A review of the phylogeny of the Haptophytacharacteristic filamentous appendage, the haptonema, arising between the two flagella. We have amassed small subunit rRNA gene sequences (18S rDNA) from 125 haptophytes and aligned the sequences with those of over 300 published and unpublished chlorophyll a+c algae. Phylogenies were constructed usin

Coccolithophorid biodiversity: evidence from the cosmopolitan species ,ast two separate species . and ., characterized by differences in their coccolith morphology, life cycle, distribution, ecology and molecular genetics. This situation, which may be common in the coccolithophores, challenges our view of biodiversity and spe-ciation in this important marine phytoplank

細節(jié)

Species level variation in coccolithophoresumented and their biomineralised periplasts – the coccoliths – provide a rich suite of qualitative and quantitative morphological characters and a uniquely extensive fossil record. In addition, extant coccolithophore species can be grown in culture and hence are available for studies of morphologica

Coccolith contribution to South Atlantic carbonate sedimentationtion of carbonate production of the different organism groups. In this chapter we firstly review the carbonate distribution patterns of both bulk coccoliths and planktic foraminifera, estimated by means of different carbonate calculation techniques. These studies clearly reveal a variable pattern of

Biogeography of selected Holocene coccoliths in the Atlantic Oceanan. The mapping is based on surface sediment samples. Each of the taxa considered here constitutes an unambiguous morphological group ideal for rapid low taxonomic resolution analysis of assemblages, which is a tempting strategy for ecological and paleoecological analysis of assemblages. However, in
