The phylogenetic position of the solitary zoanthid genus Sphenopus (Cnidaria: Hexacorallia)
Provedor de dados: 16
Autores: Reimer, J.D.; Lin, M.; Fujii, T.
The zoanthid genus Sphenopus (Cnidaria: Anthozoa: Zoantharia), like many other brachycnemic zoanthids, is found in shallow subtropical and tropical waters, but is uniquely unitary (solitary, monostomatous), azooxanthellate, and free-living. With sparse knowledge of its phylogenetic position, this study examines the phylogenetic position of Sphenopus within the family Sphenopidae utilizing specimens from southern Taiwan and Brunei collected in 1999-2011, and furthermore analyzes the evolution of its unique character set via ancestral state reconstruction analyses. Phylogenetic analyses surprisingly show Sphenopus to be phylogenetically positioned within the genus Palythoa, which is colonial (polystomatous), zooxanthellate, and attached to solid substrate....

Zoanthids of the Cape Verde Islands and their symbionts: previously unexamined diversity in the Northeastern Atlantic
Provedor de dados: 16
Autores: Reimer, J.D.; Hirose, M.; Wirtz, P.
The marine invertebrate fauna of the Cape Verde Islands contains many endemic species due to their isolated location in the eastern Atlantic, yet research has not been conducted on most taxa here. One such group are the zoanthids or mat anemones, an order of benthic cnidarians (Hexacorallia: Zoantharia) common in many marine environments. In this study, the diversity of zoanthids in the Cape Verde Islands is specifically examined for the first time. Field images and sampling are combined with molecular phylogenetic analyses utilizing two mitochondrial DNA markers (cytochrome oxidase subunit I and 16S ribosomal DNA) to determine the number of species present. Specimens from eight species (Palythoa caribaeorum, Palythoa sp. 265, Zoanthus aff. pulchellus,...

Zoantharia (Cnidaria: Anthozoa: Hexacorallia) of the South China Sea and Gulf of Thailand: a species list based on past reports and new photographic records
Provedor de dados: 16
Autores: Reimer, J.D.; Wee, H.B.; Put, A.; Hoeksema, B.W.
This study is the first review of Zoantharia species in the South China Sea and Gulf of Thailand. In addition to past literature records, new field observations are added from previously unexamined countries and regions. In total 16 species are listed, 15 of which belong to suborder Brachycnemina, and only one to suborder Macrocnemina. Two species are undescribed. The lack of Macrocnemina species is not likely indicative of a low diversity of this suborder in the South China Sea and Gulf of Thailand, but instead of an absence of research below shallow subtidal depths. As the majority of the new records from this study were randomly compiled by researchers who are not experts of Zoantharia, specific surveys by experts are needed in these two marine regions....

NA phylogeny of Ryukyus Leucothoidae (Crustacea: Amphipoda)
Provedor de dados: 16
Autores: White, K.N.; Reimer, J.D.
Commensal leucothoid amphipods collected from sponges, ascidians, and coral rubble from the Ryukyu Archipelago, Japan, were investigated using nuclear 18S ribosomal DNA sequences. Analysis of sequences from 21 species in three genera supported the current morphological species designations and the separation of the family into two clades. Additionally, a possible new generic-level clade was identified and the separation of the genera Anamixis and Paranamixis was not supported. Our results demonstrate that host specificity appears to evolve rapidly in sibling species in this family.
