NEW RECORDS OF ELLOBIOPSIDAE (PROTISTA (INCERTAE SEDIS» FROM THE NORTH PACIFIC WITH A DESCRIPTION OF THALASSOMYCES ALBATROSSI N.SP., A PARASITE OF THE MYSID STILOMYSIS MAJOR BRUCE L. WINGl ABSTRACT Ten species of ellobiopsids are currently known to occur in the North Pacific Ocean-three on mysids and seven on other crustaceans. Thalassomyces boschmai parasitizes mysids of genera Acanthomysis, Neomysis, and Meterythrops from the coastal waters of Alaska, British Columbia, and Washington. Thalassomyces albatrossi n.sp. is described as a parasite of Stilomysis major from Korea. Thalassomyces fasciatus parasitizes the pelagic mysids Gnathophausia ingens and G. gracilis from Baja California and southern California. Thalassomyces marsupii parasitizes the hyperiid amphipods Parathemisto pacifica and P. libellula and the lysianassid amphipod Cypho caris challengeri in the northeastern Pacific. Thalassomyces fagei parasitizes euphausiids of the genera Euphausia and Thysanoessa in the northeastern Pacific from the southern Chukchi Sea to southern California, and occurs off the coast of Japan in the western Pacific. Thalassomyces capillosus parasitizes the decapod shrimp Pasiphaea pacifica in the northeastern Pacific from Alaska to Oregon, while Thalassomyces californiensis parasitizes Pasiphaea emarginata from central California. An eighth species of Thalassomyces parasitizing pasiphaeid shrimp from Baja California remains undescribed. Ellobiopsis chattoni parasitizes the calanoid copepods Metridia longa and Pseudocalanus minutus in the coastal waters of southeastern Alaska. Ellobiocystis caridarum is found frequently on the mouth parts ofPasiphaea pacifica from southeastern Alaska. An epibiont closely resembling Ellobiocystis caridarum has been found on the benthic gammarid amphipod Rhachotropis helleri from Auke Bay, Alaska. Where sufficient data are available, notes on variability, seasonal occurrence, and effects on the hosts are presented for each species of ellobiopsid. -
Bioluminescence As an Ecological Factor During High Arctic Polar Night Heather A
www.nature.com/scientificreports OPEN Bioluminescence as an ecological factor during high Arctic polar night Heather A. Cronin1, Jonathan H. Cohen1, Jørgen Berge2,3, Geir Johnsen3,4 & Mark A. Moline1 Bioluminescence commonly infuences pelagic trophic interactions at mesopelagic depths. Here receie: 01 pri 016 we characterize a vertical gradient in structure of a generally low species diversity bioluminescent ccepte: 14 Octoer 016 community at shallower epipelagic depths during the polar night period in a high Arctic ford with in Puise: 0 oemer 016 situ bathyphotometric sampling. Bioluminescence potential of the community increased with depth to a peak at 80 m. Community composition changed over this range, with an ecotone at 20–40 m where a dinofagellate-dominated community transitioned to dominance by the copepod Metridia longa. Coincident at this depth was bioluminescence exceeding atmospheric light in the ambient pelagic photon budget, which we term the bioluminescence compensation depth. Collectively, we show a winter bioluminescent community in the high Arctic with vertical structure linked to attenuation of atmospheric light, which has the potential to infuence pelagic ecology during the light-limited polar night. Light and vision play a large role in interactions among organisms in both the epipelagic (0–200 m) and mesope- lagic (200–1000 m) realms1,2. Eye structure and function in these habitats is commonly adapted for photon capture in the underwater light feld, with increasing specialization in the mesopelagic3. To avoid visual detection, species in epi- and mesopelagic habitats employ cryptic strategies such as transparency4 and counter-illumination5,6, along with diel vertical migration7,8, to remain hidden from potential predators. -
Vertical Distribution of Calanus Spp. and Metridia Longa at Four Arctic Locations
Marine Biology Research, 2008; 4: 193Á207 ORIGINAL ARTICLE Vertical distribution of Calanus spp. and Metridia longa at four Arctic locations MALIN DAASE1, KETIL EIANE1,3, DAG L. AKSNES2 & DANIEL VOGEDES1 1The University Centre in Svalbard, Longyearbyen, Norway, 2Department of Biology, University of Bergen, Bergen, Norway, and 3The University College in Bodø, Norway Abstract We investigated the vertical distribution of Calanus finmarchicus, C. glacialis, C. hyperboreus and Metridia longa at four locations around the archipelago of Svalbard in autumn. The older and larger copepodites of Calanus spp. were generally located deeper in the water column. Differences in vertical distribution between stations partly reflected a southÁnorth gradient in developmental progress with higher abundance of older stages in the southern locations. The C. finmarchicus and M. longa observations were consistent with the hypothesis that the developmental stages distributed according to certain preferences for light intensity, and different optical properties at the four locations are likely to have affected the vertical distributions. Diel vertical migration was only observed for older developmental stages of M. longa while young stages of M. longa remained in deep waters both day and night. A mortality index indicated that non-migrating Calanus spp. suffered higher mortality than migrating M. longa. Key words: Calanus, Metridia longa, mortality, optics, vertical distribution Introduction along the vertical axis in the sea is to some extent due to the rapid attenuation of light in water (Jerlov The depth distribution of many copepods in cold- 1968). This sets up thermal stratification and limits temperate regions is characterized by a strong seasonality that is closely related to the annual cycle the depth range available for positive primary produc- in primary production (Vinogradov 1997). -

This process aims to achieve the Good Environmental Status (GES) through the elaborated 11 Ecological Objectives and their respective common indicators. Since 2008, Contracting Parties to the Barcelona Convention have adopted the EcAp and agreed on a roadmap for its implementation. First phases of the EcAp process led to the accomplishment of 5 steps of the scheduled 7-steps process such as: 1) Definition of an Ecological Vision for the Mediterranean; 2) Setting common Mediterranean strategic goals; 3) Identification of an important ecosystem properties and assessment of ecological status and pressures; 4) Development of a set of ecological objectives corresponding to the Vision and strategic goals; and 5) Derivation of operational objectives with indicators and target levels. -

Clutch sizes and sperm storage potential were determined for females captured from the southeastern Bering Sea and Gulf of Alaska. None of the females produced more than one egg clutch in captivity. The mean clutch size was 12-13 eggs.d-1 for females from both sites and there was no relationship between body size and number of eggs per clutch or egg diameter, Intermolt periods for the egg through N IV stages were 4 9-120 hours for animals reared at 3°C, 33-69 hours at 6°C and 27-74 hours at 9°C. -
Observing Copepods Through a Genomic Lens James E Bron1*, Dagmar Frisch2, Erica Goetze3, Stewart C Johnson4, Carol Eunmi Lee5 and Grace a Wyngaard6
Bron et al. Frontiers in Zoology 2011, 8:22 http://www.frontiersinzoology.com/content/8/1/22 DEBATE Open Access Observing copepods through a genomic lens James E Bron1*, Dagmar Frisch2, Erica Goetze3, Stewart C Johnson4, Carol Eunmi Lee5 and Grace A Wyngaard6 Abstract Background: Copepods outnumber every other multicellular animal group. They are critical components of the world’s freshwater and marine ecosystems, sensitive indicators of local and global climate change, key ecosystem service providers, parasites and predators of economically important aquatic animals and potential vectors of waterborne disease. Copepods sustain the world fisheries that nourish and support human populations. Although genomic tools have transformed many areas of biological and biomedical research, their power to elucidate aspects of the biology, behavior and ecology of copepods has only recently begun to be exploited. Discussion: The extraordinary biological and ecological diversity of the subclass Copepoda provides both unique advantages for addressing key problems in aquatic systems and formidable challenges for developing a focused genomics strategy. This article provides an overview of genomic studies of copepods and discusses strategies for using genomics tools to address key questions at levels extending from individuals to ecosystems. Genomics can, for instance, help to decipher patterns of genome evolution such as those that occur during transitions from free living to symbiotic and parasitic lifestyles and can assist in the identification of genetic mechanisms and accompanying physiological changes associated with adaptation to new or physiologically challenging environments. The adaptive significance of the diversity in genome size and unique mechanisms of genome reorganization during development could similarly be explored. -
