Shadrin* and Elena V. Anufriieva Department of Marine Animal Physiology and Biochemistry, Institute of Biology of the Southern Seas, 2 Nakhi- mov ave., 99011, Sevastopol, Ukraine *Corresponding author: [email protected] Key words: Copepoda, Arctodiaptomus salinus, hypersaline lakes, osmolytes, Crimea, metabolism of community. Abstract Arctodiaptomus salinus is a widespread species in different regions including Mediterranean. Long-term study has shown the presence of the species in the Crimean lakes under the salinity from 5 to 210 ‰. The logarithm of the species density in a lake is inversely proportional to salinity. Earlier experimental studies have shown that the upper salinity limit of the species is 70- 100 ‰. Authors explain this discrepancy of field and experimental data that at salinities above 70-100 ‰ copepods consume exoosmolytes, mainly with food. A. salinus is an osmokonformer; to survive under osmotic stress it utilizes mechanisms of the cellular level – accumulates the osmolytes. Every time when we found A. salinus under high salinities, we observed unicellular green algae Dunaliella salina bloom. D. salina intensifies the synthesis of osmolytes under high salinities, which can be up to 80 % of the dry weight of the cells. Probably A. salinus gets enough osmolytes by consuming Dunaliella to live under salinities above 70 ‰. Conclusions: The halotolerance limit of A. salinus is not determined purely by its physiology; the metabolism of community, as a whole, determines the upper limit of halotolerance of animals-conformers. -

Elimination of Dengue by Control of Aedes Vector Mosquitoes (Diptera: Culicidae) Utilizing Copepods (Copepoda: Cyclopidae)
International Journal of Bioinformatics and Biomedical Engineering Vol. 1, No. 2, 2015, pp. 101-106 http://www.aiscience.org/journal/ijbbe Elimination of Dengue by Control of Aedes Vector Mosquitoes (Diptera: Culicidae) Utilizing Copepods (Copepoda: Cyclopidae) Muhammad Sarwar * Nuclear Institute for Agriculture & Biology, Faisalabad, Punjab, Pakistan Abstract This paper reports on the information and result of long-term laboratory and field studies on copepods (Copepoda: Cyclopidae) as predators for mosquito control inhabiting in tropic and subtropic environments. Mosquitoes have long been vectors of numerous diseases that affect human health and well-being in many parts of the world. Reducing the use of pesticides against insect vectors is one of the big demands of the society because public has always been against the heavy use of insecticides. Copepods are natural and tiny shrimp-like crustacean with a hearty appetite for feeding on mosquito larvae in water holding areas. The copepods thrive in fresh and marine water, and are valuable tool in battling mosquitoes in artificial containers, roadside ditches, small water pools, clogged downspouts and other wet areas that can breed plenty of mosquitoes. These are especially helpful tools in fighting mosquitoes near public places, where use of certain pesticides is restricted. Copepods are relatively easy to culture, maintain and deliver to the target areas, but getting the cultures started requires some effort and time. Copepods are more efficient predator of younger than of older larvae of mosquito and predation drops considerably for 4 days and older larvae. Copepods though prefer to prey on younger larvae, yet also increasingly attack on older larvae as greater predator densities reduce the supply of younger ones. -
Ctenodiaptomus) Praedictus Sulawensis Alekseev & Vaillant, 2013 (Hexanauplia, Copepoda, Calanoida, Diaptomidae) in the Philippines (Luzon Island
PRIMARY RESEARCH PAPER | Philippine Journal of Systematic Biology New record of Phyllodiaptomus (Ctenodiaptomus) praedictus sulawensis Alekseev & Vaillant, 2013 (Hexanauplia, Copepoda, Calanoida, Diaptomidae) in the Philippines (Luzon Island) Shea Kathleen P. Guinto1, Justine Val Jade B. Lacaba2, John Kenneth V. Cuballes2, Aezrile A. Igancio2, Eric Zeus C. Rizo3, Henri J. Dumont3,4, Bo-Ping Han3 & Rey Donne S. Papa1,2,5* ABSTRACT A study originally intended to update the taxonomy and distribution of calanoid copepods in selected freshwater ecosystems of Central Luzon has led to the discovery of a new record of Phyllodiaptomus Kiefer, 1936 in Candaba Swamp, Pampanga. Since 1979, the only calanoid copepods recorded from this area included Filipinodiaptomus insulanus (Wright S., 1928) and Tropodiaptomus australis Kiefer, 1936. Later studies on calanoid copepods in the region have since been non-existent. Analyses of pertinent key morphological characters revealed that the specimens at hand belonged to Phyllodiaptomus (Ctenodiaptomus) praedictus sulawensis Alekseev & Vaillant, 2013, a freshwater diaptomid calanoid copepod subspecies discovered and known to be endemic only in Indonesia. Provided in this paper are baseline information on the morphological characters of the Philippine members of the subspecies accompanied by line drawings as well as a comparison between the recorded morphological data presented by Alekseev, Haffner, Vaillant & Yusoff (2013) and the current dataset to support the identification of the specimen. The discovery of P. (C.) praedictus sulawensis in the Philippines, which was thought to be endemic in Indonesia, presents a new record of this species in the country and the first such record outside of its country of origin.

The Sarcoplasmic Reticulum of Striated Muscle of A
THE SARCOPLASMIC RETICULUM OF STRIATED MUSCLE OF A CYCLOPOID COPEPOD WOLF H. FAHRENBACH, Ph.D. From the Department of Anatomy, Harvard Medical School, Boston ABSTRACT The fine structure of the abdominal musculature of the copepod Macrocyclops albidus was investigated by electron microscopy. Tubules penetrate into the muscle fibers from the sarcolemma, continuity between the wall of the tubules and the sarcolemma being clear. A dense network of tubules envelops the myofibrils, its interstices being occupied by cisternal elements. At the Z lines the tubules traverse the interior of myofibrils, giving off branches which course longitudinally within the substance of the myofibrils. These branches are also accompanied by elongate, non-intercommunicating cisternae. Comparison of this fast acting copepod muscle with other vertebrate and invertebrate muscles indicates that the complexity of the tubular system is a function of the myofibrillar geometry, whereas the degree of development of the cisternal system is related to the contraction speed of the muscle. INTRODUCTION The copepod Macrocyclops albidus (Jurine) 1820 internal architecture of these muscles, which (Arthropoda, Crustacea) is one of the most com- were used because of the greater ease of orienta- mon North American copepods.

Diversity and distribution of the free-living freshwater Cyclopoida (Copepoda: Crustacea) in the Neotropics Silva, WM.* Departamento Ciências do Ambiente, Campus Pantanal, Universidade Federal de Mato Grosso do Sul – UFMS, Av. Rio Branco, 1270, CEP 79304-020, Corumbá, MS, Brazil *e-mail: [email protected] Received March 26, 2008 – Accepted March 26, 2008 – Distributed November 30, 2008 (With 1 figure) Abstract Cyclopoida species from the Neotropics are listed and their distributions are commented. The results showed 148 spe- cies in the Neotropics, where 83 species were recorded in the northern region (above upon Equator) and 110 species in the southern region (below the Equator). Species richness and endemism are related more to the number of specialists than to environmental complexity. New researcher should be made on to the Copepod taxonomy and the and new skills utilized to solve the main questions on the true distributions and Cyclopoida diversity patterns in the Neotropics. Keywords: Cyclopoida diversity, Copepoda, Neotropics, Americas, latitudinal distribution.

Os resultados mostram um número de 148 espécies, sendo que 83 espécies registradas na Região Norte (acima da linha do Equador) e 110 na Região Sul (abaixo da linha do Equador). A riqueza de espécies e o endemismo estiveram relacionados mais com o número de especialistas do que com a complexidade ambiental. Novos especialistas devem ser formados em taxo- nomia de Copepoda e utilizar novas ferramentas para resolver as questões sobre a real distribuição e os padrões de diversidade dos Copepoda Cyclopoida nos Neotrópicos. -
Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans
Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans by Robert George Young A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Robert George Young, March, 2016 ABSTRACT MOLECULAR SPECIES DELIMITATION AND BIOGEOGRAPHY OF CANADIAN MARINE PLANKTONIC CRUSTACEANS Robert George Young Advisors: University of Guelph, 2016 Dr. Sarah Adamowicz Dr. Cathryn Abbott Zooplankton are a major component of the marine environment in both diversity and biomass and are a crucial source of nutrients for organisms at higher trophic levels. Unfortunately, marine zooplankton biodiversity is not well known because of difficult morphological identifications and lack of taxonomic experts for many groups. In addition, the large taxonomic diversity present in plankton and low sampling coverage pose challenges in obtaining a better understanding of true zooplankton diversity. Molecular identification tools, like DNA barcoding, have been successfully used to identify marine planktonic specimens to a species. However, the behaviour of methods for specimen identification and species delimitation remain untested for taxonomically diverse and widely-distributed marine zooplanktonic groups. Using Canadian marine planktonic crustacean collections, I generated a multi-gene data set including COI-5P and 18S-V4 molecular markers of morphologically-identified Copepoda and Thecostraca (Multicrustacea: Hexanauplia) species. I used this data set to assess generalities in the genetic divergence patterns and to determine if a barcode gap exists separating interspecific and intraspecific molecular divergences, which can reliably delimit specimens into species. I then used this information to evaluate the North Pacific, Arctic, and North Atlantic biogeography of marine Calanoida (Hexanauplia: Copepoda) plankton. -

The study of small water bodies contributes to understanding aquatic organisms’ adaptation to sharp fluctuations in external factors. Studies of biological com- munities’ response to fluctuations in external factors can be used for bioindication of the ecological state of small water bodies. In this regard, the purpose of the research is to study the structure of zooplankton of small lakes in South-East Kazakhstan in connection with various physicochemical parameters to understand the role of biological variables in assessing the ecological state of aquatic Citation: Aubakirova, M.; Krupa, E.; ecosystems.
