Hiller & Lessios 2017
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). -

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. -

Morphological Description and Molecular Analysis of Newly Recorded Anneissia Pinguis(Crinoidea: Comatulida: Comatulidae) from Ko
Journal of Species Research 9(4):467-472, 2020 Morphological description and molecular analysis of newly recorded Anneissia pinguis (Crinoidea: Comatulida: Comatulidae) from Korea Philjae Kim1,2 and Sook Shin1,3,* 1Marine Biological Resource Institute, Sahmyook University, Seoul 01795, Republic of Korea 2Division of Ecological Conservation, Bureau of Ecological Research, National Institute of Ecology, Seocheon-gun, Chungnam 33657, Republic of Korea 3Department of Animal Biotechnology & Resource, Sahmyook University, Seoul 01795, Republic of Korea *Correspondent: [email protected] The crinoid specimens of the genus Anneissia were collected from Nokdong, Korea Strait, and Moseulpo, Jeju Island. The specimens were identified as Anneissia pinguis (A.H. Clark, 1909), which belongs to the family Comatulidae of the order Comatulida. Anneissia pinguis was first described by A.H. Clark in 1909 around southern Japan. This species can be distinguished from other Anneissia species by a longish and stout cirrus, much fewer arms, and short distal cirrus segments. The morphological features of Korean specimens are as follows: large disk (20-35 mm), 28-36 segments and 32-43 mm length cirrus, division series in all 4 (3+4), very stout and strong distal pinnule with 18-19 comb and 40 arms. In Korea fauna, only three species of genus Anneissia were recorded: A. intermedia, A. japonica, and A. solaster. In this study, we provide the morphological description and phylogenetic analysis based on cytochrome c oxidase subunit I.
