A compilation of the ciliated species found on freshwater and marine ostracods as epibiont or parasite (endobiont) has been carried out based on published records. The checklist includes the taxonomic position of each species of epibiontic and endobiontic ciliate, the species of basibiont ostracodes, the geographic zones and the bibliographic references where they were recorded. Altogether 7 suctorian, 29 peritrich, one apostome and one scuticociliatid species were listed. Two of recorded suctorian species are possible specific to marine ostracodes, whereas only one, Tokophrya sibirica to freshwater hosts. Fourteen species of peritrichs are likely specific to freshwater ostracodes, while three possible specific to marine ostracode hosts. Other suctorian and peritrich ciliate species were found on a variety of host taxa. One species of scuticociliatid was recorded as endobiont in ostracod.

The present study analyzed the spatiotemporal changes of Ostracoda fauna in eight coastal lagoons in the Enez-Evros delta (Tuzla Lake 1, Tuzla Lake 2, Tuzla Lake 3, Taz, Işık, Dalyan, Kuvalak, and Taşaltı), located along the northern Aegean Sea coastline of Turkey. Recent ostracod samples collected from the eight lagoons were analyzed, and 16 living ostracod species (belonging to 14 genera) were identiﬁed during the sampling periods. The most abundant species were found to be Cyprideis torosa and Loxoconcha elliptica. C. torosa, a cosmopolitan and opportunistic species of Ostracoda, was found in all the studied coastal lagoons. All ostracod species determined in the lagoons were grouped into three assemblages: Group 1: halophilic continental freshwater species (F. fabaeformis, C. vidua, D. stevensoni, E. virens, H. salina, I. biplicata, I. bradyi, L. inopinata, and S. aculeata); Group 2: euryhaline and typical brackish water species (C. torosa and L. elliptica); Group 3: marine (coastal: A. convexa, L. rhomboidea, C. elongata, and X. communis) and brackish (lagoonal: L. lacertosa) water species. These species of Ostracoda were shown to be affected by environmental conditions. Analyses with the physicochemical variables and species (Spearman’s rank correlation coefficient and Canonical Correspondence Analysis) conﬁrmed that ostracod distribution in the Enez lagoons are controlled by seawater–freshwater inputs and by salinity. The purpose of this work is about to present data about of the Enez lagoons, and analyze the diversity of ostracods of them.

Badenian Ostracoda from the Pokupsko area (Banovina, Croatia)In this paper we present the results of the investigations on the Badenian (Middle Miocene) ostracods from the Pokupsko area. For the first time the presence of Badenian aged sediments in Croatia can be supported by the occurrence of ostracod biozonal markers. Four Badenian ostracod zones are established: Lower Badenian Biozone NO7Acanthocythereis hystrix-Bythocypris lucida, Middle Badenian Biozone NO8Eocytheropteron inflatum-Olimfalunia spinulosa, and the two Upper Badenian Biozones NO9Neomonoceratina laskarevi-Miocyprideis sarmatica elongataand NO10Carinocythereis carinata-Phlyctenophora farkasi.On the basis of the generally accepted paleoecology of selected genera, we identified the following ostracod faunas: shallow-water marine, shallow-water brackish-marine, shallow-water reef, and deep-water marine. The paleontological and trace element analyses suggest that the Pokupsko ostracod fauna lived in shallow (50 m deep), warm, and limpid waters, connected to a deeper sea and occasionally exposed to freshwater inflows.

Elemental mapping of Ostracoda valves to infer the paleothermometric fluctuations from off-Visakhapatnam, Bay of Bengal is the focus of the present paper. Two Ostracoda species such as Bairdoppilata (Bairdoppilata) alcyonicola and Actinocythereis scutigera were dominant throughout the core. The weight percentages of Mg, Sr, Ba, Fe and Mn in ostracod carapaces were estimated and the ratio with respect to Ca was analyzed to decipher the paleoclimate and oxy-redox conditions. It is observed that trace element accumulation varies with respect to different ostracod species and shell position. Thus, the elemental mapping of the ostracod carapaces by the EDS techniques proved as a primary proxy to decipher the paleotemperature fluctuations in the study area.

Of the three superfamilies of Ostracoda present in fresh water, only the Cytheroidea had thus far no records in terrestrial environments. Here, we report on a new genus and species, Intrepidocythere ibipora n. gen. n. sp., of the ostracod superfamily Cytheroidea, from forest leaf litter in São Paulo State, Brazil. Judging from morphological similarities, this new genus is believed to be closely related to the genus Elpidium. Possible pathways that led to the colonisation of terrestrial habitats are discussed, and an overview is given on the distribution of the known terrestrial ostracod lineages. The present findings strengthen the idea that terrestrial ostracods are more common than previously thought, at least in tropical areas.

A micropaleontological analysis on 15 beachrock samples from the Northern sector of Rio Grande do Sul Coastal Plain (RSCP ), southern Brazil , revealed a relatively diverse and well-preserved ostracod assemblage composed of 16 species , including Cyprideis multidentata Hartmann, Callistocythere nucleoperiscum Whatley et al., Cytheretta punctata Sanguinetti, Caudites ohmerti Coimbra & Ornellas , and Argenticytheretta levipunctata Sanguinetti et al. Eleven ostracod species are left in open nomenclature or tentatively identified . Besides ostracods , some foraminifers , echinoderm spines, and fish remains (teeth) were also recovered ; however , the scarcity of specimens or poor preservation precluded identification at species level. Based on the Ostracoda taxonomic composition it is proposed that the beachrocks characterize environmentally condensed assemblages . This preliminary study reveals the importance and potentiality of micropaleontology for understanding the processes involved in the formation of beachrocks. Keywords: Pelotas Basin, Quaternary, coastal environments, micropaleontology, taphonomy.

Representatives of the Class Ostracoda are widely used as tools in applied paleoecological and biostratigraphical studies in all continents. In the Araripe Basin, located in the northeastern of Brazil, the Romualdo Formation is one of the most studied, not only for the preservation but also for the abundance of its fossils. The ostracod genus Pattersoncypris Bate, 1972 is well-represented in this formation and it is the most abundant, which reinforces the importance of its taxonomic study. In this work, Pattersoncypris minima sp. nov. is described for the Romualdo Formation as a contribution to the knowledge on Brazilian Cretaceous non-marine ostracods. Taphonomic aspects are also presented, considering the complete ontogenetic stages of the material.

In the present study, we test the relevance of a number of environmental factors on alpha and beta ostracod diversities, at species and family level. Ostracods were sampled from several substrates, including sediment and root systems of various floating aquatic macrophytes, from 48 environments (both lentic and lotic habitats, ranging from the river itself, over connecting channels linking with open lakes, and, finally closed lakes), belonging to four different systems (Paraná, Ivinheima, Baía and Taquaruçu), in the alluvial valley of the Upper Paraná River. The faunistic survey recorded the presence of 54 species of Ostracoda, belonging to the families Cyprididae, Candonidae, Limnocytheridae and Darwinulidae. Various diversity estimators indicated that these recorded levels of specific diversity should be close to true values. Higher values of ostracods species richness (alpha diversity) were observed in the Baía and Ivinheima systems, while lotic habitats were richer than lentic ones. In addition, open lakes appeared to be more affected by the variable 'system' than closed ones, which can to some extend be explained by the putative effects of flood pulse on benthic communities. The two investigated factors have different effects on the four ostracod families. The present study also indicated that there is a large homogeneity within and between systems, as exemplified by the low beta-diversity levels.

During examination of the large ostracode assemblage collections at the Department of Scientific and Industrial Research, Geology & Geophysics, Lower Hutt, New Zealand, a single specimen of unusual shape was encountered. So unusual is the crescentic outline and infolding of the entire shell periphery that assignment even to a phylum was difficult, and it was only upon scanning electron microscopic study that subcentral muscle scars were clearly observed and these enabled confident identification of the specimen as an ostracode. One specimen is not usually considered sufficient to propose a new taxon; however, in this case there is no doubt that this unique specimen clearly represents a new species, genus, and probably family of Ostracoda. A search for additional specimens from the type unit is underway, but has, as yet, been unsuccessful to find this rare intriguing ostracode. Unlike other unusual ostracodes described from the Southern Hemisphere such as the punciids, this specimen appears to have no similarity with Paleozoic taxa.

Os ostracodes são microcrustáceos predominantemente bentônicos que deixaram rico registro fóssil, constituindo-se em importante ferramenta para a interpretação paleoambiental e bioestratigráfica. Estudos que tratam dos ostracodes recentes são de grande importância à Paleomicrontologia, pois muitos gêneros e até mesmo espécies do Cenozoico ainda são encontrados nos mares atuais. Diversos estudos versam sobre os Ostracoda na plataforma continental e talude superior no Brasil, mas são raras as pesquisas nas águas mais rasas do infralitoral. O principal objetivo deste estudo foi identificar e ilustrar a riqueza de espécies ao longo de uma ampla área litorânea do sul do Brasil, cuja costa é formada por numerosas pequenas praias guardadas por promontórios rochosos. Discutir aspectos relacionados à zoo- e à paleozoogeografia em especial dos elementos autóctones desta ostracofauna, além de introduzir a discussão sobre a fidelidade composicional entre associação viva e morta na área de estudo, estão entre os objetivos subsequentes.Dezoito famílias, 33 gêneros e 46 espécies foram identificados nesse estudo. A família Hemicytheridae é a mais representativa com 18 espécies, seguida por Cytheruridae com seis espécies. Duas espécies do gênero Xestoleberis Sars foram identificadas como prováveis novos táxons para Xestoleberididae. Preliminarmente, a fidelidade composicional é baixa, com maior riqueza na associação morta, bem como grande dominância e baixa riqueza na associação viva, um padrão esperado para zonas marinhas rasas como o infralitoral.
Ostracoda are microcrustaceans with predominantly benthic habit which exhibit an abundant fossil record and constitute an important tool for paleoenvironmental and biostratigraphic studies. Research about recent ostracodes are extremely relevant to Paleomicrontology since many genera and even species from Cenozoic are still found nowadays. Several studies on Ostracoda from Brazil have focused on continental shelf and upper slope. The present work aims to identify and illustrate the species richness over a broad coastal area from southern Brazil, which coast is represented by numerous small sandy beaches guarded by rock promontories. Also, discuss zoo- and paleozoogeographic aspects, mainly related to autochthonous elements of this ostracofauna, and to introduce the discussion of compositional fidelity between living and dead ostracode assemblages, are among the subsequent objectives. Eighteen families, 33 genera and 46 species were identified. The family Hemicytheridae is the most representative with 18 species followed by Cytheruridae with six species. Two Xestoleberididae species herein identified are probably new taxa. A preliminary analysis showed low compositional fidelity with richness higher in death than in living assemblages. The living assemblage showed high dominance and low richness. This pattern is common for shallow marine zones such the infralittoral.

Freshwater ostracods are potentially useful for environmental monitoring and, since their calcified valves may be preserved in lake sediments, are also valuable in palaeolimnological studies of environmental pollution such as eutrophication and surface water acidification. To establish a data-base of ostracod ecology, biannual survey work in 1989-1990 was performed in 75 lakes and tarns of a wide range of physico-chemical characteristics in the Lake District in Cumbria, ranging from large eutrophic lakes such as Windermere and Ullswater to tiny, upland acidic tarns. pH ranged from 4.3 (Black Pool) to 8.0 (Browns Tarn). Littoral margin samples were taken from all 75 sites and yielded 31 ostracod species, of which 8 were new to the Lake District fauna. The collection of multiple littoral samples from two sites demonstrated that a single sample produced an adequate faunal representation if it encompassed a variety of microhabitats. Statistical analysis, incorporating a multistage, multivariate technique, has shown that 18 species make up over 99% of the data set, and that 5 species, Cvpria ophthalmica, Cvclocypris ovum. Metacvpris cordata. Candona Candida and Cvpridopsis vidua. dominate the community in 71% of the sites containing ostracods, forming eight distinct assemblage groups. No ostracods were found in 13 of the 75 sites, 11 of which were acidic, having a pH of below 5.7. Equations were derived to predict both species distribution and diversity. Important predictors of community structures were shown to be pH, [Ca] 2+ , [Mg] 2+ , substrate, lake size and altitude. The equations were tested by further sampling of additional sites in the Lake District. Predictions of total species number and density generally provided an excellent fit to the observed data, although individual species predictions were poorer, especially in alkaline conditions. Substrate was not included in the analysis, due to quantitative difficulties, but this factor must be included in future predictive models as it was shown to be an important parameter in determining distribution. Deep-water sampling was carried out in 6 lakes. 10 species were collected, including Candona necrlecta, which was absent in the littoral samples. 9 species contributed to over 99% of the data set, and 2, Cypria ophthalmica and Candona Candida dominated the community in 75% of the sites containing ostracods. Community structure was predominantly determined by water depth (together with the associated temperature effect) and substrate. The sex ratio of Cyclocvpris ovum was shown be biased towards the female only at high alkalinities. Other species had sex ratios biased towards the male or female, the values independent of water quality. Large, swimming ostracod species were absent in sites containing fish. A series of laboratory experiments using three species of Ostracoda, (Cvpria ophthalmica. Cvpricercus fuscatus. and Eucvpris virens), and a predator (Gasterosteus aculeatus) correlated increasing ostracod size with an increased rate of predation, suggesting that predation could limit ostracod distribution. From the results of principal component analysis, it was concluded that the main characteristics that chemically differentiate the sites are calcium, magnesium, hydrogen and sodium ion concentrations. Toxicity tests were used to expose selected species to a wide range of calcium, magnesium, sodium and aluminium concentrations, at both neutral and acidic pH levels. Aluminium was selected as it has been highlighted as a major factor in the toxicity of acid waters. All species tolerated a wider spectrum of ionic concentrations than those in which they were recorded in the field, although the order of species survival in the experiments was similar to that found in the Lake District. It is suggested that whilst adult Ostracoda do not suffer from the acute toxicity of pH or aluminium, they may be unable to successfully reproduce in harsh environmental conditions. The waters of the English Lake District are not particularly species-rich due primarily to low alkalinity and low levels of dissolved cations, but also because they are cold. Only in small, ion-enriched pools is ostracod density sufficiently high to warrant their consideration as important detritivorous contributors in the cycling of nutrients. The Lake District fauna is compared with those recorded in other parts of Britain and Europe.

A global extinction event has been documented in protozoan foraminifera in the late Pliocene to Pleistocene. The timing of the extinction event varied depending on location, however for Ocean Drilling Project Site 1125, disappearances occurred between 2.5 and 0.57 Ma, with the major decline approximately 1.1 Ma. In order to determine if this event affected benthic organisms other than protozoans, this study was undertaken to determine how podocopid ostracods (Crustacea) recovered Ocean Drilling Program Site 1125 responded. The present study was hindered by the small number of valves recovered; the fact that a large proportion of taxa found were undescribed and new to science; and the current state of taxonomic scheme that is under significant revision. These factors meant that a comprehensive comparison could not be achieved. Despite this, counts of ostracod valves and assessments of diversity from this study reveal a significant increase in both parameters from approximately 900-600 ka. Three possible causes were investigated to account for this increase, sediment type and sample size; affects of taphonomy, mainly dissolution; or an actual biotic 'event'. Statistical analyses showed that although sample size did have some effect, it was not the sole reason for the increase in ostracod numbers. Dissolution had an expected affect on the percentage of juveniles but no correlations were found with other sample characteristics. Sedimentation rate was investigated but this also proved unrelated. Therefore, it is suggested that the increase in total ostracod valves and diversity which occurs between 900 and 600 ka was in fact a natural, biotic 'event'. This preliminary evidence suggests that an oceanographic event that has negatively impacted on the foraminifers has had the reverse affect on the ostracod assemblage, in the sense that both population size and diversity increase during that time.

Resumo:

The Sakmarian (Cisuralian, Permian) Fossil Cliff Member of the Holmwood Shale is situated in the northern Perth Basin, Western Australia, and consists of alternating beds of shale and silty calcarenite forming three parasequences. Within this member a diverse fauna of ostracodes and foraminifera are present. During the Cisuralian the northern Perth Basin formed part of the Gondwanan supercontinent and was linked to Greater India via an epeiric sea that opened to the north. The ostracode fauna is restricted to the calcareous beds of the member and consists of a diverse benthic fauna comprising 31 new species and 13 previously recorded species. Species from the Healdioidea, Bairdioidea, Youngielloidea, and Thlipsuroidea dominate the assemblage and suggest a normal-marine environment during the period represented by the calcareous beds, with an overall shallowing trend up the sequence. The fauna shows some similarity to faunas from the Tethyan deposits of North America and the Boreal deposits of Russia during the Late Carboniferous and Cisuralian. Twenty-eight species of foraminifera were recorded from the Fossil Cliff Member and underlying Holmwood Shale and comprise two distinct faunas, an agglutinated benthic foraminiferal fauna found within the shale beds and a calcareous benthic foraminiferal fauna present in the calcarenite units. The agglutinated foraminifera are inferred to represent deposition in dysoxic to suboxic (0.1-1.5 mL/LO2;), poorly circulated bottom waters below wave base. The calcareous foraminifera are inferred to represent deposition in normal-marine conditions. Both foraminiferal assemblages show a shallowing trend in their distribution that matches the trend identified in the ostracode fauna. Based upon the palaeoecology of the ostracode and foraminiferal faunas, the depositional environment for the Fossil Cliff Member is inferred to have been within shallow water in an epeiric basin during an overall marine regression that is overprinted by eustatic and isostatic oscillations resulting from deglaciation that occurred during the early Sakmarian (Cisuralian). These sea-level oscillations raised and lowered the oxic surface waters of the epeiric sea above and below the substrate resulting in a sparse agglutinated foraminiferal fauna or an abundant and diverse ostracode and calcareous foraminiferal fauna respectively.

A study of the ostracode fauna from the Silurian of Norway has been undertaken. All of the taxa recoverd and described are from the Llandovery and Wenlock Series; one species from the topmost part of the Ordovician of the Oslo region is also figured. Research has concentrated particularly upon the Palaeocopa Henningsmoen, 1954, but also includes the Leperditicopida Scott, 1961. The 'non-palaeocopes', because of particular problems related to preservation and taxonomy, are not treated as extensively. Primary revision has been made wherever possible. Such work has been augmented by studies of extensive new collections made from throughout the Oslo region, particularly from the Ringerike, Oslo-Asker and Holmestrand districts. This study has concentrated firstly on the taxonomy of the fauna. There are chapters on the Leperditicopa, Palaeocopa and 'non-palaeocopes'. Other chapters deal with the palaeoecology, biostratigraphy and correlation and affinities of the fauna. A full faunal and associated locality list, together with information on regional stratigraphy, is also presented. The fauna is 26 genera (2 new), 43 named species (14 new) and 15 other forms are described under open nomenclature. The Silurian ostracode fauna of Norway is mostly endemic (at specific level) but does have affinities with Gotland, Siberia and Britain. Ostracode potential for correlation between various districts of the Oslo region is best realised in the Steinsfjorden Formation. Standard micropalaeontological techniques have been used throughout, with most material being prepared by 'Vibrotool', and photographed on the Scanning Electron Microscope.

Resumo:

Estudos recentes têm demonstrado significativas variações na composição da fauna de ostracodes batiais decorrentes de mudanças climáticas. Visando verificar como esses eventos afetaram a ostracofauna batial da bacia de Campos foram analisadas 15 amostras provenientes de um testemunho a pistão recuperado a 1.287 m de lâmina de água. Espécies alóctones e autóctones foram identificadas sendo apenas as últimas estudadas. A idade das amostras foi obtida com base na análise de isótopos estáveis de oxigênio em testas do foraminífero planctônico Globigerinoides ruber, e os resultados comparados com dados do SPECMAP (Spectral Mapping Project). Foram identificadas 50 espécies autóctones distribuídas em 26 gêneros e 17 famílias. Os gêneros Krithe e Cytheropteron foram os mais diversificados (sete e cinco espécies, respectivamente). A família mais diversificada foi Cytheruridae, corroborando outros estudos paleoceanográficos. Foi estabelecida a idade de 42 ka para a base e 200 anos para o topo do testemunho. A análise de agrupamento por similaridade de Jaccard dividiu as amostras em dois grupos separados na amostra 12 (17,3 ka), no limite Holoceno-Último Máximo Glacial. A diversidade oscilou significativamente entre períodos glaciais e interglaciais, sendo menor no primeiro (3,0 nats/ind-1) e maior no último (3,4 nat/ind-1). Foi observado o predomínio de Argilloecia e Cytheropteron durante a deglaciação, Saida no interglacial, Apatihowella no UMG, Krithe no glacial e Macropyxis durante o UMG e glacial. Xestoleberis, por sua vez, ocorreu com diversidade relativamente constante ao longo de todo o testemunho. A distância taxonômica entre as espécies que ocorrem no glacial e interglacial se mostrou dentro dos limites esperados, com pequena proximidade entre os limites superiores e inferiores, respectivamente. A fauna de ostracodes da Bacia de Campos respondeu às variações climáticas ocorridas no Quaternário, o que reforça seu grande potencial como indicadora de mudanças paleoceanográficas.

With the objective of assess the influence of these events on the bathyal ostracodes from Campos Basin, 15 samples from a piston core taken at 1,287 m water depth were studied. Both allochthonous and autochthonous species were identified, however, only the latter were analyzed. The age of the samples was determined based on oxygen stable isotope data from tests of the planktonic foraminifer Globigerinoides ruber and compared to SPECMAP (Spectral Mapping Project) ones. Fifty autochthonous species belonging to 26 genera and 17 families were identified. The genera Krithe and Cytheropteron were the more diversified (seven and five species, respectively), while Cytheruridae was the most diversified family, supporting other paleoceanographic studies. The core bottom was dated as 42 ka, and the top 200 years. The Jaccard similarity grouping analysis shared the samples into two groups being the sample 12 (17.3 ka) the limit between them, which corresponds to the Holocene-Last Glacial Maximum transition. The diversity varied significantly between glacial and interglacial periods, being lower in the former (3.0 nats/ind-1) and higher in the latter (3.4 nat/ind-1). The predominance of Argilloecia and Cytheropteron during the deglacial, Saida during the interglacial, Apatihowella during LGM, Krithe on glacial, and Macropyxis during the glacial and LMG was recorded. Xestoleberis was registered with steady diversity values along the core. The taxonomic distances between the species in the glacial and interglacial presented ordinary values, with small distance between the upper and lower limits, respectively. The ostracode faunas from Campos Basin responded to the Quaternary climatic events, reinforcing the use of deep-sea ostracodes changes as a paleoceanographic proxy.

Resumo:

This paper presents the feeding habits of specimens of the fish Alburnus alburnus (L.) that inhabit the Gruža and Gazivode reservoirs. The diets of 37 specimens from Gruža reservoir and 44 specimens from Gazivode reservoir were analyzed. The common bleak from Gazivode reservoir fed more diversely on eight different prey items, while six different prey items were identified in specimens from Gruža reservoir. The most common prey in the diet of specimens from both reservoirs is Bosmina sp., which was present in every digestive tract studied. Very common prey items are also Daphnia sp. and Cladocera. In contrast to the specimens from Gruža reservoir, the specimens from Gazivode reservoir feed on both Leptodora kindtii and insects. The specimens from Gazivode reservoir also feed on Ostracoda at a much higher percentage than the specimens from Gruža reservoir. Numerous reports in the literature have confirmed that common bleak feed mainly on zooplankton and often on insects, as shown by our results.
