Diversity and Life-Cycle Analysis of Pacific Ocean Zooplankton by Video Microscopy and DNA Barcoding: Crustacea
Journal of Aquaculture & Marine Biology Research Article Open Access Diversity and life-cycle analysis of Pacific Ocean zooplankton by video microscopy and DNA barcoding: Crustacea Abstract Volume 10 Issue 3 - 2021 Determining the DNA sequencing of a small element in the mitochondrial DNA (DNA Peter Bryant,1 Timothy Arehart2 barcoding) makes it possible to easily identify individuals of different larval stages of 1Department of Developmental and Cell Biology, University of marine crustaceans without the need for laboratory rearing. It can also be used to construct California, USA taxonomic trees, although it is not yet clear to what extent this barcode-based taxonomy 2Crystal Cove Conservancy, Newport Coast, CA, USA reflects more traditional morphological or molecular taxonomy.

From 1042 specimens, 544 COI sequences were obtained falling into 199 Barcode Identification Numbers (BINs), of which 76 correspond to recognized species.

We compared 16S rRNA sequences of bacterial strains isolated from stomachs of healthy krill Nyctiphanes simplex specimens with sequences of bacterial isolates and sequences of natural bacterial communities from the hemocoel of N. simplex specimens infected with P. brintoni to determine possible trans- mission pathways. All P. brintoni endoparasitic life stages and the transmission tomite stage (out- side the host) were associated with bacterial assemblages. -
Parasite Diversity of Nyctiphanes Simplex and Nematoscelis Difficilis (Crustacea: Euphausiacea) Along the Northwestern Coast of Mexico

C.P. 04510, México 3Australian Antarctic Division, Department of Environment, Water, Heritage and Arts, 203 Channel Highway, Kingston, Tasmania 7050, Australia ABSTRACT: The diversity of parasites found on Nyctiphanes simplex and Nematoscelis difficilis (Order Euphausiacea) was compared during 10 oceanographic cruises made off both coasts of the Baja California peninsula, Mexico. We tested the hypothesis that N. simplex has a more diverse para- sitic assemblage than N. difficilis because it is a neritic species, has larger population abundance, and tends to form denser and more compact swarms than N. difficilis. These biological and behavioral features may enhance parasite transmission within swarms. We detected 6 types of ectoparasites: (1) epibiotic diatoms Licmophora sp.; (2) Ephelotidae suctorian ciliates; (3) Foettingeriidae exu- viotrophic apostome ciliates; (4) an unidentified epicaridean cryptoniscus larvae (isopoda); and 2 cas- trators: (5) the ectoparasitic Dajidae isopod Notophryxus lateralis and (6) the ellobiopsid mesopara- site Thalassomyces fagei. We also detected 7 types of endoparasites: (1) an undescribed Collinia ciliate (Apostomatida); 3 types of Cestoda: (2) a Tetrarhynchobothruium sp. -
Kawamura, A. a Review of Food of Balaenopterid Whales. 155-197
A REVIEW OF FOOD OF BALAENOPTERID WHALES AKITO KAWAMURA Faculty of Fisheries, Hokkaido University, Hakodate, Hokkaido ABSTRACT In order to elucidate what species among so many kind of marine organ isms are likely to be consumed largely by the balaenopterid whales, the ex isting evidence on the food habits of baleen whales is reviewed. To meet with this primary purpose the report was mainly focussed on to describe qualitative aspects of food species having been known to date from the notable whaling grounds over the world rather than documenting quantitative subjects.' One of interesting facts noticed throughout the contribution was that there exists fairly intense diversity in the assembly of food species composition by regions such as; northern hemisphere vs. southern hemisphere, Pacific region vs. Atlantic region, inshore waters vs. offshore waters, embayed waters vs. open waters, where the former usually shows more div'ersed complexity than the latter. The fact however suggests that although the composition of food spe cies locally varies over the various whaling grounds, the food organisms as taxonomical groups are very similar one another even in locally isolated whal ing grounds when the food organisms and their assemblies are considered by the family or genus basis. In this connection many evidences given in the text may suggest that the balaenopterid whales as a whole may substantially live on quite simply compositioned forage assembly in comparison with tre mendous variety of organisms existing in the marine ecosystems. One of im portant aspects of the baleen whales food must be found in their characteris tics of forming dense swarms, schools, and/or aggregations in the shallower enough layers to be fed by the whales. -

Nematoscelis Megalops (Euphausiacea) in the Northern Benguela Current: Ecological Significance of Vertical Space Partitioning

Diet and feeding of Euphausia hanseni and Nematoscelis megalops (Euphausiacea) in the northern Benguela Current: ecological significance of vertical space partitioning Manuel ~arange'.',Mark J. Gibbons2.3, Marta Carola4 ' Instituto de Ciencias del Mar, Paseo Nacional s/n, E-08039 Barcelona, Spain Marine Biology Research Institute. Department of Zoology, University of Cape Town, Rondebosch 7700, South Africa Sea Fisheries Research Institute, Private Bag X2, Rogge Bay 8012, South Africa Departamento de Ecologia, Facultad de Biologia, Universidad de Barcelona, Diagonal 645, E-08028 Barcelona, Spain ABSTRACT: Patterns of diel migration and feeding of Euphausia hanseni and Nernatoscelis rnegalops were investigated in waters of the northern Benguela (Namibia) upwelling system. N. megalops migrated to just below the thermocline at night and fed maximally in the early evening E. hanseni migrated to above the thermocline at night and fed progressively throughout the night. Although both species were omnivorous and consumed similar size ranges of copepod prey, differential prey size- frequency with depth resulted in E. hanseni consuming mostly small-sized copepods and N. megalops preferring medum size classes. At depths of overlap the 2 species appeared to partition copepod food resources on the basis of size. Verhcal spatial partitioning is examined in light of temporal and dietary separation, and overlapping horizontal distribution patterns of the species in the northern Benguela upwelling system. It is concluded that vertical space partitioning is a reflection of the structure of shelf break zooplankton communities, which is a strategy of sharing highly productive areas and avoiding competition.
