MAR., 69 (1): 75-86 SCIENTIA MARINA 2005 Cnidae variability in Balanophyllia europaea and B. regia (Scleractinia: Dendrophylliidae) in the NE Atlantic and Mediterranean Sea* ALEJANDRO TERRÓN-SIGLER and PABLO J. LÓPEZ-GONZÁLEZ Biodiversidad y Ecología de Invertebrados Marinos, Departamento de Fisiología y Zoología, Facultad de Biología, Universidad de Sevilla, Reina Mercedes, 6, 41012 Sevilla, Spain. E-mail: [email protected] / [email protected] SUMMARY: Traditionally and for practical reasons, skeleton structure has been the main source of taxonomic characters for scleractinian systematics, whereas information from soft tissues has been comparatively neglected. However, skeleton variability may leave species identification uncertain. The use of characters from soft tissues (e.g. polyp anatomy, cnidae size) is routine in the study of other (“soft”) hexacorallian orders. This contribution aims to determine whether cnidae char- acters are useful in taxonomic studies of scleractinians. The cnidae composition of two congeneric species—Balanophyllia europaea (Risso, 1826) and Balanophyllia regia Gosse, 1860—have been studied throughout a wide geographical area. The data obtained show consistent qualitative and quantitative differences between the two species. This study shows that the cnidae characters can be useful taxonomic criteria for distinguishing congeneric species. Key words: Scleractinia, Balanophyllia, cnidome, taxonomy, geographical variability. RESUMEN: VARIABILIDAD EN LOS CNIDOCISTOS DE BALANOPHYLLIA EUROPAEA Y B.

Adaptive Divergence, Neutral Panmixia, and Algal Symbiont Population Structure in the Temperate Coral Astrangia Poculata Along the Mid-Atlantic United States
Adaptive divergence, neutral panmixia, and algal symbiont population structure in the temperate coral Astrangia poculata along the Mid-Atlantic United States Hannah E. Aichelman1,2 and Daniel J. Barshis2 1 Department of Biology, Boston University, Boston, MA, USA 2 Department of Biological Sciences, Old Dominion University, Norfolk, VA, USA ABSTRACT Astrangia poculata is a temperate scleractinian coral that exists in facultative symbiosis with the dinoflagellate alga Breviolum psygmophilum across a range spanning the Gulf of Mexico to Cape Cod, Massachusetts. Our previous work on metabolic thermal performance of Virginia (VA) and Rhode Island (RI) populations of A. poculata revealed physiological signatures of cold (RI) and warm (VA) adaptation of these populations to their respective local thermal environments. Here, we used whole-transcriptome sequencing (mRNA-Seq) to evaluate genetic differences and identify potential loci involved in the adaptive signature of VA and RI populations. Sequencing data from 40 A. poculata individuals, including 10 colonies from each population and symbiotic state (VA-white, VA-brown, RI-white, and RI-brown), yielded a total of 1,808 host-associated and 59 algal symbiont-associated single nucleotide polymorphisms (SNPs) post filtration. Fst outlier analysis identified 66 putative high outlier SNPs in the coral host and 4 in the algal symbiont. Differentiation of VA and RI populations in the coral host was driven by putatively adaptive loci, not neutral divergence (Fst = 0.16, p = 0.001 and Fst = 0.002, p = 0.269 for outlier and neutral SNPs respectively). In contrast, we found evidence of neutral population differentiation in B. psygmophilum (Fst = 0.093, p = 0.001). -

M. OPRESKO Life Sciences Division, Oak Ridge National Laboratory, 1060 Commerce Park, Oak Ridge, TN 37830, USA. ([email protected]) Abstract A new species of antipatharian coral (Anthozoa: Antipatharia) is described from the southern Cali- fornia Bight. The species, Antipathes dendrochristos new species, forms large, multi-branched, bushy colonies that can reach a height of 2 m or more. The species is characterized by having small branchlets arranged primarily bilaterally and alternately, but in varying degrees of regularity; by small conical spines less than 0.1 mm tall, and by small polyps usually less than 1.4 mm in trans- verse diameter. The species occurs in colors of white, orange/gold, pinkish-orange, pink, red, and red-brown. Key words: Coelenterata, Cnidaria, Anthozoa, Antipatharia, Antipathidae, Antipathes dendrochris- tos, new species, eastern Pacific, United States Introduction In late 2002 during a series of submersible surveys of rock fish populations on offshore banks in the southern California Bight, scientists from the National Oceanic and Atmo- spheric Administration (NOAA Fisheries), and the Univerity of California at Santa Bar- bara discovered a population of large antipatharian colonies (Fig. 1A), many over 2 meters tall, growing at depths of 100–225 meters. After examining samples of several of the col- onies and comparing them to type material of other nominal species, as well as to species descriptions in the literature, it was determined that the California specimens represented at least one, and possibly two, undescribed species. -

A new family of antipatharian corals, Myriopathidae (Cnidaria: Anthozoa: Antipatharia), is estab- lished for Antipathes myriophylla Pallas and related species. The family is characterized by polyps 0.5 to 1.0 mm in transverse diameter; short tentacles with a rounded tip; acute, conical to blade-like spines up to 0.3 mm tall on the smallest branchlets or pinnules; and cylindrical, simple, forked or antler-like spines on the larger branches and stem. Genera are differentiated on the basis of morphological fea- tures of the corallum. Myriopathes gen. nov., type species Antipathes myriophylla Pallas, has two rows of primary pinnules, and uniserially arranged secondary pinnules. Tanacetipathes Opresko, type species T. tanacetum (Pourtalès), has bottle-brush pinnulation with four to six rows of primary pinnules and one or more orders of uniserial (sometimes biserial) subpinnules. Cupressopathes gen. nov., type species Gorgonia abies Linnaeus, has bottle-brush pinnulation with four very irregular, or quasi-spiral rows of primary pinnules and uniserial, bilateral, or irregularly arranged higher order pinnules.
