The aim of this study was to assess the spatial variations in the copepod community abundance, and the biomass and production patterns of the three most abundant calanoid species in the SPSPA. Plankton samples were collected with a 300 µm mesh size net along four transects (north, east, south and west of the SPSPA), with four stations plotted in each transect. All transects exhibited a tendency toward a decrease in copepod density with increasing distance from the SPSPA, statistically proved in the North. Density varied from 3.33 to 182.18 ind.m-3, and differences were also found between the first perimeter (first circular distance band) and the others. The total biomass varied from 15.25 to 524.50 10-3 mg C m-3 and production from 1.19 to 22.04 10-3 mg C m-3d-1. -

Received 7/12/84, in revised form 21/10/85, accepted 5/11/85, ABSTRACT Recent studies on the calanoid copepods of the northern Indian Ocean show that about 183 species occur frequently in the epipelagic realm. Fifteen more epipelagic species reported from this region occur only rarely. Another 45 species have been recorded which appear to be deep-water forms sporadically migrating to the upper layer and encountered there in low numbers. 40 species are fairly ubiquitous; many of them are often dominant components of the copepod community. The present study shows more homogeneity between the Indian and Pacifie fauna than between those of the Indian and Atlantic Oceans. Distributions, abundances and zoogeography of various calanoid species are discussed. Species assemblages are more or Jess homogeneous and the major zonation is the estuarine-neritic-oceanic ranges of the component species. Variations in the structure and niches of calanoid communities in oligotrophic and eutrophie waters are discussed, Oceanol. -

Lyngby, Denmark; [email protected] * Correspondence: [email protected] Received: 30 March 2020; Accepted: 6 May 2020; Published: 11 May 2020 Abstract: Calanoid copepods have two swimming gaits, namely cruise swimming that is propelled by the beating of the cephalic feeding appendages and short-lasting jumps that are propelled by the power strokes of the four or five pairs of thoracal swimming legs. The latter may be 100 times faster than the former, and the required forces and power production are consequently much larger. Here, we estimated the magnitude and size scaling of swimming speed, leg beat frequency, forces, power requirements, and energetics of these two propulsion modes. We used data from the literature together with new data to estimate forces by two different approaches in 37 species of calanoid copepods: the direct measurement of forces produced by copepods attached to a tensiometer and the indirect estimation of forces from swimming speed or acceleration in combination with experimentally estimated drag coefficients. Depending on the approach, we found that the propulsive forces, both for cruise swimming and escape jumps, scaled with prosome length (L) to a power between 2 and 3. -

[email protected] 1. Brief definition of the group and main diagnosing characters The Harpacticoida is one of the orders of the subclass Copepoda, and includes mainly free-living epibenthic aquatic organisms, although many species have successfully exploited other habitats, including semi-terrestial habitats and have established symbiotic relationships with other metazoans. Harpacticoids have a size range between 0.2 and 2.5 mm and have a podoplean morphology. This morphology is char- acterized by a body formed by several articulated segments, metameres or somites that form two separate regions; the anterior prosome and the posterior urosome. The division between the urosome and prosome may be present as a constriction in the more cylindric shaped harpacticoid families (e.g. Ectinosomatidae) or may be very pronounced in other familes (e.g. Tisbidae). The adults retain the central eye of the larval stages, with the exception of some underground species that lack visual organs. The harpacticoids have shorter first antennae, and relatively wider urosome than the copepods from other orders. The basic body plan of harpacticoids is more adapted to life in the benthic environment than in the pelagic environment i.e. they are more vermiform in shape than other copepods. Harpacticoida is a very diverse group of copepods both in terms of morphological diversity and in the species-richness of some of the families. -

Taxonomy, biology and phytogeny of Miraciidae (Copepoda: Harpacticoida). - Sarsia 79:207-283. Bergen. ISSN 0036-4827. The holoplanktonic family Miraciidae (Copepoda, Harpacticoida) is revised and a key to the four monotypic genera presented. Amended diagnoses are given for Miracia Dana, Oculosetella Dahl and Macrosetella A. Scott, based on complete redescriptions of their respective type species M. efferata Dana, 1849, O. gracilis (Dana, 1849) and M. gracilis (Dana, 1847). A fourth genus Distioculus gen. nov. is proposed to accommodate Miracia minor T. Scott, 1894. The occurrence of two size-morphs of M. gracilis in the Red Sea is discussed, and reliable distribution records of the problematic O. gracilis are compiled. The first nauplius of M. gracilis is described in detail and changes in the structure of the antennule, P2 endopod and caudal ramus during copepodid development are illustrated. Phylogenetic analysis revealed that Miracia is closest to the miraciid ancestor and placed Oculosetella-Macrosetella at the terminal branch of the cladogram. Various aspects of miraciid biology are reviewed, including reproduction, postembryonic development, verti cal and geographical distribution, bioluminescence, photoreception and their association with filamentous Cyanobacteria {Trichodesmium).
