the vessel becomes full , replace the water with the new environment water by a small amount at a time. 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. A. prolifera, had lower overall mortality rates, yet the increase in mortality over the study period was higher compared to A. cervicornis for Mario colonies, 31% versus 22% increase, respectively. Although survivorship of transplanted corals is relatively high after a year or two, similar to natural populations, studies show high mortality in subsequent years due to a major stressor or to one of the synergistic effects mentioned above (Quinn & Kojis, 2006; Garrison & Ward, 2012). These investigations, along with results presented here, highlight the potential ecologically role that A. prolifera has in coral reef ecosystem recovery given the present state of coral reef ecosystems. Univariate response variables were: linear growth and algal accumulation, whereas the multivariate data set was the structure and composition of fish assemblages. Acropora displayed at least two fold higher growth rates, significantly greater than other genera, whereas Pocillopora had the lowest growth rate. 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. 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).
