    www.nature.com/scientificreports OPEN Phylogeography of Petrolisthes armatus, an invasive species with low dispersal ability Received: 20 February 2017 Alexandra Hiller & Harilaos A. Lessios Accepted: 27 April 2017 Theoretically, species with high population structure are likely to expand their range, because marginal Published: xx xx xxxx populations are free to adapt to local conditions; however, meta-analyses have found a negative relation between structure and invasiveness. The crab Petrolisthes armatus has a wide native range, which has expanded in the last three decades. We sequenced 1718 bp of mitochondrial DNA from native and recently established populations to determine the population structure of the former and the origin of the latter. There was phylogenetic separation between Atlantic and eastern Pacific populations, and between east and west Atlantic ones. Haplotypes on the coast of Florida and newly established populations in Georgia and South Carolina belong to a different clade from those from Yucatán to Brazil, though a few haplotypes are shared. In the Pacific, populations from Colombia and Ecuador are highly divergent from those from Panamá and the Sea of Cortez. In general, populations were separated hundreds to million years ago with little subsequent gene flow. High genetic diversity in the newly established populations shows that they were founded by many individuals. Range expansion appears to have been limited by low dispersal rather than lack of ability of marginal populations to adapt to extreme conditions. The population-genetic constitution of marine invasive species in their native range is increasingly being stud- ied in efforts to determine the source of invasions into new areas (reviews in refs 1–5).

  • A New Bathyal Ophiacanthid Brittle Star (Ophiuroidea: Ophiacanthidae) with Caribbean Affinities from the Plio-Pleistocene of the Mediterranean

NUMBERGER-THUY & BEN THUY* Natural History Museum Luxembourg, Department of Palaeontology, 25, rue Münster, 2160 Luxembourg, Luxembourg; https://orcid.org/0000-0001-6097-995X *corresponding author: [email protected]; https://orcid.org/0000-0001-8231-9565 Abstract Identifiable remains of large deep-sea invertebrates are exceedingly rare in the fossil record. Thus, every new discovery adds to a better understanding of ancient deep-sea environments based on direct fossil evidence. Here we describe a collection of dissociated skeletal parts of ophiuroids (brittle stars) from the latest Pliocene to earliest Pleistocene of Sicily, Italy, preserved as microfossils in sediments deposited at shallow bathyal depths. The material belongs to a previously unknown species of ophiacanthid brittle star, Ophiacantha oceani sp. nov. On the basis of morphological comparison of skeletal microstructures, in particular spine articulations and vertebral articular structures of the lateral arm plates, we conclude that the new species shares closest ties with Ophiacantha stellata, a recent species living in the present-day Caribbean at bathyal depths. Since colonization of the deep Mediterranean following the Messinian crisis at the end of the Miocene was only possibly via the Gibraltar Sill, the presence of tropical western Atlantic clades in the Plio-Pleistocene of the Mediterranean suggests a major deep-sea faunal turnover yet to be explored.

POMORY 2007 Department of Biology, University of West Florida, 11000 University Parkway, Pensacola, FL 32514, USA. [email protected] ABSTRACT A key is given for 85 species of ophiuroids from the Gulf of Mexico and Caribbean Sea covering a depth range from the intertidal down to 30 m. Figures highlighting important anatomical features associated with couplets in the key are provided. 2 INTRODUCTION The Caribbean region is one of the major coral reef zoogeographic provinces and a region of intensive human use of marine resources for tourism and fisheries (Aide and Grau, 2004). With the world-wide decline of coral reefs, and deterioration of shallow-water marine habitats in general, ecological and biodiversity studies have become more important than ever before (Bellwood et al., 2004). Ecological and biodiversity studies require identification of collected specimens, often by biologists not specializing in taxonomy, and therefore identification guides easily accessible to a diversity of biologists are necessary.

  • Two New Brittle Star Species of the Genus Ophiothrix
    Caribbean Journal of Science, Vol. 41, No. 3, 583-599, 2005 Copyright 2005 College of Arts and Sciences University of Puerto Rico, Mayagu¨ez Two New Brittle Star Species of the Genus Ophiothrix (Echinodermata: Ophiuroidea: Ophiotrichidae) from Coral Reefs in the Southern Caribbean Sea, with Notes on Their Biology GORDON HENDLER Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, California 90007, U.S.A. [email protected] ABSTRACT.—Two new species, Ophiothrix stri and Ophiothrix cimar, inhabit shallow reef-platforms and slopes in the Southern Caribbean, and occur together at localities in Costa Rica and Panama, nearly to Colombia. What appears to be an undescribed species resembling O. cimar has been reported from eastern Venezuela. In recent years, reefs where the species were previously observed have deteriorated because of environmental degradation. As a consequence, populations of the new species may have been reduced or eradicated. The new species have previously been mistaken for O. angulata, O. brachyactis, and O. lineata. Ophiothrix lineata, O. stri, and O. cimar have in common a suite of morphological features pointing to their systematic affinity, and a similar pigmentation pattern consisting of a thin, dark, medial arm stripe flanked by two pale stripes. Ophiothrix lineata is similar to Indo-Pacific members of the subgenus Placophiothrix and closely resembles Ophiothrix stri. The latter is extremely similar to O. synoecina, from Colombia, and both can live in association with the rock-boring echinoid Echinometra lucunter. Although O. synoecina is a protandric hermaphrodite that reportedly broods its young externally, the new species are gonochoric and do not brood.

Numberger-Thuy • John W. M. Jagt Received: 19 July 2018 / Accepted: 14 September 2018 / Published online: 28 September 2018 Ó Akademie der Naturwissenschaften Schweiz (SCNAT) 2018 Abstract A small, albeit diverse, assemblage of dissociated ophiuroid ossicles, mostly lateral arm plates, from the upper Maas- trichtian Peedee Formation temporarily (August 1998) exposed at North Myrtle Beach (Horry County, South Carolina), is described and illustrated. This lot comprises at least seven species, five of which are new and formally named herein. The assemblage is of note in providing a significant expansion of the palaeobiogeographical record of latest Cretaceous brittle stars. Furthermore, it includes a new genus and species of the family Asteronychidae that is transitional between the stem euryalid Melusinaster and Recent asteronychids, as well as the oldest unambiguous fossil representative of the family Amphiuridae. Finally, this assemblage stands out in lacking Ophiotitanos and ophiomusaids, two of the most widely distributed and abundant brittle star taxa during the Late Cretaceous. Instead, it is dominated by members of the Amphilimnidae, Amphiuridae and Euryalida, which are amongst the rarest components in the faunal spectrum of modern- day equivalents. The assemblage represents a unique combination of taxa unknown from any other outcrops of upper Mesozoic rocks and seems to document the onset of modern shallow-sublittoral ophiuroid assemblages. Keywords Late Cretaceous Á North America Á New species Á Palaeoecology Introduction undertaken on a large scale in the United States.

The body of euryalids is covered by thick skin, and it is very difficult to observe the ossicles without dissolving the skin. Computed tomography with micrometer resolution (approximately 4.5–15.4 µm) was used to construct 3D images of skeletal ossicles and soft tissues in the ophiuroid’s body. Shape and positional arrangement of taxonomically important ossicles were clearly observed without any damage to the body.
