We conducted laboratory experiments on the host specificity of a natural enemy of the green crab, the parasitic barnacle Sacculina carcini, to provide information on the safety of its use as a possible biological control agent. Four species of non-target, native California crabs (Hemi- grapsus oregonensis, H. nudus, Pachygrapsus crassipes and Cancer magister) were exposed to infective lar- vae of S. carcini. Settlement by S. carcini on the four native species ranged from 33 to 53%, compared to 79% for green crabs. Overall, cyprid larvae tended to settle in higher numbers on individual green crabs than on either C. magister or H. oregonensis. However, for C. magister this difference was signifi- cant for soft-shelled, but not hard-shelled individuals. -

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

BOSGHMA The Rhizocephala, parasites of Crustacea of various orders, form a small group of animals, of which the comparatively small number of published records become rather easily accessible in a complete manner, so that in this respect the group lends itself for a survey of the occurrence and the distribu- tion of the species in the Pacific area. The available data are widely scattered in the literature (cf. references at the end of the present paper), most papers dealing with one or a few species, some publications containing data on animals of the group from a distinct geographical area, others again giving the results of an examination of the material of the group preserved in a certain museum. A survey of the available data proves that in certain regions of the Pacific our knowledge concerning the Rhizocephala is fairly well advanced, whilst on the other hand in other parts of the area hardly anything has become known in respect to the parasites of the group. A list of the species known to occur in the Pacific region follows here, arranged under the various genera. To save space the author's names Boschma (B.), Van Kampen & Boschma (K. B.), and Shiino (Sh.) have been abbreviated as indicated in brackets. Behind each name one or more numbers are added in brackets, these refer to the geographical areas briefly to be indicated as: I, Japan; 2, China; 3, Philippine Islands; 4, South East Asia; 5, East Indian Archipelago; 6, New Guinea and Torres Strait; 7, North East and East Australia; 8, North America, including Bering Sea; 9, South America; 10, Central Pacific. -

Larval Morphology of the Spider Crab Leurocyclus Tuberculosus (Decapoda: Majoidea: Inachoididae)

E-mail: [email protected] Abstract Within the recently resurrected family Inachoididae is Leurocyclus tuberculosus, an inachoidid spider crab distributed throughout the Western Atlantic of South America from Brazil to Argentina (including Patagonia), and along the Eastern Pacific coast of Chile. The larval development of L. tuberculosus consists of two zoeal stages and one megalopa. We observed that the larval morphology of L. tuberculosus conforms to the general pattern found in Majoidea by having two zoeal stages, in which the first stage has nine or more seta on the scaphognatite of the maxilla, and the second zoeal stage present well developed pleopods. Here, we describe the larval morphology of L. tuberculosus and compare with other inachoidid members for which we have larval information.

Seasonal Variation in Community Structure and Recruitment of Benthic Decapods in a Sub-Tidal Cobble Habitat
MARINE ECOLOGY PROGRESS SERIES Vol. 206: 181–191, 2000 Published November 3 Mar Ecol Prog Ser Seasonal variation in community structure and recruitment of benthic decapods in a sub-tidal cobble habitat Martin Robinson*, Oliver Tully Department of Zoology, Trinity College, Dublin, Ireland ABSTRACT: Quantitative suction samples of benthic decapod fauna were taken in the south of Ireland during 1997. Some species settled into the area, but failed to persist to the first winter, while others were present in high numbers throughout the year. The duration of settlement was species- specific, ranging from several weeks to several months. Body size at settlement decreased with increasing temperature during larval development. Growth potential and early mortality of a number of decapod species was examined by separation of successive moult instars from length-frequency distributions. Seasonal lows in abundance and biomass of young of the year and for previously estab- lished decapod individuals were identified at the end of July and early August, which may represent the most suitable time to release juveniles for stock-enhancement purposes. Community structure differed between settlement season and over-wintering periods. Young-of-the-year community structure differed from that of previously established individuals, with higher abundance and num- ber of species recorded for the former. The data represent a baseline study of a widely distributed community and may support further work on species interactions, improving the accuracy of predic- tion of annual recruitment fluctuations.

Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans
Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans by Robert George Young A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Robert George Young, March, 2016 ABSTRACT MOLECULAR SPECIES DELIMITATION AND BIOGEOGRAPHY OF CANADIAN MARINE PLANKTONIC CRUSTACEANS Robert George Young Advisors: University of Guelph, 2016 Dr. Sarah Adamowicz Dr. Cathryn Abbott Zooplankton are a major component of the marine environment in both diversity and biomass and are a crucial source of nutrients for organisms at higher trophic levels. Unfortunately, marine zooplankton biodiversity is not well known because of difficult morphological identifications and lack of taxonomic experts for many groups. In addition, the large taxonomic diversity present in plankton and low sampling coverage pose challenges in obtaining a better understanding of true zooplankton diversity. Molecular identification tools, like DNA barcoding, have been successfully used to identify marine planktonic specimens to a species. However, the behaviour of methods for specimen identification and species delimitation remain untested for taxonomically diverse and widely-distributed marine zooplanktonic groups. Using Canadian marine planktonic crustacean collections, I generated a multi-gene data set including COI-5P and 18S-V4 molecular markers of morphologically-identified Copepoda and Thecostraca (Multicrustacea: Hexanauplia) species. I used this data set to assess generalities in the genetic divergence patterns and to determine if a barcode gap exists separating interspecific and intraspecific molecular divergences, which can reliably delimit specimens into species. I then used this information to evaluate the North Pacific, Arctic, and North Atlantic biogeography of marine Calanoida (Hexanauplia: Copepoda) plankton. -
