Daphnia Magna and Daphnia Longispina)

Castro1, M. A. Pardal2, F. Gonçalves1 1 Departamento de Biologia da Universidade de Aveiro & Centro de Estudos do Ambiente e do Mar (CESAM), Campus Universitário de Santiago, 3810-193 Aveiro, Portugal 2 IMAR, Departamento de Zoologia, Universidade de Coimbra, 3004-517 Coimbra, Portugal Salinity is a serious threat to freshwater ecosystems, particularly those near coastal areas. An increase in salinity produces drastic changes in community structure of freshwaters, sometimes in an irreversible fashion. Thus, freshwater species must cope with salinity stress in a manner proportional to their degree of tolerance. Bearing this in mind, we studied the acute and chronic effects of different salinity concentrations in two species of cladocerans: Daphnia magna Straus, a standard test organism, and Daphnia longispina O. F. Müller, an autochthonous species. Salinity experiments were based on successive dilutions of a stock solution of NaCl in a synthetic medium. The results showed that D. magna is more tolerant than D. longispina, both in acute (EC50 5.9 and 2.9 g/L, respectively) and chronic (EC50 5.0 and 2.2 g/L, correspondingly) exposures. In the chronic exposure, salinity caused a significant reduction in fecundity and a developmental delay (increase in age at first reproduction), as well as a decrease in the growth rate of daphnids. However, these effects were mainly observed at salinity concentrations where morta- lity occurred. Keywords: saline stress, sodium chloride, toxicity tests, freshwater zooplankton, life history. -

(1991): Moina weismanni Ishikawa, 1896, a rare East Palearctic faunistic element from S. W. Yugoslavia (Crustacea, Cladocera). — Spixiana 14/1: 1-7. Moina weismanni Ishikawa, 1896, tili recently was known as a rare Far-Eastern faunistic element. Some time ago this species was introduced in Europe and to date evidenced in some ricefields of North Italy and in several inondation pools of the Pa- nonian lowland. Our discovery of the species in S. W. Yugoslavia shows that it suc- ceded to inhabit the Balkan Peninsula, too. Based on specimens of both sexes collected from Macedonia a short description is given. In addition, some important features are emphasized. These include the form of the ephippium in dorsal aspect and the presence of rows of setae at the dorsal mar- gin of the postabdomen in the female. In the male, the armature of the ventral shell rim and the first pair of legs, which are mutually asymmetrical, are also significant diagno- stic characters. Swetozar T. Petkovski, Prirodonaucen muzej na Makedonija, Bulevar Ilinden 86, Yu-91 000, Skopje 55, Yugoslavia Introduction Moina weismanni Ishikawa is a rare anomopod 'cladoceran', which was described almost a Century ago from the vicinity of Tokio and Sendai, Japan (Ishikawa, 1896). Shortly afterwards, in his cultures reared from dried mud taken from fish ponds and inundated rice fields in the neighbourhood of Pu- ching, South China, Sars (1903) revealed an animal very similar to M. -
New and Previously Known Species of Copepoda and Cladocera (Crustacea) from Svalbard, Norway – Who Are They and Where Do They Come From?

Inta Dimante-Deimantovica1,4, Bjørn Walseng1, Elena S. Chertoprud2,3, and Anna A. Novichkova2,3 Dimante-Deimantovica I, Walseng B, Chertoprud ES and Novichkova A. 2018. New and previously known species of Copepoda and Cladocera (Crustacea) from Svalbard, Norway – who are they and where do they come from? Fauna norvegica 38: 18–29. Arctic landscapes are characterised by an immense number of fresh and brackish water habitats – lakes, ponds and puddles. Due to a rather harsh environment, there is a limited number of species inhabiting these ecosystems. Recent climate-driven regime shifts impact and change Arctic biological communities. New species may appear, and existing communities may become supressed or even disappear, depending on how ongoing changes match their ecological needs. This study provides data on presently existing and probably recently arrived fresh and brackish water microcrustacean species in the Norwegian High Arctic - Svalbard archipelago. The study focused on two taxonomic groups, Cladocera and Copepoda and altogether we found seven taxa new for Svalbard: Alona werestschagini, Polyphemus pediculus, Diaptomus sp., Diacyclops abyssicola, Nitokra spinipes, Epactophanes richardi and Geeopsis incisipes. Compared with an existing overview for the area, our study increased the number of species by more than 20 %, and some of the new species have never been found that far north. Finally, we present a complete and critically updated revised species list of fresh and brackish water cladocerans and copepods for Svalbard. -

Mihuc (faculty) Lake Champlain Research Institute, SUNY Plattsburgh, Plattsburgh, NY 12901 ABSTRACT This key was developed by undergraduate research students working on a project with NYDEC and the Lake Champlain Monitoring program to develop long-term data sets for Lake Champlain plankton. Funding for development of this key was provided by, the Lake Champlain Basin Program and the New York Department of Environmental Conservation (NYDEC). The key contains couplet keys for the major taxa in Cladocera and Copepoda and Rotifer plankton in Lake Champlain. Illustrations are by Erin Hayes-Pontius and Ian Ater. Many thanks to the employees of the Lake Champlain Research Institute for hours of excellent work in the field and in the lab: especially Casey Bingelli, Heather Bradley, Amanda Groves and Carrianne Pershyn. Keywords: Lake Champlain; zooplankton; identification; key INTRODUCTION Lake Champlain is one of the largest freshwater bodies in the United States. The Lake Champlain drainage basin is bordered by the Adirondack Mountains of New York to the west and the Green Mountains of Vermont to the east. This unique ecosystem has a surface area of 1130 km2, a length of 200 km and a mean depth of 19.4 m. The lake shoreline extends from Quebec in the north, 200 km south to Whitehall, New York, where it connects to the Hudson-Champlain canal. Islands and man-made transport causeways divide the lake into several distinct parts: Main Lake, South Lake, and Northeast Arm including Missisquoi Bay, and Malletts Bay. -

Population dynamics of Moina micrurs Kurz (Cladocera: Moinidae) inhabiting a eutrophic pond of Madurai (south India)* N MURUGAN Department of Zoology, Madura College, Madurai 625011. India MS received 13 July 1988; revised 10 March 1989 Abstract. Population density, composition, age structure and fecundity of Moina micrura have been studied in a eutrophic pond. The average clutch size of this species ranged from 1-4-4 eggs. The relationship between mean brood size and body length has been established. The volume of parthenogenetic eggs of this cladoceran ranges between 0·2 and 0·9 millions JL J and the adaptive significance of this has been discussed. The mean instantaneous birth rate which preceded maximum density of population resulted in a value of more than one. Keywords. Moina micrura; population density; composition; age structure; fecundity; egg volume. l. Introduction Moina micrura, a member of the family Moinidae primarily inhabits astatic ponds and pools in tropical and subtropical regions. This species is highly adapted to survive frequent dry periods and propagate rapidly in newly formed ponds. The review of literature on zooplankton species of Moina shows that the information about the population dynamics of M. micrura from tropical Indian waters is far from complete. Hence, an attempt has been made to investigate its population density and composition, fecundity and age structure in natural habitats. 2. Study area The present study was carried out in a seasonal shallow pond (figure 1) located in the Madura College campus at Madurai (Long: 78'8' E; Lat: 9'56' N), south India. -
Polyphemus Pediculus (L.) (Cladocera) As a Possible Indicator of Water Quality

Cladocera are eurybiotic organisms, therefore their role as specific indicators of the water quality is considered to be insignificant (Bening, 1941; Makrushin, 1976). If, however, we approach the evaluation of waters from the point of view of the method of Zelinka and Marvan (Zelinka M, Marvan P, 1961) which is based on the occurrence frequency of each of the detected species in various saprobic zones, the importance of Cladocera as the most numerous and widely spread species in the specification of waters greatly increases. On the basis of this method Cladocera at present are more and more often used as indicators of oligo- and mesosaprobic waters as well as of the presence of considerable amounts of easily degradable organic matter (Makrushin, 1976). Work over many years on the biology of Polyphemus pediculus, this striking representative of the order Cladocera, convinced us of the possibility of using this species not only as an indicator of water purity but also for the estimation of the degree of water pollution as well as of water characteristics such as colour, turbidity, oxgen content and chemical composition. -

Flynn Little is known of the biology and diversity of the environmental model genus Daphnia beyond the Nearctic and western Palearctic. Here, we describe Daphnia sinevi sp. nov., a species superficially similar to Daphnia curvirostris Eylmann, 1878, from the Far East of Russia. We estimated its phylogenetic position in the subgenus Daphnia s. str. with a rapidly evolving mitochondrial protein coding gene [NADH-2 (ND2)] and a nuclear protein-coding gene [heat shock protein 90 (HSP90)]. Daphnia curvirostris, D. sinevi sp. nov., Daphnia tanakai and D. sp. from Ootori- Ike, Japan, (which, probably, is D. morsei Ishikawa, 1895) formed a monophyletic clade modestly supported by ND2 and strongly supported by HSP90. Our results provide evidence of hidden species diversity in eastern Palearctic Daphnia, independent origins of defensive neckteeth and phylogenetic informativeness of nuclear protein-coding genes for zooplankton genera.
