Of the genus Pachylasma, only two species P. crinoidophilum PrLSBRY and P.japonicum HrRo have been known from Japan. A third species P. scutistriatum BROCH is newly added to the Japanese fauna. The other known species, P. ecaudatum HrRo formerly referred to Pachylasma, is now transferred to the genus Hexelasma, of which two species H. velutinum HoEK and H. callistoderma PILSBRY only have been so far known from Japan. An attempt to subdivide the family Chthamalidae into three subfamilies (Catophragminae, Chthamalinae and Pachylasminae) is newly presented. Syste~natic Account of the Japanese Species (Revised) Genus Pachylasma DARWIN, 1854 Diagnosis. Chthamalidae having a wall of eight compartments, in which the rostrum and rostrolaterals are united by inconspicuous, linear sutures, or are wholly con crescent in the adult stage, the wall thus becoming virtually six-plated. Radii wanting or very narrow and not well differentiated from the parietes. -

The thecostracan barnacles rank among the most commonly encountered marine crustaceans in the world. They deviate from almost all other Crustacea in that only the larvae are free-living, while the adults are permanently sessile and morphologically highly specialized as filter feeders or parasites. In the most recent classifications of the crustacean Maxillopoda 1 and latest phylogenetic analyses 2-4 the Thecostraca sensu Grygier 5, comprising the Facetotecta, Ascothoracida, and Cirripedia, form monophyletic assemblages. Barnacle phylogenetics has advanced greatly over the last 10 years. Nonetheless, the relationships and taxonomic status of some groups within these three infraclasses are still a matter of debate. While the barnacles where the focus of Darwin’s detailed taxonomic work, there has not been a comprehensive review of the species of barnacles as a whole since Darwin. As a consequence, the barnacle entries within the WoRMS Database is woefully out of date taxonomically and missing many, many species and higher taxa. -

All rights reserved Euraphia eastropacensis (Cirripedia, Chthamaloidea), a New Species ofBarnacle from the Tropical Eastern Pacific: Morphological and Electrophoretic Comparisons with Euraphia rhizophorae (deOliveira) from the Tropical Western Atlantic and Molecular Evolutionary Implications. 1 JORGE E. LAGUNA 2 ABSTRACT: Euraphia eastropacensis sp. nov., of the tropical Eastern Pacific, is distinguished from its tropical Western Atlantic congener, E. rhizophorae , by morphological and electrophoretic evidence. Because of the apparent recent radiation of high intertidal chthamaloids and the recent closure of the Isthmus ofPanama, one would expect that these two species ofEuraphia were geminates. However, utilizing electrophoretic data, a large genetic distance value (0.95) was found, and this creates difficulties when explaining speciation between the two in terms of the molecular clock. A molecular evolutionary interpretation of the data suggests that the two species may have speciated before the closure of the Isthmus of Panama, probably as early as the Upper Miocene. THE MARINE COMMUNITIES common to the ness, and to explain the evolutionary implica proto-Caribbean and the tropical Eastern tions raised with respect to the molecular Pacific were separated by the tectonic closure clock hypothesis. of the Isthmus of Panama 3 million years ago .

Pandit Aquatic Ecology Laboratory, Centre of Research for Development, University of Kashmir 190006, J&K (India) Abstract: The present study was carried out on Wular lake, the largest freshwater lake of India to obtain a baseline data on the dynamics of species composition and density of cladoceran zooplankton for the period of one year from September 2010 to August 2011 at five different study sites. Investigations revealed about 23 species of Cladocera belonging to six families were reported during the entire study. Among the six families, Chydoridae was numerically dominant, being represented by nine species, followed by Daphnidae with seven species, Bosminidae, Moinidae and Sididae with two species each and Macrothricidae with only one species. Shannon index was noticed highest for site III reflecting the stable environmental conditions of this biotope.

Barnacle Paper.PUB
Proc. Isle Wight nat. Hist. archaeol. Soc . 24 : 42-56. BARNACLES (CRUSTACEA: CIRRIPEDIA) OF THE SOLENT & ISLE OF WIGHT Dr Roger J.H. Herbert & Erik Muxagata To coincide with the bicentenary of the birth of the naturalist Charles Darwin (1809-1889) a list of barnacles (Crustacea:Cirripedia) recorded from around the Solent and Isle of Wight coast is pre- sented, including notes on their distribution. Following the Beagle expedition, and prior to the publication of his seminal work Origin of Species in 1859, Darwin spent eight years studying bar- nacles. During this time he tested his developing ideas of natural selection and evolution through precise observation and systematic recording of anatomical variation. To this day, his monographs of living and fossil cirripedia (Darwin 1851a, 1851b, 1854a, 1854b) are still valuable reference works. Darwin visited the Isle of Wight on three occasions (P. Bingham, pers.com) however it is unlikely he carried out any field work on the shore. He does however describe fossil cirripedia from Eocene strata on the Isle of Wight (Darwin 1851b, 1854b) and presented specimens, that were supplied to him by other collectors, to the Natural History Museum (Appendix). Barnacles can be the most numerous of macrobenthic species on hard substrata. The acorn and stalked (pedunculate) barnacles have a familiar sessile adult stage that is preceded by a planktonic larval phase comprising of six naupliar stages, prior to the metamorphosis of a non-feeding cypris that eventually settles on suitable substrate (for reviews on barnacle biology see Rainbow 1984; Anderson, 1994). Additionally, the Rhizocephalans, an ectoparasitic group, are mainly recognis- able as barnacles by the external characteristics of their planktonic nauplii. -
Genetic Population Structure of the Fairy Shrimp Branchinecta Coloradensis (Anostraca) in the Rocky Mountains of Colorado
Color profile: Disabled Composite Default screen 2049 Genetic population structure of the fairy shrimp Branchinecta coloradensis (Anostraca) in the Rocky Mountains of Colorado Andrew J. Bohonak Abstract: Dispersal rates for freshwater invertebrates are often inferred from population genetic data. Although genetic approaches can indicate the amount of isolation in natural populations, departures from an equilibrium between drift and gene flow often lead to biased gene flow estimates. I investigated the genetic population structure of the pond- dwelling fairy shrimp Branchinecta coloradensis in the Rocky Mountains of Colorado, U.S.A., using allozymes. Glaciation in this area and the availability of direct dispersal estimates from previous work permit inferences regarding the relative impacts of history and contemporary gene flow on population structure. Hierarchical F statistics were used θ θ to quantify differentiation within and between valleys ( SV and VT, respectively). Between valleys separated by 5– θ 10 km, a high degree of differentiation ( VT = 0.77) corresponds to biologically reasonable gene flow estimates of 0.07 individuals per generation, although it is possible that this value represents founder effects and nonequilibrium ≤ θ conditions. On a local scale ( 110 m), populations are genetically similar ( SV = 0.13) and gene flow is estimated to be 1.7 individuals exchanged between ponds each generation. This is very close to an ecological estimate of dispersal for B. coloradensis via salamanders. Gene flow estimates from previous studies on other Anostraca are also similar on comparable geographic scales. Thus, population structure in B. coloradensis appears to be at or near equilibrium on a local scale, and possibly on a regional scale as well.
