acropora cervicornis behavior

One region where numerous large patches of A. cervicornis exist today is within the Southeast Florida Coral Reef Ecosystem Conservation Area and more specifically in Broward County, FL, at the northern-most extent of this species’ range (Vargas-Ángel et al., 2003; Walker et al., 2012; D’Antonio et al., 2016). Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. Monitoring methodologies were modified from a previously developed Acropora spp. Staghorn corals use their nematocysts which are located on their tentacles for eating and gaining food. corals off Belize using sub-meter satellite imagery classification. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Staghorn corals also eat planktonic animals which float by in the water (McGregor 1974). doi: 10.7717/peerj.541, Miller, M. W, Marmet, C., Cameron, C., and Williams, D. (2014b). Fragment counts at BCA were highest during TSI12 and WS16 where total fragment counts were over 300. Prior to the initial survey (June 2008), the boundary of each patch was mapped using a handheld GPS. Coral disease outbreak: pattern, prevalence and transmission in Acropora cervicornis. National Science Foundation Characterize the condition of previously known and newly identified large dense Acropora cervicornis patches in southeast Florida. doi: 10.3354/meps10996. Williams, D. E., Miller, M. W., and Kramer, K. L. (2006). Silver Spring, MD: NOAA Technical Memorandum NMFS-OPR-24, 199. IUCN Red List of threatened species: Acropora cervicornis. Mar. The occurrence of disease was significantly higher in 2015 during a widespread disease event affecting the entire Florida Reef Tract (Miller et al., 2016a; Precht et al., 2016). R Core Team (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 material is based upon work supported by the Damselfish predation significantly increased during the study for Scooter (glm, p < 0.05). These data indicate how wide-spread each condition was at each patch. Unfortunately, our data also indicate that prevalence of disease, predation, and fragmentation are increasing and having an even greater detrimental effect on the long-term persistence of this species. Taxon Information Mean prevalence and occurrence of disease, predation, and bleaching by plot at Scooter. Prevalence, consequences, and mitigation of fireworm predation on endangered staghorn coral. The trends in mean abundance of fragments, colonies, and masses were analyzed using a Poisson regression for both between monitoring events and years. Sci. Staghorn coral Acropora cervicornis (Lamarck, 1816) Description: Colonies loosely branching, all branches circular in cross section. Boxes represent the 25 and 75% quartiles with whiskers extending 1.5 ∗ interquartile range, the line represents the median, and dots are considered outliers. doi: 10.1007/BF00334481, Gignoux-Wolfsohn, S. A., Marks, C. J., and Vollmer, S. V. (2012). The frequency of disturbance events varied between years; however, during years of few or no disturbances such as 2013, both patches exhibited signs of recovery with increased PCL. A negative percent change in mean PCL was observed for a majority of the fall to winter and summer to fall monitoring periods. In particular, -Acropora cervicornis- is one of the primary reef building corals in the Caribbean (Birkeland 1997). Similar annual and seasonal patterns were found between patches for all conditions, although prevalence rates were higher at Scooter for all conditions besides damselfish predation and bleaching. Night Reef. Restor. Acropora cervicornis (Lamarck, 1816) Acropora Oken, 1815 Characters: Colonies may form stands several metres across. Masses were more affected by bleaching than colonies. Summer prevalence at Scooter was significantly higher than fall and spring (Tukey, p < 0.001), and occurrence counts were the lowest in the fall on both colonies and masses (Figures 5, 6). Snail predation was not observed at every monitoring event and increased significantly in prevalence toward the end of the study (2013–2016) at Scooter (glm, p < 0.01). doi: 10.1002/aqc.1146, Mercado-Molina, A., Ruiz-Diaz, C., Pérez, M., Rodríguez-Barreras, R., and Sabat, A. Both bleached and sanded skeletons were used in this experiment. The Raman spectroscopy test showed that there was no significant change in the Raman shift between the three branches tested. However, these gains were not enough to outweigh the total losses, and by area BCA experienced a net loss of 144 m2 of living A. cervicornis and Scooter 173 m2. Coral reef project–papers in memory of Dr. Thomas F. Goreau. When significant, multiple comparisons two-tailed post hoc tests were performed to determine significance between factor levels. Protect. Bleaching was more prevalent at BCA than Scooter, affecting up to 70% of the plots (Figures 5, 6). Conserv. One-way analysis of variance (ANOVA) was used to assess the differences in PCL between seasons. Acroporid corals with indeterminate arborescent growth like A. cervicornis primarily reproduce asexually by fragmentation, which can lead to extensive monotypic patches. It was the primary condition when present in 48 ± 5 and 34 ± 5% of the plots on average at BCA and Scooter, respectively. High-latitude Acropora cervicornis thickets off Fort Lauderdale, Florida, USA. Significant seasonal changes in the abundance of masses were observed at Scooter, with greatest changes observed in the summer (p < 0.05). Kruskal–Wallis test by ranks was used to explore absolute change in PCL. All individual areas (occurrences) of recent mortality within the plot boundary were counted based on cause (rapid tissue loss, white band disease, fireworm, and snail); recently dead areas separated by living tissue were counted as separate occurrences. Total fragments counted per monitoring event ranged from 15 to 359 at BCA (plot average = 6.3 ± 0.31 fragments) and 80 to 1,313 at Scooter (17.6 ± 0.73 fragments). This corallite is called the axial corallite and is a key feature which distinguished Acropora from other corals. | Acropora cervicornis recruit survival for three experimental treatments over the course of the 126-day study (Kaplan-Meier X 2 = 7.3, df = 2, p = 0.03).

Since this dramatic decline, recovery has been limited with few known high cover populations remaining throughout the species’ range (Vargas-Ángel et al., 2003; Keck et al., 2005; Grober-Dunsmore et al., 2006; Lirman et al., 2010; Walker et al., 2012; Busch et al., 2016). doi: 10.3354/meps301119. Absolute change in percent cover between monitoring events by site BCA (A), Scooter (B). Temporal variability was observed in mean percent live cover at both patches and showed an overall loss of tissue. BCA however, had a slight reprieve from disease and a small increase in percent cover, until Hurricane Matthew passed by in October 2016, further reducing PCL at both sites. Berkle, M. E. (2004). From January 2012 through 2016, only 5 days fell below 22°C, whereas from January 2009 through December 2011 there were 83 days below 22°C. Acropora cervicornis specimen collected 2011-07-11 from Middle Keys, Atlantic with a genomic DNA sample available at the Ocean Genome Legacy biorepository. Mar. Extreme changes in cover may not indicate a total loss of A. cervicornis tissue at the site. doi: 10.1007/BF02407510, Sussman, M., Loya, Y., Fine, M., and Rosenberg, E. (2003). A., Nedimyer, K., and Burkepile, D. E. (2016). Branches are round in cross-section, and sub-branches emerge nearly at right angles. Zooxanthellate (Ref. This coral is now uncommon, though it is probably the most common of the two ’staghorn’ corals in many parts of the Caribbean region. 20, 773–781. The most prevalent condition recorded for both patches, when all seasons and years were pooled, was fireworm predation followed by white disease, damselfish predation, snail predation, then bleaching.

White band disease transmission in the threatened coral, Acropora cervicornis. 92, 265–283. This may be even more prudent in high density areas where disease is more prevalent, because the etiology of these diseases is still unknown, and they could also be spreading by water movement or fish, by abating disease where it is most abundant would benefit the rest of the marine community. Ecology 40, 67–90. Goergen’s degree of Doctorate of Philosophy at Nova Southeastern University Halmos College of Natural Sciences and Oceanography. Mean prevalence and occurrence of disease, predation, and bleaching by plot at BCA. Condition characteristic data included: (1) estimates of percent cover of live A. cervicornis, (2) the presence and relative ranking of tissue loss caused by white band disease, rapid tissue loss (Williams and Miller, 2005), and predation by the bearded fireworm (Hermodice carunculata), three-spot damselfish (Stegastes planifrons), and the corallivorous snail (Coralliophila abbreviata), and (3) presence and severity of bleaching. colonies on dead structure, indicate that BCA is older and experienced cover decline prior to Scooter. Colors represent seasonal changes from Fall to Winter—blue, Winter to Summer—yellow, and Summer to Fall—red, the green bar represents change in cover between the SM12 and the TSI12 monitoring events. White-band disease in Acropora palmata: implications for the structure and growth of shallow reefs. Therefore, we suggest specific management actions such as the management of predator populations; this may not only lead to improved growth of colonies by reducing the number of damaged growth ends, but could also lead to a reduction in disease due to their abilities to be vectors of pathogens. Google Arts & Culture features content from over 2000 leading museums and archives who have partnered with the Google Cultural Institute to bring the world's treasures online. Prevalence and occurrence of disease and predation were highly variable between monitoring events. Occurrences were not counted for Damselfish predation. McGregor, .. 1974. Contribut. Coral Gardens Reef in Belize remains a refuge for Acropora spp. Increased presence of disease was maintained at Scooter into the following year, and while there was a decrease in occurrences, prevalence indicated that disease was still present across the entire patch at greater than average prevalence rates. While prevalence levels were chronic, the mean tissue lost per colony has been described as 3% (Goergen et al., unpublished). The year 2013 had the lowest mean maximum temperatures and significantly lower disease prevalence (Tukey, p < 0.01) and occurrence counts. Mar. Ser.

Chadwick, .. January 1999. Prevalence of fireworm predation was significantly higher in 2015 at both BCA and Scooter (Tukey, p < 0.001) and significantly lower in 2013 at Scooter (Tukey, p < 0.001). doi: 10.7717/peerj.2473. This dramatic decline leads to its listing as threatened under the United States Endangered Species Act (US ESA; National Marine Fisheries Service, 2006) and as critically endangered on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species (Aronson et al., 2008). Furthermore, under modern day reef condition and the frequent occurrences of storms and elevated winds, paired with seasonal and sometimes chronic disease and chronic predation, the ability for a population to grow into these large patches may be difficult. Demographic Monitoring Protocols for Threatened Caribbean Acropora spp. Nature 294, 251–252. To address these questions, two semi-continuous patches of A. cervicornis (>1 hectare each) were used to evaluate temporal patterns in species abundance, percent cover, and the presence, prevalence, and occurrence of disease, predation, and bleaching. 32, 639–643.

This work was made possible through the support of the National Coral Reef Institute by an award made to Nova Southeastern University from National Oceanic and Atmospheric Administration Coastal Ocean Program Award Number NA03NOS4260046, National Oceanic and Atmospheric Administration Award Number NA10NMF4720029 to the Florida Fish and Wildlife Conservation Commission, and Nova Southeastern University Presidents Faculty Research and Development Grant. To fully understand the population dynamics of this threatened species and to further inform restoration and conservation efforts, these data need to be evaluated over the long-term. EG analyzed the data and wrote the manuscript. Sci. Semantic Scholar uses AI to extract papers important to this topic. Beginning in F10, individuals that showed signs of disease were quantified to obtain disease prevalence of colonies and masses. For annual analyses, the three monitoring events completed during that calendar year were used; the TSI12 event was included in 2012 for a fourth event for that year. Staghorn corals, as well as all other corals, need very oxygenated water containing adequate supplies of small planktonic animals. Ecol. In the best-case scenario, we would have expected to see a shift from fragment to colonies and eventually to masses across the study. doi: 10.7717/peerj.2711, Miller, M.

In addition, it was most common for plots to decrease in live cover and simultaneously increase in dead skeleton, indicating high mortality and not extreme movement that could support the notion that the population is just shifting spatially. 116012).Upper to mid reef slopes, lagoons with clear water (Ref. 434-438. The term is used in the 1994 IUCN Red List of Threatened Animals to refer collectively to species categorized as Endangered (E), Vulnerable (V), Rare (R), Indeterminate (I), or Insufficiently Known (K) and in the 1996 IUCN Red List of Threatened Animals to refer collectively to species categorized as Critically Endangered (CR), Endangered (EN), or Vulnerable (VU). Condition characteristics and a species census were completed in all plots. Number of days between monitoring events in which the wind speed was greater than the average wind speed (12.78 kts) observed in southeast Florida for the six tropical storms occurring during the study. Aronson, R. B., Bruckner, A. W., Moore, J., Precht, W. F., and Weil, E. (2008). Propagation through fragmentation has the potential to support the existence of this species in low levels but gains do not keep up with the mortality observed. Percent cover of living decreased for both patches during the study, although only BCA had a significant, decreasing linear trend [r2 = 0.5013, F(3,20) = 6.702, p < 0.001; Scooter: r2 = 0.07924, F(3,20) = 0.5738, p > 0.05; Figure 1). Branches can be over 1 m long and are slender, and colonies are usually loosely packed or ‘open’. doi: 10.1046/j.1462-2920.2003.00424.x, Vargas-Ángel, B., Thomas, J. D., and Hoke, S. M. (2003).

On the other hand, signs of recovery were present in this study in 2013 when predation and disease prevalence were minimal, maximum water temperatures were lower, and there were only a few days of elevated winds. Sci. Boxes represent the 25 and 75% quartiles with whiskers extending 1.5 ∗ interquartile range, the line represents the median, and dots are considered outliers. Differences were found between the annual means of fragment counts, with 2010, 2015, and 2016 as high years at Scooter and 2012 and 2016 at BCA. Simple linear regressions were used to analyze the annual trend observed in PCL. Some of the species that live in the corals have already yeilded compounds active against inflammations, asthma, leukemia, tumors, heart disease, fungal and bacteria infections, and even viruses including HIV (Chadwick 1999). Tropical storm metadata for southeast Florida including days impacted (based on elevated wind levels), monthly average wind speed, rainfall, and wave height (calculated using the Beaufort Scale) for the month the storm occurred, overall mean sustained wind, rainfall and wave height across impact days, maximum daily average wind and wave height, maximum speed of wind gusts, rainfall, and wave height, and the decrease in in situ water temperatures during and following the storm and the duration of the change. Boxes represent the 25 and 75% quartiles with whiskers extending 1.5 ∗ interquartile range, the line represents the median, and dots are considered outliers. Sci. The occurrence of white disease, fireworm predation, snail predation, and bleaching were summed by their occurrence on colonies or masses per plot. Staghorn corals are also of vital importance to the stabilization of coastlines, as fish habitats, and for the protection of our biodiversity (Nemoto 1992). Acropora cervicornis grows into cylindrical branches with a large corallite at the tip of each branch. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. Overall mean prevalence of disease was higher on masses 36 ± 2.5 and 41 ± 1.9% than on colonies 8 ± 0.8 and 7 ± 0.5% for BCA (X2 = 37.525, p < 0.001) and Scooter (X2 = 88.801, p < 0.001), respectively. Bleaching was not present during all events and was significantly higher during the fall for BCA (Tukey, p < 0.001) and summer for Scooter (Tukey, p < 0.01). Acropora cervicornis like to live in warm, marine water close to the surface. Coral Reef Conserv. New York: Franklin Watts. Microsoft. Gladfelter, W. (1982). Prog. Since its population declines due to a wide spread disease event in the early 1980s, limited long-term monitoring studies describing the impact of current threats and potential recovery have been completed. When present, it was recorded as the primary cause of mortality in 30 ± 5 and 41 ± 4% plots on average for BCA and Scooter, respectively. Plots in which A. cervicornis were never recorded during the duration of the study were not included in the analysis (n = 5 for BCA). The editor and reviewers' affiliations are the latest provided on their Loop research profiles and may not reflect their situation at the time of review. Of concern is the relationship between disease and predation prevalence and occurrences on masses, which is implying density driven mortality and indicating a cyclical component to the existence of the species. 119, No. No seasonal trends were detected in the prevalence of damselfish predation. A window to the past: documenting the status of one of the last remaining ‘megapopulations’ of the threatened staghorn coral Acropora cervicornis in the Dominican Republic. Live tissue at BCA at this time also decreased but only slightly (-20 m2), and the prevalence of disease and predation were elevated but lower than Scooter. 6: 780-793. Above average air temperatures from May through mid-October 2009 caused SST to remain high through October, resulting in over 80 days at or above 30°C. Articles. Sci. Because the alga need light for photosynthesis, they play an important role in where a coral can live. The greatest PCL losses occurred following system-wide disturbance events such as tropical storms, hurricanes, or disease events (Table 1 and Figure 2). Table 2. It is also likely that fireworms and snails may be acting as vectors or reservoirs for pathogens as there is a relationship between the prevalence of disease and predation at both sites (Williams and Miller, 2005; Gignoux-Wolfsohn et al., 2012; Miller et al., 2014b; Bright et al., 2015). The very first stage of reproduction is a sexually-caused stage of reef-building. doi: 10.7717/peerj.4433. Percent live cover of Acropora cervicornis per plot for BCA (blue) and Scooter (red) across monitoring periods (A,D), annually (B,E), and seasonally (C,F). 846), subtidal reef tops and reef edges (Ref. Increased occurrence and prevalence of fireworm and snail predation toward the end of the study could be severely damaging for the future growth of the species because predation may become more focused due to the lack of tissue available, leading to the removal of more growth tips from the same colonies. 87209).Hermaphroditic (Ref. Species composition and zonation. Sisson, .. June 1973. Our data indicate that the diseases affecting A. cervicornis, while continuously observed in background levels, may also be exacerbated by increased water temperatures and disturbance events. Ecol. Mar. The present work aims to address that gap by monitoring two types of epigenetic mechanisms, namely histone modifications and DNA methylation, during a 7‐week‐long experiment in which staghorn coral fragments (Acropora cervicornis) were exposed to nutrient stress (nitrogen, nitrogen + phosphorus) in the presence of thermal stress. PeerJ 4:e2523. "National Geographic" (On-line). Small-scale mapping of indeterminate arborescent acroporid coral (Acropora cervicornis) patches.

(2013-01) Artikeln kan eventuellt innehålla språkliga fel eller ett märkligt bildurval. Prevalence of plots with fireworm predation was lower at BCA, affecting fewer than 70% of the plots during any monitoring event. Frequent disturbances such as tropical storms, hurricanes, and disease events, caused increased, prolonged, and widespread mortality. Trends in mean percent cover of living (PCL) A. cervicornis were analyzed using Time Series Analyses followed by decomposing the components and analyzing the decomposed trend component with a linear regression (R Core Team, 2017).
