The coccoliths are either dispersed following death and breakup of the coccosphere, or are shed continually by some species. ... Biogeography: In Pacific, occasional to common in Central and Transitional Zones. (2001). Phycodnaviridae is a family of large (100–560 kb) double-stranded DNA viruses that infect marine or freshwater eukaryotic algae. Detecting soluble Ca phases other than free Ca 2+ inside cells is incompatible with traditional light, fluorescence, and electron microscopy, and requires the use of specialized techniques ( 22 ). 280463. 76. These chemical compounds, known as alkenones, can be found in marine sediments long after other soft parts of the organisms have decomposed. Emiliania huxleyi (Haptophyta) is the most ubiquitous and abundant coccolithophorid in modern oceans [ 2 ], and forms extensive coastal and mid-oceanic mesoscale blooms at temperate latitudes [ 3 ].
