Abstract:
The present paper aims to describe the spatial distribution of zooplankton copepods, their biomass and instantaneous secondary production, in Barra Bonita, a large eutrophic, polymitic reservoir (22° 29' S and 48° 34' W) on the Tietê River, of the Paraná basin. Sampling was carried out during two seasons: dry winter and rainy summer. Species composition, age structure and numerical density of each copepod species population were analyzed at 25 sampling stations. Secondary production was calculated for Copepoda, the dominant group in zooplankton communities, taking Calanoida and Cyclopoida separately. Copepoda represented the largest portion of the total zooplankton biomass, the dominant species being Notodiaptomus iheringi among the Calanoida and Mesocyclops ogunnus and Thermocyclops decipiens among the Cyclopoida. The production of Copepoda was higher during the rainy summer (23.61 mgDW.m-3.d-1 in January 1995) than during the dry winter season (14 mgDW.m-3.d-1 in August 1995), following the general pattern of abundance for the whole zooplankton community. Among the copepods, Cyclopoida production was higher than that of Calanoida, a pattern commonly observed for tropical lakes and reservoirs. Barra Bonita copepods are very productive, but there was a great degree of spatial heterogeneity, related to the physical and chemical conditions, particularly the level of nutrients and also to phytoplankton biomass.

Abstract:
Calanoida have the highest number of species among Copepoda in marine plankton, but not in fresh water, where the greatest number are Cyclopoida. Freshwater Cyclopoida also live in more freshwater sites than Calanoida. This could be a consequence of an invasion of freshwater by marine Cyclopoida before Calanoida. Similar to Cyclopoida, but different from marine Calanoida, freshwater Calanoida females produce egg sacs and care for eggs. This strategy is common among all freshwater plankton, suggesting that the evolution of parental care is an obliged adaption to conquer fresh water. Calanoida, different from Cyclopoida, survive adverse conditions as resting eggs. This life-cycle constraint obliges eggs to survive their mother’s death and wait in the benthos for a certain period. The necessity of completing embryonic development and the hatching of eggs far from the mother’s protection may be responsible for the relatively lower evolutionary success of Calanoida in fresh water compared to Cyclopoida (which rest as juveniles, thus protecting eggs in any moment of their development). Therefore, the brooding of eggs appears to be the obliged solution for Calanoida’s final establishment in fresh water, but the dispersion of eggs on the bottom after the mother’s death and during the rest period is probably the weak point in Calanoida’s competition with Cyclopoida.

Abstract:
Copepoda adalah golongan crustacean yang dapat dijadikan sebagai pakan alami untuk larva ikan. Secara umum copepoda tergolong dalam empat ordo yaitu Calanoida, Cyclopoida, Harpacticoida, dan Monstrilidae. Di Balai Besar Riset Perikanan Budidaya Laut, Gondol, Copepoda yang dibudidayakan adalah jenis Harpacticoida yaitu Tisbe sp. yang pemeliharaannya dikerjakan dalam bak terkontrol. Copepod ini diberi pakan berupa fitoplankton, scoot’s emulsion, pelet ikan, dan ragi, serta sedikit penambahan probiotik. Pembatas selama budidaya adalah sulitnya produksi naupli copepoda secara massal, hal ini dikarenakan waktu bertelur yang tidak seragam antara individu copepoda, sehingga tidak bisa ditentukan waktu yang tepat untuk panen nauplii secara besarbesaran. Pembatas kedua adalah lambatnya reproduksi copepoda yaitu 14 hari jika dibandingkan dengan rotifer yang hanya dua hari. Pembatas ketiga adalah adanya spesies asing atau predator yang menyerang copepoda pada kondisi tertentu, seperti tingginya nutrisi pakan pada bak pemeliharaan.

Abstract:
AIM: Among the planktonic microcrustaceans, copepods Cyclopoida and Calanoida are the most representative groups, being the largest biomass of the plankton community. The aim of this work is to catalogue and analyze the distribution of copepod species (Crustacea, Maxillopoda) in pelagic and littoral zones from small reservoirs in the northwest of the São Paulo State, in dry and rainy seasons (2007 and 2009). METHODS: Zooplankton samplings were carried out in littoral and pelagic zones of 13 small shallow reservoirs (mean depth: 2.6 m) using vertical hauls and plankton net (45 µm). Water physical and chemical parameters were also monitored with a multiparameter Horiba® U10. RESULTS: Eighteen species of copepods were identified, 13 Cyclopoida and 5 Calanoida. There was no statistical difference between the distributions of species from the littoral and pelagic zones and neither between dry and rainy seasons. Three species occurred exclusively in the littoral zone - Eucyclops elegans, Paracyclops chiltoni and Mesocyclops ogunnus. Tropocyclops prasinus and Thermocyclops decipiens were the most frequent species in the studied environments. CONCLUSION: Our data suggest that in shallow reservoirs copepods present a homogeneous distribution between the littoral and pelagic zones and Cyclopoida are more diverse than Calanoida. Shallow depths and eutrophic state may be regarded as limiting conditions for the development of Calanoida in these reservoirs.

Abstract:
Abstract Coastal Lake Bardawil (Egypt) is one of the largest hypersaline lakes in the world. In 2009–2010, the authors studied composition, distribution and seasonal dynamics of copepods at 12 sites. A total of 10 species of copepods were recorded in zooplankton during the study period, including 5 Calanoida, 2 Cyclopoida and 3 Harpacticoida. Oithona nana was the most common and most abundant species. All copepods in the lake can be divided into three groups: 1) planktic species that form stable populations, 2) species of Mediterranean plankton incidentally entering the lake from the adjacent sea area, 3) benthic Cyclopoida and Harpacticoida that can be abundant in plankton. Two species – Acartia tonsa and A. danae were recorded here for the first time. The total abundance of copepods in the lake was significantly higher (90 times on average) compared to that observed in 2008–2009 in the waters of the Egyptian Mediterranean Sea. Since 1967, the complex of common and dominant copepod species in the lake has changed significantly. The total average annual copepod abundance varied: in 2002 – it was about 4000 ind. m−3, in 2004 – 152 000 ind. m−3, in 2005 – about 25 300 ind. m−3, and in 2009–2010 – about 56 000 ind. m−3.

Abstract:
Three new species of copepod crustaceans are described from material collected from anchialine and brackish habitats inand around the village of Walengkabola on the coast of Muna Island, to the southeast of Sulawesi. A new species of cy-clopoid, Paracyclopina sacklerae n. sp., was described from material collected from the tidal inflow entering into the bot-tom of sinkholes a few metres inland from the shoreline. Detailed comparisons are made with Paracyclopina orientalis(Lindberg, 1941), n. comb., a closely related congener here transferred from its original genus Cyclopetta Sars, 1913. Theassignment of Paracyclopina Smirnov, 1935 to the family Cyclopettidae is followed here despite uncertainty over the va-lidity of some of the families created by the break up of the former Cyclopinidae. Two new species of Boholina Fosshagen& Iliffe, 1989 are described, based on material from the same sinkholes and from caves located up to 700m inland fromthe coast and exhibiting further reduced salinity down to 1.8 ppt. One species, B. parapurgata n. sp., is very closely relatedto B. purgata Fosshagen & Iliffe, 1989 from Bohol island in the Philippines, the other B. munaensis n. sp., is very closelyrelated to B. crassicephala Fosshagen & Iliffe, 1989 also from Bohol island, but a number of fine scale differences in the leg 5 of both sexes are recognised in each case. Keys to valid species of both genera are provided.

Abstract:
The present work is aimed at discovering the diversity and abundance of copepods in the zooplankton community on the north coast of Angola, during the hot season 2014-2016. The samples were collected during the research cruise on board the Norwegian research ship “Dr. Fridtjof Nansen” in February - March on the Congo River and Luanda monitoring lines. Zooplankton sampling was performed using a multinet net in an oblique trawl (2014) and a WP2 net in a vertical trawl (2015 and 2016), both with 180 µm mesh. The samples were fixed in 4% formaldehyde and analyzed in the oceanography laboratory of the National Institute of Fisheries and Maritime Research in Angola. In the three years of sampling, copepods were present in the zooplankton community. The diversity of copepods on the northern Angolan coast, from 2014 to 2016 in the hot season, included 27 genera corresponding to 19 families. The Copepoda class was the most abundant group in the zooplankton community, corresponding to more than 80% of the abundance, having been represented by the orders Calanoida, Cyclopoida and Harpacticoida.

Abstract:
Este projeto de pesquisa foi desenvolvido nos reservatórios e tributários do Médio e Baixo rio Tietê, São Paulo, com o objetivo de avaliar a composição, distribuição e densidade das espécies de Copepoda Calanoida e Cyclopoida e sua relação com a disposição dos reservatórios construídos em série (cascata), os quais apresentam diferenças na morfometria, período e área de inundação, grau de trofia (relacionando aos usos e ocupação da bacia hidrográfica), vazão e tempo de residência da água. Para tanto, foram realizadas coletas nos reservatórios e tributários nos meses de fevereiro, maio, julho e outubro/2000, quantificando as principais variáveis físicas, químicas e biológicas, além da análise qualitativa e quantitativa do zooplâncton, com ênfase em Copepoda Calanoida e Cyclopoida. Os resultados demonstram que apesar de ser verificada a melhoria da qualidade da água nos reservatórios a jusante, ainda ocorrem contribuições pontuais via tributários e difusas pelas atividades desenvolvidas na bacia hidrográfica, aumentando a concentração das formas nitrogenadas e fosfatadas, influenciando diretamente nas condições tróficas dos reservatórios e, conseqüentemente, na composição, densidade e distribuição das populações planctônicas. Os reservatórios classificam-se como eutróficos ou mesotróficos (dependendo da sua localização no rio Tietê e da sazonalidade) e os rios como eutróficos, principalmente em decorrência das elevadas concentrações de fósforo e clorofila.Em relação à comunidade zooplanctônica, os Copepoda e Rotifera foram mais abundantes, com uma variação espacial e sazonal relacionada às condições tróficas e temperatura, bem como aos mecanismos diferenciados do controle operacional das barragens (vazão e tempo de residência da água). As espécies de Copepoda encontradas no sistema foram Notodiaptomus iheringi, Notodiaptomus evaldus, Notodiaptomus deitersi, Argyrodiaptomus azevedoi Thermocyclops decipiens, ) Thermocyclops minutus, Thermocyclops inversus, Mesocyclops longisetus, Mesocyclops brasilianus, Mesocyclops meridianus, Mesocyclops ogunus, Acanthocyclops ogunus e Paracyclops chiltoni, sendo N. iheringi, N. evaldus, T. decipiens e T. minutus as espécies dominantes, com diferenças na distribuição e abundância em função dos locais de amostragem (tributários ou reservatórios) e período de coleta (sazonalidade).
This research project was developed in Tietê River reservoirs and tributaries, São Paulo, Brazil, aiming to evaluate the composition, distribution and density of Copepoda Calanoida and Cyclopoida species and its relationship with reservoirs disposition in Tietê River, built in series (cascade), which present differences in morphometry, flood period and area, trophic level (related to the hydrographic basin uses and occupation), discharge and water residence time. For that, collections were accomplished in reservoirs and tributaries on February, May, July and October/2000, quantifying the main physical, chemical and biological variables, besides qualitative and quantitative zooplankton analysis, with emphasis in Copepoda Calanoida and Cyclopoida. Results demonstrate that, in spite of the improvement of water quality verified downstream reservoirs, it still happen punctual tributary contributions, diffused due to activities developed in the hydrographic basin, increasing nitrogenous and phosphate forms concentration, influencing directly the reservoir trophic conditions and, consequently, composition of species, density and distribution. Reservoirs are classified as eutrophic or mesotrophic (depending on its location in Tietê River and sazonality) and the rivers as eutrophic, due mainly to the high phosphorus and chlorophyll concentrations. In relation to the zooplankton community, Copepoda and Rotifera were the most abundant, with spacial and seasonal variationrelated to trophic conditions and temperature, as well as to the barrier differentiated operational control mechanisms (discharge and water residence time). The Copepoda species found in the system were Notodiaptomus iheringi, Notodiaptomus evaldus, Notodiaptomus deitersi, Argyrodiaptomus azevedoi, Thermocyclops decipiens, Thermocyclops minutus, Thermocyclops inversus, Mesocyclops longisetus, Mesocyclops brasilianus, Mesocyclops meridianus, Mesocyclops ogunus, Acanthocyclops ogunus and Paracyclops chiltoni; being N. iheringi, N. evaldus, T. decipiens and T. minutus the dominant species, with differences in the distribution and abundance in function of the sampling places (tributaries or reservoirs) and collection period (sazonality).

Abstract:
Copepods, minute crustaceans, are vital constituents of marine food web dynamics in tropical ecosystems. Ecologically, copepods provide the link between primary production and tertiary consumers. Changes in population structure and densities may impact ecosystem stability and production on small to large spatial scales. The present study examined the influence of the Florida Current on copepod population densities off the coast of Fort Lauderdale, Florida due to limited data in the area. Samples were collected during February and July 2007 at two locations, Stations A and B. Station A, dependent on current dynamics, fluctuated between the most western boundary and the inshore waters adjacent to the coast. Station B was typically located within the Florida Current showing great influence from the current’s physical factors. The current, acted as a physical barrier, entrapping species at near shore stations, increasing population densities by increased nutrient loads through upwelling and land runoff. The movement of the current inshore showed a greater resurgence of oceanic species at each station. However, the western edge of the current, acting as a barrier, yielded the lowest population densities overall and among all copepod orders. The decrease can influence food web dynamics and the prey availability to higher tertiary consumers. Population dynamics were ascertained by relative copepod densities identified to the lowest possible taxa and enumerated. Calanoid copepods were dominant in zooplankton samples, showing high instances of Calanus and Undinula, followed by Poecilostomatoida, highly represented by Corycaeus and Oncaea, and Cyclopoida. Poecilostomatoid densities were numerically important, where in some samples Corycaeus contributed to 42 % of overall copepod densities. Previous studies have led to their underestimation, due to gear selectivity and extrusion directly related to their prosome length. Diversity levels revealed an overall diverse habitat, typical of tropical environments. However, there was greater diversity in coastal waters as compared to the Florida Current which was only found oceanic species present.

Redescription of one rare species of Diaptomidae - Odontodiaptomus thomseni; 3. Basic ecological attributes of planktonic cyclopoid and calanoid copepods of ―La Plata‖ River Basin; and 4. Boundaries of geographic distribution of Diaptomidae in ―La Plata‖ Basin, with synthesis of historic and current processes. In the guide of identification are presented keys of identification, taxonomic diagnosis, general commentaries, illustrations, scan electron microscopy images of 37 species, for cyclopoids females and calanoids males. In chapter one, species with incertae status were not included. For ecological attributes in chapter three, the number of species included in richness and diversity calculations was higher, and the results points to major richness in the middle and low stretches of Parana River, in summer and winter, respectively. Finally, in chapter four, the evolution tendencies of Diaptominae are discussed, which point to high endemism patterns for many species, suggesting an ancient evolution processes after Cretaceous separation of the continents, when the Brazilian shield was used as refuge along the time until the current fauna status

Abstract:
Production and recruitment measurements in marine copepods of the genus Calanus have been addressed via the study of genes involved in early embryogenesis. The first sequence from a Calanus helgolandicus (C. helgolandicus) developmental gene (Cal-Antp) has been cloned by screening a C. helgolandicus genomic library with a homologous Calanus homeobox probe. Sequencing of an isolated and sub-cloned fragment of this gene, plus further analysis by Inverse Polymerase Chain Reaction (IVPCR), has shown it to be homologous with other Antennapedia homeobox genes. The temporal expression of Cal-Antp was analysed through its messenger RNA (mRNA) complement by Reverse Transcription Polymerase Chain Reaction (RT-PCR). The gene was expressed in tissue taken from eggs over 18 hours old, and in nauplii and copepodite stages, but no expression was detected in eggs less than 18 hours old or adult tissue. Three further homeobox-containing genes have been identified and analysed through their expression in C. helgolandicus eggs. Two of these are caudal homologues, and the third is homologous to the Antennapedia class of genes. The C. helgolandicus developmental gene sequence data provides a means of developing probes to monitor the temporal expression of such genes and their responses to environmental influence. The applicability of such probes to the investigation of key production and recruitment processes, including egg viability measurement, is discussed. A relatively simple and cost effective method has been developed to identify the four Calanus species common to the North Atlantic. This system involves the PCR amplification of a region of the mitochondrial rRNA gene without prior purification of the DNA, followed by Restriction Fragment Length Polymorphism (RFLP) analysis of the amplified product. The versatility of the method is demonstrated by the unambiguous identification to species of any life stage, from egg to adult, and of any individual body parts. The molecular identification technique has for the first time shown the unexpected presence of three different Calanus species in Lurefjorden, Norway and has proved to be consistently accurate for all individuals tested including geographically distinct conspecific populations.

The zooplankton community plays an important role in the dynamics of aquatic ecosystems, especially in the energy flow and nutrient cycling. The density, the biomass, the taxonomic composition and the body size of these group are variables that can characterize in limnological terms a water body and can indicate the deterioration degree of the environment, as well the eutrophication levels of the system. The Jaguari and Jacareí reservoirs are located on the Cantareira system, one of the largest water producers systems in the world; nevertheless in recent decades the quality of the water has been altered due to human pressure, the reason why we sought to evaluate it according to the zooplankton structural variations. A sampling of this community, as well the gathering of physical and chemical water data, were performed on eight points, with taxonomic identification, the numerical count of the groups, the biomass and body size determination and the calculation of two biological indicator indices. The results obtained and analyzed in this study enable to characterize the Jaguari and Jacareí reservoirs as heterogeneous environments, the Jaguari predominantly eutrophic and the Jacareí oligotrophic. There was a relationship between the trophic states and the structure of the community for both samplings, as well as between Calanoida/Cyclopoida ratio and k-dominance curves with the levels of disturbance observed in the reservoirs by the constant supply of nutrients of Jaguari river. The biomass values and the body size structure of all species of the groups Cladocera and Copepoda were strongly associated with the trophy degree of both reservoirs. In reservoir Jaguari, the increasing of TSI was indicated by the increased nutrient concentrations and higher values of dominance and lower values of evenness and Shannon-Wiener index; for the Jacarei reservoir the lower trophic status and changes in the structure community, as evidenced by indicators indices and other variables, were less pronounced. Zooplankton community properties as indicators of reservoir trophic state are indeed adequate tools.
A comunidade zooplanctônica desempenha um papel importante na dinâmica dos ecossistemas aquáticos, especialmente no fluxo de energia e ciclagem de nutrientes. A densidade, a biomassa, a composição taxonômica e o tamanho corpóreo deste grupo são variáveis que podem caracterizar limnologicamente um corpo de água e podem indicar o grau de deterioração do ambiente, bem como os níveis de eutrofização do sistema. Os reservatórios Jaguari e Jacareí são localizados no sistema Cantareira, um dos maiores sistemas produtores de água do mundo; no entanto, nas últimas décadas a qualidade da água foi alterada devido à grande pressão antrópica, motivo pelo qual buscamos avaliá-la de acordo com variações estruturais do zooplâncton. A amostragem desta comunidade, assim como a coleta dos dados físicos e químicos da água, foram realizadas em oito pontos, com a identificação taxonômica, a contagem numérica dos grupos, a determinação da biomassa e do tamanho corpóreo das espécies e o cálculo de dois índices biológicos indicadores. Os resultados obtidos e analisados no presente trabalho permitem caracterizar os reservatórios Jaguari e Jacareí como ambientes heterogêneos, sendo o Jaguari predominantemente eutrófico e o Jacareí oligotrófico. Observou-se relação entre os estados tróficos e a estrutura da comunidade para ambas as coletas, bem como entre a razão Calanoida/Cyclopoida e as curvas de k-dominância com os níveis de perturbação observados nos reservatórios pelo aporte constante de nutrientes do Rio Jaguari. Os valores de biomassa e a estrutura em tamanho corpóreo de todas as espécies dos grupos Cladocera e Copepoda estiveram fortemente relacionados com o grau de trofia de ambos os reservatórios. No reservatório do Jaguari, o aumento do IET foi indicado pelo aumento da concentração de nutrientes e por maiores valores de dominância e menores valores de equitatividade e do Índice de Shannon- Wiener; para o reservatório Jacareí o estado trófico foi menor e as alterações na estrutura da comunidade, como evidenciado pelos índices indicadores e demais variáveis, foram menos pronunciadas. As propriedades da comunidade zooplanctônica como indicadores do estado trófico dos reservatórios se mostraram ferramentas adequadas.

Abstract:
Os Copepoda constituem a maior classe de pequenos crustáceos, com mais de 8.500 espécies descritas. Dentre as cinco ordens de Copepoda de vida livre, as espécies pertencentes à ordem Calanoida apresentam um forte endemismo, com uma restrita distribuição geográfica. Além disso, os Copepoda Calanoida são particularmente sensíveis a contaminantes contidos na coluna de água devido ao seu hábito planctônico. No presente trabalho foram realizados estudos ecotoxicológicos com duas espécies de Copepoda Calanoida, particularmente com as espécies Argyrodiaptomus furcatus Sars, 1901 e Notodiaptomus iheringi Wright, 1935. Estas espécies foram comparadas com relação à sensibilidade e desempenho como organismos-teste na avaliação da qualidade da água em ecossistemas de água doce. Foram testadas e adaptadas metodologias de cultivo em laboratório, e foram estudados os principais aspectos da biologia destes em condições ambientais controladas. Além disso, foram analisados aspectos referentes à dinâmica populacional. A sensibilidade das duas espécies de Calanoida às substâncias de referência sódio, potássio e zinco na forma de cloreto (\'NA\'CL\', \'K\'CL\' e \'ZN\'CL IND.2\', respectivamente), ao dicromato de potássio (\'K IND.2\'CR IND.2\'O IND.7\') e ao sulfato de alumínio (\'AL IND.2\'(\'SO IND.4\')IND.3\'), aos surfactantes dodecilsulfato de sódio (\'C IND.12\'H IND.25\'NA\'O IND.4\'S\') e ácido dodecil benzenosulfonato de sódio (\'CH IND.3\'(\'CH IND.2\')IND.11\'C IND.6\'H IND.4\'S\'O IND.3\'NA\'), foram avaliadas. Além disso, avaliou-se a toxicidade aguda de diferentes amostras ambientais e das toxinas da cianobactéria Microcystis aeruginosa após tratamento por irradiação. Os resultados dos testes ecotoxicológicos foram expressos em concentração efetiva (CE(I)50). Para o cálculo estatístico da CE50 foi utilizado o programa Trimmed Spearman-Karber. Os resultados relativos ao ciclo de vida mostraram que N. iheringi tem um menor tempo de desenvolvimento do que A. furcatus, com tempos de duração do desenvolvimento do ovo determinados pelos métodos indireto e direto. Verificou-se que a espécie de N. iheringi, de menor tamanho, apresentou tempo de desenvolvimento pós-embrionário menor do que a espécie de maior tamanho, A. furcatus. As taxas intrínsecas de crescimento populacional foram mais elevadas para a espécie A. furcatus do que para N. iheringi. Pelos resultados obtidos observou-se que N. iheringi além de atingir tamanhos menores, possui um desenvolvimento mais rápido e ciclo de vida mais curto. Em relação à sensibilidade destes Copepoda Calanoida às substâncias tóxicas observou-se que em relação aos sais, estas duas espécies foram mais sensíveis ao cloreto de potássio (\'K\'CL\'). Em relação aos metais, o grau de toxicidade aos Copepoda decresceu na sequência zinco > cromo > alumínio. Já com em relação aos surfactantes, a espécie N. iheringi foi mais sensível do que A. furcatus, e a toxicidade diminui à medida que o estágio de desenvolvimento dos indivíduos se torna mais avançado. Os náuplios são mais sensíveis à maioria das substâncias de referência testadas (sais, surfactantes, cromo e zinco) do que os estágios de desenvolvimento mais avançados. A espécie N. iheringi é mais sensível aos diversos agentes tóxicos do que a espécie A. furcatus, no entanto, N. iheringi foi mais resistente às cianotoxinas do que A. furcatus. Os resultados apresentados corroboram a idéia de que os calanoides A. furcatus e N. iheringi apresentam elevada sensibilidade a uma variedade de substâncias tóxicas de referência, o que torna viável sua utilização como organismos-teste em ensaios ecotoxicológicos. Estes estudos podem proporcionar maior entendimento sobre a estrutura das comunidades aquáticas e das alterações na dinâmica das populações, no sentido de se poder verificar como as espécies respondem às alterações na qualidade da água e o porquê das modificações na estrutura das comunidades, permitindo, dessa forma, ações de manejo e de conservação visando a preservação da biodiversidade das águas doces.
Copepods constitute the largest class of small crustaceans, with more than 8,500 described species. Among the five orders of free-living copepods, the species belonging to the order Calanoida show strong endemism, with a restricted geographic distribution. Additionally, they are particularly sensitive to contaminants in the water column due to their planktonic habit. In the present study ecotoxicological studies with two species of Calanoida copepods were performed, particularly with the species Argyrodiaptomus furcatus Sars, 1901 and Notodiaptomus iheringi Wright, 1935. These species were compared for sensitivity and performance as test organisms in assessing water quality in freshwater ecosystems. Methods of cultivation in the laboratory were tested and adapted, and the main aspects of these species biology were studied under controlled temperature and photoperiod. In addition, aspects related to population dynamics were also analyzed. The sensitivity of the calanoids to a number of reference substances as: sodium, potassium and zinc in the form of chlorides (\'NA\'CL\', \'K\'CL\' and \'ZN\'CL IND.2\', respectively), potassium dichromate (\'K IND.2\'CR IND.2\'O IND.7\') and aluminum sulfate (\'AL IND.2\'(\'SO IND.4\')IND.3\'), and to the surfactant sodium dodecyl sulfate (\'C IND.12\'H IND.25\'NA\'O IND.4\'S\') and sodium dodecyl benzenesulphonate (\'CH IND.3\'(\'CH IND.2\')IND.11\'C IND.6\'H IND.4\'SO IND.3\'NA\') were evaluated. Also the toxicity of environmental samples and of the cyanobacteria Microcystis aeruginosa toxin after irradiation treatment was tested. The results of ecotoxicity tests were expressed as effective concentrations (EC(I)50). The statistical calculation of the EC50 was carried out by the Trimmed Spearman-Karber program. The results regarding the copepods life cycle showed that N. iheringi has a shorter development time and duration of egg development, by both indirect and direct methods, than A. furcatus. It was found that small sized N. iheringi, had a post-embryonic development faster than the larger species, A. furcatus. The intrinsic rates of population increase were higher for the species A. furcatus than for N. iheringi. The results indicated that N. iheringi besides reaching smaller sizes, has a faster development and shorter life cycle. Regarding the sensitivity of these two species to toxic substances it was observed that in relation to the salts the calanoids were more sensitive to the potassium chloride (\'K\'CL\'). Compared to metals, toxicity to copepods followed the sequence zinc> chromium> aluminum. However, regarding surfactants the species N. iheringi was more sensitive than A. furcatus, and toxicity decreased with the advance in developmental stages. The nauplii were more sensitive to most of the reference substances tested (salts, surfactants, chromium and zinc) than the more advanced developmental stages. The species N. iheringi was more sensitive to various toxic agents than A. furcatus, but N. iheringi was more resistant to the cyanotoxins than A. furcatus. The results support the hypothesis that the calanoid copepods A. furcatus and N. iheringi have high sensitivity to a variety of toxic reference substances, what makes them feasible to be used as test organisms in ecotoxicological tests. The study performed may provide further understanding about the structure of aquatic communities and changes in population dynamics, contributing for the understanding of how species respond to changes in water quality by changes in community structure, subsidizing management actions aiming the conservation of freshwater biodiversity.
