The ecophysiology of the cold-water coral Lophelia pertusa (Scleractinia)
… to allow comparisons with another<br/>cold-water scleractinian. Caryophyllia smithii was able to maintain respiratory<br/>independence throughout a range of PO2 and displayed a degree of regulation similar to L. pertusa. Q10 values suggest that C. smithii may be physiologically affected at high …

Comportamento reprodutivo de Mussismilia hispida (Verril, 1902) (Cnidaria, Anthozoa, Scleractinia)
Through histological analysis the reproductive pattern of Mussismilia hispida, a zooxanthellate coral species endemic to the Brazilian coast was verified. Fragments from 2 tagged colonies, which were marked in the field in order to be repeatedly sampled, and 10 others haphazardly chosen were …

Aspectos morfológicos e microanatômicos das espécies brasileiras de Mussidae Ortmann, 1890 (Cnidaria, Scleractinia)
In the purpose of extend the character used in Scleractinian systematic, it was done a descriptive study of different aspects of the polyp microanatomy and cnidom of four species of Mussidae. Three species belonging to the Brazilian genus Mussismilia: M. hispida (Verrill, 1868), M. braziliensis …

Identificação dos coralitos de pólipos fundadores de corais recifais do Brasil (Cnidaria, Anthozoa, Scleractinia)
To study an organism's life history, it is important to identify them throughout their life cycle. ln corals, a complicating factor is the difficulty of identification at their initial stages. The taxonomy of corais is based on skeletal structures present in the adults. The purpose of this study …

Variação morfológica dos esqueletos de Montastraea cavernosa (Linnaeus, 1767) e Favia gravida Vernill, 1868 (Cnidaria, Scleractinia)
Morphological variability is a widespread but poorly understood characteristic of many colonial animals. Skeletal variations of Montastraea cavernosa from Brazil, Abrolhos (BA), Tamandaré (PE) and Mexico, Puerto Morelos (Q.ROO) and variations of Favia gravida from Brazil, Abrolhos, Tamandaré and …

Variação de formas de crescimento de Montastraea cavernosa (Linnaeus, 1767) (Cnidaria, Anthozoa, Scleractinia): uma abordagem modular
Clonal animals grow through addition of functional units (zooids), whose assemblage constitutes a colony. The modular approach consists in describing colony form from the arrangement and size of modules. The modular approach was used here to access variations in growth forms of the coral …

Esforço reprodutivo de Mussismilia braziliensis (Verrill, 1868) (Cnidaria, Scleractinia, Mussidae) no complexo recifal dos Abrolhos, BA, Brasil
Mussismilia braziliensis is endemic to Bahia State. lt plays an important role as one of the major reef builders in the area. Ten fragments of colonies were collected at three sites in the Abrolhos Reef Complex, located at different distances from the coast. Reproductive effort was estimated …

Comunidades recifais do Arquipélago dos Abrolhos, BA, com ênfase em corais (Cnidaria: Scleractinia e Milleporidae): aspectos metodológicos e comparações entre locais
The quantification of coral communities in three areas in the Abrolhos Archipelago (northern and southern inshore areas in Santa Bárbara Island, and Siriba Island) was performed using quadrats and intercept line transect methods. Colony size and inclination, the distances from random points to the …

Distribution and community structure of Chaetodontidae (Perciformes) in iSimangaliso Wetland Park with the view to applying the Butterflyfish Indicator Hypothesis in this region of South Africa
… low abundances of its preferred coral Acropora (Scleractinia: Acroporidae), suggest that the BIH is not useful in this region.

Flow injection analysis (FIA) determination of lead by hydride generation in banded coral skeletons /
A flow injection hydride generation direct current plasma atomic emission spectrometric (FI-HG-DCP-AES) method was developed for the determination of lead at ng.ml-l level. Potassium ferricyanide (K3Fe(CN)6) was used along with sodium tetrahydroborate(III) (NaBH4) to produce plumbane (PbH4) in an …

Evolutionary patterns within the Anthozoa (phylum Cindaria) reflected in ribosomal gene sequences
… and its species are closely related to the Order Scleractinia. Dactylanthus, also within the Hexacorallia, is allied with the anemones in the Order Actiniaria, and their current ordinal-level designation does not appear to be justified. The genus Dendrobrachia, originally classified within the …

In Hot Water: Thermal Acclimation is Insufficient to Save Corals in the Anthropocene
<p>Scleractinian corals are animal partners in exquisite symbioses with a suite of algal, microbial, fungal and viral associates comprising miniature ecosystems collectively referred to as a holobiont. In recent decades, ocean warming has jeopardized the delicate balance of the very symbioses that …

Population Genetic Structure of the Temperate Scleractinian Coral, Oculina Arbuscula, in Coastal Georgia
Dispersal of marine organisms has generally been assumed to be demographically open with planktonic larvae exploiting ocean currents to travel long distances. However, recent studies report evidence of local larval recruitment. In this study, I hypothesized that populations of the temperate coral, …
