Of the 50 thousand or more species descriptions that exist in my reference library, there is very little change over 130 years in the basic vocabulary used to describe the shape or the ornament of the ostracode valves. Conodonts are rare in the Permian carbonates of Indochina but abundant conodonts and ostracodes have been obtained from turbiditic limestones of the Permian E-Lert Formation along with radiolarians from overlying cherts, all deposited on the margins of the interplatform Nam Duk Basin.

Investigations of the relationship between the ranges of oxygen and carbon isotope values of modern ostracode populations and their host water provide important information on local or regional conditions and influences. Here we present the first δ18Oostracode and δ13C of the freshwater ostracode species ... Fresh-water ostracodes from eight different sites on the San Francisco Peninsula were sampled periodically between May 1989 and May 1990. Seasonal variations in the relative abundances of ostracode species were observed. Those changes are believed to have been due, at least in part, to seasonal changes in water and sediment temperatures.Ostracode From Wikipedia, the free encyclopedia . Ostracodele (Ostracoda) (din greaca ostrakon = cochilie ; eidos = înfățișare) sunt o clasă de crustacee inferioare mici, de 1-10 mm, dulcicole sau marine.

An important form, such as Sinocypris funingensis Ho, 1982, is very similar to Hemicyprinotus watsonensis ...

Eighty-one ostracode taxa were identified in 81 samples. Changes in ostracode faunas in space and time provide information that enabled us to reconstruct a detailed paleobiogeography of the Bay. Ostracode migrations and faunal changes concomitant with sea-level changes and the opening of straits could be clearly identified on paleogeographical ...17.1. Introduction. Mangroves are intertidal forests distributed across the globe in tropical and subtropical regions. They thrive in protected tidal lagoons, embayment areas, and estuaries (Kennish, 1994).Carbon dioxide (CO 2) aids the growth of mangrove vegetation and nearly 70 mangrove species or hybrids of mangroves have been globally reported (Duke et al., 1998). ….

The "Bradleya problem" is concerned with the discovery and definition of a group of fossil and Recent reticulate ostracodes, several of which are common to Cenozoic deep-sea sediments in many parts of the world ocean floor.These species have often been misunderstood and taxonomically confused with genera characteristic of the study of shallow-water forms.Schwalb A, Locke S M, Dean W E, 1995.

Last, elsewhere, sediments on the slope and rise are more likely to move downward under the influence of mass-wasting processes and bottom density currents (Bouma 1979).Nevertheless, it fails to capture the full geographical (and climatic) ranges of many North American species, an issue which is addressed by Curry et al.
