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. -
Invertebrate Animals (Metazoa: Invertebrata) of the Atanasovsko Lake, Bulgaria
Historia naturalis bulgarica, 22: 45-71, 2015 Invertebrate Animals (Metazoa: Invertebrata) of the Atanasovsko Lake, Bulgaria Zdravko Hubenov, Lyubomir Kenderov, Ivan Pandourski Abstract: The role of the Atanasovsko Lake for storage and protection of the specific faunistic diversity, characteristic of the hyper-saline lakes of the Bulgarian seaside is presented. The fauna of the lake and surrounding waters is reviewed, the taxonomic diversity and some zoogeographical and ecological features of the invertebrates are analyzed. The lake system includes from freshwater to hyper-saline basins with fast changing environment. A total of 6 types, 10 classes, 35 orders, 82 families and 157 species are known from the Atanasovsko Lake and the surrounding basins. They include 56 species (35.7%) marine and marine-brackish forms and 101 species (64.3%) brackish-freshwater, freshwater and terrestrial forms, connected with water. For the first time, 23 species in this study are established (12 marine, 1 brackish and 10 freshwater). The marine and marine- brackish species have 4 types of ranges – Cosmopolitan, Atlantic-Indian, Atlantic-Pacific and Atlantic. The Atlantic (66.1%) and Cosmopolitan (23.2%) ranges that include 80% of the species, predominate. Most of the fauna (over 60%) has an Atlantic-Mediterranean origin and represents an impoverished Atlantic-Mediterranean fauna. The freshwater-brackish, freshwater and terrestrial forms, connected with water, that have been established from the Atanasovsko Lake, have 2 main types of ranges – species, distributed in the Palaearctic and beyond it and species, distributed only in the Palaearctic. The representatives of the first type (52.4%) predomi- nate. They are related to the typical marine coastal habitats, optimal for the development of certain species. -
A Simulation of the Distribution of Acartia Clausi During Oregon Upwelling, August 1973
Journal of Plankton Research Volume 2 Number 1 1980 A simulation of the distribution of Acartia clausi during Oregon Upwelling, August 1973 J.S.Wroblewski Department of Oceanography, Dalhousie University, Halifax, Nova Scotia B3H4J1, Canada Downloaded from https://academic.oup.com/plankt/article-abstract/2/1/43/1463810 by Old Dominion University user on 08 July 2019 (Received August 1979; revised November 1979; accepted December 1979) Abstract. The distribution of the estuarine copepod Acartia clausi in coastal waters off Oregon during an upwelling period in August 1973 is simulated. A time dependent, two dimensional (x, z, t) model relates maximum offshore extent of the copepod's four life stages (egg, nauplius, copepodite, and adult) to in- tensity of the wind stress driving the upwelling circulation, stage development time, and mortality. Realistic solutions are obtained by using actual intermittent wind forcing recorded by an anemometer at Newport. Offshore transport is overestimated when the circulation model is driven by theoretical con- tinuous winds, suggesting zooplankton may be washed out of coastal upwelling zones (e.g. off Northwest Africa) which undergo periods of prolonged upwelling. With an accurate model of offshore transport and stage development time, the mismatch between predicted and observed distributions may be used to estimate field mortality of the various stages. Introduction Zooplankton standing stock was once believed to be greater in the slope region off Oregon than over the continental shelf during the summer upwelling season. Peterson (1972) surveyed the oceanic, slope and shelf regions but did not sample the nearshore zone when making this conclusion. In a detailed study of the Oregon up- welling zone, Peterson and Miller (1975) found high concentrations of copepods in the upper 20 m of the water column within 15 km of the coast during the 1969-71 upwelling seasons, as did Myers (1975) in August, 1973. -

Species description Species name Acartia tonsa, Dana, 1849 – a planktonic copepod Synonyms Acartia (Acanthacartia) tonsa; Acartia giesbrechti Dahl, 1894; Acartia bermudensis Esterly, 1911; Acartia floridana Davis, 1948; Acartia gracilis Herrick, 1887; Acartia tonsa cryophylla Björnberg, 1963. Common names Aerjas tömbik (tulnuk-tömbik) (EE), Hankajalkaisäyriäinen (FI), Hoppkräfta (SE), Acartia, akartsia (RU) Identification Several similar species occur in the area: Acartia clausi Giesbrecht, 1889, A. longiremis (Liljeborg, 1853) and A. bifilosa (Giesbrecht, 1881). The latter species prefers low salinity waters (David et al., 2007), like A. tonsa, whereas A. clausi prefers high salinities (Calliari et al., 2006). A. longremis has a northern boreal-arctic distribution (Lee & McAlice, 1979), whereas A. clausi is widespread in warmer waters including the Mediterranean and Black Sea (Gubanova, 2000). Acartia tonsa is usually about 1 mm long (up to 1.5 mm) (Garmew et al., 1994; Belmonte et al., 1994; Marcus & Wilcox, 2007) and hence a microscope is required for identification. It has a relatively short abdomen, and relative body width is higher than in sympatric congeners. Females are only slightly larger than males, whereas in A. -

Several anthropogenic factors as well as environmental stressors concurred to make this ecosystem ideal for invasion. Given the zooplankton ecological relevance related to the role in the marine trophic network, changes in the community have implications for environmental management and ecosystem services. This work aims to depict the relevant steps of the history of invasion of the copepod Acartia tonsa in the Venice lagoon, providing a recent picture of its distribution, mainly compared to congeneric residents. In this work, four datasets of mesozooplankton were examined. The four datasets covered a period from 1975 to 2017 and were used to investigate temporal trends as well as the changes in coexistence patterns among the Acartia species before and after A. tonsa settlement. Spatial distribution of A. tonsa was found to be significantly associated with temperature, phytoplankton, particulate organic carbon (POC), chlorophyll a, and counter gradient of salinity, confirming that A. tonsa is an opportunistic tolerant species. As for previously dominant species, Paracartia latisetosa almost disappeared, and Acartia margalefi was not completely excluded. -

Seasonal Succession of Zooplankton Populations in Two Dissimilar Marine Embayments on the Oregon Coast
ANABSTRACTOF THE THESIS OF STEVEN THOMAS ZIMMERMAN for the DOCTOR OF PHILOSOPHY (Name of student) (Degree) in OCEANOGRAPHY presented on ): (Major) (Date) TITLE: SEASONAL SUCCESSION OF ZOO PLANKTON POPULATIONS IN TWO DISSIMILAR MARINE EMBAYMENTS ON THE OREGON COAST Redacted for Privacy Abstract approved: H. F. Frolander Zooplankton tows and hydrographic observations were made in two bays on the Oregon coast.Five stations were sampled weekly in Yaquina Bay from May,1969through September,1970. Three stations were sampled weekly in Netarts Bay from October,1969 through January,1961. Zooplankton collections were made with a a Clarke-Bumpus sampler towed in a series of oblique steps. A#6 mesh (.239 mm aperature) net was used, A one year period from October,1969through September, 1970 was used to make a compar- ison of location and succession of zooplankton populations in the two bays. Yaquina Bay is a dredged estuary receiving seasonally high river flow. A salinity gradient is found year round from the mouth to the head end of the bay.During the winter, when rainfall is high, salinities at the head end are very low.Netarts Bay has no large river flow and salinities are never greatly decreased due to large tidal mixing.The flushing time of Netarts Bay is very short and tidal exchange is high throughout the bay,Yaquina Bay has a rela- tively longer flushing time and tidal exchange is not as high in the head end of the bay as in Netarts Bay. Because of these physical differences large indigenous popula- tions of the estuarine copepods Acartia tonsa, Acartia clausi, and Eurytemora americana were found in Yaquina Bay.Indigenous popu- lations made a much smaller contribution to Netarts Bay, and only Eurytemora americana developed a population which was apparently confined to the bay. -
