In search of standardisation: A comparison of toxicity bioassays on two marine crustaceans (Palaemon serratus and Tigriopus brevicornis).
Provedor de dados: 5
Autores: Le Dean, Loic; Devineau, J.
In order to mitigate the insufficiency of the number of currently available toxicity tests in marine middle, two studies on the effects of cadmium and zinc were carried through with two marine crustaceans: the prawn Palaemon serratus and a copepoda Tigriopus brevicornis. The comparison of methodologies (rearing conditions - experimental procedure) and results obtained allowed to show the advantages and the disadvantages of these two tests in order to consider a standardization.

Nutrition chez des copepodes en milieu lagunaire mediterraneen en fonction de la concentration en particules et de la temperature
Provedor de dados: 5
Autores: Gaudy, R; Pagano, M.
The zooplankton of an eutrophic brackish lagoon (Etang de Berre), near Marseille (France) was studied during an annual cycle. It was characterized by large populations of a pelagic copepod (Acartia tonsa ). Grazing on natural particles by this species was investigated. Adults were able to use an extended range of particle sizes, but showed selectivity for particles concentration was observed (14 mu m). Temperature and particles concentration appear to modify the selectivity behavior. Juvenile stages could also catch particles of various size but did not show the same selectivity for the peak particles as adults. Daily food ration was high comparatively to open-sea copepods. Taking into account several results obtained on food ration, egg production and...

Biochemical substrates expenses and respiration at short-term starvation of marine planktonic animals
Provedor de dados: 5
Autores: Pavlova, Z; Morozova, A; Gaudy, R; Shchepkin, V.
One of the most important indices at estimation of productivity characteristics of hydrobionts is oxygen consumed in the process of respiration. Usually respiration (standard metabolism) is measured in small-volume respirometres (30-50 ml) where animals' activity is considerably restricted. It may underestimate respiration in comparison to natural one. Therefore respirometres of larger volume were used. Simultaneously under same conditions we tried to estimate energy requirements by expense of main biochemical components of organic matter (lipids, protein, glycogen). Results were used to calculate energy budget and to compare energy expenditures, measured according to consumed oxygen and tissue substrates expense.

New way to estimate efficient use of energy in copepods during migrations
Provedor de dados: 5
Autores: Petipa, T; Ostrovskaya, N.
It is shown that the energy expenditures on the mechanical movements of copepods depend on the knowledge of character of velocity movements range at active phase. The method of direct estimates of energy expenditures for copepod vertical migration permits to determine more real coefficients of chemical energy utilization on the mechanical work.

Role de Sprattus sprattus (Linne, 1758) dans l'utilisation du zooplancton des eaux Roumaines de la Mer Noire
Provedor de dados: 5
Autores: Porumb, Loan I.
Feeding of the S. sprattus was studied comparatively with the dynamics of the zooplanktonic trophic base. In April, the sprat consumed 1,459 t of zooplankton, especially Acartia clausi (84 per cent). Zooplanktonic productivity was 30 per cent due to Acartia clausi, and the sprat consumed 56 per cent of this copepod production. In April, the wt growth of the sprat was 115 t. In May, the sprat consumed 6.201 t of zooplankton, that resulted in a fish production of 492 t. A clausi contributed 36.41 per cent to the zooplankton production and the sprat fed on copepods at a level of 93 per cent. In June, only 1,094 t of zooplankton resulted in a fish production of 87 t. Zooplanktonic production was 60 per cent due to A. clausi, and only 12 per cent of this was...

Production de chitine par les crustaces du zooplancton de la baie de Calvi (Corse)
Provedor de dados: 5
Autores: Gervasi, E; Jeuniaux, C; Dauby, P.
Chitin was estimated in samples of planktonic crustaceans living in Calvi Bay (Corsica). The percentages of chitin, with respect to dry weight, are comprised between 3.10% in Clausocalanus spp. and 12.22% in Cladocera (mainly Evadne ). The percentage of chitin remained approximatively constant during larval development in Calanus helgolandicus (3.26%). Using these results and the values of total biomass and production estimated by Dauby (1985) at the same place during a complete annual cycle (1983-1984), chitin biomass and production were calculated for every planktonic crustacean species (or group of species) and for the whole crustacean plankton. Daily chitin production was maximum during May (20.06 mg.m super(-2)/d). As far as the whole year is...

Peculiarities of reproduction and generative production of tropical copepods
Provedor de dados: 5
Autores: Sazhina, L.
The aim of the present investigation consisted in revealing the regular natural changes of fecundity in mass pelagic copepods of the World Ocean tropical zone. Particular emphasis was placed on determination of the clutch size, duration of development, rate of generative production formation at both organism and population levels, and connection of these processes with environmental conditions. The major difficulty lay in the fact that most mass species of tropical copepods are laying eggs immediately into water thus complicating the determination of quantitative characteristics of reproduction.

Biologie du copepode Lernaeenicus sprattae Sowerby, 1806) et ses actions pathogenes sur les populations de sardines des cotes du  Languedoc-Roussillon.
Provedor de dados: 5
Autores: El Gharbi, Salwa; Rousset, Viviane; Raibaut, André.
Lernaeenicus sprattae is a blood-feeding copepod parasite of the pilchard, Sardian pilchardus . The larval stages of L. sprattae attach to the skin or the fins of the larval fish when the fish enter the lagoons. The mature, and in some cases ovigerous females of L.sprattae seek out the base of the fins or directly implant in the eye of juvenile or adult pilchards. The copepod has a particularly serious  effect at the site of infection: its feeding has a severe effect on the fish. The pilchard returns to its breeding grounds in the open sea at the end of summer; this migration allows the copepod to complete its reproductive cycle and a new cycle of infestation is able to begin.

Laophontopsis Sars and the taxonomic concept of the Normanellinae (Copepoda: Harpacticoida): A revision
Provedor de dados: 16
Autores: Huys, Rony; Willems, Kris A.
The taxonomie concept of the subfamily Normanellinae Lang (Harpacticoida, Laophontidae) is revised. As a result a new family Laophontopsidae is proposed to accommodate Laophontopsis Sars and two new genera Aculeopsis and Telodocus. It is concluded that the presumed boreo-mediterranean distribution pattern displayed by the type species L. lamellifera (Claus) is merely the result of erroneous identifications. The population of northwest Europe is assigned to a new species L. borealis and another new species L. monardi is proposed for Monard’s (1928) material from Banyuls-sur-Mer. L. secundus Sewell is placed in the new genus Telodocus. Aculeopsis gen. nov. embraces only A. longisetosa spec. nov. and constitutes the most primitive genus of the family. The...

The cuticle of the chalimus II stage of Lepeophtheirus salmonis (Copepoda: Caligidae) comprised a four-layered epicuticle with a pronounced fuzzy coat which was separated from the outer and inner procuticles by a layer of transitional procuticle. The cuticle is underlain by a single-layered epidermis which overlies integumental glands and chromatophores. The structure of this cuticle is very similar to that described for free-living copepods and does not display the modifications associated with more highly transformed parasitic species.

Laophonte trispinosa Sewell is reported here from various localities in the Indian and the West Pacific Ocean, and is allocated to the herein erected genus Xanthilaophonte gen. nov. A second species, X. carcinicola spec. nov. is described from Indon »sia. The genus Xanthilaophonte gen. nov. is most closely related with Echinolaophonte Nicholls. Both species of this genus live in association with decapods, mainly Xanthidae, and occur on the carapax of their hosts, between the bristles. Comparison of the copepodid development clearly shows that the advanced morphology of Xanthilaophonte gen. nov. resulted from heterochrony events.

For a long time the identification of these two species were mixed up. Here, M. araucanus female is redescribed and the male described for the first time. A comparison is made with M. longisetus, whose male is also described for the first time. Detailed comparison between these two species shows that the following traits on specimens of both sexes can be used to separate the species: length/width ratio of caudal rami, ratio of terminal caudal setae, and length/width ratio of last segment of endopod of leg 4. Additional diagnostic characters for each sex are given. The geographic distributions of...

Three species of the genus Elaphoidella Chappuis, 1929 (Copepoda, Harpacticoida), from Montenegro are presented. E. uva n.sp., which belongs to the ‘gracilis’ group of species, is described from two subterranean localities in Montenegro, and is most closely related to E. bidens (Schmeil, 1894). E. phreatica (Chappuis, 1925) is reported from several localities, and new synonyms of this species are established. For E. denticulata Chappuis, 1929 this is the most western locality from which it has been recorded, and one new synonym of this species is established.

A new species of Cymbasoma (Copepoda: Monstrilloida) from the Sulu Sea, Philippines
Provedor de dados: 16
Autores: Suárez-Morales, E.
A specimen of a monstrilloid copepod collected by the U.S. Fisheries Steamer “Albatross“ in the Sulu Sea, west coast of Mindanao, Philippines, and deposited in the U.S. National Museum of Natural History, was taxonomically restudied. The specimen had been originally identified as a male of Monstrilla serricornis Sars by C.B. Wilson. Reexamination revealed that the specimen represents a new species of the genus Cymbasoma, C. mcalicei. This species can be distinguished by its body proportions and body size, but mainly by the structure of the genital lappets, which have a serrated posterior margin unique in the genus. This is the seventh species of Cymbasoma reported from East or Southeast Asia.

Autores: Vaupel Klein, J.C. von.
Two cases of apparent niche-partitioning and one case of alleged habitat-segregation in the calanoid copepod genus Euchirella are described. These are examined with regard to their possible implications for making generalizations about the structure of biocoenoses and about mechanisms of speciation in the pelagic marine environment.

Lovenula (Neolovenula) alluaudi (Guerne and Richard, 1890) in the Canary Islands (Copepoda: Calanoida: Paradiaptominae). Stygofauna of the Canary Islands, 19
Provedor de dados: 16
Autores: Bowman, Thomas E.
Lovenula (Neolovenula) alluaudi is widespread on Lanzarote, where it occurred at 22 of the 105 stations. On Fuerteventura it was found at only 2 of the 53 stations, both in the extreme northwest part of the island. It was also found in a reservoir on the south side of the small island of Alegranza. Samples collected at several hundred stations in the other Canary Islands failed to yield a single calanoid, supporting the belief that the eastern islands are fragments of the African continent that drifted to deeper waters. Males outnumbered females in about 2/3 of the samples, often heavily.

Moulting in the chalimus larva of the salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae)
Provedor de dados: 16
Autores: Bron, J.E.; Shinn, A.P.; Sommerville, C.
The ultrastructure of moulting in the chalimus phase of the parasitic caligid copepod Lepeophtheirus salmonis is described for the first time. The major features of the moult sequence correspond to those of other Crustacea, save for the absence of a distinguishable intermoult as defined by reduced epidermal activity and a cessation of cuticle production. This latter may be explained cither in terms of a continuous moulting process related to the constant food supply available to a parasite or in terms of a highly abbreviated intermoult period. The findings are discussed with respect to studies of other Crustacean species.

Conventional nebulisation ICPMS (Inductively Coupled Plasma Mass Spectrometry), was used to determine the concentration of a broad range of elements in the salmon louse Lepeophtheirus salmonis. Lice samples were collected from Atlantic salmon in seven localities (4 fish farms and 3 wild salmon fisheries) on two separate sampling occasions and prepared for analysis. Sixty six elements were measured, 35 of these were found to be variable and were subjected to univariate and multivariate statistical analysis. The results of the single element comparisons showed that not all individual sites could be discriminated from each other. Sea lice collected from cultured salmonids could be discriminated from those on wild salmonids at the same site using the elements...

Neocyclops (Protoneocyclops) ferrarii, a new species of cyclopid (Copepoda: Cyclopoida) from Belize, with remarks on the morphology of the genus Neocyclops
Provedor de dados: 16
Autores: Falavigna da Rocha, Carlos Eduardo.
Neocyclops (Protoneocyclops) ferrarii sp. n. is described from Candy’s Pond, Twin Cays, Belize. It is morphologically closest to N. (P.) wellsi Petkovski, 1986 from Mozambique and N. (P.) herbsti Petkovski, 1986 from the Red Sea. Pediger 1 in Neocyclops is distinct although reduced and often concealed beneath the cephalic shield. Specimens of Neocyclops (N.) vicinus and N. (N.) medius showed the same condition, warranting the supposition that the free pediger 1 is a consistent feature of the genus. The genital double somite bears a transverse cuticular thickening which apparently supports the seminal receptacle. The importance of the integumental pore patterns of the urosome and legs as useful taxonomic characters is pointed out.

Autores: Bell, S.; Bron, J.E.; Sommerville, C.
The morphology, function and distribution of exocrine glands of copepods have rarely been studied in detail and almost nothing is known about them in the sea lice species L. salmonis and C. elongatus. This study utilised a novel application of a light-microscopy staining technique to reveal a variety of glands m nauplius, copepodid, chalimus, preadult and adult stages. The stain, 3’,3-diaminobenzidine tetrahydrochloride (DAB), applied to fresh material, differentiated a population of exocrine glands and enabled a study of their distribution. The stain was successful in highlighting the ducts and pores associated with the larger glands. The locations of gland sub-populations were conserved in all life-stages, although glands in the swimming legs were found...

Precopulatory mate guarding and mating in Tachidius discipes (Copepoda: Harpacticoida)
Provedor de dados: 16
Autores: Dürbaum, Johannes.
Precopulatory mate guarding and mating behaviour of Tachidius discipes Giesbrecht, 1881, has been analysed using a video camera mounted on a microscope. Males preferably accompany fourth or fifth stage female copepodids during precopulatory mate guarding; only rarely are third copopodid stages guarded. Rare cases of males clasping juvenile males are also known. Males are active during mate guarding and constantly change the site of attachment of their antennules. This behaviour may ensure continued association of the adult male with the juvenile copepodid when the latter moults during the mate guarding phase. The final moult of the female, once observed only, lasts only 2 minutes. Copulation immediately follows but is preceded by the male’s control of the...

Phylogeny and biogeography of the Ergasilidae (Copepoda, Poecilostomatoida), with reconsideration of the taxonomic status of the Vaigamidae
Provedor de dados: 16
Autores: Pinto da Motta Amado, Maria Auxiliadora; Ho, Ju-Shey; Falavigna da Rocha, Carlos Eduardo.
Nineteen genera are currently considered valid in the Ergasilidae. A cladistic analysis was conducted on these genera and the five genera composing the closely allied Vaigamidae. Nineteen morphological characters were selected and polarized using Anthessius (Anthessiidae) as the outgroup. The most parsimonious cladogram (tree length = 60, Consistency Index = 0.50, Retention Index = 0.71), obtained through the use of the BB command in Hennig 86, is composed of eight major clades, with the five vaigamid genera composing the most derived clade. Based on Wiley’s (1981) “sequencing” convention, the five vaigamid genera cannot be placed in a family separate from the Ergasilidae. The biogeography of the ergasilid genera is discussed.

El rol del frente de mareas de Península Valdés en el control de la comunidad zooplanctónica
Provedor de dados: 20
Autores: Derisio, C.
The Península Valdés tidal front was studied in its rol in the control of the spatial distribution, abundance, assemblages, diversity and life histories of the zooplankton community using samples from two oceanographic surveys. Although the front showed in general high zooplankton abundances, highest values, mainly due to the presence of immature stages of copepods, were recorded in the transitional and stratified zones coinciding with highest values of chlorophyll a. The zooplankton groups showed a distinctive spatial distribution across the front. The results showed that this front did not exert any control on zooplankton composition and diversity, but did on the abundance. In the homogeneous zone the harpacticoid copepods were more abundant, followed by...

ABSTRACT Copepods have been successfully used in many countries for the biological control of larvae of mosquitoes that vector diseases. In Brazil, this line of research has been focused on the use of the copepod Mesocyclops longisetus (Thiébaud, 1914) for the biological control of the mosquito Aedes aegypti (Linnaeus, 1792). The transportation of the copepods from the place where they are reared to where they will be used often involves long distances for extended periods of time. This study assesses the survivorship of M. longisetus during simulation of transport under different conditions. Different loading densities (20, 30, 40, 80, and 120 ind.L) and stirring times (30 minutes, one hour, two hours, and four hours) were tested. Survivorship was high,...

Proposal of Tiddergasilus gen. nov. (Ergasilidae: Cyclopoida) for T. iheringi comb. nov. from the gills of Hoplias malabaricus (Erythrinidae: Characiformes) from Brazil
Provedor de dados: 103
Autores: Marques,Taísa Mendes; Boeger,Walter A.
ABSTRACT Ergasilus von Nordmann, 1832 is the type and the most speciose genus of Ergasilidae, with more than 150 valid species. The first species of this genus, Ergasilus iheringi Tidd, 1942, was described from the Neotropical Region, from the gills of Hoplias malabaricus (Bloch, 1794). Since then, 35 new species of Ergasilidae have been described from the Neotropics. However, a reanalysis of the available type specimens of E. iheringi revealed features that suggest that it represents a lineage independent from Ergasilus. Consequently, we propose Tiddergasilus gen. nov. (Ergasilidae: Cyclopoida) to accommodate T. iheringi (Tidd, 1942) comb. nov. The species was re-examined and redescribed based on available type specimens. Tiddergasilus gen. nov. is...

Diel vertical migration patterns of three zooplankton populations in a Chilean lake
Provedor de dados: 97
Autores: RAMOS-JILIBERTO,RODRIGO; CARVAJAL,JOSÉ L.; CARTER,MAURICIO; ZÚÑIGA,LUIS R.
In this work we analyzed the depth-distribution, at noon and midnight, of three zooplankton populations which are common inhabitants of lakes from central Chile and coexist in lake El Plateado. The species were Tumeodiaptomus diabolicus, Diaphanosoma chilense and Bosmina longirostris. Also, we analyzed the association between the depth-specific abundances of the groups and the depth-specific temperature and oxygen values during the sampling period. Our results show that: (1) the three population exhibited diel vertical migration during part of the year; (2) T. diabolicus and D. chilense exhibited the normal pattern of vertical migration, and B. longirostris presented both the normal and the reverse pattern; (3) for all species and most dates, zooplankters...

Microarthridion corbisierae sp. nov. (Harpacticoida, Tachidiidae), um novo copépode da meiofauna do litoral norte do estado de São Paulo, Brasil
Provedor de dados: 104
Autores: Kihara,Terue C.; Rocha,Carlos E. F.
Durante estudos sobre a diversidade de copépodes harpacticóides meiobentônicos marinhos, um novo representante da família Tachidiidae foi encontrado na plataforma continental interna do estado de São Paulo, entre o canal de São Sebastião e a área costeira em frente á praia de Ubatumirim, Ubatuba (23º24'S, 44º57,6'W). Material complementar foi coletado próximo à praia da Enseada, Ubatuba (23º30'S, 45º05'W). Embora esta nova espécie compartilhe com M. laurenticum (Nicholls, 1940) a redução das antênulas, ela pode ser facilmente distinguida de seus congêneres pela presença de apenas 2 artículos no endópodo da perna 4 e pela redução no número de cerdas internas do endópodo-3 das pernas 1-4 e do exópodo-3 da perna 3. Os Tachidiidae, que tipicamente habitam...

Psammocyclopinidae fam. n., a new monophyletic group of marine Cyclopoida (Copepoda, Crustacea), with the description of Psammocyclopina georgei sp. n. from the Magellan Region
Provedor de dados: 104
Autores: Martínez Arbizu,Pedro.
Psammocyclopina georgei sp. n. is described from submersed sands in the Magellan Strait, South Atlantic Ocean. This is the second species of the genus, previously known only from the Indian Ocean (Mozambique). Psammocyclopina Wells, 1967 is the sistergroup of Metacyclopina Lindberg, 1953. Psammocyclopinidae fam. n. is accordingly proposed to unify these genera into one monophyletic unit. The sistergroup of the new family is a cluster of cyclopinid genera composed of Cyclopinodes Wilson, 1932, Pseudocyclopina Lang, 1946, Parapseudocyclopinodes Lindberg, 1961, Hemicyclopina Herbst, 1952, Procyclopina Herbst, 1955, Heterocydopina Plesa, 1968, Neocyclopina Herbst, 1952, and an as yet undescribed new genus (Martinez Arbizu, in prep.).

The Metabolic Theory of Ecology (MTE) predicts that temperature is the main determinant of richness patterns for ectothermic organisms and that the relationship between richness (lnS) and temperature (1/kT) is a linear relationship with angular coefficient (b) near -0.65. This study tested the MTE for continental zooplankton diversity in 63 lakes in Brazil. Copepoda, Cladocera and Rotifera, as well as the three groups combined, showed different patterns from that predicted by MTE, with b values equal to 0.871, 0.516, 0.720 and 0.901, respectively. Temperature explains 12.7% of the richness of Copepoda, 5.3% of Cladocera, 6.7% of Rotifera, and 11.4% of all zooplankton groups...

O presente estudo apresenta uma análise ecológica das infrapopulações de ectoparasitas das cavidades nasais de Leporinus lacustris da planície de inundação do alto rio Paraná, Brasil. Duas espécies de ectoparasitas foram encontradas: o monogenético Rhinoxenus arietinus e o copépode Gamispatulus schizodontis. Os indicadores de parasitismo foram confrontados com comprimento-padrão, sexo e fator de condição relativo (Kn) dos hospedeiros. Foram também testadas diferenças nesses indicadores entre diferentes tipos de ambientes de coleta (lêntico, lótico e semilótico). Sugere-se a susceptibilidade de machos de maiores tamanhos à infecção por monogenéticos de cavidades nasais, em relação às fêmeas de tamanhos similares. O sexo, porém, não foi um fator determinante...

The goal of this study was to evaluate the concordance amongst three zooplankton groups (Rotifera, Cladocera, and Copepoda) and between the zooplankton groups and the environmental variables in the Luis Eduardo Magalhães reservoir, in the Mid-Tocantins River, Tocantins State, Brazil. Concordance patterns were found in relation to environmental variables, cladocerans, and rotifers, although values were relatively low. These results indicate that one should be cautious about the use of indicative taxonomic groups to detect environmental changes, where divergent results annul extrapolation possibilities and indicate the existence of distinct environmental factors controlling different groups.

Can nearby eutrophic reservoirs sustain a differentiated biodiversity of planktonic microcrustaceans in a tropical semiarid basin?
Provedor de dados: 42
Autores: DINIZ,LEIDIANE P.; MELO-JÚNIOR,MAURO DE.
ABSTRACT This paper aims to compare alpha and beta diversities of planktonic microcrustaceans from three reservoirs located nearby in a tropical semiarid basin. Our hypothesis was that alpha and beta diversities of the community are different, although the ecosystems are located close to each other. We carried out two sampling campaigns: dry and rainy seasons. The sampling of microcrustaceans and environmental variables (dissolved oxygen, chlorophyll a and nutrient) was performed at twelve stations and were distributed throughout the three zones (river, transition, and lacustrine), using a plankton net (45 µm). The reservoirs showed different uses and types of nitrogen predominance: Cachoeira (supply/nitrate), Borborema (sewage/ammonia) and Saco...

Provedor de dados: 42
Autores: DIAS,CRISTINA O.; ARAUJO,ADRIANA V. DE; BONECKER,SÉRGIO L.C.
In this study, we analyzed the main distributional features of Scolecitrichidae species in the Southwestern Atlantic Ocean (northern region of Rio de Janeiro State) and determined and described their habitat partitioning, based on a night series of stratified samplings down to a depth of 1,200 m. A total of 18 species from seven genera were identified and grouped according to their depth distribution. Distinct vertical patterns of total density, richness, diversity, and evenness were observed, with a decrease in density and an increase in diversity and richness with increasing depth. The total scolecitrichid abundance was dominated by a few epipelagic migrant species (Scolecithrix danae, Scolecithricella minor, Amallothrix tenuiserrata, and Lophothrix...

Provedor de dados: 49
Autores: Previattelli,Daniel; Perbiche-Neves,Gilmar; Menu Marque,Silvina; Rocha,Carlos Eduardo Falavigna da.
We present new records of Boeckella bergi at several water bodies in Argentina and Brazil. Within these records the northernmost and southernmost limits of occurrence of B. bergi in South America are included. The ample range of distribution is consistent with former studies, but it is more extensive than previously known. Observations on habitat preferences are also made. This species is tolerant to temperate climate conditions in this region of South America, with wide amplitude of temperature between summer and winter seasons, and irregular patterns of precipitation.

Provedor de dados: 52
Autores: Dias,Cristina de Oliveira; Bonecker,Sérgio Luiz Costa.
The aim of this work was to study the structure of the copepod community in relation to hydrographic conditions in Espírito Santo Bay, from 1993 to 1997. Zooplankton samples were obtained in the horizontal tows four times a year, using a 200 µm net. Temperature, salinity and dissolved oxygen were determined in the water samples. The overall mean density of the copepods was 9,085 ind.m-3 with the peaks exceeding 15,000 ind.m-3 in the summer and autumn during the first three years (1993 - 1995). The PCA analysis was used to relate the environmental conditions with the distribution of the copepods. The increases in the abundant species, namely Acartia lilljeborgi, Oithona hebes, Oithona oculata, Paracalanus quasimodo, Parvocalanus crassirostris and Euterpina...

Autores: Silva,Andréa Pinto; Neumann-Leitão,Sigrid; Schwamborn,Ralf; Gusmão,Lúcia Maria de Oliveira; Silva,Tâmara de Almeida e.
Mesozooplankton abundance and distribution at Suape Bay, Pernambuco, was studied to assess the impacts caused by the construction of an internal port to increase the capacity of the Suape Port Complex. Zooplankton sampling was done at 3 stations during the dry (November-December/1997) and rainy (April-May/1998) seasons. A plankton net with 300 µm mesh size was used. Wet weight plankton biomass ranged from 44 mg.m-3 to 3,638 mg.m-3. Forty-five macrozooplankton taxa were registered. The most abundant was Copepoda. Among copepods, Acartia lilljeborgi, Parvocalanus crassirostris, Oithona hebes, Corycaeus (C.) speciosus and Temora turbinata were most frequent. Minimum abundance was 9 ind.m-3 and maximum was 2,532 ind.m-3. Average species diversity was 2.55...

The aim of this study was to assess the effect of concentrations of imazethapyr, imazapic, and bispyribac-sodium herbicides on zooplankton community (Cladocer, Copepod and Rotifer) in rice paddy fields. The decrease of half-life dissipation (DT50) of the herbicides under study in water was: imazethapyr, imazapic, and bispyribac-sodium with an average of 3.75, 3.73 and 1.91 days, respectively. The mixture of imazethapyr with imazapic caused change in the analyzed zooplankton, with an increase in the densities of Cladocer and adult Copepod groups, while bispyribac-sodium caused a reduction of density in Copepod group, both adults and nauplii, in the initial samples. Among the groups, Rotifer was slightly sensitive to the herbicides.
