Abstract:
The evolutionary history of scleractinian corals, based on morphological taxonomy and inferences from the fossil record, has been poorly understood. Molecular techniques developed over the past ten years are now being used to gain a new perspective on scleractinian phylogeny. DNA sequences, mitochondrial genome structure, and morphological characters support a basal position for the Anthozoa in the phylum Cnidaria. Mitochondrial and nuclear DNA sequences suggest a relatively derived position of the order Scleractinia within the class Anthozoa. Mitochondrial and nuclear DNA sequences have provided a new hypothesis for evolution within the Scleractinia that is different from hypotheses based on morphological characters of extant and fossil taxa. Groupings within the two major lineages defined by molecular data do not correspond to morphological suborder groupings although groupings of genera within families do correspond to traditional taxonomy. This new molecular hypothesis suggests that the Scleractinia are represented by two major lineages that diverged from each other before the appearance of the scleractinian skeleton in the fossil record. This divergence time supports the hypotheses that the Scleractinia are not related to the Rugosa of the Paleozoic and that the scleractinian skeleton has evolved more than once. These two major lineages may represent two architectural strategies within the Scleractinia that have led to their great morphological diversity.

Abstract:
Abstract The Scleractinia, which are one of the most important builders of modern reefs, have been considered to have first appeared in the Middle Triassic. Recently, Paleozoic scleractiniamorphs have been reported from both the Ordovician and the Permian, suggesting that the scleractinian-like body plan was already established in the Paleozoic. Those Paleozoic scleractiniamorphs are considered either unsuccessful skeletonized offshoots (extinct experiments) or Paleozoic progenitors of the post-Paleozoic Scleractinia. Permian scleractiniamorphs are characterized by “ancestral” features and have no specific morphologies that deny scleractinian affinities. Molecular phylogenetics also indicate that extant scleractinians are monophyletic and originated long before their Triassic appearance. A Paleozoic origin for the Scleractinia is supported by morphological and molecular phylogenetic data. On the other hand, there is no positive evidence to show that different groups of scleractinians had separate soft-bodied precursors. The Paleozoic scleractinians evolved within the framework of their basic body plan, and a direct derivation of the Scleractinia from the Rugosa is not probable. The Anthozoa are characterized by a bilaterally symmetrical body plan, which is traditionally considered to have been derived from other radially symmetrical Cnidaria. The problem of the origin of scleractinian body plan may provide a key for deciphering the early anthozoan radiation within the Bilateria. Other examples of Paleozoic Scleractinia and scleractiniamorphs will be found, probably in shallow-water reefal facies or deeper-water communities, bridging the stratigraphic gaps in occurrence and elucidating the origin of the Scleractinia and their body plan.

Abstract:
Gathering and studying a rich collection of fossil corals in Bulgaria led to the definition of various new taxa, but highlighted the gaps in our knowledge of fossil Scleractinia. I needed to learn from living corals. An actuopaleontological project with massive sampling of all phenotypes following coral life in depth in Cuba (1970–1973) showed extraordinary scleractinian variability and led to “heresy” regarding the conventional Caribbean taxonomy. Subsequent fundamental new knowledge challenged Scleractinia taxonomy and justified the results of the investigation of the Cuban corals, through continuing contributions to: holistic approach to scleractinian species; integrative character of coral taxonomy; new paleobiological perspectives and tasks for study; and the evolutionary benefits of hybridization for reef survival. Continuing research can be supported by: an 80% preserved collection; a scientific audiovisual documentary; a monograph in Russian, French, and soon Spanish; and a substantially and rarely preserved coral life and reef ecosystem.

Abstract:
The coral reefs of Utila and Cayos Cochinos located in the western Caribbean region (Honduras) were studied in Summer 2010 in order to acquire information concerning their richness in stony corals (Scleractinia, Milleporidae, and Stylasteridae) down to 18 m depth. Ten sites in each location were visually surveyed. Fourty-six species and 12 forms of zooxanthellate scleractinian corals belonging to 21 genera were observed at Utila and 44 species and 12 forms belonging to 20 genera at Cayos Cochinos. At each site, 3 species of milleporids and one species of Stylaster (S. roseus) were also observed. Four forms of zooxanthellate scleractinian corals were new records from Honduras. Up to now, 53 species of scleractinian corals have been identified within the whole Honduran Caribbean coast. They belong to 24 genera. This number represents approximately 93% of all scleractinian coral species reported for the Caribbean.

Abstract:
Over the past few decades, modern coral taxonomy, combining morphology and molecular sequence data, has resolved many long-standing questions about scleractinian corals. In this study, we sequenced the complete mitochondrial genomes of three Merulinidae corals (Dipsastraea rotumana, Favites pentagona, and Hydnophora exesa) for the first time using next-generation sequencing. The obtained mitogenome sequences ranged from 16,466 bp (D. rotumana) to 18,006 bp (F. pentagona) in length, and included 13 unique protein-coding genes (PCGs), two transfer RNA genes, and two ribosomal RNA genes . Gene arrangement, nucleotide composition, and nucleotide bias of the three Merulinidae corals were canonically identical to each other and consistent with other scleractinian corals. We performed a Bayesian phylogenetic reconstruction based on 13 protein-coding sequences of 86 Scleractinia species. The results showed that the family Merulinidae was conventionally nested within the robust branch, with H. exesa clustered closely with F. pentagona and D. rotumana clustered closely with Favites abdita. This study provides novel insight into the phylogenetics of species within the family Merulinidae and the evolutionary relationships among different Scleractinia genera.

Abstract:
The focus of this paper is to provide an overview of historical and modern accounts of scleractinian evolutionary relationships and classification. Scleractinian evolutionary relationships proposed in the 19th and the beginning of the 20th centuries were based mainly on skeletal data. More in-depth observations of the coral skeleton showed that the gross-morphology could be highly confusing. Profound differences in microstructural and microarchitectural characters of e.g., Mesozoic microsolenine, pachythecaliine, stylophylline, stylinine, and rhipidogyrine corals compared with nominotypic representatives of higher-rank units in which they were classified suggest their separate (?subordinal) taxonomic status. Recent application of molecular techniques resulted in hypotheses of evolutionary relationships that differed from traditional ones. The emergence of new and promising research methods such as highresolution morphometrics, analysis of biochemical skeletal data, and refined microstructural observations may still increase resolution of the “skeletal” approach. Achieving a more reliable and comprehensive scheme of evolutionary relationships and classification framework for the Scleractinia will require close cooperation between coral biologists, ecologists, geologists, geochemists, and paleontologists.

Abstract:
INTRODUZIONE GENERALE Le comunità di coralli di acqua fredda sono estremamente importanti per l'ecosistema bentonico. Essendo stato dichiarato un importante ecosistema sia per il valore ecologico che per quello economico, la proposta di questa tesi è quella di descrivere le comunità di coralli d'acqua fredda nell'Adriatico sud. Le attività di ricerca si sono concentrate su quattro diversi argomenti elencati di seguito. La fauna bentonica di Sessile associata al corallo sub-fossile dell'acqua fredda dall'Albania Questo studio presenta una descrizione preliminare della fauna associata al quadro corallo subfossile in due siti recentemente trovati in Albania. La Macrofauna è stata registrata durante due indagini di pesca sperimentali condotte nel marzo 2015 e nel maggio 2016 in due zone profonde della costa albanese, tra la profondità di 190 e 230 m. Sono stati analizzati campioni di coralli subfossili di Lophelia pertusa e Dendrophyllia cornigera per identificare la fauna associata. Sono state identificate 82 specie, 2 Foraminifera, 22 Porifera, 6 Cnidaria, 25 Mollusca, 14 Annelida, 1 Arthropoda, 11 Bryozoa, 1 Echinodermata, di cui 75 specie che sono nuovi record per la fauna albanese. Tutte le specie identificate sono state precedentemente riportate nelle aree coralline di Santa Maria di Leuca e Bari Canyon. Questo studio ha aggiornato la conoscenza della biodiversità del profondo mare Adriatico sudorientale, nonché della fauna marina albanese in particolare. Nuove informazioni ottenute per le specie di acque profonde confermano l'importante contributo del quadro di corallo dell'acqua fredda nella biodiversità del segnale acustico. Variazioni morfologiche spatiotemporali del Mediterraneo Lophelia pertusa. Per valutare se la variazione morfologica di L. pertusa segue un modello specifico basato su variabili ambientali (o altre), questo studio combina due differenti approcci morfometrici: la morfologia lineare lineare classica e l'utilizzo di punti di riferimento delle coordinate tridimensionali (landmarks). Gli obiettivi principali di questo studio sono quello di verificare l'esistenza di gruppi morfologici distinti all'interno della specie cosmopolita L. pertusa nel Mediterraneo e di individuare eventuali relazioni tra gruppi morfologici (sia nei coralli moderni che nei coralli fossili) e (paleo) delle condizioni oceanografiche. Applicazioni della tomografia computazionale a raggi X nello studio della morfologia della L. Pertusa. Lo scopo di questo lavoro è stato quello di confrontare 4 colonie di Lophelia pertusa corallo sub-fossile, provenienti dal Mediterraneo e dall'Atlantico orientale. I sottogruppi sono riferimenti importanti che testimoniano le condizioni ambientali del paleo-ambientale, pertanto il loro studio morfologico è un tema importante per l'ecologia. Lo scopo di questo è stato quello di indagare se esistono differenze veramente morfologiche tra queste quattro colonie Lophelia, sia nella morfologia dei coralli e nella loro organizzazione spaziale. La tomografia computerizzata dei campioni ci ha permesso di misurare alcune variabili scelte secondo le caratteristiche della specie. Datazione la morte dei coralli sclerattiniani profondi del mare sud-orientale Questa parte del mio studio riguarda la precisa datazione U / T di coralli morti provenienti provenienti da acque albanesi. Gli Smples furono ottenuti dall'Albania dalla crociera oceanografica CNR CoCoMap13 nel Mare Adriatico del sud-est e da una Lophelia pertusa colonia catturata durante le indagini di pesca sperimentali a nord della baia di Vlora. Lo scopo è di datare la presenza di CWC nelle acque profonde albanesi, valutando anche il tempo per l'insediamento e la scomparsa del CWC nel AdriATICO
The present study regarding the Albanian CWC and associated biota consists of specific research activities focused on the four main topics listed below. Sessile benthic fauna associated with sub-fossil Cold Water Coral from off Albania This section presents a preliminary description of the fauna associated with sub-fossil coral framework in two sites recently found in off Albania. Macrofauna was recorded during two experimental fishing surveys conducted in March 2015 and May 2016 in two deep areas of the Albanian coast, between the depth of 190 to 230 m. Sub-fossil coral samples of L. pertusa and D. cornigera were analyzed to identify the associated fauna. A total of 82 species were identified, 2 Foraminifera, 22 Porifera, 6 Cnidaria, 25 Mollusca, 14 Annelida, 1 Arthropoda, 11 Bryozoa, 1 Echinodermata, including 75 species that are new records for the Albanian fauna. Morphological variations of Mediterranean Lophelia pertusa The main aims of this study are to test the existence of distinct morphological groups within the quasi-cosmopolitan species L. pertusa in the Mediterranean and to identify, if any, relationships between morphological groups (both in modern and fossil corals) and (paleo) oceanographic conditions. Applications of X-ray Computed Tomography in the morphometric study of the Adriatic Lophelia pertusa The aim of this analysis was to investigate whether there are really morphological differences between these four Lophelia colonies, both in the morphology of the corallites and in their spatial organization. Computed tomography made possible to measure some variables chosen according to the species's characteristics. Dating the Albanian Adriatic cold water corals This part of my study deals on the the precise U/Th dating of dead corals specimens sourced coming from Albanian waters. Smples were obtained off Albania by the oceanographic CNR CoCoMap13 cruise in the southeastern Adriatic Sea and one Lophelia pertusa colony caught during experimental fishing surveys in north of the Vlora Bay. The purpose is to time in the presence of CWC in Albanian deep waters, assessing also the tempo for CWC settlement and demise in the southern Adriatic Sea.

Atualmente, o aumento da sedimentação e do aporte de matéria orgânica são apontados como principais agentes causadores da devastação dos recifes de corais. Portanto este trabalho teve como objetivo investigar, em laboratório, os efeitos do aumento da sedimentação, associada ou não com matéria orgânica, sobre a fotossíntese, avaliada a partir da eficiência fotobiológica das zooxantelas associadas, e o estado físico do tecido, avaliado a partir de um índice quantitativo de susceptibilidade, de Mussismilia braziliensis, uma espécie de coral endêmico da Bahia e principal construtor do maior complexo recifal do Atlântico Sul. A susceptibilidade das colônias expostas ao sedimento sem matéria orgânica foi comparada com a susceptibilidade das colônias expostas ao sedimento com matéria orgânica. Os resultados encontrados possibilitaram a comparação com ecossistemas recifais mais estudados e também serão úteis para o manejo dos recifes contra impactos humanos. Os experimentos foram conduzidos em aquários do laboratório de Recifes de Corais e Mudanças Globais (RECOR). Para isso foram coletadas 19 colônias de M. braziliensis em um recife do arco costeiro de Abrolhos e sedimento lamoso no canal do rio Caravelas. No laboratório o sedimento foi preparado (lavado e secado) e separado em dois tratamentos, sendo um formado por sedimento com matéria orgânica e outro com sedimento sem matéria orgânica. O sistema experimental consistiu de 19 cubas de vidro de 4 litros, contendo água salina sintética a 36 psu, acondicionadas em aquários de 60 litros, com água doce circulante a 26°C, iluminados durante 12 horas diárias. Em cada cuba foi colocada uma colônia de M. braziliensis. Em sete cubas foram adicionadas concentrações de sedimento livre de matéria orgânica, equivalentes a 0, 15, 50, 150, 250, 350 e 450 mg.cm-2.dia-1. Nas 12 cubas restantes foram adicionadas concentrações de sedimento combinado com matéria orgânica equivalentes a 0, 15, 50, 100, 150, 200, 250, 300, 350, 400, 450 e 500 mg.cm-2.dia-1. Diariamente a água das cubas foi agitada por dois minutos para simular eventos de ressuspensão e deposição de sedimento. Para as colônias expostas ao sedimento sem matéria orgânica foi realizada uma análise de regressão linear simples entre a taxa de sedimentação e a susceptibilidade física das colônias, avaliada após 45 dias de exposição, a partir de um índice quantitativo de susceptibilidade à sedimentação. Para as colônias expostas ao sedimento associado com matéria orgânica, foram realizadas duas análises de regressão linear simples relacionando a taxa de sedimentação com a eficiência fotoquímica, estimada a partir do fluorômetro Diving-PAM, após 72 horas de exposição, e com o índice de susceptibilidade, após 120 horas de exposição. Após 120 horas de exposição foi comparada, através de um teste de Mann-Whitney, a susceptibilidade das colônias expostas ao sedimento sem matéria orgânica com a susceptibilidade de colônias expostas ao sedimento associado com matéria orgânica. Os testes de regressão mostraram uma relação positiva significativa entre a taxa de sedimentação e o índice de susceptibilidade das colônias de M. braziliensis expostas ao sedimento com e sem matéria orgânica associada. Para os dois conjuntos de colônias, entretanto, danos físicos severos foram encontrados apenas em colônias expostas a taxas superiores a 200 mg.cm-2.dia-1, que visaram simular impactos extremos como tempestades e dragagens. Diferente do esperado, o aumento da sedimentação não provocou a redução da eficiência fotobiológica das colônias expostas ao sedimento combinado com matéria orgânica. Os resultados encontrados são indicativos de tolerância à sedimentação e também da capacidade de fotoaclimatação dos corais de águas brasileiras, submetidos naturalmente a ambientes turvos. As colônias expostas ao sedimento associado com matéria orgânica apresentaram uma maior susceptibilidade à sedimentação, um resultado preocupante tendo em vista o aumento atual da poluição marinha como consequência do desenvolvimento costeiro e do mau uso da terra.
The increase in sedimentation and organic matter are pointed out as the major agents responsible for impacting corals around the world. In Brazil, where reefs generally occur in markedly turbid environments and productive, the direct effects of sediment and organic matter elevation are poorly known. Thus, in a laboratory experiment, the effect of sedimentation associated with or free of organic matter over photosynthesis and tissue physical state of Mussismilia braziliensis were compared. Seven colonies of M. braziliensis were exposed to a sedimentation gradient (0 to 450 mg.cm-2 .day-1 ) free of organic matter. After 45 days of exposure, the physical health of corals was estimated, evaluated on the basis of a susceptibility index of sedimentation, developed in this work. Twelve colonies of M. braziliensis were exposed to a gradient of sedimentation (0 to 500 mg.cm-2.day- 1) with approximately 10% organic matter. After 72 hours dark adapted maximum photochemical efficiency was measured using a Diving-PAM (Walz, Germany) fluorometer, and after 120 hours, coral tissue state based on the susceptibility was evaluated. The comparison of the susceptibility index of colonies submitted to sediment with organic matter with the index of the colonies submitted to sediment free of organic matter resulted in a significant and positive relationship with sedimentation rate. However, no significant effect of sedimentation and organic matter was observed on photochemical efficiency of M. braziliensis zooxanthellae. This study showed that the Brazilian coral M. braziliensis is tolerant to sedimentation, and capable of producing energy via photosynthesis even in environments impacted by intense sedimentation and increasing organic matter. On the other hand, these results suggest that the increase of sedimentation interfere negatively in M. braziliensis tissue health and represents a greater menace to corals when sediment is associated with organic matter.

Abstract:
Uma das espécies de coral pétreo zooxantelado com mais ampla distribuição no litoral brasileiro é Madracis decactis Lyman, 1859. M. decactis forma colônias incrustantes nodulares que podem atingir até 30 cm de diâmetro. O estudo da gametogênese foi realizado através de coletas bimensais na Baía de Ilha Grande, RJ durante 21 meses (agosto/2004-maio/2006), totalizando 10 coletas (12 colônias/coleta) (Licença IBAMA no. 201/2004). Foram realizados cortes histológicos de 7 µm, e de 10 até 16 pólipos por colônia foram analisados, totalizando mais de 1800 pólipos. A análise dos pólipos indicou que M. decactis é hermafrodita, com gametas localizados no mesmo lóculo gástrico, porém em mesentérios diferentes. A gametogênese durou cerca de sete meses. A ovogênese iniciou-se ao redor de outubro, enquanto que a espermatogênese teve inicio no final de fevereiro, ambas terminando em sincronia no final do mês de maio. O exame dos pólipos férteis indicou a presença dos estágios I, II e III de desenvolvimento para a ovogênese e dos estágios I, II, III e IV para a espermatogênese. Não foram encontrados embriões ou plânulas nos cortes histológicos, indicando talvez que estes estágios permaneçam pouco tempo no interior do pólipo. O pico da atividade reprodutiva ocorre entre os meses de fevereiro e abril com todas as colônias férteis contendo ovócitos principalmente no estágio III de maturação. A provável época de liberação de plânulas ocorre entre os meses de abril e maio, sob influencia das condições ambientais como a temperatura da água do mar, a irradiação solar e a pluviosidade. O presente trabalho forneceu informações básicas a respeito da biologia reprodutiva de Madracis decactis presente em Ilha Grande, sendo uma contribuição para outros estudos mais específicos na área de manejo e conservação de ambientes marinhos.
One of the most wide distributed coral species along the Brazilian cost is Madracis decactis Lyman, 1859. M. decactis growths as nodular incrusting colonies that can reach up to 30 cm in diameter. In order to study the gametogenesis cycle, bimonthly collections were done at Ilha Grande Bay, Rio de Janeiro, during 21 months (August/2004- May/2006), totaling 10 collections (12 colonies/collection) (License no. 201/2004). Histological sections of 7 µm thick were done to analyze 10 to 16 polyps per colony (more than 1800 polyps in total). The analysis indicated that M. decactis is hermaphroditic, with male and female gametes developing at the same gastric loculi, but in different mesenteries. The gametogenesis lasted about 7 months, the oogenesis starts at October , while spermtogenesis starts at the end of February, both reaching the maturity in synchrony at the end of May. The exam of fertile polyps indicated the presence of stages I, II and III for oogenesis and I, II, III and IV for spermatogenesis. No embryo or planula were observed in the histological sections, indicating that maybe these stages stay for a short period inside the polyp cavity. The peak of reproductive activity was between February and April when all the polyps were fertile containing manly stage III oocytes. The releasing of planulae may happen between April and May, under the influence of environmental conditions as sea water temperature, solar insolation and rainy season. The present study has provided basic information about the reproductive biology of Madracis decactis from Ilha Grande Bay, and it may be a contribution to further studies about management and conservation of marine environments.

Abstract:
Geometric morphometrics are a useful tool for studying morphological variation in scleractinian corals, extant and extinct. In the case of modern specimens, three-dimensional features of the calical surface can be measured. These features are rarely preserved in fossil corals, however, necessitating measurement of 2-D landmarks in transverse thin-sections of corallites. Unfortunately, 2-D and 3-D methods often yield differing answers to questions about interspecific, intraspecific and intracolonial variation. This issue is addressed in the present study by directly comparing results of 2-D and 3-D geometric morphometric analyses of identical colonies of extant members of the Montastraea "annularis" species complex. Ten colonies of each extant species in the complex (M. annularis s.s., M. faveolata and M. franksi), identified in the field during collection and verified by molecular data, were selected for analysis. Slabs of colony surfaces and transverse thin-sections from ~1 cm below the surface were cut from tops and edges of each colony. Six corallites from each slab were measured in 3-D using a Reflex microscope, and six measured in 2-D on digital images of each transverse thin-section. Both datasets were explored using geometric morphometric methods and analyzed statistically to address questions related to measurement error, intracolonial variation in corallite morphology between tops and edges of colonies, and interspecific morphological differences. The shape data were superimposed using Procrustes generalized least squares, and examined using principal components and canonical variates analyses. Shape differences implied by axes obtained from PCA and CVA were depicted as deformations using the thin-plate spline, to identify which morphological features are correlated with axes of greatest total variance (PCA) and greatest between-group variance (CVA). Goodall's F-test was used to detect significant morphological differences among species and colony positions. All of the data used in these analyses are available in the supplementary file that accompanies this thesis (see Appendix C for a description of the contents of this file). Measurement error analyses show significant differences among variances associated with replicate measurements of 2-D and 3-D landmarks. In many cases the variance is asymmetrical, and for 2D data especially, this asymmetry coincides with orientation of anatomical features. Significant shape differences between corallites from tops and edges of colonies of M. annularis and M. faveolata are found when 3-D data are used. These intracolonial differences are due in large part to height and shape of the septal margin. As a result, 2-D data are unable to find significant differences within colonies. Both datasets find significant interspecific differences, but different anatomical features are found to be responsible. Important interspecific differences for 2-D data are relative thickness of the corallite wall and lengths of septa and costae. When 3-D data are used, results are most influenced by height of primary and secondary septa above the calical surface, as well as length of septa from the corallite wall toward the columella. Patterns of relative morphological similarity among species also differ between datasets. 2-D data show closest similarity between M. annularis and M. faveolata, while M. faveolata and M. franksi are most similar when 3-D data are used. The former result is consistent with previous 2-D analyses, while the latter conclusion is without precedent. Neither is consistent with relationships inferred using molecular data.

Abstract:
This study investigates effects of eutrophication on settlement, abundance, mortality and community structure of soleractinian corals on fringing reefs on the west coast of Barbados, W.I. Juvenile abundance was lower, but juvenile size larger, on eutrophic than less eutrophic reefs. The lower abundance results at least in part from a higher juvenile mortality on eutrophic reefs. Algae were more abundant and grazers (Diadema antillarum and herbivorous fish) less abundant on eutrophic reefs. Juvenile community structure on all reefs, and adult community structure on eutrophic reefs, was dominated by type 1 corals (high recruitment, high natural mortality). Type 2 corals (low recruitment, low natural mortality) were common in adult communities on less eutrophic reefs. Settlement of coral recruits on artificial substrates was lower on more eutrophic reefs.
