Abstract:

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 fres

Abstract:

In recent decades, research on ostracodes has grown dramatically. While many aspects of the group have been investigated, this review focuses on the paleoenvironmental applications of ostracodes from marine and nonmarine environments. It is argued that while ostracodes have great potential as paleoenvironmental tools, much of that potential has not yet been fully realized because of our imperfect understanding of ostracode biology, taxonomy, systematics and ecology. Future developments will be sure to result from additional studies in these areas, and will also be effected by exchange of ideas

Abstract:

Leperditiocope ostracodes identified asSollenella? sp. were discovered in the Gilboa Formation (upper Givetian, uppermost Middle Devonian) within the continental Catskill Magnafacies of New York State. The deposits in which the ostracodes were found are meandering-fluvial facies that were part of a vast alluvial plain that sloped westward from the eroding Acadian Mountains. Hence, ostracodes colonized freshwater habitats earlier than heretofore thought. It has been widely accepted that, until now, the oldest known unequivocal occurrences of freshwater ostracodes are of Late Carboniferous age.

Abstract:

The shell chemistry of ostracodes is a useful indicator of past environmental conditions especially when the chemistry data are considered along with other proxy data. The complexities involved with the chemical and isotopic changes accompanying hydrologic change, solute evolution, and the autoecology of ostracodes all point to the need to exercise caution when interpreting shell chemistry. Nevertheless, the stable-isotope values and cation ratios (e.g., Mg/Ca, Sr/Ca) as well as the species assemblage of ostracodes can provide powerful tools for the reconstruction of paleoclimate and paleohydr

An ostracode fauna is recorded from the Patti Formation (Late Cretaceous) of Vridhachalam area, Tamil Nadu. The assemblage includes Bairdia pentagonalis, B. cretacea, B. supplanata, Macrocypris limburgensis and Paracypris limburgensis, which are typical of Maestrichtian age. The ostracodes show strong affinities with those recorded from the Ariyalur and Pondicherry areas, and those described from the type-Maestrichtian of Holland. The above assemblage and the presence of distinct Paleocene ostracodes in the overlying Pondicherry Formation throw light on K/T transition in the Vridhachalam area.

Ostracodes are bivalved Crustacea whose fossil shells constitute the most abundant and diverse metazoan group preserved in sediment cores from deep and intermediate ocean water depths. The ecology, zoogeography, and shell chemistry of many ostracode taxa makes them useful for paleoceanographic research on topics ranging from deep ocean circulation, bottom-water temperature, ecological response to global climate change and many others. However, the application of ostracodes to the study of climate change has been hampered by a number of factors, including the misconception that they are rare or

Climatic effects on aquatic environments are an important factor in the ecology of ostracodes judging from their biogeography especially with respect to moisture balance and ecoregions (vegetation zones). The importance of climate in controlling ostracode distribution is underscored by major ecological changes indicated by co-stratigraphic changes in ostracode and pollen biozones throughout the Quaternary. Climatic interpretation of ostracode records are complicated, however, by several non-climatic factors, including basin shoaling, changes in water chemistry due to abrupt changes in the flux

Focus is on nonmarine ostracodes which are generally poorly ornamented so that their carapaces offer few landmarks for characterization of morphological change

Domatial dimorphism is manifested by a special domiciliar space for egg/brood care in females. Domatia are represented by a loculate domiciliar wall or by a more generalized space bounded anteriorly by an interior partition caused by thickening or folding (sulcation) of the shell wall.

Abstract:

This study is based on 62 samples of phytal and bottom sediments collected along rocky beaches (< 3 m water depth) of the central and northern coasts of the state of Santa Catarina (26Âº10'/27Âº50'S â€“ 48Âº26'/48Âº40'W), southern Brazil. Living and dead ostracodes distributed among 16 families were recovered. In this paper is emphasized one new hemicytherid genus and species that is described and richly illustrated: Auricythere sublitoralis gen. nov. and sp. nov. Some ecological and zoogeographical aspects of this new ostracode are briefly discussed.

Abstract:

Eleven stygobitic myodocopid ostracodes (two new–Danielopolina palmeri and Spelaeoecia hox) in the Order Halocyprida are reported from anchialine waters in 11 inland blue holes in Bahamas. One stygobitic halocyprid ostracode is reported from two localities in Bermuda, and one from a cave in Mexico. A new subfamily, Spelaeoeciinae, is proposed to contain the genus Spelaeoecia, and the subfamily Deeveyinae is elevated to family status. Two new species of cladocopid ostracode (Pseudopolycope helix and Pontopolycope storthynx), are described from a cave in Mexico and an oceanic blue hole in the Ba

Abstract:

Ostracodes are among the most useful groups of fossils for applications in paleogeography and plate tectonics, mainly because of their provincial distributions. Analyses by many workers of the distributions of some groups of ostracodes, typically cytherocopine taxa at the generic level, demonstrate that shallow marine ostracode faunas may differ markedly in coeval deposits, even within short geographic distances. These analyses indicate that many shallow marine taxa are unable to cross deep water barriers. An intimate relationship exists, therefore, between plate tectonics and biological evolu

AbstractBetween 10,500 and 9000 cal yr BP, δ18O values of benthic ostracodes within glaciolacustrine varves from Lake Superior range from − 18 to − 22‰ PDB. In contrast, coeval ostracode and bivalve records from the Lake Huron and Lake Michigan basins are characterized by extreme δ18O variations, ranging from values that reflect a source that is primarily glacial (∼ − 20‰ PDB) to much higher values characteristic of a regional meteoric source (∼ − 5‰ PDB). Re-evaluated age models for the Huron and Michigan records yield a more consistent δ18O stratigraphy. The striking feature of these records

AbstractSexual dimorphism is common in many extant animals, but it is difficult to demonstrate in fossil species. Working with material from the Late Cretaceous of the U.S. Coastal Plain, we herein analyze sexual dimorphism in ostracodes from the superfamily Cytheroidea, a group whose extant members have males that are relatively more elongate than females. We digitized outlines of more than 6000 individual ostracode valves or carapaces, extracted size (area) and shape (length-to-height ratio) information, and used finite mixture models to assess hypotheses of sexual dimorphism.

Samples from shelf-edge and lower-bathyal working areas are examined. The results show (1) distinct MUC and EBS faunas due to the large difference in mesh size of MUC and EBS; and (2) distinct shelf-edge and lower-bathyal ostracode faunas.
