“…Although sexual reproduction might also occur in Tubastraea , the results obtained for T. coccinea might be an effect of the occurrence of recent multiple introductions from different native populations (Roman & Darling, 2007). Another hypothesis would be the presence of cryptic species, which has been found in other scleractinian corals (Pinzón & Weil, 2011; Warner, Van Oppen & Willis, 2015; Nakajima et al, 2017). Morphological analyses combined with molecular data including native populations are necessary to corroborate this hypothesis.…”

Although the invasive azooxanthellate corals Tubastraea coccinea and T. tagusensis are spreading quickly and outcompeting native species in the Atlantic Ocean, there is little information regarding the genetic structure and path of introduction for these species. Here we present the first data on genetic diversity and clonal structure from these two species using a new set of microsatellite markers. High proportions of clones were observed, indicating that asexual reproduction has a major role in the local population dynamics and, therefore, represents one of the main reasons for the invasion success. Although no significant population structure was found, results suggest the occurrence of multiple invasions for T. coccinea and also that both species are being transported along the coast by vectors such as oil platforms and monobouys, spreading these invasive species. In addition to the description of novel microsatellite markers, this study sheds new light into the invasive process of Tubastraea.

“…Phenotypic plasticity is rampant in the clades under investigation (e.g. Foster, 1979; Tomascik, 1990; Van Veghel & Bak, 1993; Todd et al ., 2004; Todd, 2008; Pinzón & Weil, 2011; Hoeksema, 2012); therefore, deleting characters that reveal little or no congruence with molecular results was an important step in reducing noise. The results show that when clades XIX and XXI alone are compared, the morphological tree agrees well with the molecular tree.…”

Molecular analyses are transforming our understanding of the evolution of scleractinian corals and conflict with traditional classification, which is based on skeletal morphology. A new classification system, which integrates molecular and morphological data, is essential for documenting patterns of biodiversity and establishing priorities for marine conservation, as well as providing the morphological characters needed for linking present‐day corals with fossil species. The present monograph is the first in a series whose goal is to develop such an integrated system. It addresses the taxonomic relationships of 55 Recent zooxanthellate genera (one new) in seven families (one new), which were previously assigned to the suborder Faviina (eight genera are transferred to incertae sedis). The present monograph has two objectives. First, we introduce the higher‐level classification system for the 46 genera whose relationships are clear. Second, we formally revise the taxonomy of those corals belonging to the newly discovered family‐level clade (restricted today to the western Atlantic and Caribbean regions); this revised family Mussidae consists of ten genera (one of which is new) and 26 species that were previously assigned to the ‘traditional’ families Faviidae and Mussidae. To guide in discovering morphologic characters diagnostic of higher‐level taxa, we mapped a total of 38 morphologic characters [19 macromorphology, eight micromorphology, 11 microstructure] onto a molecular tree consisting of 67 species [22 Indo‐Pacific and seven Atlantic species in the traditional family Faviidae; 13 Indo‐Pacific and ten Atlantic species in the traditional family Mussidae; 13 species in the traditional families Merulinidae (5), Pectiniidae (7), and Trachyphylliidae (1); two Atlantic species of traditional Montastraea], and trace character histories using parsimony. To evaluate the overall effectiveness of morphological data in phylogeny reconstruction, we performed morphology‐based phylogenetic analyses using 27 (80 states) of the 38 characters, and compared morphological trees with molecular trees. The results of the ancestral state reconstructions revealed extensive homoplasy in almost all morphological characters. Family‐ and subfamily‐level molecular clades [previously identified as XVII−XXI] are best distinguished on the basis of the shapes of septal teeth and corresponding microstructure. The newly revised family Mussidae (XXI) has septal teeth with regular pointed tips (a symplesiomorphy) and a stout blocky appearance. It has two subfamilies, Mussinae and Faviinae. The subfamily Mussinae is distinguished by spine‐shaped teeth and widely spaced costoseptal clusters of calcification centres. The subfamily Faviinae is distinguished by blocky, pointed tricorne or paddle‐shaped teeth with elliptical bases, transverse structures such as carinae that cross the septal plane, and well‐developed aligned granules. Defining diagnostic characters for the broader data set is more challenging. In analyses of taxonomic subsets of the dat...

“…These results could also suggest ecological differentiation, showing different patterns of distribution and specialization that might have been overlooked by using the information given by the coral species information alone. Since our field survey was done before the taxonomic revision of Meandrina (Pinzón and Weil, 2011), it is possible that these associations could correspond to the paler species M. jacksoni. The distribution of Symbiodinium spp.…”

Research on coral reef community structure suggests that fine spatial-temporal stochasticity drives biodiversity patterns in this tropical marine ecosystem. The combination of a coral colony and its zooxanthella, or holobiont, should therefore be used as the community indivisible units to better understand this structure. Research in zooxanthellae (Symbiodinium) diversity has allowed the identification of specific or generalist host associations. The distribution of specific symbionts depends on both the host identity and the environmental conditions. This study determined the identity on these symbionts within hard corals communities (Scleractinia and Milleporina) at 27 sites on the upper slope habitat (mixed zone) in Cartagena, Colombia (Southwestern Caribbean Sea). Zooxanthellae identification was made with RFLPs analysis (18S, SSU, rDNA), DGGE, and DNA sequencing (ITS2, rDNA). Different combinations of coral species and their specific Symbiodinium types (holobionts) were determined as different ecological units. Taking each holobiont as a variable, a cluster community structure analysis was made and compared to the pattern obtained from using coral species alone. Different site groupings occurred for holobionts and species, where higher similarities were found using holobionts. O. annularis and O. faveolata, two dominant coral species, formed independently different Symbiodinium associations, depending on depth. Their symbiont preference can be under higher selection pressure than previously thought, if they act as different ecological units. © Acad. Colomb. Cienc. Ex. Fis.

Conjuntos de holobiontes de especies dominantes de corales (Tipos de Symbiodinium y especies de corales) moldean la estructura comunitaria en arrecifes coralinos del Caribe ResumenInvestigaciones de la estructura de comunidades coralinas sugieren que escalas espacio temporales cortas son responsables de patrones en ecosistemas marinos tropicales. La combinación coral y su zooxantela, u holobionte, puede ser la entidad ecológica modificada por estos factores. La estructura de la comunidad de corales podría ser mejor entendida usando el holobionte como unidad indivisible de la comunidad. Investigaciones recientes en diversidad de zooxantelas (Symbiodinium spp.) han revelado asociaciones de tipo específicas, así como generalistas dependiendo del hospedero. Su distribución depende tanto del hospedero como de las condiciones ambientales. Este estudio determino la identidad molecular de estos simbiontes en comunidades de corales duros (Scleractinia y Milleporina) en 27 localidades en el talud arrecifal superior (zona mixta) en Cartagena, Colombia. La identificación de zooxantelas se realizó mediante análisis de RFLPs (18S, SSU, rDNA, por sus siglas en inglés), DGGE y secuenciación de ADN (ITS2, rDNA). Se encontró variación intra e intercolonial, dependiendo de la especie del hospedero. Se determinaron diferentes ho...
